So, you just did a git reset --hard HEAD^ and threw out your last commit. Well, it turns out you really did need those changes. You’ll never be able to implement that algorithm that perfectly twice, so you need it back. Don’t fear, git should still have your commit. When you do a reset, the commit you threw out goes to a “dangling” state. It’s still in git’s datastore, waiting for the next garbage collection to clean it up. So unless you’ve ran a git gc since you tossed it, you should be in the clear to restore it.

Seen on a git 1.6.0.4 installation (dunno about previous versions), installed through MacPorts

+bash_completion option.

Josh Knowles recently suggested that maybe I could merge grb’s functionality to the github gem.

Both gems being command-line tools that help you use Git in a friendlier manner, the question makes a lot of sense. It makes so much sense in fact, that I decided to blog about it. A post about it will scale much better to answer other users who may potentially ask the same question.

To install any ruby gem which has a command-line interface on Ubuntu 8.10, you have to add a path to your PATH environment variable. In your .bashrc file, add the following line:

export PATH=$PATH:/var/lib/gems/1.8/bin

Also worth noting is the fact that the default ruby interpreter on 8.10 is back to the 1.8 branch: it’s 1.8.7 (1.9 was the default on 8.04 iirc). 1.9  also be installed right besides 1.8.
