CasparCG has been developed as an Open Source project since 2006. Now, as SVT is looking for a broader collaboration with other public broadcasters, we have recently adopted a new Open Source policy that encourages developers to be more active in the Open Source community. Both by contributing to existing projects and by releasing in-house developed projects as Open Source. In our talk we will present how SVT came to adopt this new Open Source policy, the challenges faced in getting it accepted within the organization, and how it has played out so far. We will also talk about how SVT encourages developers to contribute to Open Source projects and release their own code as Open Source, and why working with Open Source is essential for a public service broadcaster company. --- Josef is an Open Source enthusiast that has been active in many areas of the Open Source communities. As a translator, code contributor to various projects, with licenses and Open Source strategy, arranging hackathons and as a writer for tech magazines. Currently, Josef is working at SVT as a senior developer, and is also a member of their newly formed Open Source lead team that is working with implementing an Open Source mindset in the organization. Armin is a software engineer, Open Source enthusiast and proud dad. Currently working at SVT (his second home) as a Product Owner responsible internally for CasparCG as platform and additional solutions. Community manager for the amazing Open Source project CasparCG. Striving always to release existing or new products as Open Source and he has no plans to change his mindset in that question.https://conf.tube/videos/embed/ec9d2504-62fc-4871-a4c3-035d5776c61ehttps://conf.tube/w/3BN5YhkivSftQJ6ESS5X6ehttps://conf.tube/lazy-static/thumbnails/1531b5e9-2e1d-44d0-b55d-9d32ecf7caeb.jpgDocs or it didn't happen! - Mikey ArielIf you ever skimmed through a README, tried to follow a quickstart tutorial, attempted to decipher an error message, or typed '--help' in your console, congratulations -- you have encountered documentation! Long gone are the days of massive books with never-ending stories about your software. Today's users are smarter and less patient, which means that we no longer need to document *all the things*, as long as what we do document is clear, concise, helpful, and accessible. And that's where the real work starts. Documentation requires some attitude adjustment, since prose doesn't neatly compile into binaries as code does. But Don't Panic(tm)! No matter what your role is, you can apply a few key principles from the technical writing world to make your project more docs-friendly, and therefore more user- and contributor-friendly. --- Mikey (a.k.a. ""That Docs Lady"") spent the better part of the last 10 years documenting super-geeky enterprise software, most recently for OpenStack Platform at Red Hat. She is also on the global core team for Write the Docs, Django Girls alumni, co-author of the Happiness Packets project, and documentation coach for open-source projects. Since joining the open-source family in 2013, Mikey has been giving talks and writing articles about docs, DevOps, and community. She regularly runs documentation workshops, hackfests, and help desks at developer conferences.

Authenticating your single page apps using JSON Web Tokens - Sam BellenWhen it comes to writing code, there’s nothing we take more serious than authentication and security. Modern single page applications bring along new challenges. By using solutions like the OpenID Connect protocol and JSON Web Tokens we can improve the user experience when authenticating with your apps, providing a seamless authentication process. In this talk I will try to explain in depth, the way JSON Web Tokens work and can be used to secure your single page apps. I will explain the difference between using opaque tokens and JWTs. The talks will also give an overview of a modern authentication flow and a step by step breakdown of how it works exactly. No specific previous knowledge is required, but it helps the audience has some experience with authenticating users. I'm Google Developer Expert who works as a Developer Evangelist at Auth0. At Auth0 we're trying to make authentication and identification as easy as possible, while still keeping it secure. --- After office hours I like to play around with the web-audio API, and other "exotic" browser API's. One of my side projects is a library to add audio effects to an audio input using JavaScript.

As our lives continue to become increasingly managed by our devices, we need to ask ourselves what we're gaining--and what we're giving up--by allowing technology into the spaces that make our hearts ache and that keep us up at night. This talk will weave together two narratives essential to many people: health and love. It will examine the ways in which both of these topics have become entwined with computing, what that means for us as individuals, and what that means for our individual and societal user freedoms. --- Molly de Blanc is a free software activist.

The FOSS community implements standards. The FOSS community also develops industry standards. How does this the interaction function? And is it working well? How do policy makers interact with the FOSS community to set safety standards and other requirements? What is the relationship between standards-essential patents and FOSS? What comes first, specification or implementation? Where does innovation happen, and what is the platform to develop consensus on technical standards in a market segment? Based on research work at TU Berlin and for the Joint Research Center of the European Commission and the work of the Open Invention Network to protect key FOSS projects from patent litigation, the presentation will discuss the current state of the debate at the European and international level, and provide an outlook on how the roles and functions of standards-development organisations and the wider FOSS community are converging.

Most of the value that the conductor (community manager) brings to the orchestra (community) is carried out before the performance (behind the scenes). In this session, I will share my experiences in orchestras and open source communities big and small across different countries.

Other things are hidden from everybody. Yet some can be obvious to an experienced DBA, but come as a big surprise to application developers, and these can often be different between different databases.

We - a UX Designer and a Software Engineer - will introduce you to the concept of WebComponents, and how we can achieve order through evolving from Bootstrap to CSS grid based design system. Target Audience: designers and engineers. our talk introduces the importance of collaboration and bringing designers and engineers together. The Red Hat portfolio includes about 50 different products. There was a need for a design system as different patterns were build over and over again which led to inconsistency. The UXD goal is to bring consistent user experience to the entire Red Hat portfolio. This talk explains why it is important to have a unified look and feel. Patternfly is an open-source design system that helps our designers and engineers build user friendly products. As the frontend technologies are constantly evolving, this design system has to evolve with them. We would like to talk about the history and evolution of PatternFly - how it was created and how it tries to handle the continuous evolution of the frontend landscape.

Maybe it was a negative integer, strange timezone conversion behaviour, off by one error or something entirely else. These subtle bugs are often hard to catch and are easily missed in test cases. You like me have probably ran into plenty of code utilising only happy path testing, only to later discover subtle bugs which are easily fixed once pointed out. This is where property based testing comes into the picture. In this talk I will focus on a wonderful Python library called Hypothesis but the concepts apply to other languages as well. Hypethesis is based on the same concept as the famous QuickCheck library for Haskell, which in turn have been ported a large number of languages. Hypothesis uses a wide range of input to find edge cases that you could otherwise easily miss, once it finds these cases it narrows down the input to the minimal breaking example to provide failures which are easier to understand. --- Alex is technologist by hearth and have been working in the industry for the past 10 years and were contributing to open source prior to that.

Most computers are not desktop, laptops, tablets or mobile phones, but microcontrollers. Small, integrated systems with a few KB of RAM. And their presence is ever growing. Last year alone 31 billion (!) of them were shipped, up from 23 billion in 2015. And they get more capable every day. A modern embedded system has threads, can run Python or JavaScript, and use machine learning models. Why are you not developing for them yet? In this talk you'll learn that microcontrollers are not scary, that there's no magic involved, and that working in very constrained systems is actually very fun! You'll also learn a thing or two about getting things to run for years on a battery, try that with a web app. In this talk we'll use Mbed OS, the largest open source Real-Time Operating System for microcontrollers.

But it's not always the case that if a specific code branch is allowed to have side-effects, these should be all possible side-effects. In this short talk, we will be showcasing how you will be able to further restrict effects, granularly and even recursively, in order to limit these side-effects. An example could be an application that only needs to access data from a specific website, limited to a relative URL, and then print it to the console. These effects restrictions will be designed into the application, which will allow you to outsource development to anyone with the right skill-set, even if they have bad intentions, knowing that they will live up to 100% the design or the application will not build. --- Ramón Soto Mathiesen, is a passionate computer scientist, with talent for business, who advocates for: correctness, code quality and high standards, but always with the customer in focus.

It is one of the oldest and largest open source projects in the world, having recently celebrated it's 25th birthday. FreeBSD is used to power modern servers, desktops and embedded system and its advanced networking, storage and security features makes it the platform of choice for many of the busiest web sites and most pervasive networking and storage devices. When sending a network packet across the Internet, there is a good chance it will touch a FreeBSD system along the way. This presentation will give an overview of the FreeBSD operating system and the FreeBSD project community. We will walk through what FreeBSD is, and the community behind it. I will also talk about the various features in FreeBSD, such as jails, ZFS, networking and virtualization and some of the places where FreeBSD can be found. --- Niclas is an IT consultant based in Stockholm, Sweden, specializing in systems administration, IT operations, and IT security. He has been involved in the FreeBSD project for over a decade and has been a FreeBSD committer since 2012.

In this tutorial, we'll look in detail at user namespaces, building up a basic understanding of what a user namespace is and going on to questions such as: what does being “superuser inside a user namespace” allow you do (and what does it not allow); what is the relationship between user namespaces and other namespace types (PID, UTS, network, etc.); and what are the security implications of user namespaces? We'll also explore some simple shell commands that can be used for creating and experimenting with user namespaces in order to better understand how they work. Along the way, there will hopefully be time for a few live demos. --- Michael Kerrisk is the author of the acclaimed book, “The Linux Programming Interface” (http://man7.org/tlpi/), a guide and reference for system programming on Linux and UNIX.

Yet your project isn’t succeeding in the ways you want? Maybe you’re struggling with funding or documentation? Or you just can’t find new contributors and you’re drowning in issues and pull requests? Open Source is made up of many components and we are often better-trained in methods for writing good code, than in methods for succeeding in the other dimensions we want our project to grow. In this talk we’ll explore the different components of an Open Source project and how they work together. After this talk you’ll be well-equipped with a ideas and strategies for growing, cultivating, and nourishing your Open Source project. For your project to succeed, all of its non-code components must be well-maintained. What are these different components and what methods can we learn to maintain them? - Build real relationships with your sponsors and determine ways how both sides can benefit from this relationship, don’t just ask people for money. - Establish a good communication system with your contributors: Keep them informed, listen to their feedback and input, make them feel heard. - Thank the people who worked on ticket triage or marketing, not just those who wrote code, in your release notes. - Make it easy for new contributors to get started: Write and maintain good documentation, answer questions in a friendly and timely manner. - Market and evangelize in the right places and at the right time: Give conference talks, organize sprints, keep your project’s Twitter account active, always curate new and interesting content on your blog or website. - Implement a Code of Conduct and enforce it if needed: Make your project a safe space to contribute for everyone. With these methods and a half-dozen others, you’ll handle beautifully all the components your project needs to succeed. --- Anna loves working at the intersection of tech and people and currently works for Elastic in developer relations.

The project started to continuously run functional tests on TS kernels. Tests that gets run are kselftest, ltp, and libhugetlbfs. Running tests on actual hardware isn’t as easy as you may think. Failing tests, hanging tests or flaky tests are some of the issues. The project that was going to run tests on real hardware is called Linux Kernel Functional Testing (LKFT). LKFT uses infrastructure software like Jenkins, LAVA, SQUAD and bugzilla for building, testing, displaying and tracking regressions of the LTS, mainline and next kernels. LKFT was created in early summer 2017, and the project has helped to enable LTS kernels being supported for 6 years. KernelCI is also used to build and boot testing, and today kernelCI also implements functional tests. --- Anders hates running tests and therefore he loves automating them. He has been working with Linux kernels for telecommunication (e.g. base stations, media gateways) as well as various drivers and RTOS’s for automotive systems (e.g. engine-, gearbox-platforms).

This presentation offers a graded list of things you can do to reduce boot time. They start with simple changes, such as adjusting the position of your main application the init sequence. Then there are the changes you can make to the kernel and bootloader configuration to speed things up, and finally, there are moderately advanced techniques such as using U-Boot in falcon mode. All of this is done using standard configuration techniques, with the idea of being able to maintain these changes in the future. I will show the effect of each of these changes on typical a embedded dev board so that you can judge for yourself where on the journey you want to jump off. --- Chris Simmonds is a software consultant and trainer living in southern England. He has spent almost two decades designing and building open-source embedded systems of all shapes and sizes, and he has encapsulated much of that experience in his book, “Mastering Embedded Linux Programming”.

There are several reasons why this could make sense, three common ones are: Security, Robustness and Dependency Separation. GPU access restricted to a single process requires an efficient framework for communication over IPC from the other processes, and most likely a framework for composition of surfaces. This talk describes both the possible motivations for this kind of architecture and Chromium's solution for the IPC framework. We will demonstrate how a multiprocess program can compose into a single window on Linux. --- Patricia Aas is a C++ programmer working on the Vivaldi Browser where she has currently taken on platform integration of media. She has previously worked at Opera Software on their Desktop Browser and at Cisco on their Telepresence Hardware Endpoints, primarily on Linux.

Typically PRs are used as a means to communicate that some body of work has been done and is ready to be merged. But is this an optimal use of PRs? If we submit a PR after the work has been completed, have we missed a golden opportunity to collaborate? PRs should be treated like the basic unit of collaboration within GitHub-based projects. By using PRs as communication medium and not simply as a review mechanism, we can create opportunities to communicate better within our projects, enhance the on-boarding of new contributors and help catch potential problems early. In this short talk, I show off the good, the bad and the ugly of PRs and provide a template for best practice which encourages communication and collaboration within your community. --- Paul Adams is the Open Source Lead for Europe's largest e-commerce platform, Zalando.

But the hardware lacked open source drivers and Linux support in general. The OpenHMD project was created to solve this issue, and as it so happen it was funded by two former Chalmers students. The consumer VR space has now grown from a crazy inventor in a garage into a large industry. But this growth has its down sides, multiple companies have their own APIs competing. Luckily these companies have agreed to work on a single API under the Khronos umbrella In this talk, Jakob will cover Khronos' OpenXR standard, give an overview about the current state of open source VR and what lies ahead. --- Jakob is a former student of Chalmers now working for Collabora with graphics and virtual reality.

Bring it back to RUN in modern systems ? This is a completly different history. Not talking on a full refactoring, or a port of the software, but bring s the real software with none to minor modifications. There's plenty of reasons to do that, from historical software archeology to real requirements on closed software companies that need to at least access some proprietary format to export for a different used one.

The recent addition of DRM Atomic Modesetting and Explicit Synchronization to the kernel paved the way, albeit some changes to the Android userspace were necessary. The Android graphics stack is built on a abstraction layer, thus drm_hwcomposer - a component to connect this abstraction layer to the mainline DRM API - was created.

Why? A deep-rooted survival instinct told these people that the discovery by CERN scientists of a fundamental component of our universe was something worth paying attention to. Or they were just news junkies. But, they were right. Today, at CERN, and other physics laboratories around the world, we are seeking answers to the most fundamental questions of humankind: What are we made of? Where did we come from? Where are we going? What are the rules behind all this? Although we might never find the answers, the pursuit of them provides us with the knowledge and skills our children need to survive.

A number of these projects are open source, seemingly, counteracting the funding process. We interviewed founders, developers and managers of 13 crowdfunding initiatives involving open source products to determine how communities, crowdfunding campaigns and open source are associated. Our findings verified the existence of common characteristics among the cases, the emergence of a family-like relationship between the organizers and the community, as well as the community perceived as a success factor. We suggest that the development of certain niche products inherently leads to the adoption of open source as a licensing model and crowdfunding as the capital gathering process. --- Patricia is a MSc student in the Digital Leadership program of Gothenburg University.

Luckily for us that time is over and the community around this topic has grown over last couple years and still is growing as the demand increases with the IoT revolution and OTA firmware updates (which introduces even more complexity). There are now well established open-source solutions that have been "battle tested" that we can collaborate on to make the complexity of software updates manageable. We are heading for a time where a quality Board Support Package should provide an software update implementation because it really should be solved at this level instead of handing this over to application developers which have limited knowledge of low lever architecture on a embedded device. In this talk Mirza will present some of the challenges of doing software updates on embedded system. He will also present the available open-source projects that help with solving these challenges. The projects are: SWupdate, Mender, RAUC, aktualizr (libostree) and resin.io. He will also do a head-to-head comparison of them. There is no "one fits all" solution and each one has different goals and approaches to solving the problem. This is something that we have come accustom to in the open-source community and is how we thrive. --- Mirza Krak is an embedded Linux developer with over six years of experience in the field and is currently employed by Endian Technologies AB, where he works as a consultant helping companies to deploy embedded Linux devices. He is involved in various open-source projects and is a Linux kernel contributor.

Improving software review and QA with diffoscope - Chris LambIn an age increasingly concerned with reducing bugs as well as complying with free software licenses, it is vitally important to thoroughly review audit any changes to the software that powers our technology and infrastructure. However, existing tools to perform comparisons between two versions of a software package are overly-blunt instruments, either providing too much output or none at all. Binaries such as firmware images or precompiled executables are especially problematic: a single change in the source is presented as a meaningless stream of changes, offering no insight into potentially critical bugs. And these are often precisely the files we care most about…! Diffoscope is different. Developed as part of the Reproducible Builds effort, it gets to the bottom of what makes files truly different. It recursively unpacks archives of all kinds and transforms various formats into human-readable forms for display. It can compare two tarballs, ISO images, PDFs, Microsoft Word documents, etc. just as easily. This talk explains the varied and practical usages of diffoscope and how this flexible "diff on steroids" is a long-overdue and fun tool for anyone writing or releasing software today. --- Freelance programmer, Debian Project Leader. http://foss-north.se/2018/speakers-and-talks.html#clambhttps://conf.tube/videos/embed/2f5b922a-191c-4efc-b0af-f02a3846e8bchttps://conf.tube/w/6VSUCGAqLZ64cSgS3taygqhttps://conf.tube/lazy-static/thumbnails/30037c67-1117-424e-83c1-9fc9f9c30956.jpgSpeculo: shared memory made easy - Alberto MardeganHow you can implement a lockless inter-process communication (IPC) mechanism on top of shared memory and nothing else. The talk will cover the details of how the speculo library handles its shared memory areas and how a stream of messages can be implemented on shared memory.

Later, a multitasking kernel named MiNT was adopted by Atari, and finally released as Free Software under the name FreeMiNT. GCC was ported to FreeMiNT and allowed to compile many other GNU software for the Atari platform. Emulators appeared in the '90s. As Atari TOS is still non-Free, independent developers created EmuTOS: a Free TOS clone based on open-sourced components. GCC was later upgraded to newer versions, and ready-to-use binaries of the cross-compiler were made available for Ubuntu, Cygwin, and more. This brought a new impulse to the platform. EmuTOS and FreeMiNT are still actively developed nowadays. They have been improved over the ages, and extended to support special features of emulators as well as extra hardware. They even support non-Atari hardware, such as Amiga and ColdFire processor. Moreover, development environment has been modernized to use GitHub facilities and Travis CI for automatic builds. This is a good example to see how modern tools can advantageously be used for development on old platforms. --- Vincent Rivière has always loved computers, and the Atari ST was his first own one in 1992. He learned a lot on that machine, specially assembly language and operating system internals. Then he studied Unix and Windows development in C/C++. He worked as software engineer in several companies. Later, he became interested in cross-development, and came back to the Atari ST as training target. He ported old GCC patches to newer compiler versions, and that was the starting point of new adventures with contemporary Atari communities. Especially, he was the project manager of EmuTOS between 2010 and 2015. EmuTOS is a Free operating system compatible with the original Atari one. Combined to the FreeMiNT multitasking kernel, it extends Atari-like operating systems to unsuspected levels, such as support for GNU/Linux software and exotic hardware.

Monitoring all of these might require one monitoring tool per platform, or at least a few to seamlessly blend metrics, events and logs to get true Observability on your environment. OP5's intention is to address this with Project Omega. Designed from the ground up using cloud-native technologies packaged in a container environment to be running on premise or as SaaS, scaling horizontally with Kubernetes. Initially the focus is on monitoring OpenStack with the Monasca project and developing the agent in and for the community providing patches and reviews since the Queens release of OpenStack, using modern REST API’s, time series database for metrics, message queues using Kafka and preparing the stack to for real-time analysis using Apache Storm. --- Nicolas Seyvet is a passionate software developer at OP5 AB.

