WheezyJoe writes: In accordance with his wishes, a hard drive formerly belonging to author Terry Pratchett has been crushed by steamroller. According to friend and fellow author Neil Gaiman, Pratchett (who died at 66 in 2015) wanted "whatever he was working on at the time of his death to be taken out along with his computers, to be put in the middle of a road and for a steamroller to steamroll over them all."

According to the article, on August 25, two years after the author's passing, Mr. Pratchett's estate manager and close friend, Rob Wilkins, posted a picture of a hard drive and a steamroller on an official Twitter account they shared. The pictures posted suggest the steamroller was one powered by actual steam.
Minutes later they tweeted a photo of the crushed hard drive -- which will soon be displayed at the Salisbury Museum in England as part of their new exhibit on the life and work of Terry Pratchett.

Less than three weeks after surging past $4,000, Bitcoin reached $5,000 on Asian exchanges Friday. An anonymous reader quotes Fortune: The idea of Bitcoin breaking the symbolic milestone of $5,000 would have been unthinkable to most people at the start 2017, when the price topped $1,000 for the first time. If you're keeping track, the digital currency is up 500% this year, and nearly 2200% since mid-2015, when it was in the doldrums at around $220. There appears to be no single reason for the recent run-up. Instead, it can likely be explained by the same factors driving this year's cryptocurrency bull run: Publicity-driven speculation; New financial products creating unprecedented liquidity; Trading surges in Asian markets; Institutional investors treating digital currency as a permanent new asset class.
"Magical Internet Money Hits $5k" writes Bitcoin News, adding "so far in 2017 bitcoin has outperformed all government issued tender and a vast majority of stocks and commodities."

While the head of the Bitcoin Foundation has urged people to invest "no more than they can afford," Bitcoin now has a market capitalization of $82.6 billion.

An anonymous reader brings an important announcement: Researchers at the University of St Andrews have thrown down the gauntlet to computer programmers to find a solution to a "simple" chess puzzle which could, in fact, take thousands of years to solve, and net a $1 million prize. Computer Scientist Professor Ian Gent and his colleagues, at the University of St Andrews, believe any program capable of solving the famous "Queens Puzzle" efficiently would be so powerful, it would be capable of solving tasks currently considered impossible, such as decrypting the toughest security on the internet. In a paper [PDF] published in the Journal of Artificial Intelligence Research today, the team conclude the rewards to be reaped by such a program would be immense, not least in financial terms with firms rushing to use it to offer technological solutions, and also a $1 million prize offered by the Clay Mathematics Institute in America.

Devised in 1850, the Queens Puzzle originally challenged a player to place eight queens on a standard chessboard so that no two queens could attack each other. This means putting one queen in each row, so that no two queens are in the same column, and no two queens in the same diagonal. Although the problem has been solved by human beings, once the chess board increases to a large size no computer program can solve it.

More than 70 years ago the UK's Royal Air Force dropped an 1,100-pound bomb on Germany. They just found it. An anonymous reader quotes ABC: Residents in two German cities are evacuating their homes as authorities prepare to dispose of World War II-era bombs found during construction work this week. About 21,000 people have been ordered to leave their homes and workplaces in the western city of Koblenz as a precaution before specialists attempt to defuse the 500-kilogram bomb on Saturday afternoon (local time). Among those moved to safety are prison inmates and hospital patients. Officials in the financial capital Frankfurt, meanwhile, are carrying out what is described as Germany's biggest evacuation. Frankfurt city officials have said more than 60,000 residents will have to leave their homes for at least 12 hours.

Failure to defuse the bomb could cause a big enough explosion to flatten a city block, a fire department official said. "This bomb has more than 1.4 tonnes of explosives," Frankfurt fire chief Reinhard Ries said. "It's not just fragments that are the problem, but also the pressure that it creates that would dismantle all the buildings in a 100-metre radius"... Police will ring every doorbell and use helicopters with heat-sensing cameras to make sure nobody is left behind before they start diffusing the bomb.
Reuters notes that every year Germany discovers more than 2,000 tons of live bombs and munitions, adding "In July, a kindergarten was evacuated after teachers discovered an unexploded World War Two bomb on a shelf among some toys."

An anonymous reader quotes Quartz: Ant Financial, the financial services spinoff of e-commerce giant Alibaba, announced Friday it has rolled out a service with a KFC branch in Hangzhou, in eastern China, that lets customer pay for orders with their faces. It works just as one might expect -- diners approach a virtual menu, select the item they want to purchase, and then choose "facial scan" as a payment option. Users must input their phone numbers as an extra layer of verification, but the technology still works even if one's phone is turned off, an Ant Financial spokesperson tells Quartz.

