at 1 you are doing forward declaration.
you declare the interface of a function in the header file. that way the compiler would know that function swap exists and it takes two int pointers but returns nothing.
from the outside of that module that’s all it needs to know. it can compile them separately and link them together later dynamically.
you’re separating swap interface in the header file from its implementation in the .c file that contains the body of the function.
unfortunately it would probably just replace the context menu key. which I’ve already set it to keyboard layout switch. 😁 it’s the best keybind I have. way faster than mod+space or alt+shift 😅
I’m pretty sure most of these comments are written by programmers 🤣 reciting CSI stuff…
as an i3wm user, I approve 😁
lightweight media server Super fast indexing. Smooth web client. Also supports the subsonic api. I’ve been using the web client locally for some years now. I can also access my library on the go with substreamer on Android which is great. https://github.com/epoupon/lms
given that you’re looking at vpns I’m assuming you can’t do port forwarding on your network. Am I right?
Have you seen zerotier? it lets you create a virtual network. super easy to setup but in the default configuration you’re relying on a third party service. not sure if that’s ok with you.
The most user-friendly way to do it is hosting it on a https server. for this you need a reverse proxy. checkout caddy. or if you’re on docker try traefik.
Most home isps don’t let you open port 80 and 443 so you have to use alternative ports which is ok for https but it will make renewing certificates really hard. you have to do it with dns. if it works great. but in my experience it was usually finicky.
A cheap android box + armbianOs is also an option if you’re looking for low power. I have a 7watt one that’s running 24/7 for the last few years.
not exactly what you want. but check out gaming on whales Wolf docs. it’s configured for gpu accelerated X11 apps on docker. if I recall correctly one of the documents explained settings up nvidia drivers on docker completely.
I know you want an upgrade over rPi but If you want a cheaper option, you can buy an android box and install linux on it. most of them have unlocked bootloaders. you can usually find a ready to use .iso on Armbian community forums by searching the SOC model there.
Personally I run a 5$ android box. it has a quad core cpu + 2GB of ram. I use it for hosting my music library on an external hdd and streaming 1080p video. I also set it as my vpn gateway. It’s enough for my use case so I didn’t upgrade it.
In case this is a compositor issue, there is a keybind on KDE that lets you toggle it off. Easier than switching it in the settings every time.
