I think the problem with that idea is that there's no guarantee that the input to the compiler is going to be ideal. It might be that the programmer write something in a suboptimal or naive way (possibly expecting the compiler to take

Likewise, it makes me think of the Descolada virus from the Ender's Game sequels.

True, but as a heuristic I it is safe to say that if you'd use integer units to represent a quantity then you should use "fewer" rather than "less". That tends to capture the majority of cases for using "fewer

Same here. I think the reason it bugs me so much is because my mind views it as a type error: int fewer; float less; is how I tend to remember the distinction. (Fortunately in my family, my wife is the language nerd who first

Probably my favorite to read out loud that way is A Christmas Carol . Dickens originally wanted to be an actor, found fame as a writer instead, and brought the two passions together by ging public performances reading/reciting his st

I tend to view arXiv as mainly an aggregated repository of documents that would ordinarily be tech reports. It is accepted practice to cite tech reports when the paper author is aware of them and they are relevant. I don't really see

The "Sampling and Reconstruction" chapter from PBRT is also pretty good. The authors have placed the 1st-edition version online as a sample chapter: http://www.pbrt.org/chapters/pbrt_chapter7.pdf

> most computer-generated images are rendered as an average of point samples weighted according to estimated coverage of a square pixel This may be true in terms of the sheer amount of GPU rasterized imagery. I wrote the pixel filterin

I'd say usually better quality rather than definitely better quality. While the Lanczos filter is always superior to the box filter in theory, there are some case in practice where the box filter may be better. If you're down

You could also efficiently sieve down the list of candidates with a Bloom filter. Toss all the numbers into a Bloom filter, then scan through them again and cull any number, i, for which neither i-k nor i+k are present in the filter. Then r

It doesn't need to be that complicated at all. The book "Hacker's Delight" gives some nice, fairly simple implementations. Here's one: http://www.hackersdelight.org/hdcodetxt/hilbert/lams

It also depends very much the geometric complexity of your scene. With hundreds of millions of polygons it's not difficult for raytracing to outperform rasterization, especially if most of those polygons are instanced.

I've been planning lately on writing my own little 2d rasterizer for fun. While I really like the trapezoidal signed-area method, when reading STB's write-up I noticed that it can overestimate coverage when a path self-intersects

You can. For my programming font [0], I provide versions of it that bake in the output from Freetype's hint interpreter applied at different point sizes and display DPIs. This way platforms such as macOS that don't always apply

There actually is a first-party app from Google that can read QR codes: Google Goggles. Besides QR codes, I've also found it handy for scanning the ISBN bar codes of books that I want to remember.

Hmm. Downloading the current viz.js from the releases page (v1.4.1) gives me a file that compresses down to 632K when I use 7-zip on its highest settings (7z -mx=9 -mfb=258 -mpass=15 -tgzip a viz.js.gz viz.js).

It can indeed! Adapting the first example from the article, in Emacs type: M-x quick-calc RET integ(exp(-x^2),x) RET You'll see that it immediately responds back with: erf(x) sqrt(pi) / 2

Emacs' calc can also be surprisingly powerful. Not quite at the level of Maxima, but still perfectly capable of basic symbolic algebra and calculus, arbitrary precision arithmetic, linear algebra, and other good things. I use it quite

An important factor is whether it can be branch predicted. If the virtual call nearly always goes to the same method implementation (e.g., always an OpenGL renderer or always a DirectX renderer), it can actually be pretty cheap. They get

In the case of TrueType hinting with the interpreter, it can. The SCANTYPE instruction [1] allows the hint program to request different scan conversion settings. It's mainly used to change the dropout control mode. Without dropout c
