While it can't compete with its older and more powerful sibling BBEdit, TextWrangler from Bare Bones Software continues to provide cash-strapped users with a solid text editor. The latest version, 3.1, has hit the Internet's shelves with a long list of improvements and fixes. At the top are a new Unix command for searching across multiple files from the command line, the capability to create new files and folders on remote servers from within the embedded FTP/SFTP browser, and a new Unlearn Spelling command for when misspellings have accidentally been added to the dictionary. Also, many minor bugs have been fixed, including a handful of crashing bugs related to reading certain gzip files, opening the Multi-File Search window, and closing the Multi-File Search window after selecting certain search sources. The full and lengthy list of changes is available on the Bare Bones Web site. (Free, 12.1 MB)
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
