Apparently this implementation beats ripgrep 2-4x in every benchmark

I saw a joke tweet saying "grep is the most important agent tool" so I decided to benchmaxx a faster grep tool in Rust.

It worked lololol

fuck it, feed the paper to Codex/Opus and let them figure out how to implement it

Introducing GPT-5.4 Introducing GPT-5.4, OpenAI’s most most capable and efficient frontier model for professional work, with state-of-the-art coding, computer use, tool search, and 1M-token context.

god damn it let me relax for one day please openai.com/index/introd...

Everytime GPL license drama pops up I am reminded why I exclusively open-source using MIT.

I really wish Claude Code had native queueing.

now this is software development

"I will be more virgin."

Yeah this is exactly the thing. Increasingly you are telling people to not believe their lying eyes when you tell them LLMs are useless. Their actual lives will directly contradict this. They will likely discount most other unrelated things you say as a result. This can’t become a left/lib dogma.

Explain the benefits of Rust's memory safety as if I was a nontechnical teenager. --- Okay, imagine your computer's memory is like a giant wall of lockers in a school hallway. Every program running on your computer needs to use some of those lockers — storing numbers, text, images, whatever it's working with. The problem is, most programming languages basically hand you the keys and say "good luck." You might accidentally open someone else's locker, forget to lock yours when you're done, or even try to use a locker that's already been emptied out. These mistakes cause crashes, security holes, and weird bugs that are really hard to track down. Rust is different. It acts like a really strict but fair hall monitor. Before your program even runs, Rust checks your code and says things like: "Hey, you're done with that locker — I'm locking it up for you." You don't have to remember to clean up after yourself. Rust handles it automatically, so you never leave a locker hanging open and wasting space (this is called a "memory leak" in programming). "Hold on, two people can't write in the same locker at the same time." If one part of your program is changing some data, Rust makes sure no other part can mess with it at the same time. This prevents a whole category of nasty, unpredictable bugs. "That locker is empty — you can't read from it." Some languages let you peek into a locker that's already been cleared out, and you'd get garbage data or a crash. Rust simply won't let you do that.

Opus 4.6 is not good at metaphors.

just vibecoded a sick-ass confusion matrix

update: annoyed it enough

Here's Opus's optimization results from that prompt, which naturally raised an eyebrow. I tested out the app afterwards and it turned out Opus disabled most of the physics.

Asked Claude Opus 4.6 to make my terminal ball physics app faster and it decided "the rapier 2D physics crate is too slow, I'm implementing my own physics solver from scratch dammit"

It then gave up when it realized how much work that it would be.

I suspect I will be banned from /r/rust.

The biggest mystery of Hacker News I've never solved is how submissions that fell off the front page still get upvotes.

Katy Perry signs up for a Claude pro plan

Sparse arrays are scary

there's a nonzero chance I butchered the Rust technical explanations

An AI agent coding skeptic tries AI agent coding, in excessive detail No vagueposting here, just look at the Estimated Read Time.

New blog post up: the culmination of my past few months working with agents Opus 4.5 and beyond, and the *many* things I learned. Also, the discovery of an optimization trick with promise.

As a bonus: this post will make Rust engineers very mad. minimaxir.com/2026/02/ai-a...

Tbh Bluesky might be more normal than the other place about AI at this point, as it’s increasingly divided into machine cultists or screaming butlerian jihadists.

tl;dr it is exactly between Nano Banana and Nano Banana Pro so don't have to write a blog post about it, yay.

ffffffffff

I suspect results will be similar to Nano Banana Pro (since Gemini 3 text encoder) but cheaper so likely not enough material for another blog post

if Google drops Nano Banana 2 tomorrow i am going to be very annoyed, I wanted it to be a quiet day for once

the comments at the bottom are quintessential "no fun allowed" news.ycombinator.com/item?id=4713...

(evil is not statistically significant)

I haven't seen anyone talk about Sonnet 4.6 for agent coding and it's, uh, not good.

they call him p-man

what the fuck?
