Difference: ProgrammingBookmarks (42 vs. 43)

If you're trying to use a non-default ssh key with git (e.g. for github) then this will help: http://help.github.com/multiple-keys/

You can store your "dotfiles" in git, too, which is especially great now that we do so much work inside virtual machines. There seem to be two schools of thought:

• make a git repo in $HOME and include/exclude the files that you care about (e.g. http://psung.blogspot.com/2008/06/managing-dotfiles-with-git-continued.html, http://www.charlietanksley.net/philtex/dotfiles-and-git-take-2/)
• make a git repo in a subdirectory and sync from there up to $HOME (e.g. https://github.com/ryanb/dotfiles)

I'm trying the first approach. It seems less complex.

Setting up a new machine looks like:

$ cd
$ git init .
$ git remote add caboteria ssh://user@host/path_to_repo/dotfiles.git
$ git fetch caboteria mitre:caboteria/mitre
$ git checkout -fb mitre caboteria/mitre
