Hacker becomes a good guy! Can this possibly be true? A new, reformed Hacker runs for election against Motherboard, claiming to have done five good deeds, and promising to turn over a new leaf.

The Big Idea: When people use words like always, never, all, or none to claim something is true, be suspicious! Such claims are often false, and you need only a single counter example to disprove them. Math Topic: Counter Examples NCTM Link: Reasoning & Proof.
