This still looks like immigration theatre to me. They’re pulling people off the streets without a lot of concern as to their specific status. However, I’m unaware of any action against the people and companies who hire and profit from illegals. They’re the big offenders, as without their cash there’d be less reason to stay. But, if they’re being left along because “they’ve checked their workers”, then I guess they’re all legal and ICE is grabbing them in error. Customers aren’t narc’ing them out, just pocketing the reduced charges so I guess they’re complicit as well?
Ask HN: Are we pretending RAG is ready, when it's barely out of demo phase?

Been watching the RAG (Retrieval-Augmented Generation) wave crash into production for over a year now.

But something keeps bugging me: Most setups still feel like glorified notebooks stitched together with hope and vector search.

Yeah, it "works" — until you actually need it to. Suddenly: irrelevant chunks, hallucinations, shallow query rewriting, no memory loop, and a retrieval stack that breaks if you breathe on it wrong.

We’ve got: • pipelines that don’t align with what users actually want to ask, • retrieval that acts more like a search engine than a reasoning aid, • brittle evals (because "correct context" ≠ "correct answer"), • and no one’s sure where grounding ends and illusion begins.

Sure, you can make it work — if you’re okay duct-taping every component and babysitting the system 24/7.

So I gotta ask: Is RAG just stuck in prototype land pretending to be production? Or has someone here actually built a setup that survives user chaos and edge cases?

Would love to hear what’s worked, what hasn't, and what you had to throw away.

Not pushing anything, just been knee-deep in this and looking to sanity check with folks who’ve actually shipped stuff.

Skepticism is an understatement. There are tons of issues with this paper. Why are they comparing results of their expert model that was trained from scratch on a single task to general purpose reasoning models? It is well established in the literature that you can still beat general purpose LLMs in narrow domain tasks with specially trained, small models. The only comparison that would have made sense is one to vanilla transformers using the same nr of parameters and trained on the same input-output dataset. But the paper shows no such comparison. In fact, I would be surprised if it was significantly better, because such architecture improvements are usually very modest or not applicable in general. And insinuating that this is some significant development to improve general purpose AI by throwing in ARC is just straight up dishonest. I could probably cook up a neural net in pytorch in a few minutes that beats a hand-crafted single task that o3 can't solve in an hour. That doesn't mean that I made any progress towards AGI.

You may be right that resistance is futile. But I don't think adaptation is. And there's no reason our adaptation can't be rooted in resistance.

For example, maybe smaller local forums make a comeback and their communities decide to hide all threads behind auth. (I don't necessarily see that happening, just an example.)

And honestly given the stronger feelings people are developing against what I'll just call "creative use of generative AI", I'm starting to think maybe resistance isn't futile... Poisoning original digital art so it's less useful for image generators...social shaming of AI generated music being laundered on platforms...those things do feel like meaningful steps towards resistance.

There are many ways of promoting something, several of which do not require disclosing one's identity. Imagine you were buying a vacuum cleaner -- why would you care who the promoter is?

Credibility comes from the quality of information shared and from the accuracy of one's predictions over time. In fact, the more powerful someone is, the more they have an incentive to lie.

All of the same human dynamics will be present under socialism or communism or whatever you prefer.

Under capitalism, a boss might try to persuade you to work hard harder than you might otherwise for dubious or illusionary future reward.

Under some form of collectivism, there will still be pressure to attend some sort of goal, even if it is non-financial in nature. That pressure will ultimately come in the form of a leader of some form, and one of the tools they will have to achieve that (possibly collective) goal will be to persuade you to work longer and harder than you might otherwise for some dubious or illusionary future reward. Perhaps this future reward won’t be in money, but that won’t change the underlying dynamic.

Do you actually do anything with the data you collect?

As someone who manages commercial building automation system installations, I have never understood the obsession that HN has with residential IAQ sensors. The number will go up if you cook, burn a candle, use a hairdryer, or if there’s wildfire smoke outside and you have a ducted HVAC installation with an outdoor air intake.

