Release 2017_010 with many security updates

During the last weeks we have prepared a larger update for our Gentoo based VMs. It will include many basic libraries as well as added support for Python 3.5 and 3.6. A detailed list of affected packages and changes can be found as usual in our ChangeLog. Please review the list of updated packages for libraries and tools that may have compiled into your applications. While we have tried to avoid link-level compatibility issues, a small chance remains that applications will not start afterwards due to dynamic linkage problems. Recompiling usually  solves this kind a problem.

As the update is a bit bulky, we opted for a staged roll out during the week. Each VM will get an individual scheduled maintenance slot according to the agreed pre-announcement period. Development and staging VMs will already receive updates during this weekend.

Please feel free to contact our support if you need assistance.

Internal and External Interfaces From an Operations Perspective (long read)

We recently pitched for a project that explicitly asked for a team with experience dealing with a system that has many interfaces. I sat down and wrote an overview of our experience and what we learned about internal and external interfaces over time – and I’d like to share this in today’s post.

Retrospection: Flying Circus at CLT2017

The Chemnitzer Linux Tage is a venue which needs no big introduction I guess. Connecting the (mostly) German Linux and open source enthusiasts for almost two decades now is a big achievement and a great event to catch up and meet people in #rl (real life). As we did in the last years we try to continuously make some kind of effort in participating, be it as lecturer, sponsor or having workshops.  This year we decided to introduce Vulnix, a tool for detecting potential vulnerabilities on running systems or nix-driven projects. I wrote about it here and there.
