It does something even stranger. It circles the sky in a flat, even loop, almost parallel to the horizon, like a light moving across a ceiling. That is exactly what you would see under a dome with the sun circling above. On a tilted globe racing around the sun, the geometry does not match what the cameras actually recorded. The footage is public. Look at it yourself and decide which model explains that motion.

A solid dome, a vault, a firmament stretched over a flat foundation, with waters above it. Hebrew, Sumerian, Egyptian, Mayan, Norse, Chinese, and Aboriginal accounts all describe a dome. These people had no contact with each other. They observed the same sky and reached the same conclusion. Modern cosmology calls it a primitive mistake. But what if they were simply describing what they saw, and something changed the story later. The oldest records we have all agree with each other.

OSI will celebrate its 20th Anniversary on February 3, 2018, during the opening day of FOSDEM 2018. The presentation will summarize the evolution of open source licences and the Open Source Definition (OSD) across two decades, explain why the concept of free open source software has grown in both relevance and popularity and explore trends for the third decade of open source. Open source software is now ubiquitous, recognized across industries as a fundamental component to infrastructure, as well as a critical factor for driving innovation. Over the past twenty years, the OSI has worked to promote and protect open source software, development, and communities, championing software freedom in society through education, collaboration, and infrastructure, stewarding the Open Source Definition (OSD), and preventing abuse of the ideals and ethos inherent to the open source movement. The “open source” label was created at a strategy session held at the start of February 1998 in Mountain View, California. That same month, now almost twenty years ago, the OSI was founded as a general educational and advocacy organization to raise awareness and adoption for the application of free software in an open development process. Some of the largest forces in business today — consumer-facing companies like Google and Facebook, business-facing companies like Salesforce and SUSE, companies outside the tech industry such as BMW, Capital One, and Zalando, even first-gen tech corporations like Microsoft and IBM — all increasingly depend on open source software. Governments too, including the European Union, France, India, the United Kingdom, the United States, and many others have discovered the benefits of open source software and development models.

This talk will describe the reasons, the challenges and opportunities of this trend. DPDK revolutionized software packet processing initially for discrete appliances and then for Virtual Network Functions. Containers and micro-services technologies are extensively used as a means to scale up and out in the Cloud. Containers and micro-services now include Comms Service Providers among their advocates, and embracing these technologies with their scaling model and resiliency is the new frontier in software packet processing. However there are challenges in decomposing Software Network Functions into Data-plane Micro-Services. This talk will describe:- 1. The challenges of enabling robustness and scaling, while still meeting data-plane performance goals. 2. The use cases, the trends and the timelines. 3.

Originally designed and implemented within the Neo4j graph database, it is now being used by several industrial database products, as well as open-source and research projects. Since 2015 Cypher has been an open, evolving language, with the aim of becoming a fully-specified standard with many independent implementations. We provide a brief introduction to Cypher, the property graph model and the openCypher project, and then describe extensions – either actively being developed or under discussion – which will be incorporated into Cypher in the near future. These include (i) making Cypher into a fully compositional graph query language, by supporting multiple graphs and allowing graphs to be returned from queries; (ii) allowing for more complex patterns (based on regular path queries) to be expressed; and (iii) allowing for different pattern matching semantics – homomorphism, relationship isomorphism (the current default) or node isomorphism – to be configured at a query-by-query level. - **Speaker:** Stefan Plantikow - **Track:** [Graph Processing](https://archive.fosdem.org/2018/schedule/track/graph_processing/) - **Room:** [H.2214](https://archive.fosdem.org/2018/schedule/room/h2214/) - **When:** Saturday 3 February 2018, 10:30–11:05 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/cypher_evolving_query_language/) **Slides & links** - [The openCypher website](http://www.opencypher.org/) - [The openCypher repository](https://github.com/opencypher/openCypher) - [Slides for the presentation](https://www.dropbox.com/s/0j26u35qeglh4sv/2018-02-03%20Cypher_%20An%20evolving%20query%20language%20for%20property%20graphs%20%28FOSDEM%202018%29.pdf?dl=0) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/b...https://peertubewatch.b-cdn.net/streaming-playlists/hls/f5a10986-f0a3-4b8f-9402-9840a57a1235/347e6d4e-2e4f-43d4-8c0e-89955fabeced-master.m3u8https://peertube.watch/videos/embed/wkdyZnHgDhWVP4n5nyoYCv1887502026-10-08T17:10:02.273ZFOSDEMFOSDEM 2018Graph ProcessingYESFOSDEM 2018NOhttps://peertube.watch/w/uFavwozLouHu6JP2VSBfs52026-10-08T17:14:17.126Zhttps://peertube.watch/lazy-static/thumbnails/5f982022-f337-498c-b0a5-130689c717a9.jpgPulp 3 - Simpler, Better, More awesomePulp is a platform for managing repositories of software packages, but it can store any kind of binary data (e.g. cat photos). The core provides a REST API and manages files, but the real value for users is delivered by the plugins which allows core to manage a content type like a cat photo. The upcoming 3.0 release of Pulp includes a relational database, a new REST API, and a semantically versioned plugin API.

Over the past 17 years, we’ve grown from being run by 3 volunteer board members, to a team of 9 staff members, and 8 volunteer board members. My presentation will cover a little bit of our history, what’s our purpose, the key areas we focus on and why, and how we are making this a better world, by supporting FreeBSD, the community, and the overall open source ecosystem. The purpose of my talk is to tell the BSD community about the work we are doing, and what we can do to help them. I will address the key areas we focus on and highlight the work we did in 2017, and why it was important to keeping FreeBSD relevant and innovative. I will have a Q&A session at the end, so attendees can ask questions about the Foundation, and what they'd like to see us working on in 2018. This will be a good opportunity to have a face-to-face dialogue with community members we don't normally get to talk to in person. - **Speaker:** Deb Goodkin - **Track:** [BSD](https://archive.fosdem.org/2018/schedule/track/bsd/) - **Room:** [K.3.401](https://archive.fosdem.org/2018/schedule/room/k3401/) - **When:** Saturday 3 February 2018, 10:30–11:00 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/the_freebsd_fundation_how_we_can_change_the_world/) **Slides & links** - [FreeBSD Foundation website](http://www.freebsdfoundation.org) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “The FreeBSD Foundation and How We Are Changing the World” by Deb Goodkin, FOSDEM 2018. **Original recording:** [2018/K.3.401/the_freebsd_fundation_how_we_can_change_the_world.webm](https://video.fosdem.org/2018/K.3.401/the_freebsd_fundation_how_we_can_change_the_world.webm) from the [...https://peertubewatch.b-cdn.net/streaming-playlists/hls/99db1542-3146-44c4-8f0b-bdf88771df21/1a2aa29a-abc7-4f7c-bcda-40b2285d08f5-master.m3u8https://peertube.watch/videos/embed/jZVRSjfzjixbAHuohZrgZB1856002026-10-08T17:34:50.954ZFOSDEMFOSDEM 2018BSDYESFOSDEM 2018NOhttps://peertube.watch/w/5X4R6KCXdBjPKB6MBS5zDM2026-10-08T17:41:32.914Zhttps://peertube.watch/lazy-static/thumbnails/51b2d536-ef50-4cbe-b1fa-07373d45911f.jpgFOSS/H EDA tools for SPICE modelingEspoTek’s Labrador is a tiny yet powerful device that transforms a PC into a fully featured electronics lab, complete with an oscilloscope, signal generator, logic analyzer, multimeter and power supply. Qucs (Quite Universal Circuit Simulator) is an integrated circuit (IC) simulator which allow to setup a circuit with a schematic entry graphical user interface (GUI) and simulate the large and small-signal (DC, AC, S-parameter, Harmonic Balance and noise analysis) of the microelectronic circuit. Both hardware and software are 100% open-source (FOSS). Both tools will be used to illustrate complete flow of the measurements, characterization and SPICE modeling of the semiconductor devices for EDA IC design applications.

