ncruces··on Gemini 4 Argon
Because (maybe particularly) at 1e100 scale, having a super intelligent butler that does whatever everyone asks of it can easily get you to hundreds of thousands of daily PRs merged to the monorepo, but won't necessarily help coordinate efforts, and may actually cause certain projects to collapse under their own weight.
ncruces··on Gemini 4 Argon
Because none of the people who can use it (have been and will be using it) can talk about it if it hasn't been announced. NDAs and stuff.
ncruces··on Sonnet 5.5
Not true. Claude is laser focused at finding the next load bearing thing. /s
ncruces··on Nissan's third generation e-POWER powertrain
And the Toyota has planetary gears.

Both offer direct, mechanical engagement that avoids the continuous friction slip of a wet clutch.

Which was the point.

ncruces··on Nissan's third generation e-POWER powertrain
Renault's version doesn't have a clutch either.
ncruces··on Lunar Terminator Paradox
In that time lapse, when the moon is visible, the illuminated portion is always facing “down,” i.e. the horizon?
ncruces··on When did Google get so weird?
In TFA the chatbot got confused, and the author never decided to correct it with "no I'm trying to find an old tweet about NBA Dario" which a normie would do, and be satisfied with the result.
ncruces··on Go Concurrency Distilled
You can try this yourself: GODEBUG=asyncpreemptoff=1

Also platforms like Wasm still do Mx1 scheduling without async preemption, where Gosched is required at places.

E.g.: my "transpiled" SQLite driver takes special care to make sure long running SQL queries (and the busy handler) can be canceled with contexts even on platforms without async preemption.

ncruces··on U.S. appeals court upholds designation of Anthropic as supply chain risk
The DoD can require contractors not use Claude to do whatever they're being contracted to do.

It doesn't need to say if you do any business with Anthropic (for other customers, internal tools or processes), you lose all your contracts with us.

ncruces··on U.S. appeals court upholds designation of Anthropic as supply chain risk
The point is: using Claude to design a website, do accounting, run a marketing campaign, is not a supply chain risk for the DoD, but taken literally and given the scale of the DoD "no DoD supplier can use Claude for anything" clearly is punitive.
ncruces··on U.S. appeals court upholds designation of Anthropic as supply chain risk
And thus, every supplier of the DoD is prohibited from asking Claude to tweak the CSS on their website.
ncruces··on Jev Based Code Review
Doing stuff at the 1e100.net scale.
ncruces··on Jev Based Code Review
Welcome to 2026.

My dev branch got broken when I rebased to main after a week of drift.

I had to bisect over around a million commits to the monorepo to find the culprit.

ncruces··on Python Workers are now generally available
The Go compiler supports wasm/js (browser) and wasm/wasip1 (WASI) out-of-the-box.
ncruces··on AX – Google’s Open Agentic Orchestrator
Tell us more about your grandma.
ncruces··on Comparison of Malloc() Algorithms
Thanks for the link.

Article makes it look like nothing happened in the embed/low-memory/single-threaded malloc space in decades since Doug Lea's malloc.

I just implemented TLSF for my minimal Wasm libc: fragmentation is just as good, performance is a lot more consistent (and on average better), for a significant reduction in code size.

ncruces··on The Beauty of Roundabouts
> In those cases, the bulk of traffic all needs to slow down, downshift, …

You know that's like, the entire point of roundabouts: force traffic to slow down.

ncruces··on Why I'm still bearish on LLMs after Navier-Stokes
But we are. The models can't even follow the rules: they try illegal moves all the time.
ncruces··on Astra and Fable still hack on simple variants of alignment evals from 2025
The problem then, is giving them (humans, AIs) unchecked power.
ncruces··on Base84 deserves a place in file names
I think the idea is that it being case preserving is sufficient to allow decrypting the filenames.

And I guess it relies on the 31 (32?) bit blocks, to make colisions unlikely for short filenames.

ncruces··on Aligned to whom?
> … trivial. Just as raising a child is not to break the law.

Trivial?

ncruces··on We must pace the frontier
That doesn't really apply to the people running the AI, which gave it the capability to commit crimes.

They don't get to act like victims, asking for law enforcement.

ncruces··on Performance of WebAssembly Runtimes in 2026
Thanks for the kind words!

Added you to my users page a couple days ago, hope you don't mind: https://github.com/ncruces/wasm2go/blob/main/USERS.md

ncruces··on Eating Fruit Skins
You can make curry with them (either just the peels, or whole unripe bananas).
ncruces··on Performance of WebAssembly Runtimes in 2026
Curious where my wasm2go would stand compared to wazero. I should test it myself. :)

ncruces··on Navier-Stokes Announcement
Perelman posted to arXiv in 2002/3.

The prize was offered to him in 2010, after multiple others had digested his work and published elsewhere.

ncruces··on Navier-Stokes – Tristan Buckmaster [pdf]
I read that as “the model didn't look up user data” as part of a “tool call,” i.e. they don't have an internal tool that loads user data (chats, sessions, attachments) for their internal models to read online while working.

Or (likely) they do have it, but the model didn't use it (unless it's so powerful it escaped that guardrail, wouldn't that be ironic?)

They declined to answer about anonymized aggregated user data being used for training. And even then, they may weasel out that they don't train on your “input” words, but that it's fair game go train on their “output” to your words.

ncruces··on Balrogg: Demonically compacting (up to 15%) lossless Vorbis/Opus recompressor
Kinda like what Dropbox Lepton did for JPEG back then.

ncruces··on Global warming will exceed 1.5-degree limit, UN says
> Back to reality, west Europe is firmly a social democracy where states impose behavior through law, regulation, and policy, which is topped by a federal system that coordinates policies.

And yet, air travel continues to grow (after a small hiatus due to COVID) and state and EU money will be dumped into a new airport near me, to support more than doubling current capacity, much further away from the city (adding tens of millions of car trips to and from the airport).

I'm simply the looney for not taking the kids on low cost European city escapes.

It starts from the “bottom”: people will talk about it, but will pretty much continue to do whatever the fuck they can afford to do. And Europeans, like Americans, can simply afford to much, while harping about what will happen to the world once the BRICS can afford the same.

ncruces··on The largest electric aircraft just flew [video]
I never said anything about green. They don't have oil, they want to be less reliant on oil. Electricity allows them to adapt the mix in a way petrol doesn't.
