Linux 6.0 Arrives With Performance Improvements and More Rust Coming

Linux creator Linus Torvalds has announced the first release candidate for the Linux kernel version 6.0, but he says the major number change doesn’t signify anything especially different about this release. ZDNet: While there is nothing fundamentally different about this release compared with 5.19, Torvalds noted that there were over 13,500 non-merge commits and over 800 merged commits, meaning “6.0 looks to be another fairly sizable release.” According to Torvalds, most of the updates are improvements to the GPU, networking and sound. Torvalds stuck to his word after releasing Linux kernel 5.19 last month, when he flagged he would likely call the next release 6.0 because he’s “starting to worry about getting confused by big numbers again.”

On Sunday’s release of Linux 6.0 release candidate version 1 (rc-1), he explained his reasoning behind choosing a new major version number and its purpose for developers. Again, it’s about avoiding confusion rather than signaling that the release has major new features. His threshold for changing the lead version number was .20 because it is difficult to remember incremental version numbers beyond that. “Despite the major number change, there’s nothing fundamentally different about this release – I’ve long eschewed the notion that major numbers are meaningful, and the only reason for a ‘hierarchical; numbering system is to make the numbers easier to remember and distinguish,” said Torvalds. Torvalds lamented some Rust-enabling code didn’t make it into the release. The Register adds: “I actually was hoping that we’d get some of the first rust infrastructure, and the multi-gen LRU VM, but neither of them happened this time around,” he mused, before observing “There’s always more releases. This is one of those releases where you should not look at the diffstat too closely, because more than half of it is yet another AMD GPU register dump,” he added, noting that Intel’s Gaudi2 Ai processors are also likely to produce plenty of similar kernel additions. “The CPU people also show up in the JSON files that describe the perf events, but they look absolutely tiny compared to the ‘asic_reg’ auto-generated GPU and AI hardware definitions,” he added.

San Francisco Restaurant Claims To Be First To Run Entirely By Robots

Mezli isn’t the first automated restaurant to roll out in San Francisco, but, at least according to its three co-founders, it’s the first to remove humans entirely from the on-site operation equation. Eater SF reports: About two years and a few million dollars later, Mezli co-founders Alex Kolchinski, Alex Gruebele, and Max Perham are days away from firing up the touch screens at what they believe to be the world’s first fully robotic restaurant. To be clear, Mezli isn’t a restaurant in the traditional sense. As in, you won’t be able to pull up a seat and have a friendly server — human, robot, or otherwise — take your order and deliver your food. Instead, Mezli works more like if a vending machine and a restaurant had a robot baby, Kolchinski describes. It’s a way to get fresh food to a lot of people, really fast (the box can pump out about 75 meals an hour), and, importantly, at a lower price; the cheapest Mezli bowl starts at $6.99.

On its face, the concept actually sounds pretty simple. The co-founders built what’s essentially a big, refrigerated shipping container and stuffed it with machines capable of portioning out ingredients, putting those ingredients into bowls, heating the food up, and then moving it to a place where diners can get to it. But in a technical sense, the co-founders say it was quite difficult to work out. Most automated restaurants still require humans in some capacity; maybe people take orders while robots make the food or, vice versa, with automated ordering and humans prepping food behind the scenes. But Mezli can run on its own, serving hundreds of meals without any human staff.

The food does get prepped and pre-cooked off-site by good old-fashioned carbon-based beings. Mezli founding chef Eric Minnich, who previously worked at Traci Des Jardins’s the Commissary and at Michelin-starred Madera at Rosewood Sand Hill hotel, says he and a lean team of just two other people can handle all the chopping, mixing, cooking, and portioning at a commissary kitchen. Then, once a day, they load all the menu components into the big blue-and-white Mezli box. Inside the box, there’s an oven that either brings the ingredients up to temp or finishes up the last of the cooking. Cutting down on labor marks a key cost-saving measure in the Mezli business model; with just a fraction of the staff, as in less than a half dozen workers, Mezli can serve hundreds of meals. “The fully robot-run restaurant begins taking orders and sliding out Mediterranean grain bowls by the end of this week with plans to celebrate a grand opening on August 28 at Spark Social,” notes Eater.

