An anonymous reader quotes a report from the BBC: Finnish people often forgo the conversational niceties that are hard-baked into other cultures, and typically don't see the need to meet foreign colleagues, tourists and friends in the middle. As Tiina Latvala, a former English instructor in Sodankyla, Lapland, explained, part of her job was to introduce her young students to the concept of small talk. "We had a practice where you had to pretend to meet someone for the first time," Latvala said. "You had to pretend you were meeting at the cafe or on a bus and [that] you didn't know each other and do a bit of chit chat. We had written on the whiteboard all the safe topics so they didn't have to struggle with coming up with something to talk about. We brainstormed. They usually found it really difficult."

"[They're] about basic conversation," she explained. "The answers are already there. We are taught to answer 'I'm great, how about you?'; 'How is your mum?'. It was very clear how to be in a conversation, as if we didn't already know. It was very weird as if there were right answers to the questions." There are more hypotheses than answers for why Finnish culture has a veil of silence permanently stitched in place. Latvala believes their trademark directness has something to do with the complexity of the Finnish language and the fairly large distance between cities (Latvala's reasoning: If you've travelled any distance to see someone, why waste time?). [...] It isn't for lack of skill, for Finland has two national languages -- Finnish and Swedish -- and Finns begin English lessons when they're six or seven. But rather it's because when faced with expressing themselves in second (or third) language, many often choose to not say anything rather than risk not being fully understood. However, when among their own, silence functions as an extension of comfortable conversation. "'It's not about the structure or features of the language, but rather the ways in which people use the language to do things,' Dr Anna Vatanen, a researcher at the University of Oulu, explained via email. 'For instance, the 'how are you?' question that is most often placed in the very beginning of an encounter. In English-speaking countries, it is mostly used just as a greeting and no serious answer is expected to it. On the contrary, the Finnish counterpart (Mita kuuluu?) can expect a 'real' answer after it: quite often the person responding to the question starts to tell how his or her life really is at the moment, what's new, how they have been doing.'"

As automotive companies shift their focus to software and services in the pursuit of self-driving cars, the impact to large manufacturing cities like Detroit could be drastic. The Wall Street Journal explores this "transformation without precedent" and poses the question: will tech leave Detroit in the dust? From the report: Auto makers point out that they have one advantage that newcomers to the industry don't: vehicles. "Ultimately, you can have the best services platform there is, but if you don't have the vehicles to operate on it, that won't do you much good," said Sam Abuelsamid, a senior analyst with Navigant research. "That's where the manufacturers have an ace in the hole." Many analysts believe businesses like Uber and Alphabet's self-driving tech subsidiary Waymo won't have the appetite to get into the low-margin, capital-intensive business of car manufacturing. Some auto executives say they can hold on to their roles as hardware providers while also tapping into the growth of more-profitable services. Mr. Stackmann said VW can earn millions more customers than it currently has by offering transportation as a service through a network of connected cars. "They talk about scalability, but where is the added value from Uber?" he said. "We have a technical foundation and will build connectivity into our vehicles to connect them and our customers to our ecosystem. In the long term, the question will be: Why do you need Uber?"

Auto industry executives have long seen tech-industry threats coming. The valuation of Elon Musk's Tesla has soared in recent years, pulling even with GM's, as it has shown it can create a fiercely loyal customer base for electric cars. Google began working on autonomous-vehicle technology in 2009 and its self-driving car unit Waymo is today considered a leader in the technology. While demand for new cars and trucks remains robust and selling them will remain a core part of the industry's business in the years to come, many executives believe the long-term profit growth is limited as new forms of transportation proliferate and more car owners ditch their vehicles for shared ones, hurting sales. Car companies are trying to diversify into new business models that, much like Uber, sell transportation as a service. Revenue is generated by usage as opposed to a one-time vehicle sale, and because the service isn't as capital-intensive as building and selling cars, executives believe it can ultimately command higher margins..." The report goes on to mention the investments automobile companies are making to restructure their businesses. GM, Ford, and Toyota, for example, "are investing in new tech startups, purchasing artificial-intelligence and robotics firms, and hiring thousands of workers in tech hubs in California and Tel Aviv, Israel," reports the WSJ. "Several car companies have acquired or invested in makers of lidar, laser-based sensors that help driverless cars navigate. The auto makers are tapping the tech world for software-engineering talent, a skill traditionally in short supply in the car business."

"Over the last year, GM has taken journalists and investors through a factory in suburban Detroit, where workers plan to build self-driving Chevrolet Bolt electric cars that have no steering wheels or brake pedals," reports the WSJ. "The message: It has the manufacturing might to crank out thousands of robot cars, while tech rivals like Alphabet's Waymo unit must equip their autonomous systems onto vehicles they purchase from traditional car companies."

