Exactly. To me he mistakes concepts like page ranking (which I think are much more akin to heuristics) with the purely mathematical concept of computation.

Probably there are a lot of heuristics in page ranking now, but it began life as an eigenvalue problem [1].

Not all books are created equal. I'm not the fastest reader, but if I can read a novel in a week or so by just reading 1-2 hours a night. Mathematics texts on the other hand may require as much as 1-2 hours for 1-2 pages (depending on how dense it is). CS texts tend to fall somewhere in the middle for me, but there's a reason that science courses tend to cover half of a book in a semester.

I'd start with an algorithms course, then progress deeper into Complexity theory. Perhaps a bit of discrete mathematics depending on your background.

I find that marking my place with "ma" and returning to it with "'a" is a huge productivity boost. Of course the "a" is just a label, you can use any character (this allows multiple marks as well).

if you only browse code use gi, that saves me a ton of time. gi brings you back to last inserted text.
