I've done something along these lines with a very simple DNS and DHCP server implementation as an Arduino library: https://github.com/pkulchenko/DHCPLite/. It is fairly short and while I don't claim it being fully correct, it was tested with different clients successfully; it was great learning experience.

#23I love all the series about writing your own X in 100 lines of code. It gives you the understanding of technology and removes a lot of unnecessary details. The great examples of this are 'A from-scratch tour of Bitcoin in Python' https://karpathy.github.io/2021/06/21/blockchain/ and 'Let's build GPT: from scratch, in code, spelled out' https://youtu.be/kCc8FmEb1nY from Andrej Karpathy I wonder if anybody tried to col…
Another one: Write yourself a Git: https://wyag.thb.lt/
I've enjoyed doing stuff like this myself. I wrote an IP stack up to being able to ping an IP address. I had learnt all of this in university, but doing it myself really cemented the knowledge. Using a notebook and doing literate programming is a must. I pretend that I'm teaching someone else, even though I don't plan on ever sharing it really.

Bocker is in this same category...docker clone in bash that's helpful in seeing what's really happening underneath with nsenter, namespaces, network bridging, cgroups, etc.

That is an excellent website. Thank you for bringing my attention to it

The cute hand-drawn aesthetic reminded me of fun times reading Forrest Mims' electronics books.

#27I host a pi-hole instance in the cloud. It's only accessible to my Tailscale network, which means that I can't reach it on my TV - unless I write a DNS proxy. Maybe this'll be enough to get my ass in gear and actually write it for once.

#29Earlier quoted context omitted.
What about a Pi that connects to Tailscale and have your TV work via that? https://tailscale.com/kb/1019/subnets/
That would mean getting a Pi, which I don't have...
Setting the pi-hole as your DNS server in your router would not work? TV should then use this DNS server after getting an IP-address via DHCP.

#30To be clear it's a DNS resolver, i.e. the client.
