Watch out for that tree! What mountain biking has taught me about proactive systems engineering.

Mountain biking is a lot like software engineering. No, really! There are skills to be learned, obstacles to overcome, patterns to recognize, leaders to follow, and new trails to explore!

In this talk I'll discuss a revelation I had one day as I was riding down the trail, about how I could apply that which I've learned over the years of trail riding to software and systems engineering. This will not be a talk about specific technologies or tools, but instead a reflection upon methodologies, monitoring/observeability, pitfall avoidance, and other engineering practices. Come have a laugh at the funny pictures, but also take with you perhaps some new insights or at least some new perspectives on healthy software and systems engineering, about how to be PROactive instead of REactive.