Alliance of Open Media's first codec, AV1 breaks this stereotype by actually pooling *contributors*, as it consolidates the best parts, ideas and developer talent of Google's AV9/AV10, Cisco's Thor and Xiph's Daala codecs into a royalty-free and open source video codec that's not only supported by several other industry giants like Microsoft, Netflix and Apple, but is set to even beat the top-of-the-line (and patent-encumbered) HEVC codec in compression ratio. Mozilla Research has been a contributor to the development of Daala for years now and as AV1 shapes up to be the open and free codec the Internet always deserved (and one Mozilla has been fighting for) the Emerging Technologies division have further upped the stakes. As developing a cutting-edge codec requires cutting-edge technologies, Mozilla's ET division has been working on various, distributed browser-based tools to ease collaboration and hasten the solidification of such a diverse codebase. In the talk I will introduce AV1, what industry dynamics contributed to its inception and how Mozilla has developed and employed several, in-browser tools, incorporating bleeding-edge technologies like Emscripten-compiled library modules in ASM.js and WebAssembly to help the contributors iterate and bugfix newer versions of the bitstream itself, as well as the encoder and decoder. --- István Szmozsánszky (or Flaki, for short) is a web developer and trainer from Budapest, Hungary. He teaches JavaScript and frontend development, at his consulting company Skylark he helps clients build cutting-edge web application and he works with Mozilla's Developer Relations team on promoting modern web technologies.

Do you often feel like all you need is a solid starting point? If you want to see a few handy things that will be usable to you directly when you get back to work, then this is the talk for you. Of course Agile is more a way of thinking than it is a particular tool or practice, but sometimes you simply have a problem you need to solve and getting a starting point will make a big difference. That is the purpose of this talk and the book it is based on: https://leanpub.com/actionableagiletools/ . Most of these tools are very simple and can be implemented in less time than it takes to hear about them. Many of these tools were developed incrementally within teams I worked with, some literally taking years and exposure to a variety of organisations to reach their current state. -- Jeff is an Agile Coach who considers the discovery of Agile and Lean to be one of the most defining moments of his life, and considers helping others to improve their working life not to simply be a job, but a social responsibility.

The motivation behind "reproducible" builds is to allow verification that no flaws have been introduced during this compilation process by promising identical binary packages are always generated from a given source. This prevents against the installation of backdoor-introducing malware on developers' machines - an attacker would need to simultaneously infect or blackmail all developers attempting to reproduce the build. This talk will focus heavily on how exactly software can fail to be reproducible, the tools, tests and specifications we have written to fix and diagnose issues, as well as the many amusing "fails" in upstream's code that have been unearthed by this process.

Most of the people building open source software are engineers with major turn on for features and more features which kind of explains how a lot of open source projects have rich and extremely important features but are a pain to see or work with. This talk aims to deal with this problem of designing in the open which is often neglected. Tools like GitHub, GitLab, etc. can actually become an arena for usability testing and give extremely promising output only if it follows an effective design process. This talk is also a practical guide for budding designers to get started with open source software. -- Ragy Nayyar, 23, is a post graduate student in Interaction Design at KTH, Stockholm. Prior to this he has worked, both as a designer and a developer for both big companies and startups for around 2 years. He has been a contributor to open source since he started writing code and majority of my contributions are related to front-end programming and user experience decisions. He started contributing to ownCloud when they were not even on GitHub, but on Gitorious and now its one of the highest contributed PHP project on Github.

One thing most people associate the cloud with is: that vague, amorphous place where your data goes after you've captured it with your phone, laptop or fancy IoT device. That place is invariably not under your control - it is how the tech giants provide 'value' (and keep you locked in). It is also the place from where your data leaks, in high profile hacks or direct attacks from, presumably, Russians, or Chinese. Well, and Germans and Italians and everything else, both criminal and, more outrageous, government sanctioned. Nextcloud's ambition is to give you a chance to take it back, that stuff from the cloud. Control it, decide where it is and who has access. And we've built an ecosystem around our web server and apps that helps you do that. You can store and sync your files, calendar and contacts. Share holiday pictures. Listen to music. Keep your passwords secure. Edit documents, with others, collaboratively. Have video calls. All that, and more! Just not yet coffee. But you can get involved and make it happen... And obviously, when you claim to be the future, you have to address the elephant in the room: the past. So I'll talk about why and how we left ownCloud, the project we ourselves started. -- Jos Poortvliet has been marketing and promoting in communities for over a decade, active in KDE and working as community manager for SUSE and ownCloud.

He occasionally shares some of his thoughts on his blog. http://foss-north.se/talks.html#poortvliethttps://conf.tube/videos/embed/cc0ed27b-e9be-4e8b-85fa-a5e416eb9a4fhttps://conf.tube/w/skgDFyiYvLiUxJ3RYWqFGjhttps://conf.tube/lazy-static/thumbnails/d53e6199-d9f4-48f9-b09d-f1f02064e8fe.jpgOpen Source Silicon : Where software ends and hardware begins - Olof KindgrenFree and Open Source Software has since long proven to be a massive success in many areas, and the same can be said about Open source hardware over the last decade. But what about the chips themselves that are placed on circuit boards by hardware developers and programmed by software developers? This is where the Free and Open Source Silicon (FOSSi) movement comes in. Driven by the same forces as open source software - cost, curiousity, availability, security, flexibility - the FOSSi movement is about using Open Source code and tools to build the chips themselves that are at the heart of most electronic devices. This is hardly a new movement, and the roots can be traced back 20 years from the early days of OpenRISC and OpenCores, but in the last few years there has been an explosion of new projects and technologies coming from industry, academia and hobbyists. The boundaries between hardware and software are dissolving and and we're beginning to see whole new fields open up. This also means that there is an increasing number of software engineers entering the digital design domain, bringing best practices such as CI, modern languages and package dependency handling from the software world. Despite all the recent advances, the world of Open Source Silicon is still unknown even to many people working close to hardware. This presentation will give an overview of the events leading up to the current state of FOSSi. We will look at what lies ahead, both in regards of challenges and opportunitiies, and by taking a quick dive into some of the most promising projects such as RISC-V, LibreCores, FuseSoC and yosys to see how and why they can be used instead of proprietary technologies. -- Olof Kindgren is a co-founder and director of the FOSSi Foundation. Starting out with open source software in the 90's, he later became an active contributor to many different FOSSi projects such as OpenRISC and FuseSoC, and writes about this on his blog. http://foss-north....https://conf.tube/videos/embed/d53e6199-d9f4-48f9-b09d-f1f02064e8fehttps://conf.tube/w/bhBRhzF7iLcWKaeNegXWAqhttps://conf.tube/lazy-static/thumbnails/534d614f-5d82-499f-9463-ed18edc7c80c.jpgWhy values, motivation and team culture is what really creates innovation - Niklas LindhardtInnovation is hot! To say the least. And extremely important for Sweden in an ever increasing global competition. But what factors are truly relevant when it comes to create the right conditions for innovation? This talk will paint the picture of a softer perspective of software innovation. With a model built on research in motivation, organization and innovation, perspectives as culture, team and values are highlighted as truly crucial. His own company, CaptureInnovation, is built on this research, in a manager-free and innovative environment. Lessons learned, from four years of running an innovation-centered company without hierarchy, driven by individual motivators, are shared. -- Niklas is a 41 year M Sc från Chalmers. He has always found his energy in the people behind technology. What makes a person and a group really deliver and feel great, at the same time? In 2013 he was part in founding CaptureInnovation. A SW development company run in a new way: without managers, driven by motivation and culture, forming an innovative platform for new ideas.

Robust software updates on Embedded Linux devices is complex, and doing robust software updates over-the-air adds to the complexity. The hardships come of course from the embedded environment which differ in many ways compared to desktop or server Linux installations, where you must handle poor mobile network connectivity, sudden power-loss and never leave a device in a unusable state (brick) when doing the update OTA. There are a lot of examples that have gotten attention in media, where unstable software update solutions have caused real-life problems which could have been mitigated by a robust software solution that is able to handle the corner cases that exist in the embedded environment. In this talk Mirza Krak will present Mender, Apache 2.0 licensed end-to-end software update solution. This is a deep-dive session that will cover: – project ecosystem and community – technical insights – security insights And will of course include a mandatory demo. Mirza Krak is currently part of the Mender.io open source project to deploy OTA software updates to embedded Linux devices. He is an embedded Linux solution specialist with seven years of experience in the field with expertise in within Board Support Package development which ranges from hardware bring-up, boot-loaders, Linux kernel and build systems (Yocto/OE-core). Mirza was an Mender community member for a couple of years which led to an employment in 2018 to continue to work on the Mender project full-time. Mirza has spoken at various conferences including Embedded Linux Conference and foss-north.https://conf.tube/videos/embed/cf67e588-1f63-4d7a-8ff4-41091f2b249ahttps://conf.tube/w/cNSRq5ViaRGkgXM1Tko8wzhttps://conf.tube/lazy-static/thumbnails/5fa013cb-ed8e-4be1-9a35-de8ff3d2fae9.jpg2018-11: Reverse Engineer with x64dbgIn this talk Philip Karlsson talks about reverse engineering using the x64dbg tool. The hacking workshop starts with the MiGiC Guitar to MIDI Converter and focuses on how the free software x64dbg can be used to understand how the copy protection to MiGiC was circumvented.Shortly after the commercial release of MiGiC 1.0, the product was found cracked at one of the more known torrent pages. Since development hours were spent trying to protect the product he became curious in how the attackers broke the protection. In order to investigate this the open source debugger / disassembler x96 dbg was acquired to perform an analysis of both the cracked and uncracked binary. In the session Philip will show you parts of the analysis as well as presenting three so called ”crackmes” that you will get the opportunity to find weaknesses in using the x64dbg tool. Therefore, its a good idea to bring a PC so you can use the tool yourself.https://conf.tube/videos/embed/5fa013cb-ed8e-4be1-9a35-de8ff3d2fae9https://conf.tube/w/1XRyr6BperFmxMkmuKtoa7https://conf.tube/lazy-static/thumbnails/07cc7304-2faa-4964-a3a2-4cd4d4e90410.jpg2018-08: Lightning Talk - Att spara 15 minuterLightning talk by Jens Reuterberg.

In this presentation Anders will talk about the Podman and Kubernetes projects, and show how to run Linux containers - without using a Docker daemon. It will include a brief introduction and a historic background of container technology, as well as some demonstrations on how you can run it locally. - Linux containers are technologies that allow you to package and isolate applications with their entire runtime environment - all they need to run. Containers share the operating system (OS) kernel and therefore do not require an OS per application, requiring less resources than virtual machines. - Kubernetes (k8s) is an open-source container orchestration system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery, and was originally released by Google in 2014. Anders Björklund is a system developer working with continuous integration and continuous delivery using distributed build systems based on Linux. He has been working with Linux and containers for a long time, and is part of the Docker Machine community and a maintainer of Kubernetes Minikube.https://conf.tube/videos/embed/6813071b-9259-4675-a673-b24684bc20ddhttps://conf.tube/w/rkLzhDywrCKieb7FQ1q2E5https://conf.tube/lazy-static/thumbnails/cd37115a-0e93-4f14-b9ed-173348aae244.jpgEncrypting at the Source - Protection from Creation - ZifraIn many parts of the world, journalists and human rights activists have their equipment seized or checked by oppressive forces. The information carried by these individuals can be compromising to themselves and their sources. Nowadays, nothing is done to protect this information before it reaches a safe environment, so anyone with a physical access to the journalists' cameras and memory cards can see their content. The team from Zifra will introduce their encrypting memory card and present how it can solve the challenges of journalists and human rights activists around the world, by protecting the information from its creation. The importance of the design of the user experience and the role of the user-friendliness in information security products for non-technical users will also be discussed. -- Zifra is a Gothenburg-based startup that develops a live-encrypting memory card to protect information from the moment of its creation. http://foss-north.se/talks.html#zifrahttps://conf.tube/videos/embed/cd37115a-0e93-4f14-b9ed-173348aae244https://conf.tube/w/xvNsxXJfG5LePad4KerVMKhttps://conf.tube/lazy-static/thumbnails/ff347f97-eac2-41fa-90fa-74098fcd7029.jpgIntro to ActivityPub Conference Praha 2019 by Morgan Lemmer Webber #apconfActivityPub Conference Praha 2019 – https://redaktor.me/apconf/ A conference about the present and future of ActivityPub, the world’s leading federated social web standard.

MillerAs social systems grow, we need patterns to allow us to grow social connections while maintaining safety and trust. Ocaps (object capabilities) fill this void by allowing consensual connections between parties, and even allows participants to intentionally share those connections with others. But how can we allow for the establishing of new connections without opening us up to runaway abuse? This talk discusses Horton, a "whodunnit" layer built on top of object capabilities, allowing us to establish connections while preserving accountability and the ability to reason about trust with a reduction of fear. :: ActivityPub Conference Praha 2019 – https://redaktor.me/apconf/ A conference about the present and future of ActivityPub, the world’s leading federated social web standard.

In federated social networks, unfortunately so far the view on all posts of a hashtag is fragmented between instances. For a student research paper I came up with an architecture for search and subscription of hashtag-posts in federated social networks. This additional backend for instances augments the Fediverse with a little bit of P2P technology. As this architecture is still at a conceptual stage, after presenting my work I'd like to gather ideas and feedback from various Fediverse stakeholders: What do global hashtags mean for marginalised people and moderation, are they more a tool of empowerment or of harassment? How can this concept be represented in the ActivityPub protocol?

Privacy by default and design are core principles that are fundamental to how software should be envisioned. The GDPR that came into the spotlight has a strong case to become a standard even outside European borders, influencing the way we protect personal data. However its impact might be, its implementation is still in its infancy. OSS has found itself facing the situation and one aspect which is particularly interesting on the tech side is how to incorporate the principles of privacy by default and design into the software that we build. This talk is going to be an overview of how the GDPR has impacted FOSS communities, what do we mean by privacy by default and by design, how could we envision them applied in our OSS. It will bring examples from which we might find something interesting to learn from, regardless if we are looking at them as mistakes, best practices or just ways of doing things. :: ActivityPub Conference Praha 2019 – https://redaktor.me/apconf/ A conference about the present and future of ActivityPub, the world’s leading federated social web standard.

Perhaps the reason for this is because it's all too easy to conflate unattributed speech with unmoderated speech, which has shown itself to be a dead end. But as we've seen from Twitter and Facebook, putting a name on everything hasn't actually worked that well at improving the quality of discourse, but what it does do is put already marginalized people at greater risk. What I credit as one of the biggest breakthroughs of the fediverse has been the loose federation which allows a person to choose their moderator, completely side stepping the question of undemocratic censorship vs. toxic free speech. Now I want to start a conversation about how we might marry this powerful moderation system to a forum which divorces the expression of thought from all forms of identity. :: ActivityPub Conference Praha 2019 – https://redaktor.me/apconf/ A conference about the present and future of ActivityPub, the world’s leading federated social web standard.

The COVID-19 pandemic has brought this trend from a convenience to a necessity. [Morgan Lemmer-Webber](https://octodon.social/@mlemweb), [Sebastian Lasse](https://mastodon.social/@sl007/104814347340990754), [Thomas Markey](https://fosshost.org) In this talk, organizers of APConf will discuss how we threw together a virtual conference using Peertube and a Big Blue Button server hosted by Fosshost. Fosshost provides cloud compute power to the free and open source software community. Established hosting providers donate infrastructure to the fosshost project, which in turn they manage and share with the open source community. These reciprocated values of sharing, improve, promote and advance the use of free software. Fosshost provides hosting to more than thirty open source projects including Celestia Space, XFCE, GNOME, XIPH, the ActivityPub Conference and many more.https://conf.tube/videos/embed/87bc99dd-b1b8-4fc3-b034-dca805388179https://conf.tube/w/qdQijLPJSKH4zAVqn61iEohttps://conf.tube/lazy-static/thumbnails/c42604a8-d71d-4bd0-8081-d2c77210f206.jpgLearnAwesome.org - Building a better GoodReads with ActivityPubLearnAwesome.org is building an open-source learning map for humanity. It curates and categorizes learning resources across topics, formats and much more. It is also a social network - much like GoodReads - that's focused on learning. It implements standards like ActivityPub, RSS, LRMI schema and more. This is the video for my talk given at ActivityPub Conf 2020. Nilesh Trivedi @nilesh@fosstodon.orghttps://conf.tube/videos/embed/c42604a8-d71d-4bd0-8081-d2c77210f206https://conf.tube/w/hvfE9FWQVwNyumGejnn4P7https://conf.tube/lazy-static/thumbnails/85a7d230-7e75-48fd-b399-d182ddece030.jpgSkoHub: Supporting topic-based content syndication & discovery in a federated environment[SkoHub](https://skohub.io) implements an approach to resource discovery in a federated environment that is based on subscription and push notification instead of crawling, indexing and search. To enable this, it combines ActivityPub with SKOS (Simple Knowledge Organization Systems), a long-lived W3C standard for publishing classifications, thesauri and other controlled vocabularies on the web. The core idea is to make the terms of a Knowledge Organization Systems ActivityPub actors. Thus, people can follow topics and receive notifications about newly published resources via a topic-based channel. The initial SkoHub project has been carried out in 2019/20 by the hbz in cooperation with graphthinking GmbH. Initially, SkoHub was targeted at educators and learners who want to publish and share Open Educational Resources (OER) on the web. Traditional approaches for resource discovery of open content are usually based on archives containing published documents plus metadata. Complementary to this approach, SkoHub takes into account that educational and scholarly resources can be found all over the web and thus a web-centric approach to resource discovery is pursued. But SkoHub could also play an important role in the fediverse at large for addressing the problem of finding relevant content in a decentralized infrastructure. For example, PeerTube instances could publish their videos to a shared classification and thus be able to present to users resources from all over the fediverse, even without beforehand knowing all the other instances. Adrian Pohl, literarymachinehttps://conf.tube/videos/embed/85a7d230-7e75-48fd-b399-d182ddece030https://conf.tube/w/q2tjRoFV4vyRUPEEAyEZHqhttps://conf.tube/lazy-static/thumbnails/c28fe948-1308-4669-97a7-3c0e08500116.jpgDigital public sphere - From gated platforms to the fediverseNew advancements and evolved technologies always affected society. This talk discusses the inquiry to what extent fediverse has an influence on changes in the public sphere. In addition, this lecture will address the question of how the rising fediverse is a transition from antagonism to agonism. • Does changing from gated platforms to fediverse support a pluralistic culture? • What is the likelihood that larger instances will represent a coherent implementation in terms of standards such as ActivityPub? • How does blocking (particularly blocks between instances) impact this adjustment in public sphere? • Why do we need a specific measure of blocking and which limits do they confine? Erwin Ernst Steinhammerhttps://conf.tube/videos/embed/c28fe948-1308-4669-97a7-3c0e08500116https://conf.tube/w/6kSbzJ4LTSAY1wMYzA97Mfhttps://conf.tube/lazy-static/thumbnails/2b43c03e-b5d7-420d-b30d-fe16fda7f498.jpgUsing federated instances as discussion communitiesFrom the field of psychology, specifically cultural psychology, emphasis is placed on the construction of discussion spaces that have traditionally been seen as the physical classroom, however, since the emergence of social networks, these digital spaces have been used to try to generate communities of discussion and that later lead to learning. Unfortunately, as it is known, the most used social networks have serious privacy problems, which leads to the voluntary delivery of data to large corporations. It is for this reason that a small project has been started where the use of Mastodon is proposed for the development of online discussions on specific topics with psychology students, which could result in experiences that generate data on what elements to consider for unleash the discussion and how the participants relate in this type of scenario. Fortunately, Mastodon and its mobile applications favor the development of activities without problems for users, which could be successfully developed by a small community of psychologists.

It supports developers with different goals, from the polished projects of WriteFreely to scrappy personal blogs and a large swath of unnamed tinkered projects. Its development began in December 2017 and is still ongoing, readily scaling across new vocabularies, like ForgeFed, and is accommodating of complimentary libraries so clients can choose to embrace community-proposed solutions. Go-Fed takes to heart the philosophy that the ActivityPub specification left opportunities for further evolution of its core ideas. It also embraces the philosophy of "only solving one problem" to provide a concrete platform for experimenting with the protocol itself or experimenting with a complementary idea. This talk addresses Go-Fed’s unique history of being an early adopter, the challenges of developing in a statically-typed language, and the difficulty of rigorously isolating the "ActivityPub protocol layer" from other layers or an application. It goes over the approach to adopting the suite of libraries in new or existing codebases for interested developers. Finally, the project maintainer will provide his outlook on where Go-Fed can help provide a productive platform for protocol experiments, and where the project will focus efforts into 2021.

