v.what? -- A typo bit us in last week's issue. The article on the PSI PowerModem incorrectly said that the modem uses v.32 error correction and v.32bis compression - those numbers should be v.42 error correction and v.42bis compression. Sorry for the confusion - the modem supports the v.32 and v.32bis communication protocols, which define the connection speed (9,600 bps or 14,400 bps), but are different from the error correction and compression protocols.
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.
