Singapore is set to host the world's first electric-powered air taxi service by the end of 2023, according to Volocopter GmbH, which is developing the vertical-takeoff craft. From a report: The German manufacturer is committed to starting operations within three years once it completes flight trials, evaluation and certification in collaboration with the city-state, it said in a statement Wednesday. Tickets for a 15-minute trip costing 300 euros ($364) are already on sale. Volocopter completed a demonstration flight over Singapore's Marina Bay area in October last year, and the first commercial route is likely to fly tourists over the same district, offering spectacular views of the skyline, the company said. Later services could including cross-border journeys. Singapore is at the forefront of plans to introduce flying taxis thanks to a more welcoming regulatory regime than in some other countries. While the craft could replace helicopters and light aircraft on some routes, they'd also be small and nimble enough to fly deep within cities and land with minimal space. "Singapore is renowned for its leading role in adapting and living new technologies," Volocopter Chief Executive Officer Florian Reuter said, adding that local capabilities in battery research, material science and route validation for autonomous operations will be central to the project.

An anonymous reader quotes a report from Ars Technica: A grand jury in California's Santa Clara County has indicted Thomas Moyer, Apple's head of global security, for bribery. Moyer is accused of offering 200 iPads to the Santa County Sheriff's office in exchange for concealed carry permits for four Apple employees. Moyer's attorney says that he did nothing wrong, and notably Apple is standing behind its executive. "We expect all of our employees to conduct themselves with integrity," an Apple spokesperson said in a statement. "After learning of the allegations, we conducted a thorough internal investigation and found no wrongdoing."

Also indicted were two officials in the office of Santa Clara County Sheriff Laurie Smith. These officials are accused of soliciting the alleged bribe. California law gives sheriffs broad discretion to decide who gets permits to carry concealed weapons in the state. Smith has previously faced accusations that her office deliberately withheld permits to carry concealed weapons until applicants did favors for Smith. A June investigation by NBC Bay Area found that donors to Smith's re-election campaign were 14 times more likely to get concealed carry permits than those who didn't donate. A press release from Smith's office described the indictments as "a difficult time for our organization."

Jeff Rosen, the Santa Clara district attorney responsible for the indictments, said that the donation of 200 iPads was scuttled at the last minute after Rosen obtained a search warrant in the case. According to LinkedIn, Moyer is responsible for "strategic management of Apple's corporate and retail security, crisis management, executive protection, investigations and new product secrecy." While two individuals in Sheriff Smith's office were indicted, no charges have been filed against Smith herself. Rosen says the investigation is ongoing. A common prosecutorial strategy is to focus on lower-ranking employees first in order to pressure them to provide evidence against their boss.

In some of the most remote and impoverished corners of the world, where respiratory illnesses abound and trained medical professionals fear to tread, diagnosis is increasingly powered by artificial intelligence and the internet. From a report: In less than a minute, a new app on a phone or a computer can scan an X-ray for signs of tuberculosis, Covid-19 and 27 other conditions. TB, the most deadly infectious disease in the world, claimed nearly 1.4 million lives last year. The app, called qXR, is one of many A.I.-based tools that have emerged over the past few years for screening and diagnosing TB. The tools offer hope of flagging the disease early and cutting the cost of unnecessary lab tests. Used at large scale, they may also spot emerging clusters of disease.

"Among all of the applications of A.I., I think digitally interpreting an image using an algorithm instead of a human radiologist is probably furthest along," said Madhukar Pai, the director of the McGill International TB Center in Montreal. Artificial intelligence cannot replace clinicians, Dr. Pai and other experts cautioned. But the combination of A.I. and clinical expertise is proving to be powerful. "The machine plus clinician is better than the clinician, and it's also better than machine alone," said Dr. Eric Topol, the director of the Scripps Research Translational Institute in San Diego and the author of a book on the use of A.I. in medicine. In India, where roughly one-quarter of the world's TB cases occur, an app that can flag the disease in remote locations is urgently needed.