The core feature of XWiki is its capacity to design structured-data documents and applications directly in the wiki. But if XWiki is easily extensible and has a store of more than 900 existing extensions, until recently its social features were limited inside the platform and didn’t allow to interact outside it, in a federated ecosystem.

Reflections on a 20 year tradition of re-inventing the wheel.From UseNet to ActivityPub, every protocol solves the same problems over again. - How do we discover nodes? - How do we deal with network partitions? - How do we define bad behavior and how do we prevent it? The algorithms which solve these problems are present in almost every decentralized protocol. They are also famous for being very difficult to get right! In this lecture I will to propose an alternative. Why can’t we let the database do the replication and stick to writing the rules? When a node is a finite state automaton, all we need is an SQL-like language to define the set of all legal state transitions.https://conf.tube/videos/embed/ccad21f7-6bc7-489e-886f-ba0fb8d20647https://conf.tube/w/43DMctGZywCLYieNfTts9Shttps://conf.tube/lazy-static/thumbnails/18aa2f92-36cc-4424-9a4f-6f2de946fbd2.jpgSpritely and Federation Futures[Spritely](https://spritelyproject.org) is a laboratory-project to incubate tools for the future of the fediverse, working on such things as Goblins (distributed programming), Porta-Bella (Distributed Storage), improved security for user interface designs, etc. See live updates and demonstrations from the Spritely project and hear how these incubated technologies could help pave positive futures for the fediverse.https://conf.tube/videos/embed/18aa2f92-36cc-4424-9a4f-6f2de946fbd2https://conf.tube/w/jqTdss1qrdk4yEZiQsnMU3https://conf.tube/lazy-static/thumbnails/953de898-74dc-4665-95fb-313042f66cc6.jpgThe reboot of the indymedia projectWe are a wide affinity group working to reboot the global indymedia network using modern federated protocols such as #activitypub.

If we want to do the latter, we need to identify the fundamental assumptions that constrain the giants and ask ourselves what we can do when we throw those assumptions out entirely. In this talk, I am going to try and inspire you to make things that would be literally impossible to make on the centralized web. I am going to talk about both the advantages and disadvantages of doing this kind of thing. Expect to hear concrete examples of software that already exists, and also examples of software that could conceivably exist in the very near future.

Almost immediately, Gab was met by a dedicated movement to isolate it. The movement was largely successful; within a year, the Gab CTO announced they would leave the Fediverse. This talk will cover how moderators, activists, and developers in the Fediverse used human moderators, strong moderation tools, representative codes of conduct, and no small amount of organization to promote healthy online spaces. We’ll review how some of the challenges faced by centralized platforms, which struggle with their own size and scale, have been addressed in networks of smaller, community run, more moderated servers. In the debate over how to make a healthier internet, the open platforms and open protocols in the model of the Fediverse may have some of the best resources to isolate bad actors, including Gab. Derek Caelin is an Innovation and Data Specialist at Counterpart International (CPI) with experience in open source technology and social media. He has helped activists deploy technology for social good at CPI, PeaceTech Lab, and the United States Institute of Peace. In writing this article, Derek spoke with 80 people, primarily on Mastodon, including 12 interviews of Fediverse administrators and moderators as well as hate speech monitors and experts in dangerous speech. He also conducted a survey of Fediverse users with 670 respondents.

It will consider best practice recommendations and the specific characteristics of decentralized models. For example, data separation is one of the main privacy design principles. Thus, a decentralized model is preferable as opposed to a centralized one. If we were to imagine a privacy by design future, a social media platform would be decentralized. Unfortunately, data separation alone is not contouring this future. What design principles are there to consider? What are the particular challenges posed by decentralized systems? This talk will tackle these topics and propose ways in which we can address them.https://conf.tube/videos/embed/a0196813-fb0d-4740-a37a-5f2b1fd1e774https://conf.tube/w/stJEcv4PqrkDMZowB7g6wbhttps://conf.tube/lazy-static/thumbnails/d66cf9ea-e8bf-452e-bb36-e88a402e3da2.jpgCommonsPub and the quest for a modular decentralised app ecosystemThe goal: empower people to create and self-manage social spaces and tools tailored to their needs. ActivityPub gave us interoperability at the data level, and we’d like to do the same on the software level with CommonsPub. Instead of a top-down “product design” approach to building an app or platform, we’d like a world where even non-technical users and communities can do it themselves: being able to piece together custom experiences from an ecosystem of apps and plugins developed by different groups who all contribute to (and benefit from) a pool of interdependent software libraries, while each focusing on different use cases, features and user experiences. We have implemented groups (to further decentralise the fediverse by rendering users and communities independent from the instance they’re on), and decoupled the federation and storage of ActivityStreams activities/objects from the app’s relational database, backend logic, APIs and frontend interfaces. This means users can have one fediverse identity and a timeline which shows all types of content and activities in one place, while participating in multiple communities and using specialised apps for different activities.

We are currently building a generic UI supporting the entirety of the client portion of the client to server protocol. In a CMS world no information should be hidden by the UI but it must be well-arranged. Let's talk and about how we can build conformance, generic servers and patterns for diverse clients together! This piece will identify repeating problems and misconceptions from socialhub and explore • what the concept of a generic ActivityPub conformant server means • how the client to server protocol helps us and what patterns are involved • how we can design, code and work together in perfect federated harmony Sebastian Lasse @sl007@mastodon.socialhttps://conf.tube/videos/embed/4102f53a-3f91-46c1-bb9b-fb954990f023https://conf.tube/w/qDpwcp4qkHgVYQdh9ZgTiqhttps://conf.tube/lazy-static/thumbnails/c79457a9-aae5-47dd-8731-617e6b09fe06.jpgThe ActivityPub ecosystemWe have a big world to build.

Unfortunately, as it is known, the most used social networks have serious privacy problems, which leads to the voluntary delivery of data to large corporations. It is for this reason that a small project has been started where the use of Mastodon is proposed for the development of online discussions on specific topics with psychology students, which could result in experiences that generate data on what elements to consider for unleash the discussion and how the participants relate in this type of scenario.

This type of sensor will require lower maintenance compared to traditional sensors, as well as potentially differentiate between rain and hail. The talk will focus on the technical challenges of designing and implementing such a sensor from both a hardware and software perspective. Besides the technical aspect, the talk will also address the reason the sensor is designed in the first place, namely the development of an open network of hazardous precipitation early warning systems.

This talk takes a look at three essential elements of this path: * Strategy: How can you monetize your open source product? Is it support, an open core approach, cloud services, or a combination of the three? And which ones are the features you can even commercialize without alienating your community? * Struggle: "You received a 100 million dollars in venture capital and yet you have so many open issues?!" Once money is involved the dynamics often change. How can you manage expectations? * Success: How do you balance open source and commercial success? This talk takes the perspective of Elastic, the company behind several open source projects as well as taking a look at how others are approaching this challenge, what worked, and what failed.

Wikidata is the structured data backbone of Wikipedia. While originally built to support Wikipedia, it is now used in a variety of applications from open source projects to companies' question answer systems. Similar to Wikipedia, anyone can edit the data of Wikidata. The focus of the workshop will be an introduction to Wikidata. Firstly, we will talk about Wikidata, what it looks like and its data structure. Further, I will give an introduction to how to access Wikidata's information: the APIs as well as the SPARQL endpoint which allows users to query the project. The atmosphere is supposed to be informal: if anyone already works on projects that can make use of Wikidata, please bring them along so we can discuss. If you have a general interest to include general knowledge about the world in your application, this might be the right workshop.

Even if the community has provided many drivers you can use on various system, from cheap Arduino DIY boards to full GNU/Linux boxes, the lack of unification can appear chaotic to developers. To solve fragmentation of implementations W3C proposed "Generic Sensors API" which is worth to be supported; while JavaScript is totally capable capable of addressing low end targets (using Node.js or IoT.js powered by JerryScript engine).

In the #workFromHome era digital infrastructure is as important for small & medium companies as it is having an office (remember that?). Unfortunately, over the last decade, internet infrastructure is offered by only handful companies including Google, Apple, Facebook, Amazon and Microsoft, otherwise known as GAFAM. They promote themselves as the most convenient offer for digital infra, but as some would say 'nothing comes for free'. The cost for our convenience is giving our privacy to these companies. Moving to free open source alternatives is the way to go if we want to regain digital sovereignty. Good news: there are already solid alternatives to a reality full of tech oligarchs and this is what this presentation is all about. In less than 30 minutes, Redon will showcase the smooth transition process that SMEs can have while using free open source instances such as Nectcloud, Discourse, Bitwarden and BigBlueButton to mention a few.

Almost immediately, Gab was met by a dedicated movement to isolate it. The movement was largely successful; within a year, the Gab CTO announced they would leave the Fediverse. This talk will cover how moderators, activists, and developers in the Fediverse used human moderators, strong moderation tools, representative codes of conduct, and no small amount of organization to promote healthy online spaces. We’ll review how some of the challenges faced by centralized platforms, which struggle with their own size and scale, have been addressed in networks of smaller, community run, more moderated servers. In the debate over how to make a healthier internet, the open platforms and open protocols in the model of the Fediverse may have some of the best resources to isolate bad actors, including Gab. Derek Caelin is an Innovation and Data Specialist at Counterpart International (CPI) with experience in open source technology and social media. He has helped activists deploy technology for social good at CPI, PeaceTech Lab, and the United States Institute of Peace. In writing this article, Derek spoke with 80 people, primarily on Mastodon, including 12 interviews of Fediverse administrators and moderators as well as hate speech monitors and experts in dangerous speech. He also conducted a survey of Fediverse users with 670 respondents.

ActivityPub gave us interoperability at the data level, and we’d like to do the same on the software level with CommonsPub. Instead of a top-down “product design” approach to building an app or platform, we’d like a world where even non-technical users and communities can do it themselves: being able to piece together custom experiences from an ecosystem of apps and plugins developed by different groups who all contribute to (and benefit from) a pool of interdependent software libraries, while each focusing on different use cases, features and user experiences. We have implemented groups (to further decentralise the fediverse by rendering users and communities independent from the instance they’re on), and decoupled the federation and storage of ActivityStreams activities/objects from the app’s relational database, backend logic, APIs and frontend interfaces. This means users can have one fediverse identity and a timeline which shows all types of content and activities in one place, while participating in multiple communities and using specialised apps for different activities.

This reboot will be based on the OMN project code. What is the OMN (Open Media Network): The project is to shift power to the producers and consumers of media. It’s about good UI and simple empowering #KISS tools to move content, by categorising it with a grassroots folksonomy. This simple approach is balanced by shared site level syntax for the complex crew. In the end it’s about bringing trust back into news.

Unfortunately, as it is known, the most used social networks have serious privacy problems, which leads to the voluntary delivery of data to large corporations. It is for this reason that a small project has been started where the use of Mastodon is proposed for the development of online discussions on specific topics with psychology students, which could result in experiences that generate data on what elements to consider for unleash the discussion and how the participants relate in this type of scenario. Fortunately, Mastodon and its mobile applications favor the development of activities without problems for users, which could be successfully developed by a small community of psychologists.

This talk discusses the inquiry to what extent fediverse has an influence on changes in the public sphere. In addition, this lecture will address the question of how the rising fediverse is a transition from antagonism to agonism. • Does changing from gated platforms to fediverse support a pluralistic culture? • What is the likelihood that larger instances will represent a coherent implementation in terms of standards such as ActivityPub? • How does blocking (particularly blocks between instances) impact this adjustment in public sphere? • Why do we need a specific measure of blocking and which limits do they confine?

The core feature of XWiki is its capacity to design structured-data documents and applications directly in the wiki. But if XWiki is easily extensible and has a store of more than 900 existing extensions, until recently its social features were limited inside the platform and didn’t allow to interact outside it, in a federated ecosystem.

It supports developers with different goals, from the polished projects of WriteFreely to scrappy personal blogs and a large swath of unnamed tinkered projects. Its development began in December 2017 and is still ongoing, readily scaling across new vocabularies, like ForgeFed, and is accommodating of complimentary libraries so clients can choose to embrace community-proposed solutions. Go-Fed takes to heart the philosophy that the ActivityPub specification left opportunities for further evolution of its core ideas. It also embraces the philosophy of "only solving one problem" to provide a concrete platform for experimenting with the protocol itself or experimenting with a complementary idea. This talk addresses Go-Fed’s unique history of being an early adopter, the challenges of developing in a statically-typed language, and the difficulty of rigorously isolating the "ActivityPub protocol layer" from other layers or an application. It goes over the approach to adopting the suite of libraries in new or existing codebases for interested developers. Finally, the project maintainer will provide his outlook on where Go-Fed can help provide a productive platform for protocol experiments, and where the project will focus efforts into 2021.

The algorithms which solve these problems are present in almost every decentralized protocol. They are also famous for being very difficult to get right! In this lecture I will to propose an alternative. Why can’t we let the database do the replication and stick to writing the rules? When a node is a finite state automaton, all we need is an SQL-like language to define the set of all legal state transitions.

To enable this, it combines ActivityPub with SKOS (Simple Knowledge Organization Systems), a long-lived W3C standard for publishing classifications, thesauri and other controlled vocabularies on the web. The core idea is to make the terms of a Knowledge Organization Systems ActivityPub actors. Thus, people can follow topics and receive notifications about newly published resources via a topic-based channel. The initial SkoHub project has been carried out in 2019/20 by the hbz in cooperation with graphthinking GmbH. Initially, SkoHub was targeted at educators and learners who want to publish and share Open Educational Resources (OER) on the web. Traditional approaches for resource discovery of open content are usually based on archives containing published documents plus metadata. Complementary to this approach, SkoHub takes into account that educational and scholarly resources can be found all over the web and thus a web-centric approach to resource discovery is pursued. But SkoHub could also play an important role in the fediverse at large for addressing the problem of finding relevant content in a decentralized infrastructure. For example, PeerTube instances could publish their videos to a shared classification and thus be able to present to users resources from all over the fediverse, even without beforehand knowing all the other instances.

It will consider best practice recommendations and the specific characteristics of decentralized models. For example, data separation is one of the main privacy design principles. Thus, a decentralized model is preferable as opposed to a centralized one. If we were to imagine a privacy by design future, a social media platform would be decentralized. Unfortunately, data separation alone is not contouring this future. What design principles are there to consider? What are the particular challenges posed by decentralized systems? This talk will tackle these topics and propose ways in which we can address them.

The COVID-19 pandemic has brought this trend from a convenience to a necessity. In this talk, organizers of APConf will discuss how we threw together a virtual conference using Peertube and a Big Blue Button server hosted by Fosshost. Fosshost provides cloud compute power to the free and open source software community. Established hosting providers donate infrastructure to the fosshost project, which in turn they manage and share with the open source community. These reciprocated values of sharing, improve, promote and advance the use of free software. Fosshost provides hosting to more than thirty open source projects including Celestia Space, XFCE, GNOME, XIPH, the ActivityPub Conference and many more.

If we want to do the latter, we need to identify the fundamental assumptions that constrain the giants and ask ourselves what we can do when we throw those assumptions out entirely. In this talk, I am going to try and inspire you to make things that would be literally impossible to make on the centralized web. I am going to talk about both the advantages and disadvantages of doing this kind of thing. Expect to hear concrete examples of software that already exists, and also examples of software that could conceivably exist in the very near future.

It is also one of the most fundamental concepts to understand in order to produce coherent, stable, and efficient systems and containers, especially at scale. In this talk, we will go over how to compose reliable memory heavy, multi container systems that can withstand production incidents, and go over examples of how Facebook is achieving this in production at the cutting edge. We'll also go over the open-source technologies we're building to make this work at scale in a density that has never been achieved before. We'll also discuss widely-misunderstood Linux memory management concepts which are important to site reliability and container management with an engineer who works on the Linux kernel's memory subsystem, busting commonly held misconceptions about things like swap and memory constraints, and giving advice on key and bleeding-edge kernel concepts like PSI, cgroup v2, memory protection, and other important container-related topics along the way.

Matrix is an [open standard](https://matrix.org/) for interoperable, secure and decentralised, real-time communication over the Internet. It can be used to power Instant Messaging, VoIP/WebRTC signaling, Internet of Things communication - or anywhere you need a standard HTTP API for publishing and subscribing to data whilst tracking the conversation history. By self-hosting Matrix you begin to take control of your own data and your own communications. You also get to join an ever-growing federated network of over 40,000 servers, totaling over 18M users. In this talk, I'll show you how to install Synapse, the reference Matrix server implementation, so you too can enter the Matrix.

How many services and servers are there, and how does it even all fit together? Also, what do we have planned for the future and how can you help? Find out in this talk! Arch Linux is a complex open-source project with many moving parts, quite a few pieces of infrastructure, and many people involved. Arch uses some modern DevOps tools like Ansible and Terraform. All of our infrastructure is entirely in the open (except for where is unreasonable to do so). While we do try to follow the general Arch dogma of keeping things simple, this sometimes conflicts with doing things _right_ and maintainable. We're mostly hosted at Hetzner with a few sponsored servers for non-critical and non-trusted services. Among our public services are: - Accounts/SSO - AUR - BBS - Bug tracker - GitLab - Mailing lists - Main page and package list - Mirror list - Patchwork - Security tracker - Wiki Next to these public services, we also operate quite a few staff-only services such as: - Build servers - Kanboard - Mail servers - Monitoring stack: Grafana, Prometheus, Alertmanager - Phrik - Quassel Our servers and services used to be hand-configured without any audit trail. In the past years, we've started the effort of formalising all services we operate using Ansible and Terraform which has been very helpful. ### Ongoing efforts While there have always been minor efforts here and there for various tasks, in recent times we've seen some increased activity especially in these topics: - Automation: Many parts in Arch have always been done manually.

Now that the distribution has reached adulthood, it is a good time to reflect on its history, the decisions that have made it the distribution it is today, and what lessons we have learned along the way. We will conclude with a discussion of the future of the distribution, what we are currently working towards and the possibilities to come.

With the enhancement and stabality of the TICK stack in 2020, let us see if custom kernels on a minimal distribution (Arch Linux) on an edge computing device really shines. Custom kernels, such as the Linux RT Kernel as well as the Xanmod boast a kernel-level preemption which are supposed to make them better at real time tasks. We have seen a lot of applications of this, such as machines with real time kernels go into space. Let us see how an edge computing device running Arch Linux on a custom kernel fairs any better in 2020.

This will give an overview of what has changed recently and what you can expect from your install medium in the future. Since its inception (somewhere back in 2006) different developers have been taking care of archiso as the in-house project to create installation media for Arch Linux. It gained various features over the years, while serving the i686 and x86_64 architectures. Although development of the tool has slowed down due to available time and/ or interest, 2020 has seen a lot of changes and more are yet to come. We will look at the following topics (among others): * move to gitlab * various outstanding fixes * code refactoring and cleanup * linting and initial implementation on automated testing * additional scripts * license change * move towards an easier configuration through templates Additionally, the road towards a complete automation of the installation media release and a few new features such as accessibility and reproducibility will be discussed.

In my work on distri, I show that package managers can fill almost any line rate (1 Gbps, 10 Gbps, 100 Gbps) effortlessly with the right architecture. In this talk, I will explain the key ideas in distri’s architecture, and what impact they have on the resulting system. For example, packages are distributed as SquashFS images in distri, which makes their contents immutable and the overall system harder to break.

