Star of Film 'Downfall' and Widespread 'Hitler Finds Out...' Meme, Dead At 77 (theguardian.com) 50

The Guardian reports: Bruno Ganz, the Swiss actor who played Adolf Hitler in the film Downfall, has died in Zurich at the age of 77, his agent announced. The actor became internationally renowned for his 2004 portrayal of the German dictator's final days inside his Berlin bunker. In a Guardian review of Downfall Rob Mackie described Ganz as "the most convincing screen Hitler yet: an old, bent, sick dictator with the shaking hands of someone with Parkinson's, alternating between rage and despair in his last days in the bunker...." It is widely believed to be the cinematic footage most often shared online, as well as the cause of one of the world's most productive internet memes.
They're referring to "One climactic scene featuring a Ganz tour de force" that was "relentlessly parodied in widespread 'Hitler Finds Out...' videos, featuring anachronistic subtitles depicting his rage and fury over topical, mundane, or banal events and trivial gossip," explains long-time Slashdot reader Freshly Exhumed:

The spread of the meme was aided inestimably by the Streisand Effect caused when the production company, Constantin Films began sending DMCA takedown notices to YouTube. Eventually the company relented as the parodies constituted strong fair use cases.
When the director of the film was asked about the parodies, he admitted that "I think I've seen about 145 of them! Of course, I have to put the sound down when I watch. Many times the lines are so funny, I laugh out loud, and I'm laughing about the scene that I staged myself! You couldn't get a better compliment as a director."

Ask Slashdot: Could Nikola Tesla's Wardenclyffe Tower Have Worked? 365

dryriver writes: For those who are unfamiliar with the story, from 1901-1902, inventor Nikola Tesla had a 187-foot-tall experimental wireless electricity transmission tower called the "Wardenclyffe Tower" built in Shoreham, New York. Tesla believed that it was possible to generate electrical power on a large scale in one part of the world and transmit that electrical power to electrical receivers in far away parts of the world wirelessly, using parts of Earth's atmosphere as the conducting medium. Tesla had huge problems getting the project financed -- powerful banker J.P. Morgan didn't play along and U.S. President Woodrow Wilson didn't help a pleading Tesla either. An excerpt from a Wardenclyffe documentary shows the tower finally being dynamited and sold for scrap in 1917. The Wardenclyffe Tower never reached operational status; wireless electrical transmission between continents never happened; Tesla became an emotionally broken man who died regretting that he did not manage to finish his life's work; and to this day nobody knows exactly how the Wardenclyffe Tower was supposed to function technically. To the question: Do you believe that Tesla's dream of electrical devices anywhere in the world essentially being able to draw electrical power from the sky with a relatively simple antenna could have worked, had he gotten the necessary funding to complete his experiments?

Countries With Zero Rating Have More Expensive Wireless Broadband Than Countries Without It 160

A comprehensive multi-year study by the non-profit Epicenter.works, comparing the 30 member countries of the European Union (EU) on net neutrality enforcement, has found that zero rating business practices by wireless carriers have increased the cost of wireless data compared to countries without zero rating. From a report: This directly contradicts all of the assertions by major wireless carriers that their zero rating practices are "free data" for consumers. Based on the evidence, zero rating not only serves as a means to enhance ISPs' power over the Internet, but it's also how they charge consumers more money for wireless service. Zero rating was originally going to be banned by the FCC under the General Conduct Rule, but when the FCC changed leadership the agency promptly green lighted and encouraged the industry to engage in zero rating practices before it began its repeal of net neutrality.

'The Fundamental Problem With Silicon Valley's Favorite Growth Strategy' (qz.com) 114

Tim O'Reilly, writing for Quartz: The pursuit of monopoly has led Silicon Valley astray. Look no further than the race between Lyft and Uber to dominate the online ride-hailing market. Both companies are gearing up for their IPOs in the next few months. Street talk has Lyft shooting for a valuation between $15 and $30 billion dollars, and Uber valued at an astonishing $120 billion dollars. Neither company is profitable; their enormous valuations are based on the premise that if a company grows big enough and fast enough, profits will eventually follow.

