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.

Digital Photography: Correction & Follow-up

Send Article to a Friend

Digital Photography: Correction & Follow-up -- I would like to point out a mistake in my article "Sense & Sensors in Digital Photography" in TidBITS-751. I stated that smaller sensors are more sensitive to camera movement than larger sensors, but when the field of view is comparable, they are not. This vitiates one paragraph but has no effect on any conclusions or advice. Also, an editing gaffe at the end of the same article sowed some confusion over the role of green in Bayer sensors. The second link below points to a clarification of this and also to an extensive set of FAQs that have come out of the series. [Charles Maurer]
