..A small thing, but it won't compile the RISCV version of hello.c if the source isn't installed on the machine it's running on.

It is standing on the shoulders of giants (all of the compilers of the past, built into it's training data... and the recent learnings about getting these agents to break up tasks) to get itself going. Still fairly impressive.

On a side-quest, I wonder where Anthropic is getting there power from. The whole energy debacle in the US at the moment probably means it made some CO2 in the process. Would be hard to avoid?

Pointing to the profile leads someone on the path of understanding why to trust tptacek on security issues. Pointing to his points on HN explains why lots of users here already know that he's credible in this area and will recognize his username and upvote his comments on this topic and know better than to blindly accuse him of being a just a random person on the internet.

The problematic, ignorant comment that has been flagged asserted that what tptacek says "means nothing to anybody else", which is a very wrong statement about his role in the HN community.

Hi HN,

I built a tool that transforms flat-lay or mannequin product photos into realistic images with human models wearing them.

What it does:

Upload your clothing photo → AI generates a photorealistic image of someone wearing it. Takes about 10 seconds.

Key feature - Model Display control:

You choose who wears your product:
- Gender (male/female)
- Pose (front, side, back, three-quarter, dynamic)
- Body type (slim, regular, athletic, plus size)

This means one product photo can become an entire diverse catalog.

Who it's for:

- Dropshippers who only have supplier photos
- Small brands who can't afford model shoots
- Marketplaces sellers wanting consistent product imagery
- Anyone testing product ideas before manufacturing

Pricing:

Free tier available. Paid plans start cheap.

Try it: https://createvision.ai/ai-product-mockup

Happy to answer questions about the tech or take feature requests.

As a regular human who plays games and doesn't know about chip architectures, one woud probably lump the wii and the switch closer together than the game cube based on the modes in which one can interact with the systems.

Wii is a game cube with a funny controller. Or, wii is a tv-only olde switch.

I appreciate that it has its own name due to being a transitional experience.

That would indeed be the case if one has never learned the stuff. And I am all in for not using AI/LLM for homework/assignments. I don't know about others, but when I was in school, they didn't let us use calculators in exams.

Today, I know very well how to multiply 98123948 and 109823593 by hand. That doesn't mean I will do it by hand if I have a calculator handy.

Also, ancient scholars, most notably Socrates via Plato, opposed writing because they believed it would weaken human memory, create false wisdom, and stifle interactive dialogue. But hey, turns out you learn better if you write and practice.

I'd argue that the moment one cares about accuracy and blast radius, one would natural want to reduce error compounding from a combination of LLM calls (non deterministic) and it's very natural to defer to well tested determinist tools.

Do one thing and do it well building blocks and the LLM acts a translation layer with reasoning and routing capabilities. Doesn't matter if it's one or an orchestrated swarm of agents.

No, the shitty regime has stolen, squandered, and prevented the vast majority of Cuba's (potential) income.

They've received free oil from Venezuela, Mexico, and Russia for decades. This whole crisis is because the country is horribly mismanaged and the free ride is over.

Most countries have to purchase their oil at market prices. Cuba has been spared that burden yet is still worse off than the average country.

IIRC both Russia and China have demanded economic reforms which are not forthcoming. The Chinese aren't stupid and they don't seem too interested in pissing their money away indefinitely on a 'partner' who ignores them.

I don't mean this as a knock on you, but your comment is a bit funny to me because it has very little to do with "modern" databases.

What you're describing would probably have been equally possible with Postgres from 20 years ago, running on an average desktop PC from 20 years ago. (Or maybe even with SQLite from 20 years ago, for that matter.)

Don't get me wrong, Postgres has gotten a lot better since 2006. But most of the improvements have been in terms of more advanced query functionality, or optimizations for those advanced queries, or administration/operational features (e.g. replication, backups, security).
Ask HN: Anyone Seeing YT ads related to chats on ChatGPT?
by guhsnamih | 2026-02-06 00:57:00+00:00
I have encountered ads on YouTube that closely match what I think I am only asking on ChatGPT. e.g. just today I asked ChatGPT if I am speaking too much and an hr or so later I see a sponsored video on YouTube about exposing your weakness by speaking too much. Is there a direct link between the two, am I hallucinating or it's a divine intervention? I am on FF on Linux and I have ChatGPT installed on my Android phone. If that makes any difference.

