Ask Slashdot: Why Can't Google Block Spam In Gmail?
Posted by News Fetcher on October 13 '14 at 09:15 AM
By timothy from Slashdot's spy-vs-jerkface department:
An anonymous reader writes Every day my gmail account receives 30-50 spam emails. Some of it is UCE, partially due to a couple dingbats with similar names who apparently think my gmail account belongs to them. The remainder looks to be spambot or Nigerian 419 email. I also run my own MX for my own domain, where I also receive a lot of spam. But with a combination of a couple DNSBL in my sendmail config, SpamAssassin, and procmail, almost none of it gets through to my inbox. In both cases there are rare false positives where a legit email ends up in my spam folder, or in the case of my MX, a spam email gets through to my Inbox, but these are rare occurrences. I'd think with all the Oompa Loompas at the Chocolate Factory that they could do a better job rejecting the obvious spam emails. If they did it would make checking for the occasional false positives in my spam folder a teeny bit easier. For anyone who's responsible for shunting Web-scale spam toward the fate it deserves, what factors go into the decision tree that might lead to so much spam getting through?

The Correct Response To Photo Hack Victim-Blamers
Posted by News Fetcher on October 13 '14 at 08:30 AM
By samzenpus from Slashdot's who's-to-blame department:
Bennett Haselton writes As commenters continue to blame Jennifer Lawrence and other celebrities for allowing their
nude photos to be stolen, there is only one rebuttal to the victim-blaming which actually makes sense:
that for the celebrities taking their nude selfies, the probable benefits of their actions
outweighed the probable negatives. Most of the other rebuttals being offered,
are logically incoherent, and, as such, are not likely to change the minds of the victim-blamers.

Raspberry Pi Sales Approach 4 Million
Posted by News Fetcher on October 13 '14 at 07:45 AM
By timothy from Slashdot's just-a-small-hobby department:
Eben Upton's reboot of the spirit of the BBC Micro in the form of the Raspberry Pi would have been an interesting project even if it had only been useful in the world of education. Upton wanted, after all, to give the kind of hands-on, low-level interaction with computing devices that he saw had gone missing in schools. Plenty of rPis are now in that educational, inspirational role, but it turns out that the world was waiting (or at least ready) for a readily usable, cheap, all-in-one computer, and the Raspberry Pi arrived near the front of a wave that now includes many other options. Sales boomed, and we've mentioned a few of the interesting milestones, like the millionth unit made in the UK and the two-millionth unit overall. Now, according to TechCrunch the Raspberry Pi is getting close to 4 million units sold, having just passed 3.8 million, as reported in a tweet. If you have a Raspberry Pi, what are you using it for now, and what would you like to see tweaked in future versions?

Birth Control Pills Threaten Fish Stocks
Posted by News Fetcher on October 13 '14 at 07:15 AM
By samzenpus from Slashdot's all-mixed-up department:
BarbaraHudson writes Experimental research has shown that small amounts of estrogen in waste water can lead to rapid large-scale changes in fish populations. From the article: "The lead researcher of a new study is calling for improvements to some of Canada's waste water treatment facilities after finding that introducing the birth control pill in waterways created a chain reaction in a lake ecosystem that nearly wiped out a freshwater fish. 'Right away, the male fish started to respond to the estrogen exposure by producing egg yolk proteins and shortly after that they started to develop eggs,' she said in an interview from Saint John, N.B. 'They were being feminized.' Kidd said shortly after introducing the estrogen, the number of fathead minnow crashed, reducing numbers to just one per cent of the population. 'It was really unexpected that they would react so quickly and so dramatically,' she said. 'The crash in the population was very evident and very dramatic and very rapid and related directly to the estrogen addition.'" Estrogen pollution in waterways has been an issue for over a decade now.

PETA Is Not Happy That Google Used a Camel To Get a Desert "StreetView"
Posted by News Fetcher on October 13 '14 at 07:00 AM
By samzenpus from Slashdot's the-camera-that-broke-the-camels-back department:
First time accepted submitter flopwich writes Google used a camel-mounted camera to get a 'street view' of a stretch of desert in the United Arab Emirates. PETA's director Ingrid E. Newkirk is upset about it, saying they should have used jeeps. "These days, jeeps are in common use in the desert, as are light planes and even dune buggies, and satellite images could also easily have been taken instead," she said. "(Google) should leave camels out of its activites altogether."

