A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

It's great to see that a national research evaluation organization, the Finnish Publication Forum (JUFO), has rated @joss-openjournals.bsky.social as level 1, recognizing its scholarly value

types of terminal programs

wizardzines.com/comics/types...

sometimes annoying things happen in the terminal:

why doesn’t Ctrl+C quit??
why can’t I select text?

these things aren’t random: different “types” of programs have different conventions for how you interact with them!

here are some categories of programs & their conventions!
1. REPLs

(python3, your shell)
you type code, press Enter and it runs the code

rules:

quit with Ctrl+D (only works on an empty line)
usually you have a million keyboard shortcuts for editing text
usually there’s history

2. full screen “TUI”s

(less, htop, ncdu, lazygit, mtr)

rules:

quit with q (usually)
you can often navigate with arrow keys
often ? will open the help
to select text with the mouse, press Shift

3. noninteractive programs

or slightly interactive
(grep, git, sort, scp)

you start it, maybe it asks you a question or two, it does stuff, and it exits

rules:

quit with Ctrl+C

4. wrappers

(ssh, env, tmux, rlwrap, unbuffer)
these wrap other terminal programs in some way

rules:

when the program(s) they’re wrapping exits, they exit

5. other

lots of things don’t fit info these 4 categories: text editors, games, email clients, IRC clients, …

rules:

I avoid these unless (like with vim) I’ve made a special effort to learn the program
