Both vehicles have comparable engines, but with the F-350 being much lighter it can achieve much higher accelerations and top speeds. In terms of dimensions they are quite similar as well.

The ChessPositionRanking project, with help from the Texel chess engine author, tries to prove random positions (that are not obviously illegal) legal by constructing a game ending in the position. If that fails it tries to prove the position illegal. This now works for over 99.99% of randomly generated positions, so one can feed the legal game record found for random legal positions.
Wow.

Given the tiny dimensions, and wide field, adding regular lenses over an array could create extreme wide field, like 160x160 degrees, for everyday phone cameras. Or very small 360x180 degree stand-alone cameras. AR glasses with a few cameras could operate with 360x160 degrees and be extremely situationally aware!

Another application would be small light field cameras. I don't know enough to judge if this is directly applicable, or adaptable to that. But it would be wonderful to finally have small cheap light field cameras. Both for post-focus adjustment and (better than stereo) 3D image sensing and scene reconstruction.
> Anthropic means "human," and if a company must remind me it is made of/by/for humans

Why do you think that that's their intended reading? I had assumed the name was implying "we're going to be an AGI company eventually; we want to make AI that acts like a human."

> if there's any "making" of the training content, Anthropic didn't do it

This is incorrect. First-gen LLM base models were made largely of raw Internet text corpus, but since then all the improvements have been from:

• careful training data curation, using data-science tools (or LLMs!) to scan the training-data corpus for various kinds of noise or bias, and prune it out — this is "making" in the sense of "making a cut of a movie";

• synthesis of training data using existing LLMs, with careful prompting, and non-ML pre/post-processing steps — this is "making" in the sense of "making a song on a synthesizer";

• Reinforcement Learning from Human Feedback (RLHF) — this is "making" in the sense of "noticing when the model is being dumb in practice" [from explicit feedback UX, async sentiment analysis of user responses in chat conversations, etc] and then converting those into weights on existing training data + additional synthesized "don't do this" training data.
> Funny this is cancel-worthy sometimes, and in other times it's treated as a quaint personality trait.

Yeah sometimes you see that in passing. Some famous people seem to get a pass especially if they are not polarizing nor brazen, as opposed to, say, someone like Donald Trump. But in the end, they hurt and abuse people all the same.

For example, almost every bio I've seen on YouTube about Richard Feynman treats his proclivity of banging his colleagues' wives as nothing more than some charming quirk or idiosyncrasy (usually to differentiate him from the bookish physicists of the time) at best, and a peccadillo at worst.

The worst description I've read yet of his behavior was summarized as: "he just loved women."

It's messed up.
Two movies, one screen.
The first large scale app I did we got offices in a building that used to have telco equipment in it. There wasn’t enough power or cooling to run about a rack worth of equipment split across several. It basically had a mini-split for AC. We had to bring in new wiring and run a glycol line to a condenser on the roof, and the smallest unit we were willing to pay for was too big so we had to knock out a wall to tack a reasonable sized office onto the end to get the volume large enough. So much wasted space for the amount of equipment in there.
Linear regression also learns to model data to some degree. Using the term “world model” that expansively is intentionally misleading.

Besides that and the big red flag of not directly analyzing the performance of the predicted board state I also said training a neural network to return a specific result is fishy, but that is a more minor point than the other two.

Humans with correct models may nevertheless make errors in rule applications. Machines are good at applying rules, so when they fail to apply rules correctly, it means they have incorrect, incomplete, or totally absent models.

Without using a word like “understands” it seems clear that the same apparent mistake has different causes.. and model errors are very different from model-application errors. In a math or physics class this is roughly the difference between carry-the-one arithmetic errors vs using an equation from a completely wrong domain. The word “understands” is loaded in discussion of LLMs, but everyone knows which mistake is going to get partial credit vs zero credit on an exam.

This is one of those things where specs are still hard to parse.

It is considered invalid syntax to lead with a dot by the rules. But it also must be ignored if present. Its lacking a “MUST NOT” because the spec is defining valid syntax, while also defining behavior for back compat.

It would break too many things to throw here or serialize while ignoring the leading dot. Leading dots are discouraged, but shouldnt break anyone following the spec. Maybe a warn log in dev mode if serializing a domain with dot, to try and educate users. Dunno its worth it though.

The point of jshttp IMO is to smooth over these kinds of nuances from spec updates. So devs can get output which is valid in as many browsers as possible without sacrificing functionality or time studying the tomes.

Plastics are mostly carbon and hydrogen atoms, neither of which are even remotely limiting factors because autotrophs at the bottom of the food chain produce plenty of both from water and carbon dioxide.

Agricultural runoff is mostly nitrogen and phosphorus, which are limiting factors (hence why we have to supplement them in agriculture).
I would be interested to know the cost of more sustainable packaging at economies of scale. Almost all plastic-based packaging emerged after 1950, yet even before then, there was a need to package mass consumer goods on a large scale.

I also believe plastic and PFAS coatings are used in packaging largely because they are assumed to be the only suitable materials. However, in earlier times, there were many clever and cost-effective solutions.

Key features:

Speed: Backed by Cloudflare with a fully static site, making it faster than Google Drive for loading resources.

Organization: Categorized sheets for easy browsing (Anime, Creatures, Styles, Time Periods, Techniques, etc.).

