Scientists Create Smart Labels To Tell You When To Throw Away Expired Food and Makeup (sciencemag.org) 56

At the 254th National Meeting and Exposition of the American Chemical Society, researchers are presenting a low-cost, portable, paper-based sensor that can let you know when to toss food and cosmetics. The sensor can detect antioxidants in tea and wine, and be used to explore remote locations, such as the Amazon rainforest, in search of natural sources of antioxidants. "I've always been interested in developing technologies that are accessible to both industry and the general population," Silvana Andreescu, Ph.D., says. "My lab has built a versatile sensing platform that incorporates all the needed reagents for detection in a piece of paper. At the same time, it is adaptable to different targets, including food contaminants, antioxidants and free radicals that indicate spoilage." Phys.Org reports: What sets Andreescu's sensors apart from others, she says, are the nanostructures they use to catch and bind to compounds they're looking for. "Most people working on similar sensors use solutions that migrate on channels," Andreescu says. "We use stable, inorganic particles that are redox active. When they interact with the substances we want to detect, they change color, and the intensity of the change tells us how concentrated the analyte is." Additionally, because all of the reagents needed to operate the device are incorporated in the paper, users don't need to add anything other than the sample being tested. The American Chemical Society has published a video detailing the sensor. Their paper has been published in the journal Analyst.

Ask Slashdot: What Software (Or Hardware) Glitch Makes You Angry? 484

This question was inspired when Slashdot reader TheRealHocusLocus found their laptop "in the throes of a Windows 10 Update," where "progress has rolled past 100% several times and started over." I pushed the re-schedule dialogue to the rear and left it waiting. But my application did not count as activity and I left for a few moments, so Windows decided to answer its own question and restart (breaking a persistent Internet connection)... I've had it. Upon due consideration I now conclude I have been personally f*ck'd with. Driver availability, my apps and WINE permitting, this machine is getting Linux or pre-Windows-8...

That's mine, now let's hear about the things that are pushing you over the edge this very minute. Phones, software, power windows, anything.

There's a longer version of this story in the original submission -- but what's bugging you today? Leave your best answers in the comments. What software (or hardware glitch) makes you angry?

Staples Tries Co-Working Spaces To Court Millennials And Entrepreneurs (pilotonline.com) 177

Are there any Slashdot readers who are doing their work in co-working spaces? An anonymous reader writes: Staples office-supply stores is aggressively repositioning its brand to entice new customers like tech entrepreneurs and small businesses, reports The New York Times. "A case in point: Staples' partnership with Workbar, a Boston-based co-working company founded in 2009... Workbar attracts the coveted millennial generation, as well as entrepreneurs, a potential pipeline for new small business customers." Three co-working spaces have now been added to Staples stores, including their original flagship store in Boston, and the Times spotted funky art, skylights, an artificial putting green, as well as gourmet coffee "and -- on some nights -- happy hours with beer and wine."

"This blend of old and new shows how Staples Inc. is digging up its roots as one of the first, and most successful, big-box retailers. Under Shira Goodman, the company's new chief executive officer, Staples hopes it can reverse its years of declining sales, unlike so many other retailers left for dead in the internet age."

The company also reports online orders already make up 60% of their sales, which they hope to push to 80% by 2020, according to the Motley Fool. "Selling products, 50% of which are outside of traditional office supply categories, to businesses large and small has proven to be a resilient business for Staples."

Forget Apple. Xiaomi CEO Now Wants to Be More Like Costco (bloomberg.com) 33

Xiaomi says it's misunderstood. Once compared with Apple for its sleek smartphones and charismatic leadership, the Chinese startup is seeking an image makeover as it tries to recover from a sales-growth slide. From a report: And the brand its billionaire co-founder Lei Jun wants to be compared with: Costco Wholesale Corp., the Issaquah, Washington-based warehouse retailer that sells everything from wine and diamond rings to bulging boxes of cereal and fruit at knockdown prices. Xiaomi's revenue will probably reach $15 billion this year as the Beijing-based maker of products ranging from pens and air purifiers to TVs and smartphones adopts a new business model and fine-tunes operations, Lei, 47, said in a recent interview. "We are not Apple," Lei, clad in a black polo shirt and blue jeans, said at Xiaomi's Bengaluru office in India, its biggest overseas market. "We have the same value system as Costco. We want users to enjoy better products at an affordable price."