Thanks

It’s a simple compiler optimization over bayesian statistics. It’s masters-level stuff at best, given that I’m on it instead of some expert. The codebase is mixed python and rust, neither of which are uncommon.

The issues I ran into are primarily “tail-chasing” ones - it gets into some attractor that doesn’t suit the test case and fails to find its way out. I re-benchmark every few months, but so far none of the frontier models have been able to make changes that have solved the issue without bloating the codebase and failing the perf tests.

It’s fine for some boilerplate dedup or spinning up some web api or whatever, but it’s still not suitable for serious work.

Overwhelmingly, there's no such thing as a zero crossing. Your closest real world case is a point in time (between samples) where the previous sample is positive and next one is negative (or vice versa). However, by truncating the next sample to zero, you create distortion (and if the absolute value of the preceding sample is large, very significant distortion.

Zero crossings were an early myth in digital audio promulgated by people who didn't know enough.

Fades are always the best solution in terms of limiting distortion (though even then, they can fail in pathological situations).

Clean-room design is extremely specific. Anyone who has so much as glanced at Windows source code[1] (or even ReactOS code![2]) is permanently banned from contributing to WINE.

This is 100% unambiguously not clean-room unless they can somehow prove it was never trained on any C compiler code (which they can't, because it most certainly was).

Thanks for elaborating. So what is the empirically-testable assertion behind this… that an LLM cannot create a (sufficiently complex) system without examples of the source code of similar systems in its training set? That seems empirically testable, although not for compilers without training a whole new model that excludes compiler source code from training. But what other kind of system would count for you?

I have wanted to hold back from answering comments that ask for proof of real work/productivity gains because everyone works differently, has different skill levels and frankly not everyone is working on world changing stuff. I really liked a comment someone made a few of these posts ago, these models are amazing! amazing! if you don't actually need them, but if you actually do need them, you are going to find yourself in a world of hurt. I cannot agree more, I (believe) I am a good software engineer, I have developed some interesting pieces of software over the decades and usually when I got passionate about a project, I could do really interesting things within weeks, sometimes months. I will say this, I am working on some really cool stuff, stuff I cannot tell you about, or else. And my velocity is now days for what used to take months and hours for what used to take weeks. I still review everything, I understand all the gotchas of distributed systems, performance, latency/throughput, C, java, SQL, data and infra costs, I get all of it so I am able to catch these mofos when they are about to stab me in the back but man! my productivity is through the roof. And I am loving it. Just so I can avoid saying I cannot tell you I am working on, I will start something that I can share soon (as soon as decades of pent up work is done, its probably less than a few months away!). Take it with a grain of salt, and know this, these things are not your friends, they WILL stab you in the back when you least expect them, cut a corner, take a short cut, so you have to be the PHB (dilbert reference!) with actual experience to catch them slacking. Good luck.

I'm Josh, founder of Synth. We've been working on coding agent optimization with method like GEPA and MIPRO (the latter of which, I helped to originally develop), agent evaluation via methods like RLMs, and large scale deployment for training and inference. We've also worked on patterns for memory, processing live context, and managing agent actions, combining it all in a single stack called Horizons. With the release of OpenAI's Frontier and the consumer excitement around OpenClaw, we think the timing is right to release a v0.

It integrates with our sdk for evaluation and optimization but also comes batteries-included with self-hosted implementations. We think Horizons will make building agent-based products a lot easier and help builders focus on their proprietary data, context, and algorithms

I think it's interesting that they dropped the date from the API model name, and it's just called "claude-opus-4-6", vs the previous was "claude-opus-4-5-20251101". This isn't an alias like "claude-opus-4-5" was, it's the actual model name. I think this means they're comfortable with bumping the version number if they want to release a revision.

> What is TrumpRx?

> TrumpRx is a website that lists discounted drug prices from manufacturers that have agreed to Most Favored Nation (MFN) pricing. Americans can use TrumpRx to purchase drugs in cash (outside of their insurance). These drugs can be obtained at participating pharmacies using coupon cards displayed on TrumpRx or directly through manufacturers' websites.

BTW - this is literally how drug prices already worked. Drug companies provided insurance companies with marked up prices, but if you reached out to the drug company directly they gave you the same "final" prices that the insurance companies more or less received.

