Twitter has released TweetDeck 2.1, an update that adds a smattering of features to the company’s column-based client. The new release adds support for photo and player cards (the latter of which can play video and audio), plus it enables you to edit and refine search columns using the new column options (click the magnifying glass icon at the top of a column). It also adds the capability to type “n” to start a new tweet and press Command-Enter to send a tweet. Also included are fixes for Retina display support and profiles that didn’t load under certain circumstances. (Free, 1.4 MB)
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
