You've heard that DevOps (or ITOps, or WhateverOps) will solve all your development-to-deployment problems and how agile processes can increase the velocity of your projects. But you also likely know that it's not a silver bullet that solves all problems. This session will discuss how DevOps helps, what the pitfalls are, and how to avoid failure while squeezing the BEST out of DevOps. about this event: https://c3voc.de Sun, 28 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1440-eng-DevOps_delivering_value_in_a_judgmental_world_sd.mp4?1495985913 LxGiZFjmRQy3U6o41kSPSA 2017-05-28T00:00:00+02:00 craig gardner No osc17, 1440 Golden Hammers never had it so good DevOps is one of the Industry's great buzz words.

Just one problem, this is a road long travelled before, such as in the application dark ages of Win32 applications and DLLs. And it worked out so wonderfully there... Do we risk a future where, like the resurrected dinosaurs of Jurassic Park, this family of applications will break their containment and start eating our users? This session will try to present a fair argument about the situation, frankly discussing the benefits promised by these technologies, but highlighting the very real issues and risks their widespread adoption could, and in some cases are, already bringing to the table. The talk with cover the promised benefits of application containers, such as AppImage, Snappy and Flatpak. It will detail the empowerment of developers who use the technologies, the ability for upstream projects to have a much closer role in delivering their software, and the benefits that brings to both the upstream projects and their users. But as a counter to those benefits, the session will detail some of the risks and responsibilities that come with that technology. The complexities of library integration, the risk of introducing new forms of dependency issues, and the transference of responsibility for those issues, plus security, away from the current Distributions delivering upstream projects towards those upstream projects directly. As a conclusion, the session will start to ask the question, what the hell should openSUSE do about this mess? How much can we help fix it or mitigate the problems? How much do we want to be involved in that new world? about this event: https://c3voc.de Sun, 28 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1320-eng-openSUSE_Jurrassic_Park_sd.mp4?1495983296 21fzINn6BBrFviNsVEN1Og 2017-05-28T00:00:00+02:00 Richard Brown No osc17, 1320 What should we do about Containerised Applications?

Its companion tool colplot, provides an easy to use web-based plotting package capable of displaying detailed statistics for multiple systems at the same time. Think of colmux, a third tool, as top-anything across a number of machines. It is capable of displaying anything collectl can collect in top-format, sorted by any column of your choice. For example, say you have a 100 node cluster, with colmux you can look at the disk wait times across thousands of disks sorted sorted from slowest to fasted, allowing you to easily identify bad or hot drives, OR look at memory consumption for leaks. How about a bad NIC consuming a CPU by interrupts? Or how about which process is doing the more disk reads, or write, or page faults? And remember, this is across a cluster. The focus of collectl has always been highly efficient metrics collection and display via a CLI, no pretty pictures and no databases to slow it down. However what it does have is an API to allow it to pass those metrics onto whatever high level tools one may wish to communicate with. For example it has native support for ganglia or graphite over a socket. If you have some other favorite tool it can usually be adapted to communicate with it as well. Unfortunately most centralized tools are easily overwhelmed with fine-grained metrics and can only deal with them at granularities in the 1-min range. Not to worry, collectl has the ability to record and save metrics to local disk at one rate and send simultaneously send them to a central tool at a different rate, making it possible to get a coarser-grained centralized view and if there is a problem, still have access to finer-grained data. Collectl has been used for monitoring some of the largest computing clusters in the world and in the last several years has been enhanced for monitoring Open Stack Clouds. It is currently packaged as part of OpenSUSE. about this event: https://c3voc.de Sun, 28 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1312-eng-collectl_-_a_system_monitoring_tool_like_no_other_sd.mp4?1495982839 L0a92AY4MXdIRWubHJn0Jg 2017-05-28T00:00:00+02:00 markseger No osc17, 1312 Collectl is a comprehensive, fine-grained monitoring tool that collects a vast quantity of system metrics Collectl was developed over a dozen years ago as a very lightweight yet highly detailed system monitoring tool, capable of collecting hundreds system performance metrics as frequently as every second.

