To build this dam, engineers first drowned a waterfall twice the size of Niagara. You could hear it roaring from 20 miles away. Then they made one of the world's biggest rivers move out of the way, just to clear room for the construction site. It's the Itaipu Dam, on the Paraná River where Brazil meets Paraguay. Work started in 1975, and the first job was the river itself. Crews spent three years carving a 1.2-mile channel through solid bedrock, 500 feet wide and 300 feet deep. They hauled away 50 million tons of earth. In October 1978, they set off 58 tons of dynamite, forcing the Paraná into a brand new path. Only then could the dam itself start to rise. The structure ate roughly five times the concrete used for the Hoover Dam, plus enough steel to rebuild the Eiffel Tower 380 times over. On one day in November 1978, the site poured concrete fast enough to put up a 10-story apartment building every hour for 24 hours straight. The main wall is 643 feet tall, the height of a 65-story tower. It runs almost 5 miles across the river. The bill came to $19.6 billion in 1970s money, roughly $60 billion today. About 40,000 people lost their homes when the reservoir filled. And in October 1982, when the water rose in just 14 days, it drowned Guaíra Falls, a chain of 18 waterfalls on the Brazil-Paraguay border that carried double the water of Niagara. Months earlier, a footbridge over the falls had collapsed under crowds of last-look tourists. Twenty-six died. In 2016, the dam produced as much electricity in a single year as New York City uses in two. That set a world record only broken in 2020 by China's Three Gorges Dam, which has 60% more generating power but sits on a river that runs low for half the year. Since 1984, Itaipu has put out more electricity than any single power plant in human history. It supplies around 90% of Paraguay's electricity and roughly 10% of Brazil's, from one wall of concrete. The final construction loan was paid off in February 2023, almost 50 years after the treaty was signed.

@OrevaZSN You reduce crime by locking up or executing criminals. Reference: El Salvador, the last few years.

You reduce crime by eliminating poverty. The reason so called nice neighborhoods have lower crime rates is because people’s basic needs are being met. It is not because of police, alarm systems, or neighborhood associations. Poverty creates crime.

@levelsio Let me add Delft to the list. Beautiful town square, picturesque canals, and lots of college students to contribute positive energy.

Leiden might be the best candidate if you want to visit a Dutch city and avoid the tourist shithole that Amsterdam is in 2026 (I am Dutch and from Amsterdam) Leiden is in some way might be more historically significant than Amsterdam (more on that in my reply) You'll find zero tourists and as a tourist you won't even be able to see the difference with Amsterdam (except that there's no annoying tourists!)

@denisyurchak I'd recommend instead going to other Dutch cities like Utrecht or Leiden which also have cute canals but aren't tourist shitholes As a Dutch

I’m currently at 60°N latitude. Starlink coverage gets kind of skinny up here. Slower speeds, higher latency, lots of video buffering. Still freakin’ magic, though.

A Mom in Tulsa called 3 health systems last week asking the price of her son's tonsillectomy. Health system A: "We cannot quote you a price." Health system B: "Pricing depends on your insurance." Health system C: "Our financial counselor will reach out after the procedure." No other industry in America gets to operate this way. Imagine ordering at a restaurant and getting the bill six weeks after dinner.

By the way, let me be clear about this: if you’re serious about teaching your kids how to read properly in English, you *must* use texts and books published before the 1960s. No, this is not about rejecting modernity, this is about making sure your kids can learn to read a wide variety of sentence structures as well as a wide enough vocabulary scope. It’s ridiculous that my 6yo can read much harder texts than most English speaking kids her age just because she learned decoding and blending in French before doing so in English. As a bilingual kid juggling with two sets of phonetics rules, she should be late compared to her peers, not well ahead of them.
Rachel V@RachelVT42

Whole language teaching methodologies have done so much damage it’s not even funny. Millions and millions of kids are basically illiterate because of it, and the tragic truth is that most adults blindly trust these methods like gospel because they don’t know any better. If you were born in the English speaking world after the 60s, the chances are, you’re completely unaware of how reading and decoding should be taught. I get it, English is a very complex language when it comes to the correspondence between phonemes and graphemes. But still, robbing so many kids of the necessary foundational knowledge they need in order to master their mother tongue is criminal.

There's an UNBELIEVABLE use case for regional trips in the US that will decimate air travel and buses. Fully autonomous Tesla Robovans outfitted as long-haul first-class "buses". These would run routes similar to Amtrak or Greyhounds, but with First-Class-like comfort, amenities, and space. The price per seat of these can be the same as a bus, but FAR more comfortable and FAR more luxurious. Can obviously optimize the interior for the best configuration but MAN. This would absolutely KILL.

By 1900, the United States had achieved a 90% literacy rate largely by using McGuffey Readers in one-room schoolhouses.  But, yeah, NYC’s problem is it’s not spending enough money.

Speaking of low G, what FAM is missing is people carrying riculously heavy things or jumping ridiculously high in the air at times. And not just on motorcycles. Ed is old and weak, but would be cool to have a doctor comment on how he'd be in a wheel chair on Earth.