Most monopolies or duopolies develop over time, and have been considered dangerous to competitive markets; now they are sought after from the start and are the holy grail for investors. If LinkedIn co-founder Reid Hoffman and entrepreneur Chris Yeh's new book Blitzscaling is to be believed, the Uber-style race to the top (or the bottom, depending on your point of view) is the secret of success for today's technology businesses. Blitzscaling promises to teach techniques that are "the lightning fast path to building massively valuable companies." Hoffman and Yeh argue that in today's world, it's essential to "achieve massive scale at incredible speed" in order to seize the ground before competitors do. By their definition, blitzscaling (derived from the blitzkrieg or "lightning war" strategy of Nazi general Heinz Guderian) "prioritizes speed over efficiency," and risks "potentially disastrous defeat in order to maximize speed and surprise."

Many of these businesses depend on network effects, which means that the company that gets to scale first is likely to stay on top. So, for startups, this strategy typically involves raising lots of capital and moving quickly to dominate a new market, even when the company's leaders may not know how they are going to make money in the long term. This premise has become doctrine in Silicon Valley. But is it correct? And is it good for society? I have my doubts. Imagine, for a moment, a world in which Uber and Lyft hadn't been able to raise billions of dollars in a winner-takes-all race to dominate the online ride-hailing market. How might that market have developed differently?

Modern Weather Forecasts Are Stunningly Accurate (theatlantic.com) 153

An anonymous reader quotes a report from The Atlantic: Meteorologists have never gotten a shiny magazine cover or a brooding Aaron Sorkin film, and the weather-research hub of Norman, Oklahoma, is rarely mentioned in the same breath as Palo Alto. But over the past few decades, scientists have gotten significantly -- even staggeringly -- better at predicting the weather. How much better? "A modern five-day forecast is as accurate as a one-day forecast was in 1980," says a new paper, published last week in the journal Science. "Useful forecasts now reach nine to 10 days into the future." "Modern 72-hour predictions of hurricane tracks are more accurate than 24-hour forecasts were 40 years ago," the authors write. The federal government now predicts storm surge, stream level, and the likelihood of drought. It has also gotten better at talking about its forecasts: As I wrote in 2017, the National Weather Service has dropped professional jargon in favor of clear, direct, and everyday language. "Everybody's improving, and they're improving a lot," says Richard Alley, an author of the paper and a geoscientist at Penn State.

Understanding months-long events like El Niño, for instance, has allowed meteorologists to go beyond the seven-day forecast. Alley, the Penn State professor, says that he is awed by the new models. Well-studied features of Earth's climate -- like the temperate Gulf Stream in the Atlantic Ocean -- emerge in computer models, even though developers have written code that only mimics basic physics. We are now surrounded by the products of these miraculous models. In 2009, a back-of-the-envelope study estimated that U.S. adults check the weather forecast about 300 billion times per year. Perhaps in all that checking we have forgotten how strange the forecast is, how almost supernatural it is that people can describe the weather before it happens. More than 1,000 years ago, the Spanish archbishop Agobard of Lyon argued that no witch could control the weather because only God could understand it. "Man does not know the paths of the clouds, nor their perfect knowledges," he wrote. He cited the Book of Job for authority, which asks: "Dost thou know when God caused the light of his cloud to shine? Dost thou know the balancings of the clouds ?"

China Is Restarting Its Reactor Pipeline, Westinghouse Isn't Invited (technologyreview.com) 146

"China hasn't launched a new nuclear reactor build for over two years, but Chinese press reports that this nuclear hiatus has broken," writes Slashdot reader carbonnation. "Approvals have reportedly been made for four Hualong One reactors -- a domestic "Generation III" design -- instead of U.S.-designed AP1000s." From a report via MIT Technology Review: China's Jiemian News started the chatter on Tuesday with an exclusive interview with senior leadership of the Hualong One design's owner, Hualong International Nuclear Power Technology, a collaboration of nuclear heavyweights China General Nuclear Power (CGN) and China National Nuclear Corp. (CNNC). According to the news site, the joint venture's leaders said that two dual-reactor projects had received provisional permission to begin pouring concrete. Other publications also picked up the story yesterday, including First Financial Journal, which claimed to have confirmed the approvals through "relevant authoritative channels." CNNC and CGN have not responded to the media reports.

