Developers Disclose Schematics For 50-1000 MHz Software-Defined Transceiver

Wed, 02/25/2015 - 7:06pm
Bruce Perens writes Chris Testa KD2BMH and I have been working for years on a software-defined transceiver that would be FCC-legal and could communicate using essentially any mode and protocol up to 1 MHz wide on frequencies between 50 and 1000 MHz. It's been discussed here before, most recently when Chris taught gate-array programming in Python. We are about to submit the third generation of the design for PCB fabrication, and hope that this version will be salable as a "developer board" and later as a packaged walkie-talkie, mobile, and base station. This radio is unique in that it uses your smartphone for the GUI, uses apps to provide communication modes, contains an on-board FLASH-based gate-array and a ucLinux system. We intend to go for FSF "Respects Your Freedom" certification for the device. My slide show contains 20 pages of schematics and is full of ham jargon ("HT" means "handi-talkie", an old Motorola product name and the hams word for "walkie talkie") but many non-hams should be able to parse it with some help from search engines.

3 Million Strong RAMNIT Botnet Taken Down

Wed, 02/25/2015 - 6:45pm
An anonymous reader writes The National Crime Agency's National Cyber Crime Unit worked with law enforcement colleagues in the Netherlands, Italy and Germany, co-ordinated through Europol's European Cybercrime Centre, to shut down command and control servers used by the RAMNIT botnet. Investigators believe that RAMNIT may have infected over three million computers worldwide, with around 33,000 of those being in the UK. It has so far largely been used to attempt to take money from bank accounts.

US Govt and Private Sector Developing "Precrime" System Against Cyber-Attacks

Wed, 02/25/2015 - 6:05pm
An anonymous reader writes A division of the U.S. government's Intelligence Advanced Research Projects Activity (IARPA) unit, is inviting proposals from cybersecurity professionals and academics with a five-year view to creating a computer system capable of anticipating cyber-terrorist acts, based on publicly-available Big Data analysis. IBM is tentatively involved in the project, named CAUSE (Cyber-attack Automated Unconventional Sensor Environment), but many of its technologies are already part of the offerings from other interested organizations. Participants will not have access to NSA-intercepted data, but most of the bidding companies are already involved in analyses of public sources such as data on social networks. One company, Battelle, has included the offer to develop a technique for de-anonymizing BItcoin transactions (pdf) as part of CAUSE's security-gathering activities.

Artificial Intelligence Bests Humans At Classic Arcade Games

Wed, 02/25/2015 - 5:23pm
sciencehabit writes The dream of an artificially intelligent computer that can study a problem and gain expertise all on its own is now reality. A system debuted today by a team of Google researchers is not clever enough to perform surgery or drive a car safely, but it did master several dozen classic arcade games, including Space Invaders and Breakout. In many cases, it surpassed the best human players without ever observing how they play.

Intel Updates NUC Mini PC Line With Broadwell-U, Tested and Benchmarked

Wed, 02/25/2015 - 5:00pm
MojoKid writes Intel recently released its latest generation of NUC small form factor systems, based on the company's new low-power Broadwell-U series processors. The primary advantages of Intel's 5th Generation Core Series Broadwell-U-based processors are better performance-per-watt, stronger integrated graphics, and a smaller footprint, all things that are perfectly suited to the company's NUC (Next Unit of Computing) products. The Intel NUC5i5RYK packs a Core i5-5250U processor with on-die Intel HD 6000 series graphics. The system also sports built-in 802.11ac Wi-Fi, Gigabit Ethernet, USB 3.0 and USB 2.0, M.2 SSD support, and a host of other features, all in a 115mm x 111mm x 32.7mm enclosure. Performance-wise the new 5th Gen Core Series-powered NUC benchmarks like a midrange notebook and is actually up for a bit of light-duty gaming, though it's probably more at home as a Home Theater PC, media streamer or kiosk desktop machine.

