Google Unveils 72-Qubit Quantum Computer With Low Error Rates

Mon, 03/05/2018 - 18:30
An anonymous reader quotes a report from Tom's Hardware: Google announced a 72-qubit universal quantum computer that promises the same low error rates the company saw in its first 9-qubit quantum computer. Google believes that this quantum computer, called Bristlecone, will be able to bring us to an age of quantum supremacy. In a recent announcement, Google said: "If a quantum processor can be operated with low enough error, it would be able to outperform a classical supercomputer on a well-defined computer science problem, an achievement known as quantum supremacy. These random circuits must be large in both number of qubits as well as computational length (depth). Although no one has achieved this goal yet, we calculate quantum supremacy can be comfortably demonstrated with 49 qubits, a circuit depth exceeding 40, and a two-qubit error below 0.5%. We believe the experimental demonstration of a quantum processor outperforming a supercomputer would be a watershed moment for our field, and remains one of our key objectives." According to Google, a minimum error rate for quantum computers needs to be in the range of less than 1%, coupled with close to 100 qubits. Google seems to have achieved this so far with 72-qubit Bristlecone and its 1% error rate for readout, 0.1% for single-qubit gates, and 0.6% for two-qubit gates. Quantum computers will begin to become highly useful in solving real-world problems when we can achieve error rates of 0.1-1% coupled with hundreds of thousand to millions of qubits. According to Google, an ideal quantum computer would have at least hundreds of millions of qubits and an error rate lower than 0.01%. That may take several decades to achieve, even if we assume a "Moore's Law" of some kind for quantum computers (which so far seems to exist, seeing the progress of both Google and IBM in the past few years, as well as D-Wave).

Oculus Rift Is Now the Most Popular VR Headset On Steam

Mon, 03/05/2018 - 17:50
The Oculus Rift has overtaken the HTC Vive on the monthly Steam hardware survey for the first time since the launch of both headsets in early 2016. VentureBeat reports: The survey is entirely optional and scans a user's PC for various hardware components, including any VR headsets that may be connected. After a few months of catching up to Vive, the Rift was neck-and-neck with its rival in January's survey with 0.9 percent between the two. However, February saw Oculus step past HTC; Rift took 47.31 percent of the total hardware use, and Vive fell to 45.38 percent, leaving just under 2 percent between them. It's still a tight race, then, but this is the first time Rift has managed to surpass Vive. Again, this is in no way confirmation that the Oculus Rift has sold more units than the HTC Vive, as neither headset has had official sales figures released, but it's the best shot we've got at gauging the market share right now. Rift also took the "Most Popular Headset" space in Steam's individual listings for the second time ever.

Rhode Island Bill Would Impose Fee For Accessing Online Porn

Mon, 03/05/2018 - 17:10
If a recently introduced bill passes the General Assembly this session, Rhode Island residents will have to pay a $20 fee to access sexually explicit content online. The bill, introduced by Sen. Frank Ciccone (D-Providence) and Sen. Hanna Gallo (D-Cranston), would require internet providers to digitally block "sexual content and patently offensive material." Consumers could then deactivate that block for a fee of $20. The Providence Journal reports: Each quarter the internet providers would give the money made from the deactivation fees to the state's general treasurer, who would forward the money to the attorney general to fund the operations of the Council on Human Trafficking, according to the bill's language. If online distributors of sexual content do not comply with the filter, the attorney general or a consumer could file a civil suit of up to $500 for each piece of content reported, but not blocked, according to the bill.

Six Tech Companies Filing Net Neutrality Lawsuit

Mon, 03/05/2018 - 16:33
An anonymous reader quotes a report from The Hill: Six technology companies, including Kickstarter, Foursquare and Etsy, have launched a lawsuit against the Federal Communications Commission (FCC) in an effort to preserve net neutrality rules. The companies, which also include Shutterstock, Expa and Automattic, on Monday filed their petition with the U.S. Court of Appeals for the District of Columbia Circuit. The companies join Vimeo and Mozilla, as well as several state attorneys general who have also filed lawsuits against the FCC in support of the net neutrality rules. Like the other lawsuits, their new case hinges on the Administrative Procedure Act, which they argue prevents the FCC from "arbitrary and capricious" redactions to already existing policy. "Already, over 30,000 Etsy sellers participated in the FCC's public comment process, and tens of thousands more reached out to Congress in support of net neutrality. Now we're bringing their stories and experiences to the courts," said Althea Erickson, head of advocacy and impact at Etsy.