Adults do not truly understand just how devastating whole language was to the education of our populace. So many children/teens cannot read fluently. It’s why graphic novels like Dogman are the choice for most kids in elementary/middle, because they cannot read well without visual cues. And even the high school and college kids hardly read independently, they listen to audio books, or read in class. Being able to read a sophisticated text independently and develop your own independent thoughts free of anyone else’s corruption is a skill that built this country. Will this younger generation have the capacity to able to be free thinkers?

Dude, if we get actually good mechanized picked tea, it's gonna be a gamechanger. The American south will absolutely wreck global tea production. The labor cost bottleneck has been prohibitive for American tea, and using a cutter to harvest is a big quality loss. An actual leaf-plucker robot would allow capital-deep American farmers to get in the game on a crop which is extremely well-suited to the climate of the southeast-- so much so that its close genetic relative, the camellia flowers, grows wild without assistance!
People's Daily, China@PDChina

A humanoid robot is learning to pick tender tea leaves under the guidance of workers at a West Lake Longjing tea plantation in Hangzhou, east China’s Zhejiang Province. With AI recognition models and algorithms, the robot is capable of identifying and locating leaves that meet harvesting standards.

$10 trillion. Just think how many nuclear power plants we could have built. That would have enabled the full electrification of our power grid. It would have reduced carbon emissions by billions of tons. All misspent for a "green" fantasy.

Muslims in the West are caught on the horns of a dilemma when asked why they’re here. If they say, “for a better life,” they’re admitting the West is best. If they say, “to conquer the West for Islam,” they’re confessing to violent revolutionary motives.

They don’t teach that from 1920-1970, the US had severely restricted immigration… In those 50 years we won WW2, became a global economic and military superpower, created a booming economy, a thriving middle class and a strong common culture. The America everyone talks about.

“If you do not work on an important problem you are unlikely to do important work.”
Millie Marconi@MillieMarconnni

A mathematician at Bell Labs noticed that the scientists who won Nobel Prizes and the ones who never amounted to anything were equally smart, equally hardworking, and equally credentialed, and the only thing that separated them was a single question almost nobody is brave enough to ask themselves before they die. His name was Richard Hamming. He spent 30 years at Bell Labs, in the same building as John Tukey, Walter Brattain, and a long list of physicists who took home Nobel prizes for work they did down the hall from his office, including the legendary Claude Shannon. His invention of error-correcting codes made modern computing possible. He has won the Turing Award. And all the while he was creating his own legacy he was secretly doing a study on the people around him. The study was straightforward. 2 Teams. The legends and the lost. Same I.Q.s. Degrees same. Same desk hours. Same access to the world’s best resources. And yet, at the end of 40 years in their careers, one group had changed entire fields, and the other group could not be remembered by their own colleagues five years after retirement. He wanted to discover what the actual difference was. In March 1986, he stood before 200 researchers in a Bellcore auditorium and told them what he had seen. He said it all came down to one question. And hardly anyone he ever met was willing to ask it directly. He called it the Friday-afternoon ritual. He spent years blocking out his Friday afternoons and not doing anything productive with them every week. No experiments. No meetings. No deliverables. He called it Great Thoughts Time. He sat down with a notebook and asked himself a couple of questions in order. What are the most relevant problems in my discipline? And why I am not working on either of them.” Most weeks, the answer was the same, he said. For a week now he had marched confidently in a direction he did not think was the most important direction. He was a goer. He worked a bit. He was getting clean results that would publish in respected journals. ( And for five days straight he'd been lying to himself about whether any of it mattered. The reason almost nobody does this ritual is because the honest answer is unbearable. The thing is that if you sit down on a Friday afternoon and say out loud that you are not working on the most important problem in your field, now you have to do something about it. You have an immediate change in direction, or you have to keep lying to yourself every week from that point on. Most people choose the lie. In the short term it’s cheaper, but over a career it’s more expensive. Hamming took the ritual a step further in the Bell Labs cafeteria. He began approaching scientists he barely knew, asking them what they thought the most important problems in their field were. A week later he would ask them why they had not worked on these problems. Eventually people wouldn't have lunch with him. “I had to keep finding new tables,” he said. Nobody had a good answer for that, and being around someone who kept asking it made every meal feel like a performance review. The line that broke me is the line that most people skim over in the transcript. His words: If you do not work on an important problem you are unlikely to do important work. That’s not motivational line. It is a rational one. You cannot make a great result from a problem that does not matter. Input restricts the output. The choice of the problem is the ceiling of the career. The transcript has been freely available on the internet for almost 40 years. Stripe Press published the complete lectures as a book. Naval Ravikant quotes it all the time. It’s still given out to new hires at every serious engineering lab in Silicon Valley. Most people will not run the ritual this Friday. They will be busy. They always are.

Hey @grok I haven’t heard about Grokipedia lately. Questions: (1) Is the number of articles still growing, and what are their statistics? (2) What about web traffic? (3) What are the main challenges grokipedia must overcome to attain widespread use, and what’s the prognosis?
