Wie funktionieren Webseiten?

Frauen in die MINT-Berufe – das Thema ist präsent in allen Medien. Wir fangen ganz vorne an und beginnen am 27. April mit dem Girls’ Day. Alexander vom Team Application Operations hat dafür Inhalte zum Thema “Wie funktionieren Webseiten?” zusammengestellt. Es freut uns, dass sich zu unserem ersten Girls’ Day gleich zwei Mädchen angemeldet haben. Es wird ein spannender Tag.

Weitere Informationen zur Veranstaltung (ausgebucht) gibt es auf den Seiten des Girls’ Day.

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.

S3 outage: more diversity needed

The latest Amazon S3 outage showed me one thing again: more diversity is better.

Diversity is a current topic that includes social issues like women in tech. However, on a technical basis diversity also is important. It’s known that monocultures are more affected by diseases and other issues. So when half of the internet is using Amazon, a lot goes down if Amazon fails.

Every system will eventually fail. This is true for Amazon, as well as us. The internet is moving fast away from independent, interconnected nodes to an oligopoly. Nobody gets fired for using AWS nowadays. And that’s a problem I think. We need to embrace independent providers for the better of the internet.
