Yesterday/Today I have been testing out Google App Engine, just for some fun you know. It's actually pretty cool. It lets you develop online web apps in Python 2.5/2.7 Go (also a pretty neat language with no real purpose other than to write quick programs, you'll like it if you like Rust) and Java. It has all sorts of support, it even has support so people can log in with they're gmail accounts. Im currently writing an app so kids from my school can share our homework.
Post things you do with it!