Hawking Radiation Mimicked In the Lab
Posted by News Fetcher on October 13 '14 at 07:00 AM
By samzenpus from Slashdot's old-bob department:
Annanag writes *Nothing* escapes a black hole, right? Except 40 years ago Stephen Hawking threw a spanner in the works by suggesting that, courtesy of quantum mechanics, some light particles can actually break free of a black hole's massive pull. Then you have the tantalizing question of whether information can also escape, encoded in that so-called 'Hawking radiation'. The only problem being that no one has ever been able to detect Hawking radiation being emitted from a black hole. BUT a physicist has now come closer than ever before to creating an imitation of a black hole event horizon in the lab, opening up a potential avenue for investigating Hawking radiation and exploring how quantum mechanics and general relativity might be brought together.

Linux Foundation Launches Open Source Dronecode Project
Posted by News Fetcher on October 13 '14 at 05:45 AM
By samzenpus from Slashdot's open-to-the-public department:
garymortimer writes with news about a project that hopes to create an open source code platform for drones. "The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux and collaborative development, today announced the founding of the Dronecode Project. The Project will bring together existing open source drone projects and assets under a nonprofit structure governed by The Linux Foundation. The result will be a common, shared open source platform for Unmanned Aerial Vehicles (UAVs). Founding members include 3D Robotics, Baidu, Box, DroneDeploy, Intel, jDrones, Laser Navigation, Qualcomm, SkyWard, Squadrone System, Walkera and Yuneec. Dronecode includes the APM UAV software platform and associated code, which until now has been hosted by 3D Robotics, a world leader in advanced UAV autopilot and autonomous vehicle control. The company was co-founded by Chris Anderson, formerly editor-in-chief of Wired"

Statisticians Uncover What Makes For a Stable Marriage
Posted by News Fetcher on October 13 '14 at 05:00 AM
By samzenpus from Slashdot's by-the-numbers department:
HughPickens.com writes Randy Olson, a Computer Science grad student who works with data visualizations, writes about seven of the biggest factors that predict what makes for a long term stable marriage in America. Olson took the results of a study that polled thousands of recently married and divorced Americans and and asked them dozens of questions about their marriage (PDF): How long they were dating, how long they were engaged, etc. After running this data through a multivariate model, the authors were able to calculate the factors that best predicted whether a marriage would end in divorce. "What struck me about this study is that it basically laid out what makes for a stable marriage in the US," writes Olson. Here are some of the biggest factors:

First Man To Walk In Space Reveals How Mission Nearly Ended In Disaster
Posted by News Fetcher on October 13 '14 at 04:15 AM
By timothy from Slashdot's complicated-endeavor department:
wired_parrot writes Nearly fifty years after the first spacewalk by soviet cosmonaut Alexei Leonov, he's given a rare interview to the BBC revealing how the mission very nearly ended in disaster. Minutes after he stepped into space, Leonov realised his suit had inflated like a balloon, preventing him from getting back inside. Later on, the cosmonauts narrowly avoided being obliterated in a huge fireball when oxygen levels soared inside the craft. And on the way back to Earth, the crew was exposed to enormous G-forces, landing hundreds of kilometres off target in a remote corner of Siberia populated by wolves and bears.

Samsung's Wi-Fi Upgrades Promise Speeds Up to 4.6Gbps
Posted by News Fetcher on October 13 '14 at 01:15 AM
By timothy from Slashdot's another-shifting-bottleneck department:
The Register describes an advance in wireless speed announced by Samsung, which could make possible Wi-Fi speeds of up to 4.6Gbps in any device equipped with the new technology. By using “wide-coverage beam-forming antenna” and “eliminating co-channel interference, regardless of the number of devices using the same network” Samsung says it has cracked the problem and that products using its 802.11 ab standard could go on sale next year. Early products to use the technology will include “audio visual and medical devices, as well as telecommunications equipment.” Samsung also says the technology will be “integral to developments relevant to the Samsung Smart Home and other initiatives related to the Internet of Things.”

WhatsApp's Next Version To Include VoIP Calls and Recording
Posted by News Fetcher on October 12 '14 at 10:00 PM
By timothy from Slashdot's everything-that-converges department:
An anonymous reader writes that WhatsApp is adding a feature that may elevate it for many users' purposes: VoIP. "Apps like Viber, Skype, Tango and Google Hangout already support VoIP, which allows you to make voice calls over a broadband connection. Beyond WhatsApp's huge pool of over 600 million active users, which will undoubtedly disrupt cell service providers' payment model, what is even more intriguing is the VoIP recording feature. With the exception of third-party add-ons available for Skype, no other VoIP app includes this feature."

