17-Year-Old Beats Magnus Carlsen in World Rapid Chess Championship

Each player gets 15 minutes for all moves (plus a 10-second-per-move increment) at the World Rapid Chess Championship.

But players only get three minutes for all moves (plus a 2-second-per-move increment) in the World Blitz Chess Championship.

So what happened? World chess champion Magnus Carlsen entered both events, and…

A little-known 17-year-old from Uzbekistan made a clean sweep of Magnus Carlsen and the global chess elite on Tuesday, incidentally setting a world age record. Nodirbek Abdusattorov won the World Rapid championship in Warsaw, claiming en route the scalps of Magnus Carlsen and the No 1’s last two challengers, Fabiano Caruana and Ian Nepomniachtchi…

After 21 rounds of three-minute games on Wednesday and Thursday, France’s Maxime Vachier-Lagrave defeated Poland’s Jan-Krzysztof Duda in a tie-break to win the World Blitz title. The 18-year-old world No 2, Alireza Firouzja, was third but Carlsen was well adrift in 12th place. He said: “Some days you just don’t have it. I was nowhere near close to the level I needed to be today.”

At 17 years three months Abdusattorov becomes the youngest ever world champion in open competition… After 13 rounds he was in a quadruple tie on 9.5 points with Carlsen, Caruana and Nepomniachtchi, but the regulations excluded Carlsen and Caruana from the play-off due to their inferior tie-breaks. An angry Carlsen denounced the rules as “idiotic. Either all players on the same amount of points join the play-off or no one does…”

[In the final play-off game] Abdusattorov easily drew with Black, then won the second game despite twice missing mate in two near the end.

‘A Quadrillion Mainframes On Your Lap’

“Your laptop is way more powerful than you might realize,” writes long-time Slashdot reader fahrbot-bot.
“People often rhapsodize about how much more computer power we have now compared with what was available in the 1960s during the Apollo era. Those comparisons usually grossly underestimate the difference.”

Rodney Brooks, emeritus professor of robotics at MIT (and former director of their AI Lab and CSAIL) explains in IEEE Spectrum:

By 1961, a few universities around the world had bought IBM 7090 mainframes. The 7090 was the first line of all-transistor computers, and it cost US $20 million in today’s money, or about 6,000 times as much as a top-of-the-line laptop today. Its early buyers typically deployed the computers as a shared resource for an entire campus. Very few users were fortunate enough to get as much as an hour of computer time per week.

The 7090 had a clock cycle of 2.18 microseconds, so the operating frequency was just under 500 kilohertz. But in those days, instructions were not pipelined, so most took more than one cycle to execute. Some integer arithmetic took up to 14 cycles, and a floating-point operation could hog up to 15. So the 7090 is generally estimated to have executed about 100,000 instructions per second. Most modern computer cores can operate at a sustained rate of 3 billion instructions per second, with much faster peak speeds. That is 30,000 times as fast, so a modern chip with four or eight cores is easily 100,000 times as fast.

Unlike the lucky person in 1961 who got an hour of computer time, you can run your laptop all the time, racking up more than 1,900 years of 7090 computer time every week….

But, really, this comparison is unfair to today’s computers. Your laptop probably has 16 gigabytes of main memory. The 7090 maxed out at 144 kilobytes. To run the same program would require an awful lot of shuffling of data into and out of the 7090 — and it would have to be done using magnetic tapes . The best tape drives in those days had maximum data-transfer rates of 60 KB per second. Although 12 tape units could be attached to a single 7090 computer, that rate needed to be shared among them. But such sharing would require that a group of human operators swap tapes on the drives; to read (or write) 16 GB of data this way would take three days. So data transfer, too, was slower by a factor of about 100,000 compared with today’s rate.

So now the 7090 looks to have run at about a quadrillionth (10 ** -15) the speed of your 2021 laptop. A week of computing time on a modern laptop would take longer than the age of the universe on the 7090.

