theodp writes "On the final day of Computer Science Education Week, the Hour of Code bravado continues. Around 12:30 a.m. Sunday (ET), Code.org was boasting that in just 6 days, students of its tutorials have "written" more than 10x the number of lines of code in Microsoft Windows. "Students of the Code.org tutorials have written 507,152,775 lines of code. Is this a lot? By comparison, the Microsoft Windows operating system has roughly 50 million lines of code." Code.org adds, "In total, 15,481,846 students have participated in the Hour of Code. Of this group, 6,872,757 of them used the tutorials by Code.org, and within the Code.org tutorial, they've written 507,152,775 lines of code." On YouTube, however, a playlist of the Code.org tutorial videos has distinctly lower numbers, with only 2,246 views of the Code.org Wrap Up video reported as of this writing. So, any thoughts on why the big disconnect, and how close the stats might reflect reality? Code.org does explain that an 'Hour of Code' is not necessarily an 'hour of code' ("Not everybody finishes an Hour of Code tutorial. Some students spend one hour. Some spend 10 minutes. Some spend days. Instead of counting how many students 'finish one hour'; or how much time they spent, this [LOC] is our simplest measure of progress"). So, with millions being spent on efforts to get Code.org into the nation's schools — New York and Chicago have already committed their 1.5 million K-12 students — is it important to get a better understanding of what the Hour of Code usage stats actually represent — and what their limitations might be — and not just accept as gospel reports like AllThingsD's 15 Million Students Learned to Program This Week, Thanks to Hour of Code ("every other school family in the U.S. has a child that has done the Hour of Code")?"

An anonymous reader writes "I'm not a big fan of heat maps, but the US Census Bureau has just released a set of maps that succinctly capture average income distribution across the US. BusinessInsider points out that well over half of the most affluent counties in the US are concentrated in the Northeast (counting Virginia, presumably for the suburbs of Washington, D.C. located in that southern state). Of course, the cost of living is higher in those counties as well. Meanwhile, poor counties tend to be clustered in the southeast and in southwestern states on the Mexican border. There is good news for the northern prarie states, though, particularly North and South Dakota, as they lead in the number of counties with gains in household income over the past five years."
theodp writes "Among the patents granted to Facebook this week by the USPTO is one for Inferring Household Income for Users of a Social Networking System. 'For example,' Facebook explains, 'an assumption might be made about a user that reads CNN.com and nytimes.com every day that the user is in a higher income bracket than another user that only reads TMZ.com and PerezHilton.com on the theory that a user who reads newspapers might be assumed to make more money than a user who only reads celebrity gossip blogs.' Advertisements such as those for travel packages, cars, and home mortgages, Facebook adds, 'are targeted to users based on income bracket,' which might also be inferred by 'gathering and analyzing different types of information about a user's geographic location.' Hey, what could go wrong?"
nk497 writes "Consumer hard drives don't fail any more often than enterprise-grade hardware — despite the price difference. That's according to online storage firm Backblaze, which uses a mix of both types of drive. It studied its own hardware, finding consumer hard-drives had a failure rate of 4.2%, while enterprise-grade drives failed at a rate of 4.6%. CEO Gleb Budman noted: 'It turns out that the consumer drive failure rate does go up after three years, but all three of the first three years are pretty good,' he notes. 'We have no data on enterprise drives older than two years, so we don't know if they will also have an increase in failure rate. It could be that the vaunted reliability of enterprise drives kicks in after two years, but because we haven't seen any of that reliability in the first two years, I'm skeptical.'"
symbolset writes "Zach Whittaker over at ZDNet covers an IDC report. In it the 2013 9.7% forecast decline in PC shipments is advanced to 10.1%. Further, IDC's longer-term forecast turns quite grim: contracting 23% from 2012 levels by 2017. There is also a projection of future Windows tablet sales, and a statement that total Windows tablet sales for 2013 are expected to be 'less than 7.5 million units.'"
