  • Common misuse of words. Decimate means reduce by 1/10 not almost completely destroy. Exponential growth. The variable has to be in the exponent if it’s a constant exponent that is polynomial growth. Gaslighting isn’t just lying. It’s making someone belive that they can’t trust their own memories or experiences so they believe you despite evidence to the contrary.








  • For ntsc vhs players it wasnt a component in the vcr that was made for copy protection. They would add garbled color burst signals. This would desync the automatic color burst sync system on the vcr.

    CRT TVs didn’t need this component but some fancy tvs would also have the same problem with macrovission.

    The color burst system was actually a pretty cool invention from the time broadcast started to add color. They needed to be able stay compatible with existing black and white tv.

    The solution was to not change the black and white image being sent but add the color offset information on a higher frequency and color TVs would combine the signals.

    This was easy for CRT as the electron beam would sweep across the screen changing intensity as it hit each black and white pixel.

    To display color each black and white pixel was a RGB triangle of pixels. So you would add small offset to the beam up or down to make it more or less green and left or right to adjust the red and blue.

    Those adjustment knobs on old tvs were in part you manually targeting the beam adjustment to hit the pixels just right.

    VCRs didn’t usually have these adjustments so they needed a auto system to keep the color synced in the recording.


  • I grew up near an area where a large number high net worth people. For example as a kid I thought Lamborghini was a common car because I saw them all the time.

    In my experience lots of money brings out your true self and let’s you act the way you want. So if you are inclined to be self centered and an asshole you can be a massive asshole. You can also be generous and kind.

    Most rich people are pretty normal. However the normal ones do try to not make it known that they are rich. So you often don’t notice the normal rich people.

    It’s also hard to tell the difference between a person who lives on a 200k a year income and a person with a double digit millions net worth.

    I had a friend as a teen. I invited him to go diving with me as he had never been. He showed up with a 20k wetsuite.




  • The solution for this is usually counter training. Granted my experience is on the opposite end training ai vision systems to id real objects.

    So you train up your detector ai on hand tagged images. When it gets good you use it to train a generator ai until the generator is good at fooling the detector.

    Then you train the detector on new tagged real data and the new ai generated data. Once it’s good at detection again you train the generator ai on the new detector.

    Repeate several times and you usually get a solid detector and a good generator as a side effect.

    The thing is you need new real human tagged data for each new generation. None of the companies want to generate new human tagged data sets as it’s expensive.
