Blocking Facebook using /etc/hosts

harrymc is close but for some reason OS X (as of 10.8.2) doesn't respect the IPv6 loopback address of ::1 (probably a bug), so you have to use fe80::1%lo0. The reason you need to block IPv6 is because Facebook will serve you their site over V6 if your ISP supports it. You can easily verify this by installing a browser plugin that displays an icon when a site is being served via IPv6. The reason this wasn't a problem for you before is because Facebook likely only recently started serving their site over IPv6.

So the correct answer is:

# Block Facebook IPv4
127.0.0.1   www.facebook.com
127.0.0.1   facebook.com
127.0.0.1   login.facebook.com
127.0.0.1   www.login.facebook.com
127.0.0.1   fbcdn.net
127.0.0.1   www.fbcdn.net
127.0.0.1   fbcdn.com
127.0.0.1   www.fbcdn.com
127.0.0.1   static.ak.fbcdn.net
127.0.0.1   static.ak.connect.facebook.com
127.0.0.1   connect.facebook.net
127.0.0.1   www.connect.facebook.net
127.0.0.1   apps.facebook.com

# Block Facebook IPv6
fe80::1%lo0 facebook.com
fe80::1%lo0 login.facebook.com
fe80::1%lo0 www.login.facebook.com
fe80::1%lo0 fbcdn.net

Recovering recent Microsoft Office files despite closing the default notification

If you were interrupted before you ever got the chance to save your PowerPoint file, you can simply look for it in the Microsoft Unsaved Files folder. Go to the File tab, make sure you're on Recent and click on Recover Unsaved Presentations. The icon is right below the list of folders under Recent Places.
