GeeCON (http://2014.geecon.org/) - one of the biggest Java (and JVM in general) conferences in Poland will take place in Kraków on May 14-16th.
Many people will come here day before in the evening, and will look for somebody to hang out, to drink some beer and to nerd around. :)
So, let's meet in some pub, drink some beers and talk about CQRS and DDD! (Command Query Responsibility Segregation principle and Domain-Driven Design - for those, who are not aware. ;) )
We will meet in "House of Beer" pub: http://www.houseofbeerkrakow.com
Just ask about the reservation for "cqrs".
If you are NOT a member of this meetup group, join us in the pub anyway! :)
