I skimmed the article and agree with it at a high level, though I haven't faced most of those problems personally. I have several gripes with NumPy, or more broadly the notion of using Python to call a C/asm library that vectorize

I agree very much with what you wrote. > the lack of any form of pattern matching for control flow Growing features after the fact is hard. Look at the monumental effort to get generics into Go. Look at how even though Python 3.10 introd

The problem is that after calling scanf(), the number of variables that are defined is a variable number. For example: int x, y, z; int n = scanf("%d %d %d", &x, &y, &z); At compile time, you can make no i

> The compiler has no way of knowing that the memory would be undefined Yes it would. -fsanitize=address does a bunch of instrumentation - it allocates shadow memory to keep track of what main memory is defined, and it checks every read

Any sane language would design a list iterator to follow the order of the list. No, the difference is when you're iterating over orderless hash-based sets or maps/dictionaries. Many languages choose to leave the iteration order un

You can pay for those features in debug mode or in chaos monkey mode. It's okay to continue to not pay for them in release mode. Heck, Rust has this approach when it comes to handling integer overflow - fully checked in debug mode, sil

Agreed. The fact that a pixel is an infinitely small point sample - and not a square with area - is something that Monty explained in his demo too: https://youtu.be/cIQ9IXSUzuM?t=484

It's not a unit of information. How many bytes does a 320×240 image take? You don't know until you specify the pixel bit depth in bpp (bits per pixel).

Never mind anamorphic DVDs, all of them use non-square pixels. The resolution of DVD is 720×480 pixels (or squared pixels, referring back to the article); this is a 3:2 ratio of pixel quantities on the horizontal vs. vertical axes. But the

Or the fact that a 1 megapixel camera (counting each color-filtered sensing element as a pixel) generates less information than a 1 megapixel monitor (counting each RGB triad as a pixel) can display.

The site specifies a base font size of 12px. The better practice is to not specify a base font size at all, just taking it from the user's web browser instead. Then, the web designer should specify every other font size and box dimensi
