Panels one and two: Two white mice make their way through a maze. Panel three: Having completed the maze, the two mice are rewarded with some fruit. Two scientists watch them. One says: “Poor little things: all that thought and effort just to earn themselves a little treat.” The second scientist looks at a clock and says: “Coffee time!” Panels four and five: The two scientists make their way through a maze of corridors to a door marked “Canteen” Panel six: The scientists look at the food on offer. One says: “Ooh, Donuts!”

A good read on the experiences (good and bad) of coding with LLMs:

If you know anything about programming, this is hilarious (you don't even have to know JavaScript - I don't, but there were so many WTAF:s here 🤣)

I enjoyed the Netflix series "Pretend It's a City" (from 2021), where Martin Scorsese lets Fran Lebowitz answer questions on a range of subjects. Full of witty one-liners, and very New York. Seven half-hour episodes, quite entertaining.

I really enjoyed the two recent episodes on The Rolling Stones on the "The Rest Is History"-podcast. Historical and social context, as well as lots of interesting facts about the band. And (as always) articulate and witty hosts. A joy to listen to.

This document, The Power of Ten – Rules for Developing Safety Critical Code (from NASA/JPL Laboratory for Reliable Software), came up at work. Interesting to read and discuss, even if you don't code in C, and even if you don't agree with everything in it.

The Deep Research problem — Benedict Evans OpenAI’s Deep Research is built for me, and I can’t use it. It’s another amazing demo, until it breaks. But it breaks in really interesting ways.

Very interesting post from @benedictevans.bsky.social on the problems with LLM-backed "deep research" features:
