I have to remember that my chest pain condition is called Precordial Catch Syndrome (PCS). It's scary and strange but benign. It started when I was 14 years old with occasional recurrences now and then at different times in my life. (1/2)

There are no nontrivial context-free physical objects.

The trivial ones are the world and nothingness.

This seems important.

Un terrain de foot = un hectare = 10,000 m²
You're welcome
120 × 80 = 9600 m² = un hectare environ pour toute la pelouse. C'est le chiffre que je vais retenir 😀

Hypothesis: writing and maintaining code is easier—can be done with simpler designs—if you and all your current and future collaborators have great memory.
While we're at it, It could also design libraries and tools to target LLMs i.e. programmers with immense knowledge but shallow intelligence.

Someone who's not me should have an AI write the whole standard library and all the dev tools for this language.

(definitely not #ocaml)
i honestly don't get how you can make a functional programming language in 2025 where the only data structures in its standard library are lists, (somehow worse) difference lists, immutable arrays and binary search trees

I'm experimenting with pairing my concise notes with longer explainers written by ChatGPT. Here's one:

"There's no correct perception"

Let me know how you feel about this.

After spending an evening shopping for a walking treadmill and giving up upon learning that they consume over 2000 watts and then briefly considering a manual treadmill, I find myself looking for something simpler to encourage movement at my standing desk. Suggestions welcome!

I made an awesome playlist for my nephew based on L'Aventurier by Indochine. Enjoy if you dare!

I have way too many fun and good projects for this Thanksgiving weekend and upcoming Christmas break. I'm not sure if I should do a little bit of each kind at the risk of spreading thin or go all in on one project. Maybe I'll pick one big project and several tiny ones for easy wins.

To be clear, there are way better explanations of entropy if you need one. I'm a little fuzzy on the limits of its applicability in physics, though.
Explain entropy:
Everything eventually turns to shit and evens out—but here and there, highly organized anti-shit emerges producing even more shit around it in the process.

Revenge is not ok. It never is.
Ask for payback or forgive but do not destroy value.

Please say something when you witness vengeful behavior, especially when directed at OCaml community members, regardless of how wrong or annoying they may be on some issue.
#ocaml
I don't quite understand why 19 people downvoted the apology note and nobody gave it a thumbs-up (I believe this was before the PR was closed because emoji reactions are now locked). This kind of mob behavior is not typical of the OCaml community and is concerning. #OCaml

Fast mass transportation in dense environments benefits from constrained and coupled trajectories. That's why in cities, trains work better than cars and cars work better than helicopters (unless you have the sky to yourself, obviously).

Last year, I learned that my birthday is also the anniversary of the first synthesis of LSD by Albert Hofmann (1938). This year, I learned it's also the birthday of Terence McKenna (1946). Is it a coincidence or is it a message from the mushroom aliens?