Only OSS is used and will be presented during the talk. The process is automated with GitLab, GitLab-CI, Docker, Vagrant and several smaller projects we have or will publish on GitHub: * pyaptly (https://github.com/adfinis-sygroup/pyaptly) * pkgbuild-bot (https://github.com/adfinis-sygroup/gitlab-pkgbot) * docbuild-bot (https://github.com/adfinis-sygroup/gitlab-docsbot) We are sure that this fully automated approach for different uses cases brings a new angle into the CI/CT space. Properly packaging software (incl. signing) is still not that easy and many tend to work around it. Attendees will get new ideas how to fully automate the process of transforming source code to a ready-to-use package and not only parts of it. about this event: https://c3voc.de Sun, 28 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1308-eng-From_source_to_package_sd.mp4?1495980013 SUeG0aQcZ5L0C_WLvXetgA 2017-05-28T00:00:00+02:00 Michael Hofer No osc17, 1308 Leveraging the power of GitLab CI During this talk we'll show a complete CI/CT pipeline and how we automated the following tasks: * Render and publish RST / sphinx based documentation * Build and publish packages (deb + rpm) on a public repository (incl. signing) * Advanced testing of JS-based applications with Firefox and PhantomJS The idea is to automate the whole pipeline starting simple with application testing and finally deploying it or building and publishing the appropriate packages and documentations.

It powers command line tools like ‘abidiff’, which let users compare ABI changes between two different versions of a given ELF binary by analyzing just the binary and its ancillary debug information. The result of the binary comparison is a kind of hierarchical ‘diff’ which shows changes up to the types of the interfaces that constitute the ABI of an ELF program. This infrastructure allows software distributors (among other actors) to build specific tooling to review and analyze ABI changes that might occur whenever a shared library package is updated. That tooling might even be tailored to automatically prevent packages with unwanted incompatible ABI changes to reach users. This talk intends to present Libabigail, its architecture, its capabilities, its current limits, its associated tools and how it might be used to further build highly tailored ABI verification tooling. The talk will also explore the potential improvement paths that are currently identified, and from the feedback of the audience, explore improvement paths that are not yet identified. about this event: https://c3voc.de Sun, 28 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1234-eng-Libabigail_How_semantic_analysis_of_C_and_C_ELF_binaries_can_be_used_to_analyze_ABI_changes_sd.mp4?1495978370 5J96cLw9prhLQ4hlZv1ZUA 2017-05-28T00:00:00+02:00 dodjiseketeli No osc17, 1234 Libabigail is an infrastructure for semantic analysis of ELF binaries containing C or C++ programs.

Is your source code hosted at GitHub? Do you use continuous integration or continuous deployment? Why NOT? This short talk will be about some tricks we use in the YaST team for continuous integration. Because we need a specific environment we use the Docker containers for building and testing at Travis. This approach also decreased out maintenance effort and made the builds more reliable. Hopefully this talk encourages you to use continuous integration also for your projects.

This short talk will be about some tricks we use in the YaST team for continuous integration. Because we need a specific environment we use the Docker containers for building and testing at Travis. This approach also decreased out maintenance effort and made the builds more reliable. Hopefully this talk encourages you to use continuous integration also for your projects.

