  • Tetris Is Hard To Test

    New submitter JackDW writes: Tetris is one of the best-known computer games ever made. It's easy to play but hard to master, and it's based on a NP-hard problem. But that's not all that's difficult about it. Though it's simple enough to be implemented in one line of BBC BASIC, it's complex enough to be really hard to thoroughly test.

    It may seem like you can test everything in Tetris just by playing it for a few minutes, but this is very unlikely! As I explain in this article, the game is filled with special cases that rarely occur in normal play, and these can only be easily found with the help of a coverage tool.

  • British Army Looking For Gamers For Their Smart-Tanks

    concertina226 writes The U.K. branch of global defense firm General Dynamics is working on a futuristic state-of-the-art smart-tank to replace the British Army's aging armored vehicle fleet, to be delivered to the Ministry of Defense in 2020. The Scout SV armored vehicle is the first fully-digitized armored fighting vehicle to have been built for the British Army, and is far bigger and more durable than any of its existing tanks, which are now at least 20 years old. The tank comes in six variants that can be customized with a tools for different missions, and has numerous sensors, cameras, and sights to offer real-time intelligence on weather conditions, target acquisition, and reconnaissance — all crucial battlefield data required by commanders to access and direct situations. "With the capability in the Scout SV, we're really looking for the type of people who play Xbox games – tech-savvy people who are able to take in a lot of information and process it in the proper way," says Kevin Connell, the vice president for General Dynamic UK's Land Systems Regiment.

  • Mark Zuckerberg Speaks Mandarin At Tsinghua University In Beijing

    HughPickens.com writes Abby Phillip reports at the Washington Post that that Mark Zuckerberg just posted a 30-minute Q&A at Tsinghua University in Beijing in which he answered every question exclusively in Chinese — a notoriously difficult language to learn and particularly, to speak. "It isn't just Zuckerberg's linguistic acrobatics that make this a notable moment," writes Philip. "This small gesture — although some would argue that it is a huge moment — is perhaps his strongest foray into the battle for hearts and minds in China." Zuckerberg and Facebook have been aggressively courting Chinese users for years and the potential financial upside for the business. Although Beijing has mostly banned Facebook, the company signed a contract for its first ever office in China earlier this year. A Westerner speaking Mandarin in China — at any level — tends to elicit joy from average Chinese, who seem to appreciate the effort and respect they feel learning Mandarin demonstrates. So how well did he actually do? One Mandarin speaker rates Zuckerberg's language skills at a seventh grader's speech: "It's hard not see a patronizing note in the Chinese audience's reaction to Zuckerberg's Mandarin. To borrow from Samuel Johnson's quip, he was like a dog walking on its hind legs: It wasn't done well, but it was a surprise to see it done at all."

  • Proposed Penalty For UK Hackers Who "Damage National Security": Life

    An anonymous reader writes with this excerpt from The Guardian: Government plans that mean computer users deemed to have damaged national security, the economy or the environment will face a life sentence have been criticised by experts who warn that the new law could be used to target legitimate whistleblowers. The proposed legislation would mean that any British person deemed to have carried out an unauthorised act on a computer that resulted in damage to human welfare, the environment, the economy or national security in any country would face a possible life sentence. Last week the Joint Committee on Human Rights raised concerns about the proposals and the scope of such legislation.

  • U.K. Supermarkets Beta Test Full-Body 3D Scanners For Selfie Figurines

    Lucas123 writes Walmart-owned ASDA supermarkets in the U.K. are beta testing 3D full-body scanning booths that allow patrons to buy 6-in to 9-in high "selfie" figurines. Artec Group, a maker of 3D scanners and software, said its Shapify Booth, which can scan your entire body in 12 seconds and use the resulting file to create a full-color 3D printed model, is making its U.S. debut this week. The 3D Shapify booths are equipped with four wide view, high-resolution scanners, which rotate around the person to scan every angle. Artec claims the high-powered scan and precision printing is able to capture even the smallest details, down to the wrinkles on clothes. The scanning process generates 700 captured surfaces, which are automatically stitched together to produce an electronic file ready for 3D printing. Artec offers to print the figurines for booth operators (retailers) for $50 for a 6-in model, $70 for a 7.5-in model, and $100 for a 9-in figurine.