Germany is backing a global minimum tax rate as Europe looks to levy tax notably on U.S. tech giants. "Europe is trying to devise a strategy to tax profits from the likes of Google, Amazon, Facebook, Apple and digital platforms such as YouTube and Airbnb which currently manage to keep fiscal exposure to a bare minimum," reports Yahoo News. From the report: "We need a minimum tax rate valid globally which no state can get out of (applying)," Scholz, a social democrat in conservative Chancellor Angela Merkel's coalition government, told the "Welt am Sonntag" weekly. Digital platforms "aggravate a problem which we know well from globalization and which we are trying to counter -- the shifting of profits to fiscally beneficial regions," said Scholz. Scholz explained he had launched an initiative designed to help states react to so-called fiscal dumping in support of embryonic OECD plans designed to fight tax transparency and cross-border tax evasion. "We require coordinated mechanisms which prevent the displacement of revenues to tax havens," said Scholz. A March proposal by the Commission includes introducing a tax as a bridge measure until such time as the OECD can roll out a measure which can be applied globally.

An anonymous reader shares new work that could allow us to generate electricity using supercritical carbon dioxide. Ars Technica reports: The researchers involved in the new work, a large U.S.-based collaboration, focus on a composite material: tungsten and zirconium carbide. These have extremely high melting points: 3,700K for both materials. Both of them conduct heat extremely well, and neither of them expands or softens much under these conditions, meaning they would hold up better to the mechanical stresses. While the stats are impressive, the amazing part of this is how the material is fabricated. The researchers started with tungsten carbide, a ceramic that can be formed into a porous material simply by pouring it as a powder into a mold and heating it. At this point, the ceramic can be further machined to produce a final shape. Once in its final form, the ceramic was placed in a bath of a molten mixture of copper and zirconium. The molten mixture filled the pores, and the zirconium reacted with the tungsten carbide, replacing the tungsten. The copper in the molten material formed a thin film on the surface of the solid.

The tungsten then filled the pores in the resulting material, allowing it to retain the same shape and size despite the chemical changes. The zircon carbide ends up providing the material with a stiffness even at high temperatures, while the tungsten is flexible enough to keep the whole thing from being brittle. And the whole thing conducted heat better than the metals currently in use. The remaining issue is that, at the conditions involved in solar thermal plants, the copper on the material would react with the carbon dioxide, forming a copper oxide and releasing carbon monoxide. But the researchers determined that adding a small amount of carbon monoxide to the supercritical CO2 would suppress this reaction, something that they confirmed experimentally. Because the material holds up to these conditions so much better than the metals currently in use, it's possible to use much less of it to build a heat exchanger. This is great economically (since you need fewer raw materials), and the small size increases the power density and efficiency of the heat exchanger.

An anonymous reader quotes Gizmodo: When it was discovered earlier this month that the 1809 build of Windows 10 was deleting user files just because, Microsoft halted the update until the problem was fixed. Shame, then, that another not-as-bad-but-still-bad file overwriting bug has now reared its head. in 1809, overwriting files by extracting from an archive using File Explorer doesn't result in an overwrite prompt dialogue and also doesn't replace any files at all; it just fails silently. There are also some reports that it did overwrite items, but did so silently without asking.
Ars Technica speculates that there's a larger program with Microsoft's testing process: [M]any of the preview builds had a bug wherein deleting a directory that was synced to OneDrive crashed the machine. Not only was this bug integrated into the Windows code, it was allowed to ship to end users. This tells us some fundamental things about how Windows is being developed. Either tests do not exist at all for this code (and I've been told that yes, it's permitted to integrate code without tests, though I would hope this isn't the norm), or test failures are being regarded as acceptable, non-blocking issues, and developers are being allowed to integrate code that they know doesn't work properly...

Microsoft's new development process has, proportionately, a greater amount of time spent writing new features, and a reduced amount of time stabilizing and fixing those features. That would be fine if the quality of the features were higher to start with, with the testing infrastructure to support it and higher standards before new code was integrated. But the experience with Windows 10 thus far is that Microsoft hasn't developed the processes and systems needed to sustain this new approach.

