Shadow work in engineering teams - an article on how to make your work visible for the organization and recognize the work that you do, but never account for.

Solid collection of practial stuff here. The Cloudflare postmortem is worth checking out if only to see how they document cascading failures.

The KISS vs DRY article feels timely too givenhow much abstraction bloat builds up over time in IaC configs.
