Programming Digest
As you build a computer system, little things start to show up: maybe that database query is awkward for the feature you are building, or you find your server getting bogged down transferring gigabytes of data in hexadecimal ASCII, or your app translates itself to Japanese on the fly for hundreds of thousands of separate users.

This article by Teleport focuses on recipes and best practices concerning API access control hardening in the Kubernetes cluster.
Twenty five thousand dollars of funny money
I used to work at a place that sold ads. One of the things this company wanted was for the employees to try it out and see what it was like to actually use the ads product themselves. It's the usual "dogfooding" thing you hear about sometimes.
We'll wrap up with a bit of a cloud theme today. ☁️
