“Your worst Nightmare” April 10, 2008

I have just spent a marathon session of trying to debug my code that is heavily laced with Quaternions. This 4 dimensional, real and imaginary numbers have plagued my dreams the last few nights. I have been fighting and fighting. Delving deep into code that someone who no longer works for us had written. He did things in a manner that was difficult to understand and follow. He chose not to comment. He wrote in "matlab"(shudder). He counted starting with the number 1! (as opposed to all sane programmers who count from zero).
And today, after going on a chocolate run for the Mission Planners (if the planners ain’t happy, nobody is happy), I found the source of my hell.
I couldn’t make a unit vector to save my life. Oy vey! I need a drink!
Sigh…
