MIT Scientists Develop New Wi-Fi That's 330% Faster

Slashdot - Wed, 08/24/2016 - 23:05
An anonymous reader quotes a report from MSN: Scientists at MIT claim to have created a new wireless technology that can triple Wi-Fi data speeds while also doubling the range of the signal. Dubbed MegaMIMO 2.0, the system will shortly enter commercialization and could ease the strain on our increasingly crowded wireless networks. Multiple-input-multiple-output technology, or MIMO, helps networked devices perform better by combining multiple transmitters and receivers that work simultaneously, allowing then to send and receive more than one data signal at the same time. MIT's MegaMIMO 2.0 works by allowing several routers to work in harmony, transmitting data over the same piece of spectrum. MIT claimed that during tests, MegaMIMO 2.0 was able to increase data transfer speed of four laptops connected to the same Wi-Fi network by 330 percent. Paper co-author Rahul said the technology could also be applied to mobile phone networks to solve similar congestion issues. "In today's wireless world, you can't solve spectrum crunch by throwing more transmitters at the problem, because they will all still be interfering with one another," Ezzeldin Hamed, lead author on a paper on the topic, told MIT News. "The answer is to have all those access points work with each other simultaneously to efficiently use the available spectrum."

Bill Nye Explains That the Flooding In Louisiana Is the Result of Climate Change

Slashdot - Wed, 08/24/2016 - 22:27
Reader mspohr writes: Our favorite science guy has an interview (and video) in Quartz where he explains how Louisiana flooding is due to climate change:"As the ocean gets warmer, which it is getting, it expands," Nye explained. "Molecules spread apart, and then as the sea surface is warmer, more water evaporates, and so it's very reasonable that these storms are connected to these big effects."The article also notes that a National Academy of Sciences issued a report with the same findings: "Scientists from around the world have concurred with Nye that this is exactly what the effects of climate change look like, and that disasters like the Louisiana floods are going to happen more and more. According to a National Academy of Sciences report published earlier this year, extreme flooding can be traced directly to human-induced global warming. As the atmosphere warms, it retains more moisture, leading to bouts of sustained, heavy precipitation that can cause floods."

Apple Under Tim Cook: More Socially Responsible, Less Visionary

Slashdot - Wed, 08/24/2016 - 21:45
Let's talk about Apple, unarguably one of the most remarkable companies on the face of the earth. (Remarkable doesn't necessarily mean great -- it just means that the company is something worth making a remark). You can like it, or hate it, but you can simply not ignore Apple. But what's the occasion, you ask? It's been five years since Tim Cook took over as Apple CEO. (Editor's note: auto-playing video ahead, which may annoy you) Under his leadership, Apple has grown to become the world's most successful company, doubling the stock price and registering a staggering 84 percent growth in its net worth. Media outlets are abuzz with articles, analysis, and over-analysis of Tim Cook's Apple today. Some excerpts from a CNN article: Apple's culture has changed noticeably, both for the better and the worse. [...] If Jobs put a dent in the universe through Apple's coveted products, Cook is making his mark by highlighting the importance of social efforts: LGBT rights, philanthropy, corporate diversity, renewable energy and improving manufacturing conditions abroad. Under Cook's leadership, Apple finally began matching charitable contributions from employees, which had long been a sore spot for staff. Apple had 110,000 full-time employees as of the end of September 2015, nearly doubling from the 60,400 employees it reported having in September 2011, shortly after Cook took over, according to annual filings with the SEC. [...] There's now a feeling among some Apple insiders that the company is just running the same product playbook that Jobs created in his final years at the helm. "For four or five years, the playbook is the same that's been done," says Amit Sharma, a former Apple exec on the online store team. But, he adds, "just because everybody is looking for new doesn't mean it's not working."

Earth-Like Planet, With Ambitious Life Possibility, Found Orbiting the Star Next Door

Slashdot - Wed, 08/24/2016 - 21:00
There's another Earth out there. For real, this time. Astronomers announced on Wednesday that they had detected a planet orbiting Proxima Centauri, the closest neighbor to our solar system. Intriguingly, the planet is in the star's "Goldilocks zone," they said, a place that hints that it may not be too hot nor too cold. Which in turn means that liquid water could exist at the surface, and by extension, it raises the possibility of life. Nature reports:"The search for life starts now," says Guillem Anglada-Escude, an astronomer at Queen Mary University of London and leader of the team that made the discovery. Humanity's first chance to explore this nearby world may come from the recently announced Breakthrough Starshot initiative, which plans to build fleets of tiny laser-propelled interstellar probes in the coming decades. Travelling at 20% of the speed of light, they would take about 20 years to cover the 1.3 parsecs from Earth to Proxima Centauri. Proxima's planet is at least 1.3 times the mass of Earth. The planet orbits its red-dwarf star -- much smaller and dimmer than the Sun -- every 11.2 days. "If you tried to pick the type of planet you'd most want around the type of star you'd most want, it would be this," says David Kipping, an astronomer at Columbia University in New York City. "It's thrilling."Much about the planet is still unknown. Astronomers have some ideas about its size and distance from its parent star. Scientists say they are working off computer models that offer mere hints of what's possible. Also, there's no picture available for this planet as of yet.

