But I would really like to get RVM working as it ...

When I try to run it off the symlink, it doesn't work. I don't believe the issue is the $PATH, because pip, git, ipython all exist in this loc...
Hello, I was wondering if they was a way to prevent some commands from being executed in order to prevent from bad manipulation sometimes (for exemple you execute "rm *.py" when you wanted to execute "rm *.pyc" or something like that).

So every time the python app is adding the script, that script could be instantly available when the user is opening a terminal (eg. gnome-terminal). Wh...
I've been using R in Ubuntu to make system calls using system() for things like spinning up Amazon EC2 instances, managing files on S3, etc. If I start R from the command line everything works fine. But if I start R from a script using Rscript, or from ESS, I have issues with environment variables not being set. I think this is an issu...
