Slashdot Mirror

Michael Ashley writes "A paper published in Nature today reports on the exceptional astronomical seeing conditions at Dome C (Coral link) in Antarctica. Obtaining the data posed some significant technological challenges, given that Dome C is uninhabited over winter. The experiment was controlled by a PC/104 computer system that had to survive temperatures down to -85C, and supervise the generation of its own electricity using a jet-fuel powered stirling engine. The computer, running Linux, communicated with the outside world using an Iridium phone. The results are also covered in New Scientist, and the Sydney Morning Herald. Disclaimer: I'm a co-author."

Slashback tonight with word on the (groan) fate of Iridium, more Speak n' Spell modding, examples of Serial ATA oozing to market, the RIAA versus mandatory DRM, and more. Read on for the updates.

In this household, we obey the laws of physics! Tuesday before last, we mentioned that two scientists had announced what they claim is the first accurate measure of the speed of gravity.

Now, Emperor_Alikar writes "In an article on Space.com, many physicists have criticized the current work on the speed of gravity, calling it 'nonsense' and 'simply incorrect.' Many of them still doubt the claims made by Fomalont and Kopeikin even before the results were even announced. Many of the physicists still hold on to the idea that gravity works instantaneously no matter what the distance, an idea that originated by Newton, but that was argued against by Einstein."

Back from the back from the back from the dead. Checkers writes "Spacedaily.com posted the following two stories about Iridium today. The first story is about the DoD committing the first of three renewal options that will use Iridium through 2005. The second story related story is about an agreement inked between Iridium and Harris Corp. that allows Iridium the right to use Harris' OS/COMET satellite command and control system for the life of the Iridium satellite network."

E.T. was also into this scene. In re: matt simpson writes "Another fantastic Speak & Spell modder is Dave Wright of the band "not breathing". You can check his work out, among other modifications to toys, at www.carrionsound.com Dave has made speak & spell/math/read for Nine Inch Nails, Meat Beat Manifesto, and many other bands. Figured you might be interested in other neat synth hackers :)"

Further evidence, never a good time to buy. SpinnerBait writes "It's seems like Serial ATA Controllers have been on the market forever but where have all the Serial ATA Hard Drives been? The wait seems to finally be over, as HotHardware shows with this review and showcase on a pair of new Seagate Barracuda V Serial ATA drives. This article covers benchmarks with the product in single drive configurations, as well as RAID 0. In addition, they show performance on two different SATA controllers, from Promise and Silicon Image. And oh, those nice thin neat little SATA cables! Gotta love 'em."

We've had a few articles about Serial ATA; I hope it lives up to its reputation.

Just to add to the confusion ... probejockey writes "A current article in the Globe and Mail claims SCO will start collecting licensing fees from some Linux users, not all Linux vendors as previously reported here."

Birds of a feather, separate rooms. Finally, Declan McCullagh sent in a few interesting links yesterday regarding the RIAA and its announced opposition to mandated DRM technologies:

"First, here are the photos from today's press conference.

Second, the supposed news of today's announcement was that the RIAA would no longer pursue mandatory-DRM technologies like the Hollings bill. But it was the MPAA that was behind Hollings from the beginning (September 2001). And when Hollings finally introduced his bill in March 2002, it was the MPAA that endorsed it, while the RIAA pointedly did not."

Thanks to Declan for the links.

Wasn't smart enough to get in, either ... Finally, thanks to the several readers who alerted me by email and in comments that the school variously rendered Cal Tech, CalTech and other things even worse is in fact properly spelled "Caltech."

Using a data kit attached to an Iridium phone you can either dial up a modem, or use direct internet connectivity. Speeds are rather modest (9600bps) but there's plenty of applications where that'd suffice." OK. I would happily pay $300 / month even for 9.6kbps, if it was unmetered -- I could ride my BikeE the world around with a headmounted display, a twiddler, and a solar-charged laptop in the cargo bin. But prices are hard to find on the Iridium website, which means I can't afford it.

wtpooh writes "Wired has an article about a company developing a wind-up power source for computers. Apple is reportedly interested. " The company is also talking about its use in things like sub-notebooks. Man, if they made this (solar panels will probably be included), and if I got Iridium, I could go outside and still post. Seriously though, for people working the field, and less developed nations, things like this could really help the spread of computers.

Well, the first of the commercially availible satellite systems has been completed. Iridium's last birds in space went up late Tuesday on a Delta II rocket. The satellites have been confirmed and the whole operation will go online on Sept. 23. This is really cool stuff-now if someone would just loan me one of the phones-3500$USD-and while they are at, maybe some service as well. I could be a great beta tester. Honest.
