AlmaLinux Stays Red Hat Enterprise Linux Compatible Without Red Hat Code (zdnet.com) 34

AlmaLinux is creating a Red Hat Enterprise Linux (RHEL) without any Red Hat code. Instead, AlmaLinux OS will aim to be Application Binary Interface (ABI) compatible and use the CentOS Stream source code that Red Hat continues to offer. Additional code is pulled from Red Hat Universal Base Images, and upstream Linux code. Benny Vasquez, chairperson of the AlmaLinux OF Foundation, explained how all this works at the open-source community convention All Things Open. ZDNet's Steven Vaughan-Nichols reports: The hardest part is Red Hat's Linux kernel updates because, added Vasquez, "you can't get those kernel updates without violating Red Hat's licensing agreements." Therefore, she continued, "What we do is we pull the security patches from various other sources, and, if nothing else, we can find them when Oracle releases them." Vasquez did note one blessing from this change in production: "AlmaLinux, no longer bound to Red Hat's releases, has been able to release upstream security fixes faster than Red Hat. "For example, the AMD microcode exploits were patched before Red Hat because they took a little bit of extra time to get out the door. We then pulled in, tested, and out the door about a week ahead of them." The overall goal remains to maintain RHEL compatibility. "Any breaking changes between RHEL and AlmaLinux, any application that stops working, is a bug and must be fixed."

That's not to say AlmaLinux will be simply an excellent RHEL clone going forward. It plans to add features of its own. For instance, Red Hat users who want programs not bundled in RHEL often turn to Extra Packages for Enterprise Linux (EPEL). These typically are programs included in Fedora Linux. Besides supporting EPEL software, AlmaLinux has its own extra software package -- called Synergy -- which holds programs that the AlmaLinux community wants but are not available in either EPEL or RHEL. If one such program is subsequently added to EPEL or RHEL, AlmaLinux drops it from Synergy to prevent confusion and duplication of effort.

This has not been an easy road for AlmaLinux. Even a 1% code difference is a lot to write and maintain. For example, when AlmaLinux tried to patch CentOS Stream code to fix a problem, Red Hat was downright grumpy about AlmaLinux's attempt to fix a security hole. Vasquez acknowledged it was tough sledding at first, but noted: "The good news is that they have been improving the process, and things will look a little bit smoother." AlmaLinux, she noted, is also not so much worried as aware that Red Hat may throw a monkey wrench into their efforts. Vasquez added: "Internally, we're working on stopgap things we'd need to do to anticipate Red Hat changing everything terribly." She doesn't think Red Hat will do it, but "we want to be as prepared as possible."

Tesla Announces Cybertruck Deliveries In November, Claims 125K Production Capacity (electrek.co) 127

An anonymous reader quotes a report from Electrek: Today, Tesla released (PDF) its Q3 2023 financial results and as expected, there was an update about Cybertruck in there. In the quarterly presentation, Tesla mentioned that "pilot production" of the Cybertruck has begun: "At Gigafactory Texas, we began pilot production of the Cybertruck, which remains on track for initial deliveries this year." While that doesn't include any new information, in the photo section of the presentation, Tesla added a comment confirming that "deliveries will begin in November 2023."

The previous official comment from CEO Elon Musk was that Tesla was aiming for the end of Q3, which ended last month. Interestingly, Tesla also updated its "installed annual vehicle capacity" and added capacity for the Cybertruck for the first time. Surprisingly, Tesla already claims a capacity of "over 125,000 Cybertrucks" at Gigafactory Texas.
In a company post on X, Tesla specifies that its first Cybertruck deliveries are scheduled for November 30th at Giga Texas.

These are the highlights of Tesla's Q3 shareholder update, as mentioned in the company's X post: "Cybertruck production remains on track for later this year, with first deliveries scheduled for November 30th at Giga Texas.

Production of our higher density 4680 cell is progressing as planned & we continue building capacity for cathode production & lithium refining in the US.

In Europe, Model Y remains the best-selling vehicle of any kind (based on latest available data as of August) Thank you to our European owners!

