Back in the day "what happens when the user types a url in the address bar and press enter" used to be an interview question, and I remember nobody has ever mentioned the hardware and keyboard keys and interrupts. This post does! Pretty awesome detailed view of a request lifecycle.
- Carrok 2mo agoI still like this question because of exactly what you mentioned. What the interviewee does and does not mention can give you a fair bit of insight into their priors.
- Sesse__ 2mo agoI once got that question, started with the keyboard switches and the interrupts, and the interviewer sighed and asked me to get to the stuff in the browser.

Right at the end we’re talking about updating the DOM and rendering… there’s a whole Unicode and font stack and rasterization process happening in there.
