  • Internet Census 2012 Data Examined: Authentic, But Chaotic and Unethical

    An anonymous reader writes "A team of researchers at the TU Berlin and RWTH Aachen presented an analysis of the Internet Census 2012 data set (here's the PDF) in the July edition of the ACM Sigcomm Computer Communication Review journal. After its release on March 17, 2013 by an anonymous author, the Internet Census data created an immediate media buzz, mainly due to its unethical data collection methodology that exploited default passwords to form the Carna botnet. The now published analysis suggests that the released data set is authentic and not faked, but also reveals a rather chaotic picture. The Census suffers from a number of methodological flaws and also lacks meta-data information, which renders the data unusable for many further analyses. As a result, the researchers have not been able to verify several claims that the anonymous author(s) made in the published Internet Census report. The researchers also point to similar but legal efforts measuring the Internet and remark that the illegally measured Internet Census 2012 is not only unethical but might have been overrated by the press."

  • Do Apple and Google Sabotage Older Phones? What the Graphs Don't Show

    Harvard economics professor Sendhil Mullainathan takes a look in the New York Times at interesting correlations between the release dates of new phones and OSes and search queries that indicate frustration with the speed of the phones that people already have. Mullainathan illustrates with graphs (and gives plausible explanations for the difference) just how different the curves are over time for the search terms "iPhone slow" and "Samsung Galaxy slow." It's easy to see with the iPhone graph especially how it could seem to users that Apple has intentionally slowed down older phones to nudge them toward upgrading. While he's careful not to rule out intentional slowing of older phone models (that's possible, after all), Mullainathan cites several factors that mean there's no need to believe in a phone-slowing conspiracy, and at least two big reasons (reputation, liability) for companies — Apple, Google, and cellphone manufacturers like Samsung — not to take part in one. He points out various wrinkles in what the data could really indicate, including genuine but innocent slowdowns caused by optimizing for newer hardware. It's an interesting look at the difference between having mere statistics, no matter how rigorously gathered, and knowing quite what they mean.

  • AP Computer Science Test Takers Up 8,000; Pass Rate Down 6.8%

    theodp (442580) writes "Code.org reports that preliminary data on students who took the Advanced Placement (AP) Computer Science Exam in 2014 show an increase of 8,276 students over 2013 and represent what the College Board called "the first real indication of progress in AP CS enrollment for women and underserved minorities in years." Girls made up 20% of the 39,393 total test takers, compared to 18.7% of the 31,117 test takers in 2013. Black or African American students saw their share increase by 0.19%, from 3.56% to 3.75% (low, but good enough to crush Twitter). Code.org credits the increased enrollment to its celebrity-studded CS promo film starring Bill Gates and Mark Zuckerberg ("I even made a personal bet (reflected in my contractual commitment to Code.org donors) that our video could help improve the seemingly immovable diversity numbers in computer science," Code.org founder Hadi Partovi notes). However, some of the increase is likely attributable to the other efforts of Code.org's donors. Microsoft ramped up its TEALS AP CS program in 2013-2014, and — more significantly — Google helped boost AP CS study not only through its CS4HS program, but also by funding the College Board's AP STEM Access program, which offered $5 million to schools and teachers to encourage minority and female students to enroll in AP STEM courses. This summer, explains the College Board, "All AP STEM teachers in the participating schools (not just the new AP STEM teachers), who increase diversity in their class, receive a [$100] DonorsChoose.org gift card for each student in the course who receives a 3, 4, or 5 on the AP Exam." The bad news for AP CS teachers anticipating Google "Excellence Funding" bounties (for increasing course enrollment and completion "by at least five underrepresented students") is that AP CS pass rates decreased to 60.8% in 2014 (from 67.6% in 2013), according to Total Registration. Using these figures and a back-of-the-envelope calculation, while enrollment saw a 26.6% increase over last year, the total number of students passing increased by 13.9%."

