Submission + - Maps Suggest Marco Polo May Have "Discovered" America 1

An anonymous reader writes: For a guy who claimed to spend 17 years in China as a confidant of Kublai Khan, Marco Polo left a surprisingly skimpy paper trail. No Asian sources mention the footloose Italian. The only record of his 13th-century odyssey through the Far East is the hot air of his own Travels, which was actually an “as told to” penned by a writer of romances. But a set of 14 parchments, now collected and exhaustively studied for the first time, give us a raft of new stories about Polo’s journeys and something notably missing from his own account: maps. If genuine, the maps would show that Polo recorded the shape of the Alaskan coast—and the strait separating it from Asia—four centuries before Vitus Bering, the Danish explorer long considered the first European to do so. Perhaps more important, they suggest Polo was aware of the New World two centuries before Columbus.

There's a real dearth of quality submissions lately. Your work is being accepted because the editors need it. Badly. That's why Hugh Pickens keeps getting front paged too, even though he clearly engages in self-promotion. His choice of material is good and write ups concise.

Slashdot needs a new policy and system to foster community contribution. I don't think the site is dead. But I do think editors should consider how to rebuild audience share by transitioning focus away from link aggregation - a market they've lost to Reddit - to content creation. Too many submissions are easily found on Reddit hours before they go live here. That's a bad sign. Fresh content doesn't have that problem.

Submission + - Why the FCC will probably ignore the public on network neutrality (vox.com) 1

walterbyrd writes: The rulemaking process does not function like a popular democracy. In other words, you can't expect that the comment you submit opposing a particular regulation will function like a vote. Rulemaking is more akin to a court proceeding. Changes require systematic, reliable evidence, not emotional expressions . . .

In the wake of more than 3 million comments in the present open Internet proceeding-which at first blush appear overwhelmingly in favor of network neutrality-the current Commission is poised to make history in two ways: its decision on net neutrality, and its acknowledgment of public perspectives. It can continue to shrink the comments of ordinary Americans to a summary count and thank-you for their participation. Or, it can opt for a different path.

Submission + - Is Apple throttling Nvidia GT750M on Macbook Pro ? (wordpress.com)

erodep writes: Nvidia blogs have claimed that the Macbook Pro makes a great CUDA development platform ( http://blogs.nvidia.com/blog/2... ). However it appears that Apple is throttling the performance of the Nvidia GT 750M discrete card with regard to double precision floating point (DPFP) operations which is a basic requirement for CUDA based scientific computing returning a paltry 27 GFLOPS while the host Core i7 does much better at 120 GFLOPS. See http://bit.ly/1vDxUbZ for details. What do Slashdot readers recommend for a portable CUDA development platform for scientific computing ?

Submission + - An Appetite for Wonder: The Makings of a Scientist, by Richard Dawkins (newrepublic.com)

An anonymous reader writes: John Gray, emeritus professor of European thought at the London School of Economics, and a fellow atheist, reviews Richard Dawkins' memoir in the New Republic, writing: "There cannot be much doubt that Dawkins sees himself as a Darwin-like figure, propagating the revelation that came to the Victorian naturalist. ... Dawkins may not be Victorian, but the figure who emerges from An Appetite for Wonder is in many ways decidedly old-fashioned. ... Dawkins’s description of growing up in British colonial Africa, going on to boarding school and then to Oxford, has a similarly archaic flavor and could easily have been written before World War II. ... Born in 1941 in Nairobi, Kenya, and growing up in Nyasaland, now Malawi, Dawkins writes of life in the colonies in glowingly idyllic terms: “We always had a cook, a gardener and several other servants.... Tea was served on the lawn, with beautiful silver teapot and hot-water jug, and a milk jug under a dainty muslin cover ...” ... Exactly how Dawkins became the anti-religious missionary with whom we are familiar will probably never be known. From what he writes here, I doubt he knows himself. ... curiously his teenage passion for Elvis Presley reinforced his vestigial Christianity. Listening to Elvis sing “I Believe,” Dawkins was amazed to discover that the rock star was religious. “I worshipped Elvis,” he recalls, “and I was a strong believer in a non-denominational creator god.” ... We must await the second volume of his memoirs to discover how Dawkins envisions his future. But near the end of the present volume, an inadvertent remark hints at what he might want for himself. Darwin was “never Sir Charles,” he writes, “and what an amazing indictment of our honours system that is.” It is hard to resist the thought that the public recognition that in Britain is conferred by a knighthood is Dawkins’s secret dream. ... What could be more fitting for this tireless evangelist than to become the country’s officially appointed atheist, seated alongside the bishops in the House of Lords? "

Submission + - How Computer Vision Algorithms Cope With Detecting Human Figures In Cubist Art

