SETI Brings Space Exploration to Home Macs -- The SETI (Search for Extraterrestrial Intelligence) project is now offering a Macintosh version of its SETI@home client, an idle-time screen saver application that crunches data collected from the Arecibo radio telescope in 340K "work units" downloaded from SETI's servers. Faced with an enormous amount of data collected (about 35 GB per day), SETI is hoping that the search for distant communication signals will be speeded by the distributed computing power of thousands of personal computers. The SETI@home client, a 210K download, can be run as a screen saver or stand-alone application and requires a PowerPC-based system with at least System 7.5.5 and 32 MB of RAM. We've always looked for intelligence within the Macintosh and Internet worlds; now you can help us search for signs of intelligent life elsewhere in the universe by joining the SETI@home TidBITS team. Just visit the second URL below and sign up so the work your Macs do with the SETI@home client is registered with our team. [JLC]
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.
