"Bitcoin and other cryptocurrency miners have created a dearth of mid-range and high-end GPU cards that are selling for twice as much as suggested retail," reports Computerworld. "The reason: miners are setting up server farms with the cards." Lucas123 writes: GPU prices have more than doubled in some cases... Some of the most popular GPUs can't even be found anymore as they've sold out due to demand. Meanwhile, some retailers are pushing back against bitcoin miners by showing favoritism to their traditional gamer customers, allowing them to purchase GPUs at manufacturer's suggested retail price. Earlier this year, NVIDIA asked retailers of its hardware to prioritize sales to gamers over cryptocurrency miners.

The new "biotic revenge hypothesis" suggests that dinosaurs were killed off by toxic plants. (And an inability to recognize the taste of a toxic plant.) the gmr summarizes a new paper reported at Phys.org: The dinosaur population had been drastically decreasing before the asteroid impact, [and] the appearance of the first flowering plants -- angiosperms -- in the fossil record coincides with the gradual disappearance of the dinosaurs... The scientists concluded that though the asteroid played a role in the extinction of dinosaurs, the "plants had already placed severe strain on the species."
Crocodiles (believed to be descended from dinosaurs) also can't recognize the taste of toxic plants -- the researchers tested 10 different species. And they point out that not only did dinosaurs start to disappear before the asteroid impact -- they continued to "gradually disappear for millions of years afterward."

aarondubrow writes: Astronauts and future space tourists face risks from radiation, which can cause illness and injure organs. Researchers from Texas A&M, NASA, and the University of Texas Medical Branch used supercomputers at the Texas Advanced Computing Center to investigate the radiation exposure related to the Manned Orbiting Laboratory mission, planned for the 1960s and 1970s [but never actually flown], during which a dangerous solar storm occurred. They also explored the historical limitations of radiation research and how such limitations could be addressed in future endeavors.
Supercomputers could be "a game-changer" when it comes to predicting the risks of space radiation, allowing NASA to make life-saving decisions in real-time, argues one of the researchers. During that 1972 solar storm, skin and organs would've risked being exposed to radiation in excess of NASA limits, though one of the study's co-authors believes that rather than risking harm to the astronauts, NASA would've promptly terminated that mission.

"Though the study explored the historical missions, the researchers had in mind future commercial space flights, like those proposed by SpaceX or Virgin Galactic, that will likely travel a similar orbit to best show off the beauty of Earth from space."

Long-time Slashdot reader Ichijo writes: A self-driving car was slapped with a ticket after police said it got too close to a pedestrian on a San Francisco street.

The self-driving car owned by San Francisco-based Cruise was pulled over for not yielding to a pedestrian in a crosswalk. Cruise says its data shows the person was far away enough from the vehicle and the car did nothing wrong.... According to data collected by Cruise, the pedestrian was 10.8 feet away from the car when, while the car was in self-driving mode, it began to continue down Harrison at 14th St."

The person in the crosswalk was not injured.

Researchers at Lawrence Berkeley National Lab have successfully printed three-dimensional structures composed entirely of liquids. A special nanoparticle-derived coating can lock water in place for several months in a solution of silicone oil. omaha393 writes: Using a modified 3D printer, the team demonstrated they can reliably print liquid tubes sheathed in surfactants with precision that allows spiral and branching shapes with diameters ranging from micrometers to millimetres. The technique offers a means to finely control small scale synthetic reactions but the team suggest it could lead to wearable, stretchable electronics. A brief video showing the technology is available and the full paper is available at Advanced Materials.

Long-time Slashdot reader Billly Gates writes: Debian is now available in the Windows app store. It joins Ubuntu, Suse Leap, SuSe enterprise, and Kali Linux for those who cannot or do not want to bother with a virtual machine or a full install of the OS. However, it included stable 9.3. 9.4 is available from the repository if you run apt-get update and apt-get upgrade.
"Fedora is not yet available, although Microsoft has stated openly that it is working to make it so," reports Computer Weekly. And there's more: Microsoft has also provided an open source tool called Microsoft WSL/DistroLauncher for users who want to build their own Linux package where a particular distribution is either a) not available yet or b) is available, but the user wants to apply a greater degree of customisation to it than comes as standard.

