CatOps Digest 2023-12-26
What was on CatOps in the last two weeks and more...
Welcome to the last CatOps digest of the year 2023!
Thank you for being with us all this time! First of all, this newsletter made it through the whole year! To be honest, I was not sure that I would keep writing these digests this long.
We made our voice chats somewhat regular. We already have 15 recordings available on YouTube, Spotify, Apple Podcasts, and Google Podcasts. Plus, there’s a new episode currently in the making!
We also had a recurrent “Monday Donations” topic to remind you about the important ongoing fundraisers. Just recently a huge 330M UAH fundraiser “Protect the Sky” has reached its goal! You have taken part in it as well!
Plus, you can also read CatOps on WhatsApp now. However, it’s still experimental, I would say, because WhatsApp’s UX isn’t very welcoming.
With this been said, let’s wrap up this year with the last CatOps Digest of 2023!
Charity
There are still big fundraisers going on. Apart from various initiatives to get more FPV drones, there are two big fundraisers by the “Come Back Alive” foundation:
For de-mining the territory together with Kyivstar
Time Sensitive
A Linux Book Bundle - you still have about two weeks to grab 20+ books about Linux.
Software Development Book Bundle - it’s about a week left to grab this bundle that also contains some books about CI/CD and SRE.
Digest
How Uber Computes ETA at Half a Million Requests per Second - how Uber shows you ETA based on some graph theory, map slicing and predictions.
We built network isolation for 1,500 services to make Monzo more secure - a story of Kubernetes network policies implementation by Monzo with some interesting view on the UX.
K8s-cleaner - a tool to cleanup stale resources in Kubernetes.
Database Fundamentals - a summary of two excellent books - “Database Internals” by Alex Petrov (he’s from Kharkiv, BTW) and “Designing Data-Intensive Applications” by Martin Kleppmann.
Simple sabotage for software - yet another article on what not to do in software engineering.
That’s all, folks! I wish you pleasant holidays and see you next year!
