Why I'm Usually Unnerved When Modern SSDs Die on Us

Slashdot - Tue, 2018-12-11 16:16
Chris Siebenmann, a Unix Systems Administrator at University of Toronto, writes about the inability to figure out the bottleneck when an SSD dies: What unnerves me about these sorts of abrupt SSD failures is how inscrutable they are and how I can't construct a story in my head of what went wrong. With spinning HDs, drives might die abruptly but you could at least construct narratives about what could have happened to do that; perhaps the spindle motor drive seized or the drive had some other gross mechanical failure that brought everything to a crashing halt (perhaps literally). SSDs are both solid state and opaque, so I'm left with no story for what went wrong, especially when a drive is young and isn't supposed to have come anywhere near wearing out its flash cells (as this SSD was). (When a HD died early, you could also imagine undetected manufacturing flaws that finally gave way. With SSDs, at least in theory that shouldn't happen, so early death feels especially alarming. Probably there are potential undetected manufacturing flaws in the flash cells and so on, though.) When I have no story, my thoughts turn to unnerving possibilities, like that the drive was lying to us about how healthy it was in SMART data and that it was actually running through spare flash capacity and then just ran out, or that it had a firmware flaw that we triggered that bricked it in some way.

Doom Turns 25: The FPS That Wowed Players, Gummed Up Servers, and Enraged Admins

Slashdot - Tue, 2018-12-11 15:25
On December 10, 1993, after a marathon 30-hour coding session, the developers at id Software uploaded the first finished copy of Doom for download, the game that was to redefine first-person shooter (FPS) genre. Hours later IT admins wanted id's guts for garters. The Register: Doom wasn't the first FPS game, but it was the iPhone of the field -- it took parts from various other products and packaged them together in a fearsomely addictive package. Admins loathed it because it hogged bandwidth for downloading and was designed to allow network deathmatches, so millions of users immediately took up valuable network resources for what seemed a frivolous pursuit to some curmudgeonly BOFHs. The game was an instant hit -- so much so that within hours of its release admins were banning it from servers to try and cope with the effects of thousands, and then millions of people playing online. It spawned remakes and follow-up games, its own movie (don't bother) and even a glowing endorsement from Bill Gates.

What it's Like To Work in the Biggest Building in the World

Slashdot - Tue, 2018-12-11 14:46
To build a fleet of giant airliners requires a building just as big. Boeing's Everett Factory, built to construct the famous 747, is the biggest enclosed structure in the world. BBC Future: When you're building some of the world's biggest airliners, you need an equally outsized building. When Boeing decided to build the 747 -- a plane so big it would become known around the world as the jumbo jet -- they had to build a factory large enough to build several of them at the same time. If you've ever seen a 747 from close quarters you'll know just how giant Boeing's jumbo is. So it's no surprise the factory which ended up building has to be very big indeed. How big? Try the biggest enclosed building in the world. Boeing started work on the Everett factory in 1967, just as the Boeing 747 project was starting to gather pace. Bill Allen, Boeing's charismatic chief, had realised the company would need a huge amount of space if they were going to build an airliner big enough to carry 400 passengers. They chose an area of woodland some 22 miles (35km) north of Seattle, near an airport that had served as a fighter base during World War Two. [...] Today, the Everett factory easily dwarfs any other building in the world by volume, with the Guinness Book of Records reporting that it occupies 72 million cubic feet (13.3 million cubic metres). [...] Each shift has as many as 10,000 workers, and there are three shifts each day. Over the course of 24 hours, the factory has a population only a little less than the Australian city of Alice Springs. Reese has worked for Boeing for 38 years -- 11 of them running the factory tours -- but says he can still remember his first impression of the factory. "It was very awe-inspiring the first time -- and I would have to say every day since, too. It changes constantly. Each day there's something new." The Everett factory is so big that there's a fleet of some 1,300 bicycles on hand to help cut travel time. It has its own fire station and medical services on station, and an array of cafes and restaurants to feed the thousands of workers.