Slashdot reader silverdirk writes: Compiled languages have long provided access to the OpenGL API, and even most scripting languages have had OpenGL bindings for a decade or more. But, one significant language missing from the list is our old friend/nemesis Bash. But worry no longer! Now you can create your dazzling 3D visuals right from the comfort of your command line!
"You'll need a system with both Bash and OpenGL support to experience it firsthand," explains software engineer Michael Conrad, who created the first version 13 years ago as "the sixth in a series of 'Abuse of Technology' projects," after "having my technical sensibilities offended that someone had written a real-time video game in Perl.

"Back then, my primary language was C++, and I was studying OpenGL for video game purposes. I declared to my friends that the only thing worse would be if it had been 3D and written in Bash. Having said the idea out loud, it kept prodding me, and I eventually decided to give it a try to one-up the 'awfulness'..."

Slashdot reader Qbertino is pursuing a comp sci degree -- and got a surprise during the last exam: being asked to write code on paper. Not that I'd expect an IDE -- it's an exam after all -- but being able to use a screen and a keyboard with a very simple editor should be standard at universities these days... I find this patently absurd in 2018...

What do you think and what are your recent experiences with exams at universities? Is this still standard? What's the point besides annoying students? Did I miss something?
A similar question was asked on Slashdot 16 years ago -- but apparently nothing has changed since 2002.

Leave your best answers in the comments. Should coding exams be given on paper?

An anonymous reader quotes a report from The Verge: Apple is pushing back against the Environmental Protection Agency's proposal to repeal the Clean Power Plan. The company filed a public comment with the EPA today arguing that scrapping the policy, which calls for cutting power plant pollution, would dull the United States' competitive edge in the clean energy economy. The Clean Power Plan (or CPP) was finalized by the Obama administration, and it takes aim at power plants -- the number one carbon polluters in the U.S., according to the Obama-era EPA website. Had the CPP ever taken effect, it would have given power plants until the year 2030 to curb their carbon emissions by about 30 percent, a move that the Obama administration said could protect the environment, public health, and consumer's pocketbooks.

Apple's comment cites the economic advantages of supporting clean energy, including that it provides "corporate electricity buyers with a hedge against fuel price fluctuation." The price of solar and wind don't change like the price of oil, Apple's filing says. (It also notes that China is currently beating the U.S. in clean energy investments.) The company also says that regulating the grid's carbon emissions "power plant by power plant" won't work. It references its own experiences operating with 100 percent renewable energy here in the U.S. and the work of its subsidiary, Apple Energy LLC, which sells the excess electricity the company generates back to the grid. The electricity system is far too interconnected, the filing says, so "regulation should consider the dynamic and interconnected nature of how power is generated, sold and consumed." That's why it supports the clean power plan, which it says provides a nationwide framework for regulating electricity generation: "It is both needed and the smart thing to do."

According to new data from the analytics company Appfigures, the total number of apps in the App Store declined for the first time last year. "Appfigures notes that just 755,000 apps were released for iOS last year, a 29% drop from 2016," reports Fortune. "In contrast, 1.5 million apps were released for Android last year, marking a 17% year-over-year increase." From the report: Over the course of the year, the number of apps in the store declined from 2.2 million to 2.1 million, marking the first time the store had fewer apps at the end of the year than it did in the beginning. The reason for that change is likely Apple's decision to remove older apps from the store that were not being updated regularly, The Verge notes. Last year, Apple removed apps that were not built on 64-bit architecture, something necessary for them to work on newer iPhone models.