Impact Crater May Be Dinosaur Killer’s Baby Cousin

Researchers have discovered a second impact crater on the other side of the Atlantic that could have finished off what was left of the dinosaurs, after an asteroid known as Chicxulub slammed into what is now the Gulf of Mexico 66 million years ago. The BBC reports: Dubbed Nadir Crater, the new feature sits more than 300m below the seabed, some 400km off the coast of Guinea, west Africa. With a diameter of 8.5km, it’s likely the asteroid that created it was a little under half a kilometre across. The hidden depression was identified by Dr Uisdean Nicholson from Heriot-Watt University, Edinburgh, UK. […] “Our simulations suggest this crater was caused by the collision of a 400m-wide asteroid in 500-800m of water,” explained Dr Veronica Bray from the University of Arizona, US. “This would have generated a tsunami over one kilometre high, as well as an earthquake of Magnitude 6.5 or so. “The energy released would have been around 1,000 times greater than that from the January 2022 eruption and tsunami in Tonga.”

Dr Nicholson’s team has to be cautious about tying the two impacts together. Nadir has been given a very similar date to Chicxulub based on an analysis of fossils of known age that were drilled from a nearby borehole. But to make a definitive statement, rocks in the crater itself would need to be pulled up and examined. This would also confirm Nadir is indeed an asteroid impact structure and not some other, unrelated feature caused by, for example, ancient volcanism. […] Prof Sean Gulick, who co-led the recent project to drill into the Chicxulub Crater, said Nadir might have fallen to Earth on the same day. Or it might have struck the planet a million or two years either side of the Mexican cataclysm. Scientists will only know for sure when rocks from the west African crater are inspected in the lab. “A much smaller cousin, or sister, doesn’t necessarily add to what we know about the dinosaurs’ extinction, but it does add to our understanding of the astronomical event that was Chicxulub,” the University of Texas at Austin researcher told BBC News.

Saudi Arabia Sentences Woman To 34 Years In Prison For Tweeting

A Saudi woman has been sentenced to 34 years in prison for retweeting activists through her Twitter account and sharing posts that spoke in favor of the right of women to drive. The Verge reports: Salma al-Shehab was a PhD candidate at the University of Leeds in the UK and was detained in January 2021 after returning to Saudi Arabia for a vacation. Shehab was initially sentenced to six years for using social media to “disturb public order and destabilize the security and stability of the state,” based on having reshared tweets from Saudi activists living in exile who called for the release of political prisoners in the kingdom. The incident was reported in an editorial board piece from The Washington Post, which called it “yet another glimpse at the brutal underside of the Saudi dictatorship under its crown prince and de facto head of state, Mohammed bin Salman.”

The Post reports that prosecutors in the appeal to Shehab’s case argued for a more severe punishment under Saudi cybercrime and anti-terrorism laws, leading to a drastically increased sentence of 34 years, handed down on August 8th. The Freedom Initiative nonprofit, which advocates for the rights of prisoners detained in the Middle East, states that this is the longest known sentence for a women’s rights activist in Saudi Arabia.

Germany To Keep Last Three Nuclear-Power Plants Running In Policy U-Turn

Germany plans to keep its remaining nuclear power plants open for longer in a major U-turn as it scrambles to keep the lights on this winter with less Russian gas. The Telegraph reports: Officials have concluded the plants are needed due to gas shortages and they can be kept open without safety concerns, the Wall Street Journal reported. Germany pledged to phase out nuclear power after the Fukushima disaster in Japan in 2011, which hardened opposition to the technology. Berlin has been under pressure to change course since the invasion of Ukraine to limit the impact of the gas crisis on manufacturers and households. Germany has three plants left, operated by E.ON, EnBW and RWE, supplying about 6pc of the country’s electricity. They are currently due to close at the end of the year. Any extension has yet to be officially adopted and details remain under discussion, the Wall Street Journal added. It came as Norway warned it could not do more to help Germany avoid a gas crisis this winter as Russia restricts supplies.

Microsoft Employees Exposed Own Company’s Internal Logins

Multiple people who appear to be employees of Microsoft have exposed sensitive login credentials to the company’s own infrastructure on GitHub, potentially offering attackers a gateway into internal Microsoft systems, according to a cybersecurity research firm that found the exposed credentials. Motherboard reports: “We continue to see that accidental source code and credential leakages are part of the attack surface of a company, and it’s becoming more and more difficult to identify in a timely and accurate manner. This is a very challenging issue for most companies these days,” Mossab Hussein, chief security officer at cybersecurity firm spiderSilk which discovered the issue, told Motherboard in an online chat. Hussein provided Motherboard with seven examples in total of exposed Microsoft logins. All of these were credentials for Azure servers. Azure is Microsoft’s cloud computer service and is similar to Amazon Web Services. All of the exposed credentials were associated with an official Microsoft tenant ID. A tenant ID is a unique identifier linked to a particular set of Azure users. One of the GitHub users also listed Microsoft on their profile.

