Conference has drawn very interesting speakers and international crowd – from Finland (naturally), Sweden, Poland, Germany, Russia and other countries. I made a few notes from selected talks on the conference.
Chris Wanstrath / GitHub (@defunkt)
- Slides: http://www.slideshare.net/err/inside-github
- Linus Trovalds Google tech talk about git – where Linus tell you that you’re stpid if you’re not using git
- rack-mobile-detect – is used by GitHub, super useful if you’re planning to create mobile optimized version
- GitHub uses Unicorn as an application server – personally I’m not sure if that’s better than Apache + Passenger. Chris tells that Unicorn is cool, because does fair load balancing on Linux kernel level, also Rails are loaded only once – and then required number of processes are forked – and this is very fast, a lot faster than loading rails separately for each Mongrel. And when one of the processes dies – there’s no need to re-load Rails, but just fork another process.
- GitHub doesn’t use delayed_job anymore since they needed several queues with different priorities – so far they use resque, but are considering developing a real queue management system