  • Deutsche Telecom Upgrades T-Mobile 2G Encryption In US

    An anonymous reader writes T-Mobile, a major wireless carrier in the U.S. and subsidiary of German Deutsche Telecom, is hardening the encryption on its 2G cellular network in the U.S., reports the Washington Post. According to Cisco, 2G cellular calls still account for 13% of calls in the US and 68% of wireless calls worldwide. T-Mobile's upgrades will bring the encryption of older and inexpensive 2G GSM phone signals in the US up to par with that of more expensive 3G and 4G handsets. Parent company Deutsche Telecom had announced a similar upgrade of its German 2G network after last year's revelations of NSA surveillance. 2G is still important not only for that 13 percent of calls, but because lots of connected devices rely on it, or will, even while the 2G clock is ticking. The "internet of things" focuses on cheap and ubiquitous, and in the U.S. that still means 2G, but lots of things that might be connected that way are ones you'd like to be encrypted.

  • Hungary To Tax Internet Traffic

    An anonymous reader writes: The Hungarian government has announced a new tax on internet traffic: 150 HUF ($0.62 USD) per gigabyte. In Hungary, a monthly internet subscription costs around 4,000-10,000 HUF ($17-$41), so it could really put a constraint on different service providers, especially for streaming media. This kind of tax could set back the country's technological development by some 20 years — to the pre-internet age. As a side note, the Hungarian government's budget is running at a serious deficit. The internet tax is officially expected to bring in about 20 billion HUF in income, though a quick look at the BIX (Budapest Internet Exchange) and a bit of math suggests a better estimate of the income would probably be an order of magnitude higher.

  • Cell Transplant Allows Paralyzed Man To Walk

    New submitter tiberus sends word of a breakthrough medical treatment that has restored the ability to walk to a man who was paralyzed from the chest down after his spinal cord was severed in a knife attack. A research team from the UK, led by Professor Geoff Raisman, transplanted cells from the patient's nose, along with strips of nerve tissue from his ankle, to the place where the spine was severed. This allowed the fibers in the spinal cord to gradually reconnect. The treatment used olfactory ensheathing cells (OECs) - specialist cells that form part of the sense of smell. ... In the first of two operations, surgeons removed one of the patient's olfactory bulbs and grew the cells in culture. Two weeks later they transplanted the OECs into the spinal cord, which had been cut through in the knife attack apart from a thin strip of scar tissue on the right. They had just a drop of material to work with - about 500,000 cells. About 100 micro-injections of OECs were made above and below the injury. Four thin strips of nerve tissue were taken from the patient's ankle and placed across an 8mm (0.3in) gap on the left side of the cord. ... Two years after the treatment, he can now walk outside the rehabilitation center using a frame.

  • Doctor Who To Teach Kids To Code

    DCFC writes: The BBC is releasing a game to help 8- to 11-year-old kids get into coding. Based on Doctor Who, it alternates between a standard platform game and programming puzzles that introduce the ideas of sequence, loops, if..then, variables and a touch of event-driven programming. Kids will get to program a Dalek to make him more powerful. (Apparently the BBC thinks upgrading psychopathic, racist death machines is a good idea!)

  • Manga Images Depicting Children Lead to Conviction in UK

    An anonymous reader writes with this news from the UK, as reported by Ars Technica: A 39-year-old UK man has been convicted of possessing illegal cartoon drawings of young girls exposing themselves in school uniforms and engaging in sex acts. The case is believed to be the UK's first prosecution of illegal manga and anime images. Local media said that Robul Hoque was sentenced last week to nine months' imprisonment, though the sentence is suspended so long as the defendant does not break the law again. Police seized Hoque's computer in 2012 and said they found nearly 400 such images on it, none of which depicted real people but were illegal nonetheless because of their similarity to child pornography. Hoque was initially charged with 20 counts of illegal possession but eventually pled guilty to just 10 counts.

