I use the ReVanced version of YouTube Music (no ads, high quality music). If I find a song that I like, I download it in FLAC format from one of the sites in the megathread
You seem to like the lines-of-code metric. There are many lines of GNU code in a typical Linux distribution. You seem to suggest that (more LOC) == (more important). However, I submit to you that raw LOC numbers do not directly correlate with importance. I would suggest that clock cycles spent on code is a better metric. For example, if my system spends 90% of its time executing XFree86 code, XFree86 is probably the single most important collection of code on my system. Even if I loaded ten times as many lines of useless bloatware on my system and I never excuted that bloatware, it certainly isn’t more important code than XFree86. Obviously, this metric isn’t perfect either, but LOC really, really sucks. Please refrain from using it ever again in supporting any argument.
With your solution using a diode on each voltage source, would there be any risk of a trickle charge draining the battery unexpectedly if the battery?
Current flows from high to low voltage, but the battery is at a lower voltage than the supply. Check the diode’s datasheet for the reverse current at the voltage that would be across it. It should be negligible
