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.

Everyone should be running a rolling release, and we should keep making it better openSUSE Rolling Releases are the future of Linux distributions. 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.

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.

The history of quite some components still present in the current version can be tracked back to 1999. In 2013 the code was automatically converted from YCP, a purpose-specific procedural programming language, to Ruby, a general-purpose object oriented one. Since then, the YaST team has been trying to steady replace many YCP components and paradigms with new object-oriented, test-driven ones. In this workshop we will develop a new YaST module from scratch using the new Ruby-based approach. That is, object oriented dialogs and clients, CFA to modify the configuration files, Cheetah to execute system commands, RSpec tests and so on. Attendees are expected to be proficient with object oriented programming (preferably Ruby) and to have an recent openSUSE system (can be a virtual machine) to follow the workshop. Having read the YaST development tutorial in advance would definitely be a plus. YaST, the openSUSE beloved Swiss army knife, has been around since 1996.

It depends on people participating by signing other people's keys. However, when following best practises, the act of signing a key involves secure transfer of the OpenPGP key which contemporary casual key signing protocols for small groups address by exchanging the fingerprint of the key to be signed. The key will then be downloaded over an untrusted channel and the key obtained needs to be manually verified. We will see a less stressful approach to signing keys which makes it easy to sign a person's key. It enables very small groups of people to casually hold very small key signing parties. The key idea is to automatically authenticate the key material before the transfer via a secure audible or visual channel. A Free Software implementation of the protocol will be shown and people are invited to sign their keys :-) The keysigning problem helps to strengthen the Web of Trust which is the decentralised PKI in the OpenPGP world.

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?

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.

Not with the Open Build Service, the Free Software build and distribution system which powers openSUSE, ownCloud and Tizen! Usually a lot of manual work is necessary to create your custom Linux appliance, but the Open Build Service abstracts all the complicated technologies and makes this task as easy as pie. In this workshop, we will show you how we plug several open source technologies together to create Linux appliances in a fully automated, continuous integration cycle. Starting with a commit to your favorite version control system, the OBS will build a ready-to-use image of an operating system for you automatically, using the power of KIWI. And to finish the continuous integration cycle, openQA will run automated tests to make sure your appliance still works as expected. We will combine this workshop with the 'openQA beginners workshop' submitted by Marita Werner. This workshop will cover the package and image building process in OBS, the openQA part will be covered by the following workshop.

How do we move beyond the old patterns of configuration management and infrastructure as code to what's required to survive in a world of distributed systems? If application developers can write event-driven programs to listen and react to stimulus, why can't operators do the same for infrastructure? In this keynote Thomas Hatch, SaltStack technical founder and CTO, will discuss how to control modern data center complexity, and turn it to a competitive advantage, using SaltStack and SUSE technologies. Thomas will provide insight into the SaltStack model for event-driven infrastructure and the emerging framework for intelligent, responsive application stack management. Modern data center commodities have never been so ​diverse. From bare-metal to containers, Kubernetes to web servers, SaltStack and SUSE have solutions to bring order and peace of mind to a complex new world.

It's no secret that many AutoYaST configuration features can be implemented using some Configuration Management System (like Salt or Puppet). So the idea is to bring together the best of both worlds: AutoYaST will take care of installing the base system (partitioning, networking, etc.) and Salt will configure the system. During this talk, attendees will see the module in action and will get into the nitty-gritty details as well. Of course, we'll also have a look at experimental features, like Puppet support or SUSE Manager Salt Formulas integration. Last but not least, we would love to hear more ideas from you and discuss your use case. YaST2 Configuration Management is a brand new YaST module which offers integration between AutoYaST and Salt.

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.

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.

Many of the optimizations are targeting the networking stack which is becoming a bottleneck as the traffic traverses from the hypervisor to the virtual machine and vice versa. As a result of which, improving the components that sit in-between is normally the first thing to look at. One such component is Open vSwitch whcih is a popular virtual switch heavily used in OpenStack. Another component is the Data Plane Development Kit (DPDK).

