Not much to write about tonight, so I'll take the lazy way out and just link to something.

I don't use Little Snitch myself, but a lot of folks do. An article on Ars Technica explores Little Snitch 2.0 beta, the latest upgrade to this popular outbound firewall.

Little Snitch listens on your computer's network connection for outbound connections to remote hosts, and alerting you so you can make decisions about what your computer connects to. There's a lot of new features packed into this release, including a complete UI overhaul, network monitor, and more.
