Rogue Amoeba has released Intermission 1.0.3, adding full support for OS X 10.9 Mavericks to the audio utility that enables you to pause and rewind up to 3 hours of live audio on your Mac. (If you’re not familiar with it, check out why Josh Centers is a fan in “FunBITS: Intermission Lets You Browse Your Mac’s Audio History,” 11 October 2013.) The update also resolves an issue where Bluetooth audio devices could cause static, improves compatibility with the Soundflower audio extension, and makes several unspecified small fixes.

Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.
