Containerised Application technologies like AppImage, Snappy and Flatpak promise a brave new world for Linux applications, free from the worries of shared libraries and dependency issues. 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 resurrect...

Libabigail is an infrastructure for semantic analysis of ELF binaries containing C or C++ programs. 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 t...

The Legal Review happening in the Factory development process is a black box for many, even though it's very important for keeping openSUSE away from danger. But many only know the downside of this requirement: if the review takes "too long". This presentation is trying to shed light into the black box and show the processes and applications used. Explaining the challenges and pitfalls - and the a...

We often have the impression that while we keep working things don't seem to get solved. In this presentation we will discuss the development process, then will go over what the KDE community has been up to in terms of QA and will bring some ideas so that we can create, together, better solutions. about this event: https://c3voc.de

Most software engineers use kanban boards for task management, often these are physical boards using post-it notes. These physical boards are often great for visibility and enjoyable to use. However they are very disconnected from the digital side of the software development world. What if we could use moving physical kanban cards to update our digital systems, bridging our physical and digital wo...

Whenever you are curious about how sources become an installable software in Leap without additionnal repository, or think about contributing to openSUSE project with some packaging stuff, this talk will retrace the journey of gcompris-qt package from its upstream source to the final package that will be natively available in openSUSE Leap 42.3. I will explain in details the different steps to fol...

Like every year, the last session will be a meeting with the openSUSE Board. about this event: https://c3voc.de

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. 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-a...

This talk will explain how the KDE packages were prepared and submitted to Package Hub so SLE users could enjoy them. Missing dependencies, rpmlint complaining about valid packages, not fully available dependencies, missing branding packages... It wasn't an easy path to travel but it was worth it. This talk will explain the problems found and how they were solved with the hope to make it easier fo...

Do you work on an open source project? 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...

DevOps is one of the Industry's great buzz words. 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 wh...

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 dep...

The data center is getting bigger and more complex, and the microservice revolution is creating even more moving parts with application stacks that may contain hundreds and thousands of containers and services. 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...

A tour on what's new in the YaST world, all the way from the high level view down to some interesting technical details. The talk includes an introduction to quite some new cool stuff and a review on what is being dropped or improved. There will also be an open discussion on how several features implemented in YaST to support SLE can open new possibilities for openSUSE. about this event: https://c...

Performance testing is very important in various different deployments and scenarios however in the NFV (Network Function Virtualization) it is even more meaningful. With a growing umbrella of projects and hence infrastructure NFV and SDN represent a very complex environment to test and, as a result, to give the correct interpretation to figures gathered through performance testing. Is my result g...

This talk will give you introduction to Sigfox network and show differences between Sigfox and other IoT networks. It will also demonstrate examples on how you can process collected data. Live demo will be displayed on stage. about this event: https://c3voc.de

OBS provides a wide range of feature that help packagers to ship their software to their users. This talk is showing some of the key features of OBS and how they help packagers to make their life easier.
