Started in 200X the Limux was often cited as the lighthouse project for Free Software in the public administration. 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 de...

The functional programming language "Haskell" has been instrumental in researching the design of compilers, type systems, and advanced programming language features for more than 2 decades, but in recent years it has also become increasingly popular with red-blooded software engineers who worry about practical tasks like developing client/server systems, standalone applications, cryptography, f...

presented by Tobias Mueller

The keysigning problem helps to strengthen the Web of Trust which is the decentralised PKI in the OpenPGP world. 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 ...

presented by Wolfgang Engel

SUSE Package Hub is a project to collect openSUSE packages built for SUSE Linux Enterprise in a central repository. 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. M...

Applying small updates is normally no problem in a running system. 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 qu...

There many reasons why, when it was first introduced in 2001, the original Apple iPod got so popular. 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 prod...

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 resul...

Having a project that builds nicely in OBS is one piece of the story. Taking it into the openSUSE Distribution is a different thing. On last years oSC the Leap release manager (Ludwig) approached me 'Why dont you bring GNU Health into Leap'? Yes, why not? I liked the idea, but had not enough time to spend for the project. When the first RC was announced, we had to speed up....and finally mad...

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...
