I do contracting for different companies who get too much work on their hands and a deadline on their ass, and it’s always a trip to see how amateurish some of their developers are.

Like who the fuck names a major variable ‘abc’ or ‘xyz’ !!!!

Also they clearly don’t know how to ask equivalence if statements as I got a chain of if else statements that were written like

if (decision>0 && decision<2)
//Code
else if (decision>1 && decision<3) ...etc

That the equivalence of sets isn't a relation is the dumbest aspect of mathematics I've encountered so far.
