AMD Forces a LibreOffice Speed Boost With GPU Acceleration 144

New submitter samtuke writes: AMD processors get rated and reviewed based on performance. It is in our self-interest to make things work really, really fast on AMD hardware. AMD engineers contribute to LibreOffice, for good reason. Think about what happens behind a spreadsheet calculation. There can be a huge amount of math. Writing software to take advantage of a Graphics Processing Unit (GPU) for general purpose computing is non-trivial. We know how to do it. AMD engineers wrote OpenCL kernels, and contributed them to the open source code base. Turning on the OpenCL option to enable GPU Compute resulted in a 500X+ speedup, about ¼ second vs. 2minutes, 21 seconds. Those measurements specifically come from the ground-water use sample from this set of Libre Office spreadsheets.

Greeting my loyal subjects. Are you tired of the mainstream media runaround, flimflam and jimjam? Me too, so I'm cutting through the b.s. like a hot knife through pigeonpoop to bring you the straight dick right from the horse's mouth. Friends, brothers, countrymen, remember this word: toad. If you remember the word that I indicated to you above, all will become clear. The key to understanding is in your hands. Rejoice!

The OpenSSH Bug That Wasn't 55

badger.foo writes: Get your facts straight before reporting, is the main takeaway from Peter Hansteen's latest piece, The OpenSSH Bug That Wasn't. OpenSSH servers that are set up to use PAM for authentication and with a very specific (non-default on OpenBSD and most other places) setup are in fact vulnerable, and fixing the configuration is trivial.

Ask Slashdot: Building an Open Source Community For a Proprietary Software Product? 85

An anonymous reader writes: I run a company that develops scientific computing software. Our core product is a traditional proprietary application — we develop the software and deliver the "binaries" to our customers. We're considering changing our deployment to include all of the source code and giving our customers some additional rights to explore and extend it. The codebase is HTML/JavaScript/Python/SQL, so a lot of the code is available in some form already, albeit minified or byte compiled.

Because we are in a scientific domain, most of our customers use Open Source software alongside our product. We also maintain Open Source projects and directly support others. We're strong supporters of Open Source and understand the value of having access to the source code.

We also support a free (as in beer) version of the software with a smaller feature set (production and enterprise elements that individual users don't need are removed). We'd like that version to use the same model as well to give users that don't need the full commercial version the ability to extend the software and submit patches back to us for inclusion in future releases.

Overall, we'd really like to find a model that allows our core product to work more like an Open Source product while maintaining control over the distribution rights. We'd like to foster a community around the product but still generate revenue to fund it. In our space, the "give the product away but pay for support" model has never really worked. The market is too small and, importantly, most customers understand our value proposition and have no problem with our annual license model.

We've looked at traditional dual licensing approaches, but don't think they're really right fit, either. A single license that gives users access to the code but limits the ability to redistribute the code and distribute patches to the "core" is what we'd prefer. My questions for the Slashdot community: Does anyone have direct experience with models like this? Are there existing licenses that we should look at? What companies have succeeded doing this? Who has failed?

Scientists Identify Sixth Taste: Fat 90

New submitter shuheng writes with news that a study out of Purdue claims to have identified the sixth distinct taste known to humans: fat. The scientists say it should be called oleogustus which means "fatty taste" in Latin (abstract). Professor Richard Mattes said, Most of the fat we eat is in the form of triglycerides, which are molecules comprised of three fatty acids. Triglycerides often impart appealing textures to foods like creaminess. However, triglycerides are not a taste stimulus. Fatty acids that are cleaved off the triglyceride in the food or during chewing in the mouth stimulate the sensation of fat. The taste component of fat is often described as bitter or sour because it is unpleasant, but new evidence reveals fatty acids evoke a unique sensation satisfying another element of the criteria for what constitutes a basic taste, just like sweet, sour, salty, bitter and umami.

