This is an area I am happy to admit I was wrong. I thought the way to get more people to use this stuff was lowering the price and not enforcing petty crimes. Turns out a super data driven approach was the right way and preventing free riders made all the difference

BART spent $90 million on new fare gates. They're recovering about $10 million a year in fares. That's a 9-year payback on paper. The actual return hit in six months. Embarcadero station went from 112 hours of corrective maintenance in the six months before installation to 2 hours after. Daly City saved 109. Balboa Park saved 75. Across the system, 961 hours of cleanup work disappeared. Corrective maintenance is the term BART uses for graffiti, heavy soiling, vandalism, the damage that needs a crew not a janitor. At several stations it dropped to zero. Crime fell 41% year over year. Riders who reported seeing fare evasion on their trip dropped from 22% to 10%. Citations issued by BART police went from 2,200 in January to under 1,000 in July, because there was nothing to cite. The gates were a filtering project disguised as a revenue project. Old BART gates were waist-high orange fins designed in the 1970s. You could hop them in under a second. That made the station effectively a public space, and the rider mix reflected that. The new gates are 72 inches of polycarbonate with 3D sensors that detect tailgating. You either pay or you don't enter. Once you don't enter, you also don't smoke on the platform, sleep in the elevator, or harass other riders. BART tried hiring more police for years. Blitz operations at high-traffic stations. Increased patrols. Dedicated transit cops. None of it moved the numbers the way six feet of polycarbonate did. The $10 million in recovered fares is the smallest line in the return. Fare revenue used to cover 70% of BART operations. After the pandemic it collapsed to 22%. The gates won't fix that gap directly. They fix the precondition for fixing it: a system that office workers, families, and tourists are willing to use again. Ridership growth at stations with new gates outpaced ungated ones before the rollout finished. A $400 million annual deficit is heading to voters in November as a sales tax measure. Voters don't approve sales taxes for transit agencies they don't feel safe in. The $90 million on gates is buying BART the right to ask the public for more money. That's the real return on six feet of polycarbonate.

@ChrisHatt11 @1TrueRicardo Embarrassingly it’s exactly the opposite. A critical ingredient in catalytic converters, which are only relevant in the ICE era.

One Ukrainian drone entrepreneur I talked to claimed that China could currently produce a billion weaponized drones per year if they wanted to. This number will only go up. But go grab your little shotgun, I guess
Noah Smith 🐇🇺🇸🇺🇦🇹🇼@Noahpinion

Talked to some Ukrainians. They confirmed a shotgun is the best man-portable drone defense. But what that means is that it takes 2 drones to kill a man instead of 1. They told me about one Russian soldier who shot down 7 drones before they got him. They nicknamed him "Rambo".

Earth Day 2026; on a planet where warming is accelerating, Earth loses resilience, 7 of 9 planetary boundaries breached - is a reminder we cannot exclude pushing our "blue dot" along a Hothouse Earth path, drifting towards a less and less liveable home. sciencedirect.com/science/articl…

A single GPU can now calculate hundreds of global weather scenarios in under 60 seconds. The exact same task requires a supercomputer and hours of brute-force physics. Google DeepMind recently released WeatherNext 2. The model beats the previous state-of-the-art system on 99.9% of weather variables across a 15-day forecast window. It achieves this massive jump in accuracy using a new modelling approach called a Functional Generative Network. Meteorologists categorise weather data into two buckets: 1. Marginals are isolated data points, like the precise temperature at a specific location or the wind speed at a certain altitude. 2. Joints are the massive, interconnected systems that form when all those individual elements interact. The researchers hid the joint systems from the model during training. They only taught it the isolated marginals. When they turned it on, the model skillfully predicted the massive, complex systems anyway. The architecture forces an 87-million-dimensional output distribution through a 32-dimensional mathematical bottleneck. To survive this severe constraint and still produce accurate individual data points, the neural network has no choice but to learn the underlying physics linking everything together. It figures out the weather because that’s the most efficient way to solve the maths. The practical results are immediate. The model gives forecasters a full 24-hour advantage in tropical cyclone tracking compared to the previous leading system. It maps extreme wind speeds and heatwaves with unprecedented precision. We’re watching a pretty big shift in predictive capabilities. The machine is deducing the structural reality of planetary weather from isolated fragments of data.

Only one chance in this lifetime… Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him. I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.

There’s a famous story about a rabbi who survived the Holocaust, camps and all, while his entire family was killed. When he returned home, he said, “It could have been worse.” His students asked: “How could it possibly have been worse?” The rabbi replied: “It could have been us doing all the killing.”

Bicycling is the most efficient mode of transportation. Humans on bikes burn the least amount of energy per gram of weight per kilometer of travel any other animal or technology.
Michael Easter tweet media
critical urbanism@criticalurban

Bikes are objectively inferior transportation by every metric. Slow, minimal carrying capacity. Can't carry passengers. Exposed to the elements, the rain, snow, sleet, heat, and cold. It's awful. Incapable of practical regional access.

This is a strong Glasgow team. The Lions have utterly routed them. An annihilation from the word go. Best performance from the Lions in possibly 10 years.
