trhway··on Reverse centaurs are the answer to the AI paradox (2025)
The machine may happen to be the Nietzsche's https://en.wikipedia.org/wiki/Übermensch . Nietzsche analytically extrapolated and foreseen the shape of the things to come, while the state of the tech at the time didn't allow to foresee the actual implementation.

>We're Konrad Lorenz's geese, desperate to be led. It's the path of least resistance.

Us being that way may also be considered a result of evolution driven by the natural selection enforced by the society (similar to how we breed cattle for weight and milk production or turkey for wide breast).

trhway··on How to hide from killer drones
how else would you control 2M drones at the same time? Mechanical Turk? Or aerial fight with an enemy AI, thus much quicker reacting, drone.

Like sharpshooters, the drone operators are usually executed instead of being taken POW.
trhway··on How to Hide from Killer Drones
>not least because the drones it's talking about barely have the resolution at altitude to resolve that detail.

the drones are used in groups. That is for example how we have a lot of footage of the drones hitting targets. The drone observers or especially the intelligence drone guiding the group would frequently carry much better camera than the actual kamikaze drones (especially when it comes to high-resolution IR cameras which are expensive). In the fully autonomous AI mode the drone is usually given small target area where to operate (in particular because they aren't yet smart enough to differentiate Ukranians from Russians, so you'd like to confine their operations to a limited area and not letting it into the totally free hunt) and regular 4K camera is sufficient there. Again, there is a lot of footage on YT an TG.

Half the time it is the nighttime and the things are in IR https://news.ycombinator.com/item?id=47000051 . You may still try to camouflage and decrease your IR visibility - stealth planes try to do it, and there are some IR-decreasing covers for tanks and people.

The night time hunt using IR is widely practiced today in Ukraine and even was widely practiced by US and USSR in Afghanistan and Iraq as surroundings gets cooled down and cars, people and say donkeys used to transport weapons in mountains become highly contrast against the surroundings and thus easy to spot visually and to lock IR seeker of a weapon. Saddam used USSR anti-ship missiles, old even then, to attack Iran oil storage tanks at night as the missiles were easily able to lock on that large bright IR emission of the tanks still hot from the day against the cold night desert.

Especially apocalyptic given that they had never knew such things possible.

Later it became routine.

https://youtu.be/YtCTzbh4mNQ?t=62 (narrator saying - "the mushroom cloud reached 65km altitude" ) Our high school military preparedness classes teacher was a retired "Captain of 2nd rank" (subcolonel equivalent in USSR Navy) who had served at that "Novaja Zemlja" islands nuclear testing range. He was describing that regular nukes they would just watch from 20km. While large hydrogen bombs they were watching from like 200km, and it still was awe-fear-inspiring.

trhway··on Lost city discovered beneath Egypt's desert with ancient church
>It's easy to forget how different the Middle East looked before the conquest of Islam starting in 600 AD.

it naturally looked differently due to different climate. For example there was booming agriculture in Carthage back then - modern Tunisia. The climate warming during the first millennia made Mediterranean Basin less grain-production and animal farming suitable while more suitable for the nomadic Arabs riding out of Arabia. That warming also made life more convenient (in particular conditions became much better for agriculture, the backbone of the civilization) in the previously cold and swampy Mid and North Europe where as a result we see the wave of rise of the civilization.

Coincidentally, we have Caliphates decline and Reconquista happening when the climate started to cool down toward the Little Ice Age. The map of Reconquista looks like a geographical climate regions map https://stuffedeyes.com/wp-content/uploads/2017/11/what-was-...

trhway··on What's slowing down the AI buildout
kind of reminded USSR history of 100 years ago - a mostly agrarian country destroyed by war and revolution doing jump into industrialization with electrification being the driving core of it (the other major factor was GULAG - electrification plus unlimited free labor - winning formula :)

https://en.wikipedia.org/wiki/GOELRO

"In 1920, British writer H. G. Wells visited Soviet Russia and met with Vladimir Lenin. Wells believed that it was impossible to realise the Russian revolutionary’s plan, as he wrote in his book Russia in the Shadows:

For Lenin, who like a good orthodox Marxist denounces all "Utopians," has succumbed at last to a Utopia, the Utopia of the electricians. He is throwing all his weight into a scheme for the development of great power stations in Russia to serve whole provinces with light, with transport, and industrial power..."

