Submission + - Superhydrophobic nano-wallpaint in San Francisco pisses back on public pissers 2->

monkeyzoo writes: San Francisco is testing an ultra-water-repellant paint on wallls in areas fraught with public urination problems. The paint is designed to repel the urine and soil the pisser's pants. "It's supposed to, when people urinate, bounce back and hit them on the pants and get them wet. Hopefully that will discourage them. We will put a sign to give them a heads up," said Mohammad Nuru, director of the San Francisco public works. A Florida company named Ultra-Tech produces the super-hydrophobic oleophobic nano-coating that was also recently used with success on walls in Hamburg, Germany [video] to discourage public urination. Signs posted there warn, "Do not pee here! We pee back!" Time will tell if this works better than the firehose employed in India.

Replacing Silicon With Gallium Nitride In Chips Could Reduce Energy Use By 20% 90 90

Mickeycaskill writes: Cambridge Electronics Inc (CEI), formed of researchers from the Massachusetts Institute of Technology (MIT), claim semiconductors made of gallium nitride (GaN) could reduce the power consumption of data centers and consumer electronics by 20 percent by 2025. CEI has revealed a range of GaN transistors and power electronic circuits that have just one tenth of the resistance of silicon, resulting in much higher energy efficiency. The company claims to have overcome previous barriers to adoption such as safety concerns and expense through new manufacturing techniques. "Basically, we are fabricating our advanced GaN transistors and circuits in conventional silicon foundries, at the cost of silicon. The cost is the same, but the performance of the new devices is 100 times better," Cambridge Electronics researcher Bin Lu said.

Ask Slashdot: Why Is the Caps Lock Key Still So Prominent On Keyboards? 659 659

Esther Schindler writes: The developers at .io are into tracking things, I guess. In any case, a few weeks back they decided to track team performance in terms of keyboard and mouse activity during the working day. They installed a simple Chrome plugin on every Macbook and collected some statistics. For instance, developers have fewer keypresses than editors and managers—around 4k every day. Managers type more than 23k characters per day. And so on. Some pretty neat statistics.

But the piece that jumped out at me was this: "What's curious—the least popular keys are Capslock and Right Mouse Button. Somewhere around 0.1% of all keypresses together. It's time to make some changes to keyboards." I've been whining about this for years. Why is it that the least-used key on my keyboard is not just in a prominent position, but also bigger than most other keys? I can I invest in a real alternate keyboard with a different layout (my husband's a big fan of the Kinesis keyboards, initially to cope with carpal tunnel). But surely it's time to re-visit the standard key layout? What keys would you eliminate or re-arrange?

Sprked Tries To Solve Valve's Paid Mods Scandal 37 37

SlappingOysters writes: This article takes a closer look at the emerging crowdfunding platform Sprked, which aims to follow the Patreon support model, but exclusively for video game modders. The service is currently in its early stages, but by crafting a system of appreciation and support that acknowledges the loyalty of the modding community, Sprked has the potential to promote and foster the creativity that is so integral to modding, instead of hampering it with the murky baggage of a mandatory economy. Valve's attempt to let modders make some money for their efforts backfired within the community — there are four demons the paid mods plan must slay to actually work.

Submission + - OPM hackers suspected in United Airlines breach->

vivaoporto writes: Bloomberg reports that the hackers who stole data on more than 22 million U.S. insurance holders and government employees in recent months breached another big target at around the same time — United Airlines.

United, the world's second-largest airline, detected an incursion into its computer systems in May or early June, said several people familiar with the probe. According to three of these people, investigators working with the carrier have linked the attack to a group of China-backed hackers they say are behind several other large heists — including the theft of security-clearance records from the U.S. Office of Personnel Management and medical data from health insurer Anthem Inc.

The airline is still trying to determine exactly which data was removed from the network, said two of the people familiar with the probe. That assessment took months in the OPM case, which was discovered in April and made public in June.

Besides passenger lists and other flight-related data, the hackers may also have taken information related to United’s mergers and acquisitions strategy, one of the people familiar with the investigation said.

Flight manifests usually contain the names and birthdates of passengers, but even if those files were taken, experts say that would be unlikely to trigger disclosure requirements in any of the 47 states with breach-notification laws.

The timing of the United breach also raises questions about whether it's linked to computer faults that stranded thousands of the airline's passengers in two incidents over the past couple of months. Two additional people close to the probe, who like the others asked not to be identified when discussing the investigation, say the carrier has found no connection between the hack and a July 8 systems failure that halted flights for two hours. They didn't rule out a possible, tangential connection to an outage on June 2.

Maliciously Crafted MKV Video Files Can Be Used To Crash Android Phones 90 90

itwbennett writes: Just days after publication of a flaw in Android's Stagefright, which could allow attackers to compromise devices with a simple MMS message, researchers have found another Android media processing flaw. The latest vulnerability is located in Android's mediaserver component, more specifically in how the service handles files that use the Matroska video container (MKV), Trend Micro researchers said. "When the process opens a malformed MKV file, the service may crash (and with it, the rest of the operating system). The vulnerability is caused by an integer overflow when the mediaserver service parses an MKV file. It reads memory out of buffer or writes data to NULL address when parsing audio data."

Kentucky Man Arrested After Shooting Down Drone 1130 1130

McGruber writes: Hillview, Kentucky resident William H. Merideth describes his weekend: "Sunday afternoon, the kids – my girls – were out on the back deck, and the neighbors were out in their yard. And they come in and said, 'Dad, there's a drone out here, flying over everybody's yard.'" Merideth's neighbors saw it too. "It was just hovering above our house and it stayed for a few moments and then she finally waved and it took off," said neighbor Kim VanMeter. Merideth grabbed his shotgun and waited to see if the drone crossed over his property. When it did, he took aim and shot it out of the sky.

