Recently i bought a zuoya gmk67 keyboard, it doesn't have a function keys row and has a knob for volume control. Unfortunately, if you plug your gmk67 in a archlinux machine you will notice that using fn+1 will not produce f1 as expected, it will produce a screen brightness decrease, and if you change the physical switch in the back for the macOS mode, the function keys now work, but the modifier keys don't, quite stressful.

Fear not, you can either alter your system configuration so the keyboard functions normally, as in this gist, or remap the keys, as seen in the gist Using GMK67 keyboard in linux with key remaps!.

For this gist we are going to alter the configuration for the apple hid driver on archlinux, since this keyboard uses it, and alter the functionality of the Fn key.

This is tested on archlinux, for any other distro you might have to figure out yourself the correponding commands!

WSA or Windows Subsystem for Android is a Tool that allows Windows to run Android Apps directly without using any emulator. The problem is Windows Subsystem for Android is currently only available through preview via the Beta Channel of the Windows Insider Program. But if you follow this guide, you don't have to be in Windows Insider Program to try it out. The only thing you need is Windows 11 installed and some patience.

• A Device with any version and Edition of Windows 11 installed.
• Internet Connection.
• Hyper-V enabled.

pihole comes with it's own lightweight DNS server called FTL. It's geared towards easy of use. Even so, setting up this feature can be hard. Here are some lessons I've learned.

In this example:

• Your network is setup on 192.168.1.0/24
• 192.168.1.1 is your DHCP server and IP gateway. (usually your router)
• 192.168.1.254 is the host running pi-hole
