"Elon Musk predicted in March, at the beginning of the coronavirus pandemic, that there would be 'probably close to zero new cases' in the United States by the end of April," reports the Washington Post.

"Now, the Tesla chief executive is trying to figure out whether he has a virus that has killed at least 242,000 Americans." The billionaire said early Friday that he's experiencing cold-like symptoms, but that four rapid tests have produced two positives and two negatives — an experience that left him questioning the process.

"Something extremely bogus is going on," Musk, 49, tweeted. "Was tested for covid four times today. Two tests came back negative, two came back positive. Same machine, same test, same nurse..."
UPDATE: Thursday Musk tweeted he was also in the process of getting "PCR tests" — plural — "from separate labs," with results to be delivered within 24 hours. On Saturday, Musk then tweeted the news that he "most likely" has a moderate case of Covid-19.

Musk had said he had "symptoms of a typical cold," tweeting that for the past few days he's had "slight fever" and "mild sniffles" — and that he'd been taking NyQuil.

"The Nov. 3rd election was the most secure in American history," state and federal election officials said in a statement Thursday. "There is no evidence that any voting system deleted or lost votes, changed votes, or was in any way compromised." Bloomberg reports: The statement acknowledged the "many unfounded claims and opportunities for misinformation about the process of our elections" and urged Americans to turn to election administrators and officials for accurate information. The statement was signed by officials from the Elections Infrastructure Government Coordinating Council, which shares information among state, local and federal officials, and the Election Infrastructure Sector Coordinating Council, which includes election infrastructure owners and operators.

Among the 10 signatories were Benjamin Hovland, who chairs the U.S. Election Assistance Commission, and Bob Kolasky, the assistant director of the Cybersecurity and Infrastructure Security Agency, part of the Department of Homeland Security. Key officials at the cybersecurity agency, including its head, Christopher Krebs, are stepping down or expecting to get fired as Trump refuses to concede. Krebs, who has enjoyed bipartisan support for his role in helping run secure U.S. elections in 2018 and 2020, has told associates he expects to be dismissed, according to three people familiar with internal discussions. His departure would follow the resignation of Bryan Ware, assistant director for cybersecurity at CISA, who resigned on Thursday morning after about two years at the agency. In addition, Valerie Boyd, the assistant secretary for international affairs at the Department of Homeland Security, which oversees CISA, has also left, according to two other people. Krebs and Ware are both Trump appointees.

An anonymous reader quotes a report from The New York Times: Shekinah and Orlandria Lennon were sitting at their kitchen table this fall, taking online classes, when video of their teachers and fellow students suddenly froze on their laptop screens. The wireless antenna on the roof had stopped working, and it could not be fixed. Desperate for a solution, their mother called five broadband companies, trying to get connections for their home in Orrum, N.C., a rural community of fewer than 100 people with no grocery store or traffic lights. All the companies gave the same answer: Service is not available in your area. The response is the same across broad stretches of Robeson County, N.C., a swath of small towns and rural places like Orrum dotted among soybean fields and hog farms on the South Carolina border. About 20,000 of the county's homes, or 43 percent of all households, have no internet connection.

The technology gap has prompted teachers to upload lessons on flash drives and send them home to dozens of students every other week. Some children spend school nights crashing at more-connected relatives' homes so they can get online for classes the next day. [...] Millions of American students are grappling with the same challenges, learning remotely without adequate home internet service. Even as school districts like the one in Robeson County have scrambled to provide students with laptops, many who live in low-income and rural communities continue to have difficulty logging on. "About 15 million K-12 students lived in households without adequate online connectivity in 2018," the report notes, citing a study of federal data by Common Sense Media, an education nonprofit group that tracks children's media use.

"[T]he pandemic turned the lack of internet connectivity into a nationwide emergency: Suddenly, millions of schoolchildren were cut off from digital learning, unable to maintain virtual 'attendance' and marooned socially from their classmates."

Australia's climate has entered a new era of sustained extreme weather events, such as dangerous bushfires and heatwaves, courtesy of rising average temperatures, a new report by the nation's two government climate science agencies has found. From a report: Rising levels of carbon dioxide in the atmosphere, mostly from fossil fuel burning, has driven more dangerous bushfires, rising sea levels and a rapid rise in the days where temperatures reach extreme levels, the Bureau of Meteorology and the CSIRO said in Australia's latest State of the Climate Report. "What we are seeing now is beyond the realm of what was possible previously," said Dr Jaci Brown, director of CSIRO's Climate Science Centre.

While 2019 was Australia's hottest on record that helped deliver unprecedented bushfires, those temperatures would be seen as average once global heating reaches 1.5C, the report said. Among the key findings, the report said Australia's climate had warmed by 1.44C since 1910 with bushfire seasons getting longer and more dangerous. Australia's oceans had warmed by 1C and were acidifying. In a briefing to reporters on Tuesday, Dr Karl Braganza, manager of climate environmental prediction service at the bureau, said conditions in Australia were in line with projections over recent decades. But he said: "What we are seeing now is a more tangible shift in the extremes and we are starting to feel how that shift in the average is impacting on extreme events. So we don't necessarily feel that 1.44C increase in average temperature, but we do feel those heatwaves and we feel that fire weather."

A potential hostage situation is reportedly taking place at the building in which game developer Ubisoft's Montreal office is housed. From a report: A group of suspects are reportedly holding tens of people hostage at Ubisoft Montreal, according to local (French-language) media outlet LCN. The situation reportedly began around 1:30pm Eastern Time. Montreal police confirmed that there is an "ongoing police operation" at the intersection where Ubisoft Montreal sits, adding, "We ask people to avoid the area. The SPVM is currently validating information and more details will follow." [...] When asked about the reports, an Ubisoft representative offered the following statement to Ars Technica: "We are aware of the situation and working with local authorities." Updated at 22:41, November 13: Police said no threat had yet been found, and CBC News reported that the incident had been caused by a hoax 911 call.

YouTube says it will not produce its annual end-of-year "Rewind" video this year, due to the global pandemic. The BBC reports: The video-sharing platform has produced an annual retrospective since 2010, featuring well-known YouTube stars referencing big viral moments. But, in a statement it said: "2020 has been different. And it doesn't feel right to carry on as if it weren't."

Journalist Chris Stokel-Walker, who writes about YouTube and other social platforms, said it was a shame that Rewind had been cancelled because YouTube had become "a major source of entertainment and support for people during the pandemic." But he added: "There's just not that much new that's come out of YouTube this year. It's been outmoded and overtaken as the place that trends begin, by more nimble apps like TikTok. "Rewind has always featured a similar cast of characters since it started in 2010, but the potential list of people they could feature would look even more stale in 2020 in comparison to other platforms."

"Help us bring two villages together through the power of code! [...] You will experience empathy and compassion for your neighbor while embracing the diversity that makes us all uniquely special." Intended for ages 7-and-up, the accompanying Educator Guide suggests opening the 45-minute coding lesson (using Blocks or Python) with a 10-minute discussion of unconscious and conscious bias, including "prejudice based on race, ethnicity, age, gender, gender identity, physical ability, religion, and body weight." The Guide also suggests how teachers might explain to students the harm biases can cause: "Both conscious and unconscious biases can cause us to behave negatively or discriminate against people. When we stereotype people based on their gender, ethnicity, sexual orientation, or some other characteristic, it can be detrimental to us and our community. On a larger and extreme scale, bias can lead to oppression, genocide, and even slavery." The Guide notes that this year's Hour of Code lesson adheres to five Social Justice Standards. The use of Minecraft, Microsoft Education suggests, will help keep students developing and applying social and emotional skills during the pandemic.