Ubisoft is Using AI To Catch Bugs in Games Before Devs Make Them

Mon, 03/05/2018 - 15:30
AI has a new task: helping to keep the bugs out of video games. From a report: At the recent Ubisoft Developer Conference in Montreal, the French gaming company unveiled a new AI assistant for its developers. Dubbed Commit Assistant, the goal of the AI system is to catch bugs before they're ever committed into code, saving developers time and reducing the number of flaws that make it into a game before release. "I think like many good ideas, it's like 'how come we didn't think about that before?'," says Yves Jacquier, who heads up La Forge, Ubisoft's R&D division in Montreal. His department partners with local universities including McGill and Concordia to collaborate on research intended to advance the field of artificial intelligence as a whole, not just within the industry. La Forge fed Commit Assistant with roughly ten years' worth of code from across Ubisoft's software library, allowing it to learn where mistakes have historically been made, reference any corrections that were applied, and predict when a coder may be about to write a similar bug. "It's all about comparing the lines of code we've created in the past, the bugs that were created in them, and the bugs that were corrected, and finding a way to make links [between them] to provide us with a super-AI for programmers," explains Jacquier.

Remote Work is Going To Keep Increasing, Study Says

Mon, 03/05/2018 - 14:48
Freelancing website Upwork has published its annual Future Workforce Report, which explores hiring behaviors of over 1,000 U.S. managers. It finds: As companies struggle to fill the skills gap, they're embracing agile, remote teams to get work done. Nearly two-thirds (63 percent) of companies today have remote workers, yet a majority lack remote work policies. Companies have the resources, but lack the policies to support remote work: While companies feel confident they have the resources in place to support remote work, many lack a formal policy. Sixty-four percent of hiring managers feel that their company has the resources and processes in place to support a remote workforce, yet the majority (57 percent) lack a remote work policy. Companies with work-from-home policies have become more lenient & inclusive: As companies increasingly embrace remote work, they're evolving their work-from-home policies. Nearly half (45%) of hiring managers said their company's work-from-home policy has changed in the past five years, with 60 percent saying it has become more lenient and inclusive. This increased inclusivity is making it easier for companies to find the talent they need. Over half (52%) of hiring managers that work at companies with work-from-home policies believe hiring has become easier in the past year. Findings indicate remote work is likely to become the new normal: Over half (55%) of hiring managers agree that remote work has become more commonplace as compared to three years ago. Five times as many hiring managers expect more of their team to work remotely in the next ten years than expect less.

Microsoft To Offer Governments Local Version of Azure Cloud Service

Mon, 03/05/2018 - 14:12
Microsoft on Monday said it will soon make it possible for government clients to run its cloud technology on their own servers as part of a concerted effort to make Azure more appealing to local and federal agencies. From a report: The pairing of Azure Stack, Microsoft's localized cloud product, and Azure Government, the government-tailored version of Microsoft's cloud, comes as competition against Amazon.com Inc for major clients in the public sector ramps up. The new offering, which will be made available in mid-2018, is designed to appeal to governments and agencies with needs for on-premise servers, such as in a military operation or in an embassy abroad, said Tom Keane, Microsoft Azure's head of global infrastructure.

Mysterious $15,000 'GrayKey' Promises To Unlock iPhone X For The Feds

Mon, 03/05/2018 - 12:50
Thomas Fox-Brewster, reporting for Forbes: Just a week after Forbes reported on the claim of Israeli U.S. government manufacturer Cellebrite that it could unlock the latest Apple iPhone models, another service has emerged promising much the same. Except this time it comes from an unkown entity, an obscure American startup named Grayshift, which appears to be run by long-time U.S. intelligence agency contractors and an ex-Apple security engineer. In recent weeks, its marketing materials have been disseminated around private online police and forensics groups, offering a $15,000 iPhone unlock tool named GrayKey, which permits 300 uses. That's for the online mode that requires constant connectivity at the customer end, whilst an offline version costs $30,000. The latter comes with unlimited uses. Another ad showed Grayshift claiming to be able to unlock iPhones running iOS 10 and 11, with iOS 9 support coming soon. It also claims to work on the latest Apple hardware, up to the iPhone 8 and X models released just last year. In a post from one private Google group, handed to Forbes by a source who asked to remain anonymous, the writer indicated they'd been demoed the technology and that it had opened an iPhone X.

Do Neural Nets Dream of Electric Sheep?

