It targets x86-64/ELF? I thought it would target `sh` to be portable?

That doesn't really explain anything biologically. Just vaguely says "potentially helps heal and protect"

What does the stem cell treatment help with beyond the existing fetal surgery? Since it's in addition to the usual surgical treatment

And I would further add: In addition to performance, Julia's language and semantics are much more ergonomic and natural for mathematical and algorithmic code. Even linear algebra in Python is syntactically painful. (Yes, they added the "@" operator for matmul, but this is still true).

I wonder if there's a law+econ analysis of comparing the current framework (regulations and upfront permitting) vs having the regulations but then enforcement via combination of randomized gov't inspections and private lawsuits. The motivation would be to allow things to move faster while also requiring the same degree of compliance, but without the massive red tape upfront with administrators having no real incentive to approve projects or move fast. One obvious downside is that it effectively creates an economic incentive to try and skirt the law and/or find loopholes, but that arguably exists to the same degree in the existing system.

lmao okay, touché. I did not realize it had servo as a dependency.

I don't think the point was to say "look, AI can just take care of writing a browser now". I think it was to show just how far the tools have come. It's not meant to be production quality, it's meant to be an impressive demo of the state of AI coding. Showing how far it can be taken without completely falling over.

EDIT: I retract my claim. I didn't realize this had servo as a dependency.

New comment by jey in "Why “negative vectors” can't delete data in FAISS – but weighted kernels can"

jey — Mon, 22 Dec 2025 00:23:50 +0000

That makes sense, but how do you efficiently evaluate the Gaussian kernel based approach (“operator-based data structures (OBDS)”)? Presumably you want to do it in a way that keeps a dynamically updating data structure instead of computing a low rank approximation to the kernel etc? In my understanding the upside of the kNN based approaches are fast querying and ability to dynamically insert additional vectors..?

> When I ran this program, I expected the `CF_OEMTEXT` string to have the byte 44, but it didn’t. It had the byte 90. We will start unraveling this mystery next time.

Whoa there exists something Raymond Chen didn’t know about Windows core APIs?

This seems to be incorporated into current LLM generations already -- when code execution is enabled both GPT-5.x and Claude 4.x automatically seem to execute Python code to help with reasoning steps.