It is important to keep data safe and secure to protect the privacy of the users. Open source software like Nextcloud and openSUSE are key to provide the necessary tools to the users to protect their data and run their own infrastructure. But to provide the expected security to the users it is necessary that the software is configured correctly and always has the latest security patches. It was lately discovered by Nextcloud that a big number of cloud services running on the internet are not secured properly. Some of them, even operated by big organisations, are even trivial to hack. This is a challenge for the open source community that we need to address. This talk will cover the current problems with insecure services that were discovered by Nextcloud and discussed possible steps to improve the situation. Examples are easier to understand administration interfaces, better notifications to the admins if actions are needed and potentially live patching of software. The talk will discuss potential consequences and new challanges for Linux distributions around software distribution and better guiding of admins to make the right decissions around security. It will also discuss the current and upcoming federation features of Nextcloud and how to become part of the community. about this event: https://c3voc.de Sat, 27 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1328-eng-Preventing_cloud_data_breaches_in_open_source_sd.mp4?1495899511 X4dpEErwyiyiyFLzJWUOQg 2017-05-27T00:00:00+02:00 FrankKarlitschek No osc17, 1328 The privacy and the personal data on the internet are under attack by hackers and international espionage programs.

A key component is the NFV infrastructure which provides the environment on which the Virtual Networking Functions run. The ecosystem of software/hardware for the NFVI is growing day-by-day making end-users life very difficult: Which platform to buy? Which stack to deploy? Which Virtual Networking solution should be adopted? Answering all these questions is far from being an easy task. In this presentation, we will provide you with the current state of the art of the vSwitch ecosystem (i.e. Open vSwitch, VPP), discuss different approaches around common use cases, deployment and integration challenges (i.e. SDN controller and orchestration integration) and what questions you shall ask yourself before picking your final networking software stack. This presentation will help developers and end-users who are getting closer to the NFV world to familiarize themselves with the existing NFV technologies and, potentially, help them chose what to focus on based on our perspective. Attendees can expect a detailed update on the current open-source vSwitch portfolio, new trends and on-going discussions within the open-source community. about this event: https://c3voc.de Sat, 27 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1244-eng-Virtual_Networking_in_the_NFVi_sd.mp4?1495889621 VfmyqiuDevNeA1REbbHUXA 2017-05-27T00:00:00+02:00 Marco Varlese No osc17, 1244 Landscapes and Challenges NFV is a complex world made of hardware technologies and software stacks.

Which Virtual Networking solution should be adopted? Answering all these questions is far from being an easy task. In this presentation, we will provide you with the current state of the art of the vSwitch ecosystem (i.e. Open vSwitch, VPP), discuss different approaches around common use cases, deployment and integration challenges (i.e. SDN controller and orchestration integration) and what questions you shall ask yourself before picking your final networking software stack. This presentation will help developers and end-users who are getting closer to the NFV world to familiarize themselves with the existing NFV technologies and, potentially, help them chose what to focus on based on our perspective. Attendees can expect a detailed update on the current open-source vSwitch portfolio, new trends and on-going discussions within the open-source community. about this event: https://c3voc.de 00:46:33 https://media.ccc.de/v/1462-open-source-projects-and-product-management-need-pain-or-useless Patrick and Holger from ownCloud will question and discuss if Open Source Projects need Product Management and if it makes any difference.

The policies for this repo are aligned with SUSE in order to maintain supportability of the main OS, making the packages "safe" to install and use. Packages maintained for SUSE Linux Enterprise exist in many different individual projects - in particular the "devel" projects. Many of these packages would be useful for SUSE Linux Enterprise customers but some of them could interfere with functionality and supportability of the SUSE product if installed. The risk of breaking supportability makes it difficult for SUSE to recommend these community maintained packages to end customers. At the same time, SUSE encourages community efforts and wants to promote the community based packages to all users.

As it happens, openSUSE offers outstanding support for the Haskell language ecosystem and is therefore an ideal platform for discerning Haskell hackers who develop commercial-grade solutions. Both Tumbleweed and Leap support a whopping 2,200 Haskell packages that cover the entire LTS Haskell standard version 8.x. Furthermore, there exists a sophisticated infrastructure to easily maintain and update a package set of that size, which guarantees that important new releases make it into the distribution with a minimal delay. In this presentation, we would like to describe the current state of Haskell packaging in openSUSE, covering the following topics in particular: 1. Introduce Haskell briefly and explain why it kicks ass. 2. How can I install and set up a Haskell development environment with openSUSE Leap or Tumbleweed? 3. How can I package and deploy my own Haskell applications on openSUSE with the Open Build Sevice? 4. How does the underlying infrastructure work ("cabal2obs") that makes all this possible?

