Solid coverage of how email works. h/t Teo.

This leaddev post, however, does go into what to actually do about monitoring debt. h/t Kostas

This SO post on monitoring debt seems to miss over half of what monitoring debt actually is. Too many things being monitored. Bad noise levels in alerts. Knowing when the monitoring itself is failing. Updating monitoring systems both for just general bug fixes and for new functionality. Old monitoring that is no longer required. Etc.

A very long time ago, I designed a CS course that I felt would fill in the missing gaps of Massey’s CS degree. A lot of it was material like this “missing material”, except I only had the outline, not all the content. h/t Kostas

Nice post from fly.io about where issues have been and what’s being done about them. I wish more people were allowed to be this transparent. Maybe it’s just the people I interact with, but I feel everyone values this. h/t Kostas
