55: Learning from Failure with Philipp Schmieder

We talk with Philipp Schmieder about his experience creating a LiveView application for a political party’s convention and then watching the app blow up. We learn how he recovered, why it failed, and how he fixed it going forward. We also discuss some other application architecture ideas and how they might work. It’s a great post-mortem discussion where Philipp shares his wisdom so others learn from the mistakes. After experiencing all this, find out why he’s still bullish on LiveView and Elixir!
