Somewhat delayed because of Covid, I'm finally going to give my "inaugural lecture", which is a short, hopefully accessible, public talk: in my case "Some things I've learned about software"! All are welcome!

Go's execution tracer is a woefully underutilized tool. It contains tons of information about what is happening at any given moment that you won't get with a profile.
In addition to showing flight recording capabilities, this post provides a nice example of how to use tracing to diagnose a problem.