Free to Use: No barriers or paywalls—just a simple site for the community.

I’d love your feedback on the site! Whether you're an artist, AI enthusiast, or just curious, I hope it’s helpful to you.

Check it out at FindArt.Pro.

Again, food addiction and satiety is a different question than if CICO works. If you can't stop eating and cram too many calories because you eat too many... burgers and potato chips or whatever, that has nothing to do with if CICO works. I have yet to see evidence that shows that caloric restriction if properly, truly controlled, does not result in weight loss for the vast, vast majority of obese individuals. People are notoriously bad at estimating calories and knowing how much they eat, so any study that is self-reported is inherently going to be problematic.

Should we do more research to find if anything anything specific that may be causing overeating or food non-satiety? Sure. Is the answer likely to be something that is essentially 'tastier food is easier to overeat, and tastier food is much more available than it used to be'? I suspect that is the likely conclusion.

I think GLP1 agonists are a great tool to be used to create that so-called 'willpower' to stop overeating (or, an easy way to reduce food noise, whatever you want to call it). The next step is figuring out how, as a society, we make it easier for folks to make that lifestyle change without a constant stream of 'willpower drugs' for the rest of their life.
Show HN: Optiwing – Keyword Grouping and Other PAYG SEO Tools
What's up Hacker News, I built a keyword grouping tool as a developer managing my own websites' SEO, I found myself frustrated with expensive subscription based SEO tools that had lots of unnecessary features for my needs. So I made a simple tool for myself that grew into it's own product. Optiwing has tools for Keyword discovery, grouping, content briefing, SERP checking and SERP comparison.
What I did different: Pay-as-you-go pricing with no subscriptions, Simple integrated workflow from keyword research to grouping, to content briefing, Large scale keyword grouping to identify which keywords can be targeted with a single piece of content using live Google search data for accuracy.
I'd love feedback, especially from others managing their own SEO who find existing tools too expensive for their needs. Cheers

It's also that running a benchmark by wrapping it in a shell script and invoking "date" externally adds a constant offset to all timings. It's negligible if the benchmark itself takes long enough, but not when you go down to 0.25s or even 0.06s.
It's a good point.

But this math analogy is not quite appropriate: there's abstract math and arithmetic. A good math practitioner (LLM or human) can be bad at arithmetic, yet good at abstract reasoning. The later doesn't (necessarily) requires the former.

In chess, I don't think that you can build a good strategy if it relies on illegal moves, because tactics and strategies are tied.
> Computationally it's trivial to detect illegal moves

You're strictly correct, but the rules for chess are infamously hard to implement (as anyone who's tried to write a chess program will know), leading to minor bugs in a lot of chess programs.

For example, there's this old myth about vertical castling being allowed due to ambiguity in the ruleset: https://www.futilitycloset.com/2009/12/11/outside-the-box/
(Probably not historically accurate).

If you move beyond legal positions into who wins when one side flags, the rules state that the other side should be awarded a victory if checkmate was possible with any legal sequence of moves.
This is so hard to check that no chess program tries to implement it, instead using simpler rules to achieve a very similar but slightly more conservative result.
Well, you’re shifting the goal posts. The original scenario was simply uploading files to the application folder on production servers and reloading the page.

Of course there are viable strategies to avoid this specific issue, but they all introduce complexity of themselves.
Extremely tangential, but how to chess engines do when playing from illegal board states? Could the LLM have a chance of competing with a real chess engine from there?

Understanding is a funny concept to try to apply to computer programs anyway. But playing from an illegal state seems (to me at least) to indicate something interesting about the ability to comprehend the general idea of chess.

The discussion in this thread is amazing. People, even renowned experts in their field make mistakes, a lot of mistakes, sometimes very costly and very obvious in retrospect. In their craft.

Yet when LLM, trained on corpus of human stupidity, no less, make illegal moves in chess, our brain immediately goes: I don't make illegal moves in chess, how can computer play chess if it does?

Perfect examples of metacognitive bias and general attribution error at least.
So I think that the idea of “you cannot maneuver a large org without a calendar” is going back to tommdemarco and risk management as the soul of project mgmt

If you run a company and ask me for an estimate on when software will be ready because the rest of the company depends on it, then what you are doing is making a huge bet on the software team delivering to time and quality (and cost!). Now that’s just hoping.

There is plenty to do to fix it (reduce scope, improve team dynamics and psychological safety, dual delivery teams etc). But in the end it’s a bet, a guess.

Now perhaps there are better ways. I would suggest we look twice at using calendars and deadlines as ways of acgieveing co-ordination - software is waaay better at co-ordination than people and calendars are.

As an American, WhatsApp seemed like an odd fit with Facebook but I also travel internationally a great deal. Almost every single interaction I have while traveling anywhere that isn't Europe and North America, from coordinating airport pickups with drivers to requesting fresh towels from hotel staff, occurs via WhatsApp nowadays.

It's actually really nice. I booked a dive in Belize earlier this year and all I did was scan a QR code of an ad I saw in the hotel, send them a screenshot of my NAUI app, sign a waiver from a link they sent me, then they sent a payment link, google maps directions, and instantly responded to my question when I couldn't find the right dock. All of this occurred on WhatsApp in the span of like 90 minutes.
