Book chapter summary: Postmortem Culture, from the SRE Book
I’m really enjoying reading the excellent “SRE Book“. Chapter 15 in particular, “Postmortem Culture: Learning from Failure”, really struck a chord with me. The following is a slightly summarized version of it.
TLDR: Failures are inevitable, especially in distributed systems. To learn from them, document in Postmortems, avoiding blame, and share the newly gained learnings across your org.

Posting to LinkedIn
I find LinkedIn a useful platform for publishing content and reaching a wider audience than this blog does. I typically see better engagement on LinkedIn than I do from posting the same content on Twitter too.
But every time I go to post, I get confused between a post and an article.
Top 5 announcements from AWS re:Invent 2018
AWS re:Invent has just completed. It was a huge event with 50,000+ attendees across 7 of the biggest hotels in Vegas, and many new service announcements.
Serverless continue to get lots of attention with new lambda enhancements and better container support. The “hybrid” model of using your own datacenter in conjunction with a cloud provider has been fully embraced by AWS with the new “Outposts” capabilities. Machine learning also got much love with several new services using and supporting it. Read on for my top picks from this week’s announcements…

Talk summary: SRE principles by Tori Wieldt @ AWS re:Invent 2018
I caught a talk by Tori Wieldt at the New Relic booth at AWS re:Invent on “SRE principles”. Even though it was a short talk in the expo hall, rather than a formal scheduled one, it had a ton of good SRE material.

Intellij Maven folders
I haven’t been coding a lot recently, and when I spun up a new maven spring boot project and imported in to IntelliJ, I got confused about which folders are supposed to be marked as source (src, src/main or src/main/java?) and test (src/test or src/test/java?).

Notes from TechKnowCon 2018
I attended TechKnowCon (https://techknowcon.splashthat.com/) this week. I enjoyed the conference a lot. It centered around the theme of continuous learning, and how to instill a learning culture in your work environment. There were 2 talks in particular that I got a lot from, “Teach Like an Engineer” and “Peer learning at scale”…

Book summary: Distributed Systems Observability
“Distributed Systems Observability” is a book from Cindy Sridharan (find her on twitter, and medium), available as a free download here (registration required). At a little over 30 pages and 8,000 words, it is not a difficult read, and I definitely recommend it.