Three of the seven login credentials were still active when spiderSilk discovered them, with one seemingly uploaded just days ago at the time of writing. The other four sets of credentials were no longer active but still highlighted the risk of workers accidentally uploading keys for internal systems. Microsoft refused to elaborate on what systems the credentials were protecting when asked multiple times by Motherboard. But generally speaking, an attacker may have an opportunity to move onto other points of interest after gaining initial access to an internal system. One of the GitHub profiles with exposed and active credentials makes a reference to the Azure DevOps code repository. Highlighting the risk that such credentials may pose, in an apparently unrelated hack in March attackers gained access to an Azure DevOps account and then published a large amount of Microsoft source code, including for Bing and Microsoft’s Cortana assistant. “We’ve investigated and have taken action to secure these credentials,” said a Microsoft spokesperson in a statement. “While they were inadvertently made public, we haven’t seen any evidence that sensitive data was accessed or the credentials were used improperly. We’re continuing to investigate and will continue to take necessary steps to further prevent inadvertent sharing of credentials.”

Drought-Stricken States To Get Less From Colorado River

For the second year in a row, Arizona and Nevada will face cuts in the amount of water they can draw from the Colorado River as the West endures an extreme drought, federal officials announced Tuesday. The Associated Press reports: The cuts planned for next year will force states to make critical decisions about where to reduce consumption and whether to prioritize growing cities or agricultural areas. The cuts will also place state officials under renewed pressure to plan for a hotter, drier future and a growing population. Mexico will also face cuts. “We are taking steps to protect the 40 million people who depend on the Colorado River for their lives and livelihoods,” said Camille Touton, commissioner of the Bureau of Reclamation.

The river provides water across seven states and in Mexico and helps feed an agricultural industry valued at $15 billion a year. Cities and farms are anxiously awaiting official estimates of the river’s future water levels that will determine the extent and scope of cuts to their water supply. That’s not all. In addition to those already-agreed-to cuts, the Bureau of Reclamation said Tuesday that states had missed a deadline to propose at least 15% more cuts needed to keep water levels at the river’s storage reservoirs from dropping even more. For example, officials have predicted that water levels at Lake Mead, the nation’s largest reservoir, will plummet further. The lake is currently less than a quarter full. “The states collectively have not identified and adopted specific actions of sufficient magnitude that would stabilize the system,” Touton said.

New US Privacy Law May Give Telecoms Free Pass On $200 Million Fines

An anonymous reader quotes a report from Motherboard: The American Data Privacy and Protection Act (ADPPA), a new federal privacy bill that has actually a chance of becoming law, is designed to introduce new privacy protections for Americans. But it may also have the side effect of wiping out $200 million worth of fines proposed against some of the country’s biggest telecommunications companies as part of a major location-data selling scandal in which the firms sold customer data that ended up in the hands of bounty hunters and other parties. The issue centers around the ADPPA’s shift of enforcement for privacy related matters from the Federal Communications Commission (FCC), which proposed the fines, to the Federal Trade Commission (FTC). The news highlights the complex push and pulls when developing privacy legislation, and some of the pitfalls along the way.

The FCC proposed the $200 million fines in February 2020. The fines came after Motherboard revealed that the carriers sold phone location data to a complex supply chain of companies which then provided it to hundreds of bounty hunters and other third parties, including someone that allowed Motherboard to track a phone for just $300. The fines also came after The New York Times and the office of Sen. Ron Wyden found that the carriers sold location data in a similar method to a company called Securus, which allowed law enforcement officials to track the location of phones without a warrant. A former sheriff abused the tool to spy on judges and other officials. The offending telecoms — AT&T, T-Mobile, Sprint, Verizon — said they stopped the sale of location data at varying points in time in response to the investigations. The FCC then found that the carriers broke the law by selling such data.

FCC Press Secretary Paloma Perez told Motherboard in an emailed statement that “our real-time location information is some of the most sensitive data there is about us, and it deserves the highest level of privacy protection. That is why the FCC has proposed more than $200 million in fines against the nation’s largest wireless carriers for selling their customers’ location data. Through our continued oversight we have ensured that these carriers are no longer monetizing their consumers’ real-time location in this way, and we are continuing our investigation into these practices and expect to reach a conclusion very soon.” In July FCC Chairwoman Jessica Rosenworcel sent letters to a host of U.S. telecommunications, tech, and retail companies to ask about their use of location data.

