An anonymous reader writes with news that the NFL has reached out for some help answering the questions raised by deflate-gate. "Yep, it's for real. The law firm representing the NFL (Paul, Weiss, Rifkind, Wharton & Garrison) has reached out to Columbia University's department of physics to recruit an expert on 'gas physics' to help determine, as has been reported, the 'environmental impacts on inflated footballs.' This is one of those rare times when the jocks turn to the nerds, so fellow fans of molecules and momentum — climb out of that gym locker you were stuffed into — this is our moment. Stand tall. And do the wave....They want to talk to a physicist, I presume, to help determine if a drop in temperature — a slowing of the air molecules inside the football — can explain the low pressure that was found in some of the balls used in the A.F.C. championship game two weeks ago between the New England Patriots and the Indianapolis Colts."

Test Shows Big Data Text Analysis Inconsistent, Inaccurate 21

from the you'll-love-these-links dept.
DillyTonto writes The "state of the art" in big-data (text) analysis turns out to use a method of categorizing words and documents that, when tested, offered different results for the same data 20% of the time and was flat wrong another 10%, according to researchers at Northwestern. The Researchers offered a more accurate method, but only as an example of how to use community detection algorithms to improve on the leading method (LDA). Meanwhile, a certain percentage of answers from all those big data installations will continue to be flat wrong until they're re-run, which will make them wrong in a different way.

Obama Proposes One-Time Tax On $2 Trillion US Companies Hold Overseas 263

from the pay-the-man dept.
mrspoonsi writes with news about a new proposed tax on overseas profits to help pay for a $478 billion public works program of highway, bridge and transit upgrades. President Barack Obama's fiscal 2016 budget would impose a one-time 14 percent tax on some $2 trillion of untaxed foreign earnings accumulated by U.S. companies abroad and use that to fund infrastructure projects, a White House official said. The money also would be used to fill a projected shortfall in the Highway Trust Fund. "This transition tax would mean that companies have to pay U.S. tax right now on the $2 trillion they already have overseas, rather than being able to delay paying any U.S. tax indefinitely," the official said. "Unlike a voluntary repatriation holiday, which the president opposes and which would lose revenue, the president's proposed transition tax is a one-time, mandatory tax on previously untaxed foreign earnings, regardless of whether the earnings are repatriated." In the future, the budget proposes that U.S. companies pay a 19 percent tax on all of their foreign earnings as they are earned, while a tax credit would be issued for foreign taxes paid, the official said.

Ask Slashdot: Is There a Modern IP Webcam That Lets the User Control the Output? 126

Posted by samzenpus
from the a-picture-is-worth-a-thousand-words dept.
First time accepted submitter Tronster writes Owners of a local shop have a menu that changes daily and wanted an IP webcam to update an image on their web-site. After a frustrating 2 hours of a "Hikvision" refusing to behave, I threw in the towel and looked for a better camera to recommend. The biggest issue today is that the new webcams that come out don't support FTP, they all support sending images/video direct to a "private cloud" (e.g., Simplicam, Dropcam, etc...). Google has been no help; all the sites are either outdated in terms of ranking or the most recent ones recommend a Foscam. They previously tried one of these and it's image quality was too poor. While security systems and home automation has been discussed recently, I haven't found any recent discussions on webcams that give a user control of where the content is sent. Does anyone in the Slashdot community have recommendations, reputable sites that are up-to-date in rankings, and/or hacks to have control over some of these newer cameras?

First time accepted submitter bronger writes After six years of closed-source development, the Research Centre Jülich published its database solution for laboratory samples and processes as open source, while continuing maintaining it. JuliaBase is a framework written in Python/Django that enables research institution or research group to set up browser-based samples tracking and measurement management easily. Next to Bika and LabLey, this is one of the very few open source LIMS systems, and in contrast to the others, not specialized in biomedicine or service labs.

