By now FOSDEM turned into some kind of tradition in our family: Since 2007 every year in February we are travelling to that one comfy B&B in Brussels for a weekend - not to take a closer look at the city but to attend (together with thousands of other geeks and open source hackers) one of the biggest conferences on all things open source.

I love the conference concept for scaling: As it happens on a university campus they only have a limited number of huge rooms, but a fairly large number of mid-sized and small rooms. They use the venue to their advantage: Only the main tracks are organised by the official conference organisers. All other rooms are each filled with a community (usually a handful of people doing the heavy lifting of inviting speakers, putting a cfp out etc.) provided track. As a result even though they attract well over 5000 attendees it's only the most popular topics (e.g. Elasticsearch, GPL license discussions, configuration management, JDK specifics, kdbus, discussions on the relevancy of distribution packaging) tend to fill rooms completely.

When stuck with full rooms there's always some other talk on that probably is similarly interesting. In addition there is a huge exhibition area to visit where you can talk to the core developers behind the individual open source projects (and buy stuff like T-Shirts, grab a few flyers, stickers etc.). In addition there's so many people to talk to you usually won't get to see too many presentations anyway. In addition as of this year the crazy people of the FOSDEM (formerly Debian-only) video team managed to get (on a best effort, "hopefully the technician doesn't sleep in after that many beers yesterday" basis) all 445 talks video-taped with the goal of putting these online Monday after the conference.

On top I had the huge advantage of being able to simply follow to the talks my husband would go to if all of the stuff I am interested in is full: That would give me insight to completely different topics but also make it extremely easy for me to identify the good speakers and interesting presentations based on his experience avoiding the "if I'm unfamiliar with the topic and area I usually bump into the boring, badly given talks" problem.

I spent most of Saturday in a few talks on software patents, Daniel Naber's Language Tool, the Jolla BoF, the FLA. The rest of the time I caught up with the FSFE (thanks again for the bringing the onesies!), Debian, Open Office, Lucene and Elasticsearch people. The day ended at the Jolla community dinner - with a waitress that was completely overwhelmed by the number of geeks wanting food, beer and soft drinks.

Sunday I started with Chris Kühl's talk on Memory Tuning Android for Low Memory Devices. After that I helped at the Elasticsearch booth - FOSDEM definitely is an incredibly busy event. But given their target audience also is an interesting mix of people to talk to: Some had no idea about how text search works but came over because they had heard about Wikipedia using the project for search and wanted to know more. Some had a very clear idea of how they could benefit from Lucene for their NLP projects and wanted to know more on how that fits with Elasticsearch. Others were switching from Solr Cloud and needed some advise on how the systems compare for their particular use case. Others again were using Elasticsearch to analyse log files in a distributed fashion and needed advise on how to implement some feature. There was this one guy from Debian I've known ever since helping at the FSFE booth at Chemnitzer Linuxtage back in 2008 I believe who wanted to know more about Elasticsearch because one of his fellow package maintainers had been volunteered to work on the Elasticsearch RFP (#660826 if you are interested in reading more).

Overall (as every year) a really pleasant experience. What was in particular interesting this year was to meet people I knew only from completely other contexts (CCC events, system administrators, core Apache httpd people). Seems like FOSDEM is not only growing bigger but also more diverse.

The only kind of feedback I would provide is to split some dev rooms by finer grained topics to parallelise and scale even better (the Java, NoSQL and configuration management ones come to my mind first but there probably are others as well - of course again this depends on room availability and actual community members volunteering to submit a dev room related to their project in particular).

I'm glad I'm travelling home by train like last year - not only does that give me time to code and write the blog post you are reading just now, it's also comfortable to get rid of the usual sleep deprivation :)
