back engineer

An *ultra boss-level nerd that can unlicense, break, and optionally repurpose software (and/or hardware) that other nerds made.
The nerdness level of the product creators shall not matter to the back engineer; it is considered pwnable by the back engineer, whether the soft/hardware in question was shipped by basic low-tier/mediocre nerds, or by their superior mega-nerds and the like - the back engineer will unpack and dissect it with as least effort as required, because efficiency.

The back engineer may enjoy the following (not necessarily in that order): writing better code than u and ur dad combined, shitty memes, repurposing products, occasionally making stuff crash, caffeine, and/or gaining unfair advantage while learning new curse words from other players online.

Since we know back engineers are better programmers than most qualified nerds, they are known to ship highly stable and robust shit that will may very likely wreck other nerds' life's, turning them very dark and miserable, if those happen to attempt to back engineer the already-back-engineered shit themselves.

* ultra-boss = the very final ranking a nerd could possibly achieve in a single lifespan

- We can't go sleep now, we got some back engineering work to do.
- So what if you don't publish the source? They will just back engineer it.
- f*ck this shit imma back engineer that ass

Euphoria (Engine)

Created by NaturalMotion, Euphoria is a game engine that creates animation "on the fly" by using a skeletal-muscle system and a collision model, the AI that controls this "ragdoll" is aware of his surroundings and has an underlying sense of self-preservation. Used by Rockstar Games in their games (Eg. Grand Theft Auto IV, Red Dead Redemption, Max Payne 3.) Every reaction is different as it runs on a GPU instead of premade animations, characters will grab their wounds if shot, try to shield themselves from oncoming projectiles or walls, try and find a comfortable position when on the floor, grab things and other people and flail when falling.

Person 1: "Wow this euphoria (Engine) is great!"
Person 2: "I know! Why dont more companies use it!"
Person 1: "Too expensive."