Sugar Additive Trehalose Could Have Helped Spread Dangerous Superbug Around the US

A sugar additive used in several foods could have helped spread a seriously dangerous superbug around the US, according to a 2018 study. ScienceAlert reports: The finger of blame is pointed squarely at the sugar trehalose, found in foods such as nutrition bars and chewing gum. If the findings are confirmed, it’s a stark warning that even apparently harmless additives have the potential to cause health issues when introduced to our food supply. In this case, trehalose is being linked with the rise of two strains of the bacterium Clostridium difficile, capable of causing diarrhea, colitis, organ failure, and even death. The swift rise of the antibiotic-resistant bug has become a huge problem for hospitals in recent years, and the timing matches up with the arrival of trehalose.

“In 2000, trehalose was approved as a food additive in the United States for a number of foods from sushi and vegetables to ice cream,” said one of the researchers, Robert Britton from the Baylor College of Medicine in Texas, back in January 2018. “About three years later the reports of outbreaks with these lineages started to increase. Other factors may also contribute, but we think that trehalose is a key trigger.”

The C. difficile lineages Britton is referring to are RT027 and RT078. When the researchers analysed the genomes of these two strains, they found DNA sequences that enabled them to feed off low doses of trehalose sugar very efficiently. In fact, these particular bacteria need about 1,000 times less trehalose to live off than other varieties of C. difficile, thanks to their genetic make-up. […] It’s still not certain that trehalose has contributed to the rise of C. difficile, but the study results and the timing of its approval as an additive are pretty compelling. More research will now be needed to confirm the link. According to figures from the CDC, “C. difficile was responsible for half a million infections across the year and 29,000 deaths within the first 30 days of diagnosis,” adds ScienceAlert. The findings were published in the journal Nature.

Approval For AMD’s $35 Billion Xilinx Acquisition Slips To 2022

AMD’s $35 billion acquisition of Xilinx is now expected to close in the first quarter of 2022, which is a few months after AMD and Xilinix’s originally proposed closing of the deal before the end of 2021. Tom’s Hardware reports: AMD has cleared regulatory hurdles in all but China. News filtered out earlier this month that AMD has filed certain undefined ‘behavioral remedies’ to appease Chinese regulators, and mid-month found news that China’s antitrust agency, the State Administration for Market Regulation (SAMR), was still market-testing AMD’s proposed remedies.

Here’s AMD’s statement on the matter: “We continue making good progress on the required regulatory approvals to close our transaction. While we had previously expected that we would secure all approvals by the end of 2021, we have not yet completed the process and we now expect the transaction to close in the first quarter of 2022. Our conversations with regulators continue to progress productively, and we expect to secure all required approvals. There are no additional changes to the previously announced terms or plans regarding the transaction and the companies continue to look forward to the proposed combination creating the industry’s high-performance and adaptive computing leader.”

Boston Dynamics’ Stretch Can Move 800 Heavy Boxes Per Hour

Stretch is a new robot from Boston Dynamics that can move approximately 800 heavy boxes per hour. As IEEE Spectrum reports, it’s part of “a new generation of robots with the intelligence and flexibility to handle the kind of variation that people take in stride.” From the report: Stretch’s design is somewhat of a departure from the humanoid and quadrupedal robots that Boston Dynamics is best known for, such as Atlas and Spot. With its single massive arm, a gripper packed with sensors and an array of suction cups, and an omnidirectional mobile base, Stretch can transfer boxes that weigh as much as 50 pounds (23 kilograms) from the back of a truck to a conveyor belt at a rate of 800 boxes per hour. An experienced human worker can move boxes at a similar rate, but not all day long, whereas Stretch can go for 16 hours before recharging. And this kind of work is punishing on the human body, especially when heavy boxes have to be moved from near a trailer’s ceiling or floor.