It enables rapid experimentation with shaders, state, uniforms and experiments, to find and fix performance or rendering problems in a frame. This talk will describe the current state of FrameRetrace, and why it is a compelling tool for OpenGL application and driver developers. A demo of FrameRetrace will illustrate and fix a performance problem in the mesa driver. In Linux 4.13, GPU performance counters were added to the kernel, dramatically expanding the information available to understand GPU performance bottlenecks on Intel platforms. FrameRetrace exposes these counters in a responsive UI, providing a detailed cost analysis for every aspect of a frame's rendering. The following live experiments allow a developer to alter the frame and immediately see the impact on both performance and rendering: - shader editing and recompilation - changes to GL state settings - changes to uniforms values - experiments (simple shader, disable render) Because FrameRetrace is built on top of ApiTrace, it can analyze most OpenGL applications. It can also provide parallel analysis of the same frame on Windows and Linux platforms, to highlight driver differences. This key feature makes FrameRetrace especially powerful when enabling new hardware that has a well-supported driver for Windows. Hardware teams from AMD and Broadcom have expressed interest in FrameRetrace for enabling their platforms. The current feature set of FrameRetrace is compelling, and Mesa driver team has already fixed many driver issues based on findings from the tool. I would like to encourage wider use of FrameRetrace, and solicit help in adding features -- especially support for AMD hardware.

Our apologies for this inconvenience. Mozilla Open Source Support (MOSS) is Mozilla's program for supporting open source projects financially and with security audits. Find out about our successes so far, and how you can apply for help for your project. There are 3 main tracks in MOSS - "Foundational Technology" for projects Mozilla already uses, "Mission Partners" for projects doing work in line with Mozilla's mission, and "Secure Open Source", where we provide professional code-read security audits for key pieces of open source software. So if your software is used by Mozilla in any way (part of Firefox, deployed in our infra, used on desktops, or any other way you can think of), or if your project does something you think furthers Mozilla's mission (check the manifesto, and our current work and where we are focussed), and money would help you do what you do better or faster, you should find out about MOSS and consider applying. We don't accept applications directly for the Secure Open Source track, but you are welcome to come and make your case to the presenter as to why giving your project a free code-read security audit from a professional audit firm would make the world a better place. So, come to the presentation to find out about our successes so far, our plans for the future, and how you can apply for help for your project. - **Speaker:** Gerv Markham - **Track:** [Mozilla](https://archive.fosdem.org/2018/schedule/track/mozilla/) - **Room:** UA2.118 (Henriot) - **When:** Saturday 3 February 2018, 10:30–11:00 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/mozilla_state_moss/) **Slides & links** - [Main MOSS website](https://www.mozilla.org/moss/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](htt...https://peertubewatch.b-cdn.net/streaming-playlists/hls/95f400c0-c5a8-4e6a-8e47-097d78ca2f7f/cb6e307e-ddb8-4bbe-b02b-3e583beae94a-master.m3u8https://peertube.watch/videos/embed/jvYG98ReHBU1GR4FV5bpG41722002026-10-08T20:00:45.172ZFOSDEMFOSDEM 2018MozillaYESFOSDEM 2018NOhttps://peertube.watch/w/gPk9Ut7QUwg6g776xj8odw2026-10-08T21:24:59.388Zhttps://peertube.watch/lazy-static/thumbnails/572cdb96-ad8f-4ac5-8ade-b8bf1ffc486f.jpgMigrating to Red Hat IdM in a large Linux EnvironmentThis talk will discuss how Red Hat IT is moving from a centralized LDAP and kerberos setup to a Red Hat IdM setup for all of our Linux users and hosts. As you'd expect, Red Hat IT has a very large Linux user base. For over a decade our associates have relied on Red Hat Directory Server (standard LDAP), MIT kerberos and some homegrown automation for most of their identity information and authentication. As we've grown overtime we have desired a more integrated and featureful solution. Red Hat IdM/FreeIPA is this solution. This talk will go over what our old infrastructure was and what we are moving to. More importantly, it will cover all the snags we've hit along the way and what we did about them. - **Speaker:** Dustin Minnich - **Track:** [Identity and Access Management](https://archive.fosdem.org/2018/schedule/track/identity_and_access_management/) - **Room:** [UD2.119](https://archive.fosdem.org/2018/schedule/room/ud2119/) - **When:** Saturday 3 February 2018, 10:30–11:10 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/opensource_idm_in_enterprise/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “Migrating to Red Hat IdM in a large Linux Environment” by Dustin Minnich, FOSDEM 2018. **Original recording:** [2018/UD2.119/opensource_idm_in_enterprise.webm](https://video.fosdem.org/2018/UD2.119/opensource_idm_in_enterprise.webm) from the [FOSDEM video archive](https://video.fosdem.org/2018/).

