sudo pacman -Syu base-devel devtools. This will pull in the necessary dependencies to build Arch packages.pkgctl repo clone --protocol=https linux. This will grab the PKGBUILD for thelinuxpackage. There should now be alinuxfolder in your current directory.- Visit https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=1c3366abdbe884 and download the patch by right-clicking the "patch" link next to the commit id and save as.

Patching Linux Kernel 6.8.2 to solve BT issues
Needed to remap keys on my ELECOM Huge Trackball, so I wrote a .conf file to be loaded at boot by X.
The ELECOM Huge has 12 keys you can assign. I will be remapping Fn1 and Fn2 which are near my index finger to be used as regular Left Click and Middle Click
| Code | Default Key | Remap Key |
|---|---|---|
| 1 | Left | Left |
| 2 | Middle | Middle |

Setting up "Watchdog" to keep Raspberry Pi Alive
We have deployed a couple of long-running Raspberry Pis equipped with cameras and sensors reporting into our network 24/7. All these are under uptime monitoring for us to keep track of the network availability.
From to time one of our Raspberry Pis freezes in the field either because of a kernel or a hardware issue. In that case there is nothing that can be done with software anymore. You can’t connect to it, can’t ping the Pi – It becomes impossible to send it a restart command in any way to bring it back to normal operation. Debugging into these events you might find indications of such as freeze in the /var/log/kernel.log file, and only manual powering down, and powering up again brought it back to live.
One little known Pi features is a builtin hardware watchdog. This little hardware service will once enabled watch the system activity and automatically power cycle the Raspberry Pi once it gets stuck.
It’s done in few steps directly on a terminal on your Pi:
- Enable the hardware watchdog on your Pi a

LINUX - Switch your main audio output to your headset when bluetooth connects
Depending on the distro or DE/WM you are running and which programs you are using to manage your audio you maybe run into the hassle of having to switch audio outputs each time you connect a bluetooth device (headset/speaker). You can in fact make pulseaudio to autoswitch when connection is established and not do it manually.
To accomplish this you just need to check a condition in the default.pa config file located in /etc/pulse/ directory on your install and add the following line load-module module-switch-on-connect like in the code snippet below:

Use different GTK themes for specific programs
Most common scenario, you installed a program that looks horrible or unreadable on your current theme or variation of that theme (light, dark). There's a simple workaround for most programs to fix this problem.

Export TOTP tokens from Authy
There is an increasing count of applications which use Authy for two-factor authentication. However many users who aren't using Authy, have their own authenticator setup up already and do not wish to use two applications for generating passwords.
Since I use 1Password for all of my password storing/generating needs, I was looking for a solution to use Authy passwords on that. I couldn't find any completely working solutions, however I stumbled upon a gist by Brian Hartvigsen. His post had a neat code with it to generate QR codes (beware, through Google) for you to use on your favorite authenticator.
His method is to extract the secret keys using Authy's Google Chrome app via Developer Tools. If this was not possible, I guess people would be reverse engineering the Android app or something like that. But when I tried that code, nothing appeared on the screen. My gues