The reactors are slated for two new sites along China's coast: CNNC's Zhangzhou power project in Fujian and CGN's Huizhou Taipingling project in Guangdong. Both projects had been planned and approved by Chinese authorities with Westinghouse's AP1000 reactor design, which promises safety advances such as passive cooling. That means it stores water above the reactor, leveraging gravity to keep the plant cool should the pumps fail. But Westinghouse's flagship AP1000 projects have been plagued by cost overruns and delays. Those troubles may have helped the Hualong One to catch up. CNNC started building the first Hualong One reactor in 2015 at its Fuqing power plant and expects to have it operating later this year.

Meet the Man Behind a Third of What's On Wikipedia (cbsnews.com) 189

Thelasko shares a report from CBS News: Steven Pruitt has made nearly 3 million edits on Wikipedia and written 35,000 original articles. It's earned him not only accolades but almost legendary status on the internet. The online encyclopedia now boasts more than 5.7 million articles in English and millions more translated into other languages -- all written by online volunteers. Pruitt was named one of the most influential people on the internet by Time magazine in part because one-third of all English language articles on Wikipedia have been edited by Steven. An incredible feat, ignited by a fascination with his own history.

How much money does he make from his work? None. "The idea of making it all free fascinates me. My mother grew up in the Soviet Union ... So I'm very conscious of what, what it can mean to make knowledge free, to make information free," he said. Pulling from books, academic journals and other sources, he spends more than three hours a day researching, editing and writing. Even his day job is research, working in records and information at U.S. Customs and Border Protection. He joked that his colleagues probably think he's nuts. To put in to perspective what it took for Pruitt to become the top editor, he's been dedicating his free time to the site for 13 years. The second-place editor is roughly 900,000 edits behind him, so his first place status seems safe, for now.

Google Commits $3.1 Million and Free Cloud APIs To Wikimedia (venturebeat.com) 44

Google is expanding its support of Wikimedia, the parent company of Wikipedia, as the search giant chases the next billion users. From a report: At World Economic Forum this week, Google committed to offer Wikipedia an additional $3.1 million, along with providing several of its machine learning tools to the editors of Wikipedia at no cost, the companies said. Google.org, thanks in part to contributions from employees, will be giving $1.1 million to the Wikimedia Foundation and $2 million to the Wikimedia Endowment, an independent fund that supports Wikipedia and other long-term Wikimedia projects.

As part of the announcement, the companies said they will be expanding Project Tiger, a joint initiative they launched in 2017 to increase the number of articles in underrepresented languages in India. They intend to provide editors with resources and insights to create new Wikipedia articles across 10 languages in India, Indonesia, Mexico, Nigeria, and the Middle East and North Africa (MENA) region. The initiative is being rebranded as GLOW, which is supposed to stand for Growing Local Language Content on Wikipedia.

Google Fined $57 Million By French Data Privacy Body For Failing To Comply With EU's GDPR Regulations (venturebeat.com) 109

schwit1 shares a report from VentureBeat: Google has been hit by a $57 million fine by French data privacy body CNIL (National Data Protection Commission) for failure to comply with the EU's General Data Protection Regulation (GDPR) regulations. The CNIL said that it was fining Google for "lack of transparency, inadequate information and lack of valid consent regarding the ads personalization," according to a press release issued by the organization. The news was first reported by the AFP. What the CNIL is effectively referencing here is dark pattern design, which attempts to encourage users into accepting terms by guiding their choices through the design and layout of the interface. This is something that Facebook has often done too, as it has sought to garner user consent for new features or T&Cs.

It's worth noting here that Google has faced considerable pressure from the EU on a number of fronts over the way it carries out business. Back in July, it was hit with a record $5 billion fine in an Android antitrust case, though it is currently appealing that. A few months back, Google overhauled its Android business model in Europe, electing to charge Android device makers a licensing fee to preinstall its apps in Europe. Google hasn't confirmed what its next steps will be, but it will likely appeal the decision as it has done with other fines. "People expect high standards of transparency and control from us," a Google spokesperson told VentureBeat. "We're deeply committed to meeting those expectations and the consent requirements of the GDPR. We're studying the decision to determine our next steps."