“Truck unloading is one of the hardest jobs in a warehouse, and that’s one of the reasons we’re starting there with Stretch,” says Kevin Blankespoor, senior vice president of warehouse robotics at Boston Dynamics. Blankespoor explains that Stretch isn’t meant to replace people entirely; the idea is that multiple Stretch robots could make a human worker an order of magnitude more efficient. “Typically, you’ll have two people unloading each truck. Where we want to get with Stretch is to have one person unloading four or five trucks at the same time, using Stretches as tools.” All Stretch needs is to be shown the back of a trailer packed with boxes, and it’ll autonomously go to work, placing each box on a conveyor belt one by one until the trailer is empty. People are still there to make sure that everything goes smoothly, and they can step in if Stretch runs into something that it can’t handle, but their full-time job becomes robot supervision instead of lifting heavy boxes all day.

Stretch is optimized for moving boxes, a task that’s required throughout a warehouse. Boston Dynamics hopes that over the longer term the robot will be flexible enough to put its box-moving expertise to use wherever it’s needed. In addition to unloading trucks, Stretch has the potential to unload boxes from pallets, put boxes on shelves, build orders out of multiple boxes from different places in a warehouse, and ultimately load boxes onto trucks, a much more difficult problem than unloading due to the planning and precision required. […] Boston Dynamics spent much of 2021 turning Stretch from a prototype, built largely from pieces designed for Atlas and Spot, into a production-ready system that will begin shipping to a select group of customers in 2022, with broader sales expected in 2023. For Blankespoor, that milestone will represent just the beginning. He feels that such robots are poised to have an enormous impact on the logistics industry.

Retailers Surrender To Unprecedented Costs On Online Returns

Returning unwanted gifts this holiday season is becoming so expensive for retailers that they just might let customers keep the products — and issue refunds anyway. Axios reports: The cost of online returns is soaring, contributing to increased prices, product shortages and supply chain stress. Returning a $50 item is expected to cost an average of $33, up 59% from 2020, according to Optoro, a returns processor. Worker shortages and supply chain problems are taking a toll, Optoro CEO Tobin Moore tells Axios. About three in 10 online purchases are returned, according to CBRE Supply Chain.

Retailers are expected to pass on the cost of returns in the form of higher prices. “The consumer pays the price of a free return,â Columbia Business School retail studies professor Mark Cohen told Today. Some retailers, namely Amazon, sometimes tell returners to keep it. It would cost them too much to process a return, Moore says. The challenge for online retailers is to process returns quickly and get the goods back onto their virtual shelves, minimizing depreciation. “The faster you can get a good back to stock, the more you can avoid markdowns,” Moore says.

California Is Suing Walmart Over Alleged Improper Disposal of E-Waste and Other Hazardous Materials

Last week, the California attorney general and 12 state officials filed a lawsuit against Walmart, saying it allegedly illegally disposed of electronic and hazardous waste, compromising local landfills. The Verge reports: California Attorney General Rob Bonta alleges in a statement the company violated state environmental laws with their practices, and the waste included materials like lithium and alkaline batteries, insect killer sprays, aerosol cans, LED lightbulbs, and more. State investigators conducted 58 inspections across 13 counties from 2015 to 2021 and said they found classified hazardous and medical waste in each store’s trash compactors, as well as customer information that should have been rendered indecipherable. The California DOJ estimates that Walmart’s unlawfully disposed waste totals 159,600 pounds or more than 1 million items each year.

State investigators conducted 58 inspections across 13 counties from 2015 to 2021 and said they found classified hazardous and medical waste in each store’s trash compactors, as well as customer information that should have been rendered indecipherable. The California DOJ estimates that Walmart’s unlawfully disposed waste totals 159,600 pounds or more than 1 million items each year. Hargrove said that the compactor waste audits “conducted or overseen by the California attorney general have shown that the compactor waste contain at most 0.4% of items of potential concern,” comparing it to the 3 percent statewide average. In 2010, Walmart reached a $25 million settlement with the state of California for illegally disposing of hazardous waste. They also paid $1.25 million to Missouri in 2012 for a similar incident and pleaded guilty in 2013 for negligently discharging a pollutant into drains in 16 counties in California.