  • Google Looking To Define a Healthy Human

    rtoz writes: Google's moonshot research division, "Google X," has started "Baseline Study," a project designed to collect anonymous genetic and molecular information from 175 people (and later thousands more) to create a complete picture of what a healthy human being should be. The blueprint will help researchers detect health problems such as heart disease and cancer far earlier, focusing medicine on prevention rather than treatment. According to Google, the information from Baseline will be anonymous, and its use will be limited to medical and health purposes. Data won't be shared with insurance companies.

  • One Trillion Bq Released By Nuclear Debris Removal At Fukushima So Far

    AmiMoJo writes The operator of the damaged Fukushima Daiichi nuclear plant says more than one trillion becquerels of radioactive substances were released as a result of debris removal work at one of the plant's reactors. Radioactive cesium was detected at levels exceeding the government limit in rice harvested last year in Minami Soma, some 20 kilometers from Fukushima Daiichi. TEPCO presented the Nuclear Regulation Authority with an estimate that the removal work discharged 280 billion becquerels per hour of radioactive substances, or a total of 1.1 trillion becquerels. The plant is believed to be still releasing an average of 10 million becquerels per hour of radioactive material.

  • For Half, Degrees In Computing, Math, Or Stats Lead To Other Jobs

    dcblogs (1096431) writes The Census Bureau reports that only 26% of people with any type of four-year STEM degree are working in a STEM field. For those with a degree specifically in computer, math or statistics, the figure is 49%, nearly the same for engineering degrees. What happens to the other STEM trained workers? The largest numbers are managers at non-STEM businesses (22.5%), or having careers in education (17.7%), business/finance (13.2%) and office support (11.5%). Some other data points: Among those with college degrees in computer-related occupations, men are paid more than women ($90,354 vs. $78,859 on average), and African American workers are more likely to be unemployed than white or Asian workers.

  • People Who Claim To Worry About Climate Change Don't Cut Energy Use

    schwit1 (797399) writes with news that a UK study has found that folks concerned about climate change don't do much to conserve power at home. From the article: Those who say they are concerned about the prospect of climate change consume more energy than those who say it is "too far into the future to worry about," the study commissioned by the Department for Energy and climate change found. That is in part due to age, as people over 65 are more frugal with electricity but much less concerned about global warming. However, even when pensioners are discounted, there is only a "weak trend" to show that people who profess to care about climate change do much to cut their energy use. The findings were based on the Household Electricity Survey, which closely monitored the electricity use and views of 250 families over a year. The report (PDF), by experts from Loughborough University and Cambridge Architectural Research, was commissioned and published by DECC. High power use doesn't have to be dirty: Replace coal, methane, and petroleum with nuclear, wind, solar, etc.

  • Indie Game Developers Talk About Why They Struck Out On Their Own

    Nerval's Lobster (2598977) writes Technology writer Jon Brodkin sat down with a group of indie game developers (as well as a professor at the University of Southern California's game-design program) to talk about why they decided to launch their own small studios rather than stick with comfortable (albeit stressful) jobs at major firms like Disney or Zynga. The answer, as you'd expect, boils down to control. "Working for a bigger company is a good way to gain experience, and learn how games are made," said Graham Smith, one of the co-founders of Toronto-based DrinkBox Studios. "It's also nice to have a steady salary coming in as you learn the ropes. On the flip side, depending on the company, you might not have much control over the game's design, or even be making the types of games that you enjoy playing." But startups come with their own challenges, not the least of which is the prospect of an economic downturn quickly wiping you out, or not making your Kickstarter goal.

  • The World's Best Living Programmers

    itwbennett (1594911) writes "How do you measure success? If it's by Stack Overflow reputation, Google engineer Jon Skeet is the world's best programmer. If it's winning programming competitions, Gennady Korotkevich or Petr Mitrechev might be your pick. But what about Linus Torvalds? Or Richard Stallman? Or Donald Knuth? ITworld's Phil Johnson has rounded up a list of what just might be the world's top 14 programmers alive today."