We have more than doubled the size of our AI training compute, accommodating for both our growing data set & Optimus, which is currently being trained for simple tasks through AI rather than hardcoded software, while its hardware continues to improve.

All Hertz rentals in the US & Canada now allow Tesla app access, enabling renters to use keyless lock/unlock via phone key, remotely precondition the cabin & more.

In addition, we redesigned the in-app service experience for owners, making scheduling & tracking service appointments & loaner access much simpler."

Amazon Plans To Deploy Delivery Drones In the UK and Italy Next Year (theverge.com) 16

Amazon announced today that it plans to expand its Prime Air drone delivery program to Italy and United Kingdom, as well as one more yet-to-be-named U.S. city. "The new Prime Air locations will be announced in the coming months, with an anticipated launch date of late 2024," reports The Verge. From the report: Another step by Amazon today suggests it's ready to make drones a more serious part of its actual delivery network. The company said it plans to add Prime Air delivery to its existing fulfillment network -- specifically by adding delivery drones to some of its same-delivery sites. Prime Air drones currently only operate out of the two standalone sites in Texas and California, so expanding drones to other sites means a wider delivery range and closer integration with Amazon's delivery network.

Amazon also gave us a sneak peek of its new Prime Air delivery drone that it claims flies twice as far as its current model. Even more critically, the drones will be able to operate in light rain and what Amazon calls more "diverse weather." The company released photos of the MK30 drone today, which it said will replace its existing delivery drones by late 2024.

The MK30 is also smaller and quieter than the existing Prime Air model, Amazon claims. The new drone can deliver objects of up to five pounds, with a typical delivery time of "one hour or less." The new drone includes a "sense and avoid" feature that can help it avoid pets, people, and property. The new design will hopefully result in smoother flights.
"Not only will this help boost the economy, offering consumers even more choice while helping keep the environment clean with zero emission technology, but it will also build our understanding how to best use the new technology safely and securely," said UK's Aviation Minister Baroness Vere in a statement in Amazon's announcement.

Tech Leaders Say AI Will Change What It Means To Have a Job (wsj.com) 147

AI will likely lead to seismic changes to the workforce, eliminating many professions and requiring a societal rethink of how people spend their time, prominent tech leaders said Tuesday. From a report: Speaking at The Wall Street Journal's Tech Live conference on Tuesday, OpenAI CEO Sam Altman said that the changes could hit some people in the economy more seriously than others, even if society as a whole improves. This will likely be a hard sell for the most affected people, he said. "We are really going to have to do something about this transition," said Altman, who added that society will have to confront the speed at which the change happens. "People need to have agency, the ability to influence. We need to jointly be architects of the future." Artificial intelligence is expected to transform the global economy by driving gains in both productivity and growth. But economists and tech entrepreneurs are divided on how quickly this shift could -- and should -- happen.

Earlier Tuesday, Vinod Khosla, a prominent venture capitalist whose firm was one of OpenAI's earliest backers, laid out a stark timeline for AI's transformation of work. Within 10 years AI will be able to "do 80% of 80% of all jobs that we know of today," said Khosla, a tech investor and entrepreneur for more than 40 years. He pointed to many types of physicians and accountants as examples of professions that AI could largely supplant because these systems can more easily access a broad array of knowledge. Khosla likened the extent of the workforce changes to the disappearance of agricultural jobs in the U.S. in the 20th Century -- a transition that took place over generations, not years.

Joseon Becomes First-ever Globally Recognized Cyber Nation-state 115

An anonymous reader quotes a report from U.Today:
The country was reimagined by Joseon King Andrew Lee as a digital nation without territory or borders. In this status, it was recognized by Antigua and Barbuda: the two countries inked a treaty that supports education, economic investment and other developmental initiatives and provides the basis for long-standing friendly relations.

Speaking to U.Today, representatives of the country stressed its unique legal design and state management model:

"Joseon is a crypto safe haven in this world where you can legally engage in crypto without any risk of any kind because sovereignty is the absolute authority in this world and another sovereignty doesn't have authority over another sovereignty"

Per their official statement, cryptocurrencies represent legal tender in Joseon and can be used for investments, daily payments and cross-border transactions.

