pmontra··on AI doesn't generate working products, that's still your job
Note that they would also need to keep the economy alive because somebody has to pay them money. They can't let everybody to go unemployed.

Of course (let me go distopic) we could end up with a dozen of one man companies powered by AIs and robots selling or bartering products and services to each other, what's enough to have food, a house with a pool, a doctor and everybody else has died long before.

pmontra··on Physicists Solve a Muon Mystery. Now, Old Results Don't Add Up
I don't understand this argument. Even ancient Greek philosophers could do their time's science because their economy allowed them to have time to think and food to eat and didn't have to go working in the fields. And they passed on their fair share of wrong beliefs that have been debunked only in the last few centuries.

It's in the nature of being humans. Or God created the universe and one is God and knows exactly how everything works. No wrong beliefs but please teach us.

Yeah, Quanta articles are way too long. They could get to the point in one quarter of the length.

Mathematicians proof theorems so they are always correct. Physicists don't have that privilege.
pmontra··on How old is Ann?
It's a kind of cheating because it means not understanding the essence of the problem but with such small numbers enumeration is a viable strategy.

> Mary is 24 years old. She is twice as old as Ann was

So Ann was 12

> when Mary was as old as Ann is now

So Mary is older than Ann.

The age of Ann is somewhere between 12 and 24. Without much thinking I'd say that probably 12 and 24 are not included and probably it is an even number.

We can test each of them.

If Ann is 14 now, when Mary was 14 (10 years ago) Ann was 4 year old and Mary would be 8 now, this is not the solution.

If Ann is 16 now, when Mary was 16 (8 years ago) Ann was 8, Mary would be 16 now, nope.

If Ann is 18 now, when Mary was 18 (6 years ago) Ann was 12, Mary would be 24 now and she is. This is the solution.

Ann is 18.

pmontra··on EYG: A Programming Language for Humans
Exactly: even with such small programs I had to note down values and I made mistakes at tracking them.

pmontra··on Ars Astronomica – English translations of rare Hebrew and Latin astronomy texts
I don't belong to any of those categories of people but I'm glad that you took the effort to build this site. I didn't know about those texts and I will at least skim through a few of them now. Thanks.
pmontra··on Our position on open-weights models
You would have to eradicate the desire to command other people. The wish for power which is different from the wish to be praised, as forcing somebody to do something is different from convincing somebody to do something.

About your question

> how many variables can you really remember at once?

and our brain being a bad runtime for programming:

I started programming on a Sinclair ZX81 with 1 kB of RAM. I wrote my program on paper, reasoned about it by tracing variables on paper and eventually I typed in the program on the keyboard and run it. That was much better than typing line numbers and BASIC commands directly into the REPL.

Of course I had bugs and the actual values of those variables surprised me. They still do but I have a much wider view on the software now, usually a couple of 100x50 columns of code side by side. The ability to follow the values is not much better, but values are seldom the important matter, at least in web development, backend and frontend. It's more about the control flow and the data structure. That's more similar to the organizational issues of many other human activities. This goes there, that goes into that other place. My old 1 kB computer programs had little space for organization.

pmontra··on Git rebase -I is not that scary
The HN title is "Git rebase -I etc" but the post title is "Git rebase -i"

I guess a keyboard auto corrected i into I.

pmontra··on Fields Medals 2026
Fields medals are for humans. We can create an award for AIs for the same reason for humans and machines don't compete against each other in sports. Machines are usually faster and stronger.
pmontra··on ScreenWall – Turn old phones into synced widgets for your space
I never sell anything, everything finds a new life.

I got a Sony Xperia Compact from maybe 2016. I use it as a bicycle navigator / recorder. Recently it stopped reading SIMs, probably rusty contacts, but all I need is wifi to update OSMAnd and send me the tracks I recorded.

I also have a very old tablet, maybe 2014. My SO uses it to view movies with VLC and TV via TVHeadend.

pmontra··on Map of the world's great castles and fortresses
Interesting but very difficult to perform in the right way. Example: Italy has maybe 45k buildings that could show on that map https://it.wikipedia.org/wiki/Categoria:Castelli_d%27Italia but they can't be collected by looking at the English Wikipedia so it's almost empty compared to what could be. Other countries, same problem.

Somebody suggested in other comments that the data could be from OpenStreetMap. Or let people add their own castles, but then you have all the sort of problems of content moderation.

pmontra··on You only need the frontier model for one single edit
I've been doing more or less this (from the post) for months:

> plan deeply, then capture the plan as a todo list, then start.

I do the plan deeply phase by writing a 50 line specification myself and then asking Claude to evaluate it, find what I missed, ask questions. I answer the question and we iterate until I know that we have what I had in mind to do.

Then I ask it to write the implementation plan, that I might end up reviewing because it always asks some more question. Finally it implements the steps.

