Yes, I am aware it has been 'superseded' but in my experience for lossless compression it's still usually better.

You could still stream the pixels, you'd just have to stream them in Z order. This may seem pedantic, but this applies to any mismatch between the order in which you store pixels and the order in which the format stores pixels. E.g. so

Copying the question text verbatim certainly is copyright infringement (and I would guess unlikely to be fair use, but I'm not a lawyer). If you give the problem in your own words, it won't be, just like your solution isn't

I don't know, only have some theories. 1. The name isn't particularly catchy or descriptive. It is the correct name for the data structure, but not too many people know the data structure. 2. People don't even know what they&

SlotMap literally cannot, because it must keep track of versions of the used slots, and the slots include the memory space for the data. DenseSlotMap sort of can. It still can't reclaim the memory used by empty slots for the same reaso

There is no fragmentation whatsoever in the traditional sense (unusable gaps left due to size mismatches), because a slotmap only stores a single type of value. Thus every slot is interchangeable and memory can always be reused. For iterati

If a significant amount of your new customers find your physical shop through Google maps, what can you do? If someone wants to find a hardware store near them, good chance they'll just write "hardware store" on Google maps.

I did miss that, oops. That said, it's again unclear if that curve is pre- or post- biased sampling. If it is on the original data it is quite good, but with a heavy biased sample fairly meaningless.

Very sloppy statistics. A lot of explanatory analysis on the model is done but the model is hardly justified in being predictive in the first place. The paper ( https://journals.plos.org/plosone/article?id=10.1371/j

No, it is a Pokémon reference to the very similarly named Excadrill.

Softball is a bigger ball, yes. But it's not lower velocity, at least if you consider the relevant metric: time from pitcher to plate. Because softball also pitches a lot closer to the plate.

From what I have read (I don't do 3D modeling myself) Blender has overhauled its UI significantly over the past couple of years to great praise of a lot of people.

I would guess that India is too large to meaningfully include in such a statistic. On average in the country English literacy could be quite poor while in the relevant tech hubs it is quite good. But that's just a hypothesis.

Rust sidesteps issues like this entirely through its Editions. Code from different editions can all each other, but editions can introduce breaking changes. For example, in Rust 2018 and earlier calling arr.into_iter() on an array type woul

PNG is lossless, so it really does.

Here in the Netherlands it's the exact opposite. We have infinite water, just not a lot of space.

You are completely wrong about ? in my opinion. Between it, built-in load carrying tagged enums (also known as sum types) and the built-in Result and Option types, they essentially solve the exception problem while still being entirely expl

Experimental science is all based around ruling out the null hypothesis. For that it needs to be falsifiable . The hypothesis 'the dog can differentiate between A and B' is very hard to falsify. Because the dog could differenti

I think the idea behind Nuitka is to compile Python into an executable, rather than interpret a script using a fully generic interpreter, but without (or with minimal) limitations, falling back to libpython's implementation if necess