Another report from Bitcoinist details several companies launching in Joseon, including First Day Out Collective which represents a song from Rundown Spaz and Kanye West:
Let's talk about the banger that's making this all come alive: "First Day Out,: a fire track by Rundown Spaz featuring none other than Kanye West, now owned by a DAO and legally recognized corporation in the progressive cybernation of Joseon, which itself is a legally recognized nation-state.

GM Delays EV Truck Production At Michigan Plant By Another Year (reuters.com) 114

General Motors said it will delay production of electric pickups trucks at its plant in Michigan by another year as the No. 1 U.S. automaker grapples with flattening demand for electric vehicles. Reuters reports: The move is the latest sign that electric vehicle production and demand may not be as strong as forecast. GM had been set to begin production of the electric Chevrolet Silverado and GMC Sierra in late 2024 at the suburban Detroit plant. The company said the plan now is to start it in late 2025.

GM said the change was being made "to better manage capital investment while aligning with evolving EV demand" but said the move does not impact its battery plant plans. GM said in July battery production at the Ultium joint venture plant Ohio has been hampered because "our automation equipment supplier is struggling with delivery issues."

The automaker in July reiterated a previous target of building 400,000 EVs from 2022 through the first half of 2024, and projected EV revenue of $50 billion in 2025. GM has said it is targeting production of roughly 100,000 EVs in the second half of 2023. Reuters reported in July that the U.S. electric vehicle market is growing, but not quickly enough to prevent unsold EVs from stacking up at some automakers' dealerships.

Mazda's DMCA Takedown Kills a Hobbyist's Smart Car API Tool (arstechnica.com) 28

Long-time Slashdot reader couchslug shares a report from Ars Technica, writing: "A new attack on the right to do with one's property as the owner sees fit. First step, threaten without providing evidence." From the report: Before last week, owners of certain Mazda vehicles who also had a Home Assistant setup could create some handy connections for their car. One CX60 driver had a charger that would only power on when it confirmed his car was plugged in and would alert him if he left the trunk open. Another used Home Assistant to control their charger based on the dynamic prices of an Agile Octopus energy plan. Yet another had really thought it through, using Home Assistant to check the gas before their morning commute, alert them if their windows were down before rain was forecast, and remotely unlock and start the car in cold conditions. The possibilities were vast, and purportedly beyond what Mazda's official app offered.

Mazda, however, had issues with the project, which was largely the free-time work of one software developer, Brandon Rothweiler. In a Digital Millennium Copyright Act (DMCA) notice sent to GitHub, Mazda (or an authorized agent) alleges that Rothweiler's integration: contains code that "is violating [Mazda's] copyright ownership"; used "certain Mazda information, including proprietary API information," to "create code and information"; and contained code that "provides functionality same as what is currently" in Mazda's apps posted to the Apple App Store and Google Play Store for Android.

One day later, Rothweiler made a pull request to the Home Assistant core project: "I'm removing the Mazda integration due to a legal notice sent to me by Mazda." The Home Assistant project pushed an update to remove the integration, posted about the removal, and noted that they were "disappointed that Mazda has decided to take this position" and that "Mazda's first recourse was not to reach out to us and the maintainer but to send a cease and desist letter instead."
One of the many commenters confused by Mazda's code claims said they couldn't find any of the copyrighted code the company referenced. Additionally, Ars Technica suggests the project "could be considered a fair use exception to the DMCA, as explained by the Electronic Frontier Foundation."

"When Mazda contacted me, my options were to either comply or open myself up to potential legal risk," said Rothweiler. "Even if I believe that what I'm doing is morally correct and legally protected, legal processes still have a financial cost. I can't afford to take on that financial risk for something that I do in my spare time to help others."

Reddit is Killing Blockchain-Based Community Points (techcrunch.com) 10

Reddit is winding down Community Points -- the blockchain-based "internet points" program designed to reward creators and developers -- in favor of prioritizing rewards programs that are less difficult to scale. From a report: "Though we saw some future opportunities for Community Points, the resourcing needed was unfortunately too high to justify," Reddit's director of consumer and product communications Tim Rathschmidt told TechCrunch. "The regulatory environment has since added to that effort. Though the moderators and communities that supported Community Points have been incredible partners -- as it's evolved, the product is no longer set up to scale."

