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]
Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