Windows 10 Will Have Screen Recording Tool 203

Mark Wilson writes: Windows 10 has not even been released yet, but that's a perfect reason to start unearthing a few secrets. Over the coming weeks and months there will undoubtedly be an endless stream of tips, tricks, and tweaks to try out, but how's this for starters? Windows 10 has a secret screen recording tool that can be used to capture on-screen activity as a video file. Taking a static screenshot is very simple. You can either hit the Print Screen key, use the Snipping Tool, or turn to one of the countless screen capture tools out there — many of which are free. When it comes to capturing video, however, it's something of a different story. Before you splash out on a dedicated tool such as Camtasia, you might want to try out Windows 10's hidden tool. It's designed for gamers really, but anyone can use it. The Game bar is a toolbar which Microsoft meant for gamers to use to capture screenshots of their high scores, as well as video footage of their gaming skills. Despite the name, it is not limited to use within games

Internet Dating Scams Target Older American Women 176

HughPickens.com writes: The NYT reports: "Janet N. Cook, a church secretary in Virginia, had been a widow for a decade when she joined an Internet dating site and was quickly overcome by a rush of emails, phone calls and plans for a face-to-face visit. "I'm not stupid, but I was totally naïve," says Cook, now 76, who was swept off her feet by a man who called himself Kelvin Wells and described himself as a middle-aged German businessman looking for someone "confident" and "outspoken" to travel with him to places like Italy, his "dream destination." But very soon he began describing various troubles, including being hospitalized in Ghana, where he had gone on business, and asked Cook to bail him out. In all, she sent him nearly $300,000, as he apparently followed a well-honed script that online criminals use to bilk members of dating sites out of tens of millions of dollars a year."

According to the Times internet scammers are targeting women in their 50s and 60s, often retired and living alone, who say that the email and phone wooing forms a bond that may not be physical but that is intense and enveloping. Between July 1 and Dec. 31, 2014, nearly 6,000 people registered complaints of such confidence fraud with losses of $82.3 million, according to the federal Internet Crime Complaint Center. Older people are ideal targets because they often have accumulated savings over a lifetime, own their homes and are susceptible to being deceived by someone intent on fraud. The digital version of the romance con is now sufficiently widespread that AARP's Fraud Watch Network has urged online dating sites to institute more safeguards to protect against such fraud. The AARP network recommends that dating site members use Google's "search by image" to see if the suitor's picture appears on other sites with different names. If an email from "a potential suitor seems suspicious, cut and paste it into Google and see if the words pop up on any romance scam sites," the network advised. The website romancescams.org lists red flags to look for to identify such predators, who urgently appeal to victims for money to cover financial setbacks like unexpected fines, money lost to robbery or unpaid wages. Most victims say they are embarrassed to admit what happened, and they fear that revealing it will bring derision from their family and friends, who will question their judgment and even their ability to handle their own financial affairs."It makes me sound so stupid, but he would be calling me in the evening and at night. It felt so real. We had plans to go to the Bahamas and to Bermuda together," says Louise Brown. "When I found out it was a scam, I felt so betrayed. I kept it secret from my family for two years, but it's an awful thing to carry around. But later I sent him a message and said I forgave him."

Antineutrino Detectors Could Be Key To Monitoring Iran's Nuclear Program 79

agent elevator writes: Tech that analyzes antineutrinos might be the best way to keep tabs on Iran's nuclear program. The technology, which can tell how much of and what kind of plutonium and uranium are nearby, should be ready to serve as a nuclear safeguard in less than two years, according to IEEE Spectrum. In a simulation of the Arak nuclear plant, which the Iran deal requires be redesigned to make less plutonium, a detector parked outside in a shipping container could do the job.

Comment We need COMMUNISM NOW! (Score -1, Troll) 101

The world political situation as a whole is chiefly characterized by a historical crisis of the leadership of the proletariat.

