- Congratulations! This is incredibly well done. Please consider creating a “part ii” that expands on the entire thread to one level of greater detail.

It would be better without the editorializing.
by jibal - Nice article! Having little interactive examples I think is fantastic, and makes the text really utilize it's medium well.
The text was mostly a refresher for me who already knew the subject, but I would heartily recommend it to colleagues with less hardware know-how
by Warwolt - This is an absolutely fantastic article. I read the whole thing this morning and as a frontend dev it really makes me appreciate how cool all the tech I'm using actually is.
- Excellent overview to give footing to anyone hovering at the higher levels of abstraction like myself. The interactive diagrams helped make some concepts click that were trickier to grasp from previous readingsby marjipan200
- I liked this article. Richly illustrated and kept things interesting, even for a reader who is familiar with most of the material. Maybe too long for a single reading though, you might have better response by publishing in more digestable chunks. And I'd remove the AI messaging, it distracts from the main ideas.by lioeters

- I really like the diagrams! This is a great way to show what happens deep down. A lot of engineers I know have very poor understanding of how software actually works. However a couple of things: - Theres a lot of text and not all of it is valuable - Hijacking the browsers "back" button is kind of annoying.by accurrent