In a commercial BAS, IAQ sensors (CO/NO to be more specific) are used to turn on exhaust and make-up air fans to increase the air quality in a space, but in every single thread about IAQ monitoring on HN, nobody ever seems to use the sensor readings to automate their HVAC equipment to do anything. In fact, almost all commercial BAS systems have zero IAQ sensors (especially in offices), the vast majority of them are use for turning on exhaust fans and make-up air units in buildings where cars are driving inside, like a parking ramp or drive-in warehouse.

I guess my question is, why collect this information and do nothing with it? Maybe you actually do something with it, or you monitor local outdoor air quality as a hobby. I’m asking a more general audience than you specifically.

Lastly, ensuring your house is positively pressurized by paying a testing and balancing contractor to come over and adjust your HVAC system will do more to keep out particulate matter than measuring it ever will.

> Discover the PurpleAir PIXEL, one of the first end devices featuring the BMV080 particulate matter sensor for precise local air quality measurement. This user-friendly device provides real-time PM2.5 readings with a quick response time, clearly displayed via LED indicators. The BMV080‘s fanless design ensures completely silent operation, making it both effective and unobtrusive.

https://www2.purpleair.com/products/purpleair-pixel

That's the form factor you'd be looking at when its included with the rest of the supporting circuitry and logic.

So... possibly might be able to get it into a smaller package if the data display is externalized (Purple Air uses LEDs).

My parents are interested in this as one of their use cases is to put it on their e-bike so that they can be made aware of worsening air conditions after they've left the house.

> LLVM just never bothered, despite the early claims that all the intermediate language and "more modern" compiler would enable more optimisation potential.

They did bother but no one seemed to be using it, so a bug snuck in. It took Rust exercising that corner of LLVM to find the bug.

> LLVM is still slower than GCC, even in plain C.

Citation needed. Last time I checked LLVM beat GCC on -O3. Unless you mean compilation performance.

> Where is the problem to quickly null-terminate a pointer+len string and use the quick null-terminated SIMD search?

Why should two nearly idenfical operations have such wildly different performance? And why isn't the safer/saner interface more performant?

My point if compilers and hardware are optimizing for C, it's no surprise no one can approach its speed.

It's like asking why when everyone is optimizing for Chrome no other web browser can approach its speed.

IMVHO it's worthwhile to invest some time playing with the new technologies, as you may appreciate them and found them useful. Give a try to Claude code, Gemini-cli, copilot in vs code with agent mode, or in GitHub.

But I don't think you need to stress, there is a lot of hype and there will be time to learn how to use the winners later.

You could equally argue that there is no point making murder illegal because "all the same dynamics leading to murder" will still happen. They will. Society exists to either curtail or encourage our instincts for a collective purpose.

This is not about that.

This about an institution being rewarded and operating entirely within the law which takes a valuable asset, systematically disenfranchises the people who made it valuable before parasitically sucking it dry for material gain.

That is a pretty unique capitalist dynamic, actually.

Both links are paywalled so I can't comment on what they say (positive or negative). That said, I did attend an interesting lecture about systems that looks a bit at the Yellowstone as a cautionary tale about extrapolating how a system works from observational data. Basically it came down to there are secondary and tertiary effects from systems variables that express visibly differently depending on both the magnitude of the system elements influence and the time where it it changes. Thus making "simple" conclusions like 'wolves did this' often insufficient to explain system behavior and sometimes outright incorrect.

However, the introduction of wolves did, incontrovertibly, add a system element that had not been present before. Exactly what that element was, and how it expressed is up for interpretation :-)

Printed media, radio and television are still very much alive and well, just not as big as they once were. We've past peak Web but it's not going anywhere anytime soon.

We do need new protocols though.

As a social network the web is collapsing but it is entirely possible that a new kind of internet could emerge in its place. After all, routing around damage is part of the essence of the Internet.

