“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”.

The singer known as Tomberlin says their first five years in the music industry may have been a net loss, according to MarketWatch. Selling “merch[andise]” like t-shirts “is what really is covering your costs and hopefully helping you make, like, an actual profit.”

And then…

After being told she would have to hand over more than 40% of the money she collected from selling T-shirts and other items, Tomberlin refused to sell her merchandise at the venue and publicly spoke about a practice she calls robbery — venues taking cuts from bands’ merchandise sales… Other musicians are also speaking out about the practice, and their complaints seem to be having an effect. Industry giant Live Nation Entertainment Inc. announced recently that it would stop collecting merch fees at nearly 80 of the smaller clubs it owns and operates and provide all bands that play at those venues with an additional $1,500 in gas cards and cash.

Musicians who spoke with MarketWatch remain unsatisfied, however. Because of the way the announcement is phrased, many think merch fees at Live Nation clubs are only being paused until the end of the year. The musicians said they also wonder about the roughly 250 other Live Nation concert facilities, as well as the hundreds of venues owned by other companies. A Live Nation spokesperson told MarketWatch the change is “open-ended.”

[…] As Tomberlin continues on her current tour, she wonders if she will be able to make a profitable career in music. Of all her ways of earning money, streaming services like Spotify and Apple Music provide “the least amount of money,” she said, and with tours not leaving her with any cash at the end, she feels that even modest ambitions are out of reach.

Musician Laura Jane Grace is even soliciting signers for an online petition demanding venues stop taking cuts of the musicians’ merchandise sales…

“To meet the world’s growing hunger for chips, a startup wants to upend the costly semiconductor fabrication plant with a nimbler, cheaper idea…” reports Fast Company, “an AI-enabled chip factory that can be assembled and expanded modularly with prefab pieces, like high-tech Lego bricks.”

In other words, they want to enable what is literally a fast company…
“We’re democratizing the ownership of semiconductor fabs,” says Matthew Putman, referring to chip fabrication plants. Putman is the founder and CEO of Nanotronics, a New York City-based industrial AI company that deploys advanced optical solutions for detecting defects in manufacturing procedures. Its new system, called Cubefabs, combines its modular inspection tools and other equipment with AI, allowing the proposed chip factories to monitor themselves and adapt accordingly — part of what Putman calls an “autonomous factory.” The bulk of the facility can be preassembled, flat-packed and put in shipping containers so that the facilities can be built “in 80% of the world,” says Putman.

Eventually, the company envisions hundreds of the flower-shaped fabs around the world, starting with a prototype in New York or Kuwait that it hopes to start building by the end of the year… Nanotronics says a single Cubefab installation could start at one acre with a single fab, and grow to a four-fab, six-acre footprint. Each fab could be built in under a year, the company says, with a four-fab installation estimated to cost under $100 million. Nanotronics declined to disclose how much it has raised for the project, but Putman says the company has previously raised $170 million from investors, including Peter Thiel and Jann Tallin, the Skype cofounder…

A single automated Cubefab will need only about 30 people to operate, “and they don’t have to be semiconductor experts,” says Putman. “AI takes away that need for that specialization that you would normally need in a fab.” […] Putman also hopes automation will help further reduce the environmental impact of an industry that’s notoriously resource-intensive and produces thousands of tons of waste a year, much of it hazardous. “Because you have the AI fixing the material and the device before it’s manufactured, you have less waste of the final material,” he says.

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.

Yesterday America’s Federal Trade Commission said it remained focused on its appeal opposing Microsoft’s deal to buy Activision, reports Reuters.

Reuters notes that Microsoft and Activision closed their transaction Friday “after winning approval from Britain on condition that they sell the streaming rights to Activision’s games to Ubisoft Entertainment.” But the U.S. Federal Trade Commission “has also fought the deal, and has an argument scheduled before an appeals court on December 6. The agency said on Friday that it remained focused on that appeal.” An FTC spokesperson had this comment for Reuters.
“The FTC continues to believe this deal is a threat to competition.”

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.

Long-time Slashdot reader SonicSpike shared the Washington Post’s speculation about the possibility of a gigantic solar storm leaving millions without phone or internet access, and requiring months or years of rebuilding:
The odds are low that in any given year a storm big enough to cause effects this widespread will happen. And the severity of those impacts will depend on many factors, including the state of our planet’s magnetic field on that day. But it’s a near certainty that some form of this catastrophe will happen someday, says Ian Cohen, a chief scientist who studies heliophysics at the Johns Hopkins Applied Physics Laboratory.

