> AvGas is typically only in the 105-120 range, and it's used in turbine engines with compression levels that would reduce a car's ICE to shrapnel.

No. Standard avgas is 100LL (100 Octane, low lead). It's just like gasoline from the auto pumps, but the octane level is higher and there's still some lead in it, where the auto industry is fully unleaded. (There are some aircraft that can handle lower-octane mogas, but they're rare.)

Turbine engines typically use Jet-A, which is a diesel-like, kerosene based fuel.

SSD Annual Failure Rates Around 1.5%, HDDs About 5% 512

Lucas123 writes "On the news that Linus Torvalds's SSD went belly up while he was coding the 3.12 kernel, Computerworld took a closer look at SSDs and their failure rates. While Torvalds didn't specify the SSD manufacturer in his blog, he did write in a 2008 blog that he'd purchased an 80GB Intel SSD — likely the X25, which has become something of an industry standard for SSD reliability. While they may have no mechanical parts, making them preferable for mobile use, there are many factors that go into an SSD being reliable. For example, a NAND die, the SSD controller, capacitors, or other passive components can — and do — slowly wear out or fail entirely. As an investigation into SSD reliability performed by Tom's Hardware noted: 'We know that SSDs still fail.... All it takes is 10 minutes of flipping through customer reviews on Newegg's listings.' Yet, according to IHS, client SSD annual failure rates under warranty tend to be around 1.5%, while HDDs are near 5%. So SSDs not only outperform, but on average outlast spinning disks."

Emscripten and New Javascript Engine Bring Unreal Engine To Firefox 124

MojoKid writes "There's no doubt that gaming on the Web has improved dramatically in recent years, but Mozilla believes it has developed new technology that will deliver a big leap in what browser-based gaming can become. The company developed a highly-optimized version of Javascript that's designed to 'supercharge' a game's code to deliver near-native performance. And now that innovation has enabled Mozilla to bring Epic's Unreal Engine 3 to the browser. As a sort of proof of concept, Mozilla debuted this BananaBread game demo that was built using WebGL, Emscripten, and the new JavaScript version called 'asm.js.' Mozilla says that it's working with the likes of EA, Disney, and ZeptoLab to optimize games for the mobile Web, as well." Emscripten was previously used to port Doom to the browser.

While I agree mostly with what you've said, keep in mind that, as a contractor, he's been asked to provide a different service, to train the new guy, and is being compensated as both parties deem appropriate. I completely agree that the submitter shouldn't work for free, but if he's amicable to this agreement (as he appears to be) then there's no reason he can't continue. He's made his objections about hiring a newbie to do it, but it's their code to do with as they please.

Ukrainian Attack Dolphins Are On the Loose 99

Hugh Pickens writes "The Ukrainian Navy has a small problem on their hands. The Atlantic reports that, after rebooting the Soviet Union's marine mammal program last year with the goal of teaching dolphins to find underwater mines and kill enemy divers, three of the Ukrainian military's new recruits have gone AWOL. Apparently they swam away from their trainers ostensibly in search of a 'mate' out in open waters. It might not be such a big deal except that these dolphins have been trained to 'attack enemy combat swimmers using special knives or pistols fixed to their heads.' Dolphins were trained at Sevastopol for the Soviet Navy as far back as 1973 to find military equipment such as sea mines on the seabed as well as attacking divers and even carrying explosives on their heads to plant on enemy ships. The U.S. has its own dolphin program in San Diego with 40 trained dolphins and sea lions and another 50 in training. U.S. Navy dolphins were deployed in Bahrain in 1987 during a period when Iran was laying down mines in the Persian Gulf to disrupt oil shipments. No word yet on whether 'sharks with frickin' laser beams attached' have been added to the U.S. arsenal." Update: 03/14 14:55 GMT by T : Note that (as the Atlantic has updated their story reached via above link) while there really are militarized dolphins in use around the world, this particular story turns out to be an elaborate prank.
