Codetown ::: a software developer's community
If your interested in playing with Java on Raspberry PI - another round of the "Oracle Massive Open Online Course: Develop Java Embedded Applications Using a Raspberry Pi" is starting May 19th. You can find more details and register here. Should be fun!
Register soon and be sure to get the required hardware in advance if you don't already have everything. They sell a prepackaged bundle, but looks like stock won't arrive for 15-20 business days (last I saw).
