How do non-software engineers feel upon reflection, about their degrees? (ycombinator.com)
To set the scene: I wanted to build my own devboard for my own projects. I'm sat here looking at my screen after having opened KiCAD with some of the documentation for an STM32H7 MCU. It dawns on me that I have absolutely zero clue of what I am looking at and have no idea where to start beyond watching youtube. Here I am now writing this.

Why Books Donʼt Work (andymatuschak.org)
Books are easy to take for granted. Not any specific book, I mean: the form of a book. Paper or pixels—it hardly matters. Words in lines on pages in chapters. And at least for non-fiction books, one implied assumption at the foundation: people absorb knowledge by reading sentences. This last idea so invisibly defines the medium that it’s hard not to take for granted, which is a shame because, as we’ll see, it’s quite mistaken.
