I'm American, not Japanese, but in case you're curious, I run WinXP for web browsing and such, but I use FreeBSD 4.10 for development. I do everything from the command line. I use Textpad on windows to edit source files, and I upload them and then build them on the freebsd machine. I use the GUI stuff I like, and I get to backup everything as part of the process as well. It's nice to have seperate "work" and "build" machines, since I usually push my "work" machine pretty hard with all the multi-tasking I'm doing. The FreeBSD machine is more or less dedicated to builds. Ruby programming doesn't usually involve a build step, but I've carried the habit over anyways, so that I can ensure cross platform compatibility. FreeBSD is better for me because I like the way everything seemlessly works together. I prefer the minimalist approach whenever it ensures smoother operation. Linux is too "busy" for me, and I hate fixing problems. Robert Oschler wrote: > Does anybody know what the dominant O/S for Japanese Ruby users is?