The US Army Has Too Many Video Games

Slashdot - Wed, 08/24/2016 - 20:12
An anonymous reader shares a Motherboard report:The US Army sees itself in a transitional period. Unlike a decade ago, soldiers are training less today on how to conduct "stability" operations for a counter-insurgency campaign, and more on what the Army does best: fighting other armies. But training is expensive and requires time and a lot of space. Training a gunner for an M-1 Abrams tank means reserving time on a limited number of ranges and expending real ammunition. So to lower costs and make training more efficient -- in theory -- the Army has adopted a variety of games to simulate war. There's just a few problems. Some of the Army's virtual simulators sit collecting dust, and one of them is more expensive and less effective than live training. At one base, soldiers preferred to play mouse-and-keyboard games over a more "realistic" virtual room. Then again, the Army has cooler games than you do. M-1 tank gunners, for example, can train inside a full-scale, computerized mock-up of their station called the Advanced Gunnery Training System, which comes inside a large transportable container. Instead of looking through real sights down a range, the soldier squints through a replica and sees a virtual simulacrum of, say, an enemy tank. Push a button and the "cannon" fires. The Army fields similar systems for the Stryker, a wheeled armored troop transport that fits an optional 105-millimeter gun. Soldiers train inside another simulated gunnery station for the M-2 Bradley fighting vehicle. Another system, Common Driver, simulates a variety of military vehicles.

Cloudflare Faces Lawsuit For Assisting Pirate Sites

Slashdot - Wed, 08/24/2016 - 19:20
An anonymous reader shares a TorrentFreak report: In recent months CloudFlare has been called out repeatedly for offering its services to known pirate sites, including The Pirate Bay. These allegations have now resulted in the first lawsuit after adult entertainment publisher ALS Scan filed a complaint against CloudFlare at a California federal court. [...] Copyright holders are not happy with CloudFlare's actions. Just recently, the Hollywood-affiliated group Digital Citizens Alliance called the company out for helping pirate sites to stay online. Adult entertainment outfit ALS Scan agrees and has now become the first dissenter to take CloudFlare to court. In a complaint filed at a California federal court, ALS describes piracy as the greatest threat to its business. The rise of online piracy has significantly hurt the company's profits, they argue, noting that "pirate" sites are not the only problem. "The problems faced by ALS are not limited to the growing presence of sites featuring infringing content, or 'pirate' sites. A growing number of service providers are helping pirate sites thrive by supporting and engaging in commerce with these sites," ALS writes.

Over 25 Million Accounts Stolen After Mail.ru Forums Hacked

Slashdot - Wed, 08/24/2016 - 18:40
An anonymous reader writes: Over 25 million accounts associated with forums hosted by Russian internet giant Mail.ru have been stolen by hackers. Two hackers carried out attacks on three separate game-related forums in July and August. One forum alone accounted for almost half of the breached data -- a little under 13 million records; the other two forums making up over 12 million records. The databases were stolen in early August, according to breach notification site LeakedSource.com, which obtained a copy of the databases. The hackers' names aren't known, but used known SQL injection vulnerabilities found in older vBulletin forum software to get access to the databases. An analysis of the breached data showed that hackers took 12.8 million accounts from cfire.mail.ru; a total of 8.9 million records from parapa.mail.ru, and 3.2 million accounts from tanks.mail.ru. The hackers were able to obtain usernames, email addresses, scrambled passwords, and birthdays.

NASA's Outsourced Computer People Are Even Worse Than You Might Expect

Slashdot - Wed, 08/24/2016 - 18:00
Eric berger, writing for ArsTechnica: As part of a plan to help NASA "modernize" its desktop and laptop computers, the space agency signed a $2.5 billion services contract with HP Enterprise Services in 2011. According to HP (now HPE), part of the Agency Consolidated End-User Service (ACES) program the computing company would "modernize NASA's entire end-user infrastructure by delivering a full range of personal computing services and devices to more than 60,000 users." HPE also said the program would "allow (NASA) employees to more easily collaborate in a secure computing environment." The services contract, alas, hasn't gone quite as well as one might have hoped. This week Federal News Radio reported that HPE is doing such a poor job that NASA's chief information officer, Renee Wynn, could no longer accept the security risks associated with the contract. Wynn, therefore, did not sign off on the authority to operate (ATO) for systems and tools.A spokesperson for NASA said: "NASA continues to work with HPE to remediate vulnerabilities. As required by NASA policy, system owners must accomplish this remediation within a specified period of time. For those vulnerabilities that cannot be fully remediated within the established time frame, a Plan of Actions and Milestones (POAM) must be developed, approved, and tracked to closure."