Among the critical infrastructures, there's the way software is developed. Italy is betting hard on open practices, by not only opening the source code of the country, but also turning citizens and hackers into first-class participants of the digital transformation, giving them the power to develop and maintain software which impacts their daily life. To sustain this switch, the Team is building hackerspaces throughout the country, to increase awareness of open practices, and is turning all developers paid with public money into open source contributors. After this talk, you will know how to "hack your government", how to participate in this change (even if you are not Italian!) and how we are working to spread this idea throughout all of Europe. - **Speaker:** Riccardo Iaconelli - **Track:** [Community devroom](https://archive.fosdem.org/2018/schedule/track/community_devroom/) - **Room:** [K.4.601](https://archive.fosdem.org/2018/schedule/room/k4601/) - **When:** Saturday 3 February 2018, 10:50–11:15 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/community_italy_most_hacker_friendly_country/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “Italy: the most hacker-friendly country?” by Riccardo Iaconelli, FOSDEM 2018. **Original recording:** [2018/K.4.601/community_italy_most_hacker_friendly_country.webm](https://video.fosdem.org/2018/K.4.601/community_italy_most_hacker_friendly_country.webm) f...https://peertubewatch.b-cdn.net/streaming-playlists/hls/364b06b3-49ac-4154-8158-a1e043a47dd1/2d255492-4521-4d12-87ee-c63603817235-master.m3u8https://peertube.watch/videos/embed/7GRpajkkFc5JiADCtXdcgP2028002026-10-08T23:44:24.287ZFOSDEMFOSDEM 2018CommunityYESFOSDEM 2018NOhttps://peertube.watch/w/kQwJECrPpFcYNxhHERA1Jq2026-10-09T00:09:08.695Zhttps://peertube.watch/lazy-static/thumbnails/01f3c7a5-3acf-4570-8820-6d8127c4a977.jpgValgrind register allocator overhaulRegister allocator is a key component in Valgrind's VEX subsystem. Superficially it only translates virtual registers to the real ones. But is that really all? What actually happens under the covers, what algorithms are at play here and what are the constraints under which it operates? Last year, a major overhaul of the Valgrind VEX register allocator has been done, resulting in a new version v3 which is now used by Valgrind. In addition to a new design, new register allocation algorithms have been also implemented, producing faster and smaller code. A brief introduction to Valgrind VEX subsystem will be given, to put the register allocator component and its interfaces into context. Then the operation of register allocator v3 will be presented in an illustrative way, including major data structures. Code snippets from amd64 and aarch64 architectures will be used for examples. Brief comparison with v2 will be also given. After that, several algorithms will be described which contribute to the success of v3; again showing their operation on graphics. Finally there will be some time for discussion and feedback gathering. - **Speaker:** Ivo Raisr - **Track:** [Debugging tools](https://archive.fosdem.org/2018/schedule/track/debugging_tools/) - **Room:** [AW1.121](https://archive.fosdem.org/2018/schedule/room/aw1121/) - **When:** Saturday 3 February 2018, 11:00–11:25 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/debugging_tools_valgrind_regalloc/) **Slides & links** - [Live slides](http://slides.com/ivoraisr/valgrind-regalloc) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “Valgrind register allocator overhaul” by Ivo Raisr, FOSDEM 2018. **Original recording:** [2018/AW1.121/debugging_tools_valgrind_regalloc.webm](https://video.fosd...https://peertubewatch.b-cdn.net/streaming-playlists/hls/a0a446e9-69d9-4c01-a777-524af8de33fc/dd7a1205-525c-49b2-b486-f978521d51f7-master.m3u8https://peertube.watch/videos/embed/kQwJECrPpFcYNxhHERA1Jq1510002026-10-09T00:09:08.695ZFOSDEMFOSDEM 2018Debugging toolsYESFOSDEM 2018NOhttps://peertube.watch/w/njk3YuUMNHPBY7Y9FW1yyY2026-10-08T23:51:39.663Zhttps://peertube.watch/lazy-static/thumbnails/db6e01b6-14a5-421c-b7c6-4b4de261e947.jpgWelcomeWelcome to the Ada Developer Room at FOSDEM 2018, which is organized by Ada-Belgium in cooperation with Ada-Europe.

This session provides a brief intro to SDN in general, and more specifically to OpenDaylight, an open source platform for programmable SDN. Next we dive into network programmability, including why we need it and the role of NETCONF, YANG, and RESTCONF. Then we put the theory into practice as we install OpenDaylight as use it a platform for programming a sample network. - **Speaker:** Charles Eckel - **Track:** [SDN and NFV](https://archive.fosdem.org/2018/schedule/track/sdn_and_nfv/) - **Room:** H.1301 (Cornil) - **When:** Saturday 3 February 2018, 11:00–11:30 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/opendaylight/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “OpenDaylight as a Platform for Network Programmability” by Charles Eckel, FOSDEM 2018. **Original recording:** [2018/H.1301/opendaylight.webm](https://video.fosdem.org/2018/H.1301/opendaylight.webm) from the [FOSDEM video archive](https://video.fosdem.org/2018/).

They are open-minded, friendly, agreeable and so on. You feel like helping them. The problem is you are shy and you look at community people as gods. On top of that you don't want to mess up with their work or bother them with obvious and silly (to them) questions! This conference talk is based on my own true story. I will tell you about how I submitted my very first patch to the community. After some background presentation about how the community works, I will try to answer the following questions: - What can I do to help (and you'll see that even without coding you can do a lot!) ? - What's a contribution ? - What's a patch ? How can I create one? And I hope that sooner or later you'll come and join the community and you'll feel so proud of yourselves! - **Speaker:** Lætitia Avrot - **Track:** [PostgreSQL](https://archive.fosdem.org/2018/schedule/track/postgresql/) - **Room:** H.1302 (Depage) - **When:** Saturday 3 February 2018, 11:00–11:50 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/de_mystifying_contributing_to_postgresql/) **Slides & links** - [Talk on the FOSDEM PGDay website (may include slides)](https://www.postgresql.eu/events/fosdem2018/schedule/session/1705-de-mystifying-contributing-to-postgresql/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “De-mystifying contributing to PostgreSQL” by Lætitia Avrot, FOSDEM 2018. **Original recording:** [2018/H.1302/de_mystifying_contributing_to_postgresql.webm](https://video.fosdem.org/2018/H.1302/de_mystifying_contributing_to_postgresql.webm) from the [FOSDEM video archive](https://video.fosdem.org/2018/).

