SCALA DAYS 2012 17-04-12

scala days 2012

Scala Days 2012 is a fantastic and unique occasion to meet with Scala-using professionals and companies, to exchange ideas and form business relations, as well as to discover the latest practical and theoretical development concerning the Scala language.

A central part of the Scala Days event will be the Third Scala Workshop, a forum to showcase and discuss a wide range of cutting-edge Scala research projects. In addition to the Workshop, further Scala Days sessions will be devoted to technical talks, experience talks, and tool demonstrations, offering a comprehensive insight on all that is going on in the Scala world. We have also planned social lunches a Scala Bus Routemaster tour of London and a Scala Days Dinner, which will offer further opportunities to meet and discuss with all the people that matter in the Scala world in a relaxed social context.