An anonymous reader quotes a report from The New York Times: The Trump administration on Monday announced that it would begin the formal process of selling leases to oil companies in a last-minute push to achieve its long-sought goal of allowing oil and gas drilling in the Arctic National Wildlife Refuge in Alaska. That sets up a potential sale of leases just before Jan. 20, Inauguration Day, leaving the new administration of Joseph R. Biden Jr., who has opposed drilling in the refuge, to try to reverse them after the fact.

The Arctic refuge is one of the last vast expanses of wilderness in the United States, 19 million acres that for the most part are untouched by people, home instead to wandering herds of caribou, polar bears and migrating waterfowl. It has long been prized, and protected, by environmentalists, but President Trump has boasted that opening part of it to oil development was among the most significant of his efforts to expand domestic fossil fuel production. The Federal Register on Monday posted a "call for nominations" from the Bureau of Land Management, to be officially published Tuesday, relating to lease sales in about 1.5 million acres of the refuge along the coast of the Arctic Ocean. A call for nominations is essentially a request to oil companies to specify which tracts of land they would be interested in exploring and potentially drilling for oil and gas.

The administration's announcement establishes a tight timeline for lease sales, with the earliest they could occur being on or about Jan. 17. The call for nominations will allow for comments until Dec. 17, after which the bureau, part of the Interior Department, could issue a final notice of sales to occur as soon as 30 days later. Normally the bureau would take time to review the comments and determine which tracts to sell before issuing the final notice of sale, a process that can take several months. In this case, however, the bureau could decide to make the entire coastal plain available and issue the notice immediately. Any sales would be subject to review by agencies in the Biden administration, including the bureau and the Justice Department, a process that could take a month or two. That could allow the Biden White House to refuse to issue the leases, perhaps by claiming that the scientific underpinnings of the plan to allow drilling in the refuge were flawed, as environmental groups have claimed.

Last week, Apple released macOS Big Sur and the rollout was anything but smooth. The mass upgrade caused the Apple servers responsible for checking if a user opens an app not downloaded from the App Store to slow to a crawl. Apple eventually fixed the problem, "but concerns about paralyzed Macs were soon replaced by an even bigger worry -- the vast amount of personal data Apple, and possibly others, can glean from Macs performing certificate checks each time a user opens an app that didn't come from the App Store," writes Dan Goodin via Ars Technica. From the report: Before Apple allows an app into the App Store, it must first pass a review that vets its security. Users can configure the macOS feature known as Gatekeeper to allow only these approved apps, or they can choose a setting that also allows the installation of third-party apps, as long as these apps are signed with a developer certificate issued by Apple. To make sure the certificate hasn't been revoked, macOS uses OCSP -- short for the industry standard Online Certificate Status Protocol -- to check its validity. [...] Somehow, the mass number of people upgrading to Big Sur on Thursday seems to have caused the servers at ocsp.apple.com to become overloaded but not fall over completely. The server couldn't provide the all clear, but it also didn't return an error that would trigger the soft fail. The result was huge numbers of Mac users left in limbo.

The post Your Computer Isn't Yours was one of the catalysts for the mass concern. It noted that the simple HTML get-requests performed by OCSP were unencrypted. That meant that not only was Apple able to build profiles based on our minute-by-minute Mac usage, but so could ISPs or anyone else who could view traffic passing over the network. (To prevent falling into an infinite authentication loop, virtually all OCSP traffic is unencrypted, although responses are digitally signed.) Fortunately, less alarmist posts like this one provided more helpful background. The hashes being transmitted weren't unique to the app itself but rather the Apple-issued developer certificate. That still allowed people to infer when an app such as Tor, Signal, Firefox, or Thunderbird was being used, but it was still less granular than many people first assumed. The larger point was that, in most respects, the data collection by ocsp.apple.com wasn't much different from the information that already gets transmitted in real time through OCSP every time we visit a website. [...] In short, though, the takeaway was the same: the potential loss of privacy from OCSP is a trade-off we make in an effort to check the validity of the certificate authenticating a website we want to visit or a piece of software we want to install.

In an attempt to further assure Mac users, Apple on Monday published this post. It explains what the company does and doesn't do with the information collected through Gatekeeper and a separate feature known as notarization, which checks the security even of non-App Store apps. The post went on to say that in the next year, Apple will provide a new protocol to check if developer certificates have been revoked, provide "strong protections against server failure," and present a new OS setting for users who want to opt out of all of this. [...] People who don't trust OCSP checks for Mac apps can turn them off by editing the Mac hosts file. Everyone else can move along.

