increase inotify file watchers in manjaro

this issues shows there is another file called 50-max_user_watches.conf that overrides the 40-max_user_watches.conf that is in most of docs about increase file watchers
guard/listen#444

so, to fix, just add the same to both files:

echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/40-max-user-watches.conf && echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/50-max_user_watches.conf && sudo sysctl --system

[Manjaro?] KDE not changing default browser

Setting Chromium in default applications for browser keeps opening Firefox for links in other apps like Discord and Konsole.

Found that xdg keeps firefox

$ xdg-settings get default-web-browser
firefox

and the BROWSER variable keeps pointing to firefox too:

$ echo $BROWSER
/usr/bin/firefox

Need to change both:

$ xdg-settings set default-web-browser chromium.desktop // the .desktop extension is needed
$ echo "export BROWSER=/usr/bin/chromium" >> .bashrc