(Or some drugs play it both ways - for example Humira will literally pay off whatever your drug company doesn't cover)

Instead of fixing or ending this shady pricing practice, they just stood up a website to claim the fake "savings" for their own credit.

>The best way to search I think is a coding agent with grep and file system access, and that is because the agent can adapt and explore instead of one shotting it.

I tried the knowledge base feature in Claude web recently, uploaded a long textbook.

The indexer crashed and the book never fully indexed, but Claude had access to some kind of VM and reverse engineered the (automatically converted) book's fileformat and used shell tools to search it for the answers to my questions.

(Again, this was the web version of Claude, not Claude Code on my computer!)

I thought that was really neat, a little silly, and a little scary.

As a rule of thumb, most people who say things like "X is useless and a waste" or "Y is revolutionary and is going to change everything by tomorrow" when the dust hasn't even begun to settle are stupid, overly-excitable, too biased towards negative outlooks, and/or trying to sell you something.

Sometimes they have some good points so you should listen to what they have to say. But that doesn't mean you have to get absorbed into their world view. Just integrate what you see as useful from your current POV and move on.

The idea that a single CCTV feed is at all comparable to aggregatable Flock data is a deeply unserious position. I’m not clear why you think you can pretend that single cameras and a network of cameras are either similar or comparable, in this context? Or why traffic cameras aren’t essentially identical, if they’re used identically?

I’d like to give the benefit of the doubt, but it feels very sea-liony and intentionally disingenuous.

Hah. These are the same weirdos who spoke like this to Jobs: https://www.youtube.com/watch?v=oeqPrUmVz-o

There's a big difference between geeks and hippies. Too many of the former here and not enough of the latter here - people who can understand other people, culture etc and then think about how technology can fit into ones life.
by nomel | 2026-02-06 01:04:10+00:00
Yes, but you have the problem that a good portion of that is going to be AI generated.

But, I naively assume most orgs would opt out. I know some orgs have a proxy in place that will prevent certain proprietary code from passing through!

This makes me curious if, in the allow case, Anthropic is recording generated output, to maybe down-weight it if it's seen in the training data (or something similar)?

If the end user is not crafting skills “correctly” and they aren’t getting picked up as a result, then that tells me the ecosystem around skills detection and the documentation surrounding it needs work. Ultimately the interface presented to the end user is “put these skills in, Claude will look and decide if it needs them”, but no additional tooling warning or guidance if it doesn’t work as expected. It’s just silent failure. Pretty garbage UX
by nacozarina | 2026-02-06 01:04:30+00:00
None of the alternatives have stability. What was exemplary & idiomatic rust pre-pandemic would be churlish & rejected now and the toolchain use would be different anyway.

Carpenters, plumbers, masons & electricians work on houses 3-300 yrs old, navigate the range of legacy styles & tech they encounter, and predictably get good outcomes.

Only C has, yet, given use that level of serviceability. C99, baby, why pay more?

When there’s an alternative that can compete with that sort of real-world durability, C will get displaced.

As kind of a knot guy, unlike other commenters this is my #1 favorite knot site.

Other sites with animated 3D models might be useful for visualizing the topology of knots, or something. But for actually tying the knots I find this site and its curated photos much more practically useful. The fact that it's not literally animated is a feature; it shows the key points rather than every detail.

And the photos are just clearer and better than any other resource. (If you look closely you'll see a lot of editing work has been done on them like to minimize the diff between consecutive photos.)

Only downside is that I wish it had more minor knots!
by smcleod | 2026-02-06 01:04:51+00:00
Yeah I think it's either a billing bug, or some sort of inbuilt background sub-agent loop gone wild inside Claude Code, if you have a look at recent issues on the Github relating to 'limits', 'usage', 'tokens' you'll see a lot of discussion about it: https://github.com/anthropics/claude-code/issues?q=sort%3Aup...

Because they'll turn on each other.

In an authoritarian regime, it's all competition, no co-operation. Whoever the big dog is gets to say what happens, right up until a bunch of the little dogs drag him down and then fight each other to replace him. If he's lucky and skillful he'll have worked this out and kept the little dogs at each other's throats so they don't gang up on him.

The whole operation of government becomes about "who's the boss?" and the boss gets to run the government to favour himself and his cronies, acquiring more power and wealth.

Any pause to consider the ordinary folks caught up in this is a weakness, that will be taken advantage of by the other wannabe bosses.