You may have noticed a rash of provocative headlines this week suggesting that mouthwash can "inactivate" coronaviruses and help curb their spread. While the news is based on a new study from researchers at the Penn State College of Medicine, it's important to note that the study focused on a coronavirus that causes common colds -- not the one that causes COVID-19. "Not only did the study not investigate this deadly new virus, but it also did not test whether mouthwash affects how viruses spread from person to person," adds Katherine J. Wu via The New York Times. From the report: "I don't have a problem with using Listerine," said Angela Rasmussen, a virologist at Columbia University. "But it's not an antiviral." The study, which was published last month in the Journal of Medical Virology, looked only at a coronavirus called 229E that causes common colds -- not the new coronavirus, which goes by the formal name of SARS-CoV-2, and causes far more serious disease. Researchers can study SARS-CoV-2 only in high-security labs after undergoing rigorous training. The two viruses are in the same family, and, in broad strokes, look anatomically similar, which can make 229E a good proxy for SARS-CoV-2 in certain experiments. But the two viruses shouldn't be thought of as interchangeable, Dr. Rasmussen said.

The researchers tested the virus-destroying effects of several products, including a watered-down mixture of Johnson's baby shampoo -- which is sometimes used to flush out the inside of the nose -- and mouthwashes made by Listerine, Crest, Orajel, Equate and C.V.S. They flooded 229E coronaviruses, which had been grown in human liver cells in the lab, with these chemicals for 30 seconds, 1 minute or 2 minutes -- longer than the typical swig or spritz into a nose or mouth. Around 90 to 99 percent of the viruses could no longer infect cells after this exposure, the study found.

But because the study didn't recruit any human volunteers to gargle the products in question, the findings have limited value for the real world, other experts said. The human mouth, full of nooks and crannies and a slurry of chemicals secreted by a diverse cadre of cells, is far more complicated than the inside of a laboratory dish. Nothing should be considered conclusive "unless human studies are performed," said Dr. Maricar Malinis, an infectious disease expert at Yale University. [...] Even if people did a very thorough job coating the inside of their mouths or noses with a coronavirus-killing chemical, a substantial amount of the virus would still remain in the body. The new coronavirus infiltrates not only the mouth and nose, but also the deep throat and lungs, where mouthwash and nasal washes hopefully never enter. Viruses that have already hidden away inside cells will also be shielded from the fast-acting chemicals found in these products.

"Facing the prospect that President Trump could lose his re-election bid, his cabinet is scrambling to enact regulatory changes affecting millions of Americans in a blitz so rushed it may leave some changes vulnerable to court challenges," reports the New York Times: The effort is evident in a broad range of federal agencies and encompasses proposals like easing limits on how many hours some truckers can spend behind the wheel, giving the government more freedom to collect biometric data and setting federal standards for when workers can be classified as independent contractors rather than employees. In the bid to lock in new rules before Jan. 20, Mr. Trump's team is limiting or sidestepping requirements for public comment on some of the changes and swatting aside critics who say the administration has failed to carry out sufficiently rigorous analysis. Some cases, like a new rule to allow railroads to move highly flammable liquefied natural gas on freight trains, have led to warnings of public safety threats...

If Democrats take control of Congress, they will have the power to reconsider some of these last-minute regulations, through a law last used at the start of Mr. Trump's tenure by Republicans to repeal certain rules enacted at the end of the Obama administration. But the Trump administration is also working to fill key vacancies on scientific advisory boards with members who will hold their seats far into the next presidential term, committees that play an important role in shaping federal rule making...

The Homeland Security Department is also moving, again with an unusually short 30-day comment period, to adopt a rule that will allow it to collect much more extensive biometric data from individuals applying for citizenship, including voice, iris and facial recognition scans, instead of just the traditional fingerprint scan. The measure, which the agency said was needed to curb fraud, would also allow it for the first time to collect DNA or DNA test results to verify a relationship between an application for citizenship and someone already in the United States.

