• 4:08 My question is about empty sidebars on long "pages" (trying to get away form using that word). Many websites have a sidebar column floated to one side of the viewport, and once you scroll past the content in the sidebar it's empty space. Is there a good fix for this?
• 10:12 It seems that in webdev land, Mac is the king, Windows is a footnote, and Linux is the redheaded step-child that nobody talks about. What do you guys think about Linux as a developer environment?
• 19:27 So I have this... uh... friend... who's building a Rails app and he, I mean she, is wondering about Authentication. Rails has this gem called Devise and there's two standard plugins that aren't enabled by default: Confirmable and Lockable. Confirmable will send email confirmation to verify accounts. This seems pretty standard right? Lockable will lock out the account after a few failed attempts. Should she enable both of those?
• 26:32 How do you guys strike a balance between your personal and business brands across all social platforms? How do you decide if a tweet should be from your personal account or business account? When do you cross promote? Do your messages change across platforms? Do you simply repeat the same post on twitter, facebook, google+, etc or do you adjust your message based on the platform?
• 38:23 What do you think about employers willing to pay $20/hour or less with junior (front-end) developers? Does salary raise any red flags?
• 42:33 Have you ever used, or know of any existing tools that use JS automation to check things on a pre-launch checklist?
• 49:44 Is there a point that WP suffers a performance hit due to a large database?
