Several days ago, astalavista.com was torn down by an anti-security group. If you are not familiar with it, astalavista is a "security" community that discusses and hosts vulnerability information and exploits. The site appears to have been completely destroyed by attackers.
The attackers posted a text document detailing what they did on the site after they took it down. There is a copy of it hosted here. I went ahead and mirrored it here in case the other goes offline for whatever reason.
The details of the exploit itself are rather lacking. It appears to be some type of ...

I have put together a few examples of what this can be used to accomplish.

I've been planning on getting more familiar with git for several months. Yesterday, I watched the Google talk in which Linus Torvalds covered many of the advantages of the tool.
I use git for most of my personal stuff because distributed version control is certainly the simplest to use when there is only one person working on the project. It's extremely simple to create a repository. All you need to do is have git installed, and run a few commands.
That's about the extent of what I knew how to do with git. I could check things ...