The source for this story is a post on Reddit, which Jalopnik argues "was corroborated with this remarkable video of Tesla's new Instant, Unplanned Convertible feature." I know we've covered Tesla's chronic quality control issues here before, and I realize that among hardcore Tesla-stans this may feel like we're picking on Tesla unfairly but in our defense, Tesla really does have some terrible quality issues. Sometimes we get a really dramatic and baffling issue, like this one where the fucking roof flew off a brand-new Model Y while the car was being driven home.
"The Tesla service center in Dublin did not return a message seeking comment," reports the Verge, adding "A spokesperson for Tesla also did not respond." Leaving them with nothing but the Redditor's own story: Nathaniel Galicia Chien was driving down Interstate 580 with his parents in their brand-new Tesla Model Y when he started to hear a lot of wind. "I thought a window was open," Chien recalled in an email to The Verge, "but half a minute later the entire glass top of the roof just flew off in the wind."

Chien said the incident occurred hours after he and his parents picked up the new Model Y from the Tesla dealership in Dublin, California. Right off the bat, they noticed some minor "fit and finish" problems, such as "spacing issues and unevenness in the gaps that are pretty well-known issues with new Teslas." But they didn't expect any problems with the crossover's mammoth panoramic glass roof, and certainly not on the same day they drove it off the dealer's lot.

For years, Tesla has been plagued by quality issues, but it seems to have grown worse with the release of the Model Y in 2019. Just this past summer, Tesla scored last in a survey of customers by researcher JD Power. Owners have flocked to online forums to complain about paint and trim problems, indentations in the seats, and loose seatbelts. But an entire roof flying off on the highway is a new kind of problem for Tesla... Chien said Tesla's service representatives said that "either the seal on the roof was faulty, or they somehow just forgot to seal the roof on entirely."
"They gave us a free rental to use in the meantime and offered to get it serviced," the Redditor posted this week, "but we just opted to wait for a brand new one."

AmiMoJo shares a report from the BBC: Shibu Philip admits he knows what it's like to "maybe waste a bit of time at work." Shibu is the founder of Transcend -- a small London-based firm that buys beauty products wholesale and re-sells them online. For the last year and a half he has used Hubstaff software to track his workers' hours, keystrokes, mouse movements and websites visited. With seven employees based in India, he says the software ensures "there is some level of accountability" and helps plug the time difference. "I know myself. [You can] take an extra 10-minute break here or there. It's good to have an automatic way of monitoring what [my employees] are up to," says Shibu. "By looking at screenshots and how much time everyone is taking on certain tasks, I know if they're following procedures. "And, if they're doing better than I expected, I also study the photos and ask them to share that knowledge with the rest of the team so we can all improve," he says.

US-based Hubstaff says its number of UK customers is up four times year-on-year since February. Another company called Sneek offers technology that takes photos of workers through their laptop and uploads them for colleagues to see. Photos can be taken as often as every minute, although it describes itself as a communication platform. Its co-founder, Del Currie, told the BBC that it had seen a five-fold increase in its number of users during lockdown, taking the firm to almost 20,000 in total.

China this week blocked the Wikimedia Foundation's application for observer status at the World Intellectual Property Organization (WIPO), the United Nations (UN) organization that develops international treaties on copyright, IP, trademarks, patents and related issues. As a result of the block, the Foundation's application for observer status has been suspended and will be reconsidered at a future WIPO meeting in 2021. Wikimedia Foundation: China was the only country to raise objections to the accreditation of the Wikimedia Foundation as an official observer. Their last-minute objections claimed Wikimedia's application was incomplete, and suggested that the Wikimedia Foundation was carrying out political activities via the volunteer-led Wikimedia Taiwan chapter. The United Kingdom and the United States voiced support for the Foundation's application. WIPO's work, which shapes international laws and policies that affect the sharing of free knowledge, impacts Wikipedia's ability to provide hundreds of millions of people with information in their own languages. The Wikimedia Foundation's absence from these meetings further separates those people from global events that shape their access to knowledge.

