Facebook Reopens Probe Into Russian Involvement in Brexit (techcrunch.com) 316

An anonymous reader quotes TechCrunch: Facebook has said it will conduct a wider investigation into whether there was Russian meddling on its platform relating to the 2016 Brexit referendum vote in the UK. Wednesday its UK policy director Simon Milner wrote to a parliamentary committee that's been conducting a wide-ranging enquiry into fake news -- and whose chair has been witheringly critical of Facebook and Twitter for failing to co-operate with requests for information and assistance on the topic of Brexit and Russia -- saying it will widen its investigation, per the committee's request. Though he gave no firm deadline for delivering a fresh report -- beyond estimating "a number of weeks".

It's not clear whether Twitter will also bow to pressure to conduct a more thorough investigation of Brexit-related disinformation. At the time of writing the company had not responded to our questions either. At the end of last year committee chair Damian Collins warned both companies they could face sanctions for failing to co-operate with the committee's enquiry -- slamming Twitter's investigations to date as "completely inadequate", and expressing disbelief that both companies had essentially ignored the committee's requests... Independent academic studies have suggested there was in fact significant tweet-based activity generated around Brexit by Russian bots."

Theresa May has said Russia's attempts to "sow discord" in the West could not go unchallenged, and warned Vladimir Putin, "We know what you are up to."

Facebook's response complained that a new investigation "requires detailed analysis of historic data by our security experts, who are also engaged in preventing live threats to our service."

Can A New Open Photo File Format Replace JPEGs? (cnet.com) 271

Got lossless compression? An anonymous reader quotes CNET: Google, Mozilla and others in a group called the Alliance for Open Media are working on a rival photo technology. In testing so far, the images are 15 percent smaller than Apple's HEIC photo format, said Tim Terriberry, a Mozilla principal research engineer working on the project. But smaller sizes are just the beginning... it's got a strong list of allies, an affinity for web publishing and modern features that could make it the best contender yet for overcoming JPEG's 1990s-era shortcomings... JPEG isn't just limited by needlessly large file sizes. It's also weak when it comes to supporting a wider range of bright and dark tones, a broader spectrum of colors, and graphic elements like text and logos...

The HEIC's new rival is from the Alliance for Open Media, a group whose top priority is a video compression technology called AV1 that's free of patent licensing requirements. It's got heavy hitters on board, including top browser makers Google, Microsoft, Mozilla and the most recent new member, Apple -- though Apple's plans haven't been made public. And it's got major streaming-video companies, too: Netflix, Amazon, Hulu, Facebook, videoconferencing powerhouse Intel and Google's YouTube. And with the support of chip designers Intel, Nvidia and Arm, AV1 should get the hardware acceleration that's crucial to making video easy on our laptop and phone batteries.

To use Apple's HEIC, "makers of software, processors and phones must jump through a lot of hoops to license patents," which CNET predicts "means HEIC will have trouble succeeding on the web: patent barriers are antithetical to the web's open nature."

Microsoft Fights Search Warrants for Overseas Emails in the Supreme Court (microsoft.com) 68

Microsoft's Chief Legal Officer writes about "the landmark Microsoft case that will decide whether the U.S. government can use a search warrant to force a company to seize a customer's private emails stored in Ireland and import them to the United States." On Thursday, 289 different groups and individuals from 37 countries signed 23 different legal briefs supporting Microsoft's position that Congress never gave law enforcement the power to ignore treaties and breach Ireland's sovereignty in this way. How could it? The government relies on a law that was enacted in 1986, before anyone conceived of cloud computing... When the U.S. government requires a tech company to execute a warrant for emails stored overseas, the provider must search a foreign datacenter and make a copy abroad, and then import that copy to the United States. This creates a complex issue with huge international consequences. It shouldn't be resolved by taking the law to a place it was never intended to go...

The U.S. Department of Justice's attempt to seize foreign customers' emails from other countries ignores borders, treaties and international law, as well as the laws those countries have in place to protect the privacy of their own citizens... It's also a path that will lead to the doorsteps of American homes by putting the privacy of U.S. citizens' emails at risk. If the U.S. government obtains the power to search and seize foreign citizens' private communications physically stored in other countries, it will invite other governments to do the same thing. If we ignore other countries' laws, how can we demand that they respect our laws?

