Code Golf - The Zen of Writing bad Code
summary
Live demo of concrete PowerShell tricks and the final score not rhetoric shows how to shrink real solutions on code.golf, using PowerShell 7 features and shell aliases to cut characters, replacing functions with scriptblock recursion, exploiting n++/++n behavior and pipeline assignment, and using numeric literal formats to win with a 47-character Collatz solution. Slides and terminal examples run on the code.golf site so code executes, errors appear, and the published recording is captured by Confreaks for replay.