Oxytocin Regulates Sociosexual Behavior In Female Mice
Posted by News Fetcher on October 12 '14 at 07:15 PM
By timothy from Slashdot's take-two-of-these-and-I'll-make-breakfast-in-the-morning department:
Chipmunk100 writes In a research article in the journal Cell scientists report that there is a subset of neurons that are vital in social interest of female mice for males during estrus, the sexually receptive phase of their cycle. They say that these neurons are responsive to oxytocin. The level of oxytocin rise when we hug or kiss a loved one. The BBC has an article on the findings as well, and reports that

Without [oxytocin], female mice were no more attracted to a mate than to a block of Lego ... [The affected] neurons are situated in the prefrontal cortex, an area of the brain important for personality, learning and social behaviour.

Both when the hormone was withheld and when the cells were silenced, the females lost interest in mating during oestrous, which is when female mice are sexually active.

Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days
Posted by News Fetcher on October 12 '14 at 04:15 PM
By timothy from Slashdot's there's-an-obvious-way-to-silence-the-critics department:
WheezyJoe (1168567) writes The E-Cat (or "Energy Catalyzer") is an alleged cold fusion device that produces heat from a low-energy nuclear reaction where nickel and hydrogen fuse into copper. Previous reports have tended to suggest the technology is a hoax, and the inventor Andrea Rossi's reluctance to share details of the device haven't helped the situation. ExtremeTech now reports that "six (reputable) researchers from Italy and Sweden" have "observed a small E-Cat over 32 days, where it produced net energy of 1.5 megawatt-hours, "far more than can be obtained from any known chemical sources in the small reactor volume."... "The researchers, analyzing the fuel before and after the 32-day burn, note that there is an isotope shift from a "natural" mix of Nickel-58/Nickel-60 to almost entirely Nickel-62 — a reaction that, the researchers say, cannot occur without nuclear reactions (i.e. fusion)." The paper (PDF) linked in the article concludes that the E-cat is "a device giving heat energy compatible with nuclear transformations, but it operates at low energy and gives neither nuclear radioactive waste nor emits radiation. From basic general knowledge in nuclear physics this should not be possible. Nevertheless we have to relate to the fact that the experimental results from our test show heat production beyond chemical burning, and that the E-Cat fuel undergoes nuclear transformations. It is certainly most unsatisfying that these results so far have no convincing theoretical explanation, but the experimental results cannot be dismissed or ignored just because of lack of theoretical understanding. Moreover, the E-Cat results are too conspicuous not to be followed up in detail. In addition, if proven sustainable in further tests the E-Cat invention has a large potential to become an important energy source." The observers understandably hedge a bit, though: The researchers are very careful about not actually saying that cold fusion/LENR is the source of the E-Cat’s energy, instead merely saying that an “unknown reaction” is at work. In serious scientific circles, LENR is still a bit of a joke/taboo topic. The paper is actually somewhat comical in this regard: The researchers really try to work out how the E-Cat produces so much darn energy — and they conclude that fusion is the only answer — but then they reel it all back in by adding: “The reaction speculation above should only be considered as an example of reasoning and not a serious conjecture.”

Microsoft's Quantum Mechanics

By timothy from Slashdot's not-so-strange-bedfellows department:
New submitter catchblue22 writes MIT Technology Review has an excellent article summarizing the current state of quantum computing. It focuses on the efforts of Microsoft and Alcatel-Lucent's Bell Labs to build stable qubits over the past few years. "In 2012, physicists in the Netherlands announced a discovery in particle physics that started chatter about a Nobel Prize. Inside a tiny rod of semiconductor crystal chilled cooler than outer space, they had caught the first glimpse of a strange particle called the Majorana fermion, finally confirming a prediction made in 1937. It was an advance seemingly unrelated to the challenges of selling office productivity software or competing with Amazon in cloud computing, but Craig Mundie, then heading Microsoft's technology and research strategy, was delighted. The abstruse discovery — partly underwritten by Microsoft — was crucial to a project at the company aimed at making it possible to build immensely powerful computers that crunch data using quantum physics. "It was a pivotal moment," says Mundie. "This research was guiding us toward a way of realizing one of these systems."

Four Dutch Uberpop Taxi Drivers Arrested, Fined

By timothy from Slashdot's not-so-laissez-faire department:
An anonymous reader writes with news that authorities in the Netherlands have arrested four drivers sharing their car for money through the Uberpop app. The drivers where then released with a fine of EUR 4200 (USD 5300) each and further threatened with additional fines of EUR 10000 (USD 12600) for each time they might be caught doing it again. While similar bullying applied to short rentals of private rooms through sites like Airbnb hasn't had the same success so far the thoughts go to the fined drivers, hoping they won't ever be caught carrying their grandmother to the supermarket then have to explain how they dared.The Uber company says it will "fully support" the affected drivers."

