Underground Experiment Confirms Fusion Powers the Sun

Slashdot - Wed, 08/27/2014 - 23:53
sciencehabit writes: Scientists have long believed that the power of the sun comes largely from the fusion of protons into helium, but now they can finally prove it (abstract). An international team of researchers using a detector buried deep below the mountains of central Italy has detected neutrinos—ghostly particles that interact only very reluctantly with matter—streaming from the heart of the sun. Other solar neutrinos have been detected before, but these particular ones come from the key proton-proton fusion reaction that is the first part of a chain of reactions that provides 99% of the sun's power.

Ask Slashdot: What To Do About Repeated Internet Overbilling?

Slashdot - Wed, 08/27/2014 - 23:33
An anonymous reader writes "AT&T has been overbilling my account based on overcounting DSL internet usage (they charge in 50 gigabyte units after the first 150). I have been using a Buffalo NFinity Airstation as a managed switch to count all traffic. As you may know, this device runs firmware based on dd-wrt and has hidden telnet functionality, so I am able to load a script to count traffic directly onto the device. I have an auto-scraper that collects the data and saves it on my computer's hard disk every two minutes while the computer is running. While it is not running, the 2 minute counters accumulate in RAM on the device. Power problems are not normally an issue here; and even when they are I can tell it has happened. The upshot of all this is I can measure the exact amount of download bandwidth and a guaranteed overestimate of upload bandwidth in bytes reliably. I have tested this by transferring known amounts of data and can account for every byte counted, including ethernet frame headers. AT&T's billing reporting reports usage by day only, lags two days, and uses some time basis other than midnight. It is also reading in my testing a fairly consistent 14% higher whenever the basis doesn't disturb the test by using too much bandwidth too close to midnight. AT&T has already refused to attempt to fix the billing meter, and asserts they have tested it and found it correct. Yet they refuse to provide a realtime readout of the counter that would make independent testing trivial. I've been through the agencies (CPUC, FCC, and Weights & Measures) and can't find one that is interested, AT&T will not provide any means for reasonable independent testing of the meter. It is my understanding that if there is a meter and its calibration cannot be checked, there is a violation of the law, yet I can't find an agency that can even accept such a claim (I'm not getting "your claim is meritless", but "we don't handle that"). If indeed they are not overbilling, my claim of no way to verify the meter still stands. My options are running thin here. So that my account can be identified by someone who recognizes the case: 7a6c74964fafd56c61e06abf6c820845cbcd4fc0 (bit commitment).

Eye Problems From Space Affect At Least 21 NASA Astronauts

Slashdot - Wed, 08/27/2014 - 22:13
SternisheFan sends this report from Universe Today: How does microgravity affect your health? One of the chief concerns of NASA astronauts these days is changes to eyesight. Some people come back from long-duration stays in space with what appears to be permanent changes, such as requiring glasses when previously they did not. And the numbers are interesting. A few months after NASA [said] 20% of astronauts may face this problem, a new study points out that 21 U.S. astronauts that have flown on the International Space Station for long flights (which tend to be five to six months) face visual problems. These include "hyperopic shift, scotoma and choroidal folds to cotton wool spots, optic nerve sheath distension, globe flattening and edema of the optic nerve," states the University of Houston, which is collaborating with NASA on a long-term study of astronauts while they're in orbit.

DoT Proposes Mandating Vehicle-To-Vehicle Communications

Slashdot - Wed, 08/27/2014 - 21:30
schwit1 sends word that the Dept. of Transportation's National Highway Traffic Safety Administration has given notice of a proposal (PDF) for a new car safety standard that would require vehicle-to-vehicle communication equipment in all new passenger cars and light trucks. The NHTSA thinks this will facilitate the development of new safety software for vehicles. They estimate it could prevent over 500,000 crashes (PDF) each year. "Some crash warning V2V applications, like Intersection Movement Assist and Left Turn Assist, rely on V2V-based messages to obtain information to detect and then warn drivers of possible safety risks in situations where other technologies have less capability. ... NHTSA believes that V2V capability will not develop absent regulation, because there would not be any immediate safety benefits for consumers who are early adopters of V2V." The submitter notes that this V2V communication would include transmission of a vehicle's location, which comes with privacy concerns.

