It seems like just yesterday Microsoft's Channel9 PDC coding challenge finished only to be followed by numerous Visual Studio related contests. Now we even have MSN, Web services and Windows Vista contest. It's a great season for developers who have some free time and are competitive. Let's see:

1. Larkware coding contest, build something using Visual Studio 2005 (RC just came out) by the launch date (November 7^th) and you could win several expensive developer software packages
2. MSN Messenger world's best app, if you have l33t DHTML skills build something using Messenger Activity API and you could win a cool Alienware laptop and Visual Studio 2005 Professional
3. Microsoft/Amazon Web Services Developer contest, build something cool using Visual Studio 2005 and Amazon Web Services and you could win $5000
4. NewsGator API developer competition, use NewsGator API to build a cool app and you could win a cool Dell/Mac laptop
5. Virtual Earth competition, use Virtual Earth API and build something cool and you could win $1000
6. The Code Master challenge, build a Windows Vista app and win a piece of $125000 (!) in prizes; not all details are known yet and contest starts beginning 2006

Whew. If I had 48 hour days I guess I'd manage to build something for at least some of these :). I did compete in Channel9 challenge and am most likely to participate in Larkware coding contest, still undecided about the rest.