An anonymous reader writes A threat campaign tracking report released by Volexity shows that a number of high profile websites related to the Hong Kong democracy movement have been infected with malware. This malware targets both the web servers themselves as well as website visitors. The sophistication and scope of the malware likely points to government involvement as has been the case in previous campaigns targeting Asian charities and government reform organizations.

Crowdsourced Remake "The Empire Strikes Back Uncut" Now Complete
Posted by News Fetcher on October 12 '14 at 12:15 PM
By timothy from Slashdot's even-luke-lent-a-hand department:
Two and a half years ago, we posted news of the completion of the Star Wars Uncut project. Now, reader kdataman writes that another fan-made Star Wars movie remake is ready to watch; this time it's Empire: 480 fan-created 15-second clips have been assembled to remake the entire movie, scene for scene (but not always word for word). The variations swing from professional production values to cardboard cutouts, but they are all creative and many are hilarious. Hard to pick a favorite scene but the guys at MTV selected a few highlights.

Feces-Filled Capsules Treat Bacterial Infection
Posted by News Fetcher on October 12 '14 at 10:45 AM
By timothy from Slashdot's you'll-note-not-many-politicians-die-of-c-diff department:
sciencehabit writes Clostridium difficile infections kill approximately 14,000 Americans every year, often because the diarrhea-causing bacteria are highly resistant to standard antibiotics. Now, scientists have found an unusual way to combat the bugs: human feces in pill form. In the new study, researchers show that frozen fecal matter encapsulated in clear, 1.6 g synthetic pills was just as safe and effective as traditional fecal transplant techniques at treating C. difficile. Within 8 weeks or less, 18 out of 20 participants saw a complete resolution of diarrhea after consuming 30 or 60 of the feces-filled capsules. "It's probably not the best experience of your life," says team leader Ilan Youngster, a pediatric infectious disease doctor at Harvard University. "But it beats getting a tube stuck down your throat or a colonoscopy or having C. diff."

Ask Slashdot: Best Books On the Life and Work of Nikola Tesla?
Posted by News Fetcher on October 12 '14 at 10:15 AM
By timothy from Slashdot's you-mean-the-ones-they-haven't-hidden-from-you department:
An anonymous reader writes The internet is full of interesting nuggets of info about Nikola Tesla's life and scientific exploits: The time a young Tesla improved an electric motor for Edison, and Edison simply would not pay Tesla the monetary reward he had promised him earlier. The friction between Tesla and wealthy industrialist J.P. Morgan, and Tesla's friendship with (kinder) industrialist George Westinghouse. The 2 different times Tesla's main laboratory burned to the ground. The time a Tesla lab experiment reportedly caused a small earthquake to trigger in lower Manhattan. Tesla's (never quite fulfilled) dream of transmitting electricity across great distances without using wires or cables, etc. All this fascinating stuff, and more, about Tesla's life is out there, mostly in shortish snippets — and sometimes woven into outright conspiracy theories — on the internet for anyone to examine. Now to my question: What are the best books to read to get a fuller picture of Nikola Tesla's life and work? Preferably something well researched and factually accurate. Are there any good documentaries or movies (apart from David Bowie playing a wizard-like Tesla in "The Prestige")? Why is Thomas Edison so well known and covered in education/popular culture, and the equally prolific and ingenious Tesla a "mysterious and ghostly figure" by comparison?

Microsoft Develops Analog Keyboard For Wearables, Solves Small Display Dilemma
Posted by News Fetcher on October 12 '14 at 09:15 AM
By timothy from Slashdot's finger-spelling department:
MojoKid writes Have you ever tried hunting and pecking on a miniature keyboard that's been crammed onto a smartwatch's tiny display? Unless the tips of your fingers somehow resemble that of a stylus, you're in for a challenge. Interestingly enough, it's Microsoft that might have the most logical solution for typing on small size displays running Google's Android Wear platform. Microsoft's research division has built an analog keyboard prototype for Android Wear that eliminates the need to tap at tiny letters, and instead has you write them out. On the surface, such a solution seems like you'd be trading one tedious task for another, though a demo of the technology in action shows that this could be a promising solution — watch how fast the guy in the video is able to hammer out a response.
