After using Greymatter as the content management system for this site for a couple years, I wound up getting interested in what was going on under the covers. I never really cared before, because the script just worked. I had looked into it enough to know it was written in baby talk Perl, and not altogether well-optimized, but it functioned beautifully and never let me down.

Then a bunch of goofballs figured out a way to exploit a vulnerability in the way the script handled PHP tags. A clever person figured out that GM's combination of weak input validation and world-writeable directories makes it possible to do some fairly nasty things to someone with a .php extension who allows comments. So I patched up my copy (copies by then--I had a Greymatter 1.21b and a 1.21c running) once I caught wise to what was going on.

Here's a company that is doing business on the Internet the right way. At Lunar Accents, not only have they caught on to the LED lighting revolution, but they seem to have a good grasp of how the Internet works as well, a refreshing change from dealing with a typical electronics supplier.

"Presidents and generals feared it, the investors feared it, more or less everyone feared it that very night a few years ago. Billions had been spent on hunting it down, still no one had even caught a glimpse of it... until now."

If you haven't checked out mashie's latest project yet, you need to. It's a kickass biomechanical sculpture and of course it's a working PC too.

This press release came to my attention today announcing the availability of boards using the Nano-ITX form factor later this year. Wow, these things are 12cmx12cm, or about 4.5 inches square.

This article from AnandTech gives an exciting, thorough first look at the BTX form factor. Read the article, it's great, but I can also sum up some of the points it makes.

Become a Dremel Jedi; learn the techniques and tricks of cutting your case by adding a freestyle, low-profile window.

In this article, sparks fly as we put the Dremel rotary tool to our case panel. The Dremel tool is certainly not the only way to cut your case, but it offers a great deal of control and flexibility in experienced hands. Beginning modders ask more questions about the Dremel tool than almost anything else, so we'll take you through cutting a window. Along the way you'll meet the tool and learn the techniques that get professional looking results.

Give your machine the personal touch--improve its usefulness and appearance--and make it stand out in a crowd.

In this article, we look at two simple mods: a stealth blowhole and handles. Along the way we show you how to use templates and jigs to make your work look more professional. It seems simple enough to make a hole in your case and mount a couple of handles, but we'll teach you some advanced modding techniques, introduce you to some useful tools, and walk you through the steps to modifying your stock case. In future articles, we'll take the same case and subject it to many more modifications, and by the end of the series you won't recognize this beige refugee from the accounts receivable department--in its place will be a tricked out hot rod that you'd be proud to show off at your next LAN party.

I came up with this idea, tested it and implemented it a while back, but I never got around to writing the article. So here's the first new circuit article I've posted in well over a year. The basic idea is very similar to what Philips implemented with the Xitanium driver for Luxeon Star LEDs. It's a current-regulated driver, and there are a few design advantages over a voltage-regulated resistive approach. And it's cheap.

In response to reader feedback, let me also point out that this design is not optimized for efficiency, so it is probably not a circuit you would want to use to drive a Luxeon Star in a flashlight or other power-constrained environment. But for a lot of applications, this appropach works fine.

My jaw just dropped when I read Japala's original firewheel mod back in January. I had too much stuff going on to try it then, but I knew I wanted to do it.
