Ask HN: How to fix difficult programming bugs?

I've read two articles on hn that blew my mind.

1. How I cut GTA Online loading times by 70% - https://news.ycombinator.com/item?id=26296339 2. Resolving an unsual WIFI issue - https://news.ycombinator.com/item?id=32524702

In each case, the authors went deep into the system using profilers, process debuggers and a bit of reverse engineering to solve these problem. Thing is, i'm a web developer and don't know how these things work. Is there a book or course where i could learn these skills?

Thank you.
