A bit C++ and game engine focused (to be expected since this is were this kind of techniques originate from), bit very good explanation on how to have packed layouts for your objects and reduce pressure on memory allocation for data intensive tasks.

Good thinking about abstraction levels on top of a platform. It's very much focused on the Web platform but applies more generally. Good food for thought on the libraries vs framework debate, why escape hatches matter and why you want a layered architecture.