I am looking for standard-compliant technologies which are cloud-first and end-to-end encrypted. That is, if I lose a device of mine, I do not lose any piece of valuable data, and neither can anyone else access it. I have been experimenting with many FOSS alternatives to traditionally centralised systems, such as timetabling, tasks, personal archiving, emails, password managers. In this talk I will present my top picks for FOSS projects which get the job done. I will put a particular focus on personal file management - efficient folder structures, cloud syncing, encryption, and cached access. Lastly, I will direct attention to killer features which you can contribute to and advance this field massively :) Zvezdin Besarabov https://pretalx.com/arch-conf-online-2020/talk/HFUDJZ/https://conf.tube/videos/embed/5e2c59d8-c6d8-495e-9a51-e5cf2f25705ehttps://conf.tube/w/sjhjByKQc5GAmkV3GdgDjxhttps://conf.tube/lazy-static/thumbnails/d51b0d17-a773-4f17-85c8-91c5b1dfcc7f.jpgArch Conf 2020 - Rolling your own security team for fun and no profit at allhttps://media.ccc.de/v/arch-conf-online-2020-6394-rolling-your-own-security-team-for-fun-and-no-profit-at-all A deep dive into the Arch Linux Security Team from day zero up until today.

In this session I will demo WYSIWYG editors written with widgets and with Qt Quick. Since I started using computers in the 1980's, there's always been a frustrating gap between wysiwyg word processors and text editors: you could have some sort of formatting, or you could save a plain text file that's easy to read in myriad other ways; but usually not both. I added markdown support to Qt to bridge that gap (without using HTML conversion at any stage). Now I can use a wysiwyg editor and save markdown-formatted text that looks as good or better than what I could write by hand. It's the universal format for note-taking, journaling, todo lists, writing emails, blogging and other types of simple publishing. Qt supports most of the advanced markdown features too: notably tables and checklists. I even have an editor that uses a KIO slave to directly publish markdown on IPFS for easy sharing.https://conf.tube/videos/embed/ed859eed-d658-4495-94e0-72ce2145b77bhttps://conf.tube/w/oP6B1iNktVbDSy1dgt35johttps://conf.tube/lazy-static/thumbnails/b8bc7604-fde7-4b1a-9cf5-dc6dfc35851a.jpgHow to Create a Good Promotional Website for your Project - Akademy 2020Having a good website for your project should be a fundamental part of your application promotion. This is not an easy task, and in this task I will explain how to make it easier for you to get it right. I will present the KDE Jekyll theme, the motivation behind this project, and briefly explain how it can be used to create a KDE website.

I will talk about the API changes in QInputEvent and its subclasses, what it means for Qt Quick, and do a demo of some new features that the new event delivery architecture enables. More details about the goals in Qt 6: - every QInputEvent should carry a pointer to an object representing the device it came from, with more details than we had before, to enable the recipients to handle it intelligently - Qt Quick items (and especially Input Handlers) should mostly keep working as they already do - Widgets will keep working as they already do - QPointerEvent will be introduced, with common API for mouse, touch and tablet events; that will hopefully enable more unified delivery code rather than duplicated code for different event types, and also less reliance on mouse emulation - Qt Quick can go back to delivering the original QPointerEvents rather than wrapping them - we can perhaps finally make Flickable touch-aware: because the event doesn't look that different from a mouse event anymore, we shouldn't have to duplicate much code to get Flickable to do all its filtering, delaying and replaying with touch events just as with mouse events - Wacom tablets and other pressure-sensitive stylus devices will be much better supported in Qt Quick - we hope to be in a position that we can begin to support multi-seat (multi-user) UIs https://conf.tube/videos/embed/84b4319a-14bc-4482-b231-c34388d62260https://conf.tube/w/nX1JeSbsb47iBgq3G8Dtzphttps://conf.tube/lazy-static/thumbnails/b1be449c-acba-43b1-9938-fa3be26ed815.jpgNative Desktop Styling Support for QtQuick Controls 2 - Akademy 2020At The Qt Company we have an ongoing project in the UI team to improve the support for writing desktop applications using QtQuick Controls 2. The long term goal is to bring Controls up to the same level as, or better than, Qt Widgets in terms of available controls, API, and styling. In this talk I will present which ideas we have at The Qt Company in this area for the next few years, and the initial work done for Qt-6.0 to realize it. QtQuick Controls 2 was from the start primarily written for applications in the embedded and mobile space. While it’s fully possible to write applications for the desktop as well using Controls 2, it lacks some important features that for some will make Qt Widgets the only viable alternative when targeting desktop. This includes, among other things, desktop centric controls, native menus, pop-ups and dialogs, and native styling. At The Qt Company we have laid out a five year long plan to close the gap between Controls and Widgets. And we have started this year, as an initial step, to port QStyle to Controls, and remove all dependencies to Widgets in the new port. This means that we are not touching QStyle in Widgets, but have chosen to leave it as-is, to have the freedom to change and optimize the new port, and at the same time, avoid regressions and API breakages in Widgets. We use the new QStyle port as a starting point to implement native looking desktop styles in Controls that follow the same styling API and rules that Controls already have. We are currently working on styles for macOS, Windows and Fusion, and all three will be available for Qt-6.0. In this talk I will elaborate more around our plans for the future in this area, and show a demo of the current progress.https://conf.tube/videos/embed/b1be449c-acba-43b1-9938-fa3be26ed815https://conf.tube/w/oVWPvDotBK2rs6nqUoK5HThttps://conf.tube/lazy-static/thumbnails/b9b140fb-6031-4318-b3b3-56c07cb29e25.jpgQML Rapid Prototyping - Akademy 2020QML prototyping is something that all developers do, this talk will demonstrate how can this be achieved more efficiently and friendly. Will be presented two projects, QHot (a hot reload for nested QML files) and QML Online (an online QML editor created with webassembly), both projects tries to bring down the development time and the learning curve for QML, helping the visualization and the experimental of QML snippets as fast as possible. It's a common practice to do QML prototyping, snippets to brainstorm ideas or to help newcomers that are still learning. The talk will highlight how important is for developers to create tools to help with the development time besides the development itself, besides that, will also be explain how important is the creation of such tools to be accessible, easy to use and friendly! https://conf.tube/videos/embed/b9b140fb-6031-4318-b3b3-56c07cb29e25https://conf.tube/w/hXHdERFe2U1ue2xgZW6Kkxhttps://conf.tube/lazy-static/thumbnails/89598716-1126-4e1f-8853-50202a54d481.jpgFlatpak, Flathub and KDE: A Quick Summary - Akademy 2020A quick summary of what is flatpak, what is flathub and how KDE interacts with both of them. https://conf.tube/videos/embed/89598716-1126-4e1f-8853-50202a54d481https://conf.tube/w/nv3rDxd8FGVpRKfZ37bfjZhttps://conf.tube/lazy-static/thumbnails/ae1dfc7a-8a99-4ca1-a39c-d0b9d99cdbb5.jpgImproving KDE Server Infrastructure - Akademy 2020The KDE Sysadmin Team has started doing some work behind the scenes to reduce "technical debt" in the way we manage the servers. Some manual tasks are becoming scripts, we have better documentation, and more things can be tested locally before putting them in the real servers. I will give a quick overview of these changes and our progress expanding them to more services.

However, unlike conventional platforms where we enjoy the stability of a well tested graphics stack, platforms based on the ARM architecture tend to be quirkier. In this talk, I'll be talking about the basics of how the Linux Graphics stack works touching on how technologies such as DRM, DRI, and Mesa interact with each other and the history behind how we've come to the current Gallium design in mesa. At the end of the talk attendees should have a better understanding of what goes on behind the scenes in the graphics world and a high level understanding of the Mesa/DRM architecture. Furthermore, this should help KDE developers gain a better understanding of mesa and allow for faster debugging of graphics issues on ARM devices.https://conf.tube/videos/embed/7a421c34-2608-4b34-bbeb-b03536ca59aehttps://conf.tube/w/nwq8vBjgK9kZuDGgaGaBNjhttps://conf.tube/lazy-static/thumbnails/ae4f1864-bd48-4db9-a3ee-35a06de3a9b2.jpgThe KDE Free Qt Foundation - Akademy 2020The KDE Free Qt Foundation was established in 1998 to keep the Qt toolkit free for KDE and all other free software projects building graphical user interfaces on Linux. It was a unique and creative solution to address concerns that licenses alone were not enough to keep free software free. It has held through the more than two decades of sometimes turbulent times Qt and KDE have gone through together. This presentation will tell the story of how this worked. The KDE Free Qt Foundation was established to give additional guarantees to the free software community which Qt's license didn't give. It resulted in an agreement between Trolltech, the owner of Qt, and KDE e.V., the non-profit organization representing the KDE community, which made sure that Qt would always be free software even if its owning company would change its course and stop releasing it under a free license. The agreement was tested several times. Trolltech was bought by Nokia and Qt changed its owner several times afterwards, today being owned again by a company exclusively dedicated to Qt, The Qt Company. The agreement through the KDE Free Qt Foundation brought KDE to the negotiation table whenever license changes were decided. Balancing freedom, community, business, and corporate planning in a way beneficial to all involved parties was a challenge not easily addressed. The question of open source business models and how companies relate to communities is still a source for much debate and different solutions are in place and explored in the industry. How did the KDE Free Qt Foundation succeed? How does it hold in comparison to what other projects chose? This presentation will answer these questions and tell the story of how the KDE Free Qt Foundation played its part in keeping Qt free. https://conf.tube/videos/embed/ae4f1864-bd48-4db9-a3ee-35a06de3a9b2https://conf.tube/w/6ddjQxf9ZAHTfuYu2T7qYFhttps://conf.tube/lazy-static/thumbnails/2a3236c5-8834-4179-8237-cf8e170e6bf7.jpgKDE's Products - Akademy 2020In KDE we create a myriad of things for different kind of people. We create frameworks, we create applications, we create environments. And we create it for different kind of people be it other people like us, high school students, 3rd party developers, distribution packagers and more than we can imagine (really!). In this presentation I would like to offer a framework to explain how we can embrace philosophies and ultimately technologies to make sure the Free Software community and its users are best taken care of. https://conf.tube/videos/embed/2a3236c5-8834-4179-8237-cf8e170e6bf7https://conf.tube/w/sxFN7bqTvbXHbwc6eaNpCehttps://conf.tube/lazy-static/thumbnails/d6fa2fc0-a32c-463c-b210-cabd25e50911.jpgLinux in Cars - So What? - Akademy 2020In this talk, Johan will talk about why cars - albeit with Linux - still are using so much custom software, and what use-cases need to be addressed to improve the situation. Johan has pushed for the adoption of open source in automotive for more than a decade. With a background from GENIVI and AGL, having been a part of the team behind the Qt Automotive Suite, and having worked as a supplier for numerous OEMs and hardware provides across Japan, USA, and Europe. He now continues this mission an architect at Mbition. Being a passionate user of KDE, and a believer in open source and open projects, Johan will talk about why he believes we got stuck after having put the Linux kernel into the car. How can we make progress, and what use-cases do we need to solve.https://conf.tube/videos/embed/d6fa2fc0-a32c-463c-b210-cabd25e50911https://conf.tube/w/91s4EM1V9PKn6aYdz7DKtGhttps://conf.tube/lazy-static/thumbnails/40d92bdc-3791-4a23-b92a-8d8adb14d91a.jpgIntegrating Hollywood Open Source with KDE Applications - Akademy 2020My GSoC 2020 project, entitled “Dynamic Fill Layers in Krita using SeExpr”, enables artists to create for the first time procedurally generated content directly within the Krita painting suite. This work is powered by Disney Animation’s open source library, SeExpr. SeExpr is an embeddable, arithmetic expression language that enables flexible artistic control and customization in creating computer graphics images. Example uses include procedural geometry synthesis, image synthesis, simulation control, crowd animation, and geometry deformation. This presentation will outline the challenges and pitfalls of integrating a Hollywood studio’s published work with a cross-platform KDE application. Aspects reviewed will include adaptations to the build system, dependency management, platform support, and bug triage and fixing. For users, UI and UX design and implementation will also be addressed. Layers are one of the core concepts of digital painting. They allow artists to control different parts of their artwork at once. A key feature of them is their ability to be resized, composited, renamed, grouped or deleted independently of the rest of the document. Patterns and textures are also essential components of an artist’s toolbox, allowing them to represent the intricacies of a physical material. They come in two forms: bitmap textures, which are images contained in e.g. PNG or OpenEXR files, or procedural textures, which are generated on the fly using their mathematical representation. KDE’s Krita painting suite supports patterns and textures through two types of layers, File and Fill Layers. However, neither of them let artists take advantage of procedurally generated content. My GSoC 2020 project, entitled “Dynamic Fill Layers in Krita using SeExpr”, allows artists to create dynamic content through a new, scriptable Fill Layer. To this effect, I integrated Disney Animation’s SeExpr expression language into Krita.

On the one hand, I will talk about strategies and how to design (unit and integration) tests. For example, what distinguishes a white box test from a black box test and why are both important? Moreover, I will look into which software architecture patterns exists that make your code better testable. A special concern will be, how this integrates best with Qt and QtQuick based code and the QTest framework. On the other hand, I will cover the integration into build system tooling and KDE CI infrastructure: What is CTest doing? Which helper macros do exist in Extra-CMake-Modules? And what important information can be see on build.kde.org? https://conf.tube/videos/embed/e1891b98-a627-4278-81ab-1188d7518affhttps://conf.tube/w/wiDpkLnnHLDyouxCKrptBrhttps://conf.tube/lazy-static/thumbnails/f568da9c-c15c-4825-b614-496cbd8b535b.jpgKIO: A Story of Young and Old Jobs - Akademy 2020Learn more about the KJob design, the KIO jobs like KIO::copy, the 3 new jobs to replace KRun, and choosing the right delegate. This talk will give an overview of the job mechanism as it used in KIO (starting with the base class KJob). First the "old" jobs will be presented, those that allow for instance to copy files, both locally and over the network. You will learn why they start automatically, and why copyjob.cpp has 2320 lines of code. Then you will discover the jobs that we added in the last two months, to replace KRun: CommandLauncherJob, ApplicationLauncherJob and OpenUrlJob. Finally, you will hear about how a concept called delegates is used to solve the inverse dependency problem, like a job in KIOGui showing up an "open with" dialog in widget-based applications. This talk is primarily intended for application developers, but it might also be very useful to potential contributors to KIO.https://conf.tube/videos/embed/f568da9c-c15c-4825-b614-496cbd8b535bhttps://conf.tube/w/xeuiDMhvRsZTawUJeQgf2uhttps://conf.tube/lazy-static/thumbnails/fced691f-6818-4832-bc70-1b87d7b8b146.jpgStatic Code Analysis with Gitlab CI - Akademy 2020The migration to GitLab earlier this year has opened up a lot of new possibilities to all KDE projects. One of them is introducing custom jobs on GitLab CI. In this talk I want to show the benefits of using static analysis tools and linters to automatically check code quality, and explain how to configure GitLab CI to run those tools automatically on each pull request or as a part of regular builds. https://conf.tube/videos/embed/fced691f-6818-4832-bc70-1b87d7b8b146https://conf.tube/w/f7uBFh6dCJjVJpYpxB4sQyhttps://conf.tube/lazy-static/thumbnails/724809de-d903-4367-b121-c54084bf1170.jpgVirtual Sprints - Akademy 2020After COVID-19, it is becoming increasingly hard to do a in-person sprint. But is that a bad thing? What are alternatives? Let's find out. I have organized two virtual sprints so far, - Plasma Mobile mini sprint - Plasma Virtual sprint Both sprints were using the BigBlueButton instance.

The "long-term" here means "beyond the participation of a particular person in the KDE community" and it's a useful tool in protecting KDE as a whole with Free Software principles. Copyright lasts a long time. Rules changes. Legal frameworks change. So copyright -- and by extension, the Free Software licenses that work with copyright to ensure the four Freedomes -- can last too long: so long that circumstances change out from under it. This talk will examine the FLA used by the KDE community and describe how it is used to mitigate change in licenses and copyright, and why you should probably sign one.https://conf.tube/videos/embed/5ab7b168-aa3f-4bfd-8e30-2e4b204296f0https://conf.tube/w/4qkzpgWfCV2SuMQnVZYbqihttps://conf.tube/lazy-static/thumbnails/1bb1549d-6fea-4ef8-bb24-f3d1fcc62499.jpgSuper Secret Plasma Features - Akademy 2020Did you know you could mouse wheel the volume icon in your panel to change the volume?

What UI/UX guidelines should the application follow? Is there any framework that implements these guidelines? Calindori is a calendar application created for Plasma Mobile but it can run on desktop environments as well.. Thanks to the Kirigami framework which implements the KDE Human Interface Guidelines (HIG), developers can choose the components that fit their needs and create convergent applications. In this talk, there will be presented the various Kirigami components as well as the underlying KDE HIG used in Calindori. The audience will be introduced to the primary components of Kirigami and learn how an application can be based on them. After the talk, attendants may be inspired to create their own Kirigami applications.https://conf.tube/videos/embed/a97502a5-8054-44ff-b15c-522ebe30d94bhttps://conf.tube/w/tKU21aTpPu8g9pfsgBWfWJhttps://conf.tube/lazy-static/thumbnails/e0c7c860-a925-4037-992d-ec4f7e19e6de.jpgGetting into KWin and Wayland - Akademy 2020This year I have ended up working on improving our Wayland experience on many fronts.

The rise of digital assistance features has shown that it's no longer enough to just focus on freely available source code to build such systems, the data needed for those is equally important. Fortunately, we do have two gigantic general-purpose data sets that model "the world", Wikidata and OpenStreetMap (OSM). Wikidata contains more than eight billion statements about almost 100 million items, and allows to model basically any kind of fact that isn't entirely transient. Containing also localized names and accompanied by more than 60 million media assets in Wikimedia Commons, Wikidata isn't limited to purely machine readable data, but also provides useful elements for presenting results to humans. OSM contains about 60GB worth of spatial data, ranging from country borders all the way down to individual streetlamps, and everything in between. A large variety of semantic annotations and cross-links to other databases such as Wikidata enable use-cases way beyond merely displaying a map. In this talk we will look at how those two data sets are structured, how they can be accessed, how to comply with their licenses, and how we can make use of them for our applications.https://conf.tube/videos/embed/26b7b3c2-4472-4445-a2fe-302b8208f6a0https://conf.tube/w/o2ncHdXoTQg4aJZKybiRiZhttps://conf.tube/lazy-static/thumbnails/b259dc45-2fca-444b-a75b-38d10038d67f.jpgNext Generation Application Management - Akademy 2020In this talk we will present a new cross-desktop specification to provide semantic grouping of processes together to be an "application". We will explain the many problems that we currently face, and how we can embrace an existing kernel technology used by system services to not only solve these but go beyond and expose existing new features. Plasma's sole job is to connect users to their applications. There used to be a time where one application was a process. ksysguard would show one easy to manage entry. Now Discord in a flatpak is 13(!) procesess. Have two electron instances and ksysguard is useless. We have backgrounds services that linger with indecipherable names. It doesn't work anymore on the desktop let alone the phone. We need metadata. This is a solved problem. CGroups are used commonly for your system services. Any sysadmin won't deal with an Apache proces, but the whole webserver as one cgroup. By embracing this not only do we have metadata providing a single-truth of the launched context, but also expose all of the kernel features reserved for cgroups. Separate network namespaces, hard CPU quotas, OOM protection that works, we can expose this either as transient modifiers or as sysadmin overrides. We've been doing a lot of subtle ground work over the past year to a lot of tiny edge cases where this metadata wasn't transferred correctly both within KDE and throughout the ecosystem. We will discuss what we've landed so far and what the future holds. https://conf.tube/videos/embed/b259dc45-2fca-444b-a75b-38d10038d67fhttps://conf.tube/w/vn9KWQycLm1wJRGxNyiuBThttps://conf.tube/lazy-static/thumbnails/edcd0994-7dc2-4a51-b9ee-8aa9eb8a2c39.jpgAPI Design and QML - Akademy 2020A presentation over QML API design sharing best practices to follow and things to avoid when creating QML APIs as well as a more general API-first design process.

