The Q&A Episode

I keep a list of frequently asked questions, related to Laracasts and being a programmer in general. In this episode, we'll breeze through a long list; everything from Jim Henson, to DHH, to facades! What music do you (Jeffrey) listen to when coding? Why not branch out and teach more subjects on Laracasts? Should I be using Laravel facades? Should I test every single class? Sublime, PHPStorm, or Vim? Why do developers disagree so much on best practices? Doesn't that defeat the purpose of a best practice?? Do you have any advice for first-time conference speakers? What do you do if you can't grok a particular coding concept? How do you refactor code, if you have no idea where to start? What theme do you use? Who are your personal, coding, and education heroes?
