Submission + - SPAM: Learning to Program is Getting Harder

theodp writes: While Google suggests that parents and educators are to blame for why kids can't code, Allen Downey argues that learning to program is getting harder. Downey writes: "The fundamental problem is that the barrier between using a computer and programming a computer is getting higher. When I got a Commodore 64 (in 1982, I think) this barrier was non-existent. When you turned on the computer, it loaded and ran a software development environment (SDE). In order to do anything, you had to type at least one line of code, even if all it did was another program (like Archon). Since then, three changes have made it incrementally harder for users to become programmers: 1) Computer retailers stopped installing development environments by default. As a result, anyone learning to program has to start by installing an SDE — and that's a bigger barrier than you might expect. Many users have never installed anything, don't know how to, or might not be allowed to. Installing software is easier now than it used to be, but it is still error prone and can be frustrating. If someone just wants to learn to program, they shouldn't have to learn system administration first. 2) User interfaces shifted from command-line interfaces (CLIs) to graphical user interfaces (GUIs). GUIs are generally easier to use, but they hide information from users about what's really happening. When users really don't need to know, hiding information can be a good thing. The problem is that GUIs hide a lot of information programmers need to know. So when a user decides to become a programmer, they are suddenly confronted with all the information that's been hidden from them. If someone just wants to learn to program, they shouldn't have to learn operating system concepts first. 3) Cloud computing has taken information hiding to a whole new level. People using web applications often have only a vague idea of where their data is stored and what applications they can use to access it. Many users, especially on mobile devices, don't distinguish between operating systems, applications, web browsers, and web applications. When they upload and download data, they are often confused about where is it coming from and where it is going. When they install something, they are often confused about what is being installed where. For someone who grew up with a Commodore 64, learning to program was hard enough. For someone growing up with a cloud-connected mobile device, it is much harder." So, with the Feds budgeting $200 million a year for K-12 CS at the behest of U.S. tech leaders, can't the tech giants at least put a BASIC on every phone/tablet/laptop for kids?

Submission + - Ask Slashdot: Best Strategies For Teaching Kids CS Skills? (discorunner.com)

beaverdownunder writes: We're currently working on developing a teaching platform based around our BASIC interpreter DiscoRunner, and we would love to hear from Slashdot readers as to what methods they've used in the past to teach kids computer science concepts — which worked, what didn't, and why.

This will obviously be invaluable to us when it comes to working out the lessons that will be taught in our fight-to-save-the-world-from-evil learning environment, and we would be eternally grateful for any scraps of wisdom you could toss our way. =)

Thank you!

Submission + - Virtual reality experiment wants to put white people in black bodies (dailydot.com)

Molly McHugh writes: It's as simple as making a light-skinned person feel connected to a virtual, darker skinned self—a thought experiment pretty much impossible without the immersive potency of VR. The effect is achieved by outfitting participants in VR headsets with built-in head-tracking and motion capture capabilities that sync actual movement to virtual experience.

Submission + - We Don't Need No Stinkin' 4K, LG Says Its Bringing 8K Love (hothardware.com)

MojoKid writes: One of the most in-your-face buzzwords of the past year has been "4K," and there's little doubt that the forthcoming CES show in early January will bring it back in full force. As it stands today, 4K really isn't that rare, or expensive. You can even get 4K PC monitors for an attractive price. There does remain one issue, however; a lack of 4K content. We're beginning to see things improve, but it's still slow going. Given that, you might imagine that display vendors would hold off on trying to push that resolution envelope further – but you just can't stop hardware vendors from pushing the envelope. Earlier this year, both Apple and Dell unveiled "5K" displays that nearly doubled the number of pixels of 4K displays. 4K already brutalizes top-end graphics cards and lacks widely available video content, and yet here we are looking at the prospect of 5K. Many jaws dropped when 4K was first announced, and likewise with 5K. Now? Well, yes, 8K is on its way. We have LG to thank for that. At CES, the company will be showing-off a 55-inch display that boasts a staggering 33 million pixels — derived from a resolution of 7680x4320. It might not be immediately clear, but that's far more pixels than 4K, which suggests this whole "K" system of measuring resolutions is a little odd. On paper, you might imagine that 8K has twice the pixels of 4K, but instead, it's 4x.

Comment QR code (Score 1) 2

I can suggest using QR codes or something like that, that the person must use and put in some place visible, so a camera can parse the QR code (instead of "parsing" a face) and identify the person. I think there is no much waste of time, just a second for the person to stand still so the camera can parse the QR code.

