> 23k seems like a lot,

That is because it's wrong. Sorry, just woke up. I'm in Norway, and it's 23k NOK, or $2300.

The shop said filling my system back up with refrigerant if it was empty would be around $1.3k, and based on what I've heard I don't think that's off by much.

Well first question to my mind is does a CPM actually help? There's a lot of waste in American Healthcare on expensive but fairly useless treatments.

My guess was that a CPM might fall into this category (I did PhD research in bio mechanics in MatSci). So I googled it and it returned a quote:

> Do doctors still use CPM machines? > The machines are no longer widely used because of the multiple studies that found CPM following knee replacement surgery has minimal benefits. However, some surgeons still recommend CPM following knee surgery when the limited pros outweigh the cons in a particular case. (1)

From an insurers perspective it makes sense not to cover a marginally useful piece of equipment. The better use of resources would probably be covering PT where there's movement and weight on the joint.

A quick Google says it takes 4 years to get a license to be an HVAC technician in my state.

I understand large installs at businesses are a different problem, and granted I've only ever installed a mini split, but that was hardly rocket science. And home installs are likely what most people are thinking of here.

In Japan you can get minisplit's installed for $1k a unit, here you regularly find quotes over $10k. Something's gone wrong somewhere.

I don’t think that’s what they were saying, but instead, labor is expensive now because labor is scarce, which is true. And that regulation is expensive, which it is, but also necessary.

Perhaps the question is why wages are not high enough to support these prices (globalization, productivity wage gap over the last fifty years, etc). This will change over time due to structural demographics [1] making labor much more scarce (pushing up wages), we’re still in the early days. Software is not going to eat the trades and HVAC repair.

> Anyway, I don't think that there's anything that it's like to be an LLM. I don't see how anybody who knows how they actually work could think that.

While I have almost zero belief that LLMs are conscious, I just don't think this is so trivially asserted.

The easy half of this is thinking that LLMs aren't conscious given what we know about how they work. The hard part (and very, very famously so) is explaining how _you_ are conscious given what we know about how you work. You can't ignore the second half of this problem when making statements like this... because many of the obvious ways to argue that clearly LLMs aren't conscious would also apply to you.

No face, no case. They have to break it way down, just like at any org. In fact, I would ask for more tests than usual with a test plan/proof they passed. 9k is a little spicy, separate PRs, or an ad hoc huddle with them rubber ducking you through the code. Depends on if you care about this that much or not.

Unless you really trust them, it's up to the contributor to make their reasoning work for the target. Else, they are free to fork it if it's open source :).

I am a believer in using llm codegen as a ride along expert, but it definitely triggers my desire to over test software. I treat most codegen as the most junior coder had written it, and set up guardrails against as many things llm and I can come up with.

Yep, this sums it up perfectly for me. I tend to stay away from the extra stuff since the quality is hit or miss (more often hit than miss to be fair), but really there’s something special about having something like it available. I think as a freely available package Nextcloud is immensely valuable to me. I never say anything bad about it without mentioning that in the same breath nowadays.

I didn't see anything in their comment where they added "and therefore we ought return to rampant extreme poverty", did I miss it? They don't appear to be suggesting anything you say they are, just describing the effects of what exist.

It can be true that consumer protection laws raise the price floor for certain goods and services without "and therefore consumer protection laws are bad".

MathJax lets you select text more often than KaTeX as far as I can tell (some KaTeX formulas act dead unless you start selecting outside them), not that either library give you anything especially useful if you try to copy and paste. MathJax will happily give you useful copy-to-clipboard if you right click.

MathJax has way more accessibility features: https://docs.mathjax.org/en/latest/basic/accessibility.html

A radiologist read my brother-in-law's MRI and contacted him and told him to go directly to the ER and actually wrote up a referral to have him immediately admitted. This happened in the middle of the night since the radiologist was reading them on the night shift. He was admitted and operated on two days later (as he had to be prepared for surgery and have additional pre-op testing done).

No AI replacement is going to be doing that anytime soon.
Maestro — Graph RAG orchestration engine (FastAPI + React + pgvector)
by snowypainter | 2025-11-04 06:26:43+00:00
Hi HN, I’m Minwoo, a solo developer from Seoul. Over the past two months I built Maestro, a deterministic orchestration engine that tries to replicate human judgment — not through LLM reasoning loops, but through a Graph RAG that stores and replays how decisions are made.

