MeetBSD 2010 in California, USA.
The main reason for choosing these is because of technology they cover -
BSD, a Unix variant we utilize in our infrastructure.
As KyivBSD has passed, here is a short report on it. THe event was
held in Kyiv, capital of Ukraine (where company founders
grew up, and many FreeBSD users exist.) Apart from us, sponsors
include FreeBSD Foundation, iXsystems (both are also sponsoring
MeetBSD) and two other companies, V-Time (Ukrainian systems
integrator) and D-Link (well-known hardware manufacturer.)
The event took a full day, with eleven presentations, archived at
http://ru.kyivbsd.org.ua/
"FreeBSD on amd64" by Konstantin Belousov with detailed discussion of
platform's benefits, Andrey Gapon's talk on kernel debugging,
Alexey Cheusov's story about mk-configure - a new approach of
multi-platform build tool, inspired by BSD make,
and Nikolay Dzham's presentation of clusters on FreeBSD utilitizing
Sun (I mean, Oracle) grid computing engine.
My apologies for possible misspelling names, and big thanks to
Alexander Yerenkov who did great work of organizing this mini-conference.
