Rise of the Small Botnet 61

wiredmikey writes "Botnets controlled by criminal enterprises all over the world continue to multiply at a steep rate, and it is now arguably the smaller, harder-to-trace operations that organizations should be the most worried about. Not only are smaller botnets cheaper and easier to build out and operate, but criminals have already realized that large-scale botnet activity attracts unwanted attention, and not just of law enforcement."

Grad Student Looking To Contribute To Open Source 283

An anonymous reader writes "I'm an Applied Math grad student who knows a bit of Mathematics and a bit of programming. C++ is my first programming language — I am decent at it. I wish to start contributing to a numerical library with two purposes — contribute to open source and develop my C++ skills at the same time. I looked at the Boost libraries and joined the developer list. However, I have no idea on how to start contributing. I'm not an expert in template programming, having written only toy programs to understand that concept. I've used some of the OOP constructs like inheritance,but only for very small projects. Do you have any tips on how to get started on contribution? Are there any other emerging numerical libraries to which I can contribute? Are there any other avenues where I can contribute to open source and improve programming skills?"

Burning Man Goes Open Source For Cell Phones 152

coondoggie passes along this excerpt from Network World: "Today I bring you a story that has it all: a solar-powered, low-cost, open source cellular network that's revolutionizing coverage in underprivileged and off-grid spots. It uses VoIP yet works with existing cell phones. It has pedigreed founders. Best of all, it is part of the sex, drugs and art collectively known as Burning Man. ... The technology starts with the 'they-said-it-couldn't-be-done' open source software, OpenBTS. OpenBTS is built on Linux and distributed via the AGPLv3 license. When used with a software-defined radio such as the Universal Software Radio Peripheral (USRP), it presents a GSM air interface ("Um") to any standard GSM cell phone, with no modification whatsoever required of the phone. It uses open source Asterisk VoIP software as the PBX to connect calls, though it can be used with other soft switches, too. ... This is the third year its founders have decided to trial-by-fire the system by offering free cell phone service to the 50,000-ish attendees at Burning Man, which begins today in Black Rock City, Nevada.

First Direct Photo of Exoplanet Confirmed 189

An anonymous reader noted a report confirming the first ever exoplanet actually photographed from telescopes on earth. Every other exoplanet so far 'observed' has been done by measuring wobbles of stars pulled by planetary gravity. But this one is a photograph. And that's just plain cool.

ASCAP War On Free Culture Escalates 335

An anonymous reader writes "After ASCAP declared war on free culture and Creative Commons responded on the incident, the war of words is escalating. Drew Wilson of ZeroPaid has been following this story closely. The EFF responded to the ASCAP letter, saying 'we don't think that ASCAP characterized EFF and its work accurately. We believe that artists should be compensated for their work, and one proposal we have for that is Voluntary Collective Licensing.' The response from the EFF came with a study and a letter written by one irate ASCAP member who donated to the EFF and to Public Knowledge as a result of the ASCAP letter. Public Knowledge also responded to the letter, saying, 'It's obvious that the characterization of Public Knowledge is false. Public Knowledge advocates for balanced copyright and an open Internet the empowers creators and the public. What we oppose are overreaching policies proposed by large corporate copyright holders that punish lawful users of technology and copyrighted works.' Now the National Music Publishers Association has weighed in to support ASCAP, saying that organizations like Public Knowledge and the EFF 'have an extremist radical anti-copyright agenda,' according to a transcript of a speech posted on Billboard. Public Knowledge has dismissed those allegations, saying 'anybody who has spent more than five minutes on our website or talking to our staff knows that these things are not true.'"

Scaling To a Million Cores and Beyond 206

mattaw writes "In my blog post I describe a system designed to test a route to the potential future of computing. What do we do when we have computers with 1 million cores? What about a billion? How about 100 billion? None of our current programming models or computer architecture models apply to machines of this complexity (and with their corresponding component failure rate and other scaling issues). The current model of coherent memory/identical time/everything can route to everywhere; it just can't scale to machines of this size. So the scientists at the University of Manchester (including Steve Furber, one of the ARM founders) and the University of Southampton turned to the brain for a new model. Our brains just don't work like any computers we currently make. Our brains have a lot more than 1 million processing elements (more like the 100 billion), all of which don't have any precise idea of time (vague ordering of events maybe) nor a shared memory; and not everything routes to everything else. But anyone who argues the brain isn't a pretty spiffy processing system ends up looking pretty silly. In effect, modern computing bears as much relation to biological computing as the ordered world of sudoku does to the statistical chaos of quantum mechanics.

