Kubernetes And Kernel Panics

The Netflix TechBlog

This blog post shows how to connect the dots from the worst case scenario (a kernel panic) through to Kubernetes (k8s) and eventually up to us operators so that we can track how and why our k8s nodes are going away. These orphaned pods represent real pain for our users, even if they are a small percentage of the total pods in the system.

Running A Page Speed Test: Monitoring vs. Measuring

Smashing Magazine

The other issue is that the data I’m getting back is based on lab simulations where I can add throttling, determine the device that’s used, and the network connection, among other simulated conditions. On that note, it’s worth calling out that there are multiple flavors of network throttling. Real usage data would be better, of course.

Is MongoDB Open Source? Is Planet Earth Flat?

Percona

We’re equally convinced on both counts, but in this blog article, we’re focusing on why MongoDB is not open source. This blog article traces key developments that coincided with MongoDB’s move away from open source software, and it examines how SSPL influence might have lured others in the same direction.