With an order of magnitude of hundreds of millions of euro in research, development and engineering effort it can actually be a major step toward reaching the post-Snowden internet we want. NLnet Foundation and Gartner Europe that wrote the strategic vision for the Next Generation Internet initiative will present the work they did in a unique collaboration which sought the expertise of key organisations and communities in the field - like RIPE (the European regional internet registry), GÉANT (research networks), the European assocation of country domain name organisations, ISP associations, the internet exchanges, the open source community (FSFE), the digital civil rights community (EDRi) and Internet Society. So not just the separate communities that operate different 'layers' (or rather slices) of the technology but also what we consider 'ethical guardians' of the internet. 2018 celebrates the fifth anniversary of the Edward Snowden revelations. Full details about covert mass scale surveillance at internet scale stripped the internet naked of every romantic assumption we held about it. The news sent a transformative shock throughout the global technology community. We were all convinced the internet would soon fix these horrible security shortcomings now that we knew - although naivity was destroyed and the internet would never be the same again. The world has fast forwarded itself five years. We must conclude - with some sadness - that the internet was not fixed for us. We are still waiting for major structural change. To the regular end user, a safe and secure 'post-Snowden' internet is far away: in day to day usage they still by and large have to use the same unfixed and insecure internet we had before.

It's time to look back: analyze the migration from Python 2 to Python 3, see the progress we made on the language, list bugs by cannot be fixed in Python 2 because of the backward compatibility, and discuss if it's time or not to bury Python 2. Python became the defacto language in the scientific world and the favorite programming language as the first language to learn programming. Draft of the talk: - Growing populary of the Python programming language - Defacto language in the scientific world, replacing other closed source and more specialized but limited language - Favorite programming language used as the first language to learn programming - Port Python 2 code to Python 3 - Port Python 2 code to Python 3 - No: "Add support for Python 3", don't loose Python 2 support - Port Python 3 code to Python 2 - Python changes to make the transition smoother: - PEP 414: u"syntax" reintroduced in Python 3.3 - PEP 461: bytes % args, Python 3.5 - More "Py3k" warnings added to Python 2.7.x - Linters like flake8 detect some issues - six, futures, modernize, 2to6, etc. - Analysis of the transition - Good: At Pycon US 2014, Guido van Rossum announced that the Python 2.7 support was extended from 2015 to 2020 to give more time to companies to port their applications to Python 3. - Bad: 2to3: "drop Python2 support at once", don't work when you have dependencies. - If done again, would it be different? Yes, obviously. - Python 4 will be different than Python 3: no more "break the world" release, but a "regular deprecation period" release, as *any* other release.

Conan is a portable package manager, mainly intended for C/C++, that makes library packaging possible (even pleasant!). After a brief presentation of Conan, I'll show how we're using it to deal with our new C++ project's dependencies. Last time I had to rebuild dependencies (for the new MSVC release) was horrible, it took me (only) a week! There were no build scripts for most of them, and I was a real newbie in dependency management. After hitting a lot of walls (e.g. MT vs MD, building Autotools-based projects on Windows, etc...), I swore never to go through that process again. I've decided to give Conan a try when a new project was announced. Within a couple of weeks, I've managed to build binaries for x86/x64, Debug/Release (including proper PDB packaging), shared/static, Windows/macOS/Linux. Integrating Conan to our CI system was trivial, upgrading a dependency is now a matter of minutes. First, I'll show how to create, upload, and install packages before diving into cross-compilation with Conan. - **Speaker:** Théo Delrieu - **Track:** [Package Management](https://archive.fosdem.org/2018/schedule/track/package_management/) - **Room:** [K.3.201](https://archive.fosdem.org/2018/schedule/room/k3201/) - **When:** Saturday 3 February 2018, 11:00–11:30 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/conan/) **Slides & links** - [Conan's documentation](https://conanio.readthedocs.io/en/latest/) - [Conan github page](https://github.com/conan-io/conan) - [Conan Website](https://conan.io) - [Tanker Website](http://tanker.io) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “Packaging C/C++ libraries with Conan” by Théo Delrieu, FOSDEM 2018. **...https://peertubewatch.b-cdn.net/streaming-playlists/hls/d08d990f-4568-4d1f-bdd7-3681bd0af644/0bdb3925-5b67-4d51-b298-58e14a138a92-master.m3u8https://peertube.watch/videos/embed/rKFbMYmbPu6hFxa4iqvTLY1773002026-10-09T02:58:25.901ZFOSDEMFOSDEM 2018Package ManagementYESFOSDEM 2018NOhttps://peertube.watch/w/dqVS15LE7gWsenbHetAD562026-10-09T03:44:36.764Zhttps://peertube.watch/lazy-static/thumbnails/5a934801-4375-4e63-b9ce-2ab014a9d6ac.jpgGnucap, and analog and mixed signal simulationThis talk will present an overview of analog(ue) and mixed-signal simulation, with a focus on Gnucap .. the GNU Circuit Analysis Package.

