This is an engrossing write-up of the Chernobyl incident from the perspective of complex systems and failure analysis.

Slack’s Disasterpiece Theater isn’t quite chaos engineering, but it’s arguably better in some ways. They carefully craft scenarios to test their system’s resiliency, verifying (or disproving!) their hypothesis that a given disruption will be handled by the system without an incident. They share three riveting stories of lessons learned from past exercises.

The process each Disasterpiece Theater exercise follows is designed to maximize learning while minimizing risk of a production incident.

In this post, we’ll share the algorithms and infrastructure that we developed to build a real-time, scalable anomaly detection system for Pinterest’s key operational timeseries metrics. Read on to hear about our learnings, lessons, and plans for the future.

I sure do love a good debugging story.

When an incident occurs, your company is faced with a choice: do you seek to learn as much as possible about how it happened, or do you seek to find out who messed up?
