Git is a great distributed version control system that can be used to keep track of changes and code for any kind of project. Sometimes, it is helpful to configure a git server to house your team’s projects. Gitolite provides an access-control layer for a git server, so that you can configure user-based git access without the accompanying operating system user accounts.

GPG, or GNU Privacy Guard, is a public key cryptography implementation.

I once mentioned it to a classmate that I use GNU/Linux as the only Operating System at home, and he replied in shock, “That’s used by Hackers? Right?” That is true.
