Twitterers who don’t fear Adobe Air may be intrigued by news of the release of TweetDeck 0.37.3. New in version 0.37.2 is support for deck.ly, TweetDeck’s new, semi-ridiculous system for allowing tweets longer than 140 characters (the 0.37.3 version, currently available only via direct download from TweetDeck’s Web site, adds an option in the preferences to turn off deck.ly). More satisfying is the software’s added support for Instagram image previews. Also new is an upgraded version of the Squiggly spellchecking library. The update fixes several bugs, too: problems where punctuation in searches prevented them from working, a bug with Facebook’s login screen, and an issue with Twitter lists not updating properly.

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.
