This is definitely one of the reasons I wrote this article. To be able to see the cause/effect when a problem is very convoluted is something difficult to learn and difficult to teach.

A story I have heard several times in different instances is some light sensitivity, I think this happened to the Raspberry Pi team (PMIC transient induced by camera flash).