  • Google Changes 'To Fight Piracy' By Highlighting Legal Sites

    mrspoonsi writes Google has announced changes to its search engine in an attempt to curb online piracy. The company has long been criticised for enabling people to find sites to download entertainment illegally. The entertainment industry has argued that illegal sites should be "demoted" in search results. The new measures, mostly welcomed by music trade group the BPI, will instead point users towards legal alternatives such as Spotify and Google Play. Google will now list these legal services in a box at the top of the search results, as well as in a box on the right-hand side of the page. Crucially, however, these will be adverts — meaning if legal sites want to appear there, they will need to pay Google for the placement.

  • In UK, Internet Trolls Could Face Two Years In Jail

    An anonymous reader writes with this news from The Guardian about a proposed change in UK law that would greatly increase the penalties for online incivility: Internet trolls who spread "venom" on social media could be jailed for up to two years, the justice secretary Chris Grayling has said as he announced plans to quadruple the maximum prison sentence. Grayling, who spoke of a "baying cybermob", said the changes will allow magistrates to pass on the most serious cases to crown courts. The changes, which will be introduced as amendments to the criminal justice and courts bill, will mean the maximum custodial sentence of six months will be increased to 24 months. Grayling told the Mail on Sunday: "These internet trolls are cowards who are poisoning our national life. No one would permit such venom in person, so there should be no place for it on social media. That is why we are determined to quadruple the six-month sentence.

  • Brain Patterns Give Clues To Why Some People Just Keep Gambling

    Research from several UK universities, as reported by Time, indicates that the brain activity of compulsive gamblers shows a marked difference in response to pleasure-triggering behavior, which may help explain why they have trouble stopping: [The participants] took an amphetamine capsule, which unleashes endorphins with similar effects to the rush you get from exercise or alcohol, the study says. An additional PET scan revealed that pathological gamblers responded differently to the drug. They released fewer endorphins than those who didn't gamble, and they also reported lower levels of euphoria on a questionnaire afterward. This might help explain the addictive part of pathological gambling: to get pleasure from the act, problem gamblers might need more of it or to work harder for it.

  • BBC Takes a Stand For the Public's Right To Remember Redacted Links

    Martin Spamer writes with word that the BBC is to publish a continually updated list of its articles removed from Google under the controversial 'right to be forgotten' notices." The BBC will begin - in the "next few weeks" - publishing the list of removed URLs it has been notified about by Google. [Editorial policy head David] Jordan said the BBC had so far been notified of 46 links to articles that had been removed. They included a link to a blog post by Economics Editor Robert Peston. The request was believed to have been made by a person who had left a comment underneath the article. An EU spokesman later said the removal was "not a good judgement" by Google.

  • South Korean ID System To Be Rebuilt From Scratch After Massive Leaks

    AmiMoJo writes: South Korea's national identity card system may need a complete overhaul following huge data thefts dating back to 2004. The government is considering issuing new ID numbers to every citizen over age 17, costing billions of dollars. The ID numbers and personal details of an estimated 80% of the country's 50 million people have been stolen from banks and other targets. Some 20 million people, including President Park Geun-hye, have been victims of a data theft. Citizens are unable to change their credentials, which are used in many different sectors, making them an attractive target for hackers.

  • Adobe: Click-to-Play Would Have Avoided Flood of Java Zero-days

    mask.of.sanity writes: Oracle could have saved mountains of cash and bad press if Click-to-Play was enabled before Java was hosed by an armada of zero day vulnerabilities, Adobe security boss Brad Arkin says. The simple fix introduced into browsers over the last year stopped the then zero day blitzkrieg in its tracks by forcing users to click a button to enable Java.

  • Samsung Achieves Outdoor 5G Mobile Broadband Speed of 7.5Gbps

    Mark.JUK writes: Samsung has become the first to successfully demonstrate a future 5G mobile network running at speeds of 7.5Gbps in a stationary outdoor environment. They also managed 1.2Gbps while using the same technology and driving around a 4.3km-long race track at speeds of up to 110kph.