How Red Hat Can Recapture Developer Interest

Slashdot - Wed, 08/27/2014 - 20:48
snydeq writes: Developers are embracing a range of open source technologies, writes Matt Asay, virtually none of which are supported or sold by Red Hat, the purported open source leader. "Ask a CIO her choice to run mission-critical workloads, and her answer is a near immediate 'Red Hat.' Ask her developers what they prefer, however, and it's Ubuntu. Outside the operating system, according to AngelList data compiled by Leo Polovets, these developers go with MySQL, MongoDB, or PostgreSQL for their database; Chef or Puppet for configuration; and ElasticSearch or Solr for search. None of this technology is developed by Red Hat. Yet all of this technology is what the next generation of developers is using to build modern applications. Given that developers are the new kingmakers, Red Hat needs to get out in front of the developer freight train if it wants to remain relevant for the next 20 years, much less the next two."

U.S. Senator: All Cops Should Wear Cameras

Slashdot - Wed, 08/27/2014 - 20:06
Several readers sent word that U.S. Senator Claire McCaskill (D-MO) has begun speaking in favor of mandatory cameras for police across the country. "Everywhere I go people now have cameras. And police officers are now at a disadvantage, because someone can tape the last part of an encounter and not tape the first part of the encounter. And it gives the impression that the police officer has overreacted when they haven't." This follows the recent controversy ove the shooting death of Michael Brown in a police incident, as well as a White House petition on the subject that rocketed to 100,000 signatures. McCaskill continued, "I would like to see us say, 'If you want federal funding in your community, you've got to have body cams on your officers. And I think that would go a long way towards solving some of these problems, and it would be a great legacy over this tragedy that's occurred in Ferguson, regardless of what the facts say at the end as to whether or not anyone is criminally culpable."

Scientists Craft Seamless 2D Semiconductor Junctions

Slashdot - Wed, 08/27/2014 - 19:21
vinces99 (2792707) writes Scientists have developed what they believe is the thinnest-possible semiconductor, a new class of nanoscale materials made in sheets only three atoms thick. The University of Washington researchers have demonstrated that two of these single-layer semiconductor materials can be connected in an atomically seamless fashion known as a heterojunction. This result could be the basis for next-generation flexible and transparent computing, better light-emitting diodes, or LEDs, and solar technologies. "Heterojunctions are fundamental elements of electronic and photonic devices," said senior author Xiaodong Xu, a UW assistant professor of materials science and engineering and of physics. "Our experimental demonstration of such junctions between two-dimensional materials should enable new kinds of transistors, LEDs, nanolasers, and solar cells to be developed for highly integrated electronic and optical circuits within a single atomic plane."

GOG Introduces DRM-Free Movie Store

Slashdot - Wed, 08/27/2014 - 18:04
Via Engadget comes news that GOG, the DRM-free game store platform, has launched a DRM-free movie store. The initial set of movies are gamer oriented, and you won't find major studio releases (yet, and not for a lack of trying on the part of GOG). From GOG: Our goal is to offer you cinema classics as well as some all-time favorite TV series with no DRM whatsoever, for you to download and keep on your hard drive or stream online whenever you feel like it. We talked to most of the big players in the movie industry and we often got a similar answer: "We love your ideas, but we do not want to be the first ones. We will gladly follow, but until somebody else does it first, we do not want to take the risk". DRM-Free distribution is not a concept their lawyers would accept without hesitation. We kind of felt that would be the case and that it's gonna take patience and time to do it, to do it, to do it right. That's quite a journey ahead of us, but every gamer knows very well that great adventures start with one small step. So why not start with something that feels very familiar? We offer you a number of gaming and Internet culture documentaries - all of them DRM-Free, very reasonably priced, and presenting some fascinating insight into topics close to a gamer's heart. Videos are mostly 1080p (~8GB for a 90 minute film) and can be acquired for about $6. They're using h.264/mp4 and not VP9/Matroska, but you can't have everything ;). If you don't want to download that much data, it looks like all of the videos are also available in 720p and 576p.

Limiting the Teaching of the Scientific Process In Ohio

Slashdot - Wed, 08/27/2014 - 17:25
frdmfghtr (603968) writes Over at Ars Technica, there's a story about a bill in the Ohio legislature that wants to downplay the teaching of the scientific process. From the article: "Specifically prohibiting a discussion of the scientific process is a recipe for educational chaos. To begin with, it leaves the knowledge the kids will still receive—the things we have learned through science—completely unmoored from any indication of how that knowledge was generated or whether it's likely to be reliable. The scientific process is also useful in that it can help people understand the world around them and the information they're bombarded with; it can also help people assess the reliability of various sources of information." The science standards would have "...focus on academic and scientific knowledge rather than scientific processes; and prohibit political or religious interpretation of scientific facts in favor of another." Political interpretation of scientific facts include humans contributing to climate change according to the bill's sponsor, who also thinks intelligent design would be OK under the law.

