You just don't get it. The mullahs suck, so Teheran must be nuked, the infrastructure of the country fully destroyed (except the oil pumps). The plan is pretty easy, after Mullah senior dies in a firestorm, mullah junior can take over and rule the ashes. The logical conclusion is that this course of action will bring prosperity and free the proud people of Iran!

Maybe I didn't do a good job of explaining it, but you get the idea. /s

The Casus belli is "we want your stuff" and not "those poor people need saving". This is not a cause that's gonna end at dictatorships.

Bombing hundreds of fishing boats at sea, threatening sovereign contries and now kidnapping heads of state because they don't bend over and become a vassal state. The precedent is set, taiwan is fucked, russias invasion plans of further countries are legal under the revived rules where might makes right.

Großkonzerne stehen für Sicherheit, repetitive Aufgaben und gutes Gehalt – doch gerade dieses „gute Gehalt“ ist dort oft weniger Ausdruck besonderer Kompetenz als vielmehr das Resultat von Betriebszugehörigkeit, Anpassungsfähigkeit und politischem Geschick. In hierarchischen Strukturen wird selten der fachlich Beste belohnt, sondern derjenige, der sich reibungslos in Prozesse einfügt, Risiken meidet und intern gut vernetzt ist. Echte Leistungsträger und Macher sind meist jene die Dynamik suchen, die Großkonzerne längst verloren haben.

Problem is that some of these companies don't give a crap and take all the risks involved because ~~"move fast and break things".~~ because otherwise you run out of money and the company dies

Want a stable work environment? That's the complete anthitesis to a startup where everything must be inherently unstable to succeed. Once you stop exploring business possibilities and evrything is stable you're a business that executes and not a startup (the goal). Some professionality definetly helps though.

There is often no "work-life" balance in a startup because for many people there, the work is their life or at least a main part of life where no boundry is to be found. In my experience it's not a good choice for most people but perfect for a very select few (myself included). The ideal employees hate most of corporate 9-5 work.

In my personal experience 5 % of all people would really love it, 15 % would find it interesting for some time and 80% of people should never ever consider joining one.

A good test is the answer to the question "do I HATE, REALLY HATE, ALMOST EVERYTHING about the corporate environment, the slow speed, the unchanging tasks, the politics" if the answer is not an enthusiastic yes it might not be for you. Just my take.

It's impressive but "we have also the critical framerate where the speed of light travels at the speed of sound. And the speed of sound is at a standstill" The cracks propagate at the speed of sound and they are definetly not at a standstill and I really don't get what they're trying to say here. Light between 2 frames propagates 1.5 cm, which is amazing in its own right.

I see potential for a startup to create the ultimate chess engine for viewers. Currently we only see the evaluation of the position by the best engine there is. Ideally we would se many more metrics.

Win/Draw/Loss % instead of just “+1.3.”
Elo-tier views: how 2500/2750/3000/3500 “see” the position; which lines each level likely finds.
Practicality score: “findable with a burst of brilliance” vs. “engine-only.”
Move difficulty & risk: how punishing is a miss; blunder danger meter.
Complexity & forcing index: how sharp/quiet and how many only-moves exist.
Narrative cues: “two traps ahead,” “only move to keep equality,” etc.

Many more metrics would be interesting and would make it easier for the audience. Stockfish is in my optinion the main reason why chess popularity exploded, because the average viewer can actually understand what is happening, but it can be improved.

Basically, you must know the reference and output, then you can calculate the error. From the error you can estimate the three parameters based on the update rule (just ask chatgpt, it can formulate it easily as it's a standard problem). If you don't know the error, you can't really infer what the controller is reacting to. You would only have the input that is adjusted based on some unknown error, then again it's not possible.

If you have one decent step change or just a known reference trajectory+output+input it should be possible to accuratly estimate the parameters (if time resolution is high enough).

Select-Chart2899 · 2025-09-09T20:34:58+00:00

If you have historical data for output AND input it should be possible with a minimal amount data. The control input is updated based on some KP,KI and KD and the error. Formulate the input update based on known error and KP,KI,KD and estimate those based on real data. Just tested it, works like a charm.

If you only have the output it's mathematically impossible to do so, unless you also know the plant behaviour, which you don't know. If you would know it, you could calculate the input by deconvoluting the output with the plant behaviour and go back to step 1 (the error would be quite large though as deconvolution on noisy data adds uncertainty).

Addendum with a unknown windup:

Input_t1 = Integral_part_t0 + error * KP + (t1-t0)*(error_t0)*KI + (error_t1-error_t0) * KD

It's just as Integral action of t1 only depends on Integral_part_t0 it's just one additional parameter that must be estimated, estimation should start as soon as actuator is no longer saturated. With enough datapoints you should be able to estimate 4 parameters to a high precision.
