i've never set a global variable except for one time during an interview when they asked about something and i just diarhea'd out 'global variable' and then was like "WAHAT"

class/instance/module-level mutable variables that could've been scoped to only be immutable function parameters are basically the same as global variables and i see this everywhere

dear terrible programmer thread, please try to talk me out of designing my own data structure or at least point me to where somebody has already made it the general idea is to combine list-compressing (i.e. "aaaaccb" to "4a2c1b") with the Yale encoding of sparse matrices this way when you have an array that has a LOT of repeated entries (the original inspiration was a minecraft world which has a few layers of rock, then dirt, then air but they're not uniform and need to be easily mutable) you compress them together and record the index where the repeated element begins: for example ____ ____ _... .... would be encoded as [(0,'_'), (9, '.')] Yale however caches a bunch of information to avoid having to constantly traverse the list though, for example rows 0, 1, and 2 all start in the 0th element of the list of pairs (i.e. start with a '_') and row 3 starts with a '.' so the row-start array would be [0,0,0,1]. Yale also caches the height of each element but I'm not sure if that'd be useful.

what do you actually want to do with this data structure? because if it's just storage, you may as well use an image compression library. if im remembering my web poo poo right, png's the one for images with large flat areas

if it's for storage but you also want to index into sub-arrays, HDF5's approach is to chunk the array and then store the gzip'd chunks in a b-tree.

I was playing minecraft and I was wondering how I'd implement that and it seemed like a decent project to learn f# in because it's inherently mutable plus it needs to generalise to 3d. I figured I'd try to implement morton ordering and maybe a visualiser after this
