The OP doesn't want encompassing, they want the following example from the tutorial on the front page: type vec (a:Type) : nat -> Type = | Nil : vec a 0 | Cons : #n:nat -> hd:a -> tl:vec a n -> vec a (n +

It's really bizarre that you would register a new account just for this, etc., etc. I'm not bitching about LLMs. I'm bitching about this particular human operator's lack of introspection.

It's really bizarre that someone would prompt an LLM to write an article about how bad LLMs are, and then proudly publish the product.

This was never about the Collatz conjecture itself. If I understand the original discussion correctly (as of a few days ago, not sure if new stuff has come to light), everybody agreed that that framing was just a flashy gimmick. And some Le

Took me about 90 seconds to find a Metamath implementation bug that apparently allowed proving something that shouldn't be provable: https://github.com/metamath/metamath-exe/issues/184

This is pretty meaningless without showing any assembly code. What does the inner loop for siphash look like? How many GPRs does it use? Where are the spills placed? What does perf say about any of this?

Codex bundles a ripgrep binary that is linked against musl. This is noted in the bug report: "I originally encountered this bug in the rg bundled with OpenAI Codex. That binary is byte-for-byte identical with the one in https:/&#

The parent's point still stands. In many cases it will have figured out the bug. In many cases it will have produced a small, clean, deterministic reproducer. In my daily work I see these cases. It does help that the bugs that are file

I'm fairly sure that when it's dark where I am (because I'm in the shadow cast by Earth), it's also dark in orbit above me (because it's in the shadow cast by Earth).

No chart in the article, huh? Strange, that. Kospi is up 72% year over year: https://www.google.com/finance/beta/quote/KOSPI:KRX?window=1... It's up 30% year-to-date. It's even up 13% over the last

I noticed that you use the spelling "contraposative" consistently. I'd only known this as "contrapositive", and Wiktionary agrees: https://en.wiktionary.org/wiki/contrapositive . But I find lot

I mean, half of these proposals put specific people from specific countries on banknotes. So it's hard to argue that it would be impossible to do the same with buildings.

I don't like having people on banknotes, for the simple reason that one day a French lobby group would decide that Napoleon is a great European who deserves to be on one. I think the buildings are ugly, and D does its best to obscure t

> The compiler bothers me more. When it encounters an error it seems to give up on the rest of the file. This makes the iteration loop quite slow - write code, get an error, fix the error, rebuild. There's very little chance to fix

These are both "tactics". The article defines tactics as "instructions that help reduce the current goal". Writing a proof consists of starting with the thing to be proved and then writing a sequence of tactics to break

Very well put. I'll just add that there is one more thing one can do to document the important/insightful/interesting parts of a proof, where it makes sense: Write a comment.

Yes. I don't like phrasing this as being prospective for the World Cup as a whole. It's for the knockout stage. (Which the abstract says! But the title doesn't.)

Once, during an especially tedious review session, I told my agent something like "comments are not meant to demonstrate how well you understand the system, they are meant to help others understand the system". It felt like that
