It's Afternoon at Isotope a.k.a., one GC member's write-up about about #terngame 2013. I don't know how coherent it is, but by golly if I don't write it down now, I bet that this week's going to expunge it from my memory. They say "write what you know" but that only works if you don't forget. Mostly what I want to remember: some needed tweaks to the answer-checker app. I don't know how interesting that part is to anyone but me, but I threw it in anyhow, before I forgot.
