On 11 August 1987, Apple released the “software erector set” HyperCard at Macworld Expo in Boston, and while it hasn’t been with us for many years now, back then it made a huge difference in the lives of Mac users, enabling many to give life to ideas that would otherwise never have seen the light of day. That might include even TidBITS, since we published our first 99 issues in HyperCard format, in a stack that could import its content into a searchable archive. Without the thrill of publishing in an entirely new format, it’s possible that TidBITS might have fallen by the wayside.

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.