Community Points, which will be phased out by early November, were promoted as a chance for Redditors to "own" a piece of their community. First launched in 2020, Community Points were awarded to users who positively engaged in select subreddits in order to incentivize better content and conversation. The points were essentially interchangeable Ethereum tokens stored in Reddit's Vault, which operated as a cryptocurrency wallet.

Windows 11 is Active on Almost Half a Billion Devices (windowscentral.com) 63

Windows Central: According to my sources who are familiar with the matter, Windows 11 is now in use on over 400 million monthly active devices. Internal Microsoft data seen by Windows Central reveals that Windows 11's active device usage just recently surpassed 400 million and is steadily climbing to reach half a billion by early 2024. As noted in our Windows 11 review, the OS has been on the market since October 2021, meaning it's taken Microsoft around two years to reach 400 million monthly active devices with Windows 11. This is a significantly slower rate than Windows 10, which reached the same number in just over a year (and eventually 1 billion users by early 2020). Still, factoring in both platforms' very different launch parameters is essential.

Google Asks Congress To Not Ban Teens From Social Media (theverge.com) 118

An anonymous reader quotes a report from The Verge: Google responded to congressional child online safety proposals with its own counteroffer for the first time Monday, urging lawmakers to drop problematic protections like age-verification tech. In a blog post, Google released its "Legislative Framework to Protect Children and Teens Online" (PDF). The framework comes as more lawmakers, like Sen. Elizabeth Warren (D-MA), are lining up behind the Kids Online Safety Act, a controversial bill intended to protect kids from dangerous content online.

In the framework, Google rejects state and federal attempts at requiring platforms to verify the age of users, like forcing users to upload copies of their government IDs to access an online service. Some states have recently gone as far as passing laws requiring platforms to obtain parental consent before anyone under 18 is allowed to use their services. Google dismisses these consent laws, arguing that they bar vulnerable teens from accessing helpful information.
"Good legislative models -- like those based on age-appropriate design principles -- can help hold companies responsible for promoting safety and privacy, while enabling access to richer experiences for children and teens," Kent Walker, Google's president of global affairs, said in the blog post.

'World's First Off-Road Solar SUV' Just Drove Across Morocco (cnn.com) 82

An anonymous reader quotes a report from CNN: Zero-emission cars are soaring in popularity but running an electric vehicle is next to impossible in places with limited charging infrastructure. Stella Terra could change that. The khaki-green SUV uses solar panels on its sloping roof to charge its electric battery, meaning it can drive long distances powered entirely by the sun. Built by a team of students at Eindhoven University of Technology (TUE), "the world's first off-road solar-powered vehicle" could help connect remote areas "where roads are less developed and energy grids are not as reliable," and assist with emergency aid and deliveries, says Thieme Bosman, events manager for the team.

The team tested the vehicle in Morocco earlier this month, driving more than 1,000 kilometers (621 miles) between the country's northern coast and the Sahara Desert in the south. "Morocco has a huge variety of landscapes and different surfaces in quite a short distance," says Bosman, adding that the car was tested "on every type of surface that a car like this could encounter." The road-legal car has a top speed of 145 kilometers (90 miles) per hour. On a sunny day, its battery range is around 710 kilometers (441 miles) on roads, and around 550 kilometers (342 miles) off-road, depending on the surface. In cloudy conditions, the team estimates the range could be 50 kilometers less. Bosman noted that the vehicle had proved to be one-third more efficient than expected on the trip, and that its lightweight design made it less liable to get stuck on rugged terrain, and put less stress on its suspension.

