"Calculated Ignorance" - be careful what you get good at...
Since my wife doesn't come here, let me share.
She has over 25 years experience in computing systems with over 18 as a UNIX system administrator. Currently, she is an upper manager for a not-to-be-named company. She manages business critical software applications for Forbes 500 companies.
I swear, right now she has over thirty applications running on her painfully slow and outdated pc. There is a brand new pc not 3 feet from her lying prominently on the piano waiting to replace the four year old overloaded pc – not!
Oh ya, she has multiple degrees in computer science and mechanical engineering
