  • It’s a series where a dragon kidnaps a princess, and a plumber from New York must save her. To do so, he must gather mushrooms by hitting bricks while jumping with his fist, jump on turtles to make them hide in their shell, and dodge fire breathing plants.

    In the most recent 2d incarnation, the fire breathing plants will sing at you.

    The people who made this were on a lot of drugs.



  • I think we can put a specific maximum for a comfortable western lifestyle. You can certainly argue that a comfortable western lifestyle is already far and away better than most of the people on Earth will ever see. This is something of an arbitrary point where past this, most of us are going to agree that it’s excessive.

    It’s USD 10 million.

    Why? Let’s start with the Trinity study:

    https://thepoorswiss.com/updated-trinity-study/

    The original looked at a standard retirement portfolio and asked how much you can withdraw over a thirty year retirement. It took market data from 1925 through 1995 (the updated version linked above goes to 2023) and then checked a thirty year window over that entire period with various withdrawal rates.

    What it found is that if you withdraw 4% of the portfolio the first year, and increasing it by inflation each subsequent year, it’s highly unlikely the portfolio will run out in the 30 year window. The time period covers has market ups and downs, high inflation and low, and this 4% stays.

    The updated study above says a 3.5% withdraw had a high chance of lasting 50 years.

    Lets play it ultra safe and put it at 2.5%. With $10M, we’ll have $250,000/year to play with, and our rules adjust that for inflation.

    (Median household income in Manhattan is $128k)[https://www.point2homes.com/US/Neighborhood/NY/Manhattan-Demographics.html]. We’re pulling almost twice that. I feel comfortable saying a person can live nicely in any city on this income.

    So there you go: $10M. If you want a 100% tax bracket, that’s a good place to put it. Any more money past that is just a game that hurts everyone else.










  • Nope. There is an industry standard way of measuring latency, and it’s measured at the halfway point of drawing the image.

    Edit: you can measure this through Nvidia’s LDAT system, for example, which uses a light sensor placed in the middle of the display combined with detecting the exact moment you create an input. The light sensor picks up a change (such as the muzzle flash in an fps) and measures the difference in time. If you were to make this work on a CRT running at NTSC refresh rates, it would never show less than 8.3ms when in the middle of the screen.

    If you are measuring fairly with techniques we use against LCDs, then yes, CRTs have latency.


  • He mangles some of the pros and cons of CRTs towards the end.

    They aren’t going to be indefinitely reliable. The phosphor goes bad over time and makes for a weaker image. Doubly so for color phosphors. Some of them are aging better than others, but that’s survivorship bias. We might be looking at the last decade where those old CRTs can still be in anything close to widespread use. Will probably be a few working examples here or there in private collections, of course.

    CRTs do have latency, and this is something a lot of people get wrong. A modern flatscreen display can have better latency than CRTs when the hardware takes advantage of it.

    The standard way of measuring latency is at the halfway point of the screen. For NTSC running at 60Hz (which is interlaced down to 30fps (roughly)), that means we have 8.33ms of latency. If you were to hit the button the moment the screen starts the next draw, and the CPU miraculously processes it in time for the draw, then it takes that long for the screen to be drawn to the halfway point and we take our measurement.

    An LCD can have a response time of less than 2ms. That’s on top of the frame draw time, which can easily be 120Hz on modern systems (or more; quite a bit more in some cases). That means you’re looking at (1 / 120) + 2 = 10.3ms of latency, provided your GPU keeps up at 120 fps. Note that this is comparable to a PAL console (which runs at 50Hz) on CRT. A 200Hz LCD with fast pixel response times is superior to NTSC CRTs. >400Hz is running up against the human limit to distinguish frame changes, and we’re getting there with some high end LCDs right now.

    When talking about retro consoles, we’re limited by the hardware feeding the display, and the frame can’t start drawing until the console has transmitted everything. So then you’re looking at the 2ms LCD draw time on top of a full frame time, which for NTSC would be (1 / 60) + 2 = 18.7ms. Which is why lightguns can’t work.
