Yahoo releases massive 13.5TB web-browsing data set to researchers

Yahoo’s business may be struggling , but millions of people still visit its site to read the news every day. That gives the company unique insights into browsing and reading habits, and today the company has released a huge swath of that data. The “Yahoo News Feed dataset” incorporates anonymous browsing habits of 20 million users between February and May of 2015 across a variety of Yahoo properties, including its home page, main news site, Yahoo Sports, Yahoo Finance, Yahoo Movies and Yahoo Real Estate. All told, the data set is a whopping 13.5TB and covers 110 billion unique interaction “events.” Yahoo calls it the “largest machine learning dataset” ever publicly released, and we’re inclined to believe them — there aren’t very many companies who could accumulate this much browsing data. It’s a huge amount of data, but fortunately you don’t need to worry about advertisers mining it to make more targeted ads. Yahoo is specifically releasing it only to the academic research community to help people build more effective recommendation algorithms. As noted by the MIT Technology Review , the data set includes includes headlines that Yahoo’s personalization algorithms show to visitors, a summary of the article, and which specific articles people click. There’s also some demographic data for about 7 million users that includes age, gender and location — but it’s all been anonymized. Improving recommendation algorithms is particularly relevant right now, as some of the biggest web properties rely on good recommendation engines to engage with their user. Netflix, Amazon, Google, Apple and Facebook (just to name a few) all rely on serving their users relevant recommendations to keep them engaged with their products and services. Yes, it’s a way for those companies to make more money, but it also generally makes for a better user experience — as long as those recommendations are good. Yahoo’s huge data release will probably go a long way towards meeting that goal. [Image credit: Noah Berger/Bloomberg via Getty Images] Source: Yahoo (Businesswire)

Graphene Flakes Facilitate Neuromorphic Chips

An anonymous reader writes: One of the hot areas of semiconductor research right now is the creation of so-called neuromorphic chips — processors whose transistors are networked in such a way to imitate how neurons interact. “One way of building such transistors is to construct them of lasers that rely on an encoding approach called “spiking.” Depending on the input, the laser will either provide a brief spike in its output of photons or not respond at all. Instead of using the on or off state of the transistor to represent the 1s and 0s of digital data, these neural transistors rely on the time intervals between spikes.” Now, research published in Nature Scientific Reports has shown how to stabilize these laser spikes, so that they’re responsive at picosecond intervals. “The team achieved this by placing a tiny piece of graphene inside a semiconductor laser. The graphene acts as a ‘saturable absorber, ‘ soaking up photons and then emitting them in a quick burst. Graphene, it turns out, makes a good saturable absorber because it can take up and release a lot of photons extremely fast, and it works at any wavelength; so lasers emitting different colors could be used simultaneously, without interfering with each other—speeding processing.” Read more of this story at Slashdot.

Archaeologists have new tools that make it easy to scan artifacts

A European Union-funded project called ” Presious ” could make a modern Indiana Jones’ tasks easier even if they’re operating with tiny budgets. See, the initiative is currently developing a number of software tools they can use to scan artifacts. The first one can be used to scan stone objects and estimate their erosion patterns, while the second one treats scanned fragments like 3D puzzles and pieces them together. Finally, the third tool can fill in gaps in symmetrical objects if some of their pieces couldn’t be found. According to the European Union , these tools’ capabilities are made possible by the development of predictive scanning. That technique taps into existing repositories of digitized archaeological finds to predict erosion patterns, missing pieces’ shapes and broken fragments’ fits. The best thing about these tools is that archaeologists will be able to download them for free once development is done this January 2016. Via: Popsci Source: Presious

BBC Confirms 50% Bitrate Savings For H.265/HEVC Vs H.264/AVC

An anonymous reader writes: A research team from the BBC has done a series of tests to confirm earlier computations showing a ~50% savings in bit rate for H.265/HEVC compared to video using H.264/AVC at comparable quality. “The subjective tests used a carefully selected set of coded video sequences at four different picture sizes: UHD (3840×2160 and 4096×2048), 1080p (1920×1080), 720p (1280×720) and 480p (832×480), at frame rates of 30Hz, 50Hz, or 60Hz. The video content was chosen to represent diverse spatial and temporal characteristics, and then coded using HEVC and AVC standards at a wide span of bit rates producing a variety of quality levels.” Here is the full published analysis. “The tests confirmed the significant compression efficiency improvements achieved in HEVC, verifying the results previously reported using objective quality metrics (PSNR based methods).” The team did not test against VP9, which is shaping up to be an impressive standard as well.

