When we aren’t busy teaching bootcamps or building apps for our clients, we’re showing off our Nerdy prowess by getting involved in our community through our code retreats, tech talks and other events. Here’s a sampling of our recent Tech Talks, plus a bonus video from this summer that you may not have seen before.

First up is Big Nerd of the Month Stafford Brooke’s Tech Talk about using Ruby on Rails on Heroku.

And Matt Mathias recently led a Tech Talk on ReactiveCocoa.

And of course, I would be remiss if I didn’t include “Cocoa Got Blocks,” starring our very own Steve Sparks.
