Disclaimer : this is a "Quick gist", meaning I won't describe everything that happened precisely. I had a problem, found a solution, here it is

Cause :
Was on ArchLinux KDE 5.23.3 X11, went to Wayland then back to X11, and fonts seemed to be bigger, imgages and panel parts (like the app launcher) too

When creating a new user, they also had these weird settings. Not sure if caused by Wayland changing something system-wide or an recent update in KDE on new sessions

Resolution :
Managed god-know-how to get an user to have a smaller font+images+widgets size
File ~/.config/kdeglobals seems to manage KDE settings

"""
This script aims at converting an image to the custom format used by Remarkable 2
After running this script, move the output "splash.dat" file to /var/lib/uboot in the rM2 device
I tried this with PNG images but I guess other formats should work too since I use PIL
Syntax: ./main.py <file> [-x xOffset] [-y yOffset]
(-x and -y are the offsets of the image on the screen. If not set, the image will be centered on the screen)
Input images may need to be rotated 90 degrees before converting them

I recently spent an hour on Googl trying to figure out how to have a custom ID on an anchor, because titles like this

Hello I am a very long title. Why ? Because I wanted to

are quite annoying to reference then

What is what I learned : apparently, there's no way to do it in Github's markdown. There seems to have been a way to do it in the past using ### Some title {#custom-id}

NOTICE : This is a bonus chapter of the article (to understand header guards). If you are reading this by scrolling past the end of the article... Well you should not do this

Header guards

Now, let's imagine this example (notice I removed the mySecondClass object)

main.cpp

#include "myClass.h"
#include "myUtils.h"

// Simple program to simulate the `pause` command from Windows. Compile with `gcc -o pause pause.c`
// I'm ofc not going to put a licence on that, do whatever you want with it
#include "stdio.h"

int main(){
	
    printf("press any key to continue\n");
    getchar();
    return 0;
}

iTrooz

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#include <sys/msg.h>

int main(){
	char* buf = "Hello world !";
	unsigned long len = strlen(buf);
	char* buf2 = alloca(len);

There previously was a support page with the answer, but since Huawei removed it, here I go (I think it was https://consumer.huawei.com/en/support/content/en-us00692700/)

I had a issue with my ArchLinux KDE computer where sometimes (when I used cpupower-gui I think), my computer would enter a "mode" where charging the computer would reduce the frequency of every core to 400MHz The issue would then appear everywhere, even in the UEFI (and yes, the lag was noticable, even there)

From what I remember, here are the instruction that were on the Huawei support page : (computer on)

• plug the charging cable
• Shutdown the computer by force, by holding the power button for 10+ seconds (continue even when it's off !)
