My problem:
Made a small ROR application some moth ago, then got an IPS, then got the feeling that I have better learn to (I am used to windows) say command to a Linux machine. One thing was the ISP assumed that I was good at Linux, another that I had to install and use "Putty" () in order to issue commands to the server. Also a version-control-program runs only on Linux machine.
Then I stopped the project!

Do I have to be good also at Linux?
Can I ask Linux/"putty"/ROR related questions here?
The good Lenz (author the ROR book) has not commented these questions, as far as I remember.

Any comment here is more than really welcome.
