It is funny for now to be flamed by an agent:

But, if GitHub doesn't get a hang of this, and I don't envy them, people will stop using it.

AFAIK there is no C compiler in Rust. This would have been an achievement even if the model had direct access to GCC source code, but it didn’t. This is an ambitious, wierd research project done for curiosity that is honest about its limitations. Code literally says “do not use”.

The Claude C Compiler is extraordinary research result. However, most reactions read either like university press releases or Reviewer B.

I’m surprised this dent, which I could barely see and almost forgot about, required full door replacement and the other guy’s insurance more than 5K. Excellent job nevertheless.

Great article, and matches my experience exactly. I'm not quite sure what it takes to get a novice programmer to the point where they can use these tools like a master, while continuing to develop skills that I sharpened over decades.

There are these stupid “<advanced topic> for babies” books. Which are at best a joke for parents. Where is abstract algebra for babies?

Slopcoder is a web-based frontend to Claude Code, Codex, etc. that run on your local server. If you secure access to your server, you get the benefits of web-based access to agents, without the headache of configuring isolated environments on third-party infrastructure.

In the early 1990s, my grandfather purchased an original IBM PC with an aftermarket HDD. I first learned to program using that PC and reading the IBM/Microsoft Basic manual. Using the Spark for the last 2 days reminds me of that experience.

The recent *Your Brain on ChatGPT* paper seems cool. When a ugrad approaches me to do research, I still have them read a prefix of PLAI (1st ed.) and demonstrate that they understand it. I wonder what would happen if I asked them to self-study with an LLM exclusively. Has anyone tried this?

Now that I've written more Python than I care to admit, I'm getting tired of duplicating abstractions: one for sync code and another for async. Effect polymorphism wanted.

O1, R1, etc. are so good that we evaluate them on “PhD-level” benchmarks. But, these benchmarks are so hard that most people can’t even understand what they are testing. We’ve built a benchmark with problems that are hard to solve but easy to verify: for both humans and models.

It was fun to be a part of this. We analyze a dataset of student-LLM interactions on programming tasks and ask: what do students get wrong when prompting?

Counterintuitively, this shows the power of GC. IIRC I've heard of similar tricks used for high-performance OCaml at Jane Street.
