Turning a job search spreadsheet into a local-first vault
Why I threw away the RAG pipeline and kept the retrieval
Since 2012 I've been able to look up every job application I've sent — at first because the job board remembered for me, later because I kept a LibreOffice spreadsheet with colour-coded rows.

Here is how it became a vault of plain markdown files with an MCP server on top, and what I built and threw away on the way.

Spinning out a High Available Kubernetes cluster with kubeadm
Deploying a production-ready Kubernetes cluster locally in virtual machines with kubeadm
In most cases, a local cluster of one server is sufficient for application development. And in some implementations it is not a virtual machine but a container. There are a lot of tools k3d and minikube just few of them.
But if you need to prepare for deploying a production cluster on your own, or to test the fault tolerance of distributed storage from an open source project, or to prepare for the CNCF exam. In such cases I have found it useful to have a cluster on my laptop as similar as possible to the one in production.
Here is step by step instructions on how to deploy kubernetes cluster with multiple control-plane nodes(ie high available cluster) on virtual machines using kubeadm.
