> My router assigns dynamic IP addresses, meaning my server location kept changing. I've had a similar problem in the past. It turns out that most routers have a way to assign an IP address statically based on the MAC address of the requesting device without affecting the other DHCP devices on the network. I do this for my pi-hole, my NAS and my gaming PC.

As long as that's on the router's side. I guess I did that on my phone for some reason so when I upgraded and migrated they had the same address. I'm surprised it worked at all. It was just painfully slow.

Earlier quoted context omitted.

I have something similar that I built a long while ago. It's a large Do Not Disturb sign. There is a raspberry pi mini that controls power going to it. There is a corresponding daemon running on a PC that checks Discord call status. In call? Power to sign. Not in call? No power to sign. The client/server daemons are in Golang and communicate over RPC.

What does the pi do? Feels like something that could get replaced with an ESP32 if it needs to be remote or just an ftdi chip or some other usb to gpio if not

It's what I had in the drawer.

why does the site keep upvoting trivial projects especially derivative projects of what people seem to reinvent every few months. No offence to OP. I don't really get the site. Like, you have posts where someone runs doom or an OS in a PDF file that get 1000 upvotes which I think is valid. Then we get something like "I made an echo server" which is like someone copypasted code from an asyncio documentation page and p…

Many people at different parts of their technology journey . I like seeing these "redone" projects because it shows new generations of hackers following the path.