China To Force Changes To 20 Popular Games, Ban 9 Including Fortnite and PUBG

Slashdot - Tue, 2018-12-11 13:00
An anonymous reader quotes a report from the BBC: A panel of censors set up to vet mobile video games in China has signaled it will be hard to please. State media reports that of the first 20 titles it assessed, nine were refused permission to go on sale. The Xinhua news agency added that developers of the other 11 had been told they had to make adjustments to remove "controversial content." The authorities have voiced concerns about the violent nature of some titles as well as worries about the activity being addictive. It was announced in August that a new body -- the State Administration of Press and Publications -- had taken over responsibility for approving games and that it would limit the number of online titles available. And although it has not been specified, some experts are assuming that the new panel will operate under its auspices. Xinhua said it is comprised of gaming experts, government-employed researchers, and representatives from the media and video games industry. But it provided no other information about who they were or the titles they had already examined. UPDATE: The list of games being examined by the ethics panel has been revealed by users on NGA, a Chinese gaming forum. A number of games, such as League of Legends, Overwatch, Diablo, and World of Warcraft, will need "corrective action," while others will be "banned/withdrawn" entirely. Some of the most popular prohibited titles include Fortnite and PlayerUnknown's Battlegrounds (PUBG).

Californians Have Now Purchased Half a Million EVs

Slashdot - Tue, 2018-12-11 10:00
According Veloz -- an electric car industry group -- electric vehicle sales in California hit a cumulative 512,717 since 2010. "Months of strong U.S. sales in 2018, preceded by a strong 2017, are starting to show a trend: electric vehicles are selling well, especially in places where there are strong monetary and non-monetary incentives to buy them," reports Ars Technica. From the report: "Overall, this year has seen exponential growth in electric car sales," Veloz wrote. "Electric cars accounted for 7.1 percent of California car sales in the first three quarters of the year, with fully electric, zero-emission car sales outpacing plug-in hybrid sales 4.1 percent to 3 percent respectively." Veloz's data tallies not just fully battery-electric vehicles but also plug-in hybrids as well as the much rarer fuel cell vehicles. The group gets its data (PDF) from the blogs InsideEVs and HybridCars.com as well as a market-research firm called Baum & Associates and estimates from the California Air Resources Board (CARB). According to data from InsideEVs, the Tesla Model 3 was the top-selling electric vehicle model in the U.S. in November. In November alone, 18,650 of those vehicles were sold in the U.S. To its credit, Veloz's press release isn't too self-congratulatory. The group writes, "Veloz recognizes that, while electric car sales are increasing at a rapid clip, it is not happening fast enough to achieve the deep cuts in emissions that the state needs to achieve to protect people's health and curb negative impacts on the environment."

Facebook Filed a Patent To Calculate Your Future Location

Slashdot - Tue, 2018-12-11 07:33
Facebook has filed several patent applications with the U.S. Patent and Trademark Office for technology that uses your location data to predict where you're going and when you're going to be offline. BuzzFeed News reports: A May 30, 2017, Facebook application titled "Offline Trajectories" describes a method to predict where you'll go next based on your location data. The technology described in the patent would calculate a "transition probability based at least in part on previously logged location data associated with a plurality of users who were at the current location." In other words, the technology could also use the data of other people you know, as well as that of strangers, to make predictions. If the company could predict when you are about to be in an offline area, Facebook content "may be prefetched so that the user may have access to content during the period where there is a lack of connectivity." Another Facebook patent application titled "Location Prediction Using Wireless Signals on Online Social Networks" describes how tracking the strength of Wi-Fi, Bluetooth, cellular, and near-field communication (NFC) signals could be used to estimate your current location, in order to anticipate where you will go next. This "background signal" information is used as an alternative to GPS because, as the patent describes, it may provide "the advantage of more accurately or precisely determining a geographic location of a user." The technology could learn the category of your current location (e.g., bar or gym), the time of your visit to the location, the hours that entity is open, and the popular hours of the entity. Yet another Facebook patent application, "Predicting Locations and Movements of Users Based on Historical Locations for Users of an Online System," further details how location data from multiple people would be used to glean location and movement trends and to model location chains. According to the patent application, these could be used for a "variety of applications," including "advertising to users based on locations and for providing insights into the movements of users." The technology could even differentiate movement trends among people who live in a city and who are just visiting a city. A Facebook spokesperson said in a statement: "We often seek patents for technology we never implement, and patent applications -- such as this one -- should not be taken as an indication of future plans."
