Ah yes, this is the functional definition of the min/mean/max continuum, thanks! So does this have applications in statistics, and is it ever used to produce a distribution of random variables?

Where can I find Red Delicious varieties from back when they were considered good? I remembered them being fine/decent/whatever when I was a kid, and recently just out of curiosity bought some Red Delicious from a local grocery st

Ah, fascinating, I’ve never used Order Statistics. It doesn’t look exactly like what I was thinking, but there is also a continuum from min to median to max, similar to min to mean/sum to max. I’m not sure but I might guess that for th

Parent is suggesting that sleeping must be good on the macro level. That does imply that it must also be good for the animal, right? In order to statistically benefit the population, the benefits to any given animal must statistically outwe

So I’m still left curious which debuggers are much better than VS? What do you mean about so slow there are semantic implications? How does execution speed change meaning? Can you give an example? And are you talking about VS specifically,

I don’t like working in Visual Studio much, and I am a big fan of gdb too (and of Chrome’s debugger when working in JavaScript), but for C++ debugging, the Visual Studio debugger is excellent, and has been near the top of the class for a lo

I maybe erred on the side of supportive as well, for the same reason, some perceived lack of support as kids. My parents weren’t entirely unsupportive, but I’d wanted a little more support at times and all the parents around me at the time

Why is that interesting to you? Do you have a contrasting point of view to share? Do you have experience with startups and/or venture capital? I have no involvement with YC, but with a little startup and VC pitching experience, I can t

Why are you bringing up Godot again? Are you worried Godot will be left behind or unable to compete with Unity? Are you working on Godot? Why are you focused exclusively on games? What are the ‘false promises’ of WebGPU, and why do you thin

It seems like you’ve jumped to and are stuck on a conclusion that isn’t really supported, somewhat ignoring people from multiple companies in this thread who are actively using WebGPU, and it’s not clear what you want to have happen or why.

by dahart 2y ago
I’m still not sure what the point is. WebGPU is an API, is that that you mean by middleware? What’s the issue? Apple will do their own thing, and they might not allow WebGPU on Safari. What bearing does that have on what people using Linux,

For that matter, why would you expose your CPU to a website? Or your monitor? It could show you anything ! ;) Maybe you are not be aware of the number of good web apps that use some WebGL under the hood? You might be using office applicati

Oh there are lots more axes than just the 3 aliasing, sharpness, and locality ones. Those are the main tradeoffs for a pixel sampling or convolution filter choice, when downscaling an image, say between nearest neighbor vs bilinear vs Mitch

I don’t quite understand where this is going nor why. This little sub-thread stemmed from a good tool that does already exist, and from unsubstantiated claims that C devs are students and that the simple build steps are too hard for most pe

There’s probably a way to get a stable conservative error bound for a parallel sum reduction that’s non-deterministic. Here’s the PBR book’s chapter on error analysis. It’s way easier to implement error bound tracking than it is to come up

The Higham book does work toward error analysis of matrix multiplies, it would be useful to see how that’s done. In the case of autodiff, you do presumably know the exact computations that are done, there just might be so many of them that

Just to pick some nits with those claims… CPUs do have hardware support for functions in the form of a stack and CALL/RET instructions. Functions are a useful abstraction since more or less all software uses them. Functions and functio

Come and visit makes it sound like they traveled to be there, where just visit might be the neighbor stopping by. It’s subtle and ambiguous, but I do see valid use for come and visit.
