  • Why Women Have No Time For Wikipedia

    Andreas Kolbe writes Wikipedia is well known to have a very large gender imbalance, with survey-based estimates of women contributors ranging from 8.5% to around 16%. This is a more extreme gender imbalance than even that of Reddit, the most male-dominated major social media platform, and it has a palpable effect on Wikipedia content. Moreover, Wikipedia editor survey data indicate that only 1 in 50 respondents is a mother – a good proportion of female contributors are in fact minors, with women in their twenties less likely to contribute to Wikipedia. Wikimedia Foundation efforts to address this "gender gap" have so far remained fruitless. Wikipedia's demographic pattern stands in marked contrast to female-dominated social media sites like Facebook and Pinterest, where women aged 18 to 34 are particularly strongly represented. It indicates that it isn't lack of time or family commitments that keep women from contributing to Wikipedia – women simply find other sites more attractive. Wikipedia's user interface and its culture of anonymity may be among the factors leading women to spend their online time elsewhere.

  • Statistics Losing Ground To CS, Losing Image Among Students

    theodp (442580) writes Unless some things change, UC Davis Prof. Norman Matloff worries that the Statistician could be added to the endangered species list. "The American Statistical Association (ASA) leadership, and many in Statistics academia," writes Matloff, "have been undergoing a period of angst the last few years, They worry that the field of Statistics is headed for a future of reduced national influence and importance, with the feeling that: [1] The field is to a large extent being usurped by other disciplines, notably Computer Science (CS). [2] Efforts to make the field attractive to students have largely been unsuccessful."

    Matloff, who has a foot in both the Statistics and CS camps, but says, "The problem is not that CS people are doing Statistics, but rather that they are doing it poorly. Generally the quality of CS work in Stat is weak. It is not a problem of quality of the researchers themselves; indeed, many of them are very highly talented. Instead, there are a number of systemic reasons for this, structural problems with the CS research 'business model'." So, can Statistics be made more attractive to students? "Here is something that actually can be fixed reasonably simply," suggests no-fan-of-TI-83-pocket-calculators-as-a-computational-vehicle Matloff. "If I had my druthers, I would simply ban AP Stat, and actually, I am one of those people who would do away with the entire AP program. Obviously, there are too many deeply entrenched interests for this to happen, but one thing that can be done for AP Stat is to switch its computational vehicle to R."

  • Among Gamers, Adult Women Vastly Outnumber Teenage Boys

    MojoKid writes: The Entertainment Software Association has just released its 2014 report on the state of the video game industry (PDF), and as the title of this post suggests, there have been some significant shifts since the last report. Let's tackle the most interesting one first: Females have become the dominant gamer, claiming 52% of the pie. That's impressive, but perhaps more so is the fact that women over the age of 18 represent 36% of the game-playing population, whereas boys aged 18 and under claim a mere 17%. Statistics like these challenge the definition of "gamer." Some might say that it's a stretch to call someone who only plays mobile games a "gamer" (Candy Crush anyone?). Mental hurdle aside, the reality is that anyone who plays games, regardless of the platform, is a gamer.

  • Students From States With Faster Internet Tend To Have Higher Test Scores

    An anonymous reader sends word of correlation found between higher internet speeds and higher test scores. Quoting: The numbers—first crunched by the Internet provider comparison site HSI — show a distinct trend between faster Internet and higher ACT test scores. On the high end, Massachusetts scores big with an average Internet speed of 13.1Mbps, and an average ACT test score of 24.1. Mississippi, on the other hand, has an average speed of just 7.6Mbps and an average score of 18.9.

    In between those two states, the other 48 fall in a positive correlation that, while not perfect, is quite undeniable. According to HSI's Edwin Ivanauskas, the correlation is stronger than that between household income and test scores, which have long been considered to be firmly connected to each other. The ACT scores were gathered from ACT.org, which has the official rankings and averages for the 2013 test, and the speed ratings were taken from Internet analytics firm Akamai's latest report.

  • 51% of Computer Users Share Passwords

    An anonymous reader writes Consumers are inadvertently leaving back doors open to attackers as they share login details and sign up for automatic log on to mobile apps and services, according to new research by Intercede. While 52% of respondents stated that security was a top priority when choosing a mobile device, 51% are putting their personal data at risk by sharing usernames and passwords with friends, family and colleagues. The research revealed that consumers are not only sharing passwords but also potentially putting their personal and sensitive information at risk by leaving themselves logged in to applications on their mobile devices, with over half of those using social media applications and email admitting that they leave themselves logged in on their mobile device.