An anonymous reader writes "Until now, it was particularly difficult to obtain reliable figures on the results of the Android operating system in China. Indeed, there is no 'centralized app store' and most smartphones sold in the country do not use Google services, including activation. In fact, it is very difficult to know the actual results. The search engine Baidu has corrected this by publishing a report on trends in the mobile internet for the 3rd quarter 2013. It appears that there would be now 270 million active users of the Google platform in the country (more than 20% of the total population). Growth would, however, decrease with a small 13% against 55% for the same period last year but up 10% compared to Q2 2013."
mikejuk writes "Researchers have developed an online dating system that not only matches you with partners you'll find attractive, but who are also likely to find you attractive too. The researchers at the University of Iowa have addressed an underlying problem of online dating sites. There's no doubt that such sites are ever increasing in popularity, and have good algorithms taking into account the reported likes, interests and hobbies of the person looking for a partner to come up with a potential match. What's less well catered for is the trickier aspect of the reciprocal interest – you may think person x looks nice, but will they find you equally attractive? The problem here is that if you are Average Joe and try asking out Supermodels Ann, Barbara and Cheryl, you're unlikely to get a reply. Well, not a printable one, anyway. So coming up with yet another supermodel for you to sob over isn't a lot of help.Instead, the researchers add a note of reality by analyzing the replies you get, and use this to work out how attractive you are. This is a scary thought for many of us, and one we may well not want an honest answer to. The results are used to recommend people who might actually reply if you get in contact with them. Fortunately for the attractively challenged, the research is still just that – research. However, given the fact the online dating market is worth around $3 billion a year, chances are someone is going to make use of this. We have been warned."
Daniel_Stuckey writes "Travel officials expect about 3 million people to venture by plane to their turkey dinner, and already hundreds of flights have been canceled and thousands delayed—including more than a third of routes at the major airport hub in Dallas, which will have a ripple effect down through the airline system as thwarted passengers try to hop on other flights. This inspired flight-tracking site FlightAware to develop an interactive 'Misery Map' visualizing flight statuses in real-time and the megastorm traversing the country simultaneously. Because who doesn't love a little data viz schadenfreude?"
itwbennett writes "According to data from the Bureau of Labor Statistics, in 2012 about 22% of computer programmers, software and web developers in the United States were female. That number comes from the Current Population Survey, which is based on interviews with 60,000 households. But Tracy Chou, an engineer at Pinterest, thinks the number is actually much lower than that. And last month she created a GitHub project to collect data on how many females are employed full-time writing or architecting software. Even at this early point, the data is striking: Based on data reported for 107 companies, 438 of 3,594 engineers (12%) are female. Here's how some well-known companies stack up."
Nerval's Lobster writes "In a previous posting, developer and programmer Jeff Cogswell compared a few C++ compilers on Linux. Now he's going to perform a similar set of tests for Windows. "Like all things Windows, it can get costly doing C++ development in this environment," he writes. "However, there are a couple notable exceptions" such as free and open-source cygwin, mingW, Express Versions of Visual Studio, and Embacadero. He also matched up the Intel C++ Compiler, Microsoft C++ Compiler, and the Embarcadero C++ 6.70 Compiler. He found some interesting things — for example, Intel's compiler is pretty fast, but its annoying habit of occasionally "calling home" to check licensing information kept throwing off the rests. Read on to see how the compilers matched up in his testing."
itwbennett writes "A timely CareerBuilder survey finds that 23% of IT pros spend the holiday with coworkers, either in the office or at another location. But the findings vary widely by city. In Boston, for example, you're pretty sure to be on your own for the holiday — only 6% of coworkers there nosh together. While in Atlanta (35%) or Dallas (30%) things are downright chummy."
