Student projects such as note-taking apps and PDF viewers

Are PDF viewers a common student project? I always assumed the file standard must be a labyrinthine mess given all the features they’ve crammed into it over the years. Or is there some popular library that takes 99% of the work out of it?

It looks like you can have a bit over 4,000 blocks/meters of verticality with a custom world.

I disagree when it comes to standardized single-letter variable names. They’re invaluable when writing dense code for games or other math-heavy applications and you learn to recognize them very quickly.

So i for index in loops (and j, k for nested loops, but you’re almost always doing something wrong if you need them); x, y, z for position and h, w for size; r, g, b, a for color data, etc - you’ll immediately know what the variable is for at a glance even though it’s a single character.

Another benefit is that having related variables be the same character width keeps code visually aligned, which helps with readability.
