I've got f-all in formal education for >INFORMATION< technology.
My background is military electronics (RF systems) and automotive systems. Somehow (dumb luck and being a computer geek/hobbyist for decades) I landed a sysadmin position.
I don't leave default passwords set on systems. My kids don't either, hell, my 8 y/o can tell you what a botnet is (albeit in rather broad strokes).
