Would a Quad Core chip help with compiling applications -- or would it be the same as a dual core or single core chip running at the same clock speed because the compiler is running single thread? Again, it depends. If you have to compile a lot of C files via a Makefile without much interdependencies you could start make with the -j 8 flag so it can start 8 jobs concurrently. (The number of cores x 2 seems to be the best option). Would php processing be benefited by quad a quad core over a dual core. If not, then I guess I should just purchase a dual core chip and save the cabbage up front and wattage to boot. It could very well benefit. It depends where the bottleneck is in your current setup. It e.g. depends on how many apache and php instances you have running, and how you have compiled apache. Apache 22 is standard compiled with the prefork MPM, which starts 2 processes by default, and can start up to 16 IIRC (both numbers are configurable). A quad processor could make this run faster as long as the rest of the system can keep up.

Really high quality pneumatic tools (industrial grade) can be completely disassembled, cleaned, and repaired. The consumer grade stuff usually can't. In large shops, the usual procedure is to distribute the air with really long runs of pipe and put water traps at the end - that's probably what your thinking of with a drier. The traps fill up and every once in a while you open their petcocks and they pee old sock-smelling water out on your shoes. With a small pancake compressor it is generally satisfactory to run it without a drier, and at the end of the day, pour a couple teaspoons of air tool oil into the tool air intake then reconnnect the airline and give it a puff to distribute the oil.

You can The story I read was that the Chinese companies decided to get into making electrolytic caps a number of years ago. They sent spies into the Japanese companies to steal the electrolyte formula. Unknown to them the Japanese had anticipated this and so each batch of electrolyte was secretly treated with a stabilizer chemical that only the top chemists in the company knew about. The production chemists were unaware of it. When the Chinese firms stole the electrolytic formula, they produced caps that lacked this stabilizer. The result was the electrolyte broke down and the cap split. I don't know if it's a true story or not, but it sounded good!

If you live in the US and would like a server-class Supermicro PDSMi+ board (just the board, although I could throw in some memory if you'd like), I have a spare which I could give to you for free. I just upgraded my home FreeBSD box to an X7SBA, so the older PDSMi+ sits in its box (I purchased it retail, so it comes with manual, cables, etc.). These boards retail for about US$240, and work very well with FreeBSD.
