Mac OS X 10.1.3 Released -- Apple has released the Mac OS X 10.1.3 update as a 17.3 MB download via Software Update. (If you're running Mac OS X 10.1 or 10.1.1, a separate 38.4 MB combined update to 10.1.3 is available.) As with previous updates to Mac OS X, this one is well worth getting, and kudos to Apple for providing decent release notes. Along with reliability improvements, Mac OS X 10.1.3 includes more drivers for CD burners and digital cameras, enables DVD playback on external VGA displays connected to PowerBook G4s, turns video mirroring on by default when a PowerBook connects to a new display, and offers improvements to iTunes with full screen visualizers. Networking security received attention as well, with login authentication support for LDAP and Active Directory services, an update to OpenSSH 3.0.2p1, WebDAV support for Digest authentication, and support for SSL encryption in Apple's Mail application.

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.
