The main problem with Hacker's Delight is its age. It has lots of bit tricks and optimization guidelines you'll find useful, but you have to understand that a big part of it doesn't apply on modern devices. But as long as you treat it as a collection of snippets and benchmark the code on modern devices (or, if you have built some intuition, that works too), it's an invaluable resource.
