Tried moving my Documents/Desktop/Music/etc folders to a Google Drive mounted via Drive File Stream. Seemed to work well at first, but after the first reboot Windows clearly wasn’t happy and kept complaining about not finding the Desktop or the Documents…
Possibly because that drive seems to be mounted a bit too slowly (i.e. happens a bit after one has logged in)? And/or because it’s just mounted in a way Windows doesn’t like?
When connecting my headphones via a simple USB-plug, the audio levels are often way, way, too loud. Today I had to turn the volume all the way down to 2% for the audio just to be OK’ish. That’s not very usable, and also kind of scary…
Open up “C:\Program Files\EqualizerAPO\config\config.txt”
Replace its contents with:
Preamp: -30 dB
And adjust that level as necessary…
Now I can finally use the volume bar in Windows, and the volume media keys on my keyboard properly. And no longer do I need to be afraid of suddenly having my eardrums shattered if the audio were to move a percentage or two… or, even worse, reset to max…
Needed to convert several SVGs to PNG, and discovered the free Inkscape easily can be used in batch scripts.
The following .bat file will convert all SVGs dropped on it to a PNG with height 48 placed next to the original SVG. More options can be found in the Inkscape manual.

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the

Revocation certificate created.
Please move it to a medium which you can hide away; if Mallory gets
access to this certificate he can use it to make your key unusable.
It is smart to print this certificate and store it away, just incase
your media become unreadable. But have some caution: The print system of
your machine might store the data and make it available to others!