If the planning was good the implementation is fast.

pmontra··on China's open-weights AI strategy is winning
Using the cheaper model is also a business decision. We don't know why they are using the Chinese models: openness or money or both or a third one?
pmontra··on China’s open-weights AI strategy is winning
Frankly I don't see much difference between Claude and DeepSeek except in the price. I use the Pro plan to work for a customer of mine and I topped up $2 on DeepSeek in late May for personal use. I worked on 3 projects and I still have $0.72 left. The Chinese companies will win on price, not openness.
pmontra··on The Kimi K3 Moment
Possibly, but they already had bullet trains in 2015. I've been on a few of them.
pmontra··on The Kimi K3 Moment
Paris has a metro station everywhere at least in what a tourist can assume to be an enlarged city center. Tokyo is another city with a lot of metro stations. Manhattan too, at least up to Central Park (but 20+ since my last visit.) I don't remember Shanghai to stand out positively or negatively, but 11 years can be a long time.
pmontra··on The Kimi K3 Moment
I've been in China in 2015 and like anywhere else in the world it was very mixed: some urban areas like central NY or central Madrid and Milan (or much shinier) and some rural areas like 200 year ago, but inevitably with electronics.

Basically in every country of the world you can travel one hour from big cities and get in a place deep in the fields or the woods with very different needs and dynamics from the city. They could be different countries and maybe both cities and countryside will be better off if we could have fractally composed states with different laws and regulations.

pmontra··on So you want to learn physics (second edition, 2021)
I break it down in reverse order to let you understand how I get a gist of that definition

wavefunction, for example light or any particle, this can't be argued.

the complex plane, because? But a complex number is only a pair of numbers and I know that in polar notation it's handy for:

rotation! And I remember that the electric and magnetic components are on orthogonal planes so we are back to complex numbers and maybe the components rotate, but how about neutral particles? But they are not neutral inside. I think that I'm already off track, very lost.

Energy = frequency, because I know that higher frequency photons are more energetic.

Finally, usually we learn about kinetic energy, then E = mc^2 and maybe about the relativistic effects, without the formula. Those things can be understood easily and are taught at school. The jump to angular rotation and the complex plane is something that few people are exposed to and, as I hope to have demonstrated, it's not easy to map to common experiences, which could be inevitable.

pmontra··on House passes bill to enact year-round Daylight Saving Time across the country
Northern countries have a lot of light in summer and a lot of darkness in winter anyway. I saw the Sun setting at 23:00 in Iceland at the end of June and rising at 02:00 and pitch black in Denmark at 15:30 in December. What can DST change there?

On the other side, equatorial countries have about the same sunset and dawn all year long. Again, DST is useless.

Where DST is useful is in a place like the one I'm living at, at 45 degrees North. I'd go with permanent DST plus an extra DST in summer. Basically it's what Spain have been doing for almost a century.

It's cloudy and still reasonably bright outside here. It will be dark past 22:00. I'd take an extra hour of light in the evening and darkness until 6:00 in the morning. It matches the time people goes to sleep and wake up here.

pmontra··on My midlife crisis Corolla is fast, furious, and modded
Do you mean a real Land Cruiser, like the ones that can cross deserts? I'm with you.
pmontra··on My midlife crisis Corolla is fast, furious, and modded
Every car can brake, turn and accelerate much harder than any of us will even think to do especially turning and braking. But you pinpointed why we must not attempt to reach for the limit, not for us but for the others. And anyway a normal car won't lay long if driven like a racing car. Every single component is not designed for that.

pmontra··on The zero-cost fallacy: open-source software in the agentic era
All of those companies have very compelling reasons to provide those tools for free, as in (most importantly dor adoption) no money asked and (less importantly) open source. They make money because of the number of people using those tools. They are a bridge head into controlling their own share of the market.

So: investment, not good will.

pmontra··on The zero-cost fallacy: open-source software in the agentic era
I'm not sure what level of detail those prompts you write about have so I might misunderstand you.

Before AI we had prompts called "requirements" and of course they were the starting point for reviewing code: the customer needs X, the code doing that is Y.

With agents that prompt became much longer, with the original requirement a short note at the beginning of the conversation with the AI, but the resulting code is about the same size. Maybe in YOLO development the original requirement is all the AI needs but I'll be surprised because requirements from customers are too fuzzy and can be turned into very different features, often too different from what the customers had in mind.

Actually I never looked at the detailed prompts of coworkers, only at the original requirements from customers. How they instructed their agents is not particularly interesting except maybe to get a gist of the different approaches.

pmontra··on How to stop Claude from saying load-bearing
Why when I read an how to stop Claude from saying X, I grep my saved conversations and I find no occurrences of X? I wonder if I'm using it differently from anybody else. It happens with coworkers too.
pmontra··on Building and shipping Mac and iOS apps without opening Xcode
RYO is the best way to learn, if you have the time to learn. After building one own solution one is able to assess the strengths and weaknesses of what other more experienced people built. Without the learning phase those other solutions are incomprehensible black boxes. The trick is not to skip the phase in which one researches available solutions.

I started preparing for the worst.
