CodeMash: Have .NET in your Java
Disregarding the cool although a rather brutal name, CodeMash aims to demystify the different development platforms' practices and methodologies and maybe put an end(or at least minimize) the ".NET is better than Java or Ruby is better than .NET" crap by very passionate platform developers and instead learn from each other's platform.
From the site itself:
What is CodeMash?
CodeMash is a unique event that will educate developers on current practices, methodologies
and technology trends in variety of platforms and development languages such as
Java, .NET, Ruby and PHP. Held January 18-19, 2007 at the lush
Kalahari resort in Sandusky, Ohio, attendees will be able to attend a world-class
technical conference amid Ohio's largest indoor waterpark. So nobody will frown
if you show up in shorts, sandals, and your loudest t-shirt. You might even win
a prize for doing so.