"Where the SUV market currently innovates on the previous models, we really start from scratch and design everything ourselves," says Bosman. Minimizing the vehicle's weight was essential, and the team of 22 students focused on making every element ultra-efficient. At just 2,645 pounds (1,200 kilograms), Stella Terra weighs around 25% less than the average mid-sized SUV. The aerodynamic design also reduces drag and uses "lightweight and robust" composite materials to cut weight, says Bob van Ginkel, technical manager for Stella Terra. "(One of) the benefits of the solar panels on top is that we can have a much smaller battery because we are charging while driving," van Ginkel adds.
Bosman and his peers hope their concept SUV could be mass produced in the near future. "We aim to also inspire not only everyday people, but also the automotive industry, the Ford and Chryslers of the world, to think again about their designs and to innovate faster than they currently do," says Bosman.

"It's up to the market now, who have the resources and the power to make this change and the switch to more sustainable vehicles."

Comcast Resists Call To Stop Its Misleading '10G Network' Claims (arstechnica.com) 39

Jon Brodkin reports via Ars Technica: An advertising industry group urged Comcast to stop its "10G" ads or modify them to state that 10G is an "aspirational" technology rather than something the company actually provides on its cable network today. The National Advertising Division (NAD), part of the advertising industry's self-regulatory system run by BBB National Programs, ruled against Comcast after a challenge lodged by T-Mobile. In its decision announced Thursday, the NAD recommended that Comcast "discontinue its '10G' claims" or "modify its advertising to (a) make clear that it is implementing improvements that will enable it to achieve '10G' and that it is aspirational or (b) use '10G' in a manner that is not false or misleading, consistent with this decision."

Comcast plans to appeal the decision, so it won't make any changes to marketing immediately. If Comcast loses the appeal and agrees to change its practices, it would affect more than just a few ads because Comcast now calls its entire broadband network "10G." "In February 2023, Comcast rebranded its fixed Internet network as 'Xfinity 10G Network' to signify technological upgrades to its network that are continuing to be implemented," the NAD said. Comcast's website claims that the "Xfinity 10G Network is already here! You'll see continual increases in network speed and reliability. No action is required on your part to join the Xfinity 10G Network." It also claims that 10G is "complementary" to the 5G mobile network.

Colorado Supreme Court Approves Use of Google Search Data in Murder Case (bloomberg.com) 56

The Colorado Supreme Court ruled today that evidence gleaned from a warrant for Google's search data could be used in the prosecution of a teen who was charged with murder for a fire that killed five people in the Denver area. From a report: As police scrambled to solve the source of the 2020 blaze, they asked Alphabet's Google to provide information about people who searched for the address of the house that went up in flames, using a controversial technique known as a keyword search warrant. After some initial objections, Google provided data that enabled detectives to zero in on five accounts, leading to the arrest of three suspects in the case.

Lawyers for one of the suspects, Gavin Seymour, who was found to have Googled the home's address 14 times in the days before the fire, argued that the keyword warrant constituted an illegal search and that any evidence from it should be suppressed. His motion is the first known challenge to the constitutionality of keyword search warrants. The case is ongoing. In its 74-page decision, the court found that law enforcement had acted in good faith when it obtained the warrant for the teen's search history. Still, it stressed that the findings were specific to the facts of the case, and it refrained from weighing in about the use of Google's search data more broadly.

Google's AI-Powered 'Project Green Light' Speeds Traffic, Reduces Fuel Consumption and Carbon Emissions (engadget.com) 93

Google's "Project Green Light" uses machine learning on Maps data to optimize the length of green lights, reports Engadget, "reducing idle times as well as the amount of braking and accelerating vehicles have to do there." When the program was first announced in 2021, it had only been pilot tested in four intersections in Israel in partnership with the Israel National Roads Company but Google had reportedly observed a "10 to 20% reduction in fuel and intersection delay time" during those tests. The pilot program has grown since then, spreading to a dozen partner cities around the world, including Rio de Janeiro, Brazil; Manchester, England and Jakarta, Indonesia. "Today we're happy to share that... we plan to scale to more cities in 2024," Yael Maguire, Google VP of Geo Sustainability, told reporters during a pre-brief event last week. "Early numbers indicate a potential for us to see a 30% reduction in stops...."

Maguire also noted that the Manchester test reportedly saw improvements to emission levels and air quality rise by as much as 18%. The company also touted the efficacy of its Maps routing in reducing emissions, with Maguire pointing out that it had "helped prevent more than 2.4 million metric tons of carbon emissions — the equivalent of taking about 500,000 fuel-based cars off the road for an entire year."

