Rogue Amoeba has updated its Airfoil network audio streaming app for the Mac to version 4.7.3, which now offers full support for receiving audio through Airfoil Speakers from devices running iOS 6. The Instant On component receives an update to version 6.0.2 to fix several unspecified issues, and the Airfoil Video Player has been fixed to avoid a crash on OS X 10.8.2. Additionally, audio can be captured from the WebKit application on Mountain Lion and Airfoil has been given an improved update process with automatic downloads and installation on quitting the app (via a newer version of Sparkle).

Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