Mon, 03/05/2018 - 12:20
An anonymous reader shares a post: If you've been on the internet today, you've probably interacted with a neural network. They're a type of machine learning algorithm that's used for everything from language translation to finance modeling. One of their specialties is image recognition. Several companies -- including Google, Microsoft, IBM, and Facebook -- have their own algorithms for labeling photos. But image recognition algorithms can make really bizarre mistakes. Microsoft Azure's computer vision API added the above caption and tags. But there are no sheep in the image. None. I zoomed all the way in and inspected every speck. It also tagged sheep in this image. I happen to know there were sheep nearby. But none actually present. Here's one more example. In fact, the neural network hallucinated sheep every time it saw a landscape of this type. What's going on here? Are neural networks just hyper-vigilant, finding sheep everywhere? No, as it turns out. They only see sheep where they expect to see them. They can find sheep easily in fields and mountainsides, but as soon as sheep start showing up in weird places, it becomes obvious how much the algorithms rely on guessing and probabilities. Bring sheep indoors, and they're labeled as cats. Pick up a sheep (or a goat) in your arms, and they're labeled as dogs.

Facebook Asks Users: Should We Allow Men To Ask Children For Sexual Images?

Mon, 03/05/2018 - 11:32
Alex Hern, writing for The Guardian: Facebook has admitted it was a "mistake" to ask users whether paedophiles requesting sexual pictures from children should be allowed on its website. On Sunday, the social network ran a survey for some users asking how they thought the company should handle grooming behaviour. "There are a wide range of topics and behaviours that appear on Facebook," one question began. "In thinking about an ideal world where you could set Facebook's policies, how would you handle the following: a private message in which an adult man asks a 14-year-old girl for sexual pictures." The options available to respondents ranged from "this content should not be allowed on Facebook, and no one should be able to see it" to "this content should be allowed on Facebook, and I would not mind seeing it." A second question asked who should decide the rules around whether or not the adult man should be allowed to ask for such pictures on Facebook. Options available included "Facebook users decide the rules by voting and tell Facebook" and "Facebook decides the rules on its own."

New LTE Attacks Can Snoop On Messages, Track Locations, and Spoof Emergency Alerts

Sun, 03/04/2018 - 23:04
An anonymous reader quotes a report from ZDNet: A slew of newly discovered vulnerabilities can wreak havoc on 4G LTE network users by eavesdropping on phone calls and text messages, knocking devices offline, and even spoofing emergency alerts. Ten attacks detailed in a new paper by researchers at Purdue University and the University of Iowa expose weaknesses in three critical protocol operations of the cellular network, such as securely attaching a device to the network and maintaining a connection to receive calls and messages. Those flaws can allow authentication relay attacks that can allow an adversary to connect to a 4G LTE network by impersonating an existing user -- such as a phone number. Although authentication relay attacks aren't new, this latest research shows that they can be used to intercept message, track a user's location, and stop a phone from connecting to the network. By using common software-defined radio devices and open source 4G LTE protocol software, anyone can build the tool to carry out attacks for as little as $1,300 to $3,900, making the cost low enough for most adversaries. The researchers aren't releasing the proof-of-concept code until the flaws are fixed, however.

Ask Slashdot: Best To-Do/Task List Software?

Sun, 03/04/2018 - 21:02
Albanach writes: Despite searching, I have not identified a good solution for managing to-do lists, a problem that can't be unique or unusual. For a variety of reasons, I need something I host myself, which allows me to organize tasks, give them due dates and/or priorities and to easily reorganize. I'd prefer a web interface so that I can access my list from home/work/mobile. My searches generally turned up hosted solutions that don't work for privacy reasons, or very old software that has shown no sign of updates in years.

