Engineers Explain Why the Galaxy Note 7 Caught Fire (digitaltrends.com)

Engineers with manufacturing technology company Instrumental tore apart a Galaxy Note 7 to try and figure out what may have caused some devices to overheat and explode, causing Samsung to recall and eventually cancel all Galaxy Note 7 devices. In their damning new report, the engineers discovered the root of the problem appears to be that the battery is too tightly packed inside the body of the Note 7. Digital Trends reports: They discovered the battery was so tightly packed inside the Galaxy Note 7's body that any pressure from battery expansion, or stress on the body itself, may squeeze together layers inside the battery that are never supposed to touch -- with explosive results. Batteries swell up under normal use, and we place stress on a phone's body by putting it our pocket and sitting down, or if it's dropped. Tolerances for battery expansion are built into a smartphone during design, and Instrumental notes Samsung used "a super-aggressive manufacturing process to maximize capacity." In other words, the Galaxy Note 7 was designed to be as thin and sleek as possible, while containing the maximum battery capacity for long use, thereby better competing against rival devices such as the iPhone 7 Plus and improving on previous Note models. The report speculates that any pressure placed on the battery in its confined space may have squeezed together positive and negative layers inside the cell itself, which were thinner than usual in the Note 7's battery already, causing them to touch, heat up, and eventually in some cases, catch fire. Delving deeper into the design, the engineers say the space above a battery inside a device needs a "ceiling" that equates to approximately 10 percent of the overall thickness. The Galaxy Note 7 should have had a 0.5mm ceiling; it had none.

Millions In US Still Living Life In Internet Slow Lane (arstechnica.com) 26

An anonymous reader quotes a report from Ars Technica: Millions of Americans still have extremely slow Internet speeds, a new Federal Communications Commission report shows. While the FCC defines broadband as download speeds of 25Mbps, about 47.5 million home or business Internet connections provided speeds below that threshold. Out of 102.2 million residential and business Internet connections, 22.4 million offered download speeds less than 10Mbps, with 5.8 million of those offering less than 3Mbps. About 25.1 million connections offered at least 10Mbps but less than 25Mbps. 54.7 million households had speeds of at least 25Mbps, with 15.4 million of those at 100Mbps or higher. These are the advertised speeds, not the actual speeds consumers receive. Some customers will end up with slower speeds than what they pay for. Upload speeds are poor for many Americans as well. While the FCC uses 3Mbps as the upload broadband standard, 16 million households had packages with upload speeds less than 1Mbps. Another 27.2 million connections were between 1Mbps and 3Mbps, 30.1 million connections were between 3Mbps and 6Mbps, while 29 million were at least 6Mbps. The Internet Access Services report released last week contains data as of December 31, 2015. The 11-month gap is typical for these reports, which are based on information collected from Internet service providers. The latest data is nearly a year old, so things might look a bit better now, just as the December 2015 numbers are a little better than previous ones.

Dailymotion Hack Exposes Millions of Accounts (zdnet.com) 7

Millions of accounts associated with video sharing site Dailymotion, one of the biggest video platforms in the world, have been stolen. From a ZDNet report: A hacker extracted 85.2 million unique email addresses and usernames from the company's systems, but about one-in-five accounts -- roughly 18.3 million-- had associated passwords, which were scrambled with the bcrypt hashing function, making the passwords difficult to crack. The hack is believed to have been carried out on October 20 by a hacker, whose identity isn't known, according to LeakedSource, a breach notification service, which obtained the data. Dailymotion launched in 2005, and is currently the 113rd most visited website in the world, according to Alexa rankings.

Interns At Tech Companies Are Better Paid Than Most American Workers (qz.com) 96

According to a survey conducted by Jesse Collins, a senior at Purdue University and former Yelp intern, interns at tech companies make much more money on an annualized basis than workers in the vast majority of other occupations. From a report on Quartz: About 300 of the nearly 600 people who responded to the survey said they had received internship offers from big companies like Facebook, Twitter, Yelp, and Goldman Sachs for 2017. On average, the internship recipients said they would be paid $6,500 per month, the equivalent of $78,000 per year (the survey is still open, so results may change). Many also said they would receive more than $1,000 worth of stipends per month for housing and travel or signing bonuses. Internships typically run for a summer, but we've annualized the numbers. If the average intern who responded to Collins' survey were to work for a year, he would make $30,000 more than the average annual income for all occupations in the U.S., which is $48,000. Of the 1,088 occupation categories within which the Bureau of Labor Statistics tracks average income, workers in only about 200 of them on average make more money in a year than the intern would.

