Here are technologies we are actively using in our projects.
Quick, name the one language you wouldn't be without... That would probably be Groovy. Groovy is “a better Java”. It adds dynamic features to Java, and significantly reduces boilerplate.

In the past we have used C, C++, C#, Perl, Delphi and Visual Basic
Years ago we adopted Mercurial, transferring from CVS and SVN.
More recently we have started to move to Git.

We have used Apache and IIS.
Content Management Systems
