Welcome to the world of dynamically linked libraries and all the fun involved in predicting - and then manipulating - which libraries your binaries see and use ... all so you can get the results and performance you expect.

Dr Stephen Sachs from our performance engineering team lives in this world every day, and gave up a bunch of his time to help the Tech Shorts community understand how to use all these tools.

Part 1: readelf, nm, strings, ldd, objdump
Part 2: static vs dynamic linking
Part 3: RPATH and RUNPATH - manipulating which libraries your executable sees.
Part 4: let's hack a binary to show you how this all works in practice.
