Throwing rubbish in a landfill is (usually) better for the environment than recycling it. With few exceptions, recycling ends up emitting more CO2 and costing more money, while landfills are cheap and secure. - Recycling mid-tier plastics (like plastic bottles or butter tubs) costs thousands of dollars per ton of CO2 saved. It's cheaper to do direct air CO2 capture than that! And there is no shortage of plastic, nor any problem with sequestering it in the ground once we're done with it. - Modern landfills are extraordinarily secure and are *much* more than just big piles of trash. They capture 75%–95% of methane gas. Groundwater contamination is doesn't really happen with landfills built since 1990. A study of 31 landfills built since 1988 in NY found no adverse effect at all on local groundwater quality. - The crusade against single-use plastics has driven us to products that use far more materials and energy and would need to be used an absurd number of times to actually be an improvement. A steel straw needs to be used 150 times to be worth using. A ceramic mug needs to be used 1,000 times to beat a polystyrene cup. A cotton bag needs to be reused 173 times to beat single-use. - Some things ARE worth recycling. Recycling metal saves a huge amount of energy and material – recycling aluminium saves 95% of the energy spent on making fresh stuff. So we do a lot of it already: about 30% of steel worldwide is recycled. Modern, well-run landfills cause minimal environmental damage. We have plenty of space for them – less than 0.01% of the US is used for landfill and only about 0.02% of Germany. We can even build on top of old landfills, so the land area is not spent permanently. New in @WorksInProgMag, @robertwiblin and @chalmermagne on why it's usually best to just bury your trash. worksinprogress.co/issue/jus…

We have special news! 3 white-tailed eagles have fledged from wild nests in Dorset & Sussex this summer. With 5 pairs now established across England we hope to see further breeding in the coming years as this lost species is restored. bit.ly/4h83z3D @RoyDennisWF

I need your help: I want to get more people into the WikiCritic beta-test. The launch will be huge, and you'll have bragging rights! How? It's easy. I've screenshotted some Wikipedia article introductions below. Post a review of JUST THIS (the "lede") below! 🧵👇

Phenomenal PISA scores show forty years of education reforms in England under successive governments worked. Standards up. In Scotland and Wales they shunned reforms and the price is paid in squandered human capital and potential. open.substack.com/pub/reacti…

Suffering for over 15 years with a rare brain tumour, I went to countless doctors who told me nothing was wrong with me. They would say I was stressed, or needed to sleep more, exercise more, misdiagnosed with PCOS 3 times. These were NHS and private doctors. Specialists.

Less than 100 miles away, about 50 tons of steel and copper are spinning at exactly 3,600 RPM. A giant rotor slews magnetic fields through copper windings and, per Faraday and Maxwell, induces a synchronized 60 Hz sine wave across an entire grid. That electromagnetic wave propagates through grain oriented silicon steel, laminated transformer cores, kilometers of aluminum conductor steel reinforced cable, SF₆ insulated switchgear, substations switching hundreds of kilovolts, distribution transformers, oxygen free copper wiring, silicon MOSFETs, ferrites, multilayer ceramic capacitors, and the USB C cable plugged into my phone. There, power feeds a capacitive touchscreen. A transparent matrix of indium tin oxide is deposited on glass. The controller continuously scans the grid. My finger changes the mutual capacitance by a fraction of a picofarad, perturbing the local electric field just enough for dedicated analog front ends to detect before software reconstructs the touch. Iron ore. Bauxite. Silica sand. Copper ore. Lithium brines. Rare earths. Refined. Alloyed. Crystallized. Doped. Implanted. Deposited. Etched. Polished. We purified sand into nearly perfect single crystal silicon, grew boules, sliced wafers, placed dopant atoms with nanometer precision, fabricated chips containing tens of billions of transistors, synchronized them with clocks billions of times per second, and engineered them to execute matrix multiplications at a scale no human could comprehend. Somewhere along the way, matmuls started to look like us. That is an astonishing thought. The towers of abstraction are staggering. No one person built this. No one person fully understands it. Yet every morning millions of people wake up tired, answer emails, argue over specifications, chase margins, fix defects, make payroll, and try to cover their mortgages. Somehow the whole machine keeps humming. A planetary Swiss watch assembled from physics, markets, bureaucracy, ambition, error, and human necessity. And after all of that, I touch a piece of conductive glass and step into the Roman forum of modern thought, where millions of minds test ideas against one another in real time. Clockwork humanity. It staggers the mind.

I always thought I had a pretty good eye. Studied fine arts. Good at spotting patterns. Pretty observant. Then I found this account. Whoever runs it sees things I didn’t even know could be seen.

Useless machines, first conceived around 1952 by Marvin Minsky while at Bell Labs, are fully functional machines designed to perform exactly nothing useful. 📽: fritend1

Take a look at your favourite skill. Go on, take a look. Check for lines like: - "Make the commit message very detailed" - "Be thorough" - "Make the implementation easy to read" What do these lines have in common? They're no-ops. They do nothing to change the agent's behavior. Agents always write good commit messages. They always try to be thorough. They always try to create easy-to-read implementations. Try removing them. Does the output change? No? Then the line was a no-op. Agent-authored skills are LITTERED with no-ops. Entire paragraphs and sections of text that does nothing to change the agents' behavior. No-ops make skills harder to evaluate, harder to maintain, and burn tokens uselessly. Learn to spot them, test them, and remove them. Your skills will thank you.

So here's an early 19th century children's book titled "Marmaduke Multiply's Merry Method of Making Minor Mathematicians," and it's about as insane as you'd think.

Replying to @steipete
I think what Peter means by “loops instead of prompts” is this: Stop trying to write the perfect prompt. Give Codex a repeatable engineering loop: Read → Plan → Implement → Build → Test → Fix → Repeat The prompt becomes almost irrelevant once the project contains: * PROJECT.md * ARCHITECTURE.md * DECISIONS.md * TASKS.md Now the AI isn’t guessing what to do. It’s operating inside a system that continuously validates its own work. The real productivity gain comes from the loop, not the prompt.

Machine guns forced armies into trenches. The evolution of warfare in the drone era…tunnels. The battlefield at the surface has become transparent and vulnerable, as anything that moves in the open can be seen and attacked cheaply. The contested kill zones in Ukraine now extend as deep as 15 miles on either side of the front. The logical response is to go underground. This plays out three ways: Critical infrastructure gets buried bc a desalination plant or substation can’t survive in the open anymore. Defenders pre-build tunnel networks behind the front, turning a whole region into fortified area that attackers can't easily cross or hold. While attackers try to dig under the kill zone to turn a long exposed advance into a short protected one. Traditionally the cost of tunneling has been prohibitive for anything but the most valuable use cases. But drop that cost far enough and you expose enormous latent demand, and the underground becomes routine military infrastructure. In the same way that SpaceX didn’t just make existing use cases cheaper but created entirely new ones that weren’t practical before. Almost like Elon saw this coming when he founded The Boring Company. Full thesis to follow if there's interest.
