<p>foss-north is a free / open source conference covering both software and hardware from the technical perspective. Hosted in Gothenburg between Copenhagen, Oslo and Stockholm with an international airport, we provide a meeting place for the Nordic foss communities and will bring together great speakers with a great audience.</p><p>&nbsp;</p><div class="container"><h1>Speakers and Talks</h1><div class="bodybreak">&nbsp;</div><a name="paas" class="offsetanchor"></a><div class="row"><div class="col-md-3"><div class="picture"><img src="http://foss-north.se/2018/images/speaker-paas.jpeg" alt="Patricia Aas" class="sp-image"></div></div><div class="col-md-9"><div class="name">Patricia Aas</div><div class="title">Isolating GPU access in its own process</div><div class="abstract">Chromium's process architecture has graphics access restricted to a separate GPU-process. There are several reasons why this could make sense, three common ones are: Security, Robustness and Dependency Separation.</div><div class="abstract">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.</div><div class="bio">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. Patricia is a curious person, always trying to find out how things work. She hopes that we will find a way to make the world a better place by creating things that can be used for good.</div></div></div><div class="bodybreak">&nbsp;</div><a name="padams" class="offsetanchor"></a><div class="row"><div class="col-md-3"><div class="picture"><img src="http://foss-north.se/2018/images/speaker-padams.jpeg" alt="Paul Adams" class="sp-image"></div></div><div class="col-md-9"><div class="name">Paul Adams</div><div class="title">The Art of the Pull Request</div><div class="abstract">Take a moment to ask yourself, "what are Pull Requests for?"</div><div class="abstract">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?</div><div class="abstract">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.</div><div class="abstract">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.</div><div class="bio">Paul Adams is the Open Source Lead for Europe's largest e-commerce platform, Zalando. Paul works in support of a team that helps to grow a community around Zalando's open source technologies and to consult internally on how best to operate in an open manner. Paul is known as a long-time contributor to the KDE community but these days, spends most of his contribution time working on Habitat.</div></div></div><div class="bodybreak">&nbsp;</div><a name="mbergek" class="offsetanchor"></a><div class="row"><div class="col-md-3"><div class="picture"><img src="http://foss-north.se/2018/images/speaker-mbergek.jpeg" alt="Martin Bergek" class="sp-image"></div></div><div class="col-md-9"><div class="name">Martin Bergek</div><div class="title">Monitor everything from physical hardware to application functionality</div><div class="abstract">The IT industry is a diverse and dynamic world where applications and functions may be spread out - and move between a multitude of providers and technologies such as Amazon AWS, Rackspace, KVM, volatile containers, and your internal traditional IT infrastructure with physical servers.</div><div class="abstract">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.</div><div class="abstract">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.</div><div class="bio">OP5 is a built on Open Source and has been a active player in the Open Source monitoring world since it was founded in 2004.

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.</div><div class="abstract">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</div><div class="abstract">In this talk, Jakob will cover Khronos' OpenXR standard, give an overview about the current state of open source VR and what lies ahead.</div><div class="bio">Jakob is a former student of Chalmers now working for Collabora with graphics and virtual reality.

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.</div><div class="abstract">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.

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).</div><div class="abstract">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.</div><div class="abstract">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.</div><div class="abstract">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.</div><div class="bio">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.

Improving software review and QA with diffoscope</div><div class="abstract">In 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.</div><div class="abstract">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…!</div><div class="abstract">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.

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.</div><div class="bio">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.</div><div class="bio">Vincent currently works as software developer at the IT department of University Paris 1 Panthéon-Sorbonne. He develops and deploys web applications related to student management, mainly using Java, Oracle Database and MySQL.</div></div></div><div class="bodybreak">&nbsp;</div><a name="iszmozsanszky" class="offsetanchor"></a><div class="row"><div class="col-md-3"><div class="picture"><img src="http://foss-north.se/2018/images/speaker-iszmozsanszky.jpeg" alt="Istvan Szmozsanszky" class="sp-image"></div></div><div class="col-md-9"><div class="name">Istvan Szmozsanszky</div><div class="title">Mozilla and AV1 - using the browser to develop a royalty-free, open-source video codec</div><div class="abstract">The first thing that jumps to one's mind when someone mentions "pooling" in the context of media codecs is usually patents. 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.</div><div class="abstract">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.</div><div class="bio">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. He loves to dig deep into JavaScript language and engine internals and playing (quite literally!) with hardware and microcontrollers.</div></div></div></div>