Our civilization is converging on electricity right now. 200 year ago electricity looked like a set of disparate phenomena. I wonder if in 200 years we'll be basing our society on some new energy form instead of electricity - something like gravitational conductors or some StarTrek singularity generators and plasma coils.

trhway··on GitLost: We Tricked GitHub's AI Agent into Leaking Private Repos
If you expose your private database's raw SQL access to public web, i bet people will find a way.

The same way here, i see the main issue isn't prompt injection, it is publicly accessible agent having access to private repos. What is the important use case for such a config that it warrants such basic security violation?

trhway··on China sentences official to death for taking $325M in bribes
You really don’t know what you’re talking about, don’t you? You’re from a Western country, right?

>White collar criminals often get caught later in their "careers" precisely because they do it for years and years and years without being caught.

You’ve definitely never seen the castles and fleets of exotic cars that government officials in those countries manage to get on their meager government salaries. Yet you post such authoritative comments …

trhway··on China sentences official to death for taking $325M in bribes
>What Cold War propaganda did to Western brains is tragic.

Some weird fantasies you have.

I grew up in USSR. So very well familiar with inner workings of such regimes.

trhway··on China sentences official to death for taking $325M in bribes
>And he did this as a public servant for over 30 years.

and it was discovered just now? May it be that he played exactly by the rules, the real rules, of the regime - corruption being among the foundational rules of it - and thus it was going for 30 years? And right now he just got his turn like it usually happens in totalitarian regimes. The regime will for show find an excuse to execute you if you got your turn, corruption is just the easiest one.

Also note that corruption is for the officials, state treason is for regular citizens. Same as in Russia. The regime wouldn't want to create impression of political disunity among the officials.

>Violating the public trust should be extremely harsh.

definitely. The only question why the comrade Xi is still not executed?

trhway··on China sentences official to death for taking $325M in bribes
As Stalin demonstrated even when you're totally loyal, you're still frequently made victim of the terror.

The point of totalitarian regime is that nobody should feel safe, nobody should have an agency. In particular the people shouldn't be able to obtain safety themselves even by the way of being totally loyal.

I have no doubt that that guy was corrupt like any other official there. Yet, he isn't punished for the corruption. The show needed another star, and he was chosen to be that star.

alternatively, the things can go very opposite to what you're saying as robots/AI will make many jobs more productive requiring less people thus driving the economy even more profitable than the last 20 years. The society wouldn't need those very expensive children for the jobs where robots would do.

If you knew Russian you could enjoy the hysterics their propaganda were stoking in 2022-23 about alleged "combat mosquitos" the Ukrainians had developed. According to the propaganda the mosquitos were specifically able to target Russians based on DNA (interesting that according to the same propaganda Russians and Ukrainians are the same people - how poor mosquitos were supposed to distinguish between Russians and Ukrainians the propaganda didn't specify though)

>going so far as to lecture me about how 20k isn’t enough to raise a kid.

i expressed my opinion. You may have different one. Expressing an opinion different than yours isn't "lecturing".

>I’m also not going to let 1.2mill suddenly equal 20k/yr raising a kid!

using S&P500 as the opportunity cost evaluator the 20k/yr results in even more than $1.2M. I don't see what you're arguing about. Do you have a better opportunity cost evaluator than S&P500?

you've got the wrong peak. 7439m:

https://en.wikipedia.org/wiki/Jengish_Chokusu

3000m is nothing. Mount Shasta is 4200m and we, just regular guys, walked up to its summit without any experience, etc. in 2 days. People easy do it in 1 day.

>I’d check that math - that’s 67k/yr, not 20k/yr. 1.2mill/18 years.

It is meaningless calculating cost by simple division when the endeavor takes 2 decades. Money today are different from money 20 years ago. S&P500 is pretty reasonable and well accepted device to calculate opportunity cost over such long timeframes.

With today tech - cameras, drones - the tragedy would unfold like a reality TV.