A promotional video shows a young female customer scanning her face while donning a wig and appearing with friends, to tout that the technology can recognize an individual even if they are disguised or in a group... [T]he KFC partnership marks the first time it has been rolled out for commerce. An Ant Financial spokesperson tells Quartz that it intends to roll out the scanning at more locations later.
There's rumors of a similar service coming from Jd.com, according to the article, which also provides several examples of facial recognition technology being used by the Chinese government. "The Communist Party, facing no political opposition or democratic checks, can implement controversial technology with little pushback. This all means that facial recognition in China looks set to steadily move beyond a few novelty cases toward near ubiquity."

Long-time Slashdot reader Andy Smith, a Scotland-based news photographer, writes: I'm a press photographer. Slashdot has previously covered how the police used underhanded tactics to seize some of my work photos. But that was far from the end of the story. Several months of harassment culminated in me being arrested for standing in a field, something protected by law here in Scotland. I was given a police caution, which is a formal alternative to prosecution, but the police then cancelled the caution and prosecuted me anyway. Ironically, I was meant to be joining the police this month as a volunteer, but that has now been delayed by at least six months.
Earlier Andy had filmed the same police sergeant warning him not to photograph a minor traffic accident -- which had "seemed to anger him."

"Computer programming is highly specialized work; it can't be effectively taught in an intensive program," writes Inc. magazine's contributing editor: Last month, two of the country's largest and most well-regarded coding bootcamps closed. While there are still over 90 such camps in the U.S. and Canada, these for-profit intensive software engineering schools aren't successfully preparing their students for programming jobs. According to a recent Bloomberg article, the Silicon Valley recruiter Mark Dinan characterized the bootcamps as "a freaking joke," while representatives of Google and Autodesk said respectively that "most graduates from these programs are not quite prepared" and "coding schools haven't been much of a focus for [us]."

In one sense, the failure of coding bootcamps reflects the near-universal failure of for-profit universities, colleges, and charter schools to provide a usable education. In another sense, though, coding bootcamps represent a profound misunderstanding of what computer programming is all about... Coding at the professional level is highly specialized and requires years of practice to master... the idea of a bootcamp for coding is just as practical as the idea of a bootcamp for surgery.

An anonymous reader quotes a report from The Register: Police departments cannot categorically deny access to data collected through automated license plate readers, California's Supreme Court said on Thursday -- a ruling that may help privacy advocates monitor government data practices. The ACLU Foundation of Southern California and the Electronic Frontier Foundation sought to obtain some of this data in 2012 from the Los Angeles Police Department and Sheriff's Department, but the agencies refused, on the basis that investigatory data is exempt from disclosure laws. So the following year, the two advocacy groups sued, hoping to understand more about how this data hoard is handled. The LAPD, according to court documents, collects data from 1.2 million vehicles per week and retains that data for five years. The LASD captures data from 1.7 to 1.8 million vehicles per week, which it retains for two years. The ACLU contends [PDF] that indiscriminate license plate data harvesting presents a risk to civil liberties and privacy. It argues that constant monitoring has the potential to chill rights of free speech and association and that databases of license plate numbers invite institutional abuse, not to mention security risks.

Thuy Ong reports via The Verge: Now that you've upgraded to a shiny new 4K TV, Sharp has revealed its latest screen to stoke your fear of missing out: a 70-inch Aquos 8K TV. That 8K (7,680 x 4,320) resolution is 16 times that of your old Full HD (1920 x 1080) TV. Sharp calls it "ultimate reality, with ultra-fine details even the naked eye cannot capture," which doesn't seem like a very good selling point. Keep in mind that having a screen with more pixels doesn't buy you much after a certain point, because those pixels are invisible from a distance -- while an 8K panel would be beneficial as a monitor, where you're sitting close, it won't buy you much when leaning back on the couch watching TV. HDR, however, is something else entirely, and fortunately, Sharp's new 8K set is compatible with Dolby Vision HDR and BDA-HDR (for Blu-ray players). The lack of available 8K HDR content is also a problem. But there is some content floating around. The TV will be rolling out to China and Japan later this year, and then Taiwan in February 2018. Sharp is repurposing its 70-inch 8K TV as an 8K monitor (model LV-70X500E) for Europe, which will be on sale in March. There is no news about a U.S. release.

Freshly Exhumed writes: Researchers using the Green Bank Telescope in West Virginia have announced in the Astronomers Telegram that they have detected 15 fast radio bursts -- poorly understood phenomena that are milliseconds-long pulses of radio emission believed to be coming from rapidly spinning neutron stars or black holes in distant galaxies. Of note is their frequency range, seen to be well above typical phenomena. In particular, fast radio burst (FRB) 121102, discovered by a McGill University researcher in 2016, is the only known one to be repeating, an observation that is quite challenging for theorists and dreamers alike.

