600,000 TFTP Servers Can Be Abused For Reflection DDoS Attacks

An anonymous reader writes: Researchers have discovered that improperly configured TFTP servers can be easily abused to carry out reflection DDoS attacks that can sometimes have an amplification factor of 60, one of the highest such values. There are currently around 600, 000 TFTP servers exposed online, presenting a huge attack surface for DDoS malware developers. Other protocols recently discovered as susceptible to reflection DDoS attacks include DNSSEC, NetBIOS, and some of the BitTorrent protocols. Read more of this story at Slashdot.

No More Public Access To Google PageRank Scores

campuscodi writes: Google has confirmed with Search Engine Land that it is removing PageRank scores from the Google toolbar, which was the last place where someone could check their site’s PageRank status. Many SEO experts are extremely happy at this point, since it seems that PageRank is responsible for all the SEO spam we see today. Read more of this story at Slashdot.

Google Building a 100kW Transmitter at Spaceport America

szczys writes: Google is building a 100kW transmitter at Spaceport America. As is becoming the regular source of early info, this comes via an FCC filing in which Google has asked the agency to keep the project secret. The signal strength itself isn’t [groundbreaking] until you learn this is a directional antenna. Some of the most powerful FM radio transmitters get to 100kW, but those are omnidirectional. This is a highly focused directional antenna and that makes it sound like a big piece of Google’s hushed Broadband Drone program. Read more of this story at Slashdot.

Bitcoin’s Nightmare Scenario Has Come To Pass

HughPickens.com writes: Ben Popper writes at The Verge that bitcoin’s nightmare scenario has come to pass as the bitcoin network reached its capacity, causing transactions around the world to be massively delayed, and in some cases to fail completely. The average time to confirm a transaction has ballooned from 10 minutes to 43 minutes. Users are left confused and shops that once accepted Bitcoin are dropping out. For those who want the Bitcoin system to continue to grow and thrive, this is troubling. Merchants can’t rely on digital transactions that can take minutes or hours to validate. A number of prominent voices in the Bitcoin community have been warning over the past year that the system needed to make fundamental changes to its core software code to avoid being overwhelmed by the continued growth of Bitcoin transactions. A schism has developed between the team in charge of the original codebase for Bitcoin, known as Core, and a rival faction pushing its own version of that open source code with a block size increase added in, known as Classic. “Many in the US Bitcoin community had hoped that hitting this crisis point — a network maxed out, transactions faltering — would result in closure, with miners quickly moving to adopt whichever chain proved more valuable to their economic interests, ” says Popper. “But so far the debate is dragging on without one side claiming a clear victory, leaving tens of thousands of consumer transactions stranded in limbo.” Read more of this story at Slashdot.

Scientists May Have Found Molecular Gatekeeper Of Long-Term Memory

hackingbear writes: While the general steps of forming a long-term memory are clear, the details, such as how exactly the molecular signals get shuttled to the command center, which generally has tight security, are unclear. A new study, led by neuroscientist Yi Zhong of Tsinghua University in Beijing, may finally have that answer. In the tiny minds of fruit flies, a protein called importin-7 acts to shuttle the memory-triggering signal into the nucleus with its top-level clearance to the restricted area, researchers report in the Proceedings of the National Academy of Sciences. With genetic tweaking, the researchers dialed up and down the amount of importin-7 in the flies and then put them through the memory training and test. They found that cranking up levels of the shuttle protein strengthened the long-term memories of the flies, while turning it off weakened their memory. “The current work confirms that [importin-7] is indeed critical at the behavioral level in mediating [long-term memory] consolidation, ” the authors concluded.

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.

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.

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.

‘Moth Eye’ Graphene Breakthrough Could Create Indoor Solar Cells

A scientific breakthrough with the “wonder material” graphene has opened up the possibility of indoor solar cells that capture energy from indirect sunlight, as well as ambient energy from household devices. Researchers from the University of Surrey in the U.K. studied the eyes of moths to create sheets of graphene that they claim is the most light-absorbent material ever created. “We realized that the moth’s eye works in a particular way that traps electromagnetic waves very efficiently, ” Professor Ravi Silva, head of the Advanced Technology Institute at the University of Surrey, tells Newsweek. “As a result of our studies, we’ve been able to mimic the surface of a moth’s eye and create an amazingly thin, efficient, light-absorbent material made of graphene.” Read more of this story at Slashdot.