With space junk piling up around our planet, the International Space Station needed to perform a last-minute avoidance maneuver Tuesday to steer clear of an "unknown piece of space debris expected to pass within several kilometers." From a report: Mission Control in Houston conducted the move at 2:19 p.m. PT using the Russian Progress resupply spacecraft docked to the ISS to help nudge the station out of harm's way. "Out of an abundance of caution, the Expedition 63 crew will relocate to their Soyuz spacecraft until the debris has passed by the station," NASA said in a statement prior to the move. The maneuver went off smoothly, NASA administrator Jim Bridenstine reported. "The astronauts are coming out of safe haven," he tweeted after the ISS relocated.

Though the U.S. government averted a shutdown of TikTok through a new Oracle/Walmart partnership, that leaves much bigger questions unresolved. The biggest issue may be that banning apps "defeats the original intent of the internet," argues the New York TImes. "And that was to create a global communications network, unrestrained by national borders." "The vision for a single, interconnected network around the globe is long gone," Jason Healey, a senior research scholar at Columbia University's School for International and Public Affairs and an expert on cyber conflict. "All we can do now is try to steer toward optimal fragmentation."
But the Times also asks whether the TikTok agreement fails even at its original goal of protecting the app from foreign influence: The code and algorithms are the magic sauce that Beijing now says, citing its own national security concerns, may not be exported to to a foreign adversary... Microsoft's bid went further: It would have owned the source code and algorithms from the first day of the acquisition, and over the course of a year moved their development entirely to the United States, with engineers vetted for "insider threats." So far, at least, Oracle has not declared how it would handle that issue. Nor did President Trump in his announcement of the deal. Until they do, it will be impossible to know if Mr. Trump has achieved his objective: preventing Chinese engineers, perhaps under the influence of the state, from manipulating the code in ways that could censor, or manipulate, what American users see.
Other questions also remain, including America's larger policy towards other apps like Telegram made by foreign countries. Even Amy Zegart, a senior fellow at the Hoover Institution and Stanford's Freeman-Spogli Institute, complains to the Times that "bashing TikTok is not a China strategy. China has a multi-prong strategy to win the tech race. It invests in American technology, steals intellectual property and now develops its own technology that is coming into the U.S... And yet we think we can counter this by banning an app. The forest is on fire, and we are spraying a garden hose on a bush."

And another article in the Times argues that the TikTok agreement doesn't even eliminate Chinese ownership of the app: Under the initial terms, ByteDance still controls 80 percent of TikTok Global, two people with knowledge of the situation have said, though details may change. ByteDance's chief executive, Zhang Yiming, will also be on the company's board of directors, said a third person. And the government did not provide specifics about how the deal would answer its security concerns about TikTok...

A news release published by Walmart on Saturday on its website — then edited later — captured the chaos. "This unique technology eliminates the risk of foreign governments spying on American users or trying to influence them with disinformation," the company said. "Ekejechb ecehggedkrrnikldebgtkjkddhfdenbhbkuk."

"President Donald Trump said Saturday he's given his 'blessing' to a proposed deal that would see the popular video-sharing app TikTok partner with Oracle and Walmart and form a U.S. company," reports CBS News: Mr. Trump has targeted Chinese-owned TikTok for national security and data privacy concerns in the latest flashpoint in the rising tensions between Washington and Beijing. The president's support for a deal comes just a day after the Commerce Department announced restrictions that if put in place could eventually make it nearly impossible for TikTok's legions of younger fans to use the app. Mr. Trump said if completed the deal would create a new company likely to be based in Texas...

TikTok said Oracle and Walmart could acquire up to a cumulative 20% stake in the new company in a financing round to be held before an initial public offering of stock, which Walmart said could happen within the next year. Oracle's stake would be 12.5%, and Walmart's would be 7.5%, the companies said in separate statements. The deal will make Oracle responsible for hosting all TikTok's U.S. user data and securing computer systems to ensure U.S. national security requirements are satisfied. Walmart said it will provide its ecommerce, fulfillment, payments and other services to the new company. "We are pleased that the proposal by TikTok, Oracle, and Walmart will resolve the security concerns of the U.S. administration and settle questions around TikTok's future in the U.S.," TikTok said in a statement.
"According to a source close to the matter, ByteDance would keep the rest of the shares," reports a public TV station in Australia. "But since the Chinese company is 40 per cent owned by American investors, TikTok would eventually be majority American-owned."

