Absolutely great tutorial on installing ruby and rails on the raspbrry pi:

I already mentioned this, but it’s worth repeating: It took 23 minutes to write the SD card, and there was no feedback along the way. This wasn’t a big deal since I had been pre-warned by one of the wikis. apt-get needed an update before I could install git. $ sudo apt-get update did the trick. The Pi will do absolutely nothing without a properly configured SD card. You know how a PC will partially boot (to CMOS) even without a hard drive? Not so with the Pi. The micro-USB power port requires 700mA or more of current. Most micro-USB power adapters deliver 500mA or less. Raspberry Pi will only boot if the micro-USB provides sufficient amperage. Only one of my several micro-USB adapters met this requirement. A 4GB SD card is far too small if you want to do something useful with the Pi.
