Submission + - UK Parliament: Banning Tor is Unacceptable and Technologically Impossible (

An anonymous reader writes: Months after UK prime minister David Cameron sought to ban strong encryption, a new parliamentary briefing contradicts that, at least when it comes to Tor. The briefing says that "there is widespread agreement that banning online anonymity systems altogether is not seen as an acceptable policy option in the UK. Even if it were, there would be technical challenges." The briefing cites Tor's ability to circumvent such censorship in countries like China as well as looking at both legal and illegal uses of Tor.

Kali Linux On a Raspberry Pi (A/B+/2) With LUKS Disk Encryption 37

An anonymous reader writes With the advent of smaller, faster ARM hardware such as the new Raspberry Pi 2 (which now has a Kali image built for it), we've been seeing more and more use of these small devices as 'throw-away computers'. While this might be a new and novel technology, there's one major drawback to this concept – and that is the confidentiality of the data stored on the device itself. Most of the setups do little to protect the sensitive information saved on the SD cards of these little computers.

Submission + - Intel Announces Xeon D SoC Line Based On Broadwell Core Architecture (

MojoKid writes: Intel is targeting big core performance and intelligence in a microserver form factor with its new Xeon D family of processors, the company's first ever Xeon-based System-on-Chip (SoC) design. The Xeon D line Intel is announcing today is built on their 14nm process technology and combines the performance and features of its traditional Xeon chips with the size and power savings of an SoC. According to Intel, Xeon D delivers up to 3.4x faster performance node and up to 1.7x better performance per watt compared to the company's Atom C2750. The Xeon D is the third generation of the family and it's actually based on Intel's Broadwell architecture. Intel unveiled two new Xeon D processors today, the D-1540 (8 cores, 16 threads, 2GHz, 45W TDP) and D-1520 (4 cores, 8 threads, 2.2GHz, 45W TDP). These chips have memory controllers capable of addressing up to 128GB. They also feature an integrated platform controller hub (PCH), integrated I/Os, and two integrated 10 Gigabit Ethernet ports. Again, all of this is based on Intel's Broadwell core CPU architecture, so performance per watt should be strong.

Submission + - Hard-coded root password found in Synology DiskStation Manager VPN module (

hypnosec writes: Synology DiskStation Manager has a critical vulnerability wherein VPN module has a hard-coded password for root, which attackers can use to connect to Synology device and possibly other devices on the shared network. The hard-coded root password is ‘synopass’. Users will not be able to logon to the web interface of the device using the root:synopass combination; however, “when enabling the VPN server, root:synopass will get you authenticated and connected!”

Submission + - Feds Seek Prison for Man Who Taught How to Beat a Polygraph

George Maschke writes: In a case with serious First Amendment implications, McClatchy reports that federal prosecutors are seeking a prison sentence for Chad Dixon of Indiana, who committed the crime of teaching people how to pass or beat a lie detector test. Some of his students passed polygraphs and went on to be hired by federal agencies. A pleading filed by prosecutors all but admits that polygraph tests can be beaten. The feds have also raided and seized business records from Doug Williams, who has taught many more people how to pass or beat a polygraph over the past 30 years. Williams has not been criminally charged.

I'm a co-founder of (we suggest using Tor to access the site) a non-profit, public interest website dedicated to exposing and ending waste, fraud, and abuse associated with the use of lie detectors. We offer a free e-book, The Lie Behind the Lie Detector (1 mb PDF) that explains how to pass a polygraph (whether or not one is telling the truth). We make this information available not to help liars beat the system, but to provide truthful people with a means of protecting themselves against the high risk of a false positive outcome. As McClatchy reported last week, I received suspicious e-mails earlier this year that seemed like an attempted entrapment.

Rather than trying to criminalize teaching people how to pass a polygraph, isn't it time our government re-evaluated its reliance on the pseudoscience of polygraphy?

Submission + - 3D printers shown to emit potentially harmful nanosized particles (

An anonymous reader writes: A new study by researchers in the Built Environment Research Group at the Illinois Institute of Technology shows that commercially available desktop 3D printers can have substantial emissions of potentially harmful nanosized particles in indoor air. Many desktop 3D printers rely on a process where a thermoplastic feedstock is heated, extruded through a small nozzle, and deposited onto a surface to build 3D objects. Similar processes have been shown to have significant aerosol emissions in other studies using a range of plastic feedstocks, but mostly in industrial environments. In this study, researchers measured ultrafine particle concentrations resulting from a popular commercially available desktop 3D printer using two different plastic feedstocks inside an office. Ultrafine particles (or UFPs) are small, nanosized particles less than 100 nanometers in diameter. Inhalation of UFPs may be important from a health perspective because they deposit efficiently in the lung and can even translocate to the brain. Estimates of emission rates of total UFPs in this study were high, ranging from about 20 billion particles per minute for a 3D printer utilizing a lower temperature polylactic acid (PLA) feedstock to about 200 billion particles per minute for the same type of 3D printer utilizing a higher temperature acrylonitrile butadiene styrene (ABS) feedstock. The emission rates were similar to those measured in previous studies of several other devices and indoor activities, including cooking on a gas or electric stove, burning scented candles, operating laser printers, or even burning a cigarette.

