Israeli Troops Who Relied On Waze Blundered Into Deadly Palestinian Firefight

An anonymous reader writes: Israeli forces mounted a rescue mission in a Palestinian neighborhood after gun battles erupted when two soldiers mistakenly entered the area because of an error on a satellite navigation app, Israeli authorities said Tuesday.The clashes late Monday in the Qalandiya refugee camp outside Jerusalem left at least one Palestinian dead and 10 injured, one seriously. According to initial Israeli reports, the two soldiers said they had been using Waze, a highly touted Israeli-invented navigation app bought more than two years ago by Google. The smartphone app, which has a settings option to ‘avoid dangerous areas, ‘ relies on crowdsourcing to give users the fastest traffic routes. Read more of this story at Slashdot.

Google-Backed SSD Endurance Research Shows MLC Flash As Reliable As SLC

MojoKid writes: Even for mainstream users, it’s easy to feel the differences between using a PC that has an OS installed on a solid state drive versus a mechanical hard drive. Also, with SSD pricing where it is right now, it’s also easy to justify including one in a new configuration for the speed boost. And there’s obvious benefit in the enterprise and data center for both performance and durability. As you might expect, Google has chewed through a healthy pile of SSDs in its data centers over the years and the company appears to have been one of the first to deploy SSDs in production at scale. New research results Google is sharing via a joint research project now encompasses SSD use over a six year span at one of Google’s data centers. Looking over the results led to some expected and unexpected findings. One of the biggest discoveries is that SLC-based SSDs are not necessarily more reliable than MLC-based drives. This is surprising, as SLC SSDs carry a price premium with the promise of higher durability (specifically in write operations) as one of their selling points. It will come as no surprise that there are trade-offs of both SSDs and mechanical drives, but ultimately, the benefits SSDs offer often far outweigh the benefits of mechanical HDDs.

Scientists Achieve Perfect Efficiency For Water-Splitting Half-Reaction

Dthief writes: Splitting water is a two-step process, and in a new study, researchers have performed one of these steps (reduction) with 100% efficiency. The results shatter the previous record of 60% for hydrogen production with visible light, and emphasize that future research should focus on the other step (oxidation) in order to realize practical overall water splitting. The main application of splitting water into its components of oxygen and hydrogen is that the hydrogen can then be used to deliver energy to fuel cells for powering vehicles and electronic devices. The process involves exposing the water to a mass of platinum-tipped nanorods, with visible light driving the reaction. The 100% efficiency refers to the photon-to-hydrogen conversion efficiency, and it means that virtually all of the photons that reach the photocatalyst generate an electron, and every two electrons produce one H2 molecule. At 100% yield, the half-reaction produces about 100 H2 molecules per second (or one every 10 milliseconds) on each nanorod, and a typical sample contains about 600 trillion nanorods.

As of Tonight, 1900 Steam Games For Linux

New submitter KGIII writes: “After a recent Steam change, there were more than 1, 900 Steam Linux games listed as Valve ended up including yet-to-be-released Linux game ports. That total including unreleased Linux games is now up to 2, 009! But in terms of released Linux game titles available for download right now, the 1, 900 threshold was crossed tonight to end out February.” It’s getting there. All of you gamers might just be able to make the choice to move to Linux soon. It looks like there are quite a few more games coming down the pipe. This is a good thing as it gives gamers more options for their operating system. I imagine this bodes well for the SteamOS project and for the dedicated SteamOS devices.

CompuLab Rolls out Fanless, High-End PCs With Unique Design

An anonymous reader writes: Israeli PC maker CompuLab has begun shipping the Airtop PC that allows assembling high-end PC components into a completely fanless design. Phoronix’s initial testing of the Airtop PC showed that it has a Core i7 5775C Broadwell processor, 16GB of RAM, 256GB SSD, and GeForce GTX 950 all while being fan-less thanks to the innovative design. The early results are quite positive for this uniquely designed PC but it comes at a cost premium of a fully-loaded system costing more than $2, 200 USD. Read more of this story at Slashdot.

Giant Viruses Feature Their Own Built-In Antivirus Software

Mimiviruses are viruses so big they can actually be seen with the naked eye. European scientists have now learned that these bizarre organisms have their own immune system that makes them virtually invulnerable to predatory viruses, suggesting these creatures may actually represent a new branch in the tree of life.

Chinese ISPs Caught Injecting Ads And Malware In Their Network Traffic

Chinese Internet Service Providers (ISPs) have been caught red-handed for injecting advertisements as well as malware through their network traffic. Three Israeli researchers uncovered that the major Chinese-based ISPs named China Telecom and China Unicom, two of Asia’s largest network operators, have been engaged in an illegal practice of content injection in network traffic. Chinese ISPs had set up many proxy servers to pollute the client’s network traffic not only with insignificant advertisements but also malware links, in some cases, inside the websites they visit. If an Internet user tries to access a domain that resides under these Chinese ISPs, the forged packet redirects the user’s browser to parse the rogue network routes. As a result, the client’s legitimate traffic will be redirected to malicious sites/ads, benefiting the ISPs. Read more of this story at Slashdot.

Are CEOs Overpaid? Not Compared With College Presidents

schwit1 writes: For outrageous executive earnings, don’t look to Wall Street — look to academia. High pay for CEOs attracts annual attention and recitations about the immorality of capitalism, but when the focus is on average CEO pay, they make less than half the annual earnings of college presidents, according to CBS News. The average CEO earns $176, 840 annually, an amount that would make a university president into a pauper. In academia, college presidents earn $377, 261 annually. Americans outraged and indebted by high college costs will be quick to draw the parallel between a college president’s pay and their tuition bill. Correlation, though, doesn’t imply causation. College presidents aren’t always the highest-paid college employees — athletic coaches often earn more. Regardless, college presidents “are well into the 99th percentile of compensation for wage earners in the United States, ” Peter L. Hinrichs and Anne Chen noted for the Federal Reserve Bank of Cleveland. Read more of this story at Slashdot.
