InterNews Caveats -- A number of people wrote in response to my InterNews review to note that it isn't as fast as Nuntius and cannot display (though it can save) text after the first 32K, which causes problems with long messages such as the Info-Mac Digest posted in comp.sys.mac.digest (but TidBITS sneaks in, since it's almost always less than 32K). A few bugs were flushed out by the release, and Roger Brown said that he's working on fixing them, so keep an eye out for an update this fall.
Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.