  • IEEE Spectrum Ranks the Top Programming Languages

    An anonymous reader writes Working with computational journalist Nick Diakopoulos, we at IEEE Spectrum have published an app that ranks the popularity of dozens of programming languages. Because different fields have different interests (what's popular with programmers writing embedded code versus what's hot with web developers isn't going to be identical) we tried to make the ranking system as transparent as possible — you can use our presets or you can go in and create your own customized ranking by adjusting the individual weightings of the various data sources we mined.

  • How Often Do Economists Commit Misconduct?

    schwit1 (797399) writes A survey of professional academic economists finds that a large percentage are quite willing to cheat or fake data to get the results they want. From the paper's abstract: "This study reports the results of a survey of professional, mostly academic economists about their research norms and scientific misbehavior. Behavior such as data fabrication or plagiarism are (almost) unanimously rejected and admitted by less than 4% of participants. Research practices that are often considered 'questionable,' e.g., strategic behavior while analyzing results or in the publication process, are rejected by at least 60%. Despite their low justifiability, these behaviors are widespread. Ninety-four percent report having engaged in at least one unaccepted research practice."

    That less than 4% engage in "data fabrication or plagiarism" might seem low, but it is a terrible statistic . ... 40% admit to doing what they agree are "questionable" research practices, while 94% admit to committing "at least one unaccepted research practice." In other words, almost none of these academic economists can be trusted in the slightest. As the paper notes, "these behaviors are widespread.""

  • Researchers Claim Wind Turbine Energy Payback In Less Than a Year

    mdsolar (1045926) writes "Researchers have carried out an environmental lifecycle assessment of 2-megawatt wind turbines mooted for a large wind farm in the U.S. Pacific Northwest. They conclude that in terms of cumulative energy payback, or the time to produce the amount of energy required of production and installation, a wind turbine with a working life of 20 years will offer a net benefit within five to eight months of being brought online." Watts Up With That? has a more skeptical take on the calculations.

  • Swedish Farmers Have Doubts About Climatologists and Climate Change

    cold fjord (826450) writes with this excerpt from ScienceNordic: Researchers the world over almost unanimously agree that our climate is changing ... But many farmers – at least Swedish ones – have experienced mild winters and shifting weather before and are hesitant about trusting the scientists. The researcher who discovered the degree of scepticism among farmers was surprised by her findings. Therese Asplund ... was initially looking into how agricultural magazines covered climate change. Asplund found after studying ten years of issues of the two agricultural sector periodicals ATL and Land Lantbruk that they present climate change as scientifically confirmed, a real problem. But her research took an unexpected direction when she started interviewing farmers in focus groups about climate issues. Asplund had prepared a long list of questions about how the farmers live with the threat of climate change and what they plan to do to cope with the subsequent climate challenges. The conversations took a different course: "They explained that they didn't quite believe in climate changes," she says. "Or at least that these are not triggered by human activities."

  • How Apple Can Take Its Headphones To the Next Level

    redletterdave (2493036) writes "Apple is one of the biggest headphone makers in the world thanks to those signature white earbuds that have shipped with every iPod, iPhone, and iPad since 2001. But even two years after earbuds became 'EarPods,' the design could still be improved — and competitors are taking notice. Amazon recently unveiled a new pair of in-ear headphones that are magnetic, tangle-free and $5 cheaper than Apple's $30 EarPods, while smaller startups are promoting their own wireless and customizable 3D-printed earbuds. But Apple has an ace up its sleeve, in the form of patents for a set of headphones with 'one or more integrated physiological sensors' designed to help users keep track of their body stats."

  • Google Is Offering Free Coding Lessons To Women and Minorities

    redletterdave writes: According to a blog post from Gregg Pollack, CEO of the Code School, Google is paying for three free months for any women and minorities interested in tech to expand their skills. The offer is part of Google's $50 million "Made With Code" initiative, which aims to help close the gender gap in tech. While Google is also offering the same vouchers to the women in attendance at its annual I/O developers conference this week, the search giant has released an online application that's available to women everywhere. Google says its available vouchers for women number in the "thousands."