Singapore To Cut Off Public Servants From the Internet

Slashdot - Wed, 08/24/2016 - 17:20
Singapore is planning to cut off web access for public servants as a defence against potential cyber attack, Reuters reports. The local government's move has already been criticized by many, who say that it marks a retreat for a technologically advanced city-state that has trademarked the term "smart nation". From an article on The Guardian: Some security experts say the policy, due to be in place by May, risks damaging productivity among civil servants and those working at more than four dozen statutory boards, and cutting them off from the people they serve. It may only raise slightly the defensive walls against cyber attack, they say. Ben Desjardins, director of security solutions at network security firm Radware, called it "one of the more extreme measures I can recall by a large public organisation to combat cyber security risks." Stephen Dane, a Hong Kong-based managing director at networking company Cisco Systems, said it was "a most unusual situation" and Ramki Thurimella, chair of the computer science department at the University of Denver, called it both "unprecedented" and "a little excessive".

A Design Defect Is Plaguing Many iPhone 6 and 6 Plus Units

Slashdot - Wed, 08/24/2016 - 16:40
Evan Selleck, writing for iPhoneHacks (edited and condensed): For many iPhone 6 and iPhone 6 Plus owners out there in the wild, a design defect is apparently causing some huge issues. Gadget repair firm iFixit has reported about a flaw dubbed "Touch Disease", which it claims is cropping up. With it, owners of the phones are experiencing, to start, a gray bar that appears at the very top of their display. And, for many others, the display itself becomes unresponsive to touch, or less responsive overall. In the blog post, iFixit says the problem stems from issues with the touchscreen controller chip, which is soldered onto the logic board. Interestingly enough, iFixit posits that the same internal design decisions that led to "Endgate" might be causing the issue leading to Touch Disease, too: "In both the iPhone 6 and 6 Plus, the Touch IC chips connect to the logic board via an array of itty-bitty solder balls -- "like a plate resting on marbles," Jessa explains. Over time, as the phone flexes or twists slightly during normal use, those solder balls crack and start to lose contact with the board. "At first, there may be no defect at all. Later you might notice that the screen is sometimes unresponsive, but it is quick to come back with a hard reset," Jessa explains. "As the crack deepens into a full separation of the chip-board bond, the periods of no touch function become more frequent."

Opera Brings Its Free VPN Service To Android

Slashdot - Wed, 08/24/2016 - 16:00
Frederic Lardinois, writing for TechCrunch: Earlier this year, Opera launched its free and unlimited VPN service for iOS; today it is bringing the same functionality to Android. Like the iOS version, the Android app is based on Opera's acquisition of SurfEasy in 2015 and allows you to surf safely when you are on a public network. While Opera's marketing mostly focuses on safety, Opera VPN also allows you to appear as if you are in the U.S., Canada, Germany, Singapore and The Netherlands, so it's also a way to route around certain geo-restrictions without having to opt for a paid service. In addition to its VPN features, the service also allows you to block ad trackers. Somewhat ironically, though, the app itself will show you some pretty unintrusive ads. "The Opera VPN app for Android sets itself apart from other VPNs by offering a completely free service without a data limit, no logÂin required, advanced WiÂFi protection features and no need for a subscription," says Chris Houston, the president of Opera's SurfEasy VPN division, in today's announcement.

Facebook Is Testing Autoplaying Video With Sound

Slashdot - Wed, 08/24/2016 - 15:00
An anonymous reader writes: Facebook is testing a "feature" that autoplays video clips on your feed with sound. It's not a very big test, but there's a possibility the company could roll it out to a larger group of users. The Next Web reports: "The company is currently trying two methods of getting people to watch video with sound in Australia: the aforementioned autoplaying, and an unmute button on the lower right corner of videos, like Vine videos on a desktop. The latter certainly sounds more reasonable; the last thing you want is to be checking Facebook quickly during a meeting or class, and suddenly have your phone blaring out an advert because you happened to stop on a video. Thankfully, you can disable the 'feature' from your settings, but the point is there's nothing wrong with the current opt-in approach, especially considering how many companies are embracing video captioning, and that Facebook even has its own auto-caption tool for advertisers." "We're running a small test in News Feed where people can choose whether they want to watch videos with sound on from the start," a Facebook spokesperson told Mashable Australia. "For people in this test who do not want sound to play, they can switch it off in Settings or directly on the video itself. This is one of several tests we're running as we work to improve the video experience for people on Facebook."

