All my personal stuff is currently on a Vultr VPS with 1 vCPU, 2GB RAM, and 55GB of disk space, for about £10/month.
I can't actually get OVH to offer me something that small, but a 4-core VPS with 8GB RAM and 75GB disk for £6.76/month.

it's happened again! Someone sent me "a file of 40 multiple choice questions to import into Numbas".
It was 40 iterations of "placeholder question about X", each with options literally "Option A/B/C/D", but with seemingly randomly-chosen true/false values, in a made-up JSON format.
I asked […]

@christianp Kepler's answer is this one: https://mathworld.wolfram.com/KeplersMonsters.html
Kepler's Monsters -- from Wolfram MathWorld
In Kepler's 1619 book Harmonice Mundi on tilings, he discussed a tiling built with pentagons, pentagrams, decagons, and "fused decagon pairs." He also called them "monsters." This tiling inspired Penrose tiles in 1973.

@robinhouston I saw it, but someone else replied in more detail so I forgot to reply to you.
`compgen -c` will complete a command name, but I want something that, for example, will complete `git lo` to `git log`.

@mike no, I want argument completion too!
I think of, for example, `rm *.txt` as a 'command'. I now realise that 'command' has a specific meaning for bash.
