Markdown supports images and tables. It may depend on the rendered though. The GitHub flavour of Markdown supports this for example and I expect Latex supports it too. If existing tools don’t exist to get the height of elements you can probably make it yourself fairly easily if you you the specific font and styling the renderer uses. You’d just have to parse the file, which is basically plain text, and run the same calculations the renderer would. For which approximation might be fine depending on the use case

This is very different from docz or odt, but maybe its worth looking into converting markdown or latex to PDF with something like pandoc. Maybe that or some other more open and less complex format might help with this?

Hetzner storage boxes look really compelling. Thanks for sharing!

Cloudflare tunnels definitely aren’t wrong, you’re just not entirely using open source software. It’s a very good option if you need to open things to the public or want to learn more about cloud services

You can selfhosted tailscale so that they don’t have any access. You can’t with cloudflare tunnels as far as I know. Tailscale’s client is open source, so is their Headscale server which originally was developed by a 3rd party. You can look into the code for that. Not sure what you’d want me to say. If you really want to be informed I’d inspect the code yourself

Tailscale shouldn’t be getting your data anyway. It’s a mesh VPN that directly connects devices after their auth server gives out certs and let’s clients know where to find another. If you’re not comfortable with using their server for this I’d suggest you look into the open source headscale server. I do remember it routing through their server in the rare case NAT punching doesn’t work

Personally I use tailscale which should punch through double NAT. It’s a wire guard based mesh VPN, but an exit node should make it a normal VPN

You can use headscale with tailscale if you want to self host it. Headscale is a community made server implementation for tailscale

I run wiki.js for documentation for my home lab, but also things like the custom rom setup for my phone. However it’s hard to keep it up to date as I forget it exists. I mostly use it to document setting up windows server core with different roles as I don’t need to do that often, but most tutorials on the web are SEO optimised with low quality

This video from thiojoe is probably relevant here. It is mostly for scam websites, but maybe it’s useful for this too? At least gives you some platforms to contact
