macaulay2 internals part 1: repl startup

i'm back! ^^ long time no see!! x3

of a necklace's glimmer,
jagged in my eyes.
she glances back,
a strange assemblage of shapes
betraying nothing.

hey i guess

^-^ hiiii

this is a new blog. where i'm gonna write about stuff.

my background is in math, but i'm currently working on learning how to do embedded development and compilers. hopefully i'll also get latex support up, and i can write some posts on basic representation theory and algebraic geometry as well.
