You could also approach this from the other direction: our focus on productivity, efficiency, monetization, etc. prevent people from pursuing things they are interested in and developing skills that don't directly translate into profit.
I had a lot of niche interests as a kid that apparently make me interesting as an adult. All of them are because I grew up in a small Wisconsin river town with parents who worked in the arts. Lots of time, minimal media exposure, and plenty of freedom to just… putter, learn and make. As my dad would say back then, ‘only boring people get bored, go find something to do’.
eMMC usually has csd and ext_csd registers that tells information regarding wear level and such. It's easy to access these from Linux, but not sure how we would do it on Android.
You can build/install mmc-utils on the device (even from Google's repo,[1] if outdated) but can't access the storage device paths without root. If you're on a custom ROM, the mmc command might even be part of it.
That man is really good at teaching/explaining SI concepts. He was my professor at my university and taught High Speed PCB design class. Lots of learning like the one you described!
I remember I tried Yocto, indeed it’s customizable, but when I tested it, its performance wasn’t on par with the stock one, specifically with gstreamer and vp9 encoding/decoding. Maybe it’s changed now though, worth the try OP.
Basically, go watch every Rick Hartley video on YouTube. He is awesome at explaining. It will become intuitive instead of being a bunch of cargo cult advice. (Normally I dislike long videos but this is absolutely worth your time if you design PCBs.)
ADD: in short, it happens for "any" frequency. This is how a voltage signal propagates. However, for DC it happens once because you see "change" in voltage only once and that's it. As you increase the frequency, you'll end up seeing more voltage waves due to "change" in voltage. That's when "reflections" come into picture - happens due to discontinuity in impedance.
My guess would be that not a lot of people have done work to collect concrete data around it. Problems like these really go unnoticed, even most samples from urban-young crowd in India will say, "why do we need reservation?", "there's no caste discrimination".
