Many of you will remember the fanfare and bravado surrounding Sun Microsystems' Sep. 2004 announcement of a $1 per hour per processor utility computing plan. What you won't remember is Sun revealing a single customer using the service. That's because it hasn't. More than one year since it first started hyping the "pay-for-use grid computing services" Sun is still weeks away from presenting a customer to the public. The program has proved much tougher to sell that Sun ever imagined.

"A file system is something which computer users hear about all the time, but many do not know very much about. This article is going to be a short guide, which goes over the basics of file systems so you will at least know enough to get by. This is a subject which can get as complicated as you want to make it, but a little knowledge can go a long way."

Writing programs that generate other programs may seem esoteric, but once you learn why metaprogramming is so powerful, it's a skill you'll want to cultivate. This article explains why you might consider metaprogramming and looks at some of the components of this art.

"DR-DOS released DR-DOS 8.1 in the beginning of this month. But instead of an upgrade of the previous DR-DOS 8.0, it's something completely different. The kernel is a badly patched copy of the Enhanced DR-DOS kernel old version 7.01.06 without any credit to its author Udo Kuhnt. The other programs and drivers included are old versions of some popular open source, freeware and shareware products without licenses, documentation or even credit to their authors. This means that DR-DOS 8.1 is just a bunch of old tools plus a compilation of others' works, obviously sold without permission and in violation of their license terms."

"It's almost mind-boggling that every 18 months or so, regular as clockwork, you can get twice as much computing power. In fact, it is mind-boggling, and these high octane servers can cause some hassles in the data center. In this tip, I explore the standard fixes applied when server shoppers go overboard. These include server consolidation and grid computing. Then, I explore another option: virtualization with Xen."
