walk

Walk — a terminal navigator.

Why another terminal navigator? I wanted something simple and minimalistic. Something to help me with faster navigation in the filesystem; a cd and ls replacement. So I build walk. It allows for quick navigation with fuzzy searching, cd integration is quite simple. And you can open vim right from the walk. That's it.

A deep dive into CPU requests and limits in Kubernetes

In this post, we are going to dive a bit deeper into CPU and share some general recommendations for specifying CPU requests and limits. We will also explore the differences between using the default policy (CFS quota) and the CPU Manager’s static policy. We are not going to consider memory resources in this post.
