Thanks for the breakdown — this is exactly the kind of feedback I needed.

You’re right about my query flow: I’m still doing separate LLM calls for the router, analyzer, and rewriter. Merging that into one should cut latency a lot, especially since Qwen2.5-7B-AWQ on an RTX 4000 Ada only gives me ~15–25 tok/s.

The BM25 point is spot-on too. I’ve been running pure vector search (BGE-base-en-v1.5 + FAISS, reranked with bge-reranker-v2-m3). Adding BM25 with dynamic weighting — especially for exact-match queries like titles/authors — is something I really shouldn’t keep putting off.

Using the cross-encoder as the evaluator is probably the easiest fix. My current GOOD/UNSURE/BAD scoring uses the same Qwen model, which is the circular issue I mentioned. Since I’m already running the cross-encoder, letting it handle the thresholding would let me drop the LLM evaluator entirely.

No caching yet, but I’ll start with exact-match hashing and layer semantic caching later.

Model-wise: Qwen2.5-7B-AWQ on GPU, with Qwen2.5-14B on CPU as a slow fallback. AWQ is what makes the 8GB VRAM setup workable.

Really appreciate you taking the time — I’ll open issues for hybrid search + caching this week.

I like the general idea, but try playing devil's advocate with it! I went with the topic of trump and transgender rights and tried to formulate a pro-trump comment that would pass. It was not easy! I was downright civil by the end of it, describing a somewhat credible viewpoint that might lead someone to argue the "wrong" side. It seemed to find the opinion itself offensive, and how can you have a discussion if only one opinion is allowed?

Meanwhile my first, low effort comment arguing the "correct" opinion got published directly.

Conservatives are gonna scream that their views are being censored by this tool, and as it currently stands, I'd have to agree with them!

Edit to add: it did a lot better with non-political topics, and if I'm being honest, I've never ever seen a productive discussion online on a political topic. I'm not sure they can exist! So I would honestly want this tool for any forum I'm interested in viewing. I think. Pending further testing.

Maybe not 25,but IBM Watson beat humans at Jeopardy over 10 years ago. The technology has been there, the difference is the willingness to burn money on it in hopes of capturing exponential revenue from disrupting industries.

Obviously the costs have come down but if IBM felt like burning 100 Billion in 2012 I'm pretty sure they could have a similarly impressive chat bot. Just not sure how they would have ever recouped the revenue.

And the reason 'cool picture' is way more important than 'cool technique' is because the technique is essentially no longer part of the art / picture at completion.

You've just got the sausage, and there's (not necessarily) any indication of how it was made inherent to the sausage - even if the way the sausage is made is cooler than the sausage itself.

(that analogy got tiresome quickly)

OpenAI is already building complex user models. And I mean, super detailed user models - where you are from, what you do, what are your most vulnerable weaknesses, what you care about the most and everything else. This is information even the world's largest advertising company would struggle to put together across their fragmented eco-system (Gmail, Search, etc), but OpenAI has all this on a silver platter. And that scares me, because, a lot of people use ChatGPT as a therapist. We know this because of their advertising intent which they've explicitly expressed. Advertising requires good user models to work (so advertisers can efficiently target their audience) and it is the only way to prove ROI to the advertisers. "But, OpenAI said they won't do targeted ads..". Remember, Google said "Don't be evil" once upon a time too..

That's ok, we use ChatGPT only for coding. We should be good, right? Umm, no. They already explicitly expressed the intention to take a percentage of your revenue if you shipped something with ChatGPT, so even the tech guys aren't safe.

"As intelligence moves into scientific research, drug discovery, energy systems, and financial modeling, new economic models will emerge. Licensing, IP-based agreements, and outcome-based pricing will share in the value created. That is how the internet evolved. Intelligence will follow the same path."

"Intelligence will follow the same path."

So yes, OpenAI has the best chance to win on the consumer side than anyone else. But, that's not necessarily a good thing (and the OpenAI fanboys will hate me for pointing this out).

The article skips that i think most realistic and plausible option - fuel cell using hydrogen extracted from the standard hydrocarbon fuel right on the truck. Thus hydrogen would be present only in the short path - from fuel splitter to the fuel call. The fuel cell has higher efficiency than ICE and having electrical engine works better for trucks than ICE too. Such setup is overkill, at least for near future, for regular cars, while for trucks it seems worth the investment.

Read their comment and yours? What great advice. I would suggest you do the same, but I think you'll continue to misread it.

