Telestream has released an update to its powerful screencasting application ScreenFlow. The new version increases the time limit for YouTube videos to 15 minutes (instead of 10) and corrects several other issues with exporting video. These and other bug fixes come just a few months after the 2.1 release of ScreenFlow, which added the capability to create all-in-one Flash video - including the video itself, the Flash player, and the necessary HTML - along with 64-bit audio capture support and automatic document saving. You can try the software for free, but exported movies will be watermarked. ($99 new, free update, 8.2 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.
