Gentoo LiveCD for PowerPC G5
tantive writes with this announcement from the Gentoo home page. "Gentoo for PowerPC G5 now available. We're proud to announce the availability of the Gentoo for PowerPC G5
32-bit LiveCD. ISOs are now available on our
main OSU mirror. The LiveCD has been
tested on a dual 2GHz G5 SMP PowerPC machine with 2.5GB RAM, a 1.6GHz machine,
as well as others. It includes pre-released yaboot-1.3.11 bootloader and a
2.6.0-test9 benh kernel. It runs at 100% speed, with fans currently also
at 100% (kernel developers are working on slowing down the fans when not
needed)." Read more below.
The announcement continues "Installation is possible on the SATA drives. We are now hard at work to create optimized stages, and the store will carry G5 LiveCDs when stage building is finished. Right now you can bootstrap your own G5-optimized system, or use a generic ppc stage3 install with GRP to install Gentoo in 20 minutes. We would like to thank benh (PPC kernel developer) for his excellent work in supporting the G5, as well as all users who tested the ISO, and particularly IBM System Software researcher Eric Van Hensbergen, who provided fantastic test/debug help during the LiveCD development process."
Who modded this up? Only 9 fans in my G5.
The smells like a troll. Nothing like a personal anecdote to support one's opinion.
Sure, but again, why? The lastest MacOS X (10.3) comes with XFree86 4.3.0 as a supported binary.
IMHO, the biggest difference between MacOS X and a dual-boot Winux box is that you don't have to reboot the Mac to run Excel after you've been using GIMP. :-)

Some of the classic Cray supercomputers (Cray 2, Cray 3) used full immersion liquid cooling. The circuit boards and wiring of these machines lived in a bath of 3M Fluorinert. (Fluorinert is a nonconducting, noncorrosive liquid.) On the Cray 2, the circuit boards didn't even have solder masks - so the bare metal traces on the circuit boards were in direct contact with the liquid coolant - right along with the leads of the chips, pins on connectors, and everything else.) Also, a machine like the Cray 3 consumed power by the kilowatt (something like 80kW for a multiprocessor setup) - this level of power consumption actually boiled the liquid coolant. And yet, there were no problems with short circuits or electrocution :)
Purified water is actually a fairly good insulator. (It conducts very little electricity.) In fact, water purity is often measured by its electrical resistance in megaohms. (Typically tens of megaohms.) It is only when you add impurities to water that it starts to conduct electricity. (The water us mere mortal normally have to deal with - for example, "tap water" or rain water is not very pure. High purity water is sometimes used in scientific or manufacturing applications - an example would be water used as part of the manufacture process for integrated circuits.)
I don't know the details as to what type of liquid cooling is "regularly used in notebook computers" but I suspect what is being talked about are heat pipes. Heat pipes are essentially tubing filled with a liquid and a wicking material. One end of the pipe is attached to a heat generating component (like a CPU) and the other end of the pipe is attached to a thermal mass (heat sink) that can better dissipate the heat generated by the CPU. The advantage of this in a notebook computer is that you might not be able to locate the thermal mass in the same location the heat is generated, so heat pipes let you move heat around to areas where it can be dissipated.
You became part of the evil empire the minute you went into the apple store.
I don't think Linux has anything to to with that.