GitHub Survived the Biggest DDoS Attack Ever Recorded

Sun, 03/04/2018 - 18:23
A 1.35 terabit-per-second DDoS attack hit GitHub all at once last Wednesday. "It was the most powerful distributed denial of service attack recorded to date -- and it used an increasingly popular DDoS method, no botnet required," reports Wired. From the report: GitHub briefly struggled with intermittent outages as a digital system assessed the situation. Within 10 minutes it had automatically called for help from its DDoS mitigation service, Akamai Prolexic. Prolexic took over as an intermediary, routing all the traffic coming into and out of GitHub, and sent the data through its scrubbing centers to weed out and block malicious packets. After eight minutes, attackers relented and the assault dropped off. "We modeled our capacity based on fives times the biggest attack that the internet has ever seen," Josh Shaul, vice president of web security at Akamai told WIRED hours after the GitHub attack ended. "So I would have been certain that we could handle 1.3 Tbps, but at the same time we never had a terabit and a half come in all at once. It's one thing to have the confidence. It's another thing to see it actually play out how you'd hope." Akamai defended against the attack in a number of ways. In addition to Prolexic's general DDoS defense infrastructure, the firm had also recently implemented specific mitigations for a type of DDoS attack stemming from so-called memcached servers. These database caching systems work to speed networks and websites, but they aren't meant to be exposed on the public internet; anyone can query them, and they'll likewise respond to anyone. About 100,000 memcached servers, mostly owned by businesses and other institutions, currently sit exposed online with no authentication protection, meaning an attacker can access them, and send them a special command packet that the server will respond to with a much larger reply.

Bad iPhone Notches Are Happening To Good Android Phones

Sun, 03/04/2018 - 17:17
The Verge's Vlad Savov argues that Android smartphone manufacturers are copying the iPhone's design (specifically, the iPhone X's notch) with more speed and cynicism than ever before: I've been coming to Mobile World Congress for close to a decade now, and I've never seen the iPhone copied quite so blatantly and cynically as I witnessed during this year's show. MWC 2018 will go down in history as the launch platform for a mass of iPhone X notch copycats, each of them more hastily and sloppily assembled than the next. No effort is being made to emulate the complex Face ID system that resides inside Apple's notch; companies like Noa and Ulefone are in such a hurry to get their iPhone lookalike on the market that they haven't even customized their software to account for the new shape of the screen. More than one of these notched handsets at MWC had the clock occluded by the curved corner of the display. Asus is one of the biggest consumer electronics companies in the world, and yet its copycat notch is probably the most galling of them all. The Zenfone 5 looks and feels like a promising phone, featuring loud speakers, the latest Sony imaging sensor with larger-than-average pixels, and a price somewhere south of $499. I should be celebrating it right now, but instead I'm turning away in disgust as Asus leans into its copying by calling Apple a "Fruit Company" repeatedly. If you're going to copy the iPhone, at least have the decency to avoid trying to mock it. It would be stating the obvious to say that this trend is not a good one. I'm absolutely of the belief that everyone, Apple included, copies or borrows ideas from everyone else in the mobile industry. This is a great way to see technical improvements disseminated across the market. But the problem with these notched screens on Android phones is that they're purely cosmetic. Apple's notch at the top of the iPhone X allows the company to have a nearly borderless screen everywhere else, plus it accommodates the earpiece and TrueDepth camera for Face ID. Asus et al have a sizeable "chin" at the bottom of their phones, so the cutouts at the top are self-evidently motivated by the desire to just look -- not function, look -- like an iPhone X.

Google's Slack Competitor 'Hangouts Chat' Comes Out of Beta

Sun, 03/04/2018 - 16:11
Frederic Lardinois reports via TechCrunch: Hangouts Chat, Google's take on modern workplace communication, is now generally available and is becoming a core part of G Suite. Hangouts Chat was first announced at Google Cloud Next 2017, together with Hangouts Meet. While Meet went right into public availability, though, Chat went into an invite-only preview. Now, Google is rolling Chat out to all G Suite users over the course of the next seven days (so if you don't see it yet, don't despair). For all intents and purposes, Hangouts Chat is Google's take on Slack, Microsoft Teams and similar projects. Since Google first announced this project, Atlassian also joined the fray with the launch of Stride. Like its competitors, Chat is available on iOS, Android and the web. Chat currently supports 28 languages and each room can have up to 8,000 members. What's maybe just as important, though, is that Google has already built an ecosystem of partners that are integrating with Chat by offering their own bots. They include the likes of Xero, RingCentral, UberConference, Salesforce, Zenefits, Zoom.ai, Jira, Trello, Wrike and Kayak. There's even a Giphy bot. Developers can also build their own bots and integrate their own services with Chat.