KentuckyFC writes: The human visual system has evolved to recognise people in almost any pose under a vast range of lighting conditions. But abstract art pushes this ability to its limits by distorting the human form. In particular, Cubism seeks to represent three-dimensional objects on a two-dimensional plane by juxtaposing snapshots from different angles. The result is that a Cubist picture contains many ‘fragments of perception’ of the same object. That's why it is often hard for people to recognise the human figures that these pictures contain. Now a group of computer scientists have tested how computer vision algorithms fare at the task of spotting human figures in Cubist art. They compared a variety of different algorithms against humans in trying to spot human figures in 218 Cubist paintings by Picasso. Humans easily outperform all the algorithms at this task. But some algorithms were much better than others. The most successful were based on so-called "deformable parts models" that recognise human figures by looking for body parts rather than the entire form. Interestingly, the team says this backs up various studies by neuroscientists suggesting that the human brain works in a similar way.

Comment Re:wait for a few more gens of Oculus Rift (Score 4, Interesting) 56

Carmack's keynote at the 2014 Oculus Connect conference said it would take several more generations before Samsung would have panels that could support seamless 120 fps. Apparently there's a problem with peripheral vision noticing 60fps with a significant number of people. Basically, Samsung is focused on developing panels for the phone market and Oculus piggypacks on that development line. They don't have the market penetration to drive display research.

The most interesting part of his discussion was proposing interlaced formats and variable refresh rates with G-sync to up the perceived refresh rate around peripheral vision.

The talk is about 90 minutes and - ironically - audio is not synced with video. Still, he doesn't talk much bullshit and it's an interesting listen.

Comment Skeptical of seamless images / Ars Project (Score 1) 56

I wonder how the group plans to stitch together multiple displays seamlessly. Removing the bezel is only part of the problem. There'd still be a noticeable seam between panels, never mind the problem of lining up pixels. I suppose one could argue that beyond a certain pixel density - +400dpi or something - lining up pixels exactly wouldn't be necessary. But then you'd have to offset by that difference, and the joined panel would have to test for and respond to that offset to compensate.

I think most would be rightly skeptical of this until seeing the tech work first hand.

On another subject, at the Techspot article there was a link to the Ars project. It's some kind of hot swappable modular phone in development.

According to that, you can't swap out CPU or display live but just about everything else would be hot swappable. It's got a nifty photo showing parts to some kind of mock up or beta device.

All I could think of when looking at this was Stringer Bell from The Wire swapping out sim cards in his phone and what a boon that might be for criminals. Or at least crime drama on TV.

Submission + - Fortune.com: Blame Tech Diversity On Culture, not Pipeline (fortune.com)

FrnkMit writes: Challenging a previous Code.org story on tech diversity, a Forbes.com writer interviewed 716 women who left the technology field. Her conclusion: corporate culture, and the larger social structure, is the primary cause they shook the sand of the tech industry from their shoes, never looking back. Specific issues include a lack of maternity policies in small companies, low pay which barely covers day care, "jokes" from male coworkers, and always feeling like the "odd duck". In reality, there are probably many intertwined causes: peer pressure at the high-school and college level, female-unfriendly geek culture, low pay, a lack of accommodations for pregnant/nursing mothers, the myth of "having it all", stereotype threat, and repeated assertions that women aren't biologically suited to writing software and therefore there's no problem at all.

He said the buildings that house the trans-oceanic data cables were designed from the ground up with small rooms, broom closet sized, that the primary data cables run through. ... He said that all data traffic entering those rooms left them with a noticable amount of latency (at the time, late 80s he said it was about 10ms), but no hops. He claimed that the federal government had been monitoring internet activity in these data hubs since the dawn of the web.

Mark Klein, former tech from AT&T, claimed to have witnessed installation of one such room at a San Francisco POP in 2002. He gave a formal statement to attorneys at the Electronic Frontier Foundation, which was printed in this Wired Article. The money quote is below:

While doing my job, I learned that fiber optic cables from the secret room were tapping into the Worldnet circuits by splitting off a portion of the light signal. I saw this in a design document available to me, entitled "Study Group 3, LGX/Splitter Wiring, San Francisco" dated Dec. 10, 2002. I also saw design documents dated Jan. 13, 2004 and Jan. 24, 2003, which instructed technicians on connecting some of the already in-service circuits to the "splitter" cabinet, which diverts some of the light signal to the secret room. The circuits listed were the Peering Links, which connect Worldnet with other networks and hence the whole country, as well as the rest of the world.

One of the documents listed the equipment installed in the secret room, and this list included a Narus STA 6400, which is a "Semantic Traffic Analyzer". The Narus STA technology is known to be used particularly by government intelligence agencies because of its ability to sift through large amounts of data looking for preprogrammed targets. The company's advertising boasts that its technology "captures comprehensive customer usage data ... and transforms it into actionable information.... (It) provides complete visibility for all internet applications.

