    a sphere is a plane folded in on itself, and spheres have no (one-dimensional) holes. but spheres do have a two-dimensional hole, which is basically a way of saying they’re hollow.

    a circle is a line folded in on itself, and circles have one (one-dimensional) hole.

    edit: the claim that circles and straws are homotopic is basically a fancy way of saying: “if you place a straw upright on a table and flatten it by smashing your hand down on it, you will end up with a circle.”














  • i love my 60% keyboard. i rebound the caps lock key to be a modifier key that swaps the functions of several keys on the keyboard. i basically have two keyboards stacked on top of each other that i can switch between at will. e.g., when caps lock is held: the number keys turn into Fn keys, WASD turns into the arrow keys, and N, M, < turn into the volume down, mute, and volume up keys, respectively.

    i also changed the rgb colors on the keyboard so this is all color coded in case i forget.
