Super interesting, I wonder if this research will cause them to actually change their llm, like turning down the ”desperation neurons” to stop Claude from creating implementations for making a specific tests pass etc.

I think you can actually replace crypto with LLMs/Diffusion models in this sentence and it will still hold true

It is if you just check the sources, heres the json: ``` [ { "name": "Nematode", "emoji": "", "pop": 5e19, "category": "Roundworm (Invertebrate)", "fact": "There are roughly 57 billion nematodes for every human on Earth.

Terraform is not an abstraction on top of multiple cloud providers, you work with aws, azure etc explicitly. It is , however, agnostic in the sense that you can provision aws, azure, gcp, etc resources within the same iac project

Never understood why you’d use sdkman for Java. I just do:

1. brew install openjdk@

2. ln -s

3. /libexec/java_home -v

Afaik, with some aliases in you *shrc it basically reimplements sdkman, what else does it give you?

I don’t understand how to work with the intermediate language in such a back-to-front approach, wouldn’t you need to know in advance what pass to implement next so that the input to the current pass matches the output of your next, unimplemented, pass? To me, it seems like the contract is reversed

New comment by emoII in "When if is just a function"

emoII — Sat, 18 Oct 2025 12:04:27 +0000

You're correct, that is lazy evaluation. The entire article talks about lazy evaluation without mentioning it, which was my point

New comment by emoII in "When if is just a function"

emoII — Sat, 18 Oct 2025 10:15:47 +0000

Interesting that this article makes no mention of eager vs lazy evaluation - isn’t a big reason that if, for etc has to be special forms in an eagerly evaluated language that their arguments need to be lazily evaluated, which of course, deviates from the rule? Also, lazy evaluation is achieved in an eagerly evaluated language as simply wrapping a block of code in a function, which makes lazy evaluation isomorphic with the contents of the article

This is a fun one I think:

- Use dark mode

- Go to wikipedia (or any white page)

- Open the keyboard

- Watch the keyboard start in light mode and then resize very weirdly within its container as it switches to dark mode

Atleast it does on an iphone 12