Many CEOs Believe Technology Will Make People Largely Irrelevant (betanews.com) 224

An anonymous reader shares a report on BetaNews:Although artificial intelligence (AI), robotics and other emerging technologies may reshape the world as we know it, a new global study has revealed that the many CEOs now value technology over people when it comes to the future of their businesses. The study was conducted by the Los Angeles-based management consultant firm Korn Ferry that interviewed 800 business leaders across a variety of multi-million and multi-billion dollar global organizations. The firm says that 44 percent of the CEOs surveyed agreed that robotics, automation and AI would reshape the future of many work places by making people "largely irrelevant." The global managing director of solutions at Korn Ferry Jean-Marc Laouchez explains why many CEOs have adopted this controversial mindset, saying: "Leaders may be facing what experts call a tangibility bias. Facing uncertainty, they are putting priority in their thinking, planning and execution on the tangible -- what they can see, touch and measure, such as technology instruments."

Most DVR Owners Are Recording Live Sports, Survey Says (cnet.com) 87

A new survey by Thuurz Sports, a company that works with TV providers to increase the size of sports viewing audiences, finds that 84.1 percent of DVR owners record live sports, many of them as a "backup" for when they might miss the end (or the beginning) or the game, and a majority (58 percent) to skip the ads. From a report on CNET: "Over the past decade, DVR viewing has undermined certain elements of the TV business. Reacting to this threat, sports TV executives have rightly focused on the genre's relative strength, calling sports programming 'DVR-proof'," says Brian Ring, the consultant who created the survey for Thuuz, in the press release. "Sports are best viewed live, but this survey highlights the fact that most fans with DVRs regularly use. Most TV shows and movies these days are available on-demand from various sources, but live events, particularly sports, are considered among the most "DVR-proof" since there's more value in seeing the result live.

Apple Says It Is Working On Self-Driving Cars (theguardian.com) 91

For the first time, Apple has said that it is indeed working on technology to develop self-driving cars. The company confirmed late last week its previously secret initiative in a statement to the U.S. highway regulator. From a report on The Guardian: "The company is investing heavily in the study of machine learning and automation, and is excited about the potential of automated systems in many areas, including transportation," said the letter from Steve Kenner, Apple's director of product integrity, to the head of the National Highway Traffic Safety Administration (NHTSA). The letter offered no details of the project, instead highlighting the "significant societal benefits of automated vehicles," which it described as a life-saving technology, potentially preventing millions of car crashes and thousands of fatalities each year.In a statement to Financial Times (might be paywalled), a spokesperson for Apple said, "We've provided comments to NHTSA because Apple is investing heavily in machine learning and autonomous systems. There are many potential applications for these technologies, including the future of transportation, so we want to work with NHTSA to help define the best practices for the industry."

Google's DeepMind is Opening Up Its Flagship Platform To AI Researchers Outside the Company (businessinsider.com) 18

Artificial intelligence (AI) researchers around the world will soon be able to use DeepMind's "flagship" platform to develop innovative computer systems that can learn and think for themselves. From a report on BusinessInsider: DeepMind, which was acquired by Google for $400 million in 2014, announced on Monday that it is open-sourcing its "Lab" from this week onwards so that others can try and make advances in the notoriously complex field of AI. The company says that the DeepMind Lab, which it has been using internally for some time, is a 3D game-like platform tailored for agent-based AI research. [...] The DeepMind Lab aims to combine several different AI research areas into one environment. Researchers will be able to test their AI agent's abilities on navigation, memory, and 3D vision, while determining how good they are at planning and strategy.

Netflix Keeping Bandwidth Usage Low By Encoding Its Video With VP9 and H.264/AVC Codecs (slashgear.com) 59

Netflix announced last week that it is getting offline video downloads support. The company has since shared that it is using VP9 video compression codec to ensure that the file sizes don't weigh a lot. An anonymous reader shares an article on Slashgear (edited): For streaming content, Netflix largely relies on H.264/AVC to reduce the bandwidth, but for downloading content, it uses VP9 encoding. VP9 can allow better quality videos for the same amount of data needed to download. The challenge is that VP9 isn't supported by all streaming providers -- it is supported on Android devices and via the Chrome browser. So to get around that lack of support on iOS, Netflix is offering downloads in H.264/AVC High whereas streams are encoded in H.264/AVC Main on such devices. Netflix chooses the optimal encoding format for each title on its service after finding, for instance, that animated films are easier to encode than live-action. Netflix says that H.264 High encoding saves 19% bandwidth compared to other encoding standards while VP9 saves 36%.