It's not a utopia for any of them because of the constant paranoia and fighting. Try to rest on your laurels and enjoy the spoils of what you got for a second, and boom; you get thrown out of a window.

The article actually points out a number of things only added after 2006, such as full-text search, JSONB, etc. Twenty years ago your full-text search option is just LIKE '%keyword%'. And it would be both slower than less effective than real full-text search. It clearly wasn’t “sub-100ms queries for virtually anything you want” like GP said.

Atlas Shrugged (and the fountainhead) is like a superhero comic book where the almighty good guys fight the flat, faceless "bad guys" with pure and fully justified moral righteousness. The "bad guys" are a slobbering caricature of a boogeyman that everyone can easily despise - wanting to do nothing except take from others like a bridge troll or a grey goo disaster scenario.

Nothing wrong with that I suppose but the second someone implies it has something to say about real life capitalists or social welfare or anything else then it gets weird; that makes as much sense as any of the marvel movies helping you decide how to vote for exactly the same reason.

I expect it's for this reason you're being downvoted - these books are often used as a motte and baily to imply something about real life (or often to ironically excuse their own selfish/bad behavior) and they just don't hold up for that in my opinion.

100% of the team (14 engineers) is using Claude Code for everything. Anecdotally it feels like velocity is 10%-20% faster. Objectively I have no idea if velocity is faster – because management is inept and does not actually track this. The most noticeable thing is test coverage has greatly improved. Every PR ships with lots of tests, whereas before we used AI we had little to no test coverage since it was just too time consuming.
by tempestn | 2026-02-06 01:07:17+00:00
It really depends on your use case, doesn't it? I'd say, just use Postgres... until you have a reason not to. We used finally switched to Elasticsearch to power user search queries of our vehicle listings a few years ago, and found its speed, capabilities, and simplicity all significant improvements compared to the MariaDB-based search we'd been using previously. (Postgres's search features are likely better than MariaDB's, but I expect the comparison holds.) But that's the core of our product, and while not giant, our scale is significant. If you're just doing some basic search, you don't need it. (We managed for many years just fine without.)

I've never really regretted waiting to move to a new tool, if we already had something that works. Usually by doing so you can wait for the fads to die down and for something to become the de facto standard, which tends to save a lot of time and effort. But sometimes you can in fact get value out of a specialized tool, and then you might as well use it.

Huh, apparently this is controversial, based on the score ping-ponging up and down! I'm not really sure why though. Is it because of the reference to MariaDB?
by riazrizvi | 2026-02-06 01:09:03+00:00
Relevant because it's universal human nature, to only have domain over a narrow context in life, and assert what's good/bad based on that limited view with others who occupy a different one. We use justifications which make sense to us that others rightly disagree with. It's not left politics, it's not right politics, it's not just politics, it's everything. Anyone who asserts they are beyond it are full of it.

This turned very argumentative very fast. I had thought we were having an amicable discussion about the semantics of real estate titles.

I mentioned my experience with a state tax authority because it is direct personal experience about this very topic. I don't know why you turned that into being about the IRS, and are now even seemingly rejecting the state tax authority "being involved". The date of the transfer was directly relevant to my disagreement with the state tax authority, and they didn't question that date being the deed date even though the recording happened some time later. Either believe me or not, I don't care.

> Evidently your experiences with government bureaucracies have been very, very different from mine.

Sure? I'm not saying they were a some pleasant, responsive, quick, and casual experience - rather much less bad than I was expecting. And dealing with some corporate bureaucracies has been much worse, with constant transferring and calling back every week to check on status and make sure a ticket didn't get stuck and timeout, etc.

Exploitation is to make the exploitor rich, not to make the exploitee rich.

But from what I understand Mexico could be a bit better off then it was decades ago.

But looking at history, the US took big chunks of land from Mexico in the 1800s. The resources from that land made the US what it is now. So in another time, Mexico and the US could have been completely different if that did not happen.
by rented_mule | 2026-02-06 01:10:16+00:00
A fascinating takeaway from that video for me... If you take the US land that is dedicated to growing corn for ethanol that is put in gasoline, and replace all the corn on that land with solar panels, how much energy would it produce? Twice today's total electrical generation in the US, from all sources. And that's in the corn belt, which is far from ideal for solar. It would be billions of panels, but it's a pretty interesting perspective on the questions about the land use requirements of solar.
