At the risk of starting the flame war to end all flame wars... Modern LLMs (GPT-5.1, Claude 4.5, Gemini 3) produce excellent code and can be a significant productivity boost to software engineers who take the time to learn how to effectively apply them - especially if used with coding agent tools

“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

🇪🇺🇺🇦 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.

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.

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. papers.ssrn.com/sol3/papers....

Here's why air-conditioning is the wrong climate villain.

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?

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.”

Greg Jennings is the VP of Engineering and AI at @anacondainc.bsky.social. He joins the podcast with @kball.llc to talk about the tooling ecosystem around AI app development, the Anaconda Toolbox, the rapidly evolving role of AI in engineering, and more. @gregjennings.bsky.social bit.ly/3GpDv5T

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.

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: foreignpolicy.com/2022/01/16/c...

Hooked my LLM agent (github.com/simonw/llm + my own python function to interact with google calendar/Asana etc.) with Alfred so that I can select an area on my macOS desktop, then prompt LLM to add it to my calendar.

Stunning details now emerging: this was an operation planned a year and a half in advance, involved smuggling drones into Russia, placing them in containers on top of trucks, arranging for them all to open simultaneously and to strike.