We will then give you a tour of our system, how it integrates with the developer's workflow, what we are working on, and we managed to grow from a couple of thousands tests executed per week to over 4 millions! We will also present the changes we have done to the IGT test suite to become less Intel-specific and serve the needs of multiple drivers. Upstream development requires never regressing the features that were already present in previous versions. We believe that this is not only the right thing to do, it is also increasing in relevance as more and more products move towards this model. To embrace this model, we try to catch unintentional regressions as early as possible through our CI system. This improves the productivity of our developers (fewer bugs coming months after the code was committed), and provide users with a smoother upgrade path (either through the product manufacturer or by upgrading the kernel themselves). The Intel GFX CI has grown massively in the past 1.5 years: the number of machine doubled; the test coverage went from 260 tests/machine up to over 4k; the number of tests executed went from 100k/week to over 4M; pre-merge testing time dropping to an average of 30 minutes despite the increased usage. We will then tour the audience through our different services, how they integrate with the developers' workflow, and how we manage to keep track of failures (and file them). Finally, we will share what are our current developments, our goals, and what we are doing to the IGT test suite in order make it useful for more drivers than Intel. - **Speakers:** Martin Peres, Arek Hiler - **Track:** [Graphics](https://archive.fosdem.org/2018/schedule/track/graphics/) - **Room:** [K.4.401](https://archive.fosdem....https://peertubewatch.b-cdn.net/streaming-playlists/hls/ba292a56-a200-40a0-9d67-3ee46fa39a59/38381646-7f3f-488d-9e65-43d0337d658f-master.m3u8https://peertube.watch/videos/embed/oZioUnv4xuesTuVKfWRSjV3036002026-10-09T04:04:00.095ZFOSDEMFOSDEM 2018GraphicsYESFOSDEM 2018NOhttps://peertube.watch/w/vMXX64xNsiMVEWFExRnMQh2026-10-09T04:28:32.151Zhttps://peertube.watch/lazy-static/thumbnails/696bc6e0-adc2-41cc-9e68-7db39ff56523.jpgThe free toolchain for the STM8**Getting into first place when non-free tools had years of head start.** The STM8 is STMicroelectronics' current 8-bit microcontroller architecture. In recent years a free toolchain or the STM8 architecture appeared and quickly surpassed the non-free ones. The central part of the toolchain is the Small Device C Compiler (SDCC), which features some optimizations suited to highly irregular architectures such as the STM8 The talk introduces all parts of the free toolchain for the STM8 and also discusses remaining gaps. The STM8 is a popular 8-bit architecture by ST Microelectronics commonly used in household electronics, automotive application and industrial controls. For quite a while there were no free tools, and the irregular architecture makes it hard to support in GCC or LLVM. In recent years free tools for it started to appear and now form a free toolchain that surpassed preexisting non-free ones. The most important part is the Small Device C Compiler (SDCC). New tree-decomposition-based algorithms from recent compiler research have been implemented in SDCC, including a new register allocator particularly suited to irregular architectures with few registers. SDCC quickly surpassed the non-free compiler in standard compliance and OS support and generates substantially faster integer code. Programs can be flashed by stcgal (via a serial link on STM8 devices that have a bootloader) and stm8flash (via the SWIM interface of ST-LINK hardware). OpenOCD and GDB allow on-target debugging via the ST-LINK. IDEs complete the development environment. However, stcgal still needs non-free binary blobs for use with some devices and the ST-LINK has non-free firmware. SDCC still falls short in floating-point performance. While there are some ports of free RTOSes that use the free toolchain for the STM8, more would be desirable. - **Speaker:** Philipp Klaus Krause - **Track:** Embedded, mobile and automotive - **Room:** [UD2.218A](https://archive.fosdem.org/2018/schedule/roo...https://peertubewatch.b-cdn.net/streaming-playlists/hls/f143f897-d7d3-4f4a-b41d-b54bd28482fc/b3455c10-778f-4f8a-9a7c-31d591521bc2-master.m3u8https://peertube.watch/videos/embed/vMXX64xNsiMVEWFExRnMQh1418002026-10-09T04:28:32.151ZFOSDEMFOSDEM 2018Embedded, mobile andYESFOSDEM 2018NOhttps://peertube.watch/w/44ULaWKd6VqKagyA6m8CU12026-10-09T04:58:07.658Zhttps://peertube.watch/lazy-static/thumbnails/0b9fb8ea-f320-4e83-8d35-7fd06c7160ce.jpgAn Introduction to Ada for Beginning and Experienced ProgrammersAn overview of the main features of the Ada language, with special emphasis on those features that make it especially attractive for free software development. Ada is a feature-rich language, but what really makes Ada stand-out is that the features are nicely integrated towards serving the goals of software engineering.

In this talk we will present a user space GPU multiplexer solution for Intel Gen8+ that takes advantage of those hardware features. It supports the concurrent execution of multiple 3D applications, while still retaining a low code complexity. Furthermore, we will give an holistic overview of the inner workings of a modern graphics stack. - **Speaker:** Sebastian Sumpf - **Track:** [Microkernels](https://archive.fosdem.org/2018/schedule/track/microkernels/) - **Room:** [AW1.126](https://archive.fosdem.org/2018/schedule/room/aw1126/) - **When:** Saturday 3 February 2018, 11:05–11:35 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/microkernel_genode_gpu_multiplexing/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “GPU resource multiplexing in component based systems” by Sebastian Sumpf, FOSDEM 2018. **Original recording:** [2018/AW1.126/microkernel_genode_gpu_multiplexing.webm](https://video.fosdem.org/2018/AW1.126/microkernel_genode_gpu_multiplexing.webm) from the [FOSDEM video archive](https://video.fosdem.org/2018/).

When limitations of older hardware join, the true fun begins. This talk explores some of the issues found while evaluating Mercurial as new VCS for NetBSD and how they got resolved. The NetBSD project has been developing an Operating System for almost 25 years now. It is one of the oldest users of CVS still around and there is a strong desire to change that. Such a migration is challenging and requires acceptance from the active developers and infrastructure changes. One central aspect for the buy-in from the community is the scalability of the new system and its limitations. The talk starts with an overview of the existing work on migrating the NetBSD repository to modern VCS. The performance of important operations will be compared and bottlenecks identified. Based on the results, reasonable target requirements are identified. An in-depth analysis of critical parts of Mercurial will be presented and how those bottlenecks were addressed. - **Speaker:** Jörg Sonnenberger - **Track:** [BSD](https://archive.fosdem.org/2018/schedule/track/bsd/) - **Room:** [K.3.401](https://archive.fosdem.org/2018/schedule/room/k3401/) - **When:** Saturday 3 February 2018, 11:05–11:50 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/netbsd_and_mercurial/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “NetBSD and Mercurial” by Jörg Sonnenberger, FOSDEM 2018. **Original recording:** [2018/K.3.401/netbsd_and_mercurial.webm](https://video.fosdem.org/2018/K.3.401/netbsd_and_mercurial.webm) from the [FOSDEM video archive](https://video.fosdem.org/2018/).