  • Larry Page: Healthcare Data Mining Could Save 100,000 Lives a Year

    An anonymous reader writes Google often gets criticism for its seemingly boundless desire for data collection and analysis, but the company says it has higher ambitions than just figuring out how best to serve advertising. Speaking to the NY Times, Larry Page said, "We get so worried about these things that we don't get the benefits Right now we don't data-mine healthcare data. If we did we'd probably save 100,000 lives next year." By "these things," he means privacy concerns and fear that the data might be misused. But he also pointed to Street View as a case where privacy concerns mostly melted away after people used it and found it helpful. "In the early days of Street View, this was a huge issue, but it's not really a huge issue now. People understand it now and it's very useful. And it doesn't really change your privacy that much. A lot of these things are like that."

  • CDC: 1 In 10 Adult Deaths In US Caused By Excessive Drinking

    An anonymous reader writes: According to new research from the CDC, 9.8% of deaths in working-age adults (22-64 years old) in the U.S. from 2006 to 2010 were "attributable to excessive drinking." This makes excessive drinking the fourth leading cause of preventable death in the U.S. The study included deaths from medical conditions, such as liver disease and alcohol-induced strokes, as well as deaths from alcohol-related events, like car accidents, homicides, and fall injuries. However, it did not account for cases where excessive alcohol consumption was a factor in contracting conditions like AIDS, pneumonia, and tuberculosis, so the count may actually be higher. Many western states with low population spread out over a large area showed the highest alcohol-related death rates, while states from the east coast and the midwest tended to be on the lower end of the spectrum. The study also tracked years of life lost, which is higher for alcohol-related deaths than for most other types of death. Researcher Robert Brewer said, "One of the issues with alcohol that is particularly tragic is the extent to which it gets people in the prime of their lives."

  • Google I/O 2014 Begins [updated]

    Google I/O, the company's annual developer tracking^wdevelopers conference, has opened today in San Francisco. This year the company has reduced the number of conference sessions to 80, but also promised a broader approach than in previous years -- in other words, there may be a shift in focus a bit from Google's best known platforms (Chrome/Chrome OS and Android). Given its wide-ranging acquisitions and projects (like the recent purchase of Nest, which itself promptly bought Dropcam, the ever smarter fleet of self-driving cars, the growing number of Glass devices in the wild, and the announcement of a 3D scanning high end tablet quite unlike the Nexus line of tablets and phones), there's no shortage of edges to focus on. Judging from the booths set up in advance of the opening (like one with a sign announcing "The Physical Web," expect some of the stuff that gets lumped into "the Internet of Things." Watch this space -- updates will appear below -- for notes from the opening keynote, or follow along yourself with the live stream, and add your own commentary in the comments. In the days to come, watch for some video highlights of projects on display at I/O, too. Update: 06/25 17:41 GMT by T : Updates rolling in below on Android, wearables, Android in cars, Chromecast, smart watches, etc.Keep checking back! (Every few minutes, I get another chunk in there.)

  • NOAA: Earth Smashed A Record For Heat In May 2014, Effects To Worsen

    Freshly Exhumed (105597) writes with news that NOAA's latest global climate analysis is showing things are getting hotter. From the article: Driven by exceptionally warm ocean waters, Earth smashed a record for heat in May and is likely to keep on breaking high temperature marks, experts say. The National Oceanic and Atmospheric Administration Monday said May's average temperature on Earth of 15.54 C beat the old record set four years ago. In April, the globe tied the 2010 record for that month. Records go back to 1880. Experts say there's a good chance global heat records will keep falling, especially next year because an El Nino weather event is brewing on top of man-made global warming. An El Nino is a warming of the eastern tropical Pacific Ocean that alters climate worldwide and usually spikes global temperatures.
