iolbs3 | How does strafe jumping in video games work? | So I know that originally strafe jumping came from a bug in the Quake Engine, and it's why so many older games (CS, Quake 3, etc) have it. I also know the bug comes from the accelerate function, but I don't quite understand *how* it ends up building speed. Something with the wish direction getting combined with speed m... | Technology | explainlikeimfive | {

iop3au | How does 'brute forcing' work? | I've seen a lot of graphics showing how long it would take a hacker to brute force their way through a password.