Query languages like openCypher, implemented in systems like Neo4j, SAP HANA Graph and Redis Graph, allow the intuitive definition of graph patterns including structural and semantic predicates. For now, graph query languages are most prominent in graph database systems such as Neo4j. However, we think that many systems can benefit from having such a language in their toolbox. One of these systems is Apache Spark, which is one of the most popular open source frameworks in the context of distributed processing of large data volumes within complex analytical workloads. To bring the benefits of Cypher from the graph database realm into the world of Big Data, we at Neo4j started developing Cypher for Apache Spark (CAPS). CAPS is primarily focused on graph-powered data integration and graph analytical query workloads within the Spark ecosystem. In addition, CAPS is our testbed for Cypher language extensions as specified in the openCypher project; for example, multiple graphs, graph transformations and construction, and query composition. In our talk, we want to motivate use-cases for CAPS and give an overview of new querying capabilities which we demonstrate using Apache Spark and Apache Zeppelin. Furthermore, we briefly present the internal architecture highlighting the main differences between Neo4j and CAPS. **Intended audience and goal of the talk** Developers and analysts, trying to express graph queries on distributed graphs **Links to background information on the given talk for the hungry and impatient** - [OpenCypher](http://www.opencypher.org/) - [Neo4j](https://neo4j.com/) - [Apache Spark](https://spark.apache.org/) **Links to previous talks, code snippets or repositories** - [CAPS](https://github.com/opencypher/cypher-for-apache-spark) - **Speakers:** Martin Junghanns, Max Kießling - **Track:** [Graph Processing](https://archive.fosdem.or...https://peertubewatch.b-cdn.net/streaming-playlists/hls/dfe829dc-5ecc-4c3e-aa66-8b82c8767f41/30e49f3e-9a9b-4f14-820a-063304c77d90-master.m3u8https://peertube.watch/videos/embed/tDDaeL1DLfApcx1s6Wt6bi1957002026-10-09T06:41:09.527ZFOSDEMFOSDEM 2018Graph ProcessingYESFOSDEM 2018NOhttps://peertube.watch/w/8efNcmkzp1gMgmeD1J78t52026-10-09T07:48:38.512Zhttps://peertube.watch/lazy-static/thumbnails/90b36a98-fefd-4e10-98f4-956a085fa107.jpgA slightly different nesting: KVM on Hyper-VThis may come as a surprise but it is already possible to run nested KVM inside Hyper-V VMs (and this includes several instance types on Azure). Such workloads, however, may not always perform very well. Some limitations come from x86 architecture and conceptual differences between KVM and Hyper-V, other issues could be dealt with within KVM. In this talk Vitaly will go through different performance bottlenecks of nested KVM-on-Hyper-V deployments. The presentation will mainly be focused on low-level features: hardware support for nested virtualization, clocksources and clockevents, virtual device drivers. Benchmark data and general thoughts on the usefulness of such deployments won't be missing too. In the talk Vitaly will try to highlight challenges in heterogeneous nested virtualization, namely the current status, issues and future work for running KVM on top of Hyper-V. The talk is intended for everyone interested in virtualization technologies. Less experienced people may learn about the very basics of virtualization in nested environments (and, actually, virtualization in general), experienced developers may find something interesting in learning about 'non-traditional' nesting, review the suggested approaches or even suggest a solution. - **Speaker:** Vitaly Kuznetsov - **Track:** [Virtualization and IaaS](https://archive.fosdem.org/2018/schedule/track/virtualization_and_iaas/) - **Room:** UB2.252A (Lameere) - **When:** Saturday 3 February 2018, 11:15–12:00 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/vai_kvm_on_hyperv/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “A slightly different nesting: KVM on Hyper-V” by Vitaly Kuznetsov, FOSDEM 2018. **Original recording:** [2018/UB2.252A/vai_kvm_on_hyperv.webm](https://video.fo...https://peertubewatch.b-cdn.net/streaming-playlists/hls/3a89c21e-d99f-42ac-81a3-221c5ea6d96e/a5308ad2-2672-4071-b3c8-f31743298985-master.m3u8https://peertube.watch/videos/embed/8efNcmkzp1gMgmeD1J78t52611002026-10-09T07:48:38.512ZFOSDEMFOSDEM 2018Virtualization and IaaSYESFOSDEM 2018NOhttps://peertube.watch/w/mchUXbDzP9jDKq725QxgFU2026-10-09T07:52:17.964Zhttps://peertube.watch/lazy-static/thumbnails/f6a1868f-05c2-49ca-8d73-28d22d18ae94.jpgÆ-DIR -- Authorized Entities Directory**from paranoid user management to secure system management** This talk will introduce Æ-DIR, a paranoid identity and access management (IAM) system based on pure OpenLDAP. The talk will detail the data model used for delegated administration and its use e.g. for a strictly authorizing SSH proxy. Furthermore it introduces OATH-LDAP, a OATH-based OTP authentication system with pure LDAP backend and the enrollment process used for secure initializing yubikey tokens. The conclusion of the talk will highlight want else will be done with the data and role model in the near future. Æ-DIR and OATH-LDAP are free software projects. This talk will present a concept and real-world implementation of a privileged identity and access management system (IAM, PAM) purely based on OpenLDAP. The main goal of Æ-DIR (besides challenging Unicode handling in various software with its name) is to follow the delegation, need-to-know and least-privilege principles as strict as possible. The visibility of user, group, sudoers, etc. is limited by OpenLDAP’s set-based ACLs. All systems and services, no exception(!), have to individually authenticate to be authorized to access Æ-DIR. The talk will give some additional information about the secured base configuration of OpenLDAP, tools developed and some experiences made when migrating/attaching 7000+ servers to this user management. Furthermore the architecture of a SSH gateway is shown which uses the very same access control data to authorize SSH connections passing through the gateway. Finally the talk will outline some additional to-dos, and rough ideas how to further develop this system. OATH-LDAP defines a schema, a functional model and a LDAP-based enrollment for OATH-based authentication tokens. It is designed to be used with any LDAP server, but especially is ready-to-use integrated with Æ-DIR. It is actually used combined with a highly secure enrollment process (no QR code displayed!) for two-factor HOTP authentication with...https://peertubewatch.b-cdn.net/streaming-playlists/hls/a38a60ad-9ddc-40ed-869a-76bca16b41be/c677e92c-0a63-40ff-a52f-0374b8b7191c-master.m3u8https://peertube.watch/videos/embed/mchUXbDzP9jDKq725QxgFU1828012026-10-09T07:52:17.964ZFOSDEMFOSDEM 2018Identity and Access ManagementYESFOSDEM 2018NOhttps://peertube.watch/w/ivdaMaxhgetgLGYA2HBcAM2026-10-09T08:19:48.654Zhttps://peertube.watch/lazy-static/thumbnails/3ebbd468-a662-4bc7-b9b9-a9a61d282ead.jpgMedia 101 for CommunitiesIn a world of constant news cycles, getting the word out about your project seems nearly impossible.

