I’m not deeply familiar with either, though I have written a toy x86_64 bootloader once. There are more levels in x86_64 (which makes sense to me that a larger address space would benefit from a sparser encoding). What else is significantly

There’s so much numerology in the world, even among smart people, that I think this is worth being pedantic about: There’s no such thing as a “four-digit number”, only a four-digit base-10 numeral . And facts about base-10 numerals aren’t

The point about gamma correction is important. Many effects like scaling and blurring should occur in what's called linear color space, otherwise you add or remove energy, which can look very wrong. Normal RGB isn't linear. GPUs a

It’s not irrational: an ETF would make it a lot easier to buy Bitcoin, which would increase demand. It’s funny though, because if Bitcoin would work as well as advertised, a traditional exchange shouldn’t offer this kind of advantage.

You might be right, but they don’t turn smoothly, so I’m not entirely sure. The ball is definitely a sprite, it always faces the same direction.

Solvers aren't magic. But it turns out that many naturally occurring instances of NP-hard problems aren't the "really hard" instances that the NP-hardness proof depends on. Solvers can also fail for really tiny problems.

A problem is NP hard if there are instances that other hard problems reduce to. That is, only some instances of the problem have to be hard. NP hardness says nothing about "average" problem instances and even less about hand-pic