Today America's Treasury Department told CBS that the deal still needs to close with Oracle and Walmart, and those documents and conditions then need to be approved by government regulatory. But because of today's announcement, "the department said Saturday that it will delay the barring of TikTok from U.S. app stores until Sept. 27 at 11:59 p.m."

While developers have had access to beta versions of the software updates since June, many were caught off guard by Apple's much shorter notice of the final releases. By comparison, Apple started accepting apps built for iOS 13 on September 10 last year, over one week before the software update was released on September 19. From a story yesterday: "I think a lot of developers won't be sleeping tonight or will instead just give up and opt to release [their app] when they want to, instead of alongside the new OS," said iOS developer Shihab Mehboob in a message. "Apple has seemingly out of the blue decided to surprise developers with no real warning or care." [...] "Without advance warning like this, nothing is ready," a developer at High Caffeine Content, Steve Troughton-Smith, told me. "Developers aren't ready, the App Store is't ready, and everybody is rushing to react instead of having the chance to finish their apps properly." Steve ran through the normal iOS release process with me. Apple usually gives third-party app developers a heads up of about a week before the official public release of a new iOS. The company puts out a "Golden Master" copy of the new iOS and Xcode developer tool before the latest operating system is officially released to the public. This gives iPhone app developers the time they need to make sure the apps they've been building for the beta releases of the new iOS actually work on the final version. Sometimes there are critical bugs that are only revealed or could only be fixed at this point in the process.

The extra time can also be used to add new features for any new devices announced at the Apple Event. Apple's approval process for apps also takes some time, so developers have that week to make sure they submit in time to guarantee their work will be in the App Store for the iOS release. "Gone are the hopes of being on the store by the time users install the new iOS 14 and are looking for new apps. Gone is the chance to get some last-minute fixes into your existing apps to make sure they don't stop working outright by the time users get to upgrade their OS," explained Steve. "There are some developers who have spent all summer working on something new, using the latest technologies, hoping to be there on day one and participate in the excitement (and press coverage) of the new iOS," he continued. "For many of them, they'll be incredibly upset to have it end like this instead of a triumphant launch, and it can dramatically decrease the amount of coverage or sales they receive."

Slashdot reader damitr shared IEEE Spectrum's look at Japan's push for flying taxi services: Last year, Spectrum reported on Japan's public-private initiative to create a new industry around electric vertical takeoff and landing vehicles and flying cars. Last Friday [August 28th], start-up company SkyDrive Inc. demonstrated the progress made since then when it held a press conference to spotlight its prototype vehicle and show reporters a video taken three days earlier of the craft undergoing a piloted test flight in front of staff and investors...

In May, SkyDrive unveiled a drone for commercial use that is based on the same drive and power systems as the SD-03. Named the Cargo Drone, it's able to transport payloads of up to 30 kg and can be preprogrammed to fly autonomously or be piloted manually. It will be operated as a service by SkyDrive, starting at a minimum monthly rental charge of 380,000 yen ($3,600) that rises according to the purpose and frequency of use....

Tomohiro Fukuzawa, SkyDrive's CEO, established SkyDrive in 2018 after leaving Toyota Motor and working with Cartivator, a group of volunteer engineers interested in developing flying cars. SkyDrive now has a staff of fifty. Also in 2018, the Japanese government formed the Public-Private Conference for Air Mobility made up of private companies, universities, and government ministries. The stated aim was to make flying vehicles a reality by 2023... Fukuzawa is also targeting 2023 to begin taxi services (single passenger and pilot) in the Osaka Bay area, flying between locations like Kansai and Kobe airports and tourist attractions such as Universal Studios Japan. These flights will take less than ten minutes — a practical nod to the limitations of the battery energy storage system.

"What SkyDrive is proposing is entirely do-able," says Steve Wright, Senior Research Fellow in Avionics and Aircraft Systems at the University of West England. "Almost all rotor-only electric vertical takeoff and landing vehicles projects are limited to sub-30-minute endurance, which, with safety reserves, equate to about 10 to 20 minutes flying."

