Meet the organizers: Paweł Pacana

Does “disk utilization”, “IOPS” or “disk latency” say something to you ? How about “io-wait” or “slab cache” ? I was also not familiary with many of them unitl I met Paweł. The thing is: sometimes when we deal with high level stuff, acceptance testing, business value of project, DCI, MVC drama, we tend to forget that our applications run on raw hardware in real operating systems. Not enough RAM, full disk, starving disk, memory leaks, open files limits, all of them can make your beautifuly written application useless unless you know what caused the problem and how to fix it. That’s why it is so good to have Paweł in the team. He is not only a great Rails and Event Machine developer but also has a proper understanding on how some decisions (such us database, http server, application server, programming model) will affect performance and scalabilty of the overall solution. Paweł is our “self-proclaimed community manager” with highest number of talks given on DRUG, and “+1” achievments on our irc channel.
