When building services that need to run reliably, you face three fundamental problems: managing secrets securely, deploying workloads consistently, and enabling services to find each other. HashiCorp’s stack addresses these with Vault, Nomad, and Consul. This guide shows how to set up and integrate all three based on what I learned while building infrastructure for distributed services. ...
As software engineers, we often work with systems that abstract away the fundamental concepts of operating systems. We deploy containers to Kubernetes, scale web services, and optimize database queries without thinking deeply about the underlying resource management. Yet understanding these foundations becomes crucial when we hit performance walls or design systems that need to handle thousands of concurrent operations efficiently. This guide covers CPU scheduling algorithms for systems engineers, backend developers, and DevOps professionals. These concepts help when optimizing microservice architectures, debugging performance issues, or working with distributed systems. ...
Model Context Protocol (MCP) enables AI assistants to interact with external tools and services. In this guide, we’ll build a simple calculator server that demonstrates MCP concepts by creating a tool that Claude (or other MCP clients) can use to perform mathematical calculations. ...
This guide walks through deploying a Go web server on Kubernetes, covering Docker containerization, setting up a local Kubernetes cluster with Minikube, and deploying the application. ...
