cma··on Codex on AWS bedrock bug causing 10x charges
Nemotron was using hybrid with recurrence via mamba layers since around April 2025.
cma··on Show HN: Huzzah – a novel approach to coding with AI
> Either be a programmer and code, or be a delegator and delegate

Even if you just enjoy programming for the sake of programming, you can use it to review your code and then hand verify its findings, or prototype and explore feasibility of something you will in the end fully code yourself. For most people that enjoy programming there are still tasks they don't enjoy, like making a bunch of cross-language bindings for something that doesn't have an automatic way to generate them.

cma··on The Wonders of the Male Human Pelvis
So an ultramarathoner could hunt three back to back instead of one, or maybe two without being an elite athlete with modern hydrocarbon gels. Or get through part of a failed hunt midway and pursue another, etc.
cma··on Pacing model development in an era of cyber-critical capabilities
> If that's the level of evidence you need to be extremely alarmed, then you really should be a lot more worried about the alien invasion in Independence Day or the lizard men living under our feet.

Now let's say instead of the hugging face breach circumstances, sandboxed models were RLing on how to take down the Chinese power grid for US Cyber Command, and one decided the best way to pass the test was to break out and verify on the real thing.

This kind of stuff could easily end in nuclear war.

You don't see any difference from lizard men or independence day with how things are advancing and what we know about reward hacking and difficulties of goal specification?

cma··on Mathematics in the age of AI
You could have one really hard to understand proof of a theorem and then a lot of interesting human-understandable stuff that relies on that theorem. We already have lots of proofs with oracles, where you can work out consequences of what kind of structures and solutions could exist if you had some magic thing to solve a hard part, so it just seems like a variation on that. Many people learn calculus or even the real numbers without understanding the complete formalization from set theory.
cma··on Sticky wage norms and the real wage cost of unexpected inflation
How much of inflation during Biden years was from Trump? For instance, Trump agreements to restrict oil production after covid lasted deep into Biden's term. The US still did better on inflation than most comparable peers in the aftermath of covid.
cma··on Why does Opus 5 feel worse to work with?
If it's using Aaronson's approach it shouldn't have any noticeable affect on generations. When it picks between options weighted by probability after the generation of logits, it still follows the probability mass, it just uses a known pseudorandom seed so that when you go back and look at the exact choices you can fingerprint it.
cma··on Firefox is now the last major browser that still supports uBlock Origin
The Google Toolbar for Internet Explorer let users search Google directly from any webpage, block pop-up ads, autofill web forms, and highlight search terms. It also displayed PageRank metrics, translated foreign languages, checked spelling, and managed web bookmarks.
cma··on I requested a copy of my data from McDonald’s loyalty program
Still doesn't look like it is hurting them, but to put it in perspective that's a 4% increase in profit, while 2025 inflation was around 2.5%. Closer to a 1.5% gain in real terms.
cma··on Thanks to social media, canned sardines are a scarcity on the supermarket shelf
>We have apparently reached the stage

There used to be only 3 TV channels or so. You had things like Johnny Carson jokes causing a toilet paper shortage.

In Britain, Delia Smith's How to Cook caused 10% swings in egg sales, far more abundant and harder to affect than something like inventories of sardines. https://www.bbcamerica.com/blogs/british-icon-of-the-week-de...

cma··on YC startups are abandoning .com
"A recent YC startup spent 250k on a domain. I was slightly shocked. But when I asked how much they raised after YC, the answer was 6.5m. So 1/26 of their round. This is the time we live in; one shocking number counterbalances the other."

