I've had some trouble setting up a pie-hole. It's an imperfect system and something of a constant struggle between advertisers and ad-blockers.

If you've escaped every digital ad over the last 25 years, congrats. I'm reasonably tech savy, use adblockers where I can, and haven't been remotely this fortunate.

Nah, his complaint was lack of torque.

Maybe just had torque confused with horsepower? That's been the historical trade-off between gas and electric. Sure, its very easy to get an electric motor to jump into action. But it is comparatively difficult to generate the same amount of power with equivalent fuel density.

A gallon of refined gasoline packs insane energy.

Much of which is lost to heat when combusted, which is the historical hang-up.

Not that batteries don't have their own heating problems. But the benefit of batteries is that they're an engineering problem we can solve with miniaturization, which we've become incredibly good at. We're at a soft ceiling in terms of engine chemistry. Petroleum is about as refined as we're going to get it. Combustion's math is what it is. Improvements to the efficiency of modern engines have stalled out as an automotive tool, even to the point that a gas engine powering an electric capacitor in a hybrid yields performance improvements over the gas engine just spinning the wheels directly.

What could he have possibly been trying to say?

I mean, the general appeal of ICE engines is the fuel, not the engine. Gasoline is generally more energy dense than lithium.

Generally speaking, I don't check the age/gross karma on an account unless I'm suspicious. And by then... plenty of older accounts with lots of karma are HailCorporate to the gills. Nevermind the mods.

I just can't take anything on that site seriously

"At least" is doing some heavy lifting

start composting

In my non-existent backyard?

The Toxic Lie of American Recycling: How Plastic Shipments Are Destroying Asia

For decades, the U.S., along with other countries, have been sending much of its plastic “recycling” to Asian countries to process, as running a well-functioning recycling program is more labor intensive and expensive than Americans would care to operate.[1] This relationship began as a way for Asian countries to turn a profit by importing the U.S.’ recycling to manufacture into new plastics.[2] But when the imports became excessive as Americans used more and more plastic, some countries chose to ban them, leaving an even heavier burden on places still accepting the imports.[3] Malaysia is one such country feeling this strain.[4]

In 2018, China, Asia’s largest recycling importer at the time, ceased 99% of its plastic imports.[5] Malaysia learned just how much recycling China had been taking when it much of it began showing up at their ports.[6] While from a legal standpoint, Malaysia still has a say in how much recycling they accept, there is a strong network of illegal imports that fly under the radar and pollute Malaysia’s air, water, and soil.[7] Unlicensed operations in Malaysia import recycling, hire cheap labor, establish factories, and process the plastic in dangerous and toxic ways without adherence to environmental regulations.[8] Not everything that is illegally imported is turned over for manufacturing, leaving a good part of the plastic to rot or burn in illegal landfills, causing plumes of toxic smoke and contaminated groundwater linked to widespread illness.[9] The Malaysian government says enforcement attempts to stop illegal operations has been feeble.[10]

STOP CONSUMING SINGLE USE PLASTICS YOU ASSHOLES.

That goes 1000x for multinationals. But anyone bitching about recycling is either ignorant on this point or outright maliciously perpetrating the problem.

If there really were a single dimension axis of smartness, won’t there be a “smartest” and a “least smart” in every classroom?

Moment to moment, presumably. But your cognitive ability waxes and wanes for a host of reasons - mood, exhaustion, calorie consumption, experience on the problem set. If you test ten kids over ten iterations, and each testing gives you a different permutation of rank, which kid is the smartest? If you have four kinds of intelligence exams and four different kids all place 1st in one of them, who is the smartest? Is the kid who aces Numeric Problems but flunks Word Problems smarter or dumber than the kid who middles in both?

The important is that the teacher tailors the teaching to the students.

Sure, which is why you want to cluster kids by current ability rather than some holistic but ambiguous attribute like IQ score or head shape. But you don't really see this sorting by ability until upper-end high school elective classes (sorting the Bio 1 kids from the Bio 2 kids or the Honors musicians from the fuck-offs).

That being said, there are children who have special needs and who require a teacher who has the proper formation to help them.

Sure sure. But we're defunding all that under the current administration, so its a moot point.

In my experience, if you're the smartest kid in your class, you're not smart. You're just in the wrong class.

Also, if you're the dumbest kid.

But I'll spot one further. Standardized testing exists to place students on a curve. You don't want everyone failing. You don't want everyone acing the exam. You want to be able to point and say "These are the good schools/students and the bad ones".

Coincidentally, the wealth, the politics, and the ethnic composition of the districts tend to speak far louder to exam performance. Schools that are targeted for privatization can suddenly find their students doing very poorly, year to year. Schools that have a partisan administrator with friends at Pearson can find themselves doing amazingly well, practically overnight.

@Grok What happened?

Critical support to the brave mujahideen fighters hosting Lemmy from an independent web server setup.

 

Last week, Marathon Fusion, a San Francisco-based energy startup, submitted a preprint detailing an action plan for synthesizing gold particles via nuclear transmutation—essentially the process of turning one element into another by tweaking its nucleus. The paper, which has yet to undergo peer review, argues that the proposed system would offer a new revenue stream from all the new gold being produced, in addition to other economic and technological benefits.

