OpenBSD Gains Centrino Power Management
In a recent email, Theo de Raadt announced support in -current for power management on the Pentium M series of processors. This allows the CPU to be throttled and therefore power saved. Additionally, dhclient was modified so that it is not necessary to find the process of the already-running dhclient and kill it before running dhclient again. This is useful for laptops that spend time roaming between different wireless networks, when dhclient is used fairly often.
The XP ACPI implementation is much, much further along than the Linux's is, or may ever be. When implemented fully, ACPI can do all sorts of nifty things like shutting down individual peripherals to save power, even if they're on the USB bus (do a search for "usb 'selective suspend'" and see how many hits for Linux you get), throttle the CPU (now superceded by SpeedStep et. al), etc. Also, as much as I hate to admit it, Unix simply was never designed with this type of role in mind. It takes tons of tweaking to get a Unix system to mimic the same basic features found out-of-the-box in Windows, things like HDD spindown, intilligent CPU throttling (cpudynd does not count), etc. Even then everything is wont to thrash your disk with reckless abandon
I think there is a world market for maybe five personal web logs.