New submitter SomeoneFromBelgium (3420851) writes According to Bloomberg a leaked climate report from the IPPC speaks of "Irreversible Damage." The warnings in the report are, as such, not new but the tone of voice is more urgent and more direct than ever. It states among other things that global warming already is affecting "all continents and across the oceans," and that "risks from mitigation can be substantial, but they do not involve the same possibility of severe, widespread, and irreversible impacts as risks from climate change, increasing the benefits from near-term mitigation action."

Chromium 37 Launches With Major Security Fixes, 64-bit Windows Support

Slashdot - Wed, 08/27/2014 - 16:05
An anonymous reader writes Google has released Chrome/Chromium version 37 for Windows, Mac, and Linux. Among the changes are better-looking fonts on Windows and a revamped password manager. There are 50 security fixes, including several to patch a sandbox escaping vulnerability. The release also brings stable 64-bit Windows support which ...offers many benefits for speed, stability and security. Our measurements have shown that the native 64-bit version of Chrome has improved speed on many of our graphics and media benchmarks. For example, the VP9 codec that’s used in High Definition YouTube videos shows a 15% improvement in decoding performance. Stability measurements from people opted into our Canary, Dev and Beta 64-bit channels confirm that 64-bit rendering engines are almost twice as stable as 32-bit engines when handling typical web content. Finally, on 64-bit, our defense in depth security mitigations such as Partition Alloc are able to far more effectively defend against vulnerabilities that rely on controlling the memory layout of objects.

Time Warner Cable Experiences Nationwide Internet Outage

Wolfrider (856) writes Reports are coming in from multiple U.S. states that TWC is having a major Internet outage since early this morning. ... TWC's customer service reps are reportedly a bit overwhelmed by call volume at the moment, and no ETA yet. According to CNET, most locations should be more-or-less back online as of 7 a.m. EDT or so (my TWC connection came back around 7:30 a.m. EDT). TWC says it's maintenance gone wrong: In response to a query by CNET, Time Warner Cable issued this statement: "At 430am ET this morning during our routine network maintenance, an issue with our Internet backbone created disruption with our Internet and On Demand services. As of 6am ET services were largely restored as updates continue to bring all customers back online."

Statistics Losing Ground To CS, Losing Image Among Students

theodp (442580) writes Unless some things change, UC Davis Prof. Norman Matloff worries that the Statistician could be added to the endangered species list. "The American Statistical Association (ASA) leadership, and many in Statistics academia," writes Matloff, "have been undergoing a period of angst the last few years, They worry that the field of Statistics is headed for a future of reduced national influence and importance, with the feeling that: [1] The field is to a large extent being usurped by other disciplines, notably Computer Science (CS). [2] Efforts to make the field attractive to students have largely been unsuccessful." Matloff, who has a foot in both the Statistics and CS camps, but says, "The problem is not that CS people are doing Statistics, but rather that they are doing it poorly. Generally the quality of CS work in Stat is weak. It is not a problem of quality of the researchers themselves; indeed, many of them are very highly talented. Instead, there are a number of systemic reasons for this, structural problems with the CS research 'business model'." So, can Statistics be made more attractive to students? "Here is something that actually can be fixed reasonably simply," suggests no-fan-of-TI-83-pocket-calculators-as-a-computational-vehicle Matloff. "If I had my druthers, I would simply ban AP Stat, and actually, I am one of those people who would do away with the entire AP program. Obviously, there are too many deeply entrenched interests for this to happen, but one thing that can be done for AP Stat is to switch its computational vehicle to R."

Fermilab Begins Testing Holographic Universe Theory

Slashdot - Wed, 08/27/2014 - 14:03
Back in 2009, researchers theorized that space could be a hologram.Four years ago, Fermilab proposed testing the theory, and the experiment is finally going online. Jason Koebler (3528235) writes Operating with cutting-edge technology out of a trailer in rural Illinois, government researchers started today on a set of experiments that they say will help them determine whether or not you and me and everything that exists are living in a two-dimensional holographic universe. In a paper explaining the theory, Craig Hogan, director of the Department of Energy's Fermilab Center for Particle Astrophysics writes that "some properties of space and time that seem fundamental, including localization [where things are], may actually emerge only as a macroscopic approximation from the flow of information in a quantum system." In other words, the location of places in space may constantly fluctuate ever so slightly, which would suggest we're living in a hologram.
