Re:"I'm on a War Footing": Terry Tao and the Crisis in Math on Sunday October 18, 2026 @10:30PM (#50147702)
This tool belongs to somebody (capitalist!) else and in a new world better tools will always win, not individuals anymore. And it feels like to go from being Rembrandt to CVS employee who takes passport pictures - result much better quality and cheaper but no skill and glory.

Interestingly, the dynamics strongly resembles the industrial revolution when from highly skilled manufactures society moved to factories with power machines. And it all came down who owns means of production. Now AI is a new means of production for all white collars jobs and if the industrial revolution taught is the way to go, nothing good will come out of it.

counted six.

not really. it is 300B of market value disappeared. very small sum of cash exchange would be needed.

but it can and will leak into real world as if somebody borrowed cash with saas shares as collateral. now lenders are in deep shit. somebody is missing a lot of money on their balance sheets.

imho, CT is horribly looking car with absolute disregard to any aesthetics. everything else is secondary. it has vibes of Aztec. one of the worst selling car ever.

it will and it does. anybody who owns a smart watch with heart rate monitor can observe it. the proverbial glass is very visible as a spike of resting heart rate and especially horrible on HRV.

besides, there are "glasses" which can take full 750ml bottle. may be most people don't go such extreme but still very good to fool themselves about alcohol volume consumption

I would guess this is the same reason why one can't change git repo history without affecting people working with the repo. Merkle tree all over the store.

It wasn't restricted per se. Just it didn't exist or produced as a civil appliance, so you won't be able to buy it. But civil defense kits usually had the counter, so if you really wanted one you probably could get it. My dad got one right after Chernobyl disaster.
Re:Ask HN: Facing unemployment – what now? on Friday May 16, 2025 @06:19PM (#44010275)
A bit unorthodox advice, start lifting weights. Heavy. Aim to build strength, not muscles or look. 40s is a great age to do this, better than 50s for sure. For men, physical strength gives more confidence, and problems which you perceive hard will look less so when you are able to deadlift 500lb. And yeah, don't quit your current job without getting new one. Bad idea. And don't give away anything for free to your employer.If they want to fire you, make them sweat (in some places it is not easy process).

ps: speaking of taking 3-6-12 months off advises. Irrelevant of your situation, I think we are living through interesting part of the "hockey stick" curve when being out for one year could mean end of the tech career. Things move way too fast, and gaining velocity.

>it's about money, corporate takeover, money, "efficiency," money, green, money, safety third, money, because fuck them that's why, money, $$$, money...

let me rephrase a bit. It is all about shareholders and how to make more money for them. Every single quarter. and if the CEO is not aligned with these values she will be replaced by new one. Not all CEOs are greedy bastards but the whole system is designed to eliminate every single person who cares about something else except short term returns for the shareholders. So good CEOs are out and bad CEOs are in. Survival of the fittest as it is.

nitpick: I wonder how TSP became NP complete. It would require to polynomial time algorithm to validate the solution. I doubt such algorithm does exist.
Re:Far Manager: files and archives in Windows on Saturday August 12, 2023 @07:52PM (#37105258)
As far as I remember Far was always extremely popular. As far as I remember before "free license" there were various cracks readily available. At some point the author gave up and said something along the line, I won't make money from "russians" anyway so please use this "license" and may be you will stop to produce those cracks!

When on Windows, Far becomes tool to go if you are developer. Powerful file browser with shell and quick viewer and editor, also with ability to create shortcuts to dirs and commands. All together it creates this mouse-free flow which many devs like.

Indeed you can extract work from this system. But because of energy conservation it will result to temperature drop. In case if you want to revert the system to its original state you will have to reheat it (return previously extracted work back) AND also spend some work to reorder particles (reduce entropy).
>The video did not explain why the sun is a low entropy source. I found this explaining what I am sharing with you:

to my best understanding, to go from high entropy state to low entropy state you need work to do. The sun is a source of energy to do the work

>If you need to do work in order to revert to the previous state, does it imply you can extract work when going to the first to the second state?

Nope. The work comes from the system coming from ordered state into unordered. Why the problem above is good for intuition because you can work out how to reverse the state. You invent semi-magical barrier which is fully transparent for particles A and reflects particles B, then you start to push such barrier from left to right up to the middle, compressing gas B (and making work!) and leave left part with gas A only, then repeat similar exercise on the right side.

>Given the scenario you just laid out it seems no work can be extracted just by letting mix two substances that are at the same temperature and pressure. But there is something about it that doesn't quite add up to my intuition of symmetry and conservation laws. Could you please elaborate more on that?

As far as I understand this asymmetry was the exact reason why entropy was introduced. Then later explained by Boltzmann via a measure of number of microscopic states.

Naturally second law of thermodynamics forbids perpetual engines.

If somebody needs to build an intuition about entropy he could think about simple problem.

You are given insulated cylinder with a barrier in the middle. Left side of the cylinder filled with ideal gas A, and the right side filled with gas B. If given a particle one can distinguish A from B. The pressure and temperature on both sides are the same. Then you remove the barrier and gases mix. Question: how much work you need to do to revert the system into the original state? Hint: the work is equal to entropy difference between two states.

More generally, if you have proper insulated system and leave it be for a while. All of sudden you will have to do some work to come back to the original state despite energy conservation law holds.

Re:No, You Aren’t Going to Get Rich by Options Trading on Thursday November 10, 2022 @06:51PM (#33555392)
What you describe is directional trade (aims to capture up/down moves in underlying).

Investment banks usually trade in volatility space, also called delta hedged. Main idea they would sell options (calls or puts) by adding extra premium to the fair price. At the same time they make the whole portfolio delta neutral by buying and selling underlying instruments on daily basis. By having significant portfolio one could expect to leak less on the hedging process and may be use some correlation between underlyings and use index futures instead of individual stocks. The whole business is to capture the premium mentioned above without predicting up or down move.

Even if you ignore the whole story about graduation I wonder why this considered ok? According to pov of this guy people should work their normal hours and plus a "little bit" more only because the management decided to save some money not hiring extra personal to provide the coverage.

>What definitely exists in Russia (or at least some big cities) is a system of free after-school classes, where you can go and learn how to solve olympiad-type math problems and become more interested in maths

And for people outside of big cities there were schools-by-correspondence famously running by Moscow State University for math and MIPT for math/physics. The setup was you were mailed a small booklet every month. You had to study the material, solve problems and sent solutions back. The solutions were graded and sent back to you. It was great on so many levels. First and the most important aspect it taught discipline and time management. The material was amazing when you were given gradual increase in complexity instead of sheer volume of simple problems or a few olympiad-level problems which can't be solved if you are not there yet.