Representative Line: Accuracy in Comments

The Daily WTF - Wed, 08/24/2016 - 12:30

Comments are rough. I always take the stance that code should always be clear enough to explain what it does, but you’ll may need a comment to explain why it does that. I recently attended a talk by Sean Griffin (maintainer of Rails) who argued that commit messages should accomplish that goal, since they can contain far more content than a code comment, and while code comments and code can drift apart and cease to be accurate, commit messages are always linked to the point-in-time when they were made. Donald Knuth, on the other hand, might argue that code should annotate comments instead of the opposite.

Regardless of the method we use, I think most of us would agree that code needs some documentation in the same way it needs tests: it should exist, but we don’t want to have to create it.

Stephania found herself in the situation where she was creating the documentation. In this case, I don’t think we have to worry about the comment ceasing to be an accurate description of the code. This comment doesn’t need to be linked to a specific point in time- it tells us everything we need to know about the entire codebase.

Microsoft Buys AI-Powered Scheduling App Genee

Slashdot - Wed, 08/24/2016 - 12:00
An anonymous reader quotes a report from The Stack: Microsoft has announced that it has completed its acquisition of artificial intelligence-based scheduling app Genee for an undisclosed amount. The app, which was launched in beta last year, uses natural language processing tools and decision-making algorithms to allow users to schedule appointments without having to consult a calendar. Prior to the acquisition, Genee supported scheduling across Facebook, Twitter, Skype, email, and via SMS. From September 1, Genee will close its own service and will officially join Microsoft, supposedly the Office 365 team. Microsoft believes the addition will help it "further [its] ambition to bring intelligence into every digital experience."

NASA Reconnects With 'Lost' STEREO-B Satellite

Slashdot - Wed, 08/24/2016 - 09:00
NASA lost contact with its STEREO-B spacecraft twenty-two months ago during a routine 72-hour test. On Sunday, the spacecraft reconnected with NASA roughly 189 million miles away from Earth. While that would seem like a cause for celebration, "the very hard and scary work is just the beginning, says Stereo project scientist Joe Gurman, as the agency has to turn on the computer to learn more about the current state of the spacecraft -- a process that may make the craft lose contact with them again. Slashdot user bongey writes: NASA may have only two minutes or less to fix a STEREO-B satellite before the computer causes it to lose contact again. NASA lost contact with their STEREO-B satellite nearly twenty-two months ago when performing a routine test. NASA scientists are afraid to turn on the computer at this point because it may cause them to lose contact again. A more detailed technical summary can be found here. "We have something like two minutes between when STEREO-B receives the command to boot up one of its computers and when it starts doing what we don't want it to do," Gurman said. Business Insider writes, "Making matters worse, it takes about 20 seconds to send commands to the spacecraft -- a data rate that makes a dial-up modem seem lightning fast."

20% of Scientific Papers On Genes Contain Conversion Errors Caused By Excel, Says Report

Slashdot - Wed, 08/24/2016 - 05:30
An anonymous reader writes from a report via WinBeta: A new report from scientists Mark Ziemann, Yotam Eren, and Assam El-Osta says that 20% of scientific papers on genes contain gene name conversion errors caused by Excel. In the scientific article, titled "Gene name errors are widespread in the scientific literature," article's abstract section, the scientists explain: "The spreadsheet software Microsoft Excel, when used with default settings, is known to convert gene names to dates and floating-point numbers. A programmatic scan of leading genomics journals reveals that approximately one-fifth of papers with supplementary Excel gene lists contain erroneous gene name conversions." It's easy to see why Excel might have problems with certain gene names when you see the "gene symbols" that the scientists use as examples: "For example, gene symbols such as SEPT2 (Septin 2) and MARCH1 [Membrane-Associated Ring Finger (C3HC4) 1, E3 Ubiquitin Protein Ligase] are converted by default to '2-Sep' and '1-Mar', respectively. Furthermore, RIKEN identifiers were described to be automatically converted to floating point numbers (i.e. from accession '2310009E13' to '2.31E+13'). Since that report, we have uncovered further instances where gene symbols were converted to dates in supplementary data of recently published papers (e.g. 'SEPT2' converted to '2006/09/02'). This suggests that gene name errors continue to be a problem in supplementary files accompanying articles. Inadvertent gene symbol conversion is problematic because these supplementary files are an important resource in the genomics community that are frequently reused. Our aim here is to raise awareness of the problem." You can view the scientific paper in its entirety here.