The Peculiar Economics of Developing New Antibiotics

Wed, 02/25/2015 - 4:40pm
HughPickens.com writes Every year at least two million people are infected with bacteria that can't be wiped out with antibiotics but the number of F.D.A.-approved antibiotics has decreased steadily in the past two decades. Now.Ezekiel J. Emanuel writes at the NYT that the problem with the development of new antibiotics is profitability. "There's no profit in it, and therefore the research has dried up, but meanwhile bacterial resistance has increased inexorably and there's still a lot of inappropriate use of antibiotics out there," says Ken Harvey. Unlike drugs for cholesterol or high blood pressure, or insulin for diabetes, which are taken every day for life, antibiotics tend to be given for a short time so profits have to be made on brief usage. "Even though antibiotics are lifesaving, they do not command a premium price in the marketplace," says Emanuel. "As a society we seem willing to pay $100,000 or more for cancer drugs that cure no one and at best add weeks or a few months to life. We are willing to pay tens of thousands of dollars for knee surgery that, at best, improves function but is not lifesaving. So why won't we pay $10,000 for a lifesaving antibiotic?" Emanuel says that we need to use prize money as an incentive. "What if the United States government — maybe in cooperation with the European Union and Japan — offered a $2 billion prize to the first five companies or academic centers that develop and get regulatory approval for a new class of antibiotics?" Because it costs at least $1 billion to develop a new drug, the prize money could provide a 100 percent return — even before sales. "From the government perspective, such a prize would be highly efficient: no payment for research that fizzles. Researchers win only with an approved product. Even if they generated just one new antibiotic class per year, the $2-billion-per-year payment would be a reasonable investment for a problem that costs the health care system $20 billion per year." Unless payers and governments are willing to provide favorable pricing for such a drug, the big companies are going to focus their R&D investments in areas like cancer, depression, and heart disease where the return-on-investments are much higher.

Star Wars-Style "Bionic Hand' Fitted To First Patients

Wed, 02/25/2015 - 3:57pm
schwit1 writes "Three Austrians have replaced injured hands with bionic ones that they can control using nerves and muscles transplanted into their arms from their legs. The three men are the first to undergo what doctors refer to as "bionic reconstruction," which includes a voluntary amputation, the transplantation of nerves and muscles and learning to use faint signals from them to command the hand. Previously, people with bionic hands have primarily controlled them with manual settings."

It's Official: NSA Spying Is Hurting the US Tech Economy

Wed, 02/25/2015 - 3:16pm
An anonymous reader writes China is backing away from U.S. tech brands for state purchases as NSA revelations, according to Reuters, which confirms what many US technology companies have been saying for the past year: the activities by the NSA are harming their businesses in crucial growth markets, including China. From the article: "A new report confirmed key brands, including Cisco, Apple, Intel, and McAfee -- among others -- have been dropped from the Chinese government's list of authorized brands, a Reuters report said Wednesday. The number of approved foreign technology brands fell by a third, based on an analysis of the procurement list. Less than half of those companies with security products remain on the list."

Inventors Revolutionize Beekeeping

Wed, 02/25/2015 - 2:55pm
wombatmobile writes For more than 5,000 years, apiarists donned protective suits and lit bundles of grass to subdue swarms of angry bees while they robbed their hives of precious, golden honey. Now two Australian inventors have made harvesting honey as easy as turning a tap — literally. Cedar Anderson and his father Stuart have just been rewarded for a decades worth of inventing and refining with a $2 million overnight success on Indiegogo. Their Flow Hive coopts bees to produce honey in plastic cells that can be drained and restored by turning a handle, leaving the bees in situ and freeing apiarists from hours of smoke filled danger time every day.

Google Now Automatically Converts Flash Ads To HTML5

Wed, 02/25/2015 - 2:33pm
An anonymous reader writes "Google today began automatically converting Adobe Flash ads to HTML5. As a result, it's now even easier for advertisers to target users on the Google Display Network without a device or browser that supports Flash. Back in September, Google began offering interactive HTML5 backups when Flash wasn't supported. The Flash-to-HTML5 conversion tools for the Google Display Network and DoubleClick Campaign Manager created an HTML5 version of Flash ads, showing an actual ad rather than a static image backup. Now, Google will automatically convert eligible Flash campaigns, both existing and new, to HTML5."

The Groups Behind Making Distributed Solar Power Harder To Adopt

Wed, 02/25/2015 - 1:09pm
Lucas123 writes: Distributed rooftop solar is a threat not only to fossil fuel power generation, but also to the profits of monopolistic model of utilities. While the overall amount of electrical capacity represented by distributed solar power remains miniscule for now, it's quickly becoming one of leading sources of new energy deployment. As adoption grows, fossil fuel interests and utilities are succeeding in pushing anti-net metering legislation, which places surcharges on customers who deploy rooftop solar power and sell unused power back to their utility through the power grid. Other state legislation is aimed at reducing tax credits for households or businesses installing solar or allows utilities to buy back unused power at a reduced rate, while reselling it at the full retail price.

Ask Slashdot: Terminally Ill - What Wisdom Should I Pass On To My Geek Daughter?