Venezuela's Government Blocks Access To Wikipedia (haaretz.com) 208

Haaretz (with contributions from Reuters and the Associated Press) reports: According to NetBlocks, a digital rights group that tracks restrictions to the internet, as of 12 January, Venezuela largest telecommunications provider CANTV has prevented access to Wikipedia in all languages. The internet observatory told Haaretz the ban was discovered by attempting "to access Wikipedia and other services 60,000 times from 150 different points in the country using multiple providers."

Roughly 16 million people have access to the internet in the South American country ravaged by poverty and now facing a political crisis as leader Nicolas Maduro attempts to cling to power following a highly contested re-election last year. Wikipedia receives on average 60 million views from the country every month.

According to NetBlocks, the ban was likely imposed after a Wikipedia article listed newly-appointed National Assembly president Juan Guaidà as âoepresident number 51 of the Bolivarian Republic of Venezuela,â ousting Maduro from his presidential status on Wikipedia... Alp Toker, the head of NetBlocks, explained to Haaretz that the block followed a string of controversial edits on the Spanish-language article for Guaido as well as other related articles.

Long-time Slashdot reader williamyf identifies himself as "a Venezuelan in Venezuela." He reports that "The method used seems to be to intercept the SSL handshake and not a simple DNS block," adding "the situation is developing."

In May of last year the government declared a "state of emergency" that authorized the government to police the internet and filter content, rights activists reported Monday. They added that now Venezuela's new leaders plan to introduce legislation requiring messaging service providers to censor content, and implementing other so-called "content security" measures.

Happy 18th Birthday, Wikipedia (washingtonpost.com) 85

This week, Wikipedia celebrates its 18th birthday. If the massive crowdsourced encyclopedia project were human, then in most countries, it would just now be considered a legal adult. But in truth, the free online encyclopedia has long played the role of the Internet's good grown-up. From a story: Wikipedia has grown enormously since its inception: It now boasts 5.7 million articles in English and pulled in 92 billion page views last year. The site has also undergone a major reputation change. If you ask Siri, Alexa or Google Home a general-knowledge question, it will likely pull the response from Wikipedia. The online encyclopedia has been cited in more than 400 judicial opinions, according to a 2010 paper in the Yale Journal of Law & Technology.

Many professors are ditching the traditional writing assignment and instead asking students to expand or create a Wikipedia article on the topic. And YouTube Chief Executive Susan Wojcicki announced a plan last March to pair misleading conspiracy videos with links to corresponding articles from Wikipedia. Facebook has also released a feature using Wikipedia's content to provide users more information about the publication source for articles in their feed.

DerbyCon Will Hold Its Last InfoSec Conference in September This Year (derbycon.com) 176

DerbyCon 9.0, the upcoming edition of the popular InfoSec conference in September, will be its last. From an official announcement: When we first started DerbyCon, our goal was to create a conference where we could all come together to collaborate and share as a community, but most importantly as a profession. DerbyCon 1.0 was a huge gamble for us both personally and financially, but we believed in what we were doing, and it worked. For those that don't know the history of DerbyCon, it started off inside of a pizza shop as an idea between a few friends. Our goal was to create an affordable conference that shared a lot of what we had experienced in our early days in security. The ideas of collaboration, community, and the betterment of the industry and the safety of technology were at the forefront. At the end of DerbyCon 1.0, we realized that the conference was a huge success and our dream became a reality.

[...] What we have had to deal with on the back-end the past few years is more than just running a conference and sharing with friends. The conference scene in general changed drastically and small pocket groups focus on outrage and disruption where there is no right answer (regardless of how you respond, it's wrong), instead of coming together, or making the industry better. There is a small, yet vocal group of people creating negativity, polarization, and disruption, with the primary intent of self-promotion to advance a career, for personal gain, or for more social media followers. Individuals that would have us be judge, jury, and executioner for people they have had issues with outside of the conference that has nothing to do with the conference itself.

