10:00a	Someone Called the Cops On Their Own Smart Vacuum According to Sacramento CBS affiliate KOVR-TV, Yana Sydnor called the police to report a possible home invasion. Turns out, it was a robovac that her son turned on before leaving for the weekend. Android Police reports: At 1 a.m., she and her 2-year-old daughter woke up to loud booms coming from her stairs disrupting her meditation music. She texted her friends about the sounds before they quickly responded, urging her to call 911. "I hear someone walking down my stairs, so it's like boom, boom, boom, boom, boom," Sydnor recalls telling the dispatcher. Desperate to exit the house and avoid a run-in with the invader, she ran to the bathroom, put her daughter in the tub, and thought about grabbing a ladder to get them both outside to ground level. Officers arrived within 10 minutes of Sydnor's call. They rammed the front door wide open only to find a poor robovac, fresh from a tumble down a flight of stairs. "My son turned on the vacuum cleaner because he didn't want to do chores before he left for the weekend," she explained to the reporter after a moment of exasperated silence. The vacuum hadn't been used for 2 years and, even after the fall, it still works. We couldn't make out the make and model of the robovac, so we don't quite know if it could stop itself from going over the ledge much less what exactly happened in this case if it did have the ability.

1:00p	TSMC Founder Says China's Semiconductor Industry Still Five Years Behind An anonymous reader quotes a report from South China Morning Post: In a rare public appearance since retiring nearly three years ago, Morris Chang, the 89-year-old founder of the world's largest contract chip maker, said China is not yet a competitor in chipmaking and that Taiwan should defend its leadership in semiconductor manufacturing. "Mainland China has given out subsidies to the tune of tens of billions of US dollars over the past 20 years but it is still five years behind TSMC," Chang said. "Its logic chip design capability is still one to two years behind the US and Taiwan. The mainland is still not yet a competitor." In his speech, Chang also took a swipe at US chip giant Intel, describing its recent decision to enter the contract chip making market as "very ironic" because it turned down an opportunity to invest in TSMC more than three decades ago. Contract chip makers like TSMC typically take orders from so-called fabless chip makers like Qualcomm, which design their products but outsource the manufacturing. Chang said he was rejected by Intel when he approached it for funding in 1985. "In the past, Intel was the alpha sneering at us and thought that we would never get big," he said. "They never thought the business of [outsourced] wafer fabrication would become so important today." Chang said the US is also at a disadvantage compared with Taiwan because it lacks engineers dedicated to the semiconductor manufacturing sector, adding that the "US level of dedication to manufacturing was absolutely no match for that of Taiwan." "What I need right now are capable and dedicated engineers, technicians and operators. And they have to be willing to throw themselves into manufacturing," he said. "In the US, doing manufacturing isn't popular. It hasn't been popular for decades." Read more of this story at Slashdot. (Comment on this)
5:34p	Elon Musk, Jack Dorsey Argue that Bitcoin Incentivises Renewable Energy Jack Dorsey, the co-founder and CEO of Twitter, tweeted Wednesday that bitcoin "incentivises renewable energy." And Elon Musk responded "True." The BBC adds that the tweets came "despite experts warning otherwise." The cyrptocurrency's carbon footprint is as large as some of the world's biggest cities, studies suggest. But Mr Dorsey claims that could change if bitcoin miners worked hand-in-hand with renewable energy firms. One expert said it was a "cynical attempt to greenwash" bitcoin. China, where more than two-thirds of power is from coal, accounts for more than 75% of bitcoin mining around the world... The tweet comes soon after the release of a White Paper from Mr Dorsey's digital payment services firm Square, and global asset management business ARK Invest. Entitled "Bitcoin as key to an abundant, clean energy future", the paper argues that "bitcoin miners are unique energy buyers", because they offer flexibility, pay in a cryptocurrency, and can be based anywhere with an internet connection. "By combining miners with renewables and storage projects, we believe it could improve the returns for project investors and developers, moving more solar and wind projects into profitable territory," it said. Author and bitcoin critic David Gerard described the paper as a "cynical exercise in bitcoin greenwashing". "The reality is: bitcoin runs on coal," he told the BBC.... "Bitcoin mining is so ghastly and egregious that the number one job of bitcoin promoters is to make excuses for it — any excuse at all." Read more of this story at Slashdot. (Comment on this)