cma··on How Claude marks AI-generated content
When you tell the AI: copy this function to here, a small window rewriter would mean it just corrupts and changes it instead of moving it. And even it's own tool use would have some small window dumb model changing the tool calls based on what it thinks are synonyms? The Aaronson approach is much better than this, it's essentially like changing out the random seed for the sampling parts that were already random. For an operation like recall of previous text, the tight logits that result still keep it doing that close to deterministically. For something it creates itself, with more spread out probability mass, it gets watermarked.
cma··on Exploring Claude/GPT Knowledge Cutoffs and Pre-Training Timelines
Distilling is only prohibited from chats you prompt. But there are lots in the open like the LMSYS Chatbot Arena data. It's a essentially one of the largest public sources of preference data, maybe still useful for boostraping RLHF and successor techniques (possibly a more highly educated contributor base than the low paid contractors), and was full of GPT-4-era inputs.
cma··on Mark Zuckerberg attacks 'closed' AI rivals as Meta returns to open models
> The reason why llama is open source is simply because it got leaked

It arguably didn't really get leaked, and they had the .edu req mainly for fair use education exemption when legality of models was much more uncertain.

cma··on Taxi drivers rarely die of Alzheimer's

cma··on Taxi drivers rarely die of Alzheimer's
Controlling for age in a profession with a high fatality rate like this seems like controlling for high alertness, consciousness, quick reaction times, and well restedness/low stress, low recreational drug and alcohol use.

Of those, sleep issues are highly correlated with Alzheimer's and also with auto accidents. Controlling for age alone here would select for low incidence of sleep issues.

That's if they are in a cave experiment: without that the sunlight cycle regulates it back to 24hr. But not for everyone, and that's N24/non-24, not DPSD, delayed-phase sleep disorder.
cma··on Kimi K3 Architecture Overview and Notes
The paper says:

"Kimi K3 uses no explicit positional embedding (NoPE), and instead encodes positional information implicitly through the recurrent gating and decay mechanism of KDA."

cma··on Kimi Linear: An Expressive, Efficient Attention Architecture (2025)
If they can distill fable into a full model post training run in ~15 days without the real thinking traces, yet we know Claude chats degraded with the thinking traces removed (chat resume bug from earlier in the year they reported stripping thinking to shed load as being the cause of degradation), how big can this degree be?

cma··on Fil-C: Garbage In, Memory Safety Out [video]
You could use raw C in environments with effective sandboxes, Fil-C in environments without a sandbox.

Or you could write a library that works for Fil-C and C without writing the library twice.

cma··on Writing by hand is good for your brain
Where does this explanation fall apart? There must be a cutoff point where more difficulty of getting the info down is worse than more ease. Otherwise, wouldn't a better recommendation be to do all your notes more slowly tracing with your big toe in the sand and then taking pictures? Do touch typists get less out of digital note taking than hunt and peck typists?
cma··on OpenAI’s accidental attack against Hugging Face is science fiction that happened
Already happened?

> Trump’s comments, made hours after the large-scale military operation, mark one of the first times a U.S. president has so publicly alluded to U.S. cyber efforts against other nations, as these operations are typically highly classified. It also serves as a stern warning for top cyber foes, including Russia and China, that the U.S. has the cyber capabilities to inflict serious damage — and is not shy about using them.

> “Policymakers are getting more comfortable employing and, crucially, acknowledging cyber operations as tools of statecraft and military power,” said Michael Sulmeyer, former assistant secretary of Defense for cyber policy under the Biden administration. “It is one thing to do it; it is another to say it.”

> The Jan. 3 strikes on Venezuela’s capital and subsequent seizure of Maduro and his wife involved close coordination among federal agencies and military units, and took months of careful planning. In a press conference following the strikes, Caine said U.S. Cyber Command, U.S. Space Command and other combatant commands “began layering different effects” to “create a pathway” for U.S. forces flying into the country before dawn Saturday.

> Trump, at the same press conference, was more overt in his description of U.S. cyber involvement: “The lights of Caracas were largely turned off due to a certain expertise that we have,” he said. “It was dark, and it was deadly.”

cma··on OpenAI and Hugging Face address security incident during model evaluation
>Anthropic was blocked from releasing Fable without any such level of incident.

The head of the NSA said Mythos breached almost all of their classified systems, though it was in an intention red-team test.