WeWork’s Former CEO Has a New Startup, Reportedly Valued At More Than $1 Billion

Nearly three years after Adam Neumann stepped down as CEO of WeWork following a failed attempt to take the company public, he is said to once again be in charge of a billion-dollar real estate startup. CNN Business reports: Andreessen Horowitz, the prominent venture capital firm known for its early investments in Twitter and Airbnb, has pumped about $350 million into Neumann’s newest venture, called Flow, according to The New York Times, citing unnamed sources briefed on the deal. The investment valued the startup at more than $1 billion, according to the report. In a blog post Monday, Marc Andreessen, cofounder and general partner at the VC firm, announced the investment, without disclosing financial details. He also explained his thinking for backing Flow, a residential real estate company, and Neumann despite the founder’s high-profile fall from grace at WeWork.

“Adam is a visionary leader who revolutionized the second largest asset class in the world — commercial real estate — by bringing community and brand to an industry in which neither existed before,” Andreessen wrote in his post Monday. “Adam, and the story of WeWork, have been exhaustively chronicled, analyzed, and fictionalized — sometimes accurately. For all the energy put into covering the story, it’s often under appreciated that only one person has fundamentally redesigned the office experience and led a paradigm-changing global company in the process: Adam Neumann.” It’s not immediately clear how Flow seeks to revolutionize the residential housing industry. Flow currently has a bare bones website, with the slogan “Live life in flow” and two words stating it will launch in 2023.

Andreessen positioned the new company as a long-awaited solution to the nation’s “housing crisis.” He used a mix of jargon-filled terms — “community-driven, experience-centric service” — to explain how the new startup would “create a system where renters receive the benefits of owners.” “We think it is natural that for his first venture since WeWork, Adam returns to the theme of connecting people through transforming their physical spaces and building communities where people spend the most time: their homes,” Andreessen wrote. “Residential real estate — the world’s largest asset class — is ready for exactly this change.”

An Eye Implant Engineered From Proteins In Pigskin Restored Sight In 14 Blind People

According to a new study published in the journal Nature Biotechnology, researchers implanted corneas made from pig collagen to restore sight in 20 people who were blind or visually impaired. “Fourteen of the patients were blind before they received the implant, but two years after the procedure, they had regained some or all of their vision,” notes NBC News. “Three had perfect vision after the surgery.” From the report: The patients, in Iran and India, all suffered from keratoconus, a condition in which the protective outer layer of the eye progressively thins and bulges outward. “We were surprised with the degree of vision improvement,” said Neil Lagali, a professor of experimental ophthalmology at Linkoping University in Sweden who co-authored the study. Not all patients experienced the same degree of improvement, however. The 12 Iranian patients wound up with an average visual acuity of 20/58 with glasses; functional vision is defined as 20/40 or better with lenses. Nonetheless, Dr. Marian Macsai, a clinical professor of ophthalmology at the University of Chicago who wasn’t involved in the study, said the technology could be a game changer for those with keratoconus, which affects roughly 50 to 200 out of every 100,000 people. It might also have applications for other forms of corneal disease.

To create the implant, Lagali and his team dissolved pig tissue to form a purified collagen solution. That was used to engineer a hydrogel that mimics the human cornea. Surgeons then made an incision in a patient’s cornea for the hydrogel. “We insert our material into this pocket to thicken the cornea and to reshape it so that it can restore the cornea’s function,” Lagali said. Traditionally, human tissue is required for cornea transplants. But it’s in short supply, because people must volunteer to donate it after they die. So, Lagali said, his team was looking for a low-cost, widely available substitute. “Collagen from pigskin is a byproduct from the food industry,” he said. “This makes it broadly available and easier to procure.” After two years, the patients’ bodies hadn’t rejected the implants, and they didn’t have any inflammation or scarring.

But any experimental medical procedure comes with risk. In this case, Soiberman said, a foreign molecule like collagen could induce an immune reaction. The researchers prescribed patients an eight-week course of immunosuppressive eyedrops to lower the risk, which is less than the amount given to people who receive cornea transplants from human tissue. In those cases, patients take immunosuppressive medicine for more than a year, Lagali said. “There’s always a risk for rejection of the human donor tissue because it contains foreign cells,” he said. “Our implant does not contain any cells … so there’s a minimal risk of rejection.” The procedure itself was also quicker than traditional cornea transplants. The researchers said each operation took about 30 minutes, whereas transplants of human tissue can take a couple of hours. […] It’s not yet clear whether the surgery would work for patients who have other forms of corneal disease aside from keratoconus.
