My Software as a Service failed. After three years of running College Conductor, I’m shutting it down.

This is a chance for me to reflect, and give you some ideas of what pitfalls can happen if you’re planning to build a SaaS.

In this episode, we started a brand new project! I had some internet troubles so this “stream” is actually a local recording from my computer.

In this episode, we got into a static files problem that caused a template to fail to load from the Shiv app. After some serious spelunking through the Django code and deep debugging, we found the file permission error that was the source of the problem.
