If you're hosting a workshop and considering hosting JupyterHub to allow people to get hands on with code without the hassle+time sink of self-installation, I've put together a guide covering a self-hosted way to do this: https://fluids.rocks/posts/tljh/
I held a workshop for #pyrolite back in 2024 and tried doing this with a VPS but had a bunch of trouble getting a beefy node for the 40 odd people without having some history with the major cloud players (one even banned and deleted my account for 'suspicious activity' without explanation). Have been frustrated since, so glad to be able to demonstrate an alternative for where you do have some hardware lying around.
