It's not a question of where the car is from! It's a simple question of weight ratios! A one gram strand of noodle could not carry a 1 tonne car.

PVS-based culling is very different from the kind of fog of war system in discussion here. The cases that these FoW systems purports to deal with would all be "pass" cases for PVS culling.

PVS culling solves the informational/strategic advantage aspect provided by wallhacks, but not the pre-aiming reaction-time advantage in a peeker vs holder scenario.

The many tradeoffs involved are not trivial, this can only feasibly work well on LAN.

This is the reason why Valorant is the least playable among all competitive shooters if your internet is anything lesser than Google campus fiber, ironically in spite of having even-slower-than-CS movement physics on its side to mask the problem.

Riot conveniently cherry picks the best case scenario and handwaves the actual technical tradeoffs in their smug "we solved peeker's advantage!" engineering blog posts that are really just barely-disguised monorail Gish gallop.

It's more that momentum-based defogging means that the peeker has control over how to manipulate the server's prediction, whereas the victim who is already disadvantaged by network latency now gets an additional penalty of the movement initiation being not telegraphed.

To solve this, the fog of war would need to use purely positional near-edge tolerances, which defeats the entire purpose of fog of war to begin with, which is the pre-aiming reaction time advantage of tracking the peeker through walls in addition to having a farther lever point from the cover than the peeker.

    > Does it cause pop-in when peeking?
    The goal is early reveal, not exact last-millisecond reveal.
    CS2FOW predicts using movement and ping, reveals enemies slightly before exact visibility, and keeps revealed enemies visible briefly. This intentionally leaks a small near-corner window to avoid late pop-in.

This fails to address the main point of the "pop-in" issue relevant to fog of war systems, which is that it is the victim of the peek that gets the worst pop-in effect, the peeker much less so. The aggressive peeker gets the benefit of the early-prediction from the server since they're the initiator of the movement, whereas the victim only begins to receive the information after the peeker has already gotten two network roundtrips worth of early prediction.

I wonder if this could all be solved if doors are triangles instead of quadrilaterals.

I like to think of it as dot product being the true "natural" space to compare magnitude metrics, whereas absolute value is just a human construct conceived for our mental convenience. A smooth parabolic bowl vs an unnatural sharp conical tip. Also shows up in standard deviation etc.

Aside: I wonder if complex values neural networks with activation function just being sum(inputs)*conj(sum(inputs)) with threshold normalized by sqrt(num_inputs) could be the most universal, where incoherent inputs will average an absolute value of sqrt(N) and coherent inputs are N like lasers? (square amplitude would be N vs N^2 between uncorrected and correlated population)

> Anthropic, Open AI & Co. realized at some point that if they can't make money with barely any competition they sure as hell won't if the market is flooded. So here they are slamming the door behind them.

Jokes on them, there won't be new entrants not because the door is shut but because it doesn't actually make money. The whole scheme is propped up by illusions to grift the investors, fewer competition only breaks the illusion. But I guess those folks aren't the types to understand "rising tide lifts all boats", or in this case, rising sewage buoys all rats.

If you would actually read the comment then you'd see the mention of in-place upgrades instead of complete reinstall. There is no drawback of hassle with in-place upgrades as everything on you system is kept as-is, and it takes about the same time as a typical windows cumulative update if not less due to pre-downloading the files.

And instead of unbased hypotheticals perhaps you can point to even a single example of normie software that check for editions of windows as a result of bad coding rather than user-hostile intent? To do so you'd need to go out of your way to hack together undocumented corners instead of the path of least resistance of calling GetVersion() as would be characteristic of lazy coding.

> you could run into issues with software that expects home/pro and not LTSC.

That's a laughably ignorant statement for how windows app development works. Raymond Chen weeps on reading your comment. Enterprise edition is a strict superset in functionality over Home/Pro, and LTSC just adds longer support.

Enterprise IoT just comes with Windows Store components sitting dormantly, which you can promptly activate with `wsreset -i` and it's then identical with consumer editions (other than TikTok and Candy Crush not being forcibly reinstalled after every "feature update") where you can install apps from the Windows Store as needed or just use winget instead.

Enterprise IoT LTSC is just Enterprise IoT with longer support.

There is literally and strictly no downside with using IoT LTSC, especially with the combination of official Rufus + MAS to install from official ISOs.

Actually, with MAS, you can also just download the IoT LTSC iso to perform an in-place upgrade that keeps all your existing Windows Store apps and program installs etc., just follow https://massgrave.dev/windows10_eol#upgrade-windows-10-home-...

You can just use the official iso with Rufus and MAS, no need to torrent sketchy backdoored versions.

> That's why you always normalize the quaternion first

Again, that won't solve the problem of floating point components not perfectly adding up to one.

Constantly normalizing quats are unnecessary performance hits and worsens your accuracy with no benefit other than being marginally "easier for low-math programmers to reason about", when you could instead just work with non-unit quats homogeneously and divide the final result with the quat square magnitude just once in the entire pipeline, or not at all and instead just pass the square magnitude as your w factor that gets divided on the GPU anyways

The formulas provided for quat to matrix and quat to axis angle is terrible, they only work if the quaternion's magnitude is exactly one. You need to replace sqrt(1 - a*a) assumptions with actual components, and use atan2 instead of acos. I don't blame the author though because the vast majority of info you can find in online learning materials uses this ill-advised formulation, including Wikipedia. But it's really trivial to realize this fact if you just go ahead and derive from the quat sandwich from first principles and realize that the "convenience simplification assuming unit quat" is actually an unnecessary step that have no benefits and are wholly detrimental when implementing them for floating point numbers.