Hyundai Shuts Down Its Engine Development Team Amid Focus On Electric Cars

Hyundai announced that it is shutting down its internal combustion engine development team as the automaker focuses on electric cars. Electrek reports: For 40 years the Korean automaker has been developing internal combustion engines to use in its vehicle lineup, but no more. The Korea Economic Daily reports that Hyundai’s new R&D chief Park Chung-kook confirmed in an email to employees that they are shutting down new engine development: “Now, it is inevitable to convert into electrification. Our own engine development is a great achievement, but we must change the system to create future innovation based on the great asset from the past.”

Hyundai reportedly had 12,000 people working on engines, but they are now being transferred to EV powertrain development: “Researchers at the engine design unit have moved to the electrification design center, leaving only some to modify existing engines. The powertrain system development center is transforming into an electrification test center, while the powertrain performance development center is becoming an electrification performance development center.” Park added on the change: “The immediate task is to develop innovative vehicles that can dominate the future market. This reorganization will be an important starting point for change ahead in the new year.”

X-ray Analysis Confirms Forged Date On Lincoln Pardon of Civil War Soldier

U.S. President Abraham Lincoln pardoned a soldier in the Civil War, and in 1998 that document was re-discovered. But “It was the date that made the document significant,” writes Ars Technica: April 14, 1865, “meaning the pardon was likely one of the last official acts of President Lincoln, since he was assassinated later that same day at Ford’s Theater in Washington, D.C. The pardon was broadly interpreted as evidence for a historical narrative about the president’s compassionate nature: i.e., his last act was one of mercy.”

But now scientists at America’s National Archives have conducted a new analysis (published in the journal Forensic Science International: Synergy), and “confirmed that the date was indeed forged (although the pardon is genuine).”
An archivist named Trevor Plante became suspicious of the document, noting that the ink on the “5” in “1865” was noticeably darker. It also seemed as if another number was written underneath it. Then Plante consulted a seminal collection of Lincoln’s writings from the 1950s. The pardon was there, but it was dated April 14, 1864 — a full year before Lincoln was assassinated by John Wilkes Booth. Clearly the document had been altered sometime between the 1950s and 1998 to make the pardon more historically significant..

Investigators naturally turned to the man who made the discovery for further information. They began corresponding with Thomas Lowry [a retired psychiatrist turned amateur historian] in 2010. Initially, Lowry seemed cooperative, but when he learned about the nature of the investigation, he stopped communicating with the Office of the Inspector General, thereby arousing suspicion. So the investigators knocked on the historian’s door one January morning in 2011 for an interview. Shortly thereafter, the National Archives released a statement that Lowry had confessed to altering the date on the pardon. Lowry confessed to bringing a fountain pen into the research room, along with fade proof, pigment-based ink, and changing the “4” in “1864” to a “5.” Lowry couldn’t be charged with any crime because the statute of limitations for tampering with government property had run out, but he was barred from the National Archives for life.
But there’s a twist: Lowry soon recanted, claiming he had signed the confession under duress from the National Archives investigators…

Long-time Slashdot reader waspleg writes that Ars Technica “goes through the analysis of how it was verified to be a forgery using several techniques,” including ultraviolet light and X-ray fluorescence analysis to study chemicals in the ink. From the article:

An examination under magnification and reflective fiber optic lighting showed the ink used to write the “5” was indeed different in overall color compared to the other numbers in the date. Furthermore, “Vestiges of ink from a scratched away number can be seen below and beside the darker ‘5,’ as well as smeared across the paper,” the authors wrote. Additional analysis under raking light — a technique that accentuates hills and valleys in the paper texture — revealed abrasions to the paper under and around the “5” that were not observed anywhere else on the document. The team also determined that the paper around the “5” is thinner than everywhere else, and that ink residue of the scratched-away “4” were caught in the abraded paper fibers, clearly visible using transmitted light microscopy…

“The authors also concluded that there is no way to restore the document to its original state without causing further damage.”