Come learn about how to take this challenge on and help make KDE stronger with each year to come. During this keynote, we'll talk about some of the initiatives that KDE is involved in already that are helping make it more resilient, and identify some areas of opportunity. We'll also explore topics around building more diverse and inclusive communities, like collaborative communication, and ideas for outreach, in order to facilitate future growth. https://conf.tube/videos/embed/e6507c01-08d8-40ea-8894-e74db5f2e37dhttps://conf.tube/w/dmbWgBRBSjkjkC6bfKa3g8https://conf.tube/lazy-static/thumbnails/63ff4756-f1b5-4dfc-b849-dd392ce18e8d.jpgShowcasing Plasma Bigscreen - Akademy 2020Television sets have evolved from dumb boxes to interactive interfaces and intelligent screens driven by content from the cloud with support for voice assistance but all behind closed platforms, Plasma Bigscreen project is the open platform alternative providing interfaces and features similar to today's closed Smart TV Boxes, This talk will take you through the various features of Plasma Bigscreen and the technology that powers this open experience. Television sets have been around for decades, from being small TV sets receiving grainy content in its early years to ultra-high-definition large screen displays beaming content from all over the world, TVs have changed a lot in the past hundred years. With the evolution of TVs through the past decade, the experience of static viewing of cable-driven content has evolved into an interactive content-driven experience powered by the world wide web, powerful embedded SOCs and the growing need of wanting to use that large screen for simply more activities has laid the platform for what we call today as "Intelligent TVs". While the world is adapting to these "Intelligent TVs", The platforms that power the experience are still produced within walled proprietary gardens with a constant threat to User Privacy and User personal data embezzlement that creates the need for having more open platforms. The Plasma Bigscreen project is aimed towards supporting this open platform vision providing interfaces and features similar to today's closed Smart TV Boxes all powered by Plasma, Kirigami, and KDE Frameworks with a touch of Mycroft's open-source voice assistance platform bundled together to provide an experience beyond basic content consumption.

In the autumn of 2018, The Tail Company decided that a simple remote control was not enough for what they wanted to do with their animatronic tails, and they launched a crowd funding campaign to build a bluetooth based app controlled one. This presentation is the tale of how this turned into an experiment of working directly with the free software community, with all of the control software based on free software and KDE's Kirigami framework. Since then, the increasingly unfortunately named Tail Company has launched their animatronic ears, EarGear, controlled by the same software. You will also be able to see underneath the skin of both, to see an overview of how the app works across different platforms, and how the tail and ear hardware is put together.https://conf.tube/videos/embed/dd676f7d-3cd7-4233-9bb0-96ed7e232fa7https://conf.tube/w/5Je1kQ216WQAFVffJqtrLkhttps://conf.tube/lazy-static/thumbnails/2649cee2-b8b8-404b-8cf8-2b1f72ab5807.jpgKonquering the Droids - Akademy 2020In order to stay relevant KDE needs to expand from its traditional desktop space into the mobile world. While a fully free Plasma-based mobile experience is the dream, bringing KDE software to Android is an important stepping stone. It opens KDE software to billions of users, strengthens the brand of KDE and aligns perfectly with the “All about the Apps” goal. KDE already features a number of apps that are available for Android, but we need more contributors to make the effort sustainable. Last year Volker gave an excellent overview over the status of Android support in KDE Frameworks. Goal of my talk will be to give hands-on knowledge about the necessary steps and challenges when porting software to Android as well as to motivate people in doing so. Furthermore I want to raise the issue of defining a Google Play and F-Droid release process, which is to be discussed in a follow-up BoF session. I’ve been a regular contributor to KDE for the last three years, working on many projects including KDE Connect, Plasma and Plasma Mobile. I have ported almost a dozen KDE apps to Android and co-maintain the binary factory build infrastructure for it.https://conf.tube/videos/embed/2649cee2-b8b8-404b-8cf8-2b1f72ab5807https://conf.tube/w/8ipicNb3NZRTj5bZNaWCd7https://conf.tube/lazy-static/thumbnails/3b1df8c4-ff9d-460b-96c9-b1f8ccb3c1ce.jpgMyGNUHealth: GNU Health Goes Mobile with KDE & Kirigami - Akademy 2020GNU Health (GH) the Libre Health and Hospital Information System. GH is a social project that combines the socioeconomic determinants of health with state-of-the-art technology in bioinformatics, LIMS and clinical genetics. The GNU Health ecosystem works in the areas of demographics, socioeconomics, patient and institution management. It's been deployed in many countries around the globe, from small clinics to very large, national public health implementations. MyGNUHealth is the GH's Personal Health Record application that integrates to the GNU Health Federation, focused in mobile devices. We'll talk about what lead us to choose the KDE Kirigami framework to develop myGNUHealth, some technical insights and the community behind the project. In this talk we will talk about the benefits of Plasma mobile and the Kirigami framework provides to myGNUHealth. After a short introduction of the GNU Health philosophy and ecosystem, we will focus on the need of the Personal Health Record (myGNUHealth) that can be used both in mobile devices and desktop, placing the person / patient in the driver's seat, actively involved in the system of health. We introduce the technology used, the QT and Kirigami framework, and the interaction with the GNU Health Federation. From the community point of view, we'll talk about how the KDE friends are helping us in the development process.https://conf.tube/videos/embed/3b1df8c4-ff9d-460b-96c9-b1f8ccb3c1cehttps://conf.tube/w/cLk2bwSXAbs4PHGmtXeLgQhttps://conf.tube/lazy-static/thumbnails/5f44f90d-676b-49b0-b1d4-2b98ed4e3c1e.jpgChange Management - Akademy 2020The world hates change, yet it is the only thing that has brought progress ~ Charles Kettering Understanding and accepting change is not easy. There have been times where KDE has moved to a new platform and switch was not easy. We need to understand all aspects of change with importance to accept change. We have to understand that change not only gives the organization a significant advantage but it also helps us to progress over others. So, what are the effective ways to manage, accept, and increase acceptance to change? In this talk, we will improve our capability to understand and manage change. We will learn how to best roll out a change within KDE. We will be able to: • understand the critical role of change management • plan, control, and adjust to change • create a stronger working relationship with newcomers • create a culture of accepting changes across the KDE community • understand the success factors of changehttps://conf.tube/videos/embed/5f44f90d-676b-49b0-b1d4-2b98ed4e3c1ehttps://conf.tube/w/4yqtg2Y7S3yLAv1DMYQiaqhttps://conf.tube/lazy-static/thumbnails/1cd24bfa-172f-4e2e-abcd-37b74bc319e6.jpgOpen Source Compliance - Akademy 2020The proposed talk (or panel) will focus on Open Source compliance issues "While Free and Open Source Software development has tremendously benefitted from (open) technical standards, the rise of OSS usage and importance along with compliance requirements for different OSS license obligations still creates too many friction points and high costs in many organizations. This is especially true for today’s software supply chain, be in the commercial text or in the context of OSS projects. Almost all companies active in the software industry receive software packages from various different sources to be implemented in their products before sold or licensed. A very similar situation can be found when developing software in the context of OSS projects or foundations. Many different software packages are licensed under different OSS licenses leaving developers and project managers with the question of responsibility when distributing and selling OSS products. In today's jungle of OSS license compliance, it is more important than ever to know the very basics of copyright and licensing structures as well as some of the relevant tips and tricks for the most common OSS licenses.

During last year almost all module were ported to KConfigXT. We will see which benefits all modules (based on QWidget or QtQuick) got for existing feature like fixing reset/apply/default button state. But also new features allowed by this standardization from already landed feature to ideas for the future. Finally this talk will end with a discussion about which limitation we can encounter with KConfigXt current implementation and what to take in consideration when writing new module, porting existing one. After this talk you will know how system settings work behind the scene, and how to write new one and getting all benefits from KConfigXthttps://conf.tube/videos/embed/beca1f99-f1f8-4033-86da-3abb27edcf15https://conf.tube/w/9zdPLEWDJaadERuWAnL9QKhttps://conf.tube/lazy-static/thumbnails/456c8e78-aff4-4cbb-bc1c-9cb96794911b.jpgKDE Community Student Showcase Part 1 - Akademy 2020Every year a number of students join us through our student programs Google Summer of Code and Season of KDE.

First, we often encounter sample metadata as a CSV-formatted sample table, but I found no easy way to run a CWL workflow on each sample in such a table. To address this, I introduce looper, which scatters a CWL workflow on tabular data. Second, I have wanted to start an interactive terminal session using the same containerized computing environment that would run my workflow. This is useful to troubleshoot workflows, to explore data interactively, or to test different approaches. But it's challenging because the container images are tightly coupled to the CWL workflow. To address this, I introduce Bulker, which simplifies interactive use of multi-container environments. It keeps commands identical to native commands, but runs them in containers behind the scenes. With bulker cwl2man, you can extract the images from a CWL workflow and create a standalone interactive environment." Questions, comments?

Using the pipeline’s integrated graphical interface, an analyst can routinely assemble and review thousands of datasets in one batch within a few hours on a compute cluster. The software assembles de-novo complete viral genomes from amplicon-derived shotgun reads potentially sequenced with extremely high local coverage variability as well as specific bacterial genes from whole genome shotgun reads. The software was successfully deployed as the assembly module in a system validated according to good clinical practices (GCP). To this end, it guarantees deterministic results, full provenance data and ensures the integrity of the inputs and intermediate datasets through cryptographic checksums.

CWL is commonly used for computation- and data-intensive processing of large datasets. These tools and workflows may be applied to many datasets. However, another application of CWL is to encapsulate the logic for reproducing research analyses, including statistical analyses and generation of graphics for publication. I provide an example that illustrates this process for a differential gene-expression analysis. In addition, I introduce a Web-based application called ToolJig (https://github.com/srp33/ToolJig) that facilitates creation of CWL documents for this purpose. I welcome your feedback."

Especially, it is important to see how well a workflow engine is conformant with the CWL specification to guarantee the portability of workflows between workflow engines. However, in the current situation, the only way to do that is to read the documents for each workflow engines. "This talk presents a conformance badges to show how well a given engine passes the conformance tests of CWL specification for each document class (e.g., CommandLineTool) and for each process requirement. Once developers of workflow engines provide them in their documents, users can easily see the overview of the supported and unsupported features. This talk also shows how developers provide these badges by using the official test suite. Finally, this talk briefly presents another topic that builds an ecosystem to collect and to utilize workflow metrics based on CWL-metrics." Questions, comments?

Many of them target a specific environment; few of them make it possible to execute an entire workflow in different environments, e.g. Kubernetes and batch clusters. We present a novel approach to workflow execution, called StreamFlow, that complements the workflow graph with the declarative description of potentially complex execution environments, and that makes it possible the execution onto multiple sites not sharing a common data space."

A component developed by CRIM named Weaver is presented to demonstrate through examples the integration of containerized Docker applications to execute leading edge technologies and algorithms with Web Processing Service (WPS) interfaces and Open Geospatial Consortium (OGC) APIs. "The talk presents four examples, illustrating applications for object region proposals, satellite imagery classification, climate data analysis and LiDAR point cloud classification. Distributed server architecture and interoperability capabilities of Weaver are also presented with pre-deployed WPS providers. The examples demonstrate how advanced processing pipelines and rapidly move from research and development phases to deployed web services in production environments."

The main goal is to be able to run any standardized workflows written in CWL / WDL (or in bash command) inside a container created from any Docker image, with very heterogeneous types and sizes of input. The key element is to be able to isolate and resource-manage individual workflow runs, without relying on a pre-configured cluster, using a serverless architecture. We also set up many ways to monitor and analyze workflow runs to make the workflow development and implementation process more efficient." Questions, comments?

Sapporo has two components: Sapporo-service (https://github.com/ddbj/SAPPORO-service) provides an API server that accepts the request to run a CWL workflow, and Sapporo-web (https://github.com/ddbj/SAPPORO-web) provides a browser-based GUI to control the workflow runs on the WES API. This video provides a live demo to show how to deploy Sapporo-service via docker-compose and run a workflow via command line and the Sapporo-web GUI hosted on github pages (https://ddbj.github.io/SAPPORO-web/).

Gray Roncal, Johns Hopkins University APL Summary: "Emerging neuroimaging datasets (collected with imaging techniques such as electron microscopy, optical microscopy, or X-ray microtomography) describe the location and properties of neurons and their connections at unprecedented scale, promising new ways of understanding the brain. These modern imaging techniques used to interrogate the brain can quickly accumulate gigabytes to petabytes of structural brain imaging data. We developed an ecosystem of neuroimaging data analysis pipelines that use open-source algorithms and the Common Workflow Language to create standardized modules and end-to-end optimized approaches. As exemplars we apply our tools to estimate synapse-level connectomes from electron microscopy data and cell distributions from X-ray microtomography data. To facilitate scientific discovery, we propose a generalized processing framework, which connects and extends existing open-source projects to provide large-scale data storage, reproducible algorithms, and workflow execution engines."

To learn more, visit https://libregraphicsmeeting.org/2021/ One common criticism of FLOSS software is that it does not conform to standard notions of UI/UX. These standards have been set by large corporate players in the software world. While some of these critiques are arguably quite valid in specific cases, there's also an argument to be made that one of the great strengths of FLOSS is the capacity to allow and enable diversity in ways and methods of interaction. This presentation will try to make the case for a more diverse, inclusive interface culture. Current interface culture is dominated by a few large corporate players: google/Alphabet, Apple, Microsoft. For many of us who spend countless hours working, socializing and amusing ourselves while using technical media, these powerful players have a huge influence on our experience of everyday life. Our perception of the world around us and how we see ourselves in, it is mediated by the decisions of a few privileged managers, programmers and designers, mostly male and white on the west coast of the United States. To suggest any other way of living in a networked society is to risk being perceived as blasphemous, uncool, out-of-touch, escapist or simply absurd. These interfaces have become so embedded in our conception of reality that we now have a crisis of the imagination, where it is difficult to even think of anything different. FLOSS applications are by no means perfect but they might show us some possible methods for a more intersectional idea of interface culture.https://conf.tube/videos/embed/7e803c79-3c70-47b9-ba0d-7a3e7366207ehttps://conf.tube/w/oxD4tHomBExTRm6biZsZfdhttps://conf.tube/lazy-static/thumbnails/b693f247-78d6-4d6b-a8f9-cdc8b825f57c.jpgLGM 2021 - UpStage mobilised by Helen Varley JamiesonThis video was recorded on May 27 2021 as part of the Libre Graphics Meeting 2021, online. To learn more, visit https://libregraphicsmeeting.org/2021/ The online performance platform UpStage is undergoing a complete rebuild, to remove its dependency on Flash and bring it up to date with current technologies, including functioning on mobile devices. The rebuild has been made possible thanks to the Creative Europe funded project "Mobilise/Demobilise", which will present a series of cyberformances on the theme in September to launch the new platform. A global team of open source developers, interface designers and artists are working on the project. This presentation will explain the project and give a live preview of the features of the new platform. UpStage was originally developed in 2003 as a venue for live, online artistic performances: remote artists can manipulate digital media in real time for online audiences, who only need to open a link in a browser to join the performance. The new platform is being developed using VueJS, HTML5, MTTQ, Python and other technologies. "Mobilies/Demobilise" is an artistic collaboration between UpStage, Theater InterAkt (Sweden) and Schaumbad Freies Atelier-Haus Graz (Austria), with administrative support from the Centre for the Cultivation of Technology (Germany) - an organisation that provides infrastructure support for small open source projects. Alongside the software development, a creative project is exploring the theme of mobilisation and demobilisation, to develop a series of networked performances (cyberformance) that will launch the new platform in September. Following the launch, UpStage will be available for artists to use either as a hosted platform or installed on your own server. Interested developers are welcome to join the project at https://github.com/upstage-org/mobilise This presentation will give a background to the project and the team, explain the technology stack and give a live demo/prev...https://conf.tube/videos/embed/b693f247-78d6-4d6b-a8f9-cdc8b825f57chttps://conf.tube/w/1pEoSY2BruG3tVnZ1Jr6DMhttps://conf.tube/lazy-static/thumbnails/034dc4a4-a2cd-496a-91d0-78d2d6e4f88b.jpgLGM 2021 - Terminedia-paint: an utility to draw ASCII/Unicode art interactively by João S. O. BuenoThis video was recorded on May 27 2021 as part of the Libre Graphics Meeting 2021, online. To learn more, visit https://libregraphicsmeeting.org/2021/ Based on the Terminedia framework which enables programs to draw on the text-terminal screen, a simple, yet fun-to-use application created to edit images as text or use the framework capabilities in a more interactive form. One can create pieces of ASCII art work on the same way more traditional image drawing takes place: by interacting with mouse and keyboard. The noveau thing is that on the terminal a "pixel" is not only a color - it fatures a character, a backcground, and even a text-transform effect as well (underline, unicode encircled characters, etc). In 2020 I presented the terminedia project I am developing enabling programmatic creation of images using the full extend of both unicode and terminal effect capabilities. This year, with the maturing of that project, a short demonstration of how it is simple to create terminal-interactive apps using Python, and have an actual fun way to create new ASCII art material. The demo is about usage and examples, and also a quick look at the source code to check how to add new features.https://conf.tube/videos/embed/034dc4a4-a2cd-496a-91d0-78d2d6e4f88bhttps://conf.tube/w/c6phufM5cvtsBLquBXSHHwhttps://conf.tube/lazy-static/thumbnails/59d597f2-9c8e-4668-9049-b1a74ecf184c.jpgLGM 2021 - Cascade: live coding with CSS by Raphaël BastideThis video was recorded on May 27 2021 as part of the Libre Graphics Meeting 2021, online.

To learn more, visit https://libregraphicsmeeting.org/2021/ By now most free and open-source software enthusiasts will have heard something like: "Free software is okay for hobbyist but not professionals." That is wrong and our agency has set out to prove it. To outsiders Freehive looks like most creative agencies doing a variety of design, development, and animation work. The big difference is Freehive only uses free and open-source tools to do it. See how a suite of freely licensed, widely available tools have enabled us to execute on creative ideas for paying clients without a single compulsory software subscription. This presentation by Ryan Gorley, the Creative Director at Freehive, is part show-and-tell and part invitation to others who have the opportunity to choose their tools to choose free and open source software.https://conf.tube/videos/embed/42d4040c-696c-4398-ad44-f5c15e07c839https://conf.tube/w/jBSeKS9iMaeeyHg6BpTP29https://conf.tube/lazy-static/thumbnails/96c67cd2-b89e-486b-9701-59f56ccd32e6.jpgLGM 2021 - Webtoonize by Cédric GémyThis video was recorded on May 28 2021 as part of the Libre Graphics Meeting 2021, online.

It's geared towards playful graphic exploration, creating SVG images for pen plotters, and is a great tool for automated/headless image generation. In this lightning talk we will quickly demo what Shoebot can do, and what is made possible in the new 1.4 version, the most significant update in recent years. Shoebot is a creative coding environment designed for making vector graphics and animations with Python. It's geared towards playful graphic exploration, creating SVG images for pen plotters, and is a great tool for automated/headless image generation in general. After years of slow development, we have just published the most significant update yet, with lots of improvements and new features ready to explore. Some of our favourite highlights are variable font support, advanced typographic options, and pretty fast rendering. On the development side of things, a new unit test framework was put in place, making it possible to find and crush several bugs. As a result, Shoebot is more reliable than ever. To top our excitement, we have launched a new extension for the Atom text editor. It's now much simpler and pleasant to experiment with scripts, shapes and outcomes. We've put a lot of work on other parts of Shoebot as well: the project documentation was redesigned with many additions and edits, along with a cleaner project home page. In this lightning talk we will quickly demo what Shoebot can do, and what is made possible by all these recent additions.https://conf.tube/videos/embed/3eff21d2-e4bf-4943-8bcb-84c52df851afhttps://conf.tube/w/j8qubTvqbXa6uzagmCRC54https://conf.tube/lazy-static/thumbnails/92cdcad4-3556-4f79-8453-d6f848a763a3.jpgLGM 2021 - How to simulate rotating space stations in VR by Tom LechnerThis video was recorded on May 28 2021 as part of the Libre Graphics Meeting 2021, online. To learn more, visit https://libregraphicsmeeting.org/2021/ How to simulate rotating space stations in VR with open source software. Tom will discuss how to use open source software such as Godot, Blender, and other software to construct large rotating space stations in VR, with mostly accurate physics. Due to its immersion, VR is the best medium to explore physics effects of so called spin gravity. Also designing anything for a cylindrical landscape presents a number of interesting challenges. Fortunately, these can all be addressed with open source software.https://conf.tube/videos/embed/92cdcad4-3556-4f79-8453-d6f848a763a3https://conf.tube/w/tcck4XKka2LJoXGYSAXCxYhttps://conf.tube/lazy-static/thumbnails/dc36e829-d6c0-435c-97f3-463802cbe146.jpgLGM 2021 - Autograph - dancing puppet in Blender by João S.