An anonymous reader quotes a report from Ars Technica: A California judge has granted Uber and Lyft an emergency reprieve from an order requiring them to treat their drivers as employees. The companies were facing a Thursday deadline to comply with the order. Earlier today, Lyft announced that it would be forced to shut down in the state at midnight tonight. Lyft said it was being forced to shut down its California operations by a 2019 California law, AB 5, that forces ride-hailing companies to treat their drivers as employees rather than independent contractors. Uber had warned that it was likely to do the same if the courts didn't delay enforcement of the law.

"This is not something we wanted to do, as we know millions of Californians depend on Lyft for daily, essential trips," Lyft wrote. However, the company said, the new law would "necessitate an overhaul of the entire business model -- it's not a switch that can be flipped overnight." The judge's emergency stay means that Lyft and Uber will be able to keep operating under their current model while they continue litigating whether the new law applies to them. Yesterday, in a podcast interview Uber CEO Dara Khosrowshahi rejected the notion his company is capable of employing all of its drivers in California.

"We can't go out and hire 50,000 people overnight," Khosrowshahi said on the Pivot School podcast hosted by Kara Swisher and Scott Galloway. "Everything that we have built is based on this platform that... brings people who want transportation or delivery together. You can't flip that overnight."

An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission today voted unanimously to lower the prices inmates pay for phone calls from prisons and jails, but the organization reiterated its position that state governments must take action to lower prices on the majority of inmate calls. Today's action is a proposal to "substantially reduce [the FCC's] interstate rate caps -- currently $0.21 per minute for debit and prepaid calls and $0.25 per minute for collect calls -- to $0.14 per minute for debit, prepaid, and collect calls from prisons, and $0.16 per minute for debit, prepaid, and collect calls from jails." This is part of a Notice of Proposed Rulemaking, which means the commission will take public comment before finalizing the new caps and could change the plan before making it final.

Since the proposed rate cap limits prices on interstate calls only, it won't affect the approximately 80 percent of prison calls that don't cross state lines. Last month, FCC Chairman Ajit Pai urged state governments to cap intrastate calling prices, saying the FCC lacks authority to do so. Pai said that "33 states allow rates that are at least double the current federal cap, and 27 states allow excessive 'first-minute' charges up to 26 times that of the first minute of an interstate call." Prison phone companies Global Tel*Link and Securus Technologies have repeatedly challenged FCC-imposed rate limits in court. But while the Obama-era FCC fought in court to lower intrastate rates, Pai in January 2017 instructed FCC lawyers to drop the commission's court defense of the FCC cap on intrastate calling rates. The FCC might have lost that case anyway, as previous court rulings went against the commission. But Pai's decision to drop the court defense helped ensure that the FCC wouldn't be able to cap intrastate rates. The report notes that the FCC also took action to lower some of the "ancillary" fees prison phone companies apply to both interstate and intrastate calls.

"DNA is millions of times more efficient at storing data than your laptop's magnetic hard drive," reports Popular Mechanics.

"Since DNA can store data far more densely than silicon, you could squeeze all of the data in the world inside just a few grams of it." In a new paper published this week in the journal Proceedings of the National Academy of Sciences, Ilya Finkelstein, an associate professor of molecular biosciences at the University of Texas at Austin and company detail their new error correction method... They were able to store the entirety of The Wizard of Oz, translated into Esperanto, with more accuracy than prior DNA storage methods ever could have. We're on the yellow brick road toward the future of data storage.

Researchers at the University of Texas at Austin are certainly not the first to have encoded a work of art onto strands of DNA... [A] team of researchers from Microsoft and the University of Washington fit 200 megabytes of data onto lengths of DNA, including the entirety of War and Peace. In March 2019, they even came up with the first automated system for storing and retrieving data in the manufactured genetic material. Today, other major technology firms are also working in the space, including both IBM and Google. The ultra-secretive U.S. Intelligence Advanced Research Projects Activity — the government's version of DARPA, but for spies — is even invested in the work. These researchers envision a future where some of the most precious, but rarely accessed data, can be stored in vials of DNA, only pulled down from the cool, dark storage of the lab, as needed....