Wed, 02/25/2015 - 12:26pm
An anonymous reader writes: I am a scientist and educator who has been enjoying and learning from Slashdot since the late 90s. Now I come to you, my geek brothers and sisters, for help. I've been diagnosed with Stage 4 pancreatic cancer, which you will remember is what took Steve Jobs and Randy Pausch from us. My condition is incurable. Palliative chemotherapy may delay the inevitable, but a realistic assessment suggests that I have anywhere from two to six months of "quality" time left, and likely not more than a year in total. I am slowly coming to terms with my imminent death, but what bothers me most is that I will be leaving my wife alone, and that my daughter will have to grow up without her father. She is in sixth grade, has an inquisitive and sharp mind, and is interested in science and music. She seems well on the path to becoming a "girl geek" like her mother, an outcome I'd welcome. Since I will not be around for all of the big events in her life, I am going to create a set of video messages for her that she can watch at those important times or just when she's having a bad day. I would like to do this before my condition progresses to the point that I am visibly ill, so time is short. In the videos I will make clear how much I treasure the time we've spent together and the wonderful qualities I see in her. What other suggestions do you have? What did you need to hear at the different stages of your life? What wisdom would have been most helpful to you? At what times did you especially need the advice of a parent? And especially for my geek sisters, how can I help her navigate the unique issues faced by girls and women in today's world? Please note that I'm posting anonymously because I don't want this to be about me. I'd prefer that the focus be on my daughter and how I can best help her. Thank you so much for your help.

Amazon Files Patent For Mobile 3D Printing Delivery Trucks

Wed, 02/25/2015 - 11:45am
ErnieKey writes: Amazon has been inching its way into the 3D printing space over the past 10 months or so. This week, however, the U.S. Patent office published a filing by Amazon for mobile 3D printing delivery trucks. The trucks would have 3D printers and CNC machines on board and be able to communicate with a central hub. When a product is ordered, the mobile 3D printing truck that's closest to the consumer's home or office would then get the order, print it, and deliver it as soon as possible.

Should a Service Robot Bring an Alcoholic a Drink?

Wed, 02/25/2015 - 11:03am
An anonymous reader writes: We've come to a point where care robots are being used to assist people with illnesses and mobility problems. They can bring medicine, a glass of water, food, and other items that a person may have trouble getting to on their own. But what limits should we set on these robots? Should they be able to deliver alcoholic beverages? If so, should they refuse to serve them to certain people, like children or alcoholics? The issue is complicated further because these robots may have been purchased by the patient, by the doctor or hospital (which sent it home with the patient to monitor their health), or by a concerned family member who wants to monitor their relative. The latest poll research by the Open Roboethics Initiative looked at people's attitudes about whether a care robot should prioritize its owner's wishes over those of the patient.

Jury Tells Apple To Pay $532.9 Million In Patent Suit

Wed, 02/25/2015 - 10:21am
An anonymous reader writes: Smartflash LLC has won a patent lawsuit against Apple over DRM and technology relating to the storage of downloaded songs, games, and videos on iTunes. Apple must now pay $532.9 million in damages. An Apple spokesperson did not hesitate to imply Smartflash is a patent troll: "Smartflash makes no products, has no employees, creates no jobs, has no U.S. presence, and is exploiting our patent system to seek royalties for technology Apple invented. We refused to pay off this company for the ideas our employees spent years innovating and unfortunately we have been left with no choice but to take this fight up through the court system." The trial happened in the same court that decided Apple owed VirnetX $368 million over FaceTime-related patents back in 2012.

Gemalto: NSA and GCHQ Probably Hacked Us, But Didn't Get SIM Encryption Keys

Wed, 02/25/2015 - 8:56am
An anonymous reader writes: Last week The Intercept published a report saying agents from the NSA and GCHQ penetrated the internal computer network of Gemalto, the world's largest maker of SIM cards. Gemalto has done an internal investigation, and surprisingly decided to post its results publicly. The findings themselves are a bit surprising, too: Gemalto says it has "reasonable grounds to believe that an operation by NSA and GCHQ probably happened." They say the two agencies were trying to intercept encryption keys that were being exchanged between mobile operators and the companies (like Gemalto) who supplied them with SIM cards. The company said it had noticed several security incidents in 2010 and 2011 that fit the descriptions in The Intercept's documents. Gemalto had no idea who was behind them until now. They add, "These intrusions only affected the outer parts of our networks – our office networks — which are in contact with the outside world. The SIM encryption keys and other customer data in general, are not stored on these networks." They claim proper use of encryption and isolation of different networks prevented attackers from getting the information they were after.

Republicans Back Down, FCC To Enforce Net Neutrality Rules

Wed, 02/25/2015 - 8:14am
An anonymous reader writes: Republican resistance has ended for the FCC's plans to regulate the internet as a public utility. FCC commissioners are working out the final details, and they're expected to approve the plan themselves on Thursday. "The F.C.C. plan would let the agency regulate Internet access as if it is a public good.... In addition, it would ban the intentional slowing of the Internet for companies that refuse to pay broadband providers. The plan would also give the F.C.C. the power to step in if unforeseen impediments are thrown up by the handful of giant companies that run many of the country's broadband and wireless networks." Dave Steer of the Mozilla Foundation said, "We've been outspent, outlobbied. We were going up against the second-biggest corporate lobby in D.C., and it looks like we've won."
