I enjoyed working with Rails given that it was what I was studying before diving headfirst into all the frontend tech. at NSS (after which we'll do Node.JS); I'd hoped that I'd be able to remember enough to be useful, and ultimately, I was! I made the layout & buttons that appear when you click one of the four main buttons or "view subcategories"-- basically, wherever you see the blue boxes that grow a bit when you hover over them.
The big learning experiences for me were getting all the gems installed, working with postgresql and using git for a project with this many contributors. These were all pretty new to me and definitely things that I need to get familiar with. I also wrote html.erb files for the first time in quite a while, which took some time to remember but was ultimately quite straightforward.
Had a great time! The winner of the event was a virtual-reality psychedelic unicycle game. Which, I mean, was inevitable from the moment it was announced. Also its presentation was fantastic-- I don't remember the gentleman's name, but he had a Jobs-esque way of making me feel that I needed his product in my life.