It solves certain issues, but often raises many others. Paweł will present a fresh open hardware approach at providing remote access (including device flashing, debugging and power management) to embedded devices - [MuxPi](https://wiki.tizen.org/MuxPi), successor of [SD MUX](https://wiki.tizen.org/SD_MUX) board (showcased during FOSDEM 2016 and Embedded Linux Conference 2016). Presentation will introduce novices to the topic of testing on remote embedded devices and previous attempts to do so. It will focus on software components of the new Tizen GNU/Linux distribution's testing laboratory (currently in the process of being published open source): - Boruta - board farm management system, - Weles - LAVA-compatible testing framework, - Perun - binary image testing system. Advanced capabilites of presented hardware (MuxPi) are discussed during talk in [Embedded, mobile and automotive devroom](https://fosdem.org/2018/schedule/event/testing_remote_devices/). This talk will hopefully encourage discussion on this topic or inspire attendees to try those components out in their own setups and share feedback on what can be further improved. - **Speaker:** Paweł Wieczorek - **Track:** [Testing and automation](https://archive.fosdem.org/2018/schedule/track/testing_and_automation/) - **Room:** [H.2213](https://archive.fosdem.org/2018/schedule/room/h2213/) - **When:** Saturday 3 February 2018, 11:25–12:10 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/remote_embedded_testing/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “Piece of cake” by Paweł Wieczorek, FOSDEM 2018. **Original recording...https://peertubewatch.b-cdn.net/streaming-playlists/hls/ef3dea51-6c1d-4476-b9fd-5d5bb0974814/73fb9dc7-7d24-49c1-9bf8-89adf8ae9dab-master.m3u8https://peertube.watch/videos/embed/vxtjCykXeKKZPRxfrfLs1d2189002026-10-09T09:04:34.978ZFOSDEMFOSDEM 2018Testing and automationYESFOSDEM 2018NOhttps://peertube.watch/w/n5Js7oLUwJBz59afdNCGLZ2026-10-09T09:10:47.195Zhttps://peertube.watch/lazy-static/thumbnails/fcdfd4b3-37cf-476d-9f2f-8889a62066c5.jpgValgrind's Memcheck tool vs Optimising Compilers**Keeping the false positive rate under control** The ongoing work to improve the accuracy of definedness tracking in the face of newer more aggressively optimizing compilers. Valgrind's Memcheck tool reports various kinds of errors. One of the most important ones are those where an if-conditions or a memory address uses undefined data. To do this, it tracks the definedness of every bit in the process, and "follows" any undefinedness through arithmetic operations (Add, Sub, Mul, Or, Xor, etc). This tracking is expensive and so Memcheck makes compromises, trading off exactness for speed. That has worked well for many years. However, as compilers become more aggressive, this works less and less well. In particular, Memcheck now often reports false errors in optimised code from GCC 6, Clang 4, and later versions. This is a problem because one of Memcheck's main strengths is the accuracy of its analyses. In this talk I'll present my ongoing work to improve accuracy of definedness tracking. I'll mostly talk about various examples involving integer addition and comparisons, and will avoid gory details of Memcheck's internals. I'll also show two problems to which I have no solution. The talk should be accessible to anyone with some familiarity of basic integer arithmetic (add, sub, and/or/xor, etc) and is curious about how undefinedness "flows" through these operations.

We will give the motivation and background for developing Ligato, describe its the architecture, and provide examples or real-world use cases. We will compare the performance and scale of Ligato-based VNF deployments with performance and scale of VNFs deployed in other environments, such as OpenStack. A virtual network function (or VNF), as commonly known today, is a software implementation of a network function that runs on one or more virtual machines (VMs) on top of the hardware networking infrastructure — routers, switches, etc. Individual virtual network functions can be connected or combined together as building blocks to offer a full-scale networking communication service. A VNF may be implemented as standalone entity using existing networking and orchestration paradigms - for example being managed through CLI, SNMP or Netconf. Alternatively, an NFV may be a part of an SDN architecture, where the control plane resides in an SDN controller and the data plane is implemented in the VNF. A cloud-native VNF is a VNF designed for the emerging cloud environment - it runs in a container rather than a VM, its lifecycle is orchestrated by a container orchestration system, such as Kubernetes, and it's using cloud-native orchestration paradigms. In other words, its control/management plane looks just like any other container based 12-factor app. to orchestrator or external clients it exposes REST or gRPC APIs, data stored in centralized KV data stores, communicate over message bus, cloud-friendly logging and config, cloud friendly build & deployment process, etc., Depending on the desired functionality, scale and performance, a cloud- native VNF may provide a high-performance data plane, such as the VPP.

But underneath, they are very different in their goals, features and approach to create packages and manage dependencies. Some package management environments are bazaars and some are cathedrals. What does this mean? Join me for a tour of horizon to compare and contrast the goals and ways of key package package management environments: What's their purpose? How we use then and how they are meant to be used? How do they deal with dependencies differently and why? Who creates and uses the packages?

Today most of BSPs are provided as Yocto "recipes" and/or metadata. They are several extensions providing RT capabilities to the Linux kernel. Number one is PREEMPT*RT, maintained by Thomas Gleixner and supported by the Linux foundation since 2015. Second one is Xenomai mainly based on a co-kernel architecture (such as RTLinux). It was created by Philippe Gerum, a french RT expert and is maintained by a small group of contributors. Current version is 3.0.5 and can be used in dual kernel mode (Cobalt) or on top of PREEMPT*RT in a single kernel approach (Mercury). Using RT extension with Yocto is not that easy because linux-yocto-rt kernel is not usable on main embedded target such as ARM (as it works on QEMU target only). Using Xenomai is much more complicated as it needs several steps (patching the kernel, installing user-space libraries, building an extended SDK). During the conference we will decribe how to build a Yocto Linux image using PREEMPT\_RT for famous boards such as Pi 3 or BeagleBone Black. Some Xenomai support is provided by meta-eldk from DENX but it supports only Xenomai 2.6. We will describe meta-xenomai as we maintain it for our customers (available on GitHub). That new meta-xenomai layer is based on Xenomai 3.x and very recent kernel. Then we will explain how to build a simple Xenomai application based on a periodic task. Finally we will compare performances of both extension (PREEMPT\_RT and Xenomai) on same hardware. - **Speaker:** Pierre Ficheux - **Track:** Embedded, mobile and automotive - **Room:** [UD2.218A](https://archive.fosdem.org/2018/schedule/room/ud2218a/) - **When:** Saturday 3 February 2018, 11:30–12:00 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/...https://peertubewatch.b-cdn.net/streaming-playlists/hls/dd8ca302-8dab-4254-a795-ff35a4037885/19fa72ac-5af5-4471-bd4c-7368ebfbe7d4-master.m3u8https://peertube.watch/videos/embed/tmKQJJsmTJbDE8fS6pMX8t1521502026-10-09T12:13:24.212ZFOSDEMFOSDEM 2018Embedded, mobile andYESFOSDEM 2018NOhttps://peertube.watch/w/no3hmCN96LcaT51Ea7wmFb2026-10-09T12:17:23.398Zhttps://peertube.watch/lazy-static/thumbnails/5ab26396-4180-470a-ab73-92540899b755.jpgDocumentation convergence project for LibreOffice**Make just one documentation for all** LibreOffice like other office suites, is a sophisticated, ubiquitous and complex end-user application, that demands good documentation to continue its strive. The current situation for LibreOffice documentation is that producing contents is still a lenghty and hard task, often requiring rework depending on different sort of publiccation needed. In this presentation, we will summarize the efforts done so far within the LibreOffice ecosystem and make the point on the need for a different approach to make the LibreOffice documentation an element of communty gathering and contribution, extending the range of the quality of the software. Complex softwares for end-users like office suites or desktop environment, to name a few, are impacted in their adoption because of the need to educate and train users to the new tools. Undocumented software raise a set of issues that prevents broad adoption by the organizations or governments, and leave brilliant ideas and features into obscrurity. The Document Foundation and it's flagship software LibreOffice, as well as other FOSS communities needs to address the issue of making the end-user documetnation broadly available and updated. On the other hand, end users being part of the software community, are often eager to collaborate and contribute to the software documentation, but hit a quite steep entry barrier because of the development skills need in editing software help files or on advanced word processing skills for editing a guide with the software. Also, Q&A-shaped web services, wikis and dynamic multimedia documentation also bring challenges to documentation because of the need for accuracy and update. The purpose of the presentation is to deliver a vision on the optimal documentation production for complex end-user softwares, that will address several documentation issues existing in the FOSS business and community envoronment.