Ask Slashdot: Can Linux Run a GPU-Computing Application Written For Windows? 117

dryriver writes: I have been told that Linux can run Windows software using Wine or perhaps a VM. What happens if that Windows software is a GPU-computing application -- accessing the GPU through HLSL/GLSL/CUDA/OpenCL or similar interfaces? Can Wine or other solutions run that software at a decent speed under Linux? Or is GPU-computing software written for the Windows platform unsuitable for use -- emulated or otherwise -- under Linux? This sounds like one of those cases where there's a theoretical answer and then your own real-world experiences. So leave your best answers in the comments. Can Linux run a GPU-computing application that's written for Windows?

Alcohol Is Good for Your Heart -- Most of the Time (time.com) 125

Alcohol, in moderation, has a reputation for being healthy for the heart. Drinking about a glass of wine for women per day, and two glasses for men, is linked to a lower risk of heart attack, stroke and death from heart disease. From a report on Time: A new study of nearly two million people published in The BMJ adds more evidence that moderate amounts of alcohol appear to be healthy for most heart conditions -- but not all of them. The researchers analyzed the link between alcohol consumption and 12 different heart ailments in a large group of U.K. adults. None of the people in the study had cardiovascular disease when the study started. People who did not drink had an increased risk for eight of the heart ailments, ranging from 12 percent to 56 percent, compared to people who drank in moderation. These eight conditions include the most common heart events, such as heart attack, stroke and sudden heart-related death.

It's Possible To Hack a Smartphone With Sound Waves, Researchers Show (cnbc.com) 41

A security loophole that would allow someone to add extra steps to the counter on your Fitbit monitor might seem harmless. But researchers say it points to the broader risks that come with technology's embedding into the nooks of our lives. John Markoff, writes for the NYTimes: On Tuesday, a group of computer security researchers at the University of Michigan and the University of South Carolina will demonstrate that they have found a vulnerability that allows them to take control of or surreptitiously influence devices through the tiny accelerometers that are standard components in consumer products like smartphones, fitness monitors and even automobiles. In their paper, the researchers describe how they added fake steps to a Fitbit fitness monitor and played a "malicious" music file from the speaker of a smartphone to control the phone's accelerometer. That allowed them to interfere with software that relies on the smartphone, like an app used to pilot a radio-controlled toy car. "It's like the opera singer who hits the note to break a wine glass, only in our case, we can spell out words" and enter commands rather than just shut down the phone, said Kevin Fu, an author of the paper, who is also an associate professor of electrical engineering and computer science at the University of Michigan and the chief executive of Virta Labs, a company that focuses on cybersecurity in health care. "You can think of it as a musical virus."

Alcohol Switches the Brain Into Starvation Mode In Mice, Increasing Hunger and Appetite, Study Finds (bbc.com) 130

An anonymous reader quotes a report from BBC: In tests on mice, alcohol activated the brain signals that tell the body to eat more food. The UK researchers, who report their findings in the journal Nature Communications, believe the same is probably true in humans. The mice were given generous doses of alcohol for three days -- a dose being equivalent to around 18 units or a bottle-and-a-half of wine for a person. The alcohol caused increased activity in neurons called AGRP. These are the neurons that are fired when the body experiences starvation. The mice ate more than normal too. When the researchers repeated the experiment but blocked the neurons with a drug, the mice did not eat as much which, the researchers say, suggests that AGRP neurons are responsible for the alcohol-induced eating. The study authors, Denis Burdakov and colleagues, say understanding how alcohol changes the body and our behavior could help with managing obesity. Around two-thirds of adults in the UK are overweight or obese.