Several months ago a woman broke her leg and stuck as a result at 6800m on Pobeda Peak in Russia and died in several days while the whole country was watching https://www.youtube.com/watch?v=hbr02F36YdQ

trhway··on Is the iPhone birth control? Causal evidence from AT&T's 2007-2011 monopoly [pdf]
Actually raising a child costs more than $1.2M - just $20K/year invested in S&P500 over the last 20 years would have grown to more than $1.2M. Or those $20K/year could be spend on the child. And $20K/year is pretty low.

retire? Retiring only on Social Security is pretty tough, and $1.2M would provide like $4K/month income which on top of Social Security may allow for modest lifestyle in some low COL area.

Wrt. the original post i'd agree with GP - better information/education is probably the most powerful birth control.

trhway··on Why jet engines aren't made in China
Russia has just finally declared achieving full "import substitution" for Superjet-100, a regional jet so badly needed in Russia and the first Russian plane to be produced in decades. With domestically sourced parts the plane is now several tons heavier, and with Russian jet engines it has range of only half of the original non-import-substituted plane, and that makes it borderline unusable as a regional jet for Russia.

"Technological sovereignty" sounds like something smart and glorious ... well, in the 6th grade history classes it was called "natural economy" of the feudalism.

China is 10x of Russia, and thus can build higher technological pyramid - the modern technology in my view is like a pyramid where the complexity of achievable technology at the top is defined by how broad is your foundation. The base of China's pyramid is growing by including more and more of its society into modern technological economy, yet it is still smaller than the Western world's pyramid. The original article exactly describes that the China's pyramid is still of not sufficient height/width for such a complex product like modern jet engine.

trhway··on Internal Combustion Engine (2021)
>But they also start and stop way more than a gasoline-only car with stop-start.

they do it very differently. My Prius never does that coughing sound that the start-stop engines frequently do. The powerful electric motor in Prius spins the engine to at least 1000rpm before fuel is injected. That way it is much easy on the engine and much more fuel efficient too.

trhway··on Internal Combustion Engine (2021)
I don’t think Toyota engine does traction from low rpm. Electric motor does it, and moments later already well spinning engine gets the load.

Hearing regular start-stop on intersection gives me sorry feeling for the engine.

trhway··on US Grid Constraints: Towards 40GW+ of Behind-the-Meter Datacenter by 2028?
>I like how balanced their energy mix is. It is very obvious that China is optimizing for capacity and availability. There isn't really a push for clean energy sources for political, or climate, reasons. They are deployed when it makes sense, backed up by robust coal and nuclear sources.

yes, they don't seem to fall for the "solar is unstable" trap and recognize new reality - the solar + wind smoothed by nuclear/gas is the new baseline

To the comment on the coal below : not really. You don't need that much as a smoothing capacity.

trhway··on US Grid Constraints: Towards 40GW+ of Behind-the-Meter Datacenter by 2028?
you can't put an ADU, yet, you can put in 200MW generating capacity.
trhway··on US Grid Constraints: Towards 40GW+ of Behind-the-Meter Datacenter by 2028?
you're just incorrect. You probably missed 2 points :

- battery storage

- and in the article

"However, AI labs and some hyperscalers have relaxed those requirements as there is now a lower uptime tolerance applied to both inference and training, not just training. Many of Meta’s self-built AI datacenters, for example, target just two nines of uptime and forgo backup generators entirely, as detailed in our Industrials Model."

trhway··on US Grid Constraints: Towards 40GW+ of Behind-the-Meter Datacenter by 2028?
Alternatively the crisis can be used to accelerate right development - quickly build up solar farms and transmission lines. Both of these can be done quickly if there were a political will. Yet, that will is missing.

So, we're talking 40GW. Lets see what China does:

https://energyandcleanair.org/china-energy-and-emissions-tre...

"In the first two months of 2026, China added:

32.5 gigawatts (GW) of solar power capacity, down 18% from last year. 11 GW of wind power capacity, up 19% from last year. 20 GW of thermal power capacity, up 414% from last year. 1.2 GW of hydro power capacity, down 36% from last year. 1.2 GW of nuclear power capacity. "

Edit: to the proponents of nuclear - i think nuclear is very damaging to society as it promotes corrupt crony-government capitalism instead of market forces.