  • Apple's Diversity Numbers: 70% Male, 55% White

    An anonymous reader writes: Apple has released a diversity report on the genders and races of its employees. As is common in the tech industry, the majority of Apple's workforce is male — only three out of 10 employees around the globe are female. Broken down, males compose 65 percent of non-tech workers, 80 percent of tech workers, and 72 percent of Apple's leadership.

    According to CEO Tim Cook, he's unhappy with Apple's diversity numbers and says Apple is working to improve them: "Apple is committed to transparency, which is why we are publishing statistics about the race and gender makeup of our company. Let me say up front: As CEO, I'm not satisfied with the numbers on this page. They're not new to us, and we've been working hard for quite some time to improve them. We are making progress, and we're committed to being as innovative in advancing diversity as we are in developing our products."

  • For Fast Internet in the US, Virginia Tops the Charts

    According to data gathered by Akamai, an analysis from Broadview Networks comes to the conclusion that the top five U.S. states for broadband speed are Virginia (at the top of the list, with an average transfer speed of 13.78 Mbps), Delaware, Massachusetts, Rhode Island, and Washington, with Washington, D.C. slightly edging out the similarly-named state; Alaska comes in dead last. These are average speeds, though, and big states have more variation to account for, including connections in the hinterlands. You could still have a fast connection in Chattanooga, or be stuck on dial-up in the Texas panhandle.

  • Windows XP Falls Below 25% Market Share, Windows 8 Drops Slightly

    An anonymous reader writes: Despite support for Windows XP finally ending three months ago, the ancient OS has only now fallen below the 25 percent market share mark. To add to the bad news for Microsoft, after only nine full months of availability, its latest operating system version, Windows 8.1, has lost share for the first time. For desktop browser share, Chrome is up, taking mostly from Internet Explorer and Firefox. For mobile browsers, Safari continues to fall while Chrome maintains strong growth.

  • Jesse Jackson: Tech Diversity Is Next Civil Rights Step

    theodp writes: U.S. civil rights leader Rev. Jesse Jackson called on the Obama administration Monday to scrutinize the tech industry's lack of diversity. "There's no talent shortage. There's an opportunity shortage," Jackson said, calling Silicon Valley "far worse" than many others, such as car makers that have been pressured by unions. He said tech behemoths have largely escaped scrutiny by a public dazzled with their cutting-edge gadgets. Jackson spoke to press after meeting with Labor Secretary Tom Perez for a review of H-1B visas, arguing that data show Americans have the skills and should have first access to high-paying tech work. Jackson's Rainbow Push Coalition plans to file a freedom-of-information request next month with the EEOC to acquire employment data for companies that have not yet disclosed it publicly, which includes Amazon, Broadcom, Oracle, Qualcomm and Yelp. Unlike the Dept. of Labor, Jackson isn't buying Silicon Valley's argument that minority hiring statistics are trade secrets. Five years after Google's HR Chief would only reassure Congress the company had "a very strong internal Black Googler Network" and its CEO brushed off similar questions about its diversity numbers by saying "we're pretty happy with the way our recruiting work," Google — under pressure from Jackson — fessed up to having a tech workforce that's only 1% Black, apparently par for the course in Silicon Valley.

  • Better Living Through Data

    jradavenport (3020071) writes "Using two years of continuous monitoring of my MacBook Air battery usage (once every minute), I have been able to study my own computer use patterns in amazing detail. This dataset includes 293k measurements, or more than 204 days of use over two years. I use the laptop over 50 hours per week on average, and my most productive day is Tuesday. Changes in my work/life balance have begun to appear over the two-year span, and I am curious whether such data can help inform how much computer use is healthy/productive."

  • OKCupid Experiments on Users Too

    With recent news that Facebook altered users' feeds as part of a psychology experiment, OKCupid has jumped in and noted that they too have altered their algorithms and experimented with their users (some unintentional) and "if you use the Internet, you’re the subject of hundreds of experiments at any given time, on every site. That’s how websites work." Findings include that removing pictures from profiles resulted in deeper conversations, but as soon as the pictures returned appearance took over; personality ratings are highly correlated with appearance ratings (profiles with attractive pictures and no other information still scored as having a great personality); and that suggesting a bad match is a good match causes people to converse nearly as much as ideal matches would.

  • 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.

    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."