theodp writes "The same cast of billionaire characters — Mark Zuckerberg, Bill Gates, Steve Ballmer, Eric Schmidt — is backing FWD.us, which is lobbying Congress for more visas to 'meet our workforce needs,' as well as Code.org, which aims to popularize Computer Science education in the U.S. to address a projected CS job shortfall. In laying out the two-pronged strategy for the Senate, Microsoft General Counsel and Code.org Board member Brad Smith argued that providing more kids with a STEM education — particularly CS — was 'an issue of critical importance to our country.' But with its K-8 learn-to-code program which calls for teachers to receive 25% less money if fewer than 40% of their CS students are girls, Smith's Code.org is sending the message that training too many boys isn't an acceptable solution to the nation's CS crisis. 'When 10 or more students complete the course,' explains Code.org, "you will receive a $750 DonorsChoose.org gift code. If 40% or more of your participating students are female, you'll receive an additional $250, for a total gift of $1,000 in DonorsChoose.org funding!" The $1+ million Code.org-DonorsChoose CS education partnership appears to draw inspiration from a $5 million Google-DoonorsChoose STEM education partnership which includes nebulous conditions that disqualify schools from AP STEM funding if projected participation by female students in AP STEM programs is deemed insufficient. So, are Zuckerberg, Gates, Ballmer, and Schmidt walking-the-gender-diversity-talk at their own companies? Not according to the NY Times, which just reported that women still account for only about 25% of all employees at Code.org supporters Apple, Google, Facebook, and Microsoft. By the way, while not mentioning these specific programs, CNET reports that Slashdot owner Dice supports the STEM efforts of Code.org and Donors Choose."
First time accepted submitter fasuin writes "Which is the most advanced cloud storage solution? Which is the impact of server locations? What are the benefits of advanced techniques to optimise data transfers? Researchers from Italy and The Netherlands have come out with a set of benchmarks that allowed them to compare Dropbox, CloudDrive, SkyDrive and Google Drive. Which is the best? You can check it by yourself by running the tests on your own if you like." What this kind of benchmarking can't well do, though, is predict which of these cloud storage companies are going to be around in five years, which might be at least as an important a factor.
The Raspberry Pi project that we've been fans of for quite a while now has hit a new milestone: Today, they announced that as of the last week in October, the project has sold more than two million boards. Raspberry Pi is anything but alone in the tiny, hackable computer world (all kinds of other options, from Arduino to the x86-based Minnowboard, are out there, and all have their selling points), but the low price, open-source emphasis, and focus on education have all helped the Pi catch on. If yours is one of these 2 million, what are you using it for? (And if you favor some other small system for your own experiments, what factors matter?)
lpress writes "Department of Education officials, led by Under Secretary of Education Martha Kanter, were on our campus last week, soliciting input on The President's College Value and Affordability plan. The discussion focused primarily on the design of a system for rating colleges and to a lesser extent on innovation and improvement. While the feedback was constructive, many attendees pointed out difficulties and limitations of any college rating system. One solution is to open the process by having the Department of Education gather and post data and provide a platform and tools for all interested parties to analyze, visualize and discuss it. Similarly, open innovation should be encouraged, for example, by providing a hosted version of the open source education platform MOOC.ORG."
ananyo writes "The plague of non-reproducibility in science may be mostly due to scientists' use of weak statistical tests, as shown by an innovative method developed by statistician Valen Johnson, at Texas A&M University. Johnson found that a P value of 0.05 or less — commonly considered evidence in support of a hypothesis in many fields including social science — still meant that as many as 17–25% of such findings are probably false (PDF). He advocates for scientists to use more stringent P values of 0.005 or less to support their findings, and thinks that the use of the 0.05 standard might account for most of the problem of non-reproducibility in science — even more than other issues, such as biases and scientific misconduct."
Lemeowski writes "Time has been good to Linux and the kernel community, with the level of participation and volume of activity reaching unprecedented levels. But as core Linux kernel developers grow older, there's a very real concern about ensuring younger generations are getting involved. In this post, Open Access supporter Luis Ibanez shares some exciting stats about recent releases of the Linux kernel, but also warns that 'Maintaining the vitality of this large community does not happen spontaneously. On the contrary, it requires dedication and attention by community members on how to bring new contributors on board, and how to train them and integrate them alongside the well-established developers.'"
MrSeb writes with this excerpt, linking to several pretty graphs: "For more than 30 years, the realm of computing has been intrinsically linked to the humble hard drive. It has been a complex and sometimes torturous relationship, but there's no denying the huge role that hard drives have played in the growth and popularization of PCs, and more recently in the rapid expansion of online and cloud storage. Given our exceedingly heavy reliance on hard drives, it's very, very weird that one piece of vital information still eludes us: How long does a hard drive last? According to some new data, gathered from 25,000 hard drives that have been spinning for four years, it turns out that hard drives actually have a surprisingly low failure rate."