New Google Trusted Contacts Service Shares User Location In Real Time (onthewire.io) 78

Reader Trailrunner7 writes: Google has spent a lot of time and money on security over the last few years, developing new technologies and systems to protect users' devices. One of the newer technologies the company has come up with is designed to provide security for users themselves rather than their laptops or phones.

On Monday Google launched a new app for Android called Trusted Contacts that allows users to share their locations and some limited other information with a set of close friends and family members. The system is a two-way road, so a user can actively share her location with her Trusted Contacts, and stop sharing it at her discretion. But, when a problem or potential emergency comes up, one of those contacts can request to get that user's location to see where she is at any moment. The app is designed to give users a way to reassure contacts that they're safe, or request help if there's something wrong.

Amazon Unveils 'Self-driving' Brick-and-Mortar Convenience Store (seattletimes.com) 103

Amazon announced Monday it has built a convenience store in downtown Seattle that deploys a gaggle of technologies similar to those used in self-driving cars to allow shoppers to come in, grab items and walk out without going through a register (Editor's note: the link could be paywalled; alternate source). From a report on Seattle Times: The 1,800 square-foot store, officially dubbed "Amazon Go," is the latest beach in brick-and-mortar retail stormed by the e-commerce giant, which already has bookstores and is working on secretive drive-through grocery locations. It's clearly a sign that Amazon sees a big opportunity in revolutionizing the staid traditions of Main Street commerce. Located on the corner of Seventh Avenue and Blanchard Street, the store is open to Amazon employees participating in a testing program. It is expected to be open to the public in early 2017.

Opera Developer Comes With Address Bar Speculative Prerenderer Feature (opera.com) 53

Earlier this month, Opera announced a new interesting feature with Opera 43 developer that predicts the website you're about to go to. The company explains: There are two ways we can predict what page the user will soon load. When the current page tells us so, and when we can determine from the users actions that they are about to load something. Pages can use the tag, and for instance Google uses that for search results if they are pretty sure of what you will load next. When someone writes in the address bar they are humanly slow. Sometimes it is obvious what they will write after just 1-2 characters but they will just keep writing or arrowing through suggestions for millions or billions of wasted clock cycles. We expect this feature to results in an average of 1 second faster loads from the address bar. The company insists that this feature saves time and energy without compromising the security. What's your thought?

Embedding Isn't Copyright Infringement, Says Italian Court (arstechnica.co.uk) 22

The appeal court of Rome has overturned one of the 152 website blocks another court imposed last month, and ruled that embedding does not constitute a copyright infringement. From an ArsTechnica report: The order against the Italian site Kisstube is annulled, but the other websites remain blocked. Kisstube is a YouTube channel, which also exists as a standalone website that does not host any content itself, linking instead to YouTube. Both the channel and website arrange content by categories for the convenience of users. The Italian court's decision was informed by an important ruling by the Court of Justice of the European Union (CJEU). In the BestWater case, the CJEU held that embedding or framing a video or image from another website is not copyright infringement if the latter is already accessible to the general public. However, another CJEU judgment ruled that posting hyperlinks to pirated copies of material is only legal provided it is done without knowledge that they are unauthorised versions, and it is not carried out for financial gain.

EU Threatens Twitter And Facebook With Possible 'Hate Speech' Laws (gizmodo.com) 279

An anonymous reader quotes Gizmodo: On Sunday, the European Commission warned Facebook, Twitter, Google, YouTube and Microsoft that if the companies do not address their hate speech problems, the EU will enact legislation that will force them to do so. In May, those five companies voluntarily signed a code of conduct to fight illegal hate speech on their platforms within 24 hours... But on Sunday, the European Commission revealed that the companies were not complying with this code in a satisfactory manner.

"In practice the companies take longer and do not yet achieve this goal. They only reviewed 40 percent of the recorded cases in less than 24 hours," a Commission official told Reuters. The Commission's report found that YouTube responded to reports of harassment the fastest, and unsurprisingly, Twitter found itself in last place. "If Facebook, YouTube, Twitter and Microsoft want to convince me and the ministers that the non-legislative approach can work, they will have to act quickly and make a strong effort in the coming months," Jourova told the Financial Times on Sunday.

