NVIDIA GeForce GTX 690 Benchmarked 119

MojoKid writes "NVIDIA has lifted the embargo on benchmarks and additional details of their GeForce GTX 690 card today. According to a few folks at NVIDIA, company CEO Jen Hsun Huang told the team to spare no expense and build the best graphics card they possibly could, using all of the tools at their disposal. As a result, in addition to a pair of NVIDIA GK104 GPUs and 4GB of GDDR5 RAM, the GeForce GTX 690 features laser-etched lighting, a magnesium fan housing, a plated aluminum frame, along with a dual vapor chamber cooler with ducted airflow channels and a tuned axial fan. The sum total of all of these design enhancements results in not only NVIDIA's fastest graphics card to date, but also one of its quietest. In the performance benchmarks, NVIDIA's new dual-GPU powerhouse is easily the fastest graphics card money can buy right now, but of course it's also the most expensive." The GeForce GTX 690 has been reviewed lots of different places today, Tom's Hardware and AnandTech to name a few.

Decades-Old Soviet Reflector Spotted On the Moon 147

cremeglace writes "No one had seen a laser reflector that Soviet scientists had left on the moon almost 40 years ago, despite years of searching. Turns out searchers had been looking kilometers in the wrong direction. On 22 April, a team of physicists finally saw an incredibly faint flash from the reflector, which was ferried across the lunar surface by the Lunokhod 1 rover. The find comes thanks to NASA's Lunar Reconnaissance Orbiter, which last month imaged a large area where the rover was reported to have been left. Then the researchers, led by Tom Murphy of the University of California, San Diego, could search one football-field-size area at a time until they got a reflection."

TI-Nspire Hack Enables User Programming 88

Posted by Soulskill
from the done-and-done dept.
An anonymous reader writes "Texas Instruments' most recent, ARM-based series of graphing calculators, the TI-Nspire line, has long resisted users' efforts to run their own software. (Unlike other TI calculator models, which can be programmed either in BASIC, C, or assembly language, the Nspire only supports an extremely limited form of BASIC.) A bug in the Nspire's OS was recently discovered, however, which can be exploited to execute arbitrary machine code. Now the first version of a tool called Ndless has been released, enabling users, for the first time, to write and run their own C and assembly programs on the device. This opens up exciting new possibilities for these devices, which are extremely powerful compared to TI's other calculator offerings, but (thanks to the built-in software's limitations) have hitherto been largely ignored by the calculator programming community."

Making music has never been quite this awesome! Using only ThinkGeek products (Bliptronic 5000, Guitar Shirt, Drumkit Shirt, Stylophone, and Otamatone Electronic Instrument) the ultra-geeks over at ThinkGeek have created this ultra-cool cover of The Who's Baba O'Reilly. This also qualifies as a full blown shameless plug since ThinkGeek shares a corporate overlord with Slashdot.

An anonymous reader followed up on the Windows memory-leak fraud scandal, which is worth reading before you read the perpetrator's justification. "Randall C. Kennedy comes clean about his past, his relationship to Craig Barth and how it all came tumbling down. Includes an inside look at the politics of IDG and why you can never trust an IT publication that's as obsessed with page views as InfoWorld."

Astronomers Discover the Coolest Known Sub-Stellar Body 60

Hugh Pickens writes "Science Daily reports that using the United Kingdom Infrared Telescope (UKIRT) in Hawaii, astronomers have discovered what may be the coolest sub-stellar body ever found outside our own solar system. Too small to be stars and with insufficient mass to maintain hydrogen-burning nuclear fusion reactions in their cores, 'brown dwarfs' have masses smaller than stars but larger than gas giant planets like Jupiter, with an upper limit in between 75 and 80 Jupiter masses. 'This looks like the fourth time in three years that the UKIRT has made a record breaking discovery of the coolest known brown dwarf, with an estimated temperature not far above 200 degrees Celsius,' says Dr. Philip Lucas at the University of Hertfordshire. Due to their low temperature these objects are very faint in visible light, and are detected by their glow at infrared wavelengths. The object known as SDSS1416+13B is in a wide orbit around a somewhat brighter and warmer brown dwarf, SDSS1416+13A, and the pair is located between 15 and 50 light years from the solar system, which is quite close in astronomical terms."

I wrote about:

"A receiver on Earth can then work out its position in three-dimensional space by comparing the arrival times of the signals from at least three satellites"

You commented "on earth".

Is it pedantic to point out that "in three-dimensional space" != "on earth" ?

But then again, this is /.
Some slippage is expected.

Or you could do something. I googled her name, found her web site, and left a message telling her about my opinion, and letting her know about my intentions not to vote for her, if she does not learn how to represent me.

If people would just do that, instead of venting here, our senator would do our bidding, instead of Hollywood's.

A few thousand angry comments would change her mind pretty quickly.

But, nae! That would be productive.