An anonymous reader quotes a report from The Guardian: The world's most powerful X-ray laser has begun operating at a facility where scientists will attempt to recreate the conditions deep inside the sun and produce film-like sequences of viruses and cells. The machine, called the European X-ray Free Electron Laser (XFEL), acts as a high-speed camera that can capture images of individual atoms in a few millionths of a billionth of a second. Unlike a conventional camera, though, everything imaged by the X-ray laser is obliterated -- its beam is 100 times more intense than if all the sunlight hitting the Earth's surface were focused onto a single thumbnail. The facility near Hamburg, housed in a series of tunnels up to 38 meters underground, will allow scientists to explore the architecture of viruses and cells, create jittery films of chemical reactions as they unfold and replicate conditions deep within stars and planets.

XFEL is the world's third major X-ray laser facility -- projects in Japan and the U.S. have already spawned major advances in structural biology and materials science. The European beam is more powerful, but most significantly has a far higher pulse rate than either of its predecessors. "They can send 100 pulses out per second, we can send 27,000," said Robert Feidenhan'l, chairman of the European XFEL management board. This matters because to study chemical reactions or biological processes, the X-ray strobe is used to capture flickering snapshots of the same system at different time-points that can be stitched together into a film sequence.

Researchers from the Biosciences and Biotechnologies Institute of the French Alternative Energies and Atomic Energy Commission have discovered a new light-driven enzyme, christened fatty acid photodecarboxylase (FAP), that uses blue light to drive the removal of carboxyl groups from fatty acids to form alkanes or alkenes. Such an enzyme could be used as fuel with no further modification. The Biological SCENE reports: FAP joins a select group of so-called photoenzymes, including DNA-repair enzymes called photolyases, that use light for catalysis on their own rather than functioning as part of a larger complex such as photosystems I or II, which are used by plants and algae for photosynthesis. FAP contains flavin adenine dinucleotide (FAD), which commonly serves as a redox cofactor in biological reactions. In the case of FAP, however, FAD absorbs blue light to reach an excited state that abstracts an electron from the carboxylate group of a C12 to C18 fatty acid, which then decarboxylates to yield an alkane or alkene. The study has been published in the journal Science. Further reading: Ars Technica

Alphabet is approaching its final form. After evolving from Google into a corporate parent with distinct arms in far-flung fields like health care and self-driving cars, it is now forming a new holding company called XXVI Holdings Inc. Bloomberg reports: The new structure legally separates Google from other units such as Waymo, its self-driving car business, and Verily, a medical device and health data firm. Google co-founder Larry Page announced Alphabet two years ago to foster new businesses that operate independently from Google. Technically, however, those units, called the "Other Bets," were still subsidiaries of Google. The new structure, unveiled Friday, enables the Other Bets to become subsidiaries of Alphabet on the same legal footing as Google. "We're updating our corporate structure to implement the changes we announced with the creation of Alphabet in 2015," Gina Weakley Johnson, an Alphabet spokeswoman, said. She called the process a legal formality that won't affect ultimate shareholder control, operations, management or personnel at the 75,606 person company. Google is also changing from a corporation to a limited liability company, or LLC. This won't alter the way the business pays taxes, Johnson said. The switch is partly related to Google's transformation from a listed public company into a business owned by a holding company. Now, it's owned by Alphabet, so it effectively has only one investor and no public disclosure obligations. An LLC structure is better suited to this situation. XXVI, the name of the new holding entity, is the number of letters in the alphabet expressed in Roman numerals.

There are many different ways to navigate a smartphone. Some devices employ capacitive touch navigation buttons in favor of on-screen navigation buttons for the back, home and overview commands. Others, such as the recently released Moto Z2 Force and Moto Z2 Play, feature a mini trackpad under the display that lets users navigate their device through a series of swipes (on-screen navigation buttons are used by default, but the option to use the "one button nav" mini trackpad can be enabled in the settings). The upcoming iPhone 8, for example, may feature a software bar in lieu of a physical/virtual home button, introducing new gesture controls for returning to the home screen and switching between apps.

How do you navigate your smartphone? Given the many different options available on the market, do you think there is one method of navigation that trumps the others, or is it a classic case of "different strokes for different folks?"

An anonymous reader quotes a report from Bleeping Computer: Dutch security researcher Victor Gevers has discovered 2,893 Bitcoin miners left exposed on the internet with no passwords on their Telnet port. Gevers told Bleeping Computer in a private conversation that all miners process Bitcoin transactions in the same mining pool and appear to belong to the same organization. "The owner of these devices is most likely a state sponsored/controlled organization part of the Chinese government, " Gevers says, basing his claims on information found on the exposed miners and IP addresses assigned to each device. "At the speed they were taken offline, it means there must be serious money involved," Gevers added. "A few miners is not a big deal, but 2,893 [miners] working in a pool can generate a pretty sum." According to a Twitter user, the entire network of 2,893 miners Gevers discovered could generate an income of just over $1 million per day, if mining Litecoin.
