This is the kind of website that needs to come back! No "cookies bs", ads everywhere, "plz sign up to my mailing list", "share your location", "comment where are you from", "buy my ebook", subscribe, share.

I've recently come across a language learning website that was nothing but HTML and a very light bit of CSS. It was beautiful.

Great article.

Wish list of topics to add:

- branch predictors that can detect patterns (edit: I guess it's already covered in the paragraph about raising prediction accuracy)

- LRU-approximations in L1 caches

- Data prefetching (sequential, stride)

- Return address stack

Concerning μops, I think the 68060 did that, too.