What it does

Maestro turns every decision (persona, campaign, trend, draft, publication, comment) into a graph node with embeddings in PostgreSQL pgvector. Each connection (edge) represents a relationship — “produces,” “comment_on,” “related_trend,” etc.

When a user asks,

“Show me drafts related to Trend X,” Maestro: 1. Embeds the query using multilingual-e5-base 2. Retrieves the nearest Trend node via vector similarity 3. Expands along relevant edges (related_trend → draft → publication) 4. Surfaces contextual summaries and KPIs — no extra LLM calls required.

The result is a reasoning-aware search engine that rebuilds why something happened, not just what.

How it works

Backend: FastAPI + Celery + PostgreSQL (pgvector) + Redis + SeaweedFS

Frontend: React 19 + Vite + Zustand + shadcn/ui

AI layer: Hugging Face multilingual-e5-base embeddings

Graph RAG: 9 node types, 7 edge types, deterministic traversal

Architecture: DAG executor (idempotent flows) + self-generative adapters

Every action is an idempotent operator. Flows are chained deterministically through a DSL → DAG pipeline. When two flows’ input/output types match, the system connects them automatically — new features emerge with zero code growth.

Example: comments.search + template.create → "Search comments and create reaction template" No new logic written, just an adapter between existing flows.

It is expensive, but I think you're underestimating the costs.

If the AC catches fire because your electrician skills are bad, what happens? I guess you can rent a ladder if you need one, but they're at least $200 if your split is on the second floor and ladders can be deceptively tricky, and load ratings must be considered. Condensation can kill you and be an extreme cost with mold. Your first mini split is going to take a real long time to install, I promise, assuming you size it right. There is a non trivial risk to life and limb.

This is one of those "Reality has a surprising amount of detail" things.

Spot on article. At this point, I think you should leave the UK if you have a tech business or thinking about raising capital. Either Hong Kong, Singapore, UAE (Dubai) and United States are far better business friendly destinations.

From November onwards, it is going to get alot worse for UK businesses.

For anyone else thinking about building a UK startup today, this is what you will get in return:

> Your friends and family want the best for you. Well, in most cases, as long as you aren’t doing better than them.

This is called "tall poppy syndrome". [0]

> And will steal as much money from your back pocket as they can.

If you are making £125K+ as an employee, you will lose half of it. As a business, that tax rate is only going up and you will lose more money.

Finally, little to no funding or any VCs willing to fund you in the UK.

> 23k seems like a lot, especially so if the leak is somewhere other than a hidden part of the line.

I am inclined to agree. The rear 2½T unit in our rental blew a line last year. Two companies quoted my landlord $10k for a new 2½T condenser and air handler (1 was another renter of his). Even that seemed high to me but I could be out of date

In the end, I had a friend come out and look it over. Leak was near the compressor and he charged well under $1k for the fix, mostly for refrigerant.

I acquired a minisplit for $450 or so (labelled "For export only - not for sale in US or Canada", because it contained R-410 and doesn't meet the current efficiency standards) and installed it myself.

Getting a similar system installed would have been north of $10,000, and before anyone says "well, that would be a licenced HVAC installer", no it wouldn't - it would be a barely-trained person who is simply "supervised" by a licenced HVAC technician.

Thanks for the book rec, seems like it'd be worth reading.

In general it is not worth pursuing changes to an organization, because in some sense the you need the organization more than they need you, and stepping on the toes of too many people with unpopular opinions is just gonna make you look like an idiot, or in the worst case, get you fired. Therefore, people can only rationally ascribe to the the capitalistic view of "vote with your wallet" or "if you don't like your job, just leave."

That's an X11 thing that Wayland had to reimplement because it's so convenient. The problem is when pasting into the terminal something that another program copied into the clipboard. That's ctrl-shift-c.

I thought about remapping copy and paste to their own keys, possibly a single one. Maybe on the number pad, which I never use. Or remapping ctrl-c.

There are lots of AI App builders but not so many new tools for building ai websites (when you dont need auth, db, etc). I built this tool for my own purpose. Not as good as WP or similar but good for a quick 100% custom website. It pushes the code to github automatically for free hosting, free domain, add custom domain free etc.