Instead of working hard in research, being a positive force in the industry, or sharing their own unique experiences (which makes us better as a whole), they tear others down in order to promote themselves. This isn't just about DerbyCon, it is present at other conferences as well and it's getting worse each year. We've spoken with a number of conference organizers, and each year it becomes substantially more difficult to host a conference where people can come together in large group settings. It's not just conferences either. This behavior is happening all over the place on social media, in our industry, targeting people trying to do good. As a community, we add fuel to fire, attack others, and give them a platform in one massive toxic environment. We do this all in fear of repercussions from upsetting others. Until this pattern changes, it will continue to get worse.

Blue Gems In Teeth Illuminate Women's Hidden Role In Medieval Manuscripts (abc.net.au) 127

brindafella writes: The jaw bone of a woman who died around 1000-1200 AD has specks of precious lapis lazuli (mineral) in the plaque of her teeth. This indicates that this woman would have licked the brush used in preparing precious illuminated manuscripts at the women's monastery in Dalheim in western Germany. The study by researchers from German-based Max Planck Institute for the Science of Human History and Britain's University of York showed that women, as well as men, were part of the production of the valuable manuscripts. "The researchers said this challenged long-held beliefs that women had played little role in the European Middle Ages in producing literary and written texts which came largely from religious institutions," reports the Australian Broadcasting Corporation. "Researcher Christina Warinner said this finding from the 11th century was unprecedented in showing more women were literate, educated and encouraged to read at that time."

Google Search Results Listings Can Be Manipulated For Propaganda (zdnet.com) 44

A feature of the Google search engine lets threat actors alter search results in a way that could be used to push political propaganda, oppressive views, or promote fake news. From a report: The feature is known as the "knowledge panel" and is a box that usually appears at the right side of the search results, usually highlighting the main search result for a very specific query. For example, searching for Barack Obama would bring a box showing information from Barack Obama's Wikipedia page, along with links to the former president's social media profiles. But Wietze Beukema, a member of PwC's Cyber Threat Detection & Response team, has discovered that you can hijack these knowledge panels and add them to any search query, sometimes in a way that pushes legitimate search results way down the page, highlighting an incorrect result and making it look legitimate. The way this can be done is by first searching for a legitimate item, and pressing the "share" icon that appears inside a knowledge panel.

Security Researcher Cracks Google's Widevine DRM (L3 Only) (zdnet.com) 76

The L3 protection level of Google's Widevine DRM technology has been cracked by a British security researcher who can now decrypt content transferred via DRM-protected multimedia streams. ZDNet's Catalin Cimpanu notes that while this "sounds very cool," it's not likely to fuel a massive piracy wave because "the hack works only against Widevine L3 streams, and not L2 and L1, which are the ones that carry high-quality audio and video content." From the report: Google designed its Widevine DRM technology to work on three data protection levels --L1, L2, and L3-- each usable in various scenarios. According to Google's docs, the differences between the three protection levels is as follows:

L1 - all content processing and cryptography operations are handled inside a CPU that supports a Trusted Execution Environment (TEE).
L2 - only cryptography operations are handled inside a TEE.
L3 - content processing and cryptography operations are (intentionally) handled outside of a TEE, or the device doesn't support a TEE

"Soooo, after a few evenings of work, I've 100% broken Widevine L3 DRM," [British security researcher David Buchanan] said on Twitter. "Their Whitebox AES-128 implementation is vulnerable to the well-studied DFA attack, which can be used to recover the original key. Then you can decrypt the MPEG-CENC streams with plain old ffmpeg." Albeit Buchanan did not yet release any proof-of-concept code, it wouldn't help anyone if he did. In order to get the DRM-encrypted data blob that you want to decrypt, an attacker would still need "the right/permission" to receive the data blob in the first place. If a Netflix pirate would have this right (being an account holder), then he'd most likely (ab)use it to pirate a higher-quality version of the content, instead of bothering to decrypt low-res video and lo-fi audio. The only advantage is in regards to automating the pirating process, but as some users have pointed out, this isn't very appealing in today's tech scene where almost all devices are capable of playing HD multimedia [1, 2].