Submission + - Kim Dotcom declares he is 'broke' because of legal fight

mrspoonsi writes: Kim Dotcom, the founder of the seized file-sharing site Megaupload, has declared himself "broke". The entrepreneur said he had spent $10m (£6.4m) on legal costs since being arrested in New Zealand in 2012 and accused of internet piracy. Mr Dotcom had employed a local law firm to fight the US's attempt to extradite him, but his defence team stepped down a fortnight ago without explaining why. Mr Dotcom said he would now represent himself at a bail hearing on Thursday. He denies charges of racketeering, conspiring to commit copyright infringement and money laundering. He told a conference in London, via a video link, that his lawyers had resigned because he had run out of money. "The [US authorities] have certainly managed to drain my resources and dehydrate me, and without lawyers I am defenceless," he said. "They used that opportunity to try and get my bail revoked and that's what I'm facing."

Submission + - Ask Slashdot: How to make a gaming PC 'wife friendly' for living room use. 3

shadeshope writes: Having just gotten married I find that for some inexplicable reason my wife doesn't like my huge, noisy, 'ugly' gaming pc being the living room. I have tried hiding it in a tv cabinet, still too noisy. I have placed in in another room and run hdmi and usb cables but the propagation delay caused horrible tearing and lag when playing games. Have any other slash dotters encountered this problem? I don't want to buy a console(steam sales let me game so cheaply), or mess with water cooling. Ideally I would just hide it in the attic, is there some wireless technology that would be fast enough for gaming use? I have become quite attached to 'behemoth'. I have been upgrading him for years and he is the centre of my digital life. I run plex home theatre, media centre, steam, iTunes and air server. Will I have to do my gaming in the spare room? Once I have sorted this small problem going to try and make a case for the efficacy of a projector to replace the television..... it takes up less space, motorised screen could be hidden when not in use etc.

Submission + - Ask Slashdot: Biometric Authentcation 2

kwelch007 writes: I run a network for a company that does manufacturing primarily in a clean-room. We have many systems in place that track countless aspects of every step. However, we do not have systems in place to identify the specific user performing the step. I could do this easily, but asking users to input their AD login every time they perform a task is a time-waster (we have "shared" workstations throughout.) My question is, what technologies are people actually using successfully for said rapid authentication? I've thought about fingerprint scanners, but they don't work because in the CR we have to wear gloves. So, I'm thinking either face-recognition or retinal scans...but am open to other ideas if they are commercially viable. Ideas?

Submission + - Windows Kernel Version Bumped to 10.0

jones_supa writes: In Windows, the kernel version number is once again in sync with the product version. Build 9888 of Windows 10 Technical Preview is making the rounds in a private channel and the kernel version has indeed been bumped from 6.4 to 10.0. Version 6.x has been in use since Windows Vista. Neowin speculates that this large jump in version number is likely related to the massive overhaul of the underlying components of the OS to make it the core for all of Microsoft's products. The company is working to consolidate all of its platforms into what the company calls OneCore, which, as the name implies, will be the one core for all of the company's operating systems. We will be curious to see if this causes any software comparability issues with legacy applications.

Submission + - CERN Releases LHC Data (symmetrymagazine.org)

An anonymous reader writes: Ever wished you had access to CERN's LHC data to help with your backyard particle collision research? Today you're in luck. CERN has launched its Open Data Portal, which makes experimental data produced by the Large Hadron Collider open to the public. "The first high-level and analyzable collision data openly released come from the CMS experiment and were originally collected in 2010 during the first LHC run. This data set is now publicly available on the CERN Open Data Portal. Open source software to read and analyze the data is also available, together with the corresponding documentation. The CMS collaboration is committed to releasing its data three years after collection, after they have been thoroughly studied by the collaboration."

Submission + - Coal Plants Get New Lease on Life with Natural Gas

HughPickens.com writes: Christina Nunez reports in National Geographic that in the past four years, at least 29 coal-fired plants in 10 states have switched to natural gas or biomass while another 54 units, mostly in the US Northeast and Midwest, are slated to be converted over the next nine years. By switching to natural gas, plant operators can take advantage of a relatively cheap and plentiful US supply. The change can also help them meet proposed federal rules to limit heat-trapping carbon dioxide emissions from power plants, given that electricity generation from natural gas emits about half as much carbon as electricity from coal does.

But not everyone is happy with the conversions. The Dunkirk plant in western New York, slated for conversion to natural gas, is the focus of a lawsuit by environmental groups that say the $150 million repowering will force the state's energy consumers to pay for an unnecessary facility. "What we're concerned about is that the Dunkirk proceeding is setting a really, really bad precedent where we're going to keep these old, outdated, polluting plants on life support for political reasons," says Christopher Amato. Dunkirk's operator, NRG, wanted to mothball the plant in 2012, saying it was not economical to run. The utility, National Grid, said shutting it down could make local power supplies less reliable, a problem that could be fixed by boosting transmission capacity—at a lower cost than repowering Dunkirk. Meanwhile the citizens of Dunkirk are happy the plant is staying open. “We couldn’t let it happen. We would lose our tax base, we would lose our jobs, we would lose our future,” said State Sen. Catharine M. Young. “This agreement saves us. It gives us a foundation on which to build our economy. It gives us hope. This is our community’s Christmas miracle!”