To learn more, visit https://libregraphicsmeeting.org/2021/ In this talk, we will present a compression/decompression algorithm, integrated into the G'MIC opensource image processing framework (https://gmic.eu), that allows us to store more than 890+ non-parameterized color transformations to apply on images (also known as "Color LUTs", or "CLUTs"), in less than 3.5 Megabytes. This algorithm determines a sparse encoding of any input color LUT and defines an associated (lossy) reconstruction scheme, based on the application of multi-scale, volumetric, anisotropic, diffusion PDE's. The reconstruction process can be parallelized and can reconstruct a CLUT at any spatial resolution. The whole compression algorithm roughly achieves a 99% compression gain over the original CLUT data.https://conf.tube/videos/embed/4327a41c-7d18-44f4-bc48-a55c03bca6c5https://conf.tube/w/oBWr4CfoPXABhbRXznfNoFhttps://conf.tube/lazy-static/thumbnails/b72da0a0-9bba-4b29-b309-ef699fd6fbfb.jpgLGM 2021 - State of the PIXLS by Mica Semrich and Patrick DavidThis video was recorded on May 29 2021 as part of the Libre Graphics Meeting 2021, online.

To learn more, visit https://libregraphicsmeeting.org/2021/ This is modified talk I gave at LibrePlanet, it focuses on my adventure using the Patreon platform to get funding to work on Inkscape and why I think this is important to allow users to have the freedom to modify code and they can only do that through a developer. Why should users be involved in our projects? Why should we ask them for money and what do they get out of being involved if we invite them? Come hear my thoughts on trying to build funded development within the Inkscape project. As an independent contractor, I've often made features which large companies want because they can afford to pay for it to be made in one go. But what if you're a regular user and your needs, your features are not getting the attention that they need.

To learn more, visit https://libregraphicsmeeting.org/2021/ The term zine comes from small magazine/fanzine, and it mostly refers to DIY and self publications with low production cost, intended for sharing niche skills, personal, obscure, and creative stories. Making a zine for an A4 size printer, requires some paper folding and arrangement of signatures. In this talk I will demonstrate how I moved my favorite A5 zine template from Scribus to Python FPDF scripting. The process deals with how to parse text and create signatures (aka making two or more pages within one A4 page) that can fold into each other to create a booklet. Moreover it covers how to place titles and images within the text, in order to generate a PDF document ready for the printer without touching the mouse. I will of course briefly illustrate what signatures are by showcasing some of my own tech related zines. At last, I'd refer to the possibility of introducing some random or dynamic patterns when generating print material with a script.https://conf.tube/videos/embed/df4fb8a5-47ca-44f2-a2d6-9c41046275b3https://conf.tube/w/oFS8VmRBnnLSiKLBWFdtKohttps://conf.tube/lazy-static/thumbnails/b7b9f48e-606b-42a6-9dae-8def47551970.jpgLGM 2021 - Dithering and Colour and Noise, Oh My! by AmysparkThis video was recorded on May 30 2021 as part of the Libre Graphics Meeting 2021, online. To learn more, visit https://libregraphicsmeeting.org/2021/ In this talk, we will examine the state of the art of digital halftoning techniques, how they can be used, and how these were implemented in Krita to improve the rendering quality of gradients. Spatial dithering, also known as digital halftoning, is a technique used to simulate a higher color depth in images using a limited color palette (1). It approximates shades of colour not available in the palette using a spatial distribution of available colours, taking advantage of the human eye's tendency to average colours in a neighbourhood. This technique has its origins in the printing industry: halftoning is the process of rendering an image as a pattern of coloured dots, exchanging color resolution or bit depth for spatial resolution (1). Common issues that are addressed by dithering are colour shift and false contours . When an image is quantized, the luma and chroma of the area covered by each pixel is classified into one of the available colors in the device's palette, resulting in a shift that may be visible to the naked eye. When there are insufficient colours to represent an otherwise smooth transition, banding, or the formation of false edges may occur (2). Low level graphics libraries, image processing toolkits, as well as graphics drivers and output peripherals themselves, use dithering as a computationally cheap way to work around these issues. Throughout its history, Krita used 8-bit resolution and the sRGB color space exclusively to render gradients, ignoring the color space and bit depth of the image. This resulted in very visible banding artifacts, a behaviour that was reported in bug 343864. During the last month of 2020 and the start of 2021, we implemented high dynamic range gradients by rendering the gradient in the image's color space, with 16-bit as a minimum depth, and adding ditherin...https://conf.tube/videos/embed/b7b9f48e-606b-42a6-9dae-8def47551970https://conf.tube/w/njMejN4j5yGPYu79cgJqvnhttps://conf.tube/lazy-static/thumbnails/acaf2c6c-5533-40ae-9899-b37268ad1767.jpgNext Generation Internet Linked Data WebinarIn this free online event, projects from across the Next Generation Internet universe present their state-of-the-art work on Linked Data and other forms of metadata.

Building, optimizing and deploying release APKs We create more and more mobile-friendly applications, many of which also work on Android. But having to cover the distributor role there as well, how do we actually go about releasing our apps there? Targeting Android with our applications is interesting both for reaching a like-minded community on its FOSS variants such as LinageOS as well as for the vast user base of its proprietary variants, and is in line with KDE's goal of improving our application delivery. However, it is also up to us to wear the distributor hat and take care of packaging and delivery to the respective app stores there. While we have the infrastructure to build nightly debug packages targeting Android for about 25 apps, and distribute those via a dedicated F-Droid repository, only very few applications have proper releases for Android. All of those use custom solutions to build their release packages, unlike on other platforms we have no common infrastructure for this. In this talk we are going to look at ongoing efforts to expand the existing setup of Craft and Binary Factory to also cover Android release packages. Craft and Binary Factory are already used to build Windows, macOS and AppImage packages, covering Android as well promises less dependency, package and infrastructure maintenance work. Building release packages isn't as easy as changing a few build flags though. Particularly for mobile apps it is useful to optimize the package size by ensuring we only include what is absolutely necessary, both for code and data. At the same time it's crucial the package is complete, especially regarding translation catalogs. We'll therefore look at ways to inspect, analyze and optimize the release packages. Finally, a package itself isn't enough for an app store presence, we also need the associated metadata describing the application, e.g. with texts, tags/categories or screenshots. Most of this usually exists in form of AppStream metadata already, and we'll see how that can...https://conf.tube/videos/embed/20f27b59-e616-49aa-8999-a1f197ee9c80https://conf.tube/w/9C2ubAtk928efvx8G5GdzEhttps://conf.tube/lazy-static/thumbnails/45d0ccfc-3256-4749-b3e1-e69c695b2710.jpgCommunity's Adventures in Analyticsland - Or the State of the Community Through New AnalyticsThings got a bit quiet and slow again regarding the community data analytics. The universe has a weird sense of humor, admittedly it went out of control this time. But behind the scene, things have still been happening in the community at large and with our community data analytics tooling in particular. This talk will explain what's new in that department and produce a new report on the community adventures. No line will be stolen from Lewis Carroll for this talk... until we decide otherwise. In this talk we will pick up where we left in 2018. We focused quite a bit on the history of the tools we use for community data analytics. Because of this we showed only a few phenomena which could but didn't do a large study of the community. Since then, more features have been added to our tooling which allow to leverage more data for GitLab based projects. Since KDE now switched to GitLab for a little while, it is time to take a closer look at the interactions happening there. This is especially interesting since even quite a bit of traffic from mailing lists moved on that platform. We will revisit several older topics under that new light. In particular, we should have a much more precise reading of the contributor networks than ever before.

In Qt 6 another possibility is approaching adolescence: you can use the same declarative QML language to create 3D applications too. In this talk we'll explore some of the possibilities: 2D applications for working with 3D content (like CAD, 3D design and 3D printing applications), 3D applications which also contain 2D user interfaces mapped onto the surfaces of the objects (games and simulations), and fully immersive 3D user interfaces. We hope that with all this power available via such an easy language as QML, the community can begin to develop entirely new categories of applications.https://conf.tube/videos/embed/679a8c3c-532c-4416-9860-0f90f75441c9https://conf.tube/w/6M1sYBUBa8NJe1FaytncTLhttps://conf.tube/lazy-static/thumbnails/2ec67317-d0e3-4c13-a3f4-58a8d3f581fe.jpgO² a WIPThe process of creating design in an Opensource Universe.

QML is a declarative language (like CSS and JSON). Qt Quick is the name of the QML based framework for defining modern user interfaces. To break the cycle of painstaking feedback loops between designers and developers the Qt Company is also developing Qt Design Studio a graphical editor for Qt Quick and QML. Qt Design Studio comes also as a free community version for non-commercial users and is available for Linux. This talk is showing how Qt Design Studio with Qt and QtQuick can be used to create applications with a modern user interface and how to involve UX designers in the development process. The free community version is freely available for non-commercial users and can be utilized to improve and speed up the development of Qt/QML Open Source applications.

What is the process like to take an idea from nothing and build, develop, and maintain it over years of time? What are the bright sides and the dark sides of working on an Open Source Project primarily on your own for such a significant amount of time? Are there maybe even dangers? This talk tries to shed some light on this. Oftentimes when imagining how Open Source Software is developed, the following sort of picture is painted: teams of dozens of developers coordinating happily, handling constant software maintenance with a smile on their faces and often provided with company funding. This is an ideal picture that sadly and all too often doesn't reflect reality, especially for small to medium sized or highly specialized projects. The question remains: what is it like to create, develop, and maintain an Open Source project independently or with a small-sized team and an unsure funding situation? Over seven years ago Gina Häußge created her own Open Source Project "OctoPrint" and has been running and maintaining it ever since; full time since 2014 and funded entirely by donations and sponsors since 2016. In this talk Gina will give some insights into her every day job as a full time independent OSS developer. She will be speaking about the good, the bad, and the ugly sides of her daily work while providing hints to other OSS developers on developing and maintaining a long term project and how to handle challenges that may be commonly encountered. https://conf.tube/videos/embed/b7126318-1656-4024-b8dd-ea37751ca1fahttps://conf.tube/w/7xEX31kVaS3BKWWvwM5Jadhttps://conf.tube/lazy-static/thumbnails/3502e455-3665-4391-ac6c-36f1dc95c36e.jpg39 - Open Source at SVTThe foss-north crew discuss and explain copyright and licenses.

How do you convince your employer and colleagues that using Nix is a good idea? Let me tell you how I did it at Chatroulette (https://about.chatroulette.com/) and show you that you can easily do it at your company too. The main programming language at Chatroulette is Scala, a hybrid OOP-FP language that runs on the JVM, even though we only make use of the functional subset. We run the entire system on Kubernetes (Istio / Envoy) and deploy our microservices as Docker containers. Introducing Nix in such a big system - running in different platforms - might not seem trivial but you would never know if you never try! The talk will also touch on the current state of Nix in the Scala community. How many use Nix? How many don't know what Nix is? What can we do better? The ultimate goal of this talk is to give you the itch to at least think about introducing it at your company.https://conf.tube/videos/embed/d8977be5-1edb-46d8-b59b-02c2ce028dbchttps://conf.tube/w/tfnwwESn2KxA1k5sx3LaWxhttps://conf.tube/lazy-static/thumbnails/dca86c35-613f-46e3-9549-b5a43126097f.jpgNix modules: Improving Nix's discoverability and usability[Nix modules: Improving Nix's discoverability and usability](https://cfp.nixcon.org/nixcon2020/talk/K89WJY/) - Eelco Dolstra 2020-10-16 Nix's configuration language is quite powerful, but suffers from a lack of discoverability, usability and consistency. In this talk, I'll describe an experimental Nix module system that provides a consistent, discoverable mechanism to write configurations such as packages and NixOS systems, and show how this enables a better user experience for both new and advanced users. Nix's configuration language is quite powerful, but suffers from a lack of discoverability, usability and consistency. To name just a few examples: There is no easy way to find out from the command line or from the REPL what arguments are supported by functions like stdenv.mkDerivation or buildPythonPackage. Mechanisms like the .override attribute provide an almost unlimited ability to customize packages, but the only way to figure out what you can override is to read the source of the Nix package, and writing overrides is often black magic. NixOS has a nice self-documenting module system, but Nix packages are written in a completely different functional style. The Nix CLI doesn't know anything about package functions, .override and .overrideDerivation, the NixOS module system, the Nixpkgs config attribute set, Nixpkgs overlays, or any other customization mechanisms that have emerged over the years. The syntax and semantics of Nix expressions are often an obstacle to new users and have a steep learning curve. In this talk, I'll show an experimental Nix module system, similar to the NixOS module system, to replace the "functional" package style using in Nixpkgs. This means that functions like mkDerivation or buildPythonPackage as well as packages become modules that can build on each other. For instance, the "GNU Hello" package is a module that inherits from the unixPackage module, which in turn inherits from other modules like derivation.

The innovation Nix brought is now present in almost all recent packaging tooling, while Nix hasn't been adopted yet by a larger audience. Why should we care about that?

AOSP projects often contain long and complicated build instructions requiring a variety of tools for fetching source code and executing the build. This applies not only to Android itself, but also to projects which are to be included in the Android build, such as the Linux kernel, Chromium webview, MicroG, other external/prebuilt privileged apps, etc. Robotnix orchestrates the diverse build tools across these multiple projects using Nix, inheriting its reliability and reproducibility benefits, and consequently making the build and signing process very simple for an end-user.https://conf.tube/videos/embed/cb28f855-5cee-40f8-aeaa-022f62b8ade5https://conf.tube/w/wFCHuvUQkUcYiFJ3ML49U7https://conf.tube/lazy-static/thumbnails/f87acb21-a979-4e84-8d97-e3b85e4a2dc6.jpgBringing NixOS to my school[Bringing NixOS to my school](https://cfp.nixcon.org/nixcon2020/talk/DHGPLN/) - Marc Schmitt 2020-10-16 EPITA, a French school of engineers in computer science, is bringing NixOS to its students. Here is a presentation of the challenges of maintaining an infrastructure of more than 800 machines used by students.

Nix package manager has a lot of useful properties, and NixOS permits to expand the use of such properties beyond just installing packages. However, while Nixpkgs behaves mostly like a library, with overrides sometimes used to change even the fundamental assumptions if these are not used by some packages (see, e.g., pkgsMusl), NixOS is typically perceived closer to a framework. Using NixOS service management means committing to the module system (but Nixpkgs overrides are still useful), nonatomic /etc switch, systemd, NixOS driver management, etc. This creates a leap of faith, as installing Nix side-by-side breaks only storage quotas, but installing NixOS breaks everything; and leads to some duplication with nix-darwin and similar projects. In the talk I will tell what and how to reuse from NixOS now, what NixOS changes could simplify use of NixOS as a shared knowledge collection about running services between different projects with different commitment level, and how a bit of commitment to dumping the core assumptions turns some features from a weird dream into table stakes.https://conf.tube/videos/embed/edc05657-02b6-402c-835c-3e4bd84f5318https://conf.tube/w/s87QiWZytb3vtMDkMVobgvhttps://conf.tube/lazy-static/thumbnails/d38c05c1-b974-4977-a9a9-b99fe09bd20b.jpgnix-processmgmt: An experimental Nix-based process manager-agnostic framework[nix-processmgmt: An experimental Nix-based process manager-agnostic framework](https://cfp.nixcon.org/nixcon2020/talk/TW79FU/) - Sander van der Burg 2020-10-17 Nix is package manager that offers all kinds of powerful features to make package deployments reliable and reproducible. Although Nix can be used to conveniently deploy packages, on various operating systems (such as Linux and macOS), and even allows unprivileged users to deploy packages, deploying services (such as PostgreSQL and Apache HTTPD) still has its limitations. Currently, Nix-based service deployment is solved by a small number of solutions: NixOS requires you to adopt a fully Nixified Linux system and uses systemd as a process manager. nix-darwin only works on macOS with launchd as a process manager If you are using Nix on a conventional Linux distribution, a different operating system (e.g. FreeBSD), with a different process manager (e.g. supervisord), or as an unprivileged user, then there is no off-the-shelf solution that can help you (yet) to conveniently deploy Nix-provided services. The nix-processmgmt framework (https://github.com/svanderburg/nix-processmgmt) is a prototype that tries to provide universal Nix-based service deployment on all systems where Nix can be used. It offers the following features: * It uses simple conventions for describing process instances, e.g. function definitions and function invocations * It works with high-level deployment specifications that can universally target the following process managers: sysvinit, bsdrc, systemd, supervisord, cygrunsrv and launchd * Tested on the following operating systems: Linux, macOS, Cygwin and FreeBSD * Automatically derives the activation order from process dependencies * Allows you to deploy multiple instances of the same service * Unprivileged user deployments In this talk, I will provide background information about this framework, describe how it works, and show a number of real-life usage scenarios using commonly...https://conf.tube/videos/embed/d38c05c1-b974-4977-a9a9-b99fe09bd20bhttps://conf.tube/w/jwZK4MbcqWyvcRiaGGr6zihttps://conf.tube/lazy-static/thumbnails/961864e1-357e-4e1e-a15b-954ff9829067.jpgAutomating deployment with Hercules CI and NixOps[Automating deployment with Hercules CI and NixOps](https://cfp.nixcon.org/nixcon2020/talk/DDXWDY/) - Robert Hensing 2020-10-17 Introduction to Hercules CI, NixOps and a step by step demonstration of setting up a continuous delivery pipeline with these tools.

DevOps students have to test their skills in a real-world exam, what's better than scripting this using NixOps in order to reuse it ? They will be provided with their own user account on the Bastion and access to a jump user account, WireGuard will be autoconfigured on the host to enable access to their KVM host directly. The main point is controlling the KVM guests "declaratively" and giving choice to the students to choose their guest OS: Debian or NixOS.