New submitter xonen shares a report from NPR: For decades, scientists have thought that black holes should sink to the center of galaxies and accumulate there. But scientists had no proof that these exotic objects had actually gathered together in the center of the Milky Way. Isolated black holes are almost impossible to detect, but black holes that have a companion -- an orbiting star -- interact with that star in ways that allow the pair to be spotted by telltale X-ray emissions. The team searched for those signals in a region stretching about three light-years out from our galaxy's central supermassive black hole. What they found there: a dozen black holes paired up with stars. Finding so many in such a small region is significant, because until now scientists have found evidence of only about five dozen black holes throughout the entire galaxy. What they've found should help theorists make better predictions about how many cosmic smashups might occur and generate detectable gravitational waves. The study has been published in the journal Nature.

An anonymous reader quotes a report from Ars Technica: Hot-air dryers suck in bacteria and hardy bacterial spores loitering in the bathroom -- perhaps launched into the air by whooshing toilet flushes -- and fire them directly at your freshly cleaned hands, according to a study published in the April issue of Applied and Environmental Microbiology. The authors of the study, led by researchers at the University of Connecticut, found that adding HEPA filters to the dryers can reduce germ-spewing four-fold. However, the data hints that places like infectious disease research facilities and healthcare settings may just want to ditch the dryers and turn to trusty towels. Indeed, in the wake of the blustery study -- which took place in research facility bathrooms around UConn -- "paper towel dispensers have recently been added to all 36 bathrooms in basic science research areas in the UConn School of Medicine surveyed in the current study," the authors note. The researchers speculated that "one reason hand dryers may disperse so many bacteria is the large amount of air that passes through hand dryers, 19,000 linear feet/min at the nozzle. The convection generated by high airflow below the hand dryer nozzles could also draw in room air."

"In the first 'right to be forgotten' case to reach England's High Court, two men are fighting to keep their past crimes out of Google's search results, and the tech giant is fighting back by claiming it's 'journalistic.'" Chava Gourarie reports via Columbia Journalism Review: The case, which is actually two nearly identical cases, involves two businessmen who were both convicted of white-collar crimes in the '90s, and requested that Google delist several URLs referencing their convictions, including news articles. When Google denied their requests, they sued under a 2014 European Union ruling which established the right of individuals to have information delisted from search indexes under certain conditions. In its defense, Google has argued that it should be protected under an exception for journalism because it provides access to journalistic content. Even as a legal sleight of hand, the argument is quite a departure from Google's customary efforts to present itself as a disinterested arbiter of information, a position that has become more untenable with time.

Gareth Corfield, a reporter for The Register who covered the cases from the courtroom, said it's disingenuous of Google to put on the mantle of journalism only when it suits them. "They've gone through great lengths to say they don't make any editorial judgement in processing results," Corfield said, but "it now wants you to believe it is on a par with journalism." As the first case to test the "right to be forgotten" in England's High Court, its outcome will likely set some ground rules in the roiling debate between personal privacy and freedom of expression on the internet. Google's sudden identification with journalism may be a legal gambit, but it could have far-reaching effects across the landscape of data protection laws.

According to Twitter's latest transparency report, the social media company removed more than 270,000 accounts around the world for promoting terrorism in the second half of 2017. The number of accounts permanently suspended for sharing what the firm called extremist content between July and December represents a drop for the second period in a row. The Guardian reports: The social network puts this down to "years of hard work making our site an undesirable place for those seeking to promote terrorism." Nick Pickles, Twitter UK's head of public policy, said: "The overwhelming majority of these accounts were detected by our own technology, with just 0.2% of the accounts we suspended in 2017 being flagged by the police." Almost 75% of accounts were suspended before they sent their first tweet, according to the report, and 93% were discovered by tools that Twitter engineers had built. Twitter is understood to also use a combination of US and EU lists of terrorist organizations as well as research from academics and experts to identify terrorists on its network. The number of reports of abusive behavior submitted by government representatives also dropped amid a marked change in the type of abusive behavior reported. Two-thirds of the 10,000 reports concerned violated rules over impersonation, with only 16% of the reports for harassment and 12% for hateful conduct. Harassment and hateful conduct each accounted for a third of reported accounts in the first half of 2017. Only a quarter of reports of abusive behavior submitted by government representatives were acted upon by Twitter, compared with 98% of reports relating to the "promotion of terrorism."
