Comment Slow news day from what it sounds like... (Score 3, Informative) 203

TWT amps have been used in microwave systems since the 2nd world war. The use of TWT in satellites are recent, as in 25-30 years ago. The NSA's LACROSSE and the new ONYX satellites use TWT amps in the finals on their radar systems. The Soviet ROARSAT's probably use them as well, or something similar, they love to overbuild their stuff.

Hell, the YF-12a used 2 TWT's in tandem in its Hughes AN/ASG-18 radar, putting out over 10MW of raw power.

But they are power gobblers, The YF-12A's ate over 40KVA of juice to operate.

The Decline of the Landline 435

Death Metal writes "The phone network is thus not just a technical infrastructure, but a socioeconomic one. The more Americans abandon it to go mobile-only or make phone calls over the Internet, the more fragile it becomes: its high fixed costs have to be spread over ever fewer subscribers. If the telephone network in New York State were a stand-alone business, it would already be in bankruptcy. In recent years it has lost 40% of its landlines and revenues have dropped by more than 30%."

Up To 90 Percent of US Money Has Traces of Cocaine 441

mmmscience writes "Scientists have found that up to 90% of US paper money has some cocaine contamination, up from the 67% mark measured two years ago. Looking at bills from 17 cities, it's no surprise that the city with the highest level was Washington DC, where up to 95% of bills gathered there tested positive. From a global standpoint, both Canada and Brazil tested rather high (85% and 80%, respectively), but China and Japan were well behind the curve at 20% and 12%. The researchers hope that studies such as these will be of help to law enforcement agencies that are attempting to understand the growth and flow of drug use in communities."

Palm Pre Reports Your Location and Usage To Palm 314

AceJohnny writes "Joey Hess found that his Palm Pre was ratting on him. It turns out the Pre periodically uploads detailed information about the user to Palm, including the names of installed apps, application usage (and crashes), as well as GPS coordinates. This, of course, is without user consent or control. The only way he found to disable the uploads was to modify system files."

Man Jailed After Using LimeWire For ID Theft 241

angry tapir sends along this excerpt from PC World: "A Seattle man has been sentenced to more than three years in prison for using the LimeWire file-sharing service to lift personal information from computers across the US. The man, Frederick Wood, typed words like 'tax return' and 'account' into the LimeWire search box. That allowed him to find and access computers on the LimeWire network with shared folders that contained tax returns and bank account information. ... He used the information to open accounts, create identification cards and make purchases. 'Many of the victims are parents who don't realize that LimeWire is on their home computer,' [said Kathryn Warma of the US Attorney's Office]."

Voting Machine Attacks Proven To Be Practical 225

An anonymous reader writes "Every time a bunch of academics show vulnerabilities in electronic voting machines, critics complain that the attacks aren't realistic, that attackers won't have access to source code, or design documents, or be able to manipulate the hardware, etc. So this time a bunch of computer scientists from UCSD, Michigan, and Princeton offered a rebuttal. They completely own the AVC Advantage using no access to source code or design documents (PDF), and deliver a complete working attack in a plug-in cartridge that could be used by anyone with a few private minutes with the machine. Moreover, they came up with some cool tricks to do this on a machine protected against traditional code injection attacks (the AVC processor will only execute instructions from ROM). The research was presented at this week's USENIX EVT."

NASA Wants To Fund Space Taxis 136

NASA plans on using $50 million in stimulus funds to seed development of a commercial passenger transportation service to space. Potential space taxi inventors have 45 days to submit their proposals. The proposals will be competitively evaluated and the winners will be announced by the end of September. It is unclear what other Commodore 64 games NASA plans on making a reality, but I hope Arkanoid makes the short list.

CRIA, MPAA Demand Expanded DMCA For Canada 224

An anonymous reader writes "The Canadian Recording Industry Association and the MPAA's Canadian subsidiary are demanding that Canada adopt copyright laws that go beyond even the DMCA. The groups demand anti-circumvention law, three strikes and you're out legislation, and increased secondary liability for websites. The demands come as part of the national copyright consultation in which hundreds of Canadians have spoken out against such reforms."

A Standardized OS For Robots 184

Hugh Pickens writes "The New Scientist reports that at present, all robot software is designed uniquely, even for parts common to all robots but that could be about to change as roboticists have begun to think about what robots have in common and what aspects of their construction can be standardized, resulting in a basic operating system everyone can use. 'It's easier to build everything from the ground up right now because each team's requirements are so different,' says Anne-Marie Bourcier of Aldebaran Robotics but Bourcier sees this changing if robotics advances in a manner similar to personal computing where a common operating system allowed programmers without detailed knowledge of the underlying hardware and file systems to build new applications and build on the work of others. 'Robotics is at the stage where personal computing was about 30 years ago,' says Chad Jenkins of Brown University. 'But at some point we have to come together to use the same resources.' This desire has its roots in frustration, says Brian Gerkey of the robotics research firm Willow Garage. If someone is studying object recognition, they want to design better object-recognition algorithms, not write code to control the robot's wheels. "You know that those things have been done before, probably better," says Gerkey, who hopes to one day see a robot "app store" where a person could download a program for their robot and have it work as easily as an iPhone app."