ThinkGeek's Best Ever Cease-and-Desist Letter 264

ThinkGeek, sister company to Slashdot, received a meticulously researched (except on one point) 12-page cease-and-desist letter from the National Pork Board. What had the meat lobbyists up in arms was an April Fools product from the TG catalog: Radiant Farms Canned Unicorn Meat, whose copy included the line "the new white meat." The NPB figured this was confusingly similar to their trademarked "the other white meat" (an advertising slogan the pork industry is considering retiring anyway). Geeknet, parent company of Thinkgeek and Slashdot, issued a press release apologizing for any confusion; you can read it on ThinkGeek's site (PDF), because the newswires refused to distribute it for some reason. Oh, and ThinkGeek has no intention of taking down the protected parody.

DIY Synthetic Aperture Radar 118

An anonymous reader lets us know about a DIY synthetic aperture radar built for $240 in parts (give or take). Here's PDF slideware from the Ph.D. student's research. "Using a discarded garage door opener, an old cordless drill, and a collection of surplus microwave parts, a high resolution X-band linear rail synthetic aperture radar (SAR) imaging system was developed for approximately $240 material cost. Entry into the field of radar cross section measurements or SAR algorithm development is often difficult due to the cost of high-end precision pulsed IF or other precision radar test instruments."

Comment Wasn't this a Simpsons episode? (Score 1) 375

One from many seasons ago - when a giant comet was going to impact and presumably destroy Springfield. When it didn't happen (because it burned up in the atmosphere to the size of a Chihuahua's head), the townsfolk then shouted: "Let's go burn down the observatory so this never happens again!"

Parallel Programming For the Arduino 140

blackbearnh writes "As more non-traditional programmers start playing around with embedded platforms like the Arduino, the limitations and complications of interrupt-driven event handling can become an annoying barrier to entry. Now a group of academics have ported the parallel-processing language Occam to the Arduino. In an interview on O'Reilly Answers, Matt Jadud of Allegheny College describes how Occam helps artists using the Arduino in their installations, and how the advent of low-cost computing platforms is changing the educational experience for proto-makers in school. 'Basically, an artist or a tinkerer or a hacker has a goal. They don't really care about learning Occam. They don't care about how this language is different from C. They just want to make a cat door that keeps their cat out when the cat comes back with a mouse. Or they want to make some kind of installation piece. Trying to focus as much on the user and the possible goals they might have is what's motivating our work right now.'"

Cloth Successfully Separates Oil From Gulf Water 327

Chinobi writes "Di Gao, an assistant professor at the Department of Chemical and Petroleum Engineering at the University of Pittsburgh, has developed a method of separating oil from water within just seconds using a cotton cloth coated in a chemical polymer that makes it both hydrophilic (it bonds with the hydrogen atoms in water) and oleophobic (oil-repelling), making it absolutely perfect for blocking oil and letting water pass through. Gao tested his filter successfully on Gulf Oil water and oil and has an impressive video to demonstrate the results." This is a laboratory demonstration; the technology hasn't been tested at scale.

Artificial Cornea To Reach Patients This Year 94

kkleiner writes "A German-led team of researchers has developed a new version of an ophthalmological polymer to which the eye will bond and still function normally. 'The new polymer could help restore sight to thousands waiting for corneal transplants around the world. The artificial cornea has passed clinical trials and is ready to see expanded use in patients this year. ... In order to work in the human body, an artificial cornea has to meet some stringent requirements. First, it has to bond to the human eye around its edge. ... The center of the artificial cornea, however, does not promote cell growth and remains clear so that it can be seen through. The artificial cornea also has to move freely with the eyelid and balance moisture on its faces.'"

Voyager 2 Speaking In Tongues 260

dangle sends in an update from the borderland of Sol. "Voyager 2's flight data system, which formats information before beaming it back to Earth, has experienced a hiccup that has altered the pattern in which it sends updates home, preventing mission managers from decoding the science data beamed to Earth from Voyager 2. The spacecraft, which is currently 8.6 billion miles (13.8 billion km) from Earth, is apparently still in overall good health, according to the latest engineering data received on May 1. 'Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later,' said Voyager project scientist Ed Stone of the California Institute of Technology in Pasadena. 'It has already given us remarkable views of Uranus and Neptune, planets we had never seen close-up before. We will know soon what it will take for it to continue its epic journey of discovery.' The space probe and its twin Voyager 1 are flying through the bubble-like heliosphere, created by the sun, which surrounds our solar system."