Surface Pro X here, the support is meh (see https://github.com/linux-surface/surface-pro-x/issues/7) but good enough to use it casually as a second computer.

In my case the biggest drawback is not being able to use an external screen via HDMI and the sound support (although you can workaround that with BT). Let's not talk about widevine, I managed to eventually get it to work but it was very painful.

If we get full audio support and solve some of the widevine issues, this can easily become a daily driver for when I'm traveling or giving presentations.

I regularly see articles pop in here about OS development happening in China but I find it very hard to find resource in English about what’s actually happening.

Could anyone give an overview of what Huawei and Vivo are doing? I understand it’s mostly RTOS to use on phone. How does it compare to QNX and Linux? Is it as ambitious as Fuchsia?

Apparently they are shipping. It’s weird that we have reached a point where there seem to be two worlds not talking to each other much.

Have you spent much time with the ARC-1 challenge? Their results on that are extremely compelling, showing results close to the initial competition's SOTA (as of closing anyway) with a tiny model and no hacks like data augmentation, pretraining, etc that all of the winning approaches leaned on heavily.

Your criticism makes sense for the maze solving and sudoku sets, of course, but I think it kinda misses the point (there are traditional algos that solve those just fine - it's more about the ability of neural nets to figure them out during training, and known issues with existing recurrent architectures).

Assuming this isn't fake news lol.

The question is how much of that power will we use to do good for the rest of the species on the planet? I’ve just finished reading “Not the end of the world” and found it to be an informative and balanced discussion on the topic that recognizes the vast benefits of human development (to humans), the cost to the rest of the planet and the progress we’ve made in the past 50 years in undoing some of the harm. This is a nuanced topic and deserves that kind of debate.

Eh, the social features of Komoot were never intrusive to me, and among social features of most apps they were some of the most well designed. Local community, very much focused on actually sharing tracks and trying out other people's routes (and maybe commenting with your experience afterwards).

There was a guy in his 60s regularly doing very nice circular hiking routes of 40 to 60 km in our nearby forests, and apart from that just being kind of awesome and impressive to see when you look at local routes, actually walking his routes was often a very nice experience with diverse landscapes often along nice small, less used paths. It was great seeing nice weather in the morning, and then oftentimes without any pre-planning just walk or bike to the forest and just start along one of this guy's routes within a few minutes, all in an incredibly hassle free manner and with a result which pretty much always beat out just following the official hiking trails shown on signs etc. I don't know if there's another app right now where you can so easily profit from the experience and knowledge of your local community.

This is the approach that most workers took in our eastern European countries during socialist era.

It was shitty. Pretty much all services were terrible since people just did the minumum.

I've noticed US going down this path for a few years now and I can't figure out why in the frigging world would you cheer on towards such horrible society.

All the best places I've lived at were great because people cared about the jobs and other work they did.

The problem with capitalism is that something like it (concentrated power begetting additional power at the expense of most of the populace) is nearly guaranteed to crop up in a society which doesn't burn resources actively fighting against it. When fishing for alternatives then, you have to consider:

1. What fraction of our resources do we want to burn while eliminating which of the worst parts of capitalistic tendencies?

2. How do we preserve diffuse power distributions in the face of actors who will actively work against that goal?

Not to trivialize it too much, (1) is just a policy decision. Being completely hands-off is probably sub-optimal. Burning 100% of resources fighting fraud and other abuses isn't ideal either. It's a reasonable framing though for comparing strategies. There's no free lunch, so if somebody sells you a governmental structure which eliminates the worst parts of capitalism without _some_ cost, it's likely snake oil.

Point (2) is the harder one. The majority of people wouldn't mind a little extra power and a few extra resources. If that's possible, it's also (usually) possible to create sub-populations which together have much more power than other groups and thus subvert the goals of your anti-capitalist strategy. How do you create a system that's robust against most individual participants (potentially inadvertently) working against it?