ReactOS 0.4.2 Released: Supports Linux Filesystems, .NET Applications, and Doom 3 (reactos.org) 145

Continuing its rapid release cycle, ReactOS has unveiled version 0.4.2 of its free "open-source binary-compatible Windows re-implementation." Slashdot reader jeditobe reports that this new version can now read and write various Linux/Unix file systems like Btrfs and ext (and can read ReiserFS and UFS), and also runs applications like Thunderbird and 7-Zip. ReactOS 0.4.2 also features Cygwin support, .NET 2.0 and 4.0 application support, among other updated packages and revised external dependencies such as Wine and UniATA. The team also worked to improve overall user experience...

ReactOS is free. You can boot your desktop or laptop from it. It looks like Windows (a 10-year-old version, anyway), so you already know how to use it. And it'll run some Windows and DOS applications, maybe including DOS games that regular 64-bit Windows can no longer touch.
These videos even show ReactOS running Elder Scrolls: Skyrim and Doom 3.

McDonald's 'Make Burger History' Site Hijacked With Offensive Burger Ideas (stuff.co.nz) 192

An anonymous reader quotes a report from Stuff.co.nz: McDonald's New Zealand has been left with egg on its face after a raft of bad-taste burger suggestions customers forced it to quickly take down its new design-your-own-burger website. The company launched its "Make Burger History" site this week, as part of a new promotion where customers can "build your own unique burger" and get free fries and a medium soft drink. "Just come in to a participating 'Create Your Taste' McDonald's and order your Creation at the self ordering kiosk," McDonald's promised. But its failure to consider what pranksters might dream up online has left the company red-faced, with the website overrun by racist, homophobic and otherwise offensive suggestions. The page now redirects to the McDonald's homepage. The burger concepts ranged from the mild, such as "Bag of Lettuce" (literally just a pile of lettuce leaves) and "The Carbonator" (seven burger buns, no filling), to X-rated, including "Girth" (a stack of seven undressed burger patties) and "Ron's Creamy Surprise" (a pile of mayonnaise, best left unexplained). But many went totally tasteless, creating burgers with names like "Mosque at Ground-Zero," "Rektal Prolapse" and "Toddler Body Bag," some of which ended up on the website's front page before it was shut down entirely overnight.

Intel ChromeBooks Can Now Run Wine and Steam (codeweavers.com) 45

"With Google Play and Android app support hitting Chromebooks, it's now possible to run Windows applications/games on Chromebooks via CrossOver For Android," reports Phoronix. Slashdot reader grungy writes: The first Intel ChromeBooks have access to the Play Store now, and the Android version of Wine apparently runs on them... Pictures show the Steam client running, and a clip of a D3D game. Of course, the Play Store is only available on the ChromeOS developer channel so far, but that should change later this year.
CrossOver for Android also hasn't been officially released, but Thursday CodeWeavers' president blogged excitedly that "we are staring at a Leprechaun riding on the back of a Unicorn while taking a picture of a UFO. We are running CrossOver through Android on a ChromeBook running a Windows based game launched from the Steam client. THIS HAS NEVER BEEN DONE BEFORE...EVER!!!"

Researchers Develop Electronic Nose To Sniff Out Pesticides and Nerve Gas (phys.org) 23

An anonymous reader quotes a report from Phys.Org: Researchers from KU Leuven have now built a very sensitive electronic nose with metal-organic frameworks (MOFs). "MOFs are like microscopic sponges," postdoctoral researcher Ivo Stassen explains. "They can absorb quite a lot of gas into their minuscule pores." "We created a MOF that absorbs the phosphonates found in pesticides and nerve gases. This means you can use it to find traces of chemical weapons such as sarin or to identify the residue of pesticides on food. This MOF is the most sensitive gas sensor to date for these dangerous substances. Our measurements were conducted in cooperation with imec, the Leuven-based nanotechnology research centre. The concentrations we're dealing with are extremely low: parts per billion -- a drop of water in an Olympic swimming pool -- and parts per trillion." The chemical sensor can easily be integrated into existing electronic devices, Professor Rob Ameloot adds. "You can apply the MOF as a thin film over the surface of, for instance, an electric circuit. Therefore, it's fairly easy to equip a smartphone with a gas sensor for pesticides and nerve gas." Professor Ameloot continues, "MOFs can measure very low concentrations, so we could use them to screen someone's breath for diseases such as lung cancer and MS in an early stage. Or we could use the signature scent of a product to find out whether food has gone bad or to distinguish imitation wine from the original. This technology, in other words, offers a wide range of perspectives."