TechCrunch reports: A major new campaign of disinformation around Brexit, designed to stir up U.K. 'Leave' voters, and distributed via Facebook, may have reached over 10 million people in the U.K., according to new research. The source of the campaign is so far unknown, and will be embarrassing to Facebook, which only this week claimed it was clamping down on "dark" political advertising on its platform. Researchers for the U.K.-based digital agency 89up allege that Mainstream Network -- which looks and reads like a "mainstream" news site but which has no contact details or reporter bylines -- is serving hyper-targeted Facebook advertisements aimed at exhorting people in Leave-voting U.K. constituencies to tell their MP to "chuck Chequers." Chequers is the name given to the U.K. Prime Ministers's proposed deal with the EU regarding the U.K.'s departure from the EU next year.
ABC News reports: When the Justice Department unsealed criminal charges detailing a yearslong effort by a Russian troll farm to "sow division and discord in the U.S. political system," it was the first federal case alleging continued foreign interference in U.S. elections. Earlier Friday, American intelligence officials released a rare public statement asserting that Russia, China, Iran and other countries are engaged in ongoing efforts to influence U.S. policy and voters in future elections. The statement didn't provide details on those efforts. That stood in contrast with the criminal charges, which provided a detailed narrative of Russian activities...

The criminal complaint provided a clear picture that there is still a hidden but powerful Russian social media effort aimed at spreading distrust for American political candidates and causing divisions on social issues such as immigration and gun control.... Court papers describe how the operatives in Friday's case would analyze U.S. news articles and decide how they would draft social media messages about those stories. They also show that Russian trolls have stepped up their efforts with a better understanding the U.S. political climate and messages that are no longer riddled with misspellings.
CNN notes that one week before America's 2016 presidential election, "one of the Kremlin-backed accounts denied that Russian meddling, saying: 'Russia's Putin says Moscow not trying to influence U.S. election.'"

An anonymous reader quotes Space.com: If you're a meteor enthusiast, the year 2018 has been very kind to you. This past summer, the annual Perseid meteor shower reached its peak the day after a new moon, ensuring that no moonlight would hinder those spotting celestial streakers. And looking ahead to December, the Geminid meteor shower, the most prolific of all of the annual displays, will reach its peak when an almost-first-quarter moon is setting during the late evening hours. This will make for excellent viewing conditions. And coming almost midway between these two popular showers, this weekend brings one of the most reliable meteor events. A sort of lesser version of the summertime Perseids, the Orionid meteor shower should reach its peak activity early on Sunday morning...

[Y]ou should wait until around 2 a.m. in your local time zone, when Orion will have climbed well above the horizon. And just prior to the break of dawn, at around 5 a.m., Orion will appear highest in the sky toward the south. That's when Orionid viewing will be at its best... Past studies have demonstrated that about half of all observed Orionids leave trails that last longer than those of other meteors of equivalent brightness. This is undoubtedly connected to the makeup of Halley's Comet; the object produces meteors that start burning up very high in our atmosphere, at around 80 miles (130 km) up, possibly because they are composed of lightweight material. This suggests they came from the diffuse surface of Halley's nucleus as opposed to its core.

Layzej writes: Back in 2005, solar physicists Galina Mashnich and Vladimir Bashkirtsev made a $10,000 bet that global temperatures, driven primarily by changes in the Sun's activity, would fall over the next decade. The bet would compare the then record hot years between 1998 to 2003 with that between between 2012 and 2017. With temperatures falling from their peak during the 1998 super El-Nino, and solar output continuing to fall, this seemed like a sure bet. The results are now in and all datasets show that climate modeler James Annan is the clear winner.

At the time of the wager, Annan had supposed that the reputation of the scientists involved would be enough to ensure payment once the bet was settled. Unfortunately, as was the case with Alfred Russel Wallace's famous 1870 bet against flat-Earthers, the losing parties have refused to pay up.
"More precisely, Bashkirtsev is refusing to pay," writes the climate modeler on his blog, "and Mashnich is refusing to even reply to email.

"With impressive chutzpah, Bashkirtsev proposed we should arrange a follow-up bet which he would promise to honour."

An anonymous reader quotes Forbes: Rockstar Games co-founder and VP Dan Hauser unleashed a storm of controversy when he casually stated in an interview with Vulture that "We were working 100-hour weeks" putting the finishing touches on Red Dead Redemption 2. Reaction was swift with many condemning the ubiquitous practice of crunch time in the video game industry in general and Rockstar's history of imposing harsh demands on its employees in particular... Hauser responded that he was talking about a senior writing team of four people working over a three-week period. This kind of intense short-term engagement was common for the team which had been working together for 12 years. Hauser went on to say that Rockstar doesn't "ask or expect anyone to work anything like this". Employees are given the option of working excessive overtime but doing so is a "choice" not a requirement.