NASA Launches Satellite To Observe Soil Moisture 16

from the how-dry-I-am dept.
An anonymous reader sends word that NASA has launched an Earth-observing satellite, which will measure the amount of moisture in soil. "In one of the space agency's bolder projects, a newly launched NASA satellite will monitor western drought and study the moisture, frozen and liquid in Earth's soil. It's true that a satellite can't possibly fix the devastating drought that has been plaguing the American West for the last years. It is also true that it can't possibly change the fact that California has just gone through the driest month in recorded history. But what NASA plans to do is to provide the possibility of understanding the patterns of this extreme weather and, perhaps, foresee how much worse it could actually become. Called the SMAP (Soil Moisture Active Passive Satellite), this new, unmanned project was successfully launched on Saturday atop the United Launch Alliance Delta II Rocket. The launch took place at the California Vandenberg Air Force base at exactly 9:22 AM EST. With the successful launch, NASA just kick started a three year, $916 million mission focused on measuring and forecasting droughts, floods and other possible natural disasters that might come our way in the future."

The NFL Wants You To Think These Things Are Illegal 141

An anonymous reader writes: Professional sports have become a minefield of copyright and trademark issues, and no event moreso than the Super Bowl. Sherwin Siy of Public Knowledge has an article debunking some of the things the NFL has convinced people they can't do, even through they're perfectly legal. For example, you've probably heard the warning about how "descriptions" and "accounts" of the game are prohibited without the NFL's consent. That's all hogwash: "The NFL would be laughed out of court for trying to prevent them from doing so—just because you have a copyright in a work doesn't mean you can prevent people from talking about it. Copyright simply doesn't extend that far." Recording the game and watching it later is just fine, too.

So, will you be paying attention to the game today? Ignoring it? Practicing your cultivated disinterest?

Police Stations Increasingly Offer Safe Haven For Craigslist Transactions 103

HughPickens.com writes: Lily Hay Newman reports at Future Tense that the police department in Columbia, Missouri recently announced its lobby will be open 24/7 for people making Craigslist transactions or any type of exchange facilitated by Internet services. This follows a trend begun by police stations in Virginia Beach, East Chicago and Boca Raton. Internet listings like Craigslist are, of course, a quick and convenient way to buy, sell, barter, and generally deal with junk. But tales of Craigslist-related assaults, robberies, and murders where victims are lured to locations with the promise of a sale, aren't uncommon. Also, an item being sold could be broken or fake, and the money being used to buy it could be counterfeit.

"Transactions should not be conducted in secluded parking lots, behind a building, in a dark location especially when you're dealing with strangers. Someone you've never met before – you have no idea what their intentions are – whether they have evil intent or the best of intentions," says Officer James Cason Jr. With surveillance cameras running 24 hours a day, plus the obvious bonus of a constant police presence, meeting in the lobby of the police department can help weed out people trying to rip others off. "People with stolen items may not want to meet at the police department," says Bryana Maupin.

OpenSSH Will Feature Key Discovery and Rotation For Easier Switching To Ed25519 75

Posted by Soulskill
from the all-about-the-upgrades dept.
ConstantineM writes: OpenSSH developer Damien Miller has posted about a new feature he implemented and committed for the next upcoming 6.8 release of OpenSSH hostkeys@openssh.com — an OpenSSH extension to the SSH protocol for sshd to automatically send all of its public keys to the client, and for the client to automatically replace all keys of such server within ~/.ssh/known_hosts with the fresh copies as supplied (provided the server is trusted in the first place, of course). The protocol extension is simple enough, and is aimed to make it easier to switch over from DSA to the OpenSSL-free Ed25519 public keys. It is also designed in such a way as to support the concept of spare host keys being stored offline, which could then seamlessly replace main active keys should they ever become compromised.

The Pirate Bay Is Back Online, Properly 134

New submitter cbiltcliffe writes: About a month ago, we discussed news that the Pirate Bay domain name was back online. This story mentioned a timer, which supposedly showed the time since the police raid. I didn't notice at the time, but a more recent check showed this counter was counting down, not up, with a time set to reach zero at the end of January. Sometime around a week ago, the waving pirate flag video changed to a graphic of an orange phoenix, and a disabled search box showed up. I've been watching the site since, and now, about 12 hours before the timer was to reach zero, the site is back up, complete with searches.