T-Mobile’s CEO does damage control, apologizes to the EFF

T-Mobile CEO John Legere has published an open letter on the company’s website, and it smells like an attempt at damage control after getting some real backlash. As you might know, he’s been making good use of his colorful vocabulary to defend his company over accusations that it’s throttling YouTube videos these past few weeks. In the process, he lambasted Google and accused the Electronic Frontier Foundation of being a paid mouthpiece. In the surprisingly expletive-free missive, he claims that Binge On is a “VERY ‘pro’ net neutrality capability, ” because you can switch it on or off whenever you want. The T-Mobile uncarrier feature allows you to stream 480p videos without eating up your data, but it can only do so for specific services like Netflix. That doesn’t sit well with net neutrality advocates who believe that it makes certain apps more appealing than others. The FCC cited that as one of its reasons when it summoned the company to talk about its data exemption scheme in December. Legere also apologizes to the EFF for posting a video asking “who the fuck” the organization is and who’s paying it. His response was triggered by the non-profit digital rights group’s question on Twitter, asking if Binge On alters the video stream in any way or limits its bandwidth: Look, by now you know that I am a vocal, animated and sometimes foul mouthed CEO. I don’t filter myself and you know that no one at T-Mobile filters me either (no, they don’t even try). That means I will sometimes incite a bit of a ‘social media riot’, but I’m not going to apologize for that. I will however apologize for offending EFF and its supporters. Just because we don’t completely agree on all aspects of Binge On doesn’t mean I don’t see how they fight for consumers. We both agree that it is important to protect consumers’ rights and to give consumers value. We have that in common, so more power to them. As I mentioned last week, we look forward to sitting down and talking with the EFF and that is a step we will definitely take. While we may never know why the CEO suddenly decided to publish this letter, he said he decided to write it up for the sake of the data exemption feature: Unfortunately, my color commentary from last week is now drowning out the real value of Binge On – so hopefully this letter will help make that clear again. . @EFF pic.twitter.com/pv6V4oOJwS — John Legere (@JohnLegere) January 7, 2016 T-Mobile’s CEO is dying to know who EFF is. Friends, please tweet at @JohnLegere with the hashtag #WeAreEFF to enlighten him. — EFF (@EFF) January 7, 2016 [Image credit: Patrick T. Fallon/Bloomberg via Getty Images] Source: T-Mobile

Scientists find a way to make concrete on Mars

If humans are ever going to have a long-term presence on Mars , they’ll need to make their own buildings — they can’t count on timely shipments from Earth. But how do they do that when the resources they have will share little in common with what they knew back home? Northwestern University researchers have an idea. They’ve developed a concrete that uses Mars’ native materials. You only have to heat sulphur until it melts, mix it with an equal part of Martian soil and let it cool. The finished concrete is very strong, easy to work with and recyclable — you just have to reheat it to get some building supplies back. Any need for Martian concrete is years away at best , but the discovery is still crucial. It suggests that explorers won’t have much trouble transitioning from short-term shelters to more permanent structures. Also, any would-be settlers can afford to pack light. Rather than carry every possible building they might want, they could bring just the essentials and build more once they’re established on the Red Planet’s surface.

OCZ RevoDrive 400 NVMe SSD Unveiled With Nearly 2.7GB/Sec Tested Throughput

MojoKid writes: Solid State Drive technology continues to make strides in performance, reliability and cost. At the CES 2016 show there were a number of storage manufacturers on hand showing off their latest grear, though not many made quite the splash that Toshiba’s OCZ Technology group made with the annoucement of their new RevoDrive 400 NVMe PCI Express SSD. OCZ is tapping on Toshiba’s NVMe controller technology to deliver serious bandwidth in this consumer-targeted M.2 gumstick style drive that also comes with a X4 PCI Express card adapater. The drive boasts specs conservatively at 2.4GB/sec for reads and 1.6GB/sec for writes in peak sequential transfer bandwidth. IOPs are rated at 210K and 140K for writes respectively. In the demo ATTO test they were running, the RevoDrive 400 actually peaks at 2.69GB/sec for reads and also hits every bit of that 1.6GB/sec write spec for large sequential transfers.

How We Know North Korea Didn’t Detonate a Hydrogen Bomb

StartsWithABang writes: The news has been aflame with reports that North Korea detonated a hydrogen bomb on January 6th, greatly expanding its nuclear capabilities with their fourth nuclear test and the potential to carry out a devastating strike against either South Korea or, if they’re more ambitious, the United States. The physics of what a nuclear explosion actually does and how that signal propagates through the air, oceans and ground, however, can tell us whether this was truly a nuclear detonation at all, and if so, whether it was fusion or fission. From all the data we’ve collected, this appears to be nothing new: just a run-of-the-mill fission bomb, with the rest being a sensationalized claim. (Related: Yesterday’s post about how seismic data also points to a conventional nuke, rather than an H-bomb.) Read more of this story at Slashdot.
