InterNews Caveats -- A number of people wrote in response to my InterNews review to note that it isn't as fast as Nuntius and cannot display (though it can save) text after the first 32K, which causes problems with long messages such as the Info-Mac Digest posted in comp.sys.mac.digest (but TidBITS sneaks in, since it's almost always less than 32K). A few bugs were flushed out by the release, and Roger Brown said that he's working on fixing them, so keep an eye out for an update this fall.
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.
