A script to move my terminal window to/from my tablet when I leave/reenter the workspace, tmux + sway/i3
#!/usr/bin/env nix-shell
#!nix-shell -i python -p "python3.withPackages(ps: with ps; [ i3ipc ])"
# A script I've thrown together
# to use my tablet as a somewhat usable extra screen.
# The core idea is to ssh (mosh) to my work laptop,
# attach to a tmux session creating a new group (`tmux new-session -t tablet`)
# and then create a tmux binding to exchange windows between tablet and laptop
# (`bind Tab swap-window -t tablet`).

What is a monad, attempt 1 of several

Skippable intro

tazjin once told me something koanish in the lines of:

When a man 'understands' monads, he writes a blog post about it. And it takes three such posts for him to really understand monads.

This text is my first 'post' in this hypothetised progression. I anticipate missing the point, so the intended audience is not other neophytes, but seasoned FP folk looking at me condenscendingly before replying "you're not there yet".