    Crucially, the test was run using the 28GHz radio spectrum band, which ordinarily wouldn't be much good for mobile networks where wide coverage and wall penetration is an important requirement. But Samsung claims it can mitigate at least some of that by harnessing the latest Hybrid Adaptive Array Technology (HAAT), which uses millimeter wave frequency bands to enable the use of higher frequencies over greater distances. Several companies are competing to develop the first 5G technologies, although consumers aren't expected to see related services until 2020 at the earliest.

  • How Nigeria Stopped Ebola

    HughPickens.com writes Pamela Engel writes that Americans need only look to Nigeria to calm their fears about an Ebola outbreak in the US. Nigeria is much closer to the West Africa outbreak than the US is, yet even after Ebola entered the country in the most terrifying way possible — via a visibly sick passenger on a commercial flight — officials successfully shut down the disease and prevented widespread transmission. If there are still no new cases on October 20, the World Health Organization will officially declare the country "Ebola-free." Here's how Nigeria did it.

    The first person to bring Ebola to Nigeria was Patrick Sawyer, who left a hospital in Liberia against the wishes of the medical staff and flew to Nigeria. Once Sawyer arrived, it became obvious that he was ill when he passed out in the Lagos airport, and he was taken to a hospital in the densely packed city of 20 million. Once the country's first Ebola case was confirmed, Port Health Services in Nigeria started a process called contact tracing to limit the spread of the disease and created an emergency operations center to coordinate and oversee the national response. Health officials used a variety of resources, including phone records and flight manifests, to track down nearly 900 people who might have been exposed to the virus via Sawyer or the people he infected. As soon as people developed symptoms suggestive of Ebola, they were isolated in Ebola treatment facilities. Without waiting to see whether a "suspected" case tested positive, Nigeria's contact tracing team tracked down everyone who had had contact with that patient since the onset of symptoms making a staggering 18,500 face-to-face visits.

    The US has many of these same procedures in place for containing Ebola, making the risk of an outbreak here very low. Contact tracing is exactly what is happening in Dallas right now; if any one of Thomas Eric Duncan's contacts shows symptoms, that person will be immediately isolated and tested. "That experience shows us that even in the case in Nigeria, when we found out later in the timeline that this patient had Ebola, that Nigeria was able to identify contacts, institute strict infection control procedures and basically bring their outbreak to a close," says Dr. Tom Inglesby. "They did a good job in and of themselves. They worked closely with the U.S. CDC. If we can succeed in Nigeria I do believe we will stop it here."

  • How an FBI Informant Led the Hack of British Tabloid "The Sun"

    Daniel_Stuckey writes Hector Xavier Monsegur, also known online as "Sabu," was caught by the FBI in June of 2011 for a litany of hacking-related offenses and, within hours, began cooperating with authorities in hopes of receiving a lenient sentence. Now, never-before-published FBI records and exclusive interviews detail how the informant rallied other hackers to attack various News Corp. interests, including The Sun, at a time that the FBI has said it was tracking all of Monsegur's online activity. And for a week shortly after his arrest, he was privy to the anti-Murdoch campaign waged by Anonymous, according to the documents obtained by Motherboard.

  • Pentagon Reportedly Hushed Up Chemical Weapons Finds In Iraq

    mr_mischief writes "Multiple sources report that the US found remnants of WMD programs, namely chemical weapons, in Iraq after all. Many US soldiers were injured by them, in fact. The Times reports: "From 2004 to 2011, American and American-trained Iraqi troops repeatedly encountered, and on at least six occasions were wounded by, chemical weapons remaining from years earlier in Saddam Hussein's rule. In all, American troops secretly reported finding roughly 5,000 chemical warheads, shells or aviation bombs, according to interviews with dozens of participants, Iraqi and American officials, and heavily redacted intelligence documents obtained under the Freedom of Information Act."
