For Christmas I got a wonderful present: a 1GB USB drive. Now I feel the need to fill it with Ruby goodness, but I don't know exactely what to put on it. Basically I need a portable development enviroment that can be used with OSX, Linux and Windows. Windows could be bypassed by putting a bootable minimal live linux distribution on the drive, but then I could find myself on a box that can't boot from a usb drive (I have two of them at home :)). I was thinking about: Reference Documentation: Pickaxe2 PDF (that you too should buy!), rails doumentation, who knows what else An editor for each platform: TextMate (Mac), and don't know what to use on win/linux Ruby in its various forms Everything else. Obviously I don't know or I wouldn't have asked :) I think that 1GB should be more than enough for every ruby developer so suggest everything you have in mind :)