To 'Evolve' Windows Authentication, Microsoft Wants to Eventually Disable NTLM in Windows 11 (neowin.net) 68

An anonymous reader shared this report from Neowin: The various versions of Windows have used Kerberos as its main authentication protocol for over 20 years. However, in certain circumstances, the OS has to use another method, NTLM (NT LAN Manager). Today, Microsoft announced that it is expanding the use of Kerberos, with the plan to eventually ditch the use of NTLM altogether.

In a blog post, Microsoft stated that NTLM continues to be used by some businesses and organizations for Windows authentication because it "doesn't require local network connection to a Domain Controller." It also is "the only protocol supported when using local accounts" and it "works when you don't know who the target server is." Microsoft states:

These benefits have led to some applications and services hardcoding the use of NTLM instead of trying to use other, more modern authentication protocols like Kerberos. Kerberos provides better security guarantees and is more extensible than NTLM, which is why it is now a preferred default protocol in Windows. The problem is that while businesses can turn off NTLM for authentication, those hardwired apps and services could experience issues. That's why Microsoft has added two new authentication features to Kerberos.

Microsoft's blog post calls it "the evolution of Windows authentication," arguing that "As Windows evolves to meet the needs of our ever-changing world, the way we protect users must also evolve to address modern security challenges..." So, "our team is building new features for Windows 11."
  • Initial and Pass Through Authentication Using Kerberos, or IAKerb, "a public extension to the industry standard Kerberos protocol that allows a client without line-of-sight to a Domain Controller to authenticate through a server that does have line-of-sight."
  • A local Key Distribution Center (KDC) for Kerberos, "built on top of the local machine's Security Account Manager so remote authentication of local user accounts can be done using Kerberos."
  • "We are also fixing hard-coded instances of NTLM built into existing Windows components... shifting these components to use the Negotiate protocol so that Kerberos can be used instead of NTLM... NTLM will continue to be available as a fallback to maintain existing compatibility."
  • "We are also introducing improved NTLM auditing and management functionality to give your organization more insight into your NTLM usage and better control for removing it."

"Reducing the use of NTLM will ultimately culminate in it being disabled in Windows 11. We are taking a data-driven approach and monitoring reductions in NTLM usage to determine when it will be safe to disable."

How a Series of Air Traffic Control Lapses Nearly Killed 131 People (deccanherald.com) 58

Due to an air traffic control mistake in February, a FedEx cargo plane flew within 100 feet of a Southwest Airlines flight in February. The New York Times reports that the flight's 128 passengers "were unaware that they had nearly died." In a year filled with close calls involving US airlines, this was the one that most unnerved federal aviation officials: A disaster had barely been averted, and multiple layers of the vaunted US air-safety system had failed... But the errors by the controller — who has continued to direct some plane traffic in Austin, Texas — were far from the whole story, according to 10 current and former controllers there, as well as internal Federal Aviation Administration documents reviewed by the Times. Austin-Bergstrom, like the vast majority of US airports, lacks technology that allows controllers to track planes on the ground and that warns of imminent collisions. The result is that on foggy days, controllers can't always see what is happening on runways and taxiways. Some have even resorted to using a public flight-tracking website in lieu of radar.

In addition, for years Austin has had a shortage of experienced controllers, even as traffic at the airport has surged to record levels. Nearly three-quarters of shifts have been understaffed. Managers and rank-and-file controllers have repeatedly warned that staffing levels pose a public danger. The controller on that February morning was working an overtime shift. In June, Stephen B. Martin, then Austin's top manager, and a local union representative wrote a memo pleading for more controllers. "Drastic steps are needed to allow the facility to adequately staff for existing traffic," they wrote to FAA and union officials.

Austin is a microcosm of a systemic crisis. The safety net that underpins air travel in America is fraying, exposing passengers to potential tragedies like the episode in February.

And yet the chair of America's National Transportation Safety Board calls the February incident "just one of seven serious close calls and near misses involving commercial airlines that we have initiated investigations on this year."

