OSDir.com, run by the O’Reilly network, has put together the 2003 Editor’s Choice Awards in Open Source.  There is an award for best application by language:

• Java: Eclipse
• Perl: Movable Type
• Python: Bit Torrent
• PHP: PHP, looks like they couldn’t decide here
• XML: Jabber

Then they award best software by application, and finally ‘best new apps’.