Long-time Slashdot reader davidwr remains skeptical. “I’ve only heard of two major events in the last 1300 years, one estimated to be between A. D. 744 and A. D. 993, and the other being the Carrington Event in 1859.

But efforts are being made to improve our readiness, reports the Washington Post:
To get ahead of this threat, a loose federation of U.S. and international government agencies, and hundreds of scientists affiliated with those bodies, have begun working on how to make predictions about what our Sun might do. And a small but growing cadre of scientists argue that artificial intelligence will be an essential component of efforts to give us advance notice of such a storm…

At present, no warning system is capable of giving us more than a few hours’ notice of a devastating solar storm. If it’s moving fast enough, it could be as little as 15 minutes. The most useful sentinel — a sun-orbiting satellite launched by the U.S. in 2015 — is much closer to Earth than the sun, so that by the time a fast-moving storm crosses its path, an hour or less is all the warning we get. The European Space Agency has proposed a system to help give earlier warning by putting a satellite dubbed Vigil into orbit around the Sun, positioned roughly the same distance from the Earth as the Earth is from the Sun. It could potentially give us up to five hours of warning about an incoming solar storm-enough time to do the main thing that can help preserve electronics: Switch them all off.
But what if there were a way to predict this better, by analyzing the data we’ve got? That’s the idea behind a new, AI-powered model recently unveiled by scientists at the Frontier Development Lab — a public-private partnership that includes NASA, the U.S. Geological Survey, and the U.S. Department of Energy. The model uses deep learning, a type of AI, to examine the flow of the solar wind, the usually calm stream of particles that flow outward from our sun and through the solar system to well beyond the orbit of Pluto. Using observations of that solar wind, the model can predict the “geomagnetic disturbance” an incoming solar storm observed by sun-orbiting satellites would cause at any given point on Earth, the researchers involved say. This model can predict just how big the flux of the Earth’s magnetic field will be when the solar storm arrives, and thus how big the induced currents in power lines and undersea internet cables will be…

Already, the first primitive ancestor of future AI-based solar-weather alert systems is live. The DstLive system, which debuted on the web in December 2022, uses machine learning to take data about the state of Earth’s magnetic field and the solar wind and translate both into a single measure for the entire planet, known as DST. Think of it as the Richter scale, but for solar storms. This number is intended to give us an idea of how intense a storm’s impact will be on earth, an hour to six hours in advance.

Unfortunately, we may not know how useful such systems are until we live through a major solar storm.

An anonymous reader quotes a report from the BBC: A thief who stole more than $470 million in cryptocurrency when FTX crashed is trying to cash it out while the exchange’s founder is on trial. Sam Bankman-Fried’s high-profile court case began last week. The former crypto mogul denies fraud. After lying dormant for nine months, experts say $20 million of the stolen stash is being laundered into traditional money every day. New analysis shows how the mystery thief is trying to hide their tracks. […] On the day FTX collapsed, hundreds of millions of dollars of cryptocurrency controlled by the exchange were stolen by an unidentified thief that is believed to still have control of the funds. No one knows how the thief — or thieves — was able to get digital keys to FTX crypto wallets, but it is thought it was either an insider or a hacker who was able to steal the information. The criminal moved 9,500 Ethereum coins, then worth $15.5 million, from a wallet belonging to FTX, to a new wallet. Over the next few hours, hundreds of other cryptoassets were taken from the company’s wallets, in transactions eventually totaling $477 million.

According to researchers from Elliptic, a cryptocurrency investigation firm, the thief lost more than $100 million in the weeks following the hack as some was frozen or lost in processing fees as they frantically moved the funds around to evade capture. But by December around $70 million was successfully sent to a cryptocurrency mixer — a criminal service used to launder Bitcoin, making it difficult to trace. […] Although mixers make it difficult to trace Bitcoin, Elliptic was able to follow a small amount of the funds — $4 million — that was sent to an exchange. The rest of the stolen FTX stash — around $230 million — remained untouched until 30 September — the weekend before Mr Bankman-Fried’s trial began. Nearly every day since then chunks worth millions have been sent to a mixer for laundering and then presumably cashing out. Elliptic has been able to trace $54 million of Bitcoin being sent to the Sinbad mixer after which the trail has gone cold for now. “Crypto launderers have been known to wait for years to move and cash out assets once public attention has dissipated, but in this case they have begun to move just as the world’s attention is once again directed towards FTX and the events of November 2022,” said Tom Robinson, Elliptic’s co-founder.