> No one is going to pay you to take your waste away and dispose of it. You would have to pay them.

> lol, paying someone to "take your waste away and dispose of it" has been a stable of the "recycle" industry in western countries for 3 decades now.

They are saying that paying to dispose of the clothes/waste is how it's done. And then... you said the same thing. Perhaps you're assuming they're just taking a guess, rather than coming at it with understanding that this is how it has been done for a while.

Outside of work I don't know anyone who pays for AI.

But I have noticed that everyone seems to be using ChatGPT as the generic term for AI. They will google something and then refer to the Gemini summary as "ChatGPT says...". I tried to find out what model/version one of my friends was using when he was talking about ChatGPT and it was "the free one that comes with Android"... So Gemini.

Anecdata point: I canceled my ChatGPT pro subscription last year over some shitty thing Altman did at OpenAI and easily moved over to Claude. The only thing I took with me was the system prompt or whatever it's called, I couldn't care less about my conversation history. I'm planning to do the same thing with my Claude subscription if Anthropic kowtows to the Pentagon. These services are not sticky at all IMO.

You’ve gotta read the code. It doesn’t matter how it got there but if you don’t fully understand it (which implies reading it) don’t get mad when you try to push slop on people. It’s the equivalent of asking an LLM to write an email for somebody else to read that you didn’t read yourself. It’s basic human trust - of course people get annoyed with you. You’re untrustworthy.

AI coding tools are everywhere now, but there's a difference between letting the and actually using it .

I wrote about my experience with both approaches:
1. " " a VSCode extension (spoiler: ended up with code I couldn't debug)
2. Using AI as a while building my game (much better results)

The takeaway? AI amplifies skill, it doesn't replace it. The people getting the most out of these tools already know what good code looks like.

I think we’re at the peak, or close to it for these memory shenanigans. OpenAI who is largely responsible for the shortage, just doesn’t have the capital to pay for it. It’s only a matter of time before chickens come home to roost and the bill is due. OpenAI is promising hundreds of billions in capex but has no where near that cash on hand, and its cash flow is abysmal considering the spend.

Unless there is a true breakthrough, beyond AGI into super intelligence on existing, or near term, hardware— I just don’t see how “trust me bro,” can keep its spending party going. Competition is incredibly stiff, and it’s pretty likely we’re at the point of diminishing returns without an absolute breakthrough.

The end result is going to be RAM prices tanking in 18-24 months. The only upside will be for consumers who will likely gain the ability to run much larger open source models locally.

I don’t really understand the advantage of doing it this way vs having them pay directly.

Re debt loads - does the debt load actually materially affect default risk in this case? It’s not like US bonds are officially rated as high risk, at least. Debt to GDP is one thing but without a comparison to other bonds and their associated debt to GDP and a relationship inferred from that data it doesn’t really say anything in a vacuum. Why would it be done this way instead of just paying directly? As opposed to the more straightforward explanation of US bonds just having a favorable payout to risk ratio vs other options. It just smells like some kind of conspiratorial thinking and I’m not sure if it actually adds up.

Honestly asking by the way, I haven’t seen anyone spell out the theory and it just seems quite hand wavey to me.

If you listen to the Woodstock soundtrack it is clear that Hendrix was on a completely different musical level than anyone else in that scene. Ravi Shankar was probably the only person there above him from a chops perspective and possibly in the expressivity department as well. But when it came to sheer inventiveness no one was close to Hendrix. I cannot imagine what it must have been like to see and hear him. It must have felt like an alien was performing.

According to polling, yes: https://www.cnn.com/2015/07/02/politics/confederate-flag-pol.... For people who grew up in the 1980s and 1990s in the south, it was a generic symbol of rebellion or regional rivalry. Remember, Dukes of Hazzard, which aired in the 1980s, was a liberal show about southern boys fighting corrupt politicians and greedy businessmen.

Now you can say “hey, maybe you shouldn’t have picked that particular flag as a symbol to mean ‘fuck the Patriots.’” And you’d be right! But that doesn’t change the fact that it did happen over a long time period.

I like the idea of swappable batteries in theory, but in reality... well... that's a lot of logistics and a lot of potential for things to go wrong. Consider the swappable propane tank market, for instance; it's clear that returning cans need refurbishment and testing before you can give them back out to people. This implies it probably can't be just done on-site at a gas station.

