  • No, that’s not a real problem either. Model search techniques are very mature, the first automated tools for this were released in the 90s, they’ve only gotten better.

    AI can’t ‘train itself’, there is no training required for an optimization problem. A system that queries the value of the objective function - “how good is this solution” - then tweaks parameters according to the optimization algorithm - traffic light timings - and queries the objective function again isn’t training itself, it isn’t learning, it is centuries-old mathematics.

    There’s a lot of intentional and unintentional misinformation around what “AI” is, what it can do, and what it can do that is actually novel. Beyond Generative AI - the new craze - most of what is packaged as AI are mature algorithms applied to an old problem in a stagnant field and then repackaged as a corporate press release.

    Take drug discovery. No “AI” didn’t just make 50 new antibiotics, they just hired a chemist who graduated in the last decade who understands commercial retrosynthetic search tools and who asked the biopharma guy what functional groups they think would work.



  • Victoria 3 was just boring - I say this as a huge fan of Victoria 2.

    I played a few weeks after launch, and - for every one of the 4 countries I tried (Russia, Japan, Denmark, Spain), simply building all the things everywhere and ignoring money made everything trivial.

    The economic simulation was super barebones, the entire thing could be bootstrapped just by building. An entire population of illiterate farmers would become master architects overnight and send GDP to the double digit billions in a few decades.



  • With refresh rates like that, you must be talking about LED billboards.

    These are different from consumer monitors, which mostly use constant LED backlights and a liquid crystal layer to determine color.

    An LED bilboard is going to have a fuckton of singular LEDs - each of which can emit exactly one color - arranged in groups to form full pixels capable of displaying many colors. There is no extra LCD layer between your eyes and the billboard LEDs.

    The reason for the high refresh rates is because each led must be extinguished and and relit to redraw the image, and the eye is very good at picking up this strobe effect.

    The difference vs. a consumer display is that the backlight in a typical monitor is constant. Refreshes the screen involves sending updated instructions to the LCD layer, twisting the crystals and possibly changing the color they allow through.

    To make a crude concrete example:

    Imagine I am shining a white flashlight in your face. In front of the flashlight I put a colored piece of plastic so the light hitting you is colored. Then I change the plastic to one with a (slightly) different color. I do this 120 times per second. That is a typical consumer display.

    Now imagine I am shining a colored flashlight directly in your face. Then I turn it off and grab a flashlight of a different color and shine it in your face. Imagine I do that 120 times per second. That is an LED billboard.

    Which do you think is more likely to give you a headache?

    One final complication - the brightness of the LEDs is variable over time, they received a modulated signal rather than a steady voltage, so at lower refresh rates there will be a noticeable ripple across the image, similar to how early CRT screens could look.

    Increasing the refresh rate hides a lot of these problems.





    1. Hans has admitted to cheating in the past
    2. Hans played a near-perfect game as black against the best player in the world who hadn’t lost as white in years
    3. Hans made some suspiciously good moves quickly, without much time passing
    4. Magnus played a very rare opening that Hans was somehow able to perfectly respond to without skipping a beat

    From these, many people think he cheated. The vibrating butt plug is unlikely, but what is more likely is that Magnus’ prep got leaked and Hans was able to hyper-prepare for a specific line of play.




  • Interesting how you ignore how the US did not recognize the goverment installed by the people of korea (PRK)

    The brief existence of the PRK has essentially no bearing on the civil war. It existed less than a year, and was dismantled in both the South and the North by the actions of the US and Soviet Union.

    Neither power cared to entertain what the people of Korea wanted in the Post-War period.

    I wonder what half-truth or outright lie y’all will respond with next to paint the US and SK as Satan next to the Angelic Soviet Union and DPRK.

    No power were the ‘good guys’. None had the moral high ground. All deserve blame for what happened. The history of the period is one of tragedy and ambition.

    None of that changes the fact that North Korea, backed by the Soviets and later China, started the shooting war by invading the South.