Because there are four building blocks in DNA, rather than the binary 1s and 0s in magnetic hard drives, the genetic storage method is far more dense, explains John Hawkins, another co-author of the new paper. "A teaspoon of DNA contains so much data it would require about 10 Walmart Supercenter-sized data centers to store using current technology," he tells Popular Mechanics. "Or, as some people like to put it, you could fit the entire internet in a shoe box." Not only that, but DNA is future-proof. Hawkins recalls when CDs were the dominant storage method, back in the 1990s, and they held the promise that their storage could last forever, because plastic does (but scratches can be devastating). Data stored on DNA, on the other hand, can last for hundreds of thousands of years. In fact, there is a whole field of science called archaeogenetics that explores the longevity of DNA to understand the ancient past... DNA storage doesn't require any energy, either — just a cool, dark place to hang out until someone decides to access it. But the greatest advantage, Hawkins says, is that our ability to read and write DNA will never become obsolete....

But like all data storage methods, DNA has a few shortcomings as well. The most significant upfront hurdle is cost. Hawkins says that current methods are similar to the cost for an Apple Hard Disk 20 back in 1980. Back then, about 20 megabytes of storage — or the amount of data you'd need to use to download a 15-minute video — went for about $1,500.

An anonymous reader quotes a report from Ars Technica: FCC Chairman Ajit Pai is urging state governments to impose price caps on prison phone calls, three years after Pai helped kill Obama-era FCC rules that limited the price of such calls. Pai yesterday sent a letter to the National Association of Regulatory Utility Commissioners (NARUC), saying it is up to state governments to cap intrastate calling prices because the FCC lacks authority to do so. (NARUC represents state utility regulators.) Pai wrote: "Given the alarming evidence of egregiously high intrastate inmate calling rates and the FCC's lack of jurisdiction here, I am calling on states to exercise their authority and, at long last, address this pressing problem. Specifically, I implore NARUC and state regulatory commissions to take action on intrastate inmate calling services rates to enable more affordable communications for the incarcerated and their families."

Pai's letter did not mention that his own actions helped cement the status quo in which the FCC does not regulate intrastate prices. It's well-established that the FCC can regulate interstate rates, those affecting calls that cross state lines. Pai is even proposing to lower the FCC-imposed rate caps on interstate calls from 25 to 16 per minute in an order the FCC will vote on next month. But Pai's plan doesn't limit prices on intrastate calls, those in which the prisoner and the person on the other end of the line are in the same state. Under then-Chairman Tom Wheeler, the Obama-era FCC did try to limit intrastate prices, but those efforts were repeatedly shot down by court rulings. Shortly after President Trump appointed Pai to replace Wheeler in early 2017, Pai instructed FCC lawyers to drop the commission's court defense of a cap on intrastate calling rates. That helped lead to a June 2017 court victory for prison phone company Global Tel*Link in its lawsuit against the intrastate cap.

The Bitcoin network just fine-tuned a key parameter to coax back miners who quit after last week's halving hammered their profits. From a report: More than 20 exahashes per second (EH/s) of computing power -- the equivalent of around 1.5 million older-generation mining machines -- has been switched off from Bitcoin since the network's halving. The 7-day rolling average of Bitcoin's hash rate has dropped over 20% from around 122 EH/s just prior to the halving on May 11 to now 97 EH/s. The once-in-four-years event reduced miners' block rewards from 12.5 to 6.25 bitcoin (BTC) per block. The hash rate drop after the halving has significantly outrun the hashing sprint prior to it. As such, Bitcoin's mining difficulty, which measures how hard it is to compete for block rewards, decreased 6% to 15.14 Trillion at 2:00 UTC on Wednesday in the network's first biweekly difficulty adjustment since the halving. The amount of computing power connected to Bitcoin has been on a roller-coaster ride over the past two weeks. Bitcoin's mining difficulty adjusts itself every 2,016 blocks, roughly 14 days, to ensure the average interval between blocks remains at 10 minutes. If a large number of miners are switched off from the network, resulting in a longer-than-10-minute average block interval, the difficulty will decrease to encourage participation. And Bitcoin's third halving on May 11 happened exactly at the halfway mark of the previous 2,016-block difficulty cycle.
