So I'm trying to get some ruby code a friend of mine wrote running on my laptop, but it segfaults every time I fire it up. After a little debugging, it looks like FXRuby is the culprit, and the behavior is trivially reproducible by typing require 'fox16' in to irb. I'm running OS X and my friend runs Linux, but anecdotally this code wo...

I'm using Rice to write a C++ extension for a Ruby gem. The extension is in the form of a shared object (.so) file. This requires 'mkmf-rice' instead of 'mkmf', but the two (AFAIK) are pretty similar. By default, the compiler uses the flags -g -O2. Personally, I find this kind of silly, since it's hard to debug with any optimization en...
I'm trying to write a script that will rename a computer and join it to a domain, and was planning to call on netdom.exe to do the dirty work. However, trying to run this utility in the script (same results in irb) does absolutely nothing. No output, no execution. I tried with backticks and with the system() method. System() returns fals...