EFF proceeded to file a lawsuit (Hepting v. AT&T) claiming infringement of privacy by the firm. Though no finding of fact was challenged, ultimately it was dismissed due to retroactive FISA legislation signed by Bush legalizing the process. On appeal, the Supreme Court refused to review the case.

Though many argued that Klein was just one person with a grudge against his employer, and thus dismissed his testimony as overblown or vindictive, in 2013 Edward Snowden's revelations "proved what he'd said was true. That the government did work with network service providers - including AT&T - to install monitoring systems throughout the Internet backbone.

 

Submission + - James Bamford Releases DOJ Report on NSA Warrantless Wiretapping from 1976 (documentcloud.org)

maynard writes: Investigative Journalist James Bamford knows a thing or two more than most about the National Security Agency. Across his more than three-decade long career digging muck out of exactly those places US government intelligence agencies prefered he wouldn't tread, he's published five books and over eighty press reports. Which at times made for some tense confrontations with intelligence officials from an organization once so secret even few members of congress knew of its existence.

For the last several years public focus on the NSA has been on Bush and Obama era reports of illicit domestic spying. From allegations of warrantless wiretapping reported by James Risen in 2005 to secret documents released to journalists at The Guardian by Edward Snowden a year ago. And smack in the middle, Bamford's 2012 revelation of the existence of a huge exabyte capable data storage facility then under construction in Bluffdale, Utah.

Given all this attention on recent events, it might come as a surprise to some that almost forty years ago Senator Frank Church convened a congressional committee to investigate reports of unlawful activities by US intelligence agencies, including illegal domestic wiretapping by the NSA. At the time, Church brought an oversight magnifying glass over what was then half-jokingly referred to as "No Such Agency." And then, like today, James Bamford was in the thick of it with a Snowden like cloak-and-dagger game of spy-vs-journalist.

It all began by giving testimony before the Church Committee. Writing yesterday in The Intercept, Bamford tells his first hand historical account of what led him to testify as a direct witness to NSA's wiretapping of domestic communications decades ago and then details the events that led to the publication of his first book The Puzzle Palace back in 1982:

...during the summer of 1975, as reports began leaking out from the Church Committee, I was surprised to learn that the NSA was claiming that it had shut down all of its questionable operations a year and a half earlier. Surprised because I knew the eavesdropping on Americans had continued at least into the prior fall, and may have still been going on. After thinking for a day or so about the potential consequences of blowing the whistle on the NSA—I was still in the Naval Reserve, still attending drills one weekend a month, and still sworn to secrecy with an active NSA clearance—I nevertheless decided to call the Church Committee.

But he didn't stop at the witness stand. Afterward, he continued researching the matter for a book. And the further he dug the more waves he made. Until someone slipped him a then recently declassified copy of a 1976 Justice Department memo [PDF] detailing a criminal investigation into illicit domestic spying by the NSA. But when agency officials discovered he had that document they took extraordinary measures attempting to get it back. From threatening to prosecute under the 1917 Espionage Act to retroactively reclassifying the memo to squelch its contents.

Fearing someone might break into his home and steal the manuscript, Bamford arranged to transport and secure a copy outside of US jurisdiction with a colleague at the Sunday Times of London. It was only upon the 1982 publication of Puzzle Palace that the agency dropped their pursuit of Bamford and his document as a lost cause. That's at least one stark difference between then and today when it comes to whistleblowers, back then they merely threatened espionage charges.

Yogi Berra famously once said, "It's like Deja Vu all over again." And though the Yankees' star wasn't speaking of illicit domestic wiretaps by the national security state, given a comparison of recent revelations to those detailed by Bamford decades earlier the quote certainly fits. In telling his story of how he published details about the last NSA Merry-Go-Round with warrantless wiretapping, Bamford shows us that our recent troubles of lawless surveillance aren't so unique. It's deja-vu all over again. But if deja vu is like a waking dream, this seems more a recurring nightmare for a body-politic lured to snoring slumber by a siren-song of political passivity.

That old Justice Department memo isn't likely to wake the public from their slumber. But within its pages is a stark warning we all should have heeded. As Bamford notes in that Intercept story, the report's conclusion that NSA lawlessness stems straight from the birth of the agency suggests a constitutional conflict systemic and intentional.

...the NSA’s top-secret “charter” issued by the Executive Branch, exempts the agency from legal restraints placed on the rest of the government. “Orders, directives, policies, or recommendations of any authority of the Executive branch relating to the collection ... of intelligence,” the charter reads, “shall not be applicable to Communications Intelligence activities, unless specifically so stated.” This so-called “birth certificate,” the Justice Department report concluded, meant the NSA did not have to follow any restrictions placed on electronic surveillance “unless it was expressly directed to do so.” In short, the report asked, how can you prosecute an agency that is above the law?