Many of them contribute to free and open source software, and some of them publish their own free and open source software. All of this is good, and should be encouraged to continue. In addition to that, though, many large companies have philanthropic arms; charitable foundations either operated by the company or closely aligned with the company, and primarily funded by the company. These foundations generally have focus areas, which include almost every conceivable charitable cause except... free and open source software! This presentation will talk about Bloomberg's journey to add software philanthropy to its global charitable contributions, including the mundane aspects of running volunteer coding events, soliciting mentors/leaders to participate, organizing employee (and non-employee) participation, and others, but also how this type of philanthropy can be included in 'employee giving' and similar programs.

When Khronos published the first release of Vulkan, almost 2 years ago, shaders used a binary format, called SPIR-V, originally developed for use with OpenCL. That means that the two major public 3D graphics API were using different shading languages, making porting from one to the other more complicated. Since then there were efforts to allow making this easier. On July 2016, the extension ARB*gl*spirv was approved by Khronos, that allows a SPIR-V module to be specified as containing a programmable shader stage, rather than using GLSL, whatever the source language was used to create the SPIR-V module. This extension is now part of OpenGL 4.6 core, making it mandatory for any driver that wants to support this version. This talk introduces the extension, what advantages provides, and explain how it was implemented for the Mesa driver. - **Speaker:** Alejandro Piñeiro - **Track:** [Graphics](https://archive.fosdem.org/2018/schedule/track/graphics/) - **Room:** [K.4.401](https://archive.fosdem.org/2018/schedule/room/k4401/) - **When:** Saturday 3 February 2018, 11:55–12:45 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/spirv/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “ARB\_gl\_spirv: bringing SPIR-V to Mesa OpenGL” by Alejandro Piñeiro, FOSDEM 2018. **Original recording:** [2018/K.4.401/spirv.webm](https://video.fosdem.org/2018/K.4.401/spirv.webm) from the [FOSDEM video archive](https://video.fosdem.org/2018/).

VPP is a fast network data plane, part of the Linux Foundation FD.io project. It is designed on top of DPDK to run network workloads at ludicrous speeds using vector packet processing technology. Networking-VPP is a VPP network driver for Neutron designed to take advantage of VPP’s performance. VPP brings the performance; Networking-VPP brings the resiliency, simplicity, security and scalability required to make it useful in OpenStack environments. We’ll talk about what VPP is and why it’s a good choice for network workloads, particularly demanding ones such as NFV applications; how the ML2 driver is put together and why you can trust it to hold up in cloud environments (and even debug it); and the performance we see when we put the two together in a real world OpenStack deployment. - **Speaker:** Jerome Tollet - **Track:** [SDN and NFV](https://archive.fosdem.org/2018/schedule/track/sdn_and_nfv/) - **Room:** H.1301 (Cornil) - **When:** Saturday 3 February 2018, 12:00–12:30 (Brussels time) - **Schedule:** [FOSDEM 2018 event page](https://archive.fosdem.org/2018/schedule/event/networking_vpp/) --- **Licence:** [Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE)](https://creativecommons.org/licenses/by/2.0/be/deed.en) (as stated in [the FOSDEM video archive](https://video.fosdem.org/)). **Attribution:** “Networking-VPP” by Jerome Tollet, FOSDEM 2018. **Original recording:** [2018/H.1301/networking_vpp.webm](https://video.fosdem.org/2018/H.1301/networking_vpp.webm) from the [FOSDEM video archive](https://video.fosdem.org/2018/).

In this talk, I will share my experience of building a testing framework for distributed systems, revisiting common mistakes, how to avoid them, and showing how to take advantage of the power of Go to make sure our systems behavior match our original expectations, with scalability in mind through automation. Containers are everywhere. Whether teams decide to use bare containers, orchestrators or enterprise solutions built on top of these technologies, the result is the same in terms of testing. With rolling updates and fault-tolerant clusters getting more popular every day in organizations of all sizes, availability issues are now easier to handle, whereas the complexity of reliability in our systems stays the same or even increases. Given the nature of distributed systems, a traditional approach towards testing is not enough. Smoke, integration and unit tests should be only the entry point, while e2e tests are no longer a luxury item in our developer toolset. However, writing and running them with scale and time constraints in mind is a task that is easier said than done. Since Go was born with tools for developers in mind, it's a great language thatenables productivity, which sometimes is cited as an excuse to avoid writing stronger e2e cases. In this talk, I will share my experience of building a testing framework for distributed systems, revisiting common mistakes, how to avoid them, and I will show how to take advantage of the power of Go to write reliable e2e tests to make sure our systems' behaviors really match our original expectations, with scalability in mind through automation. - **Speaker:** Verónica López - **Track:** [Go](https://archive.fosdem.org/2018/schedule/track/go/) - **Room:** H.1308 (Rolin)...https://peertubewatch.b-cdn.net/streaming-playlists/hls/93ade941-e8ce-45df-98e2-594f29d18b44/30add56a-26f7-41b8-bd82-23a08f3d50f0-master.m3u8https://peertube.watch/videos/embed/jeG9YJvGF7rndc4aV2S7cN1610002026-10-09T20:36:31.722ZFOSDEMFOSDEM 2018GoYESFOSDEM 2018NOhttps://peertube.watch/w/6So8rTQarfaM6zLKeZQGvS2026-10-09T22:16:03.989Zhttps://peertube.watch/lazy-static/thumbnails/6252fb48-323c-4a4e-825a-1b5a747217d1.jpgAn update on VLC and the VideoLAN community**VLC 4.0, VLC.js, VLC-VR?** This talk will present some updates on the VideoLAN community and on VLC.