A QA tester at Rockstar's Lincoln studio in the UK has taken to Reddit to answer questions and clarify misconceptions about overtime at Rockstar that have arisen in the wake of Hauser's comments.... He has no knowledge of working conditions at other Rockstar studios. The first thing the poster points out is that he and other QA testers (with the possible exception of salaried staff) are paid for their overtime work. He then writes "The other big thing is that this overtime is NOT optional, it is expected of us. If we are not able to work overtime on a certain day without a good reason, you have to make it up on another day. This usually means that if you want a full weekend off that you will have to work a double weekend to make up for it... We have been in crunch since October 9th 2017 which is before I started working here...."

[A] requirement to opt into weekly overtime shifts and more than a year of required crunch time ranging from 56 to 81.5 hours spent at work each week is a far, far cry from Hauser's claim that overtime is a "choice" offered to Rockstar's employees. The good news is that Rockstar has changed its overtime policies in response to the negative press engendered by Hauser's 100-hours comment [according to the verified Rock Star employed on Reddit]. Beginning next week "all overtime going forward will be entirely optional, so if we want to work the extra hours and earn the extra money (As well as make yourself look better for progression) then we can do, but there is no longer a rule making us do it."
The videogame correspondent for Forbes argues that this "crunch time is the norm" idea in the videogame industry "is unconscionable and untenable. No one, in any line of work, should be expected to sacrifice their family for their job. If people want to devote their life to their job, they should be able to do so but those who would rather work a standard work-week should also be able to do so without suffering adverse job-related consequences." But what do Slashdot's readers think?

Should 'crunch' overtime be optional?

The November issue of Popular Mechanics includes a message from its editors that Elon Musk is "under attack," arguing that while some criticisms have merit, "much of it is myopic and small-brained, from sideline observers gleefully salivating at the opportunity to take him down a peg." But what have these stock analysts and pontificators done for humanity? Elon Musk is an engineer at heart, a tinkerer, a problem-solver -- the kind of person Popular Mechanics has always championed -- and the problems he's trying to solve are hard. Really hard. He could find better ways to spend his money, that's for sure. And yet there he is, trying to build gasless cars and build reusable rockets and build tunnels that make traffic go away. For all his faults and unpredictability, we need him out there doing that. We need people who have ideas. We need people who take risks.

We need people who try.
The magazine includes statements from 12 high-profile supporters, including investor Mark Cuban, who writes "When you invest in a company run by an entrepreneur like Elon, you are investing in the mindset and approach that an entrepreneur brings to the table as much as you are valuing the net present value of future cash flows. That is not typical for public companies that are overwhelmingly run by hired CEOs. My advice for Elon is simple: Be yourself. Be true to your mission. Respect your investors. Ignore your critics."

Meanwhile, in a Friday post on Twitter, Musk jokingly claimed that he'd purchased and then deleted the game of Fortnite, posting a doctored Marketwatch article quoting him as saying "I had to save these kids from eternal virginity."

"Had to been done," tweeted Musk, adding "ur welcome".

America's Multi-State Information Sharing & Analysis Center is operated in collaboration with its Department of Homeland Security's Office of Cybersecurity and Communications -- and they've got some bad news. MS-ISAC released an advisory warning government agencies, businesses, and home users of multiple high-risk security issues in PHP that can allow attackers to execute arbitrary code. Furthermore, if the PHP vulnerabilities are not successfully exploited, attackers could still induce a denial-of-service condition rendering the probed servers unusable... The PHP Group has issued fixes in the PHP 7.1.23 and 7.2.11 releases for all the high-risk bugs that could lead to DoS and arbitrary code execution in all vulnerable PHP 7.1 and 7.2 versions before these latest updates.
But meanwhile, Threatpost reported this week that 62% of the world's web sites are still running PHP version 5 -- even though its end of life is December 31st. "The deadlines will not be extended, and it is critical that PHP-based websites are upgraded to ensure that security support is provided," warned a recent CERT notice.

So far Drupal is the only CMS posting an official notice requiring upgrades to PHP 7 (by March, three months after the PHP 5.6's end of life deadline). Threatpost notes that "There has been no such notice from WordPress or Joomla."

AmiMoJo quotes the Guardian: Plans to build a British jet-powered car to speed at more than 1,000mph through the desert have hit quicksand, after the company behind the Bloodhound project entered administration. The dream of an ultra-fast car to break the land speed record led to the creation of Bloodhound Programme Ltd in 2007, with the idea of also engaging schools and students in engineering. Bloodhound has already built and tested a viable racing car to speeds of 200mph, but the project is in debt and needs to find £25m or face being wound up... Bloodhound said its programme had been a catalyst for research and development, as well as helping interest schoolchildren worldwide in science and engineering, with an associated educational campaign reaching more than 2 million children...

The planned car is a combination of jet, F1 car and spaceship that would cover the length of four and a half football pitches in a second.