They also weigh an absolute ton, so specialized lift equipment is needed; they take up space and will be very difficult to move around. So, are we expecting to stock a huge pile of batteries somewhere with an automatic loader/unloader that can handle multiple people at once with a quick turnover rate that can put away a 2000 pound battery? It's just too much infra, compared to a charging station...

And then there's the matter of the vehicle design; chassis rigidity is important and batteries, being a huge weight, need to be positioned properly with enough load bearing structure around them to support this. I'm imagining a hydraulic lift raising a 2000 pound battery up into my car; some massive brace needs to be attached below it to hold it up. Talk about difficult to get right; we've got harsh conditions like road salt and rust to deal with, and we have to make a fully automatable fastening device that can work at a random gas station with any brand of car... yikes.

You're actually much closer to the idea with the reduce-capacity idea. I had a Ford Focus Electric a while ago that had about 80km of range on a good day. This was more than enough for 90% of my driving; my old SUV handled the rest. Net carbon savings were huge; pity it was totaled in an accident or I'd have kept it going. Even at almost 10 years old it still kept a charge no problem and was a delight to drive compared to a normal Focus. My current EV has far more range but feels heavy and ponderous despite nearly 500 HP.

Yup this is just another case of the HN bubble. I polled a bunch of non technical friends recently who I know use AI on a daily basis. Out of 10+ maybe 2 had ever heard of Claude, and no one had any interest in trying it.

ChapGPT has become the AI verb, and in the consumer space it is not getting dethroned.

It looks like you want to improve your personal communication skills. You might find most of what you need in the "self help" category.

In fact, there are still bookstores where you can skim books. I find the smaller selection there easier to deal with than the infinity of choices at online stores.

Explaining concepts and ideas, in my opinion, is a bit different, so look at this article to get some ideas.[0]

The other side of this coin is the idea of "presentation", on which many books have been written. While they won't help you with personal communication specifically, they should cover getting your point across effectively, hopefully simply.

There's a well-known 10/20/30 rule of presentations by Guy Kawasaki, an early Apple employee [1], and of course, complex books, and entire courses. Skim.

Hopefully, others here can recommend what helped them.

All the more reason to start now I guess. Putting it off isn't going to get them that knowledge and experience any sooner. If something happens over the next 10 years that eliminates our need for memory chips things will probably be either too messed up or too wonderful for anyone to cry over the years they needlessly spent trying to secure a domestic source of RAM.

> See the word "effective". Think about the road space that a bus requires but doesn't use if it is just once per 10 minutes.

Excepting the case of a dedicated bus lane, the amount of road space a bus is preventing other cars from taking up at a given time is equal to the size of the bus. Technically, it's less than that in the case of bus stops littered amongst parking. In the case of a dedicated lane, it reduces the maximum throughput of the thoroughfare, but it's not a simple thing to model as there are other effects that the bus can have to reduce the number of cars when the rate limit of thoroughfare would be pertinent (i.e. usually rush hour). Just saying "think about it" when saying a bus takes up the space of 100+ cars doesn't really substantiate such a bold claim.

> Yes, I'm talking about the drivers that are needed for a reasonable 16-hour bus service. And the typical ratio is actually a bit more than 3 drivers per 1 bus.

> No. I'm saying that on _average_ there are 15 people in a bus. More during the rush hour, fewer during the off-hours.

If there is an average of 15 passengers on the bus during the operations of the bus and there is an average of 1 driver on the bus during the operations of the bus, then it is 1/16th occupied by driver(s). For it to be taken 20% by driver occupancy, then it would require there to be an average of 4 passengers on the bus during operations.

I’ve read the GDPR has zero impacts on national security/law enforcement. It applies weakly to other state functions.

I’ve also seen cases where GDPR is used against religious groups that have a strong religious justification for keeping lists of believers. Think Orthodox Jews and the Catholic Church, which regard family trees and baptismal certificates as semi-sacred. And kept on paper or scrolls.

Not sure what to think about that. Regulating a sacred scroll like a database table seems wrong.

Google is doing a much better job integrating AI into existing products. Gemini CLI and such seem just like a way to keep the leading competitors humble (a la iOS vs android). They're also building AI tooling tailored to specific companies (like the Goldman thing just announced) and have the cloud infra to back it up. I really only see Anthropic and Google surviving in 10 years.

I don't disagree with your numbers, but "and then burned in a furnace because no one else wants it" is doing a lot of work.