Australian Student Invents Affordable Electric Car Conversion Kit. (dezeen.com) 88

"Australian design student Alexander Burton has developed a prototype kit for cheaply converting petrol or diesel cars to hybrid electric," reports Dezeen magazine, "winning the country's national James Dyson Award in the process." Titled REVR (Rapid Electric Vehicle Retrofits), the kit is meant to provide a cheaper, easier alternative to current electric car conversion services, which Burton estimates cost AU$50,000 (£26,400) on average and so are often reserved for valuable, classic vehicles.

Usually, the process would involve removing the internal combustion engine and all its associated hardware, like the gearbox and hydraulic brakes, to replace them with batteries and electric motors. With REVR, those components are left untouched. Instead, a flat, compact, power-dense axial flux motor would be mounted between the car's rear wheels and disc brakes, and a battery and controller system placed in the spare wheel well or boot. Some additional off-the-shelf systems — brake and steering boosters, as well as e-heating and air conditioning — would also be added under the hood. By taking this approach, Burton believes he'll be able to offer the product for around AU$5,000 (£2,640) and make it compatible with virtually any car...

With REVR, people should be able to get several more years of life out of their existing cars. The kit would transform the vehicle into a hybrid rather than a fully electric vehicle, with a small battery giving the car 100 kilometres of electric range before the driver has to switch to the internal combustion engine... Borrowing a trick from existing hybrid vehicles, the kit uses a sensor to detect the position of the accelerator pedal to control both acceleration and braking. That means no changes have to be made to the car's hydraulic braking system, which Burton says "you don't want to have to interrupt".

Chinese Scientists Claim Record-Smashing Quantum Computing Breakthrough (scmp.com) 44

From the South China Morning Post: Scientists in China say their latest quantum computer has solved an ultra-complicated mathematical problem within a millionth of a second — more than 20 billion years quicker than the world's fastest supercomputer could achieve the same task. The JiuZhang 3 prototype also smashed the record set by its predecessor in the series, with a one million-fold increase in calculation speed, according to a paper published on Tuesday by the peer-reviewed journal Physical Review Letters...

The series uses photons — tiny particles that travel at the speed of light — as the physical medium for calculations, with each one carrying a qubit, the basic unit of quantum information... The fastest classical supercomputer Frontier — developed in the US and named the world's most powerful in mid-2022 — would take over 20 billion years to complete the same task, the researchers said.

The article claims they've increased the number of photons from 76 to 113 in the first two versions, improving to 255 in the latest iteration.

Third-party Reddit App Narwhal Hopes To Survive Reddit's App Purge With Subscriptions (techcrunch.com) 20

An anonymous reader shared this report from TechCrunch: After a nasty battle between the developers of third-party apps and Reddit management, ultimately resulting in a site-wide protest, many app makers were put out of business due to Reddit's price increases related to the usage of its API. Though the changes meant the loss of popular apps like Apollo, RIF (Reddit is Fun), ReddPlanent, Sync and BaconReader, one app, Narwhal, is attempting to make a comeback. The company announced this week that it will implement a subscription-based version of its app at $3.99 per month, promising an ad-free and privacy-focused experience.

The new app will also include a Tip Jar to solicit donations to help keep the app afloat beyond the subscription fees and fund additional development work. Though not available at launch, the app's developer Rick Harrison (u/det0ur on Reddit and CTO at Meadow by day) says he's considering adding a small fee, perhaps $1 per month, to allow users to also check their notifications and messages... Notes Narwhal's developer, Reddit's fee will be "tens of thousands if not hundreds of thousands a month depending on how many people subscribe." To work, the app will need a critical mass of subscribers to cover its costs, but Harrison says he's fairly confident the model will work.

"Also, with a simpler plan like this, I can offer a subscription on a Narwhal website for 30% less (no Apple cut)," Harrison wrote...

Narwhal isn't the only Reddit client to attempt to remain in business despite Reddit's API pricing changes. Another, Relay, announced a multi-tier subscription plan where users have to choose one of six price points, each that caps them at a certain number of API calls.
