FOSDEM 2012 ...

Last weekend FOSDEM 2012 took place at the area of the Université libre de Bruxelles (ULB) - and it's been the first time I've been there. All in all it's been a great and well-organized conference with lots of interesting talks - unfortunately with many interesting ones in parallel ... so, I've missed a lot of them. Here are the talks I've attended.

• On Saturday:
• Ensuring uptime in a small startup: A good talk about some principles on how to ensure uptime during schema updates - based on PostgreSQL, but applies to any relational database.
• An introduction to Ada 2005 and Ada 2012: A time shift back into my days at the university - at least concerning the presentation style: good didactics and very old-style slides. I've never coded in Ada. So, this talk gave me a rough introduction.
• Why Java for Linux Applications?: A very personal talk about the speaker's learnings when trying to develop a GUI for an existing set of programs - and why he failed with C and Gtk+ ending up with Java and Swing.
• Debian packaging for beginners: As I'm working a lot with RPM packaging and have never done packages for Debain-based systems so far, this talk was a good introduction for me.
• Linux Containers and OpenVZ: Nothing really new for me, but a good overview of the current state and the upcoming features.
• Garbage Collection Visualization, GCSpy and NetBeans in tandem: I expected a bit more hands-on, as I spent a lot of time on GC optimization for various JVM scenarios. But GCSpy seems to be a project worth looking at in the near future.

• On Sunday:
• Sphinx Users stories and How to offload MySQL server with Sphinx: Very interesting for me, as I'm using Sphinx for enabling fast full-text search on email data stored in a MySQL database.
• MySQL HA reloaded - old tricks and cool new tools to guarantee high availability to your MySQL Servers: A good and surely quite complete overview about the possibilities to ensure MySQL high availability and their limitations.
• Works with persistent graphs using OrientDB: A short and hands-on introduction into OrientDB.
• Bringing monitoring into the 21st century - How to predict problems before they arise: A good talk about adaptive monitoring and why fixed thresholds can be misleading.
• DevOps is not an absolute. It's a range.: A really cool talk about the different nuances of DevOps inspired by real-world experiences.
• The Apache Cassandra storage engine: Not so interesting for me, as I've never used Cassandra before.
• Configuration management and deployment with RPM and YADT: The project I'm partially working on for my current employer. A colleague of mine held this talk and made a good job.

Besides the talks there were many booths from a lot of vendors and organizations.
