Multiple Santas -- The Internet Multicasting Service has also set up a Christmas-oriented Web site, complete with a <email@example.com> address and a number of interesting Web pages. This Web site has a Cyberspace Christmas Campaign, in which several corporations, including Sun Microsystems, have agreed to donate thousands of dollars to charities of their choice. The catch is that the donations come in dime-sized increments, one for each time someone on the Internet browses the Web pages associated with those charities. So, for instance, to receive the full $25,000 promised by Sun, the Second Harvest Food Bank pages must be viewed 250,000 times; otherwise Sun gets the unused portion of their money back in early January. Browse early and often. [ACE]
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.