BMW Traps A Car Thief By Remotely Locking His Doors (cnet.com) 304

An anonymous reader quotes CNET: Seattle police caught an alleged car thief by enlisting the help of car maker BMW to both track and then remotely lock the luckless criminal in the very car he was trying to steal... Turns out if you're inside a stolen car, it's perhaps not the best time to take a nap. "A car thief awoke from a sound slumber Sunday morning (November 27) to find he had been remotely locked inside a stolen BMW, just as Seattle police officers were bearing down on him," wrote Jonah Spangenthal-Lee [deputy director of communications for the Seattle Police Department].

The suspect found a key fob mistakenly left inside the BMW by a friend who'd borrowed the car from the owner and the alleged crime was on. But technology triumphed. When the owner, who'd just gotten married a day earlier, discovered the theft, the police contacted BMW corporate, who tracked the car to Seattle's Ravenna neighborhood.

The 38-year-old inside was then booked for both auto theft and possession of methamphetamine.

Ask Slashdot: Have You Read 'The Art of Computer Programming'? (wikipedia.org) 342

In 1962, 24-year-old Donald Knuth began writing The Art of Computer Programming, publishing three volumes by 1973, with volume 4 arriving in 2005. (Volume 4A appeared in 2011, with new paperback fascicles planned for every two years, and fascicle 6, "Satisfiability," arriving last December). "You should definitely send me a resume if you can read the whole thing," Bill Gates once said, in a column where he described working through the book. "If somebody is so brash that they think they know everything, Knuth will help them understand that the world is deep and complicated."

But now long-time Slashdot reader Qbertino has a question: I've had The Art of Computer Programming on my book-buying list for just about two decades now and I'm still torn...about actually getting it. I sometimes believe I would mutate into some programming demi-god if I actually worked through this beast, but maybe I'm just fooling myself...

Have any of you worked through or with TAOCP or are you perhaps working through it? And is it worthwhile? I mean not just for bragging rights. And how long can it reasonably take? A few years?

Does Windows 10's Data Collection Trade Privacy For Microsoft's Security? (pcworld.com) 147

jader3rd shares an article from PC World arguing that Windows 10's data collection "trades your privacy for Microsoft's security." [Anonymized] usage data lets Microsoft beef up threat protection, says Rob Lefferts, Microsoft's director of program management for Windows Enterprise and Security. The information collected is used to improve various components in Windows Defender... For example, Windows Defender Application Guard for Microsoft Edge will put the Edge browser into a lightweight virtual machine to make it harder to break out of the browser and attack the operating system. With telemetry, Microsoft can see when infections get past Application Guard defenses and improve the security controls to reduce recurrences.

Microsoft also pulls signals from other areas of the Windows ecosystem, such as Active Directory, with information from the Windows 10 device to look for patterns that can indicate a problem like ransomware infections and other attacks. To detect those patterns, Microsoft needs access to technical data, such as what processes are consuming system resources, hardware diagnostics, and file-level information like which applications had which files open, Lefferts says. Taken together, the hardware information, application details, and device driver data can be used to identify parts of the operating system are exposed and should be isolated into virtual containers.

The article points out that unlike home users, enterprise users of Windows 10 can select a lower level of data-sharing, but argues that enterprises "need to think twice before turning off Windows telemetry to increase corporate privacy" because Windows Update won't work without information about whether previous updates succeeded or failed.

Canonical Sues Cloud Provider Over 'Unofficial' Ubuntu Images (ostatic.com) 46

An anonymous reader quotes OStatic's update on Canonical's lawsuit against a cloud provider: Canonical posted Thursday that they've been in a dispute with "a European cloud provider" over the use of their own homespun version of Ubuntu on their cloud servers. Their implementation disables even the most basic of security features and Canonical is worried something bad could happen and it'd reflect badly back on them... They said they've spent months trying to get the unnamed provider to use the standard Ubuntu as delivered to other commercial operations to no avail. Canonical feels they have no choice but to "take legal steps to remove these images." They're sure Red Hat and Microsoft wouldn't be treated like this.
Mark Shuttleworth, the founder of Ubuntu, wrote in his blog post that Ubuntu is "the leading cloud OS, running most workloads in public clouds today," whereas these homegrown images "are likely to behave unpredictably on update in weirdly creative and mysterious ways... We hear about these issues all the time, because users assume there is a problem with Ubuntu on that cloud; users expect that 'all things that claim to be Ubuntu are genuine', and they have a right to expect that...

"To count some of the ways we have seen home-grown images create operational and security nightmares for users: clouds have baked private keys into their public images, so that any user could SSH into any machine; clouds have made changes that then blocked security updates for over a week... When things like this happen, users are left feeling let down. As the company behind Ubuntu, it falls to Canonical to take action."