Microsoft Details Its 24-Core 'Holographic Processor' Used In HoloLens

Slashdot - Wed, 08/24/2016 - 03:45
The processor powering Microsoft's HoloLens augmented reality headset has been a mystery -- until now. During the annual Hot Chips conference in Cupertino, California, Microsoft revealed some juicy details about the secretive chip. PCWorld reports: "The HoloLens' HPU is a custom 28nm coprocessor designed by TSMC, The Register reports. The chip packs 24 Tensilica digital signal processor (DSP) cores. As opposed to more general-purpose CPU cores, DSPs are a specialized technology designed for rapidly processing data flowing in from the world -- a no doubt invaluable asset while rendering augmented reality environments in real time. Microsoft's HPU also contains roughly 65 million logic gates, 8MB of SDRAM, and 1GB of traditional DDR3 RAM. It draws less than 10W of power, and features PCIe and standard serial interfaces. The HPU's dedicated hardware is up to 200 times faster than performing the same calculations via software on the less-specialized 14nm Intel Cherry Trail CPU. Microsoft added custom instructions to the DSP cores that allow the HPU to churn through HoloLens-specific tasks even faster, The Register reports. The HPU can perform roughly 1 trillion calculations per second, and the data it passes to the CPU requires little additional processing."

Pinterest Acquires Instapaper

Slashdot - Wed, 08/24/2016 - 03:15
An anonymous reader quotes a report from The Verge: Instapaper, a pioneering app for saving articles to read later, has been acquired -- again. The app, which was created by developer Marco Arment and sold to Betaworks in 2013, has found a new home at Pinterest. The goal is "to accelerate discovering and saving articles on Pinterest," the company said in a statement. It will continue to operate as a standalone app, and the Instapaper team will work on both that app and on Pinterest generally. Terms of the deal were not disclosed. As a visual search engine, Pinterest isn't often thought of as a place to bookmark written content. But in 2013 the company introduced article pins, a format that creates rich bookmarks complete with a photo and a preview of the text. The acquisition of Instapaper suggests the company believes there is more to be done there -- although it's not certain how valuable that will be for Pinterest. Instapaper can be used for free or in a $30-a-year premium version; the company has never said how many subscribers it has.

Sony Tries To Remove News Articles About PlayStation 4 Slim Leak From The Internet

Slashdot - Wed, 08/24/2016 - 02:45
Sony is expected to announce two new PlayStation 4 consoles at a scheduled event on September 7th in New York City, but as that date nears more leaks of the consoles have emerged. The most recent leak appears to show the upcoming PlayStation 4 Slim, which Sony is trying to remove from the internet by taking down news articles from social media accounts about the leak. Erik Kain via @erikkain on Twitter tweeted (Tweet no longer exists): "Sony issued a takedown and had this post removed from my Facebook page: https://t.co/fIjP0buTdY (Warning: may be paywalled)." Techdirt reports: "[The Forbes post] references the work Eurogamer did in visiting the leaker of the image to confirm the console is for real (it is), as well as generating its own image and even video of the console working for its story on the leak. But if you go today to the Eurogamer post about the leak, the video has been replaced by the following update. UPDATE, 7.30pm: Upon taking legal advice, we have removed the video previously referenced in this article. Left unsaid is whether or not any contact had been made by Sony with Eurogamer, thus prompting this 'legal advice,' but one can imagine that being the case, particularly given Sony's threats to social media users sharing images and reporting of Sony leaks and, more to the point, threats against any media that might report on those leaks."

US Trade Judge Clears Fitbit of Stealing Jawbone's Trade Secrets

Slashdot - Wed, 08/24/2016 - 02:05
An anonymous reader quotes a report from Reuters: Fitbit did not steal rival Jawbone's trade secrets, a U.S. International Trade Commission judge ruled on Tuesday, dashing Jawbone's hopes of securing an import ban against Fitbit's wearable fitness tracking devices. The judge, Dee Lord, said that there had been no violation of the Tariff Act, which gives the commission the power to block products that infringe U.S. intellectual property, because "no party has been shown to have misappropriated any trade secret." The ruling means Jawbone comes away with nothing from a complaint it filed with the trade agency in July 2015, accusing Fitbit of infringing six patents and poaching employees who took with them confidential data about Jawbone's business, such as plans, supply chains and technical details. Jawbone first sued Fitbit last year over trade secret violations in California state court, where the case is still pending. The companies, both based in San Francisco, are also litigating over patents in federal court.
