At RubyWorld Conference 2010 in Matsue I gave a talk (06.09.2010) about I use Ruby during my daily Job of building Radio Systems for Mass Transit Projects.
This is one of the talks for the sub-event "World Wide Ruby Conferences" (27.08.2010) during RubyKaigi 2010 in Tsukuba about the European Ruby Conference (EuRuKo).