Why does nobody want it? If it is being burned off because nobody wants it, then it effectively has less value after compressing and delivering it than the natural gas itself (or as you say, they'd be selling it and burning the natural gas instead).

The truth is, you can burn it off and save the cost and trouble of purifying and storing it (which also uses energy and produces carbon), especially when using it in fuel cells requires 99.99% purity. You couldn't just pipe it over to a data center or power plant.

It's worth considering also that not only is the hydrogen that would come out dirtier (because it's being replaced by natural gas), it's also making the natural gas dirtier, because you're burning methane instead of hydrogen to refine it.

I'm not sure how we got on to games as resource hogs when Teams uses 2GiB of RAM and Windows itself uses 4GiB of RAM.

I work in gamedev, so perhaps I'm a bit sensitive, and I understand that general purpose engines aren't as light on resources as the handcrafted ones that nobody can afford to make anymore... but we're not anywhere close to the layers of waste and abstraction that presents itself when using webtech for desktop apps by default.

OpenAI lost the race to nerds' hearts. In the latest benchmarks, OpenAI is simultaneously cheaper (like 50% less?) and scores hire in coding and tool use benchmarks (GPT-5.3-Codex trounces Opus 4.6), yet all the coders want to marry Anthropic. I don't think OpenAI understands how to sell, if they even had a product to sell.

I mean, how is it any worse than 'google'?

chatgpt is generic (as in, no prior meaning attached, except for the few people in the world who understand what GPT stands for). It's simple - even a non-english speaker can say it easily, and doesn't require one to be native to know how to pronounce it (this is a difficult concept for a native english speaker to grok).

These features makes for a good name.

It's a joint ignorance of how these frontier models get baked and what consumers want.

Many pundits think it's just a matter of scraping the internet and having a few ML scientists run ablation experiments to tune hyperparameters. That hasn't been true for over a year. The current requirements are more org-scale, more payoff from scale, more moat. The main legitimate competitive threat is adversarial distillation.

Many pundits also think that consumers don't want to pay a premium for small differences on the margin. That is very wrong-headed. I pay $200/month to a frontier lab because, even though it's only a few % higher in benchmark scores, it is 5x more useful on the margin.

You've actually hit on the most important point: Although Oslo was sold as a two-state solution, the Israelis never agreed in writing to a Palestinian state.

The Israelis showed an incredible amount of bad faith. Rabin said in one of his last speeches that there would never be a Palestinian state - only a semi-autonomous entity under Israeli control. The Israelis never halted settlement construction. After Rabin was assassinated by the Israeli Right, Netanyahu deliberately sabotaged Oslo for years (which he brags about today), refusing to withdraw from the occupied territories as agreed.

After 7 years of this, with a Palestinian state no closer at all, a top Israeli politician (soon to become PM) staged a deliberate provocation, and Israeli forces began massacring Palestinian civilians.

Of course there were thoughts in the PLO about the possibility of future armed resistance. They would have been crazy not to think about that possibility. But they preferred a negotiated two-state solution, and they tried to get it for 7 years. After the Israelis started massacring Palestinian civilians, it would have been impossible for the PLO to keep a lid on the violence.

Re: "Europe is not doing fine: Europe is definitely a declining, unstable (lots of far-right vs far-left parties opposing themselves in elections in many EU countries now) empire."

If this is reality in Europe, which is perhaps likely, then by comparison, the US has devolved into failed-state status. Better a slow decline than a catastrophic fall into the constitutional/regulatory/legal/technological/scientific abyss.

Even if Europe has insurmountable problems, its best move forward is to decouple strategically from the US, and these days, all things strategic are underpinned by information technology. The fact that Europe (soon to be followed by Canada, Australia and New Zealand) is heading down this path is why the US has hit the panic button[0].

Re: "The US is the US and in three years there's going to be another president. But the EU's problems are much deeper."

The US may have another president or even another style of president, but that wont stop this migration away from American technological/strategic hegemony; because at this level and at this scale, complete trust by former allies, once lost, will never be regained. The US century is now over.

Thankfully open source software is there as an alternative to that US software. I guess it's no co-incidence that LibreOffice and Linux both have their roots in Europe.

For this, I screenshotted the demo panel and asked chatgpt to generate relevant prompt. Here it is: https://sharetext.io/zy6ccjrm

Then, tested with demo question and a sample comment of mine as answer to it:

Input text: `Die Hard: Is It a Christmas Movie?`

Comment: `nop, its not actually`
