While small in terms of numeric progression, Audio Hijack Pro 2.10.1 from Rogue Amoeba adds some welcome new features. The latest release of this audio recording program includes the latest version of the Instant On component (5.0), which can now capture audio from sandboxed applications purchased from the Mac App Store. The Multi-Process mode, previously used in conjunction when pulling audio from several Web browsers, is now used for additional applications to improve audio capture. Finally, audio pulled from input devices can now be configured in Audio MIDI Setup instead of always using channels 1 and 2. ($32 new, free update, 5.2 MB, release notes)
Avoid Simple Typos
If, like me, you find yourself typing 2911 in place of 2011 entirely too often, you can have Mac OS X (either Lion or Snow Leopard) fix such typos for you automatically. Just open the Language & Text pane of System Preferences, click the Text button at the top, and then add a text substitution by clicking the + button underneath the list. It won't work everywhere (for that you'll want a utility like Smile's TextExpander), but it should work in applications like Pages and TextEdit, and in Save dialog boxes.