But what about if there is a new major release of your favorite Desktop? Or a major version update of your used Linux distribution? Today’s concepts are most of the time to apply the patches in the running system and risk that a running service or Desktop breaks, or apply them all by booting an installation media and wait for quite some time until you can access your machine again. Or your boot process is stopped for a long time during which the updates are applied. Or some patches fails to apply and your system is in an inconsistent state. A solution for this are transactional updates. Transactional updates are atomic, means either they applied successful, or if an error occurred, you have the same state as before. And if an update does not work, there is an easy way to go back to the last working state. There are different solutions for this, some require new package formats, other require a second partition and you can switch during the next reboot to the other partition. I want to present a third solution: using a standard package manager and leverage btrfs for this. With snapshots and rollback on btrfs, there is already everything available what you need.

They are already the better solution for power users & developers. Tumbleweed is the future of Rolling Releases. The methodologies, techniques, and capabilities of Tumbleweed are opening up new doors, creating possibilities, and disrupting existing technologies beyond its borders. This session will explain how and why openSUSE Tumbleweed is paving the way for that future, while already being "the reliable rolling release". The talk will dispel the fears, uncertainties and doubts that many have regarding rolling releases in general and Tumbleweed specifically, and share how you can get involved both using, and improving, this exciting fast moving foundation of the openSUSE Project. But not everything is perfect. This talk will also identify some rough edges in Tumbleweed and suggest collaborative solutions as to how the openSUSE Project could start addressing them, so we can continue the exceptional progress Tumbleweed has made into the future and beyond the year 2020. about this event: https://c3voc.de Fri, 26 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1322-eng-How_I_Learned_to_Stop_Worrying_and_Love_Tumbleweed_but_Still_Occationally_Worry_sd.mp4?1495820061 9CM1MrBw8tVaEJyoQlRW3g 2017-05-26T00:00:00+02:00 Richard Brown No osc17, 1322 Everyone should be running a rolling release, and we should keep making it better Rolling Releases are the future of Linux distributions.

Trying to decide which Linux distro to use for a new datacenter deployment. I was starting to question my old solid choice, CentOS, and decided to go with SUSE. Join me as I go over my journey to SUSE, and why I am now convinced that it is the best Linux Distro out there today. Also see how I am convincing people to switch to SUSE and abandon the old ways of Linux for the chameleon. about this event: https://c3voc.de Fri, 26 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1392-eng-My_Move_to_SUSE_sd.mp4?1495813901 y51b5xL9m5uzZtXF7dFzLw 2017-05-26T00:00:00+02:00 Thomas S Hatch No osc17, 1392 A little over a year ago I found myself doing the Distro Dance.

Since then we have regularly heard rumours about it. Have they now switched back to proprietary software again or not? Didn't they already migrate back last year? Is it a trend that public administrations aren't using Free Software anymore? Have we failed and is it time to get depressed and stop what we are doing? Do we need new strategies? Those are questions people in our community are confronted with. We will shed some light on those questions, raise some more, and figure out what we -- as the Free Software community -- can learn from it. about this event: https://c3voc.de Fri, 26 May 2017 00:00:00 +0200 https://cdn.media.ccc.de/events/osc/2017/h264-sd/osc17-1458-eng-Limux_the_loss_of_a_lighthouse_sd.mp4?1495813659 wtIryX0wXoJwm3FKr4PRZw 2017-05-26T00:00:00+02:00 mk_fsfe No osc17, 1458 Started in 200X the Limux was often cited as the lighthouse project for Free Software in the public administration.
