Jeff Russell's Starship Dimensions - a must visit for geeks. I wished it had more ships.
Via Lifehacker: DivShare - upload and share your files. No bandwidth limit. I fail to see a revenue model so I predict that they'll disappear relatively fast but until then it is very nice (no ads, no need to create an account)
Windows Spy - a handy little Spy++ like tool. If you need to debug some window issues and you don't have Spy++ available
What do you do when DNS Stuff is down? You try AjaxDNS (via Ajaxian) - the interface is confusing (it took me some time that I had to enter the site in the upper right corner) and isn't nearly as advanced as DNSStuff. Also, there is no real advantage in using AJAX here (other than the cool factor). It actually was faster for me to look in the help of nslookup than to figure this interface out.
The first videos from 22C3 started appearing