When you are applying from a job you are more desirable and you aren't desperate so you can take your pick. If your current job is bad then you can't really lose much.

Otherwise you need to be the person at the company who cuts through the bullshit and saves it from when the VibeCodeTechDebt is popping the industry.

You'd need to be negotiating with an actual tradesperson, not someone who is a glorified salesperson / unskilled installer who works for a company that has been acquired in a PE rollup.

The easiest way to find a good tradesman is to ask another tradesman. There is an HVAC person in my local area who will come out and do most jobs (such as, for example, moving an AC) for about $500. A PE rollup firm would quote $10k for such jobs.

The elites are trying to come up with new ways to oppress.

No one voted for this, and the last government was actively voted out for all this sort of bullshit. However, to give a prime example of two faced ideology, we now have a government that had the position that trans-women are women, but as soon as they were elected switched to a trans-phobic position.

Nothing the current government does is based upon their election campaign, nothing we voted for is being pursued, and nothing happening is what we want. Labour are actively corrupt.

The problem isn't tradework costing more, the problem is most people making less money thanks to wage stagnation and can't afford reasonable trade rates. Capital costs for the neccessary tools are also higher than ever.

I can build a house 4x faster today than my father could back in the day, or alternatively with 4x less labor, and yet he could buy a house, 2 cars, and support 3 kids on his single wage. Meanwhile I struggle to do more than just survive in my little shack house built from scrap on an empty plot doing the same thing.

The only jobs that earn me a decent wage is for corporations or for people near or in the top 1% of wage earners.

If the average person made more money I would have more work and more money. But as it is a lot of residential work would be of negative value to me at the prices people can afford, and with less work to do and farther and farther travel distances for it my prices must keep rising to stay solvent.

I think the medium where information transformation happened was for many the only artificial line between what they called processing and what they called thinking. The caveat for others being that thinking is what you do with active awareness, and intuition is what you do otherwise.

That caveat to me is the useful distinction still to ponder.

My point of contention with equivalences to Human thinking still at this point is that AI seems to know more about the world with specificity than any human ever will. Yet it still fails sometimes to be consistent and continuous at thinking from that world where a human wouldn't. Maybe i'm off for this but that feels odd to me if the thinking is truly equivalent.

I have pretty much the same amount of confidence when I receive AI generated or non-AI generated code to review: my confidence is based on the person guiding the LLM, and their ability to that.

Much more so than before, I'll comfortably reject a PR that is hard to follow, for any reason, including size. IMHO, the biggest change that LLMs have brought to the table is that clean code and refactoring are no longer expensive, and should no longer be bargained for, neglected or given the lip service that they have received throughout most of my career. Test suites and documentation, too.

(Given the nature of working with LLMs, I also suspect that clean, idiomatic code is more important than ever, since LLMs have presumably been trained on that, but this is just a personal superstition, that is probably increasingly false, but also feels harmless)

The only time I think it is appropriate to land a large amount of code at once is if it is a single act of entirely brain dead refactoring, doing nothing new, such as renaming a single variable across an entire codebase, or moving/breaking/consolidating a single module or file. And there better be tests. Otherwise, get an LLM to break things up and make things easier for me to understand, for crying out loud: there are precious few reasons left not to make reviewing PRs as easy as possible.

So, I posit that the emotional reaction from certain audiences is still the largest, most exhausting difference.

The author makes an error while explaining Jevons’ Paradox. They say “the cheaper and faster we got at producing coal, the more coal we ended up using”. But that’s not paradoxical at all. That’s basic supply and demand curve from economics 101. It’s exactly what you’d expect.

Whereas if you take the extraordinarily difficult step of opening Wikipedia (https://en.wikipedia.org/wiki/Jevons_paradox), you understand the real paradox. Jevons observed that when steam engines get more efficient and individually use less coal, we end up deploying many more steam engines in many new industries and use cases, increasing coal consumption overall.

This seems like a basic oversight, maybe this guy hasn’t heard of Wikipedia. On the other hand, I think he wants to push the narrative that AI is seeing enormous productivity gains. He does this by using price per token, which has fallen. Very similar to Jevons supposedly observing “coal production”. But the author is struggling to point to new industries and use cases that were opened up by AI, like when we deployed steam engines back in the 1860s. So he misstates Jevons paradox, removes the paradoxical part, and makes it seem like his thesis makes sense.

