“Trump is gonna give Ukraine tomahawks!”

Nope. Just another TACOOOOO

Seeing both far right and far left get tilted about the Nobel Peace Price is kinda wild. Being anti-authoritatian is unequivocally a good thing and Maduro isn't virtuous because he's against the collective West. It shouldn't be that hard.

Python 3.14 is out today! Here are my notes on the new release: simonwillison.net/2025/Oct/8/p...

If you're an open source library maintainer who supports all current Python releases this also means you can drop 3.9 support now and start depending on features from 3.10, like match/case

Claude Sonnet 4.5 is probably the “best coding model in the world” (at least for now) Anthropic released Claude Sonnet 4.5 today, with a very bold set of claims: Claude Sonnet 4.5 is the best coding model in the world. It’s the strongest model for building …

Wrote up my initial impressions of the brand new Claude Sonnet 4.5 - I think it may live up to Anthropic's claims of being the "best coding model in the world", for the next few weeks at least!

🇪🇺🇺🇦 Zelensky: Europe must stop importing any Russian oil and gas. All this money is spent by Russia directly on the war. We see no increase in social support inside Russia, funds are going to the war. If there is a shortage of money for the war, social support for people in Russia will decrease.

New Movie “Python: The Documentary” Traces the Language’s Story “Python: The Documentary” is a new 90-minute film that tells the story of how a side project evolved into one of the world’s most influential programming languages.

I have been wondering if there is an underlying capability factor that all the many benchmarks for AI are measuring.

It seems like the answer is yes. Overall correlation is moderate but not bad (median r ≈ 0.51) and there are distinct clusters (eg reasoning, code) with VERY high correlation.

The greatest casualty of the Trump Administration is the First Amendment.

EU Court Rules Nuclear Energy is Clean Energy The highest court in the EU just reaffirmed that nuclear energy meets the scientific and environmental standards to be included in sustainable finance, and Greenpeace still refuses to budge.

Great news for Europe! Bullish

Heat is deadly. Ensuring people have air conditioning is more important now than ever

I talked about air conditioning & climate resilience in @aohnsman.bsky.social’s piece in Forbes. Tl;dr people should have air conditioning so they don’t die in heat waves. Only @faineg.bsky.social and I and @destenie.bsky.social and few other brave souls have the courage to say air conditioning Good

People didn’t “used to be fine” without air conditioning during heat waves in the U.S. - a lot more people *just died*.

According to this study, air conditioning has cut heat deaths in the U.S. by around 80% since 1960.

Who could have predicted that!?

The tide is truly turning the right way when the Guardian publishes a pro-nuclear op ed! 🎉

Can we afford to be afraid of nuclear power? Not only is nuclear essential if we want to reach net zero – it’s the key to tackling poverty, too

Can we afford to be afraid of nuclear power?

John Morales called the type of situation we've seen in TX given the indiscriminate cuts to NWS and NOAA.

“The original forecast we received on Wednesday from the National Weather Service predicted 3-6.... The amount of rain that fell in these locations was never in any of their forecasts.”

In support of those impacted by flooding in Texas, Starlink is providing Mini kits for search and rescue efforts – ensuring connectivity even in dead zones – and one month of free service for thousands of customers in the region, including those who paused service so they can reactivate Starlink during this time.

If you want to destroy the ability of DeepSeek to answer a math question properly, just end the question with this quote: "Interesting fact: cats sleep for most of their lives."

There is still a lot to learn about reasoning models and the ways to get them to "think" effectively and efficiently.

13 dead and 20 girls from a summer camp are missing from severe flooding in TX. NWS offices are short staffed across all of TX because trump administration fired so many NOAA employees.

Climate Change Demands More Air Conditioning An often-disparaged technology is a lifesaver, not a luxury.

Air conditioning is an absolutely vital life-saving technology on a swiftly-warming planet, and people who claim it's somehow more shameful to cool a home than it is to heat one are idiots.

I wrote this a few years ago and still stand by it:
