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)
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