NASA Looking At Nuclear Thermal Rockets To Explore the Solar System 186

from the i'll-order-a-dozen dept.
MarkWhittington writes: Officially, NASA has been charged with sending astronauts to Mars sometime in the 2030s. Toward that end, according to a story in Universe Today, space agency engineers at the Marshall Space Flight Center are looking at an old concept for interplanetary travel, nuclear thermal engines. "...according to the report (cached), an NTP rocket could generate 200 kWt of power using a single kilogram of uranium for a period of 13 years – which works out of to a fuel efficiency rating of about 45 grams per 1000 MW-hr. In addition, a nuclear-powered engine could also provide superior thrust relative to the amount of propellant used." However, some doubts have been expressed whether NASA will be granted the budget to develop such engines.

Bryce writes: Four years since the last major Inkscape release, now news is out about version 0.91 of this powerful vector drawing and painting tool. The main reason for the multi-year delay is that they've switched from their old custom rendering engine to using Cairo now, improving their support for open source standards. This release also adds symbol libraries and support for Visio stencils, cross platform WMF and EMF import and export, a native Windows 64-bit build, scads of bug fixes, and much more.

Can Students Have Too Much Tech? 165

Posted by Soulskill
from the maybe-4th-graders-don't-need-weaponized-roombas dept.
theodp writes: In a NY Times Op Ed, developmental psychologist Susan Pinker goes against the conventional White House wisdom about the importance of Internet connectivity for schoolchildren and instead argues that students can have too much tech. "More technology in the classroom has long been a policy-making panacea," Pinker writes. "But mounting evidence shows that showering students, especially those from struggling families, with networked devices will not shrink the class divide in education. If anything, it will widen it." Tech can help the progress of children, Pinker acknowledges, but proper use is the rub. As a cautionary tale, Pinker cites a study by Duke economists that tracked the academic progress of nearly one million disadvantaged middle-school students against the dates they were given networked computers. The news was not good. "Students who gain access to a home computer between the 5th and 8th grades tend to witness a persistent decline in reading and math scores," the economists wrote, adding that license to surf the Internet was also linked to lower grades in younger children.

GeForce GTX 980 and 970 Cards From MSI, EVGA, and Zotac Reviewed 61

MojoKid writes: In all of its iterations, NVIDIA's Maxwell architecture has proven to be a good performing, power-efficient GPU thus far. At the high-end of the product stack is where some of the most interesting products reside, however. When NVIDIA launches a new high-end GPU, cards based on the company's reference design trickle out first, and then board partners follow up with custom solutions packing unique cooling hardware, higher clocks, and sometimes additional features. With the GeForce GTX 970 and GTX 980, NVIDIA's board partners were ready with custom solutions very quickly. These three custom GeForce cards, from enthusiast favorites EVGA, MSI, and Zotac represent optimization at the high-end of Maxwell. Two of the cards are GTX 980s: the MSI GTX 980 Gaming 4G and the Zotac GeForce GTX 980 AMP! Omgea, the third is a GTX 970 from EVGA, their GeForce GTX 970 FTW with ACX 2.0. Besides their crazy long names, all of these cards are custom solutions, that ship overclocked from the manufacturer. In testing, NVIDIA's GeForce GTX 980 was the fastest, single-GPU available. The custom, factory overclocked MSI and Zotac cards cemented that fact. Overall, thanks to a higher default GPU-clock, the MSI GTX 980 Gaming 4G was the best performing card. EVGA's GeForce GTX 970 FTW was also relatively strong, despite its alleged memory bug. Although, as expected, it couldn't quite catch the higher-end GeForce GTX 980s, but occasionally outpaced the AMD's top-end Radeon R9 290X.
