This is an older article, but hopefully still useful nevertheless: Brian Mathews explains how to use the linkerd sidecar to find and fix application issues on Kubernetes. Here’s a two-part series (so far) on setting up a multi-architecture Kubernetes cluster ( part 1 , part 2 ). Operating Systems/Applications.

It seems like the natural progression of the Tech Short Takes is moving toward monthly articles, since it’s been about a month since my last one. Redpill Linpro talks to readers about their new routers running Cumulus Linux. This article from Bruce Schneier is worth reading. Both are good articles. Servers/Hardware.
