  • I'm right, ain't I?

  • I strongly disagree that memorization is important or foundational to advanced math. It definitely is useful, but you don't need it. And the more advanced your math gets, the less valuable it becomes.

    My experience is that university-level math explicitly tells you to not memorize values and formulas, but to get comfortable finding solutions directly, because then you actually learn what is going on and have methods that are universally useful.

    In the real world memorization is even less useful. You will never be as fast and accurate as a calculator, or remember as many values as a precomputed table has. So why bother?

  • Nice! A big improvement indeed.

    I wished you had showed them with similar sharpness settings though. The FSR 3 image is very oversharpened, while the FSR 4 one has the opposite problem so you can't really compare any details.

  • Yeah I just wanted to illustrate that with some numbers :)

    It's a bit counter-intuitive that frame generation is worse the lower your base frame rate is. And Nvidia in particular has no interest in making it clear that this tool is only really good for making a well-running game run even better, and is not going to give your 5070 "4090 performance" in any meaningful way.

  • I was trying to explain why the game loop would be held back by the rendering speed, even though they run on different hardware.

    If you are bottlenecked by the GPU that means the game loop spends some of its time waiting for the GPU. If you then turn on frame generation, you devote parts of the GPU to doing that, which makes regular rendering slower, making the game loop spend even more time waiting. This will increase input latency.

    Frame generation also needs to delay output of any real frame while it creates and inserts a generated frame. This will add some output latency as well.

    In the opposite scenario, where you are bottlenecked by the CPU, enabling frame generation should in theory not impact the game loop at all. In that case it's the GPU that's waiting for the CPU, and it can use some of those extra resources it has to do frame generation with no impact on input latency.

  • Most games aren't bottlenecked by your CPU at all. It spends a lot of time waiting for the GPU to be done drawing you a picture.

    "Why isn't the game doing other stuff meanwhile?" you might ask, and part of the answer is surely, "Why do stuff faster than the player can see?", while another part is likely a need to syncronize the simulation and the rendering so it doesn't show you some half-finished state, and a third part might be that it would be very confusing for the player to decouple the game state from what they see on screen, like you see yourself aiming at the monster, but actually it moved in between frames so your shot will miss even if the crosshair is dead on.

  • Framegen is worse the lower your base frame rate is.

    The penalty to the speed at which the game runs is much more significant, if you normally run at 40 fps and framegen gives you 60 (30 real) then you have introduced 8 ms of latency just from that. While the same 25% performance cost going from 180 fps to 270 (135 real) adds just 2 ms.

    The lower your real frame rate is the harder it will be to interpolate between frames because the changes between frames are much larger, so it will look worse. Also the lower your frame rate the longer any mishaps will remain on screen, making them more apparent.

  • Yes, darkening your room and then pushing a bright light up against the one-way, taking care to not have it leak into your room, should make the other room brighter so you can see it.

    Not that this is a one-way mirror anyway.

  • I had this happen in a hotel, and being curious I removed the mirror, and yes there was a hole in the wall behind it, no there wasn't a camera there. It was just were they had ran the wiring for the lights on the mirror.

    It would make sense that it serves like an access hatch to a terminal block that feeds the whole room. It's simple, costs nothing, is easy to get to (compared to having it sealed in the wall), protected from splashing and prying guests, and close to where you want most lights and outlets.

  • I doubt these tools would help you. They are primarily for pulling data off devices, spying on them, or controlling them.

    Even if you could buy them as a private individual you wouldn't want to pay that cost. There might be pirated versions, but most who have use of these tools have no interest in pirated software.

    There are extremely skilled people who make a living finding vulnerabilities, so there's not a lot of low-hanging fruit left and those who find serious vulnerabilities have generally worked hard to do so.

    When a single exploit can pay enough that you could pay off all your loans, buy a house, or not have to work again for years, or maybe ever. Why would you go through all the trouble of finding it to release it publicly and get nothing? Especially when it's going to be used by these shady companies either way.

    I'm not saying exploit selling is morally right, it certainly isn't, but if I was offered millions of dollars to do the wrong thing, I'm not sure I would turn that down.

  • My guess: The blocklist is the only way they have of removing it for all those who download it from them when they previously distributed it. And they do that so they can not be held liable for those copies.

    A company like News Corp might go "This was downloaded 50 000 times from you and can be used to bypass access control on 10 000 000 of our articles which would otherwise cost $20 each. So we are suing you for 10 trillion dollars in losses. See you in court."

  • The purpose of this add-on is solely to circumvent access restrictions to copyrighted works. It is clearly a circumvention tool under the DMCA and therefore illegal to distribute in the USA.

    The policy violation is that it breaks US law.

    Guessing here, but Mozilla likely blacklisted it to disable it for all those who had it installed and cover their ass legally. Nobody can accuse them of aiding in the distribution of this illegal tool anymore.

    While uBlock could be used for the same thing, it has a different primary use (blocking ads, which is still legal), so a similar charge against it might be successfully fought.

    The DMCA is a fuck.