Estonian President Expresses Desire For More Digitally-Integrated Europe (arstechnica.com) 64

In a wide-ranging interview with Ars Technica, Estonian President Toomas Hendrik talked about European Digital Single Market (DSM), an ambitious goal that seeks to make commerce flow as smoothly across the 28-member block as it does in the United States. He cites the example of iTunes. From the report: What Estonia and Finland are doing is a step towards the DSM -- but there remain all kinds of national-level laws that stop Europe from being truly unified. "Take iTunes," President Ilves continued. "iTunes are based on credit cards. Credit cards are national. I cannot buy an iTunes record for my wife who has a Latvian credit card. I cannot buy her an iTunes record because I have an Estonian iTunes. This is true of virtually everything that is connected to digital services. And certainly this is why Estonia is at the forefront of the European Digital Single Market. As I like to say, it's easier to ship a bottle of Portuguese wine from southern Portugal in the Algarve and sell it in northern Lapland, than it is for me to buy an iTunes record across the Estonian-Latvian border."The report is worth a read in its entirety.

Wine Makes It Possible To Run Vulkan Windows Programs On Linux (phoronix.com) 52

The cool Wine-related news of the week isn't just for Android Remix; an anonymous reader writes with some news applicable to a wider set of users: While no Windows-only Vulkan games have yet to be released, Wine developers are ready and have worked out experimental support for wrapping Vulkan Windows programs on Linux. Assuming you have a Vulkan Linux driver, the latest Wine-Staging build allows for Vulkan Windows programs/games to be dynanically translated and run on Linux 32-bit and 64-bit. Wine's Vulkan wrapper is passing all Khronos conformance tests, but hopefully the ever-expanding Linux game catalog will make this 10k+ lines of code not necessary moving into the future.

ReactOS 0.4 Brings Open Source Windows Closer To Reality (techrepublic.com) 141

jeditobe was one of several readers to point out the newest major release of Windows NT-inspired ReactOS, which has just hit version 0.4, brings open source Windows compatibility a little bit closer. The new release includes out-of-the-box support for ext2, ext3, and ext4, as well as (remember, it is NT based) read-only support for NTFS. What else? Support was generally improved for third-party device drivers, making it substantially easier to install and use real hardware, as opposed to just virtual machines like VirtualBox. The internal WINE library was updated to improve support for Win32 programs. Support for Python 2.7 was added, making it possible to use python scripts in ReactOS. A substantial number of visual changes were added, with a vastly improved shell and file explorer, newer icons throughout ReactOS, improved support for fonts, and customizable visual themes. Even with these improvements, ReactOS 0.4 is still generally considered alpha-level software, though Alexander Rechitskiy, the innovation manager for ReactOS, notes that 0.4.1 may be almost beta-level software.

Explaining the Lack of Quality Journalism In the Internet Age (gawker.com) 311

schnell writes: While many lament the seeming lack of quality, in-depth journalism today, a Gawker article argues that the inescapable problem is that you need a paying (in some form) audience (of a large enough size) to do it. There are plenty of free "news" sources to be found online, especially blogs simply regurgitating and putting a spin on wire news reports. But as the article notes, "The audience for quality prestige content is small. Even smaller than the actual output of quality prestige content, which itself is smaller than most media outlets like to imagine." Even highly respected news sources like the New York Times are resorting to wine clubs, and the Washington Post is giving free subscriptions to Amazon Prime members to drive more corporate synergy and revenue. Rich parent companies are giving up on boutique, high-quality, niche journalism projects like ESPN's Grantland and Al Jazeera America because there simply aren't enough TV viewers/online ad clickers to pay the bills. So how do we reconcile our collectively-stated desire for high quality journalism with our (seeming) collective unwillingness to pay for it?