The economic prerequisite for the proletarian revolution has already in general achieved the highest point of fruition that can be reached under capitalism. Mankind’s productive forces stagnate. Already new inventions and improvements fail to raise the level of material wealth. Conjunctural crises under the conditions of the social crisis of the whole capitalist system inflict ever heavier deprivations and sufferings upon the masses. Growing unemployment, in its turn, deepens the financial crisis of the state and undermines the unstable monetary systems. Democratic regimes, as well as fascist, stagger on from one bankruptcy to another.

The bourgeoisie itself sees no way out. In countries where it has already been forced to stake its last upon the card of fascism, it now toboggans with closed eyes toward an economic and military catastrophe. In the historically privileged countries, i.e., in those where the bourgeoisie can still for a certain period permit itself the luxury of democracy at the expense of national accumulations (Great Britain, France, United States, etc.), all of capital’s traditional parties are in a state of perplexity bordering on a paralysis of will.

The “New Deal,” despite its first period of pretentious resoluteness, represents but a special form of political perplexity, possible only in a country where the bourgeoisie succeeded in accumulating incalculable wealth. The present crisis, far from having run its full course, has already succeeded in showing that “New Deal” politics, like Popular Front politics in France, opens no new exit from the economic blind alley.

International relations present no better picture. Under the increasing tension of capitalist disintegration, imperialist antagonisms reach an impasse at the height of which separate clashes and bloody local disturbances (Ethiopia, Spain, the Far East, Central Europe) must inevitably coalesce into a conflagration of world dimensions. The bourgeoisie, of course, is aware of the mortal danger to its domination represented by a new war. But that class is now immeasurably less capable of averting war than on the eve of 1914.

All talk to the effect that historical conditions have not yet “ripened” for socialism is the product of ignorance or conscious deception. The objective prerequisites for the proletarian revolution have not only “ripened”; they have begun to get somewhat rotten. Without a socialist revolution, in the next historical period at that, a catastrophe threatens the whole culture of mankind. The turn is now to the proletariat, i.e., chiefly to its revolutionary vanguard. The historical crisis of mankind is reduced to the crisis of the revolutionary leadership.

Double-Dynamo Model Predicts 60% Fall In Solar Output In The 2030s 249

sycodon points out reports of a new model of solar dynamics from University of Northumbria professor Valentina Zharkova, predictions from which "suggest that solar activity will fall by 60 per cent during the 2030s to conditions last seen during the 'mini ice age' that began in 1645." Zharkova's model, based on observation of solar magnetism, "draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone." Zharkova’s and her colleages at three other universities believe that this two-layer model "could explain aspects of the solar cycle with much greater accuracy than before — possibly leading to enhanced predictions of future solar behaviour. “We found magnetic wave components appearing in pairs; originating in two different layers in the Sun’s interior. They both have a frequency of approximately 11 years, although this frequency is slightly different [for both] and they are offset in time.”

Well-Played: Microsoft Parlays NSF Video 'Remake' Into National CS K-12 Crisis 69

theodp writes: K–12 computer science and information technology teachers head to Grapevine, TX this week for the 2015 CSTA Conference. A glance at the draft agenda shows a remarkable number of presenters employed by or tied to two-year-old Code.org, the tech-bankrolled nonprofit that coincidentally sprung up together with Mark Zuckerberg's FWD.us PAC just months after Microsoft called for the creation of a national K-12 CS and tech immigration crisis to advance its agenda. Code.org's shaping of the nation's CS K-12 education began with the release of its tech-billionaire and celebrity-studded, slickly-produced What Most Schools Don't Teach video, which went viral on YouTube after being promoted by politicians, Facebook, Google, and a Microsoft-sponsored theatrical release, sparking a groundswell of interest in expanding K-12 CS education, succeeding where a similarly-themed-and-messaged but decidedly-amateurish National Science Foundation video of real-but-little-known computer scientists failed just months earlier (YouTube Doubler comparison).
