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]
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
