Last time I looked at LED stagelights about a year ago, the LED PAR64 can seemed to be a drop in replacement for 300W PAR56 lamps. Unfortunately, until intensity catches up to their higher wattage cousins, most of the stages I've worked on are going to keep dropping in 750W HPL, 1KW BVT, and 1K PAR64 lamps. The biggest advantage is its easier to get a blue of out an LED than a halogen, for obvious reasons, but losing the light among the other fixtures isn't really desired all the time.

My recent experience with trying to bring them into my department at work has been dissapointing. We had a Mac Pro (the big quad processor monster) die after four days. Ok, it happens, everything else has worked flawlessly. I even delt with the inevitable teasing about the siny new Mac being a lemon.
Well after almost four hours dealing with Apple Care, three hours dropping off and picking up my computer at different stores as per thier instructions trying to get this done quickly... I am beginning to wonder if Apple really wants business customers to rely on these machines. Much as I may dislike Dell like the rest of you... when my Linux box died it was fixed in four hours and I spent maybe 20 mintes of my time setting up the repair. I have spent seven hours of my time so far on this Mac and it still will not power up. Is this just me or have other people lost critical business machines to the depths of Apple Care inefficiency and lack of business level support?"

Levitating high-speed trains, super-efficient power generators and ultra-powerful supercomputers would become commonplace thanks to a new breed of materials known as high temperature superconductors (HTSC). "The breakthroughs in superconductivity bring us to the threshold of a new age," said the president. "It's our task to herald in that new age with a rush."

But 20 years on, the new world does not seem to have arrived. So what happened?'

Submission + - Lost Moon landing tapes discovered

Submitted by de_smudger on Monday January 15, 2007 @10:20AM

de_smudger writes: For years 'lost' tapes recording data from the Apollo 11 Moon landing have been stored underneath the seats of Australian physics students. A recent search has uncovered them.

Recorded on telemetry tapes, they are said to be the best quality images of the landing (unconverted slow scan TV) yet to be seen by a public still fascinated by the early space race. These tapes were mislaid in the early 1980s on their way to NASA's Goddard Space Flight Centre in Greenbelt, Maryland.

In my enthuseasm to buy a SMP machine in 2003 I overlooked the fact that my Tyan Tiger MPX (S2466) wasnt very popular as a workstation and would develop serious compatibility issues only four years in to its fifteen year useful life span. Fedora Core cannot be installed on the machine, nor can my existing installation support OpenGL graphics without crashing. (an issue with the GART chip which the kernel still claims to support — it stopped working about eight months ago). If I were to accept this loss, which workstation class boards can I choose which will remain operable under Linux for the entirety of their useful lifespan? Is it possible to obtain a guarentee with respect to a specific board that it will continue to be supported?"