An anonymous reader quotes Martin Monperrus, a professor of software at Stockholm's KTH Royal Institute of Technology: Repairnator is a bot. It constantly monitors software bugs discovered during continuous integration of open-source software and tries to fix them automatically. If it succeeds to synthesize a valid patch, Repairnator proposes the patch to the human developers, disguised under a fake human identity. To date, Repairnator has been able to produce 5 patches that were accepted by the human developers and permanently merged in the code base...

It analyzes bugs and produces patches, in the same way as human developers involved in software maintenance activities. This idea of a program repair bot is disruptive, because today humans are responsible for fixing bugs. In others words, we are talking about a bot meant to (partially) replace human developers for tedious tasks.... [F]or a patch to be human-competitive 1) the bot has to synthesize the patch faster than the human developer 2) the patch has to be judged good-enough by the human developer and permanently merged in the code base.... We believe that Repairnator prefigures a certain future of software development, where bots and humans will smoothly collaborate and even cooperate on software artifacts.
Their fake identity was a software engineer named Luc Esape, with a profile picture that "looks like a junior developer, eager to make open-source contributions... humans tend to have a priori biases against machines, and are more tolerant to errors if the contribution comes from a human peer. In the context of program repair, this means that developers may put the bar higher on the quality of the patch, if they know that the patch comes from a bot."

The researchers proudly published the approving comments on their merged patches -- although a conundrum arose when repairnator submitted a patch for Eclipse Ditto, only to be told that "We can only accept pull-requests which come from users who signed the Eclipse Foundation Contributor License Agreement."

"We were puzzled because a bot cannot physically or morally sign a license agreement and is probably not entitled to do so. Who owns the intellectual property and responsibility of a bot contribution: the robot operator, the bot implementer or the repair algorithm designer?"

NASA recently developed a program for manned missions to explore Venus -- even though the planet's surface is 860 degrees, which NASA explains is "hot enough to melt lead." Long-time Slashdot reader Zorro shares this week's article from Newsweek: As surprising as it may seem, the upper atmosphere of Venus is the most Earth-like location in the solar system. Between altitudes of 30 miles and 40 miles, the pressure and temperature can be compared to regions of the Earth's lower atmosphere. The atmospheric pressure in the Venusian atmosphere at 34 miles is about half that of the pressure at sea level on Earth. In fact you would be fine without a pressure suit, as this is roughly equivalent to the air pressure you would encounter at the summit of Mount Kilimanjaro.

Nor would you need to insulate yourself as the temperature here ranges between 68 degrees Fahrenheit and 86 degrees Fahrenheit. The atmosphere above this altitude is also dense enough to protect astronauts from ionising radiation from space. The closer proximity of the sun provides an even greater abundance of available solar radiation than on Earth, which can be used to generate power (approximately 1.4 times greater).... [C]onceivably you could go for a walk on a platform outside the airship, carrying only your air supply and wearing a chemical hazard suit.
Venus is 8 million miles closer to Earth than Mars (though it's 100 times further away than the moon). But the atmosphere around Venus contains traces of sulphuric acid (responsible for its dense clouds), so the vessel would need to be corrosion-resistant material like teflon. (One NASA paper explored the possibility of airbone microbes living in Venus's atmosphere.) There's a slick video from NASA's Langley Research Center titled "A way to explore Venus" showcasing HAVOC -- "High Altitude Venus Operational Concept."

"A recent internal NASA study...led to the development of an evolutionary program for the exploration of Venus," explains the project's page at NASA.gov, "with focus on the mission architecture and vehicle concept for a 30 day crewed mission into Venus's atmosphere." NASA describes the project as "no longer active," though adding that manned missions to the atmosphere of Venus are possible "with advances in technology and further refinement of the concept."

Long-time Slashdot reader Freshly Exhumed writes: Researchers at the University of Dayton Research Institute [Impact Physics Lab] have shown in a video what can happen when a high-mass, consumer-level drone strikes the wing of an aircraft. They provide visual evidence of the damage a 2.1-pound DJI Phantom 2 videography quadcopter would have upon the wing of a Mooney M20, a small, private aircraft. It is not difficult to extrapolate the effects upon an airliner in a similar situation. "We wanted to help the aviation community and the drone industry understand the dangers that even recreational drones can pose to manned aircraft before a significant event occurs," said Kevin Poormon of UDRI.
The video -- titled "Risk in the Sky?" -- simulates a collision at 238 mph in which the drone tears open the wing's leading edge.

"While the quadcopter broke apart, its energy and mass hung together to create significant damage to the wing," said Kevin Poormon, group leader for impact physics at UDRI.