Have you ever wished once that you could use the Nix language for something else than Nix ? To write a small project-specific script, or to generate a configuration when having to deal with horrendous YAML templating languages ? Nix may have its flaws, but it uses a simple yet powerful language - fundamentally, a lazy JSON with higher-order functions - that could very well be used to generate other configurations than Nix packages. In this short talk, I present the Nickel configuration language, which is an ongoing effort to make a standalone offspring of the Nix language , and while doing so, takes the opportunity to add new capabilities to the language.https://conf.tube/videos/embed/eedce3df-b944-42e9-b9a0-3b168210c8b5https://conf.tube/w/hbuNG7bG1mRTPNpRNDrLQQhttps://conf.tube/lazy-static/thumbnails/83096871-e15a-4ac2-b981-2e2bd2abecf8.jpgNix × IPFS[Nix × IPFS](https://cfp.nixcon.org/nixcon2020/talk/EUKUDK/) - John Ericson 2020-10-17 IPFS is a natural way to distribute sources and build artifacts for Nix because of their shared focus on immutability, content addressing, and decentralization. We at Obsidian Systems have spent the past several months integrating the two, and we're excited to present the result to the the Nix community, along with the future directions this work unlocks. See also https://github.com/obsidiansystems/ipfs-nix-guide for a tutorial.https://conf.tube/videos/embed/83096871-e15a-4ac2-b981-2e2bd2abecf8https://conf.tube/w/vJpcDLx6DBHhB5ovFjQk3Uhttps://conf.tube/lazy-static/thumbnails/f0c48eba-6067-460f-aae0-1ca4e4bb1e94.jpgNixOps for Proxmox[NixOps for Proxmox](https://cfp.nixcon.org/nixcon2020/talk/7RKBTE/) - Ryan Lahfa 2020-10-17 We will explore how to build and manage dozens of NixOS virtual machines in a Proxmox cluster using NixOps in a declarative fashion. Managing a fleet of NixOS machines can be achieved using supported backends of NixOps or other tooling (Disnix, Krops, Morph, etc.), but most of them do not solve the "initialization" of your host, e.g. installing NixOS, starting the node, except if you're using a major cloud provider like AWS for example. If you're running your own mini-datacenter and want to manage the whole infrastructure end to end, using the Nix language, it would prove quite difficult. nixops-proxmox is one step towards a NixOS-heavy datacenter, e.g. storage backends, PCI devices, network adapters can be considered as resources and ultimately all of them can be controlled from a "reproducible" and centralized Nix expression. This talk will feature how to use IPv6 (!) inside a NixOps plugin, especially useful for IPv6-only networks.https://conf.tube/videos/embed/f0c48eba-6067-460f-aae0-1ca4e4bb1e94https://conf.tube/w/w9n58zF5bpdEQcL5GFscUNhttps://conf.tube/lazy-static/thumbnails/f41d1876-9a7f-4f43-909f-d1a8f69edd02.jpgHow Nix grew a marketing team[How Nix grew a marketing team](https://cfp.nixcon.org/nixcon2020/talk/83RFWZ/) - Rok Garbas 2020-10-17 In my talk I'd like to go over: 1. Why Nix community needs a marketing team 2. What have we been up to in marketing team in the last 6 months 3. What are the plans for the next 6 months Marketing, and non-technical work in general, is all too often an afterthought for developers or worse it is viewed as something negative. I really wish it weren’t the case. Having clearly defined problems, audience and strategy should be as important to us as having clean and tested code. This is important for Nix. This is important for any project that aims to succeed.https://conf.tube/videos/embed/f41d1876-9a7f-4f43-909f-d1a8f69edd02https://conf.tube/w/iFMCDsa74yTksbm6ihgsbnhttps://conf.tube/lazy-static/thumbnails/8f397c61-4bd0-4a03-97cc-a0c381272439.jpgUsing CWL at scale in the Genomic Data CommonsPresenter: Shenglai Li Summary: "The National Cancer Institute’s Genomic Data Commons (GDC) has been using CWL since 2016. We have completed over 1,000,000 CWL workflow jobs on both on-prem and AWS combined with cwltool as our workflow engine. We have some limitations in current implementation that cwltool couldn’t parallelize the steps to multiple instances so we can not consistently leverage AWS spot instances. However, since the GDC pipeline automation system (GPAS) was designed to be easily configured with a different CWL engine, we are always investigating other workflow engines. We also want to share some of our experience including cwltest, modularizing, and improving the code readability. This project has been funded in whole or in part with Federal funds from the National Cancer Institute, National Institutes of Health, under Contract No. 75N91019D00024 Task Order 17X147F15" Questions, comments?

The platform, Polus, focuses on using interoperable plugins for image processing. The goal is to build a platform to build workflows and to run these workflows on cloud and/or HPC resources. We will talk about our journey towards adapting CWL as our workflow standard and what we are building on our team. Questions, comments?

Galaxy is a web-based interactive data analysis platform that supports defining and executing workflows. Galaxy’s workflow format predates CWL and has never been formalized. Instead, new features were continually added, making it difficult to author Galaxy workflows outside of Galaxy’s user interface. Our ongoing work to support the CWL standard has driven the development of new Galaxy functionality and has led to the adoption of open standards and ontologies. CWL support in Galaxy will provide an attractive option for authoring, executing and exploring CWL tools, CWL workflows and their outputs. We also hope that bridging the Galaxy and CWL communities will lead to more opportunities for collaboration among domain-scientists and tool and workflow authors. Questions, comments?

To achieve this, DataPLANT introduces the Annotated Research Context (ARC) which serves as a scaffold for managing research data including metadata as well as computational workflows. However, the availability of multiple metadata standards and more than 300 workflow systems renders workflow FAIRness a difficult task. DataPLANT has selected CWL as their single entry-point to describe workflow metadata, homogenizing the existing landscape. This choice allows to compose executable CWL workflows that are able to integrate other workflow systems. To illustrate the feasibility of integrating arbitrary workflow systems, a CWL workflow was created to execute a processing pipeline designed in Galaxy. This approach autogenerates CWL workflows from Galaxy metadata and is powered by the cwl-ts-auto library using TypeScript. Questions, comments?

Fotiadis Summary: We present experiences from building, CWL usage, and cloudification of the in-silico research platform SilicoFCM, an innovative in-silico clinical trials' solution for the design and functional optimization of whole heart performance and monitoring effectiveness of pharmacological treatment, with the aim to reduce the animal studies and the human clinical trials. The primary aim of the cloudification was to prove portability, improve scalability and reduce a long-term infrastructure costs. The most computationally expensive part of the platform, the asynchronous workflow manager built on top of TOOL, was successfully ported to AWS. We carried out benchmarks on three distinct workflows, each of them having different resource requirements. The first benchmark was pure performance of running workflows sequentially. The aim of the second test was to stress-test the underlying infrastructure by running multiple workflows simultaneously. The results are promising, painting the infrastructure overhead almost negligible in this kind of heavy computational use-case. Questions, comments?

This is enabled by establishing core enabling platforms (clinical genomics, bioinformatics, and health economics). In my lightning talk, I’ll be providing a quick overview of the work undertaken by bioinformatics platform to create efficient, reproducible, and portable workflows. These analysis workflows enable the creation, storage, and investigation of national and global-scale omics dataset via leveraging CWL on Illumina’s Connected Analytics (ICA) platform.

In the original paper (Gabitova-Cornell et al., 2020), analysis of scRNA-Seq data was conducted by manual command line and R processing. However, due to potential changes in tool versions, libraries and execution environments simply repeating the sequence of commands used in processing is likely to produce different results for different users. In order to guarantee the reproducibility and portability of our analytic approach, we converted our analysis into reproducible CWL pipelines and executed them on user-friendly Scientific Data Analysis Platform (SciDAP, https://scidap.com). Open source CWL Pipelines used here are available at https://github.com/Barski-lab/scRNA-Seq-Analysis and https://github.com/datirium/workflows. As a workflow runner we used CWL-Airflow (Kotliar et al., 2019), however, the same pipelines can be executed in any other CWL-based execution environments. For details, refer to the https://doi.org/10.1016/j.xpro.2021.100989 (Surumbayeva, Kotliar et al., 2021). Questions, comments?

We have developed Rcwl, an R interface to CWL, to provide easier development, use and maintenance of CWL pipelines from within R. We have also collected nearly 200 pre-built tools and pipelines in RcwlPipelines, ready to be queried and used by researchers in their own analysis. A single-cell RNA-seq pre-processing pipeline demonstrates use of the software. Questions, comments?

These start with an introductory lesson, teaching core workflow principles, and the basic CWL knowledge required for following these principles. Following this another lesson, covering more advanced workflow techniques and CWL usage will be developed. Each lesson is intended to fit into a 4 hour teaching session - and is intended to be suitable for online or in-person teaching, as well as self-guided learning. The material is being developed inline with Software Carpentry methods, focusing on the biosciences (but hopefully transferable to other domains too). We will be testing the introductory lesson during February for some small group teaching. In this presentation we will talk about the lesson design and material; the choices and compromises we have made in creating the material; what we have learnt from the small group teaching tests, and the future developments that will be made for this material based on these.

Specifically, this presentation focuses on the impact that these rights have on open-source bioinformatics projects within the context of recent decisions determining the scope of patent protection. This presentation then turns to consider how open-source software carries many of the characteristics of a knowledge commons. In particular, this presentation considers how a knowledge commons-based approach to managing open-source software conflicts with many of the conventional approaches to technology transfer. Finally, this presentation concludes by considering what strategies are available to developers to manage the impact of intellectual property rights on open source bioinformatics projects.https://conf.tube/videos/embed/6c353222-4060-4474-8d75-b70e3ec52b58https://conf.tube/w/bBEYxHCtXuECk1Bsn2f5HFhttps://conf.tube/lazy-static/thumbnails/d91f6503-16ea-4bec-a846-d94d1c7494bb.jpgOpenWDL to CWL TranslationPresenter: Dennis Chukwunta Summary: The wdl2cwl converter project is an attempt to efficiently convert workflows written in the workflow description language to an equivalent common workflow language. When executed with the same input, the translated workflow should produce equivalent results to the original workflow. This project leverages on the features of the miniWDL package which is an open source package used to run WDL files locally. The aim of this presentation is to introduce the community to the project and ascertain it’s relevance and importance to the members of the community. Questions, comments?

In the case of workflow executions, we are interested in what outputs were produced, what where the values of the input parameters, which tools were run, how long the execution took, etc. The [CWLProv standard](https://w3id.org/cwl/prov/) provides guidelines to represent such information, but it suffers from interoperability, usability and flexibility problems, and it's only implemented in cwltool. This talk introduces [Workflow Run RO-Crate](https://www.researchobject.org/workflow-run-crate/), a lightweight approach to workflow run provenance that's machine actionable, flexible and interoperable across WMSs. A [software tool](http://www.researchobject.org/runcrate/readme.html) is available to convert CWLProv RO bundles to RO-Crates conforming to the Workflow Run RO-Crate specifications. Support for the format is available in StreamFlow (CWL), Galaxy, COMPSs, WfExS and Sapporo, and is planned to be included in a future release of cwltool. Questions, comments?

CWLProv, a serialization of the Research Object model, is a machine-accessible format for sharing the results of a workflow execution. In addition to the CWL workflow and input and output data for all steps, CWLProv RO Bundles contain a record of the execution (the provenance of the results), encoded in RDF. Here, we assess if the provenance contained in CWLProv is sufficient to address real-life provenance questions, based on a detailed examination of one use case bioinformatics workflow. Distinguishing 5 use cases for ROs associated with the workflow, we define a taxonomy of provenance metadata required to address these scenarios. Subsequently, we assess the CWLProv community standard for the representation of each of the taxonomy components. Based on the results of this analysis, we propose a standard for the annotation of input data, as well as an extension of the provenance graph to enable richer annotations. We are confident that the methodology applied here can be generalized to other workflows and use cases to identify additional provenance requirements, which together with the original provenance taxonomy can inform current and future RO specifications.https://conf.tube/videos/embed/f8ab789c-edbf-45c7-b483-4cd91e5ed7eahttps://conf.tube/w/7riSRwjC8c6iojgdebbWBchttps://conf.tube/lazy-static/thumbnails/0fc49ed3-6d33-4564-adf8-e6e2d249eb8a.jpgDecomprolute: a benchmarking platform designed for multiomic tumor deconvolutionPresenter: [Sara Gosline, PhD](https://orcid.org/0000-0002-6534-4774) (Pacific Northwest National Laboratory) Summary: Tumor deconvolution is a reliable way to disentangle the diverse cell types that comprise solid tumors. To date, however, both the algorithms developed to deconvolve tumor samples, and the gold standard datasets used to assess the algorithms are geared toward the analysis of gene expression (e.g., RNA-seq) rather than protein levels in tumor cells. While gene expression is less expensive to measure, protein levels provide a more accurate view of immune markers. To facilitate the development as well as improve the reproducibility and reusability of multi-omic deconvolution algorithms, we introduce Decomprolute, a Common Workflow Language framework that leverages containerization to compare tumor deconvolution algorithms across multiomic data sets. Decomprolute incorporates the large-scale multiomic data sets produced by the Clinical Proteomic Tumor Analysis Consortium (CPTAC), which include matched mRNA expression and proteomic data from thousands of tumors across multiple cancer types to build a fully open-source, containerized proteogenomic tumor deconvolution benchmarking platform. The platform consists of modular architecture and it comes with well-defined input and output formats at each module. As a result, it is robust and extendable easily with additional algorithms or analyses. The platform is available for access and use at <http://pnnl-compbio.github.io/decomprolute>.

This talk explores the benefits of using a vendor-agnostic workflow language (CWL) coupled with a hybrid workflow management system (StreamFlow) in the HPC ecosystem. Also, it will examine the requirements needed to model HPC applications effectively, the CWL’s readiness to meet such requirements, and the proposals made to improve the language where needed. Four real use cases will drive the discussion: the ACROSS Project (G.A. n. 955648), where CWL is the primary interface to model three HPC workflows, and the EUPEX Project (G.A. n. 101033975), where StreamFlow will be used for the rapid prototyping of a seismic engineering HPC application for a Modular Supercomputing Architecture (MSA) system.

To administer different computational activities in a workflow, different workflow management systems (WMS) are used that necessitate a sophisticated level of standardisation. Standardisation and reproducibility can be achieved by using standard formats for specifying workflows, such as Common Workflow Language (CWL), and provenance gathering with the standard W3C PROV ontology model. During initial stages of workflow design, the FAIR principles, specifically Reusability, are often not followed. And such workflows remain “unmanaged”. Over the years, an increase is observed in metabolomics workflows used to analyze chemical information. To support standardisation and reproducibility in these workflows, we specified and executed the “Metabolome Annotation Workflow” (MAW), which performs chemical structure identification, in CWL and collected provenance using CWLProv to ensure the interoperability and reusability of the workflow. To further improve reproducibility, Docker containers preserving the runtime environment are available for executing the computational activities of the workflow. Questions, comments?

However, like most workflow specifications, it requires the dependencies between all steps forming the directed acyclic graph (DAG) to be explicitly defined. This is not a problem for workflows that consist of a small number of monolithic steps, but for more complex workflows that contain many small steps, the verbosity can become prohibitive. POLUS Workflow Inference Compiler is a YAML-based domain specific language that compiles to CWL which aims to address this shortcoming. It can automatically infer non-ambiguous edges using type and file format matching. Inference is not limited to linear pipelines and can produce an arbitrary DAG. Subworkflows are fully supported, and the inference is guaranteed to work across subworkflow boundaries. Since inference is not always unique, explicit edges are supported with a lightweight syntax. Publication quality GraphViz DAGs are automatically generated. For long running workflow steps (e.g. simulations), realtime analysis is supported via iteratively speculatively executing an arbitrary subworkflow in a separate CWL runner. Automatically inserting missing workflow steps (e.g. file format conversions) is supported via speculatively inserting arbitrary subworkflows between steps from a whitelist at compile time. VSCode IntelliSense code completion is fully supported, and a KNIME-style graphical user interface is in development. Questions, comments?

Schema-salad has two ways of validating a file against a schema (structural validation). It has the default way, which recursively iterates through all keys in the dictionary representation of the YAML/JSON file, and the code generator way, which generates Object Oriented code that creates an object representation of the YAML/JSON object. Schema-salad is used for cwltool to perform validation. The code generator approach is faster but loses line column information and has poor error messages. Improving the code generator approach would allow the code generator to be used in cwltool and reduce the time complexity. Preserving line column information involves changing the way the classes in the code generator approach are created to preserve initial line column information, and modifying the save methods to map the information appropriately. Improving the error messages involves adding hyperlink validation, validating that referenced files exist within a directory, and improving/rewriting validation exceptions. Questions, comments?

Using the schema-salad-tool, a reference tool for SALAD, we can generate code such as data structures and parsers of CWL in various programming languages such as Python, Java, TypeScript, .Net, C++, and D. This talk shows an overview of the CWL parser for D, which has been added since BioHackathon Europe 2022. Unlike the generator for other languages, the schema-salad-tool only generates the data structures, and the parser implementation is automatically deduced from the data structure at compile time by using metaprogramming features in D. It enables us to improve the CWL parsers, such as bug fixes or performance improvements, without re-generating the parsers. Questions, comments?

To support the adoption of BCO as the standard and regulatory submissions for federal agencies, we developed the BCO App, a web application that rapidly generates BCOs. For our examples, we use a publicly available workflow to prepare data for variant calling. The workflow is the public component of an in-progress scientific study that aims to use genetic information to guide cardiovascular disease treatment. We specifically show that the BCO app can generate a BCO from task and workflow information located on either the Cancer Genomics Cloud (CGC) or a JSON file. We then use a custom script that pulls the execution information from the BCO execution domain, allowing for local execution. We include expected results within the BCO error domain, allowing bioinformaticians to verify results from the ported workflow. Questions, comments?

In a recent effort to clarify the overloaded and overused term "workflow" in the context of EBRAINS, especially among users with different (technical/scientific) backgrounds, the need for standardisation in the definition of scentific workflows became apparent. The Common Workflow Language has been adopted as a pilar of this effort, hoping to alleviate the challenges that EBRAINS scientists and users were facing in terms of automated execution and monitoring, as well as portability, scalability and FAIRness. In our presentation, we will depict where EBRAINS was before this approach, what we are moving forward to and what are the next steps.

In the attempt to mitigate some of these problems, we aimed to provide an open and fully interoperable solution that would make most of the benefits provided by state-of-the-art solutions for each of the challenge above. Here we propose WorkflUX, a lightweight and easy to install platform for seamless and user-friendly deployment of scientific workflows to an unlimited set of computational environments. WorkflUX supports interoperable analyses through workflow definition languages, foremost CWL, harnesses portability through containerisation features, scalability is supported by configurable execution backends and intuitive web-based user interface guarantees accessibility to a broad range of researchers.

CWL was and is a principal component of how we orchestrate 1500 years of computation and 80,000 user-created bioinformatics workflows on the Cancer Genomics Cloud, demonstrating CWL’s use as a cloud-based scheduling framework. In this talk, we will select from industry, government, and academic use cases to identify the critical aspect of CWL implementation that empower user success. We also identify pain points we need to get right as a community to facilitate ease of use. Lastly, we will present emerging use cases that might drive a new generation of CWL-driven tools, including automating BioCompute object creation, managing workflow collections, facilitating continuous integration, facilitating bioinformatics training resource development, and automating workflow updates.

We are enhancing REANA's functionality by enabling users to register, execute, and monitor CWL workflows. We are implementing a data provenance capture mechanism for based on the W3C PROV-O standard. Using dynamic placeholders in CWL syntax, our platform emphasises integration with a catalogue of assets, such as AI models, datasets and resources, in order to enable reuse and reproducibility, and encourage scientific collaborations and the sharing of existing resources amongst researchers. Our provenance system for REANA will be made available as part of the European AI-on-Demand platform to meet the needs of AI innovators and researchers for large-scale workflows. Questions, comments?

Yet, CWL workflow specifications are verbose, span multiple files, and are challenging to hold within one's working memory. A workflow language is essentially a means to string together commands in a specific order, and should aspire to the simplicity of a shell script or a Makefile. Higher level workflow languages that compile to CWL can enhance human readability/writability while keeping the hard-won gains of CWL and its standards. Thus CWL would become a kind of assembly language that many different workflow languages compile to. In this talk, I will present the Concise Common Workflow Language (ccwl). ccwl is a workflow language that compiles to CWL. It strives for minimalism, concision of syntax and high-quality compiler error messages. It is currently being used in real-world pangenomics workflows on HPC using toil. I will demonstrate the expressive power of ccwl with illustrative examples. Questions, comments?

How can workflow automation tools, such as CWL and Globus, be leveraged to address these issues and potentially create a new, higher-value form of publication? LivePublication is a system for interfacing reactive, programmatic documents with live computational pipelines - creating a wholistic container that represents data, methods, results, and publications. Using LivePublication, semantic and provenance data are captured and encoded into RO-Crates, forming the basis for programmatic documents that can adapt to changes in results, methods, and custom rules. Repeated execution of the underlying workflow creates an actively updating publication - consistently describing the current state of an experiment. In this way, LivePublication enables a seamless pipeline from instruments, to computation, to publication. Questions, comments?

It leverages the Automated Pipeline Explorer (APE) library to generate workflows in Common Workflow Language (CWL), tailored to user specifications. These workflows undergo a benchmarking process, enabling users to identify the most efficient analysis strategies tailored to their needs. Benchmarking is segmented into two distinct phases: the design-time phase evaluates workflows using pre-execution metrics such as licensing compliance, citation frequency, and compatibility with various operating systems. The run-time phase, in contrast, assesses execution-based performance indicators like memory consumption, processing duration, and error management. To ensure workflows can be executed automatically through cwltool, we include CWL tool descriptions and reference datasets. This approach ensures users can make well-informed decisions, selecting workflows that meet their technical requirements and maximize efficiency. Questions, comments?

