My Unreal project right now:
FVector
std::vector
Eigen::Vector
KDL::Vector
....
*sigh*
And people ask me why I like Lisp. A Vector is a Vector goddamit! Half my project is now just parsing the same variable to the different functions. sigh....I hate this.

So a little bit explanation to my last fuck rant

I was trying to make a cuda code faster, specifically eigen value decomposition for 12 by 12 matrices. For a week a made a fast and accurate version and a faster but less accurate version, both are faster than cuda. Then I was thinking about how to make the faster version more accurate.

Then we had this idea of using power iterations. And honestly I hoped it won’t work. But then, fuck me it worked, which means I had more work to do.

But hey, at least now I’m way faster than cuda on this

co worker edits front end to design, breaks code then files a bug ticket for you.

The c++ 'Eigen' library. It is by far the best library if you're in need of maths constructs, speed wise. And the only maths library that has an API that isn't a pain to use.
