The CircuitLab founder https://news.ycombinator.com/user?id=compumike has written an excellent book https://ultimateelectronicsbook.com/

That’s me! Definitely a slow work in progress… Thank you for the kind words of encouragement :)

Unless you’re doing specialized physics, in the electronics world we always talk in terms of current flow – never electron flow.

Rather weird line from the site. My entire training and career have dealt with things from an electron flow perspective and it made understanding nearly every electronics concept easier. If you base your concept of electricity on positive current flow (remembering the words positive and negative are just labels), it makes understanding things like cathode ray tubes much more difficult.

That's weird. Every ECE course I took talked about current flow. We only ever touched on electrons when the physical process of doping a semiconductor was discussed. Cathode ray tubes were covered in physics class.

But yeah, when you're manipulating a beam of electrons, keeping track of how many electrons on which plate makes a lot of sense, but that seems to be limit case where the "current of holes" model breaks down.

What country did you train in? In my EE education, everything was about current, not electrons. EEs don't normally care about electrons, they care about the flow of charge.

I've done college, undergrad, and post-grad to PhD in EEE and they always define current as positive charge flow rather then electron flow.
