Hilarious Q2 major outage report
Colin Bartlet from "StatusGator" published this wonderful report of some high-profile 2020 Q2 service outages. I chased the link of slack's root cause analysis that was also informative. I know of at least one other company where the culture is very similar to that of T-Mobile, and issues are hidden.

Aftershocks: Palladium Wars Book 1 by Marko Kloos
Not much going on as the book sets the stage for the rest of the story to come in future books. Interesting universe. Abrupt ending in the middle of the story, though. 3/5 Stars.

Software Engineering presentations for a non-technical audience
Hilary Nussbaum has some thin but interesting advice for development managers who are trying to communicate what they have done to a non-technical audience. She concentrates on three measures of code velocity to illustrate a team's success at planning and execution. But she also recommends discussing customer-affecting reactive support incident volume to reflect quality. She frames her advice as a CTO talking to her board of directors but the ideas are applicable to a development manager at any level of any organization.

What's the difference between monitoring and observability?
Charity Majors has some (strong) opinions about the differences. Fundamentally, monitoring is to keep track of known unknowns (1OI or first order of ignorance). Observability is to speed detection, diagnosis, and recovery from unknown unknowns (2OI or second order of ignorance). She articulates in great detail what all she considers requisite for true observability and creates an awesome wishlist. I stumbled upon her definition because I was reading Charity's recent article expressing her views on the evolution of the operations role in an organization.