So, sure, let's do away with capitalism. What do you replace it with that's both better and won't revert back?

How else should someone take the statement 'that is the type of search that Google makes no money from' when someone explained what type of searches they do? If Google doesn't make money from it, they don't develop it for search apparently, which is why they haven't progressed in search beyond advertising. You can argue that it needs disrupting, but concluding that 'they make their money from advertising' when that was directly stated by you is not flippant or facile, it is deduction.

You can't eat your cake and still have it. If they refuse to develop an income stream that isn't related to advertising while using practices that use their dominant place in the market to buy other technologies or shut them down, then saying it isn't their fault that the revenue is only advertising is either disingenuous or naive.

driving is partially an activity for fun, yes. my car isn't just a point A to point B tool. when I go A to B, I like to be delighted. And my new car does do that! Zoom zoom :)

This is on top of other reasonable, practical considerations. My choice of car was the best imo in its price range and class overall. Great interior, stylish and sporty, Japanese car. longterm reliability, I can keep my mechanic and do routine stuff myself, I live super near a gas station.

No EV blew me away so why suffer when I can have my car delight me and be a solid price stretched over a bunch of years at 0%? I don't think it's villainous to buy gas in 2025 and it's p out of touch to act like it is (in America)

> All pilots are limited to 200hp or less

One of the more arbitrary and kinda pointless rules. Someone flying a 160 knot 200 hp Piper Arrow with a controllable prop and retractable gear doesn’t need the endorsement. Someone flying a 90 knot fixed gear fixed prop biplane with a 205 hp engine does.

It’s pretty much “use more right rudder”. Although most aircraft with over 200 hp have a constant speed prop so you learn to use manifold pressure and engine speed to set power.

I went from a 145 hp plane to a 235 hp one with about 30 min of instruction during a BFR.

I would say such inventions are as old as 30 years when i first heard of startups / inventors trying to do such stuff. Obviously the tech must be now much more mature. Still, it never got off back then because typing was magnitudes faster than what ever you could do with your hands alone. Learning to do such hand motions had a similiar fate as why alt keyboard layouts always stayed niche - most people have no patience to learn that complicated stuff when they already have learned something early on that works.

Nobody pre-reads documents except in the course of writing the document, so the 20min focus time (I’ve seen this go to 40min sometimes) is really a blessing.

And it’s not just “management wisdom”- it’s “intentional culture”.

I felt that Amazon was a little creepy and maybe even a little cultish when I first started because of the intentionality of culture. They are very intentional about many aspects of corporate culture and the internal jargon continuously reinforces that. For example, you hear references to the leadership principles all the time (every day) and people will regularly use the term “Amazonian” when describing whether actions align with the cultural norms or not. But altogether it works and was a very interesting place to have worked.

They have their own dysfunctions, but I think that the way they manage their corporate culture intentionally is a good thing.

This is like "X guidance" that then becomes mandatory because "To cover ourselves we'll just follow X guidance".

You're describing the same outcome pretending it won't happen.

There's already OpenId. The government can already use it with a YouGov or similar systems which you could integrate with. There's no problem here other than actually trying to force ID for internet access (one of the excuses is the old "who will think of the children", age verification for social media).

Their frustration with plagiarism, inaccuracy, and the "tragedy of the commons" effect on web content is valid, but that is human behavior - they even cite an example.

But "wisdom", if we are going to aspire to that, would look for the ways these tools can be used to better our condition as creators and thinkers, rather than have our opinion be led by a reactive moral narrative not grounded in pragmatism or reality.

To follow up, after experimenting a bit with the source code:

1. Please, for the love of God, and for scientific reproducibility, specify library versions explicitly, and use pyproject.toml instead of an incomplete requirements.txt.

2. The 1,000 Sudoku examples are augmented with hand-coded permutation algorithms, so the actual input data set is more like 1,000,000 examples, not 1,000.