Amicus briefs supporting Microsoft have been filed in the U.S. Supreme Court by Ireland, France, and the European Commission and European privacy regulators. Microsoft even notes that on this issue, "Fox News agreed with the American Civil Liberties Union."

Donald Knuth Turns 80, Seeks Problem-Solvers For TAOCP (stanford.edu) 71

An anonymous reader writes: When 24-year-old Donald Knuth began writing The Art of Computer Programming, he had no idea that he'd still be working on it 56 years later. This month he also celebrated his 80th birthday in Sweden with the world premier of Knuth's Fantasia Apocalyptica, a multimedia work for pipe organ and video based on the bible's Book of Revelations, which Knuth describes as "50 years in the making."

But Knuth also points to the recent publication of "one of the most important sections of The Art of Computer Programming" in preliminary paperback form: Volume 4, Fascicle 6: Satisfiability. ("Given a Boolean function, can its variables be set to at least one pattern of 0s and 1 that will make the function true?")

Here's an excerpt from its back cover: Revolutionary methods for solving such problems emerged at the beginning of the twenty-first century, and they've led to game-changing applications in industry. These so-called "SAT solvers" can now routinely find solutions to practical problems that involve millions of variables and were thought until very recently to be hopelessly difficult.
"in several noteworthy cases, nobody has yet pointed out any errors..." Knuth writes on his site, adding "I fear that the most probable hypothesis is that nobody has been sufficiently motivated to check these things out carefully as yet." He's uncomfortable printing a hardcover edition that hasn't been fully vetted, and "I would like to enter here a plea for some readers to tell me explicitly, 'Dear Don, I have read exercise N and its answer very carefully, and I believe that it is 100% correct,'" where N is one of the exercises listed on his web site.

Elsewhere he writes that two "pre-fascicles" -- 5a and 5B -- are also available for alpha-testing. "I've put them online primarily so that experts in the field can check the contents before I inflict them on a wider audience. But if you want to help debug them, please go right ahead."

iPhone X Purchase Leads To Police, Battering Ram, and Handcuffs (cbslocal.com) 411

An anonymous reader quotes CBS SFBayArea: On one recent morning, Rick Garcia and his wife Shannon Knuth woke up to a posse of San Francisco police officers at their front door. "I peered through the peephole and I saw a police officer and a battering ram," Garcia said. "We heard 'SFPD' and 'warrant,' and I was like 'what's going on?'" Knuth remembers. It felt like a nightmare yet it was real. Garcia says that within seconds he was dragged into the hallway of his apartment complex, handcuffed, then whisked away to the Taraval Station.... Meanwhile Knuth, who had just got out of the shower, was ordered to sit on the couch... After rifling through the apartment Knuth says the officers finally told her what they were looking for: Her husband's iPhone X.

According to the warrant, it was stolen but Knuth showed them the receipt which proved her husband bought it. Once the officers realized their mistake they called the police station and a squad car brought Garcia home. "They gathered their pry bar and their battering ram and they left," he said. So how could a mistake like that happen? It's still unclear but it turns out Garcia and Knuth bought the iPhone at an Apple store at Stonestown Galleria just a few weeks after 300 iPhone Xs were stolen from a UPS truck in the mall parking lot.

One former police chief says the way it was handled "kind of boggles the mind...

"This was clearly an incident that should have just been a knock and talk, a couple detectives come to the door, knock on the door and they would have gathered the same info that they gathered after they put him in handcuffs and hauled him off to jail."

Apple and Google Are Rerouting Their Employee Buses as Attacks Resume (mashable.com) 292

Slashdot reader sqorbit writes: Apple runs shuttle buses for it's employees in San Francisco. It seems someone who is not happy with Apple has decided to take out their anger on these buses. In an email obtained by Mashable, Apple states "Due to recent incidents of broken windows along the commute route, specifically on highway 280, we're re-routing coaches for the time being. This change in routes could mean an additional 30-45 minutes of commute time in each direction for some riders." It has been reported that at least four buses have had windows broken, some speculating that it might caused by rubber bullets.
"Around four years ago, people started attacking the shuttle buses that took Google employees to and from work, as a way of protesting the tech-company-driven gentrification taking place around San Francisco," remembers Fortune, adding "it seems to be happening again."

At least one Google bus was also attacked, according to the San Francisco Chronicle, which adds that the buses "were not marked with company logos, and the perpetrators are suspected of broadly targeting technology shuttle buses rather than a specific company."
