CatOps Digest 2025-06-17
What was on CatOps in the last couple of weeks...
I’m experimenting a bit with the day of the digest. Substack allows only 5 variants per poll, so given that Monday is dedicated to donations, what days are the best for you to get this digest?
Charity
There is a big ongoing fundraiser by DOU.ua for reconnaissance drones for the 3rd Assault Brigade. They have a dedicated website for it with more information (available in Ukrainian). Also, here’s a Monobank jar for direct donations:
Time Sensitive
“Machine Learning AI and Bots” O’Reilly - 6 days left.
“Cybersecurity and Forensics” by Pearson - also 6 days left.
“Coding for Curious” by No Starch - 13 days left
Surveys
2025 Stack Overflow Developer Survey - an important global analysis of the industry! Make sure to add your voice there!
DOU Salary Survey (in Ukrainian) - an important survey for the Ukrainian Tech industry. They also include voices of the Ukrainians abroad.
Digest
How Big Technical Changes Happen at Slack - a truly timeless article by Slack on how they adapt new technologies. If you read a single article from this whole list, let it be this one!
AI: What is the MCP? - a general overview of what is an MCP (model-context-protocol) with some code examples by Arseniy Zinchenko.
AI: writing an MCP server for VictoriaLogs - the continuation of the previous article with a more concrete example. BTW, make sure to subscribe to Arseniy’s Subtack!
Wardley Maps & Pace Layering for Senior Tech Leads and Engineering Leaders - another great blog from Alex Ewerlöf. He usually writes about higher-level topics, though.
How we migrated onto K8s in less than 12 months - a story of how Figma migrated to Kubernetes with realistic timeframes.
That’s all for now, folks! See y’all in about two weeks!