Submission + - Some 13 years after the DeCSS case, Congressional IT endorses VLC (

robp writes: After a link to VLC showed up in one of HBO's DMCA takedown requests, I recalled how often I've linked to VLC in my own copy, and how often I've seen that app noted across traditional-media outlets--even though you could make the same arguments against linking to it that Judge Kaplan bought in 2000. Now, though, even the House's own IT department not only links to this CSS-circumventing app but endorses it. Question is, what led to this enlightenment?

Home Automation Kit Includes Arduino, RasPi Dev Boards 49

DeviceGuru writes "WigWag has developed a home automation kit that combines a Linux-based 6LoWPAN router with sensor units running the open-source Contiki IoT (Internet of Things) OS. Users can add ZigBee, Bluetooth, and other modules to expand the home network, and the WigWam development kit provides shield development boards for use with Arduino and Raspberry Pi SBCs. Users control the devices with a smartphone app (initially Android-based) and associated WigWag cloud service, which lets the devices remotely respond to sensor-based events such as motion detection, rain, noise, etc. Developers can create rules-based scripts for controlling devices using WigWag's open-source Javascript-based DeviceJS development environment. WigWag used a Kickstarter page to fund production and has already tripled its goal."

Ask Slashdot: What Is the Most Painless Intro To GPU Programming? 198

dryriver writes "I am an intermediate-level programmer who works mostly in C# NET. I have a couple of image/video processing algorithms that are highly parallelizable — running them on a GPU instead of a CPU should result in a considerable speedup (anywhere from 10x times to perhaps 30x or 40x times speedup, depending on the quality of the implementation). Now here is my question: What, currently, is the most painless way to start playing with GPU programming? Do I have to learn CUDA/OpenCL — which seems a daunting task to me — or is there a simpler way? Perhaps a Visual Programming Language or 'VPL' that lets you connect boxes/nodes and access the GPU very simply? I should mention that I am on Windows, and that the GPU computing prototypes I want to build should be able to run on Windows. Surely there must a be a 'relatively painless' way out there, with which one can begin to learn how to harness the GPU?"

Yahoo Censors Tumblr Porn 216

coolnumbr12 writes "When Yahoo purchased Tumblr in May, Tumblr founder David Karp said Tumblr wouldn't be changing, and Yahoo CEO Marissa Mayer said, 'Part of our strategy here is to let Tumblr be Tumblr.' But a new search policy went into effect Thursday that excludes all adult blogs from Google, Bing, Yahoo and other search engines by disabling indexing of anything it tags as 'adult.' The policy effectively makes the content and 10 percent of Tumblr users completely invisible."

J.K. Rowling Should Try the Voting Algorithm 128

Frequent contributor Bennett Haselton proposes a new use for online, anonymous voting: helping sort skill from luck in the cheek-by-jowl world of best-selling (and would-be best-selling) authors: "J.K. Rowling recently confirmed that she was the author of a book she had published under a pseudonym, which spiked in sales after she was outed as the true author. Perhaps she was doing an experiment to see how much luck had played a role in propelling her to worldwide success, and whether she could recreate anything close to that success when starting from scratch. But a better way to answer that question would be to strike a deal with an amateur-fiction-hosting site and use the random-sample-voting algorithm that I've written so much about, to test how her writing stacks up against other writers in the same genre." Read on for more. Update: 07/20 01:23 GMT by T : Note: An editorial goof (mine) swapped out the word "confirmed" for "revealed" (above) in an earlier rendering of this story.

Submission + - Alpha Centauri Bb Given a Name ( 1

SchrodingerZ writes: The nearest planet outside our solar system has recently been named Albertus Alauda. Originally named Alpha Centauri Bb, the planet is the closest known planet not orbiting the Sun, being a mere 4.3 light years away. The name comes from Jay Lark, who won the naming contest held by Uwingu starting last month and ending on April 22. Lark remarks that the name comes from the Latin name of his late grandfather, stating, "My grandfather passed away after a lengthy and valiant battle with cancer; his name in Latin means noble or bright and to praise or extol." The competition for naming the planet came from Uwing, a company which used the buying of name proposals and votes to fund grants for future space exploration ventures. Albertus Alauda won the competition with 751 votes, followed by Rakhat with 684 votes, and Caleo, with 622 votes.
