MIT Uses Machine Learning Algorithm To Make TCP Twice As Fast 250

An anonymous reader writes "MIT is claiming they can make the Internet faster if we let computers redesign TCP/IP instead of coding it by hand. They used machine learning to design a version of TCP that's twice the speed and causes half the delay, even with modern bufferbloated networks. They also claim it's more 'fair.' The researchers have put up a lengthy FAQ and source code where they admit they don't know why the system works, only that it goes faster than normal TCP."

US Sentinel Drone Fooled Into Landing With GPS Spoofing 647

McGruber writes "Following up on the earlier Slashdot story, the Christian Science Monitor now reports that GPS spoofing was used to get the RQ-170 Sentinel Drone to land in Iran. According to an Iranian engineer quoted in the article, 'By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain.' Apparently, once it loses its brain, the bird relies on GPS signals to get home. By spoofing GPS, Iranian engineers were able to get the drone to 'land on its own where we wanted it to, without having to crack the remote-control signals and communications.'"

LHC Scientists Create and Capture Antimatter 269

Velcroman1 writes "Scientists at the Large Hadron Collider have created antimatter in the form of antihydrogen, demonstrating how it's possible to capture and release it. The development could help researchers devise laboratory experiments to learn more about this strange substance, which mostly disappeared from the universe shortly after the Big Bang 14 billion years ago. Trapping any form of antimatter is difficult, because as soon as it meets normal matter — the stuff Earth and everything on it is made out of — the two annihilate each other in powerful explosions. 'We are getting close to the point at which we can do some classes of experiments on the properties of antihydrogen,' said Joel Fajans, a University of California, Berkeley professor of physics, and LBNL faculty scientist. 'Since no one has been able to make these types of measurements on antimatter atoms at all, it's a good start.'"

3D Printing May Face Legal Challenges 316

angry tapir writes "A coming revolution in 3D printing, with average consumers able to copy and create new three-dimensional objects at home, may lead to attempts by patent holders to expand their legal protections, a paper from Public Knowledge says. Patent holders may see 3D printers as threats, and they may try to sue makers of the printers or the distributors of CAD (computer-aided design) blueprints, according to digital rights group Public Knowledge."

Where Are the Original PC Programmers Now? 124

Esther Schindler writes "In 1986, Susan Lammers did a series of interviews with 19 prominent programmers in a Microsoft Press book, Programmers at Work. These interviews give a unique view into the shared perceptions of accomplished programmers, the people who invented the tools you use today. In Programmers Who Defined The Technology Industry: Where Are They Now?, I tracked down the fate of these prominent developers — from Robert Carr (Framework) to Dan Bricklin (VisiCalc) to Toru Iwatani (author of Pac Man, I'm glad you asked). The article quotes the developers' 1986 views on programming, the business, and the future of computing. In two cases (Bricklin and Jonathan Sachs, author of Lotus 1-2-3) I spoke with them to learn if, and how, their views had changed. One meaty example: In 1986, Bill Gates said, on Microsoft's future: 'Even though there'll be more and more machines, our present thinking is that we won't have to increase the size of our development groups, because we'll simply be making programs that sell in larger quantities. We can get a very large amount of software revenue and still keep the company not dramatically larger than what we have today. That means we can know everybody and talk and share tools and maintain a high level of quality.' At the time, Microsoft had 160 programmers."

Building a Telegraph Using Only Stone Age Materials 238

MMBK writes "It's the ultimate salvagepunk experiment, building a telegraph out of things found in the woods. From the article: 'During the summer of 2009, artist Jamie O’Shea of the organization Substitute Materials set out to test whether or not electronic communication could have been built at any time in history with the proper knowledge, and with only tools and materials found in the wilderness of New Jersey.'"

One Step Closer To Speedier, Bootless Computers 249

CWmike writes "Physicists at the University of California at Riverside have made a breakthrough in developing a 'spin computer,' which would combine logic with nonvolatile memory, bypassing the need for computers to boot up. The advance could also lead to super-fast chips. The new transistor technology, which one lead scientist believes could become a reality in about five years, would reduce power consumption to the point where eventually computers, mobile phones and other electronic devices could remain on all the time. The breakthrough came when scientists at UC Riverside successfully injected a spinning electron into a resistor material called graphene, which is essentially a very thin layer of graphite. The graphene in this case is one-atom thick. The process is known as 'tunneling spin injection.' A lead scientist for the project said the clock speeds of chips made using tunneling spin injection would be 'thousands of times' faster than today's processors. He describes the tech as a totally new concept that 'will essentially give memory some brains.'"

MIT Unveils Portable, Solar-Powered Water Desalination System 117

An anonymous reader writes "A team from the Massachusetts Institute of Technology's Field and Space Robotic Laboratory has designed a new solar-powered water desalination system to provide drinking water to disaster zones and disadvantaged parts of the planet. Desalination systems often require a lot of energy and a large infrastructure to support them, but MIT's compact system is able to cope due to its ingenious design. The system's photovoltaic panel is able to generate power for the pump, which in turn pushes undrinkable seawater through a permeable membrane. MIT's prototype can reportedly produce 80 gallons of drinking water per day, depending on weather conditions."

Disc-Free Netflix Streaming Arrives For the PS3 and Wii 188

tkdog writes "Netflix has added Sony's PlayStation 3 and Nintendo's Wii to the list of devices that can stream their catalog's content without the need for a disc. On the Netflix blog, VP Greg Peters adds, 'In addition to removing the need for discs, we've developed a new user interface on both applications that significantly improves the experience. The new applications will allow you to search for content directly from the device and you'll also be able to view an increasing portion of our content library with subtitles or alternate audio tracks.'"