Uber Challenges Study Suggesting Its Drivers Earn $3.37 Per Hour

Sun, 03/04/2018 - 14:09
An MIT study using data from more than 1,100 Uber and Lyft drivers concluded they're earning a median pretax profit of just $3.37 per hour. But now Reuters reports: Uber Chief Executive Dara Khosrowshahi criticized the MIT study in a tweet on Friday as "Mathematically Incompetent Theories (at least as it pertains to ride-sharing)," and linked to a response by Uber chief economist Jonathan Hall that challenged the study's methodology. Hall's rebuttal to the study said the likely misinterpretation of a survey question and the study's "inconsistent logic" produced a wage result that was below similar studies elsewhere. He said the study used a "flawed methodology" compared with a survey that found drivers' average hour earnings were $15.68. "The earnings figures suggested in the paper are less than half the hourly earnings numbers reported in the very survey the paper derives its data from," wrote Hall. The MIT study's lead author, Stephen Zoepf, told Reuters in an email on Saturday, "I can see how the question on revenue might have been interpreted differently by respondents" and called Hall's rebuttal thoughtful. "I'm re-running the analysis this weekend using Uber's more optimistic assumptions and should have new results and a public response acknowledging the discrepancy by Monday," he wrote. Saturday Uber's CEO tweeted a thank-you to MIT, "for listening and revisiting this study and its findings. Right thing to do."

Diabetes Is Actually Five Separate Diseases, Research Suggests

Sun, 03/04/2018 - 13:08
An anonymous reader quotes a report from the BBC: Scientists say diabetes is five separate diseases, and treatment could be tailored to each form. Diabetes, or uncontrolled blood sugar levels, is normally split into type 1 and type 2. But researchers in Sweden and Finland think the more complicated picture they have uncovered will usher in an era of personalized medicine for diabetes. The study, by Lund University Diabetes Centre in Sweden and the Institute for Molecular Medicine Finland, looked at 14,775 patients including a detailed analysis of their blood. The results, published in The Lancet Diabetes and Endocrinology, showed the patients could be separated into five distinct clusters: Cluster 1 - severe autoimmune diabetes is broadly the same as the classical type 1 -- it hit people when they were young, seemingly healthy and an immune disease left them unable to produce insulin Cluster 2 - severe insulin-deficient diabetes patients initially looked very similar to those in cluster 1 -- they were young, had a healthy weight and struggled to make insulin, but the immune system was not at fault Cluster 3 - severe insulin-resistant diabetes patients were generally overweight and making insulin but their body was no longer responding to it Cluster 4 - mild obesity-related diabetes was mainly seen in people who were very overweight but metabolically much closer to normal than those in cluster 3 Cluster 5 - mild age-related diabetes patients developed symptoms when they were significantly older than in other groups and their disease tended to be milder

Apple To Release a Cheaper MacBook Air Later This Year

Sun, 03/04/2018 - 12:07
According to Apple analyst Ming-Chi Kuo of KGI Securities, Apple doesn't appear to be axing its MacBook Air line, despite it being on the market for ten years. Kuo says Apple is planning to release a 13-inch MacBook Air "with a lower price tag" during the second quarter of 2018, which should help push MacBook shipments up by 10-15 percent this year. 9to5Mac reports: Details on the new MacBook Air are sparse, but this report from KGI corroborates a similarly vague report from Digitimes earlier this year. The MacBook Air line has been largely stagnate in recent years as Apple has shifted focus towards the 12-inch MacBook and MacBook Pro. Currently, Apple sells the 13-inch MacBook Air starting at $999, and KGI seems to think it will get even cheaper this year. Despite its neglect by Apple, the MacBook Air remains a popular choice for college students.

YouTube Hiring For Some Positions Excluded White and Asian Men, Lawsuit Says

Sun, 03/04/2018 - 11:06
Kirsten Grind and Douglas MacMillan report via The Wall Street Journal (Warning: source may be paywalled; alternative source): YouTube last year stopped hiring white and Asian males for technical positions because they didn't help the world's largest video site achieve its goals for improving diversity, according to a civil lawsuit filed by a former employee. The lawsuit, filed by Arne Wilberg, a white male who worked at Google for nine years, including four years as a recruiter at YouTube, alleges the division of Alphabet's Google set quotas for hiring minorities. Last spring, YouTube recruiters were allegedly instructed to cancel interviews with applicants who weren't female, black or Hispanic, and to "purge entirely" the applications of people who didn't fit those categories, the lawsuit claims. A Google spokeswoman said the company will vigorously defend itself in the lawsuit. "We have a clear policy to hire candidates based on their merit, not their identity," she said in a statement. "At the same time, we unapologetically try to find a diverse pool of qualified candidates for open roles, as this helps us hire the best people, improve our culture, and build better products." People familiar with YouTube's and Google's hiring practices in interviews corroborated some of the lawsuit's allegations, including the hiring freeze of white and Asian technical employees, and YouTube's use of quotas.
