I'm using 1GB with TWM, DIllo, TUI tools, XTerm, MuPDF and the like. As most tools are small from https://t3x.org, https://luxferre.top and https://howerj.github.io/subleq.htm with EForth, (and I try to use cparser instead of) clang, my requeriments are really tiny.

You can achieve a lot by learning Klong and reading the intro on statistics. And xargs to paralelize stuff. Oh, and vidir to edit directories at crazy speeds with any editor, even nano or gedit if you like them.