Jevons’ Paradox could still apply here! I’m not saying it doesn’t. But we just haven’t seen the examples quite yet. A good example would be an observed surge in demand custom built software as software engineers become more efficient. But lower token costs ain’t it.
When you remove money from a marketplace, strange things happen
by vibenex | 2025-11-04 06:32:55+00:00
Has anyone here tried building or studying non-monetary marketplaces?

We’ve been exploring what happens when you strip price out of an exchange system entirely, when value is defined by attention or effort instead of currency. The results have been surprisingly unpredictable.

How do you measure fairness when there’s no price signal? Some people give more than they get, others act more generously because there’s no transaction history to optimize against. It feels like reputation, not ROI, becomes the governing logic.

We started with a simple idea where people could exchange exposure, participation or experiences instead of money. A café might offer free meals in return for content, a gym might trade sessions for Google reviews, all voluntary, no fixed value.

When you remove money, people negotiate differently. They’re less defensive, but also less predictable. Interactions feel more genuine.

Has anyone else noticed similar behavioral shifts when incentives stop being financial?

>easily find evidence that Lenin and others sought to discipline kulaks, but nowhere are the Holodomor's famines mentioned there.

that is what i was talking about - disciplining kulaks, successful peasants, which basically meant destroying significant part of the peasant population there. And if you look at the map i linked - those regions had mostly Ukrainian speaking peasant population.

You probably have different than bolshevik's notion what "disciplining" is. Bolsheviks were outright genociding whole social stratas (and kulaks were one of such a strata) because bolsheviks saw no place for those people in the supposedly beautiful future the bolsheviks were supposedly building. And just for an example - you probably not aware how bolsheviks used chemical weapons against peasant revolt in Tambov region.

This is a tool I need. But I am so tired of stuff like this getting abandoned after 4 months that I am reluctant to even try.

I wonder if the ease of building amazing new projects leads to a sort of cycle of fatigue and end-user resistance that leads to even faster abandonment.

Very cool idea and looks like a neat implementation. I am cheering for your success and cheering even more deeply (in a philosophic sort of way) for this to be still around in few years.

Doolang aims for memory safety with static typing and automatic reference counting, so you won't see classic C/C++ bugs. But it does not claim Rust's level of safety there’s no formal guarantee that safe code can't cause undefined behavior. It's quite safe in practice, just not as strict as Rust.

For complex types (strings, arrays, maps), values are reference-counted and passed by reference. If you pass such a value to a function, you're sharing the same object—mutations affect the original. For primitives (Int, Bool), it's pass-by-value (copy).

I don't really know how this is any different now from the 1990s. I think there is a sense of bottom level on price they'll take for a job due to litigation/insurance concerns. But, handymen are what should be doing a lot of these jobs. I do think there is another concern about quality of workmanship as well. You take on these small jobs, one goes poorly - you take a huge hit on your reputation comparatively and have to fight to get small jobs even more than before. That wasn't as big of a concern before the internet made everyone's reputation so important. Losing one customer wasn't losing the whole market - whereas it is now. A few negative reviews can permanently tank your business.

Since AI is the future, here is what AI says (which is basically sourced from a couple Reddit posts):

"The cost to repair an AC in Hong Kong varies by the problem, but basic repairs can range from approximately HKD $500 to $1,000, while major repairs like a compressor or refrigerant leak can cost HKD $1,500 to $4,000 or more. Inspection fees are often around HKD $500, with the repair costs and any needed parts being quoted separately. "

Basic repair US$64 - $129 Major repair $193 - $515 Inspection $64

Somehow, American HVAC prices are orders of magnitude higher than that.

I'm as skeptical of AI as the next guy, but in this particular case, wouldn't the AI have read your brother-in-law's MRI right after it was taken, and sent him to the ER before he even left the MRI testing room?

I'm not arguing with the GP's point that radiologists don't do many other things that the AI maybe can't do, but it feels like your example is the opposite of that.

And not only that, your example demonstrates a failing of the human's limited amount of time to get all their work done.