The release consists of chemo-informatics tools for integrating cancer treatment features in deep learning graph models. JDACS4C ML models ported to the Cancer Genomics Cloud (CGC) include classifiers, autoencoders, drug response predictors, and Multitask Convolutional Neural Networks. The porting of these tools to CWL on the CGC will allow for lower barriers to entry for new users who aim to use machine learning-driven drug discovery, as well as streamline the development process for more technical users. The accessibility and adaptability of these MoDaC toolsets will allow for the optimization of the drug discovery pipeline by supporting pre-clinical study evaluation, treatment identification, and experimental design.https://conf.tube/videos/embed/e86988e6-576e-4f7f-a2ce-68b19e35a5cdhttps://conf.tube/w/rKz7jfzMJfEKcEcYH1E7Dxhttps://conf.tube/lazy-static/thumbnails/0869c87e-3769-49fd-9a7e-85190d5d95aa.jpgExtending CWL for High-Performance Computing: A Visual Workflow System with HPC EnhancementsPresenter: Zhang Yexi Summary: In this presentation, we delve into our cutting-edge development: a visualization workflow editor and submission system based on the Common Workflow Language (CWL), with a special focus on our extensions tailored for High-Performance Computing (HPC) environments.

Public genomic data often undergo similar preprocessing across projects, leading to redundant or inconsistent datasets and inefficient use of computing resources. This is especially pertinent for bioinformaticians engaged in multiple projects. Here we present ReUseData, an R software tool that overcomes some of the limitations of existing solutions and provides a versatile and reproducible approach to effective data management within R. ReUseData facilitates the transformation of ad hoc scripts for data preprocessing into Common Workflow Language (CWL)-based data recipes, allowing for the reproducible generation of curated data files in their generic formats. The data recipes are standardized and self-contained, enabling them to be easily portable and reproducible across various computing platforms. ReUseData also streamlines the reuse of curated data files and their integration into downstream analysis tools and workflows with different frameworks. Questions, comments?

Results are derived from data with code, and to understand and scrutinize them requires that data and code can be brought together in a predictable, repeatable way with minimal effort. At the Swiss Data Science Center we are building Renku, an open source platform focused on enhancing transparency, collaboration, and reproducibility in all types of data-centric research. In Renku, researchers can combine sources of data and code with containerized computational environments in a well-documented way for everything from day-to-day work to dissemination, demonstration, and publication. The use of data can be self-consistently tracked and indexed in a knowledge graph for search, discovery, and audit. In this contribution, we will summarize the design and features of the platform. We will dedicate specific focus to the role that workflow tools, like CWL, play in such an ecosystem and how they can be leveraged to improve FAIR-ness and sustainability of data science projects.

Then we center around the main research question: How do we achieve a highly automated FL process while supporting diverse FL scenarios? We proposed our solution to this question. We introduce a novel CWL-based method, named CWL_FLOps, that leverages common workflow language to automate the federated learning operations at scale and present the evaluation process.

These languages delineate the tasks to be executed, their interrelations, and facilitate their enactment through specialized engines. Nonetheless, the landscape of existing applications in this sphere reveals considerable challenges, predominantly attributed to the platform-specific nature of current workflow languages. This constraint limits their interoperability and the reuse of generated knowledge across various systems. In response to these challenges, SWEL (Scientific Workflow Execution Language) emerges as a domain-specific language founded on the precepts of model-driven engineering. It is an abstract language, formalized in an extensible and concrete syntax-independent manner. Conceived to encapsulate both high- and low-level characteristics of data-intensive workflows, SWEL is distinguished by its platform independence and its potential for collaboration among data scientists from various fields. Its architecture facilitates interoperability, the adaptation to existing support technologies, thereby enhancing the utility and flexibility of workflow management systems and the completion of its specification. SWEL integrates all elements of the Common Workflow Language (CWL). However, it also presents a supplementary viewpoint for the community, advocating a broader, more adaptable approach to the development and execution of scientific workflows in data-rich industrial settings.

NGS360 integrates with Arvados, SevenBridges/Velsera, and AWS HealthOmics to run CWL workflows. Using an orchestration framework called the Launcher and the Platform API Middle Layer, analysts can develop CWL based workflows that can seamlessly run across CWL execution engines with minimal effort. As such, NGS360 has become the de facto platform for BMS for managing NGS data and running CWL workflows. Questions, comments?

Those tasked with data collection and curation assume a collector role. Adding to some of these, others assume an analyst role. And many, perhaps a vast majority, of those who rely on scientific research never themselves enter the lab or analyze the results on which they depend. CWL workflows simplify this separation of concerns. They allow analysts to access and use data without placing an additional demand on collectors, and they allow application developers--and therefore, consumers--to use the results of analyses without placing an additional demand on the analysts. We will present examples of a CWL-backed framework that spans the data lifecycle from collection through analysis, service creation, and application deployment.https://conf.tube/videos/embed/ca3c2f61-7632-47eb-afb2-76082f93297dhttps://conf.tube/w/4jwkPH7Z5MzSKziUkqZ7yuhttps://conf.tube/lazy-static/thumbnails/88423965-67ca-4d8f-8bdb-0310b8926833.jpgJSON Schemas for validating CWL and CWL InputsPresenter: Alexis Lucattini Summary: How do you know if your inputs for a CWL workflow are valid without just running the workflow? If you have access to your workflow, ‘cwltool –validate workflow.cwl input.json’ might be enough, what if you don't have easy access to the underlying workflow object? What if you are submitting your input json to an API endpoint to run an analysis? What if your workflow engine doesn’t validate your inputs before downloading terabytes of inputs? Only to fail hours later :( This could have been prevented if there was a JSON schema for the CWL workflow. In this talk, we explore the benefits and challenges of JSON schemas, how we’re using JSON schemas for CWL workflows at UMCCR. We also explore JSON Schema as a benefit for developers of CWL Workflows, since workflows themselves can be represented as JSON objects with their own requirements. Questions, comments?

It discussed WES's similarity to platforms like Galaxy and its emphasis on workflow orientation. Developed with GA4GH standards, WES ensures reproducibility and enables the "code-to-data" approach for sensitive data protection. Sapporo, an implementation of WES, was presented as a portable, lightweight system supporting multiple workflow languages. Tools like Yevis and Tonkaz were introduced to enhance security and reproducibility. Yevis facilitates workflow registry maintenance, while Tonkaz compares workflow runs for consistency. The talk highlighted the importance of comparing workflow logs and output files for reproducibility assurance. Overall, the presentation emphasized WES's significance in large-scale data analysis and introduced tools for workflow management and validation. Questions, comments?

In this talk, we identify several challenges that these workflows cause to traditional workflow systems based on the analysis of five generic workflow motifs originating from diverse scientific domains. We also express some opportunities to develop a modern workflow ecosystem should to efficiently drive workflows for their data plane. Questions, comments?

The adoption of Rust not only improves security and performance in data manipulation, but also opens up new perspectives for the development of complex workflows through efficient memory management and strong typing. The core of this extension is to provide developers with the tools to build robust, high-performance applications that can handle data flows more securely and efficiently. We will discuss how a Rust API can help the CWL community, allowing developers to build faster, safer, and more reliable workflow systems. All the code will be made public on GitHub and on Crates.io, the Rust community's crate registry. Questions, comments?

The talk starts by discussing the process of introducing new features for CWL, then discusses several extensions and proposals that are already in progress, including “overrides”, “CUDARequirement”, handling credentials as “secret” inputs, loops, and input constraints. The talk then discusses developments in tools that generate CWL from alternative workflow languages and how to formalize support for code generation as a CWL feature. The talk concludes with discussion of design mistakes in CWL that we are aware of and hope to address in future revisions, including requirements inheritance, input/output parameter name conflicts, and behavior of shell command requirement.

Since it was first released in 2001, it has been instrumental in teaching coding to students, artists, and designers worldwide, serving as a gateway into programming for people who might never have touched code otherwise. A remarkable thing about Processing is the consistency of its API. Most Processing code written twenty years ago still runs in Processing today with only minor changes. That kind of longevity is rare in software and speaks to the project's thoughtful design. But behind the scenes, the project has been struggling. For a long time, Processing relied on a small, dedicated core team. As contributors moved on, fewer people remained who understood the full complexity of the codebase. Maintenance became harder. Key libraries stopped working. By the time Processing 4 was released, the project was already in a difficult place. In 2021, a major fundraiser for Processing’s 20th anniversary brought unprecedented financial support, but it also sparked difficult conversations about the project’s future. In 2023, Processing’s historical maintainer, Ben Fry, cut ties with the project, and with no clear direction, development stalled for over a year. Many assumed Processing was dead. It is not. That same support that brought uncertainty also made recovery possible. Over the past year, a small group of contributors, with support from the Processing Foundation, has restarted development, modernized infrastructure, and begun the slow, difficult work of making Processing a sustainable open-source project again. Processing will turn 25 in 2026, and we’re working to make it last for another 25 years! This talk is an honest look at what it takes to keep a beloved open-source project alive, the progress we’ve made, and why the community’s role in its future is more critical than ever.

This session explores two distinct scenarios where bitmap fonts have a role to play and looks at the tooling needed to convert or repackage older bitmap formats for convenient usage in modern free-software applications. The first scenario is enabling vintage computing aesthetics in graphic design: there are several paths available to transform bitmap fonts into forms usable in Inkscape, GIMP, and other open-source design tools. The second scenario is getting text onto inexpensive LCD, LED, and OLED display hardware. Most such display hardware allows the runtime loading or flashing of bitmap characters, but pitfalls abound. Options and recommendations for both scenarios will be examined, with demos drawn from vintage arcade fonts and the classic Xorg/X11 font suite. To conclude, the talk will outline the licensing issues likely to arise when dealing with bitmap font packages that so often predate contemporary free-software licenses.

This project enabled a complete “RE:imagination” of the UpStage code, removing its dependency on Flash, introducing new features and bringing it up to date with current technologies. The last time we presented UpStage at LGM, in 2021, we had just begun this process; since then, the new platform has been launched and development is ongoing. In this presentation, our Lead Developer Gloria W. and UpStage Persister Helen Varley Jamieson will present the new platform and its features including its integration of Jitsi for audio-visual streams, audience interaction and live text and drawing tools. Most recently the developers have implemented Docker and made other improvements to the backend, to make installation of independent instances easier and testing more automated. Alongside the development work, UpStage continues to actively promote the use of open source tools by artists, and the involvement of artists in the development of our digital tools. This is ever more important as LLM (so-called AI) and the increasing hegemony of proprietary social and creative platforms force artists into their paradigms. UpStage continues to be an independent, artist-led space for the “RE:imagination” of better worlds. ## Links * [UpStage](https://upstage.org.nz/) * [UpStage: the cyberformance platform](https://upstage.live/) * [Mobilise/Demobilise](https://mobilise-demobilise.eu/) Licensed to the public under https://creativecommons.org/licenses/by/4.0/https://conf.tube/videos/embed/050b2dc8-211f-45e3-9b3e-268984009daehttps://conf.tube/w/pVAAHkge1tstHPMJKa85GZhttps://conf.tube/lazy-static/thumbnails/c3063dd4-bc1d-4204-8979-373327b06b5e.jpgLGM 2025 - The Curious Case of Splines in FreeCADSplines, especially in their general form as NURBS, are an extremely versatile tool in a 3D designer's kit. They allow the designer to succinctly and efficiently model objects of arbitrary shape and smoothness. For converting these designs into physical objects, FreeCAD has a vast set of tools to operate on NURBS, both as planar curves and (with addons) as surfaces. However, the complications of NURBS can also cause a good amount of confusion, especially compared to other representations of splines, which may be more familiar to the user from other applications (which may include other CAE apps as well as more artistic tools like Inkscape). In this talk, I discuss some of these common questions often seen in the issue tracker and forums, as well as best practices to follow for common workflows. I also showcase current progress and future plans to make the experience more intuitive and in line with other apps.

Beyond that, something that once promised a utopian future now feels like it has delivered a rather crappy, disappointing reality. FLOSS has undoubtedly played some role in this development, but it also holds a great potential as part of a shift in imagination to new practices and aesthetics that are more verdant, just and humane. This presentation will propose the concept of "Permacomputing" as a useful lens to consider the role of FLOSS in developing alternative practices. Permacomputing is both a concept and a community of practice oriented around issues of resilience and regenerativity in computer and network technology inspired by permaculture. We will start with a brief introduction to the concepts and emerging projects around these ideas. With these notions in mind, we can then examine how some of the existing practices of Libre Graphics might inspire or give relevant support to newer, more holistic ways of working. And finally, we will look at some specific examples of software development, education and image making using the generative flora of computing within limits.

Their needs for video editing solutions are diverse, and so is their budget. Open-source video editing software seems great for beginners to get started at zero cost. What do you get and what do you have to give up on compared to the closed-source options? What does it even take to build software like this from scratch, technologically as well as mentally? This talk takes a brief look at the free-to-use options for video editing on a desktop computer before switching the perspective to that of the developers and maintainers of such software. It offers insights into the struggles with technology, fundraising, self-motivation, and community dynamics, while also highlighting the rewarding moments and intriguing current and future developments.

Ten years later, however, there now is a strong Free Software option for designing your own PCBs and there is a growing community of artists using PCBs as a medium for artistic expression, a lot of them actually using KiCAD for the design work. I want to showcase examples of PCBs where the properties of PCBs are used to create visually appealing hardware. I'll also give a quick tour through KiCAD to show the limits of its capabilities as well as its strong side for graphical artworks.

Everyone use it everyday for many purposes. In this context, many software can produce PDF. Still, as graphic designers, we must often deal with provided PDF that doesn’t match our needs, because one PDF isn’t worth another. On the other side, printshops also come with their own standards and constraints. How can we deal with theses everyday outcomes and be sure our PDF will match the delivery standards, using only free softwares? In this presentation, we will talk about several PDF tools trying to reach this goal of giving the right PDF to the right person.

It uses a file-based, modular building block system for authoring video sites ranging from single videos, to playlists, to video collections of arbitrary hierarchical complexity. Sites can be created and edited using Hyper 8's graphical user interface, but also using nothing more than a terminal, file explorer and text editor (or both). Due to their static nature, Hyper 8 sites are inherently fast, maintenance-free, long-term archivable (also working offline without a server, directly off disk) and compatible with pretty much every webhost (thereby easy to publish and move). In this talk I want to take you on a whirlwind tour around the project: Who is this for? What was the motivation? How does this relate to PeerTube? What is being developed at the moment? Where is it going in the future? What are the challenges, learnings, anecdotes so far? And so on. And of course also: Your questions!

It is now fully integrated in Blender 3D, which is using an extended version of the gltf format. An extension allows you to attach all the basic components to objects, like particles, UV animations, water and much more. But you can also share links, videos and audio right inside your 3D rooms. Soon another feature was added to the gtlf exporter, the Behavior Graph. It enables interactivity via node-based logic and is only available in Blender 3D. It is the very feature we would like to present to you. If you are used to Blender’s nodes graphs, you might feel right at home. However managing interactivity creates a distinct difference, since every node needs to get triggered by events, be it player interaction or just timer based.

Inspired by a variety of waterfalls in the Pacific Northwest of the USA, Tom has been playing around with different ways to create waterfalls in the open source Godot game engine, with the help of other open source software such as Blender, Krita, and Gimp. Video game fluid flow is a complex subject, and this talk will outline various methods to cheat so that you don't really have to know complex math to make something acceptable.

After having laid out the foundation, a brief overview of different usability evaluation methods is given. The main part of the presentation is about introducing two often used methods: On the one hand the heuristic evaluation as an example of a usability inspection method, and usability testing on the other hand. Both methods can be used to find (potential) usability problems in a software. Whereas a heuristic evaluation is conducted by an expert following a check-list, a usability test needs end users who fulfill tasks to be conducted. After describing how both methods can be used individually, also a practical way to combining them is presented. The session will conclude with an overview of the advantages and disadvantages of each method. Three takeaways of this session will be: * A basic awareness for usability/UX and the importance of evaluating it * An overview of the two major usability/UX evaluation methods heuristic evaluation and usability testing * A first idea how to use these methods for your/a software project Target group * UX/usability laymen * Contributors to software Licensed to the public under https://creativecommons.org/licenses/by/4.0/https://conf.tube/videos/embed/966c04c8-0caa-4d5b-a2e3-b2329d830ed0https://conf.tube/w/5ELQmRdn5cnx2pLW6WqB9dhttps://conf.tube/lazy-static/thumbnails/0040a293-3846-482c-b283-ac4500a8289c.jpgLGM 2025 - 3000 % FasterFile Saving With Time TravelA developer talk about coming up with a new file format for [Drawpile](https://drawpile.net/) with the focus being on the findings and ideas that would be useful for other programs as well. Some of those ideas are already implemented and have brought a massive speedup in file saving and loading, some wilder ideas like continuous autosave with history-altering time-travel are in various states of currently still being worked on, but sufficiently cool to talk about anyway.

What can we learn from these languages from current graphic practices and perspectives? What context were these languages developed in? Which aesthetics can be created with them today and which tools are needed to do so? How can the sharing culture of the FLOSS/LGM community be applied to such old "closed source" devices? This artistic, media archeological, and auto-ethnographic research is part of the Master Experimental Publishing (XPUB) in Rotterdam, where we, students and teachers, studied these languages together in the first 3 months of this year on the most obsolete and almost discarded printing devices of our university. Expect a presentation about frustrations with serial connections, dust removal with compressed air, porous plastic that disintegrates into small pieces, glitch aesthetic with PostScript and the practice of working within the obstacles of dying devices. Watch out for undead pen plotters & printers and their obscure languages!

At previous LGMs we’ve talked about open-source design feeding back into improving the look, feel and usability of creative software. But what about the tools used to write those tools? Can we link things back another step? Coding environments have barely changed in decades. Yet the complexity of software produced in them has risen exponentially. The disconnect from cause to effect has become ever greater. All software has bugs, most bugs involve software doing exactly what it was told to do. Sometimes they eat your work, sometimes they kill people. The title of this talk is partly “borrowed” from an article that appeared in The Atlantic in 2017. But is it all hyperbole? This talk was originally proposed for the cancelled LGM in 2020 - the landscape may have evolved since then, such as in the growth of AI, but has it improved? Let’s consider some of the issues. And ongoing experiments in user interaction, liveness and design in various open-source tools that are seeking to change coding for the better. This talk may cover some of the ideas in play. But it certainly won’t have the right answers. It probably hasn’t even found the right questions. But just maybe it’s time to help save the world from code.

A happy-ending story about finding out the tips and tricks along the way. Last November, we've been comissioned to produce a small series of printed maps for a cultural center in Lessines, Belgium, to celebrate memories of Louis Scutenaire and René Magritte. We aimed for a project using three colors, and decided to go for spot color printing - using libre graphics tools, mainly QGIS for the design of the map, and Scribus for layout elements and to prepare the pdfs for printing. We also used Inkscape to vectorize some small illustrations, as well as Ghostscript to check and sometimes fix the resulting PDFs. Then, once we decided that it would be spot color printing, we had to find out a workflow from QGIS to Scribus in order to produce PDFs for spot-color printing. It was not without a few obstacles that we encountered, as both QGIS and Scribus present limitations in terms of color processing or vector rendering. We will present our productive investigation into both QGIS and Scribus, describe how we use QGIS functionalities to optimize the maps for spot color printing and show the tips and tricks we learned along the way - and share the results, hoping to inspire other mapmakers around to give it a try.

It provides type proofing applications, initially based on Video Proof and Variable Type Tools. Now it also explores the world of general animation with type as a principal actor, and document creation with general typography in mind and typographical automations based on expert knowledge. TypeRoof is **intended as a host** for all kinds of type related tools, providing advanced methods of resource loading (i.e. fonts, data files) saving and restoring state etc. – features which ad-hoc developed tools typically miss out, as they are hard to do right on limited time. TypeRoof is **Free/Libre Open Source Software and web based**, build mainly with vanilla JavaScript and a few specialized dependencies. We are looking for a community of users and developers who are interested in shaping its future.

It is more durable than other customization methods for textiles and it adds a whole new artistic dimension to the design. What makes it so beautiful, also adds a new layer of complexity to the machine embroidery design creation process. In this brief introduction we will learn a few basic essentials on how to create machine embroidery designs using the Open Source vector graphic software Inkscape along with the Ink/Stitch extension.