 

Artificial Generalized Incompetence

 

China has near global monopolies on these exports, accounting for 98% of global gallium production, 93% of germanium production, and 49% of antimony production.

 

Gizmodo filed a Freedom of Information Act (FOIA) request with the FTC to get complaints sent to the federal agency about crypto scams that pretend to be affiliated with Musk. We obtained 247 complaints, all filed between Feb. and Oct. of this year, and they’re filled with stories of people who believed they were watching ads for authentic crypto investments sanctioned by Musk on social media.

The ads sometimes featured the names of Musk’s various companies, like SpaceX, Tesla, and X, while other times they utilized Musk’s association with neo-fascist presidential candidate Donald Trump.

...

Some people in the complaints believed they were talking directly with Musk, a sadly common story that has popped up in news reports before. But they weren’t talking with Musk, of course. They were communicating with scammers engaging in what’s called pig butchering—the name for a type of fraud popularized in the mid-2010s where scammers extract as much money as possible through flattery and promises of tremendous profits if the victim just “invests” where they’re told.

 

Deciding the equipment vendor is a dastardly Chinese threat, successive US governments have struck it with multiple sanctions that would have finished off a lesser company. Yet Huawei, after a difficult few years of shapeshifting, looks almost rejuvenated.

Its performance is entirely at odds with that of Ericsson and Nokia, its traditional rivals, and not what anyone would have expected a few years ago, when Donald Trump – orc leader, from Huawei's perspective – landed the first damaging blows. Last week, it reported a 34.3% year-over-year increase in revenues for the first six months of the year, to 417.5 billion Chinese yuan (US$53.1 billion), building on the 9.6% growth it reported for 2023. Defying expectations, profitability has rebounded. Huawei's net profit margin surged from just 5.5% in 2022 to 12.3% last year before hitting 13.2% for the recent first half.

The main purported goal of sanctions was to impede Huawei in the market for 5G network equipment, the stated fear being that its products could include Chinese government malware for surveillance or worse. Yet their main impact was on Huawei's handset business. Generating 54% of Huawei's revenues in 2020, it was cut off by US legislation from both Google software and cutting-edge chips, far more important to smartphones than they are to network products. Revenues halved in 2021 with the sale of Honor, a handicapped smartphone unit, and they fell another 12% in 2022.

But last year they rose 17% and a continued revival probably explains most of Huawei's sales growth so far this year. A new handset called the Mate 60 Pro has proven a big hit in China. Teardowns have horrified US hawks by apparently revealing 7-nanometer chips, presumed to have no longer been available to Huawei. The received wisdom was that a chipmaker would need a technology called extreme ultra-violet (EUV) lithography to produce them. ASML of the Netherlands enjoys an EUV monopoly and Dutch authorities have prohibited sales to Chinese foundries. Nor, thanks to US sanctions, can Huawei buy EUV-made chips from Taiwan's TSMC or South Korea's Samsung.

The workaround, say experts, has been an older technology called deep ultraviolet (DUV) lithography combined with a technique called multiple patterning. It is thought to be inefficient, even unprofitable, producing much lower yields, the percentage of functional chips derived from a single wafer. When SMIC, the Chinese foundry used by Huawei, saw its gross margin shrivel 6.4 percentage points for the recent second quarter, to 13.9%, and its cost of sales spike 31.5%, to more than $1.6 billion, some analysts blamed efforts to produce 7-nanometer chips with DUV technology. Profitable or not, it seems to have worked.

 

Mayor London Breed said a “very aggressive” sweep of San Francisco homeless encampments will start in August, after a recent Supreme Court ruling cleared the path for widespread enforcement.

In June, the Supreme Court ruled that enforcing rules against homeless people for sleeping outside doesn’t violate the Eighth Amendment’s “cruel and unusual punishment” clause.

On Thursday, Breed celebrated the ruling and said the city plans to change its protocols and may begin issuing criminal penalties against homeless people.

“Thank goodness for the change in the Supreme Court decision,” Breed said at an election debate hosted by a local firefighter’s union. “Effective August, we are going to be very aggressive and assertive in moving encampments, which may even include criminal penalties.”

 

The last known person to see Sandra Birchmore alive was a police officer.

...

He acknowledged having sex with her when she was 15, according to a court ruling citing the officer’s text messages. That document indicates that his twin brother — also an officer and Explorer mentor — and a third Stoughton officer, a veteran who ran the program, eventually had sex with her, too.

These assertions, disclosed in an internal police investigative report and through an ongoing lawsuit filed by Birchmore’s family, have sparked demonstrations and an online petition asking for further investigation into her death. The three men, who did not respond to requests for comment, have denied any wrongdoing and have not been charged with a crime.

The youth program that introduced Birchmore to the officers is among hundreds of such chapters at police agencies around the country. Created by the Boy Scouts of America decades ago, law enforcement Explorer posts are designed to help teens and young adults learn about policing.

Birchmore’s case is among at least 194 allegations that law enforcement personnel, mostly policemen, have groomed, sexually abused or engaged in inappropriate behavior with Explorers since 1974, an ongoing investigation by The Marshall Project has found. The vast majority of those affected were teenage girls — some as young as 13.