Apple's AirPower, Unveiled in September 2017, Officially Misses 2018 Shipping Deadline (9to5mac.com) 137

From a 9to5Mac report: As the new year begins in Pacific Time, where Apple's Cupertino headquarters are based, the AirPower charging mat has officially missed its 2018 release window. The charging mat promised to charge iPhone, Apple Watch and AirPods on a single compact mat with flexibility on where devices can be placed. However, the product has been rumored to have faced internal development challenges as late as this past summer, which prevented Apple from bringing the product to market as smoothly as it expected.

[...] Unusually, Apple has not provided a statement to press with an update on AirPower's status. Apple refused to acknowledge the product at its September and October events, and has not responded to press requests for comment at the end of December. The product therefore enters 2019 still in limbo.

Nancy Grace Roman, 'Mother Of Hubble' Space Telescope, Has Died, At Age 93 (npr.org) 65

Russell Lewis, writing for NPR: When Nancy Grace Roman was a child, her favorite object to draw was the moon. Her mother used to take her on walks under the nighttime sky and show her constellations, or point out the colorful swirls of the aurora. Roman loved to look up at the stars and imagine. Eventually, her passion for stargazing blossomed into a career as a renowned astronomer. Roman was one of the first female executives at NASA, where she served as the agency's first chief of astronomy. Known as the "Mother of Hubble," for her role in making the Hubble Space Telescope a reality, Roman worked at NASA for nearly two decades. She died on Dec. 25 at the age of 93.

Roman fought to earn her place in a field dominated by men, paving the path for future female scientists. She was born in Nashville, Tenn. in 1925 and organized an astronomy club in fifth grade. She attended high school in Baltimore, where she requested to take a second year of algebra instead of a fifth year of Latin. When she made the appeal, she recounted in a 2017 interview with NPR that the guidance counselor wasn't supportive of her dream to become a scientist.

Her efforts helped lead to the creation of the Hubble Space Telescope. In her role at NASA, Roman developed and planned the Hubble Space Telescope, which is famous for its stunning images of space. Because of the Hubble Space Telescope, scientists have been able to collect data and gain insight into even the most remote galaxies of the universe. The success of the project led to future space telescopes. Roman's work, however, reached far beyond just the Hubble Space Telescope. In an interview with NASA, Roman once stated that one of the highlights of her career was when she discovered the first indication that common stars were not all the same age.

Artificial General Intelligence is Nowhere Close To Being a Reality (venturebeat.com) 303

Three decades ago, David Rumelhart, Geoffrey Hinton, and Ronald Williams wrote about a foundational weight-calculating technique -- backpropagation -- in a monumental paper titled "Learning Representations by Back-propagating Errors." Backpropagation, aided by increasingly cheaper, more robust computer hardware, has enabled monumental leaps in computer vision, natural language processing, machine translation, drug design, and material inspection, where some deep neural networks (DNNs) have produced results superior to human experts. Looking at the advances we have made to date, can DNNs be the harbinger of superintelligent robots? From a report: Demis Hassabis doesn't believe so -- and he would know. He's the cofounder of DeepMind, a London-based machine learning startup founded with the mission of applying insights from neuroscience and computer science toward the creation of artificial general intelligence (AGI) -- in other words, systems that could successfully perform any intellectual task that a human can. "There's still much further to go," he told VentureBeat at the NeurIPS 2018 conference in Montreal in early December. "Games or board games are quite easy in some ways because the transition model between states is very well-specified and easy to learn. Real-world 3D environments and the real world itself is much more tricky to figure out ... but it's important if you want to do planning."

Most AI systems today also don't scale very well. AlphaZero, AlphaGo, and OpenAI Five leverage a type of programming known as reinforcement learning, in which an AI-controlled software agent learns to take actions in an environment -- a board game, for example, or a MOBA -- to maximize a reward. It's helpful to imagine a system of Skinner boxes, said Hinton in an interview with VentureBeat. Skinner boxes -- which derive their name from pioneering Harvard psychologist B. F. Skinner -- make use of operant conditioning to train subject animals to perform actions, such as pressing a lever, in response to stimuli, like a light or sound. When the subject performs a behavior correctly, they receive some form of reward, often in the form of food or water. The problem with reinforcement learning methods in AI research is that the reward signals tend to be "wimpy," Hinton said. In some environments, agents become stuck looking for patterns in random data -- the so-called "noisy TV problem."