The owners showed up shortly, and the police right after. He was arrested and charged with first degree criminal mischief and first degree wanton endangerment before being released the next day. Merideth says he will pursue legal action against the drone's owner: "He didn't just fly over. If he had been moving and just kept moving, that would have been one thing -- but when he come directly over our heads, and just hovered there, I felt like I had the right. You know, when you're in your own property, within a six-foot privacy fence, you have the expectation of privacy. We don't know if he was looking at the girls. We don't know if he was looking for something to steal. To me, it was the same as trespassing."

Submission + - Kentucky Man shoots drone that was hovering over sunbathing 16-year old girl->

McGruber writes: Hillview, Kentucky resident William H. Merideth describes his Sunday afternoon: "Sunday afternoon, the kids – my girls – were out on the back deck, and the neighbors were out in their yard," Merideth said. "And they come in and said, 'Dad, there’s a drone out here, flying over everybody’s yard.'"

Merideth's neighbors saw it too. "It was just hovering above our house and it stayed for a few moments and then she finally waved and it took off," said neighbor Kim VanMeter. VanMeter has a 16-year-old daughter who lays out at their pool. She says a drone hovering with a camera is creepy and weird. "I just think you should have privacy in your own backyard," she said.

Merideth agrees and said he had to go see for himself. “Well, I came out and it was down by the neighbor’s house, about 10 feet off the ground, looking under their canopy that they’ve got under their back yard," Merideth said. "I went and got my shotgun and I said, ‘I’m not going to do anything unless it’s directly over my property.’"

That moment soon arrived, he said. "Within a minute or so, here it came," he said. "It was hovering over top of my property, and I shot it out of the sky. I didn't shoot across the road, I didn't shoot across my neighbor's fences, I shot directly into the air."

It wasn't long before the drone's owners appeared. "Four guys came over to confront me about it, and I happened to be armed, so that changed their minds," Merideth said. "They asked me, 'Are you the S-O-B that shot my drone?' and I said, 'Yes I am,'" he said. "I had my 40mm Glock on me and they started toward me and I told them, 'If you cross my sidewalk, there's gonna be another shooting.'"

A short time later, Merideth said the police arrived. "There were some words exchanged there about my weapon, and I was open carry – it was completely legal," he said. "Long story short, after that, they took me to jail for wanton endangerment first degree and criminal mischief...because I fired the shotgun into the air."

Hacking a 'Smart' Sniper Rifle 68 68

An anonymous reader writes: It was inevitable: as soon as we heard about computer-aimed rifles, we knew somebody would find a way to compromise their security. At the upcoming Black Hat security conference, researchers Runa Sandvik and Michael Auger will present their techniques for doing just that. "Their tricks can change variables in the scope's calculations that make the rifle inexplicably miss its target, permanently disable the scope's computer, or even prevent the gun from firing." In one demonstration they were able to tweak the rifle's ballistic calculations by making it think a piece of ammunition weighed 72 lbs instead of 0.4 ounces. After changing this value, the gun tried to automatically adjust for the weight, and shot significantly to the left. Fortunately, they couldn't find a way to make the gun fire without physically pulling the trigger.

Newfound Bacteria Expand Tree of Life 27 27

An anonymous reader writes: It used to be that to find new forms of life, all you had to do was take a walk in the woods. Now it's not so simple. The most conspicuous organisms have long since been cataloged and fixed on the tree of life, and the ones that remain undiscovered don't give themselves up easily. You could spend all day by the same watering hole with the best scientific instruments and come up with nothing. Maybe it's not surprising, then, that when discoveries do occur, they sometimes come in torrents. Find a different way of looking, and novel forms of life appear everywhere. A team of microbiologists based at the University of California, Berkeley, recently figured out one such new way of detecting life. At a stroke, their work expanded the number of known types — or phyla — of bacteria by nearly 50 percent, a dramatic change that indicates just how many forms of life on earth have escaped our notice so far.

Windows 10 Launches 311 311

An anonymous reader writes: Today Microsoft officially released Windows 10 in 190 countries as a free upgrade for anyone with Windows 7 or later. Major features include Continuum (which brings back the start menu and lets you switch between a keyboard/mouse UI and a touch UI without forcing you into one or the other), the Cortana digital assistant, the Edge browser, virtual desktops, DirectX 12 support, universal apps, an Xbox app, and security improvements. Reviews of the operating system generally consider it an improvement over Windows 8.1, despite launch-day bugs. Peter Bright writes, "Windows 8 felt unfinished, but it was an unfinished thought. ... Windows 10 feels unfinished, but in a different way. The concept of the operating system is a great deal better than its predecessor. It's better in fact than all of its predecessors. ... For all my gripes, it's the right idea, and it's implemented in more or less the right way. But I think it's also buggier than Windows 8.1, 8, 7, or Vista were on their respective launch days." Tom Warren draws similar conclusions: "During my testing on a variety of hardware, I've run into a lot of bugs and issues — even with the version that will be released to consumers on launch day. ... Everything about Windows 10 feels like a new approach for Microsoft, and I'm confident these early bugs and issues will be addressed fairly quickly."

US Military Stepping Up Use of Directed Energy Weapons 83 83

An anonymous reader writes: At a conference on Tuesday, U.S. officials explained that all branches of the military would be increasing their use of lasers and other directed energy weapons. Lieutenant General William Etter said, "Directed energy brings the dawn of an entirely new era in defense." The Navy's laser deployment test has gone well, and they're working on a new prototype laser in the 100-150 kilowatt range. "[Navy Secretary Ray] Mabus said Iran and other countries were already using lasers to target ships and commercial airliners, and the U.S. military needed to accelerate often cumbersome acquisition processes to ensure that it stayed ahead of potential foes."