The syslog-ng application collects logs from many different sources, performs real-time log analysis by processing and filtering them, and finally it stores the logs or routes them for further analysis. In an ideal world, all log messages come in a structured format, ready to be used for log analysis, alerting or dashboards. But in a real world only part of the logs belong to this category. Traditionally, most of the log messages come as free format text messages. These are easy to be read by humans, which was the original use of log messages. However, today logs are rarely processed by the human eye. Fortunately syslog-ng has several tools to turn unstructured and many of the structured message formats into name-value pairs, and thus delivers the benefits of structured log messages. Once you have name-value pairs, log messages can be further enriched with additional information in real-time, which helps responding to security events faster. One way is adding geo-location based on IP addresses. Another way is adding contextual data from external files, like the role of a server based on the IP address or the role of the user based on the name. Data from external files can also be used to filter messages, for example to check firewall logs to determine whether certain IP addresses are contained in various black lists for malware command centers, spammers, and so on. Logging is subject to an increasing number of compliance regulations. PCI-DSS or many European privacy laws require removing sensitive data from log messages. I will demonstrate how logs can be anonymized in a way that they are still useful for security analitics. At the end I would like to introduce you to the basics of syslog-ng configuration, and demonstrate how the collected logs can be used for alerting or visualized on a dashboard.

Whereas upstream application authors have always had the possibility to offer downloads for Windows and macOS, distributing packages for Linux has traditionally required a lot of additional duplicated effort from maintainers, and does not scale well beyond the core set of applications that are part of the distributions. Lately, application bundle formats like AppImage, Flatpak, and Snap have gained popularity in the Linux world, with Linux Torvalds calling AppImage "just great" and users appreciating the ease of the "one app = one file" concept. Providing an application in AppImage format can have many advantages: - Just one format for many major distributions like openSUSE, Ubuntu, Fedora, CentOS, Debian, and others - Super simple for users: just download one file, make it executable, and run - No unpacking or installation necessary - No root needed - No system libraries changed - Works out of the box, no installation of runtimes needed - Optional desktop integration with `appimaged` - Optional binary delta updates (only download the bytes that have changed between builds) - GPG signatures (inside the file) - Works on Live ISOs and when booting into multiple different distributions On the flipside, it has been argued that distributing application bundles places additional burden on upstream application authors, who now also need to keep the bundled libraries up-to-date. Tools used by distributions can greatly mitigate this, by ensuring reproducible, up-to-date builds from trusted sources. In this talk, Open Build Service lead developer Adrian Schröter and AppImage lead developer Simon Peter illustrate the challenges around providing quality application bundles and how they can be solved by using proven distribution methodologies such as those provided by the Open Build Service. http://speakerdeck.com/probonopd/opensuse-conference-2017-obs-b-appimage http://speakerdeck.com/probonopd/opensuse-conference-2017-obs-b-appimage Speakers: Simon Peter, AppImage Adrian Schröter, SUSE Providing desktop applications to multiple Linux-based target systems (distributions) can be cumbersome.

Even though it was simpler, it had fewer features and it was more expensive than other MP3 players in the market, people loved it and it sold like hotcakes. The main reason for its popularity was that it was a pleasure to use: easy, fast, intuitive. Unfortunately, compared to commercial products, a lot of the open source software out there is not very easy to use. A lot of OSS is built from the developer's perspective, without taking into account the user's experience. Too many buttons, unclear wording, and other faults play against the usability of OSS, reducing the number of people who will enjoy using it. The good news is that making software easy to use is not that difficult, and it doesn't require having Apple's budget. OSS developers just need to take usability into consideration when building the apps they want to share with the world. In this talk, I will give a short introduction to what usability is, explain the benefits that come from building usable software, and show how developers can increase the usability of their creations.

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.

This session will discuss how DevOps helps, what the pitfalls are, and how to avoid failure while squeezing the BEST out of DevOps. false craig gardner 2017-05-28T18:30:00+02:00 16:30 01:00 Saal (Main Hall) Long Talk 1456-annual-meeting-with-the-opensuse-board Annual Meeting With the openSUSE Board openSUSE Like every year, the last session will be a meeting with the openSUSE Board.

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.

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.

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?
