Riak-CS Pull the github repository; it has a Makefile and scripts to bring up the cluster and test it. It can set up a haproxy container in … Continue reading »

This past weekend I participated in my first Startup Weekend Columbus. During the course of which we built Fairflo, a marketplace for fair-trade items. The front end can use some work, but at the end of the weekend we had a fully functioning e-commerce site. I’ll write about the infrastructure separately, but as an aside … Continue...
