Building a Local Chatbot with Typescript, Express, Langchain, and Ollama (Qwen)

In the world of AI-powered applications, large language models (LLMs) like OpenAI’s GPT models get most of the attention. However, running your own model locally offers several advantages: no API costs, no rate limits, and complete control over your data. In this article, we'll walk through building

Ship It (Go Edition)

Containerize your app and publish to GHCR with GitHub Actions This guide adds a Dockerfile that bakes in the Git SHA, and a GitHub Actions workflow that builds and pushes to GitHub Container Registry (GHCR). Tags drive versions. The image carries the commit SHA in both runtime output and OCI

Balancing Code Quality and Developer Velocity with GolangCI-Lint

When you bring linting into a Go project, the temptation is to flip every switch on. The result? A flood of red in your first pull request, frustrated developers, and a quick trip to golangci.yml to start turning things off. A better approach is to start with a balanced

Add Opinionated Formatting and Linting to a Go Project

You ship faster when your codebase looks the same everywhere. Formatting and linting remove style debates, catch bugs early, and keep reviews focused on behavior—not whitespace. In this guide, you’ll add two things to any Go repo: Formatting with gofumpt (a stricter gofmt). * Linting with golangci-lint (one fast

golang

Getting Started with Go

Golang, or simply “Go,” is often praised for its simplicity, speed, and first-class support for concurrency. It compiles fast, runs fast, and ships as a single binary. Whether you're building cloud-native tools, high-performance APIs, or simple command-line utilities, Go has you covered. In this article, we'll

Adding DevContainers to a Python Project

If you're already using a Dockerfile to containerize your Python project, you're 90% of the way toward a seamless development experience using DevContainers, a feature of Visual Studio Code, which lets you define a repeatable, consistent development environment using Docker. This means zero "works on

How to Add a Dockerfile to Your uv Project

A good Dockerfile is like a clean kitchen; you can step in, cook your app, and know exactly what’s going into the final product. For Python projects that use uv, adding a Dockerfile is straightforward, but a few best practices will make your image smaller, faster to build, and

python

Getting Started with FastAPI Using uv

FastAPI is one of the fastest-growing Python web frameworks, thanks to its speed, modern syntax, and ease of use. But when you combine FastAPI with uv for dependency management and Docker Compose watch for live reloading, you get a development workflow that’s both fast and frictionless. In this guide,

NextJS

Kickstarting Your Next.js Project the Right Way

From zero to a scalable frontend with modern tooling Next.js has quickly become the go-to React framework for building modern, performant web apps. Whether you're creating a dashboard, a marketing site, or a full-stack application, Next.js offers sensible defaults, batteries-included tooling, and production-ready features out of

Kubernetes

Getting Started with ArgoCD Using Helm and Ingress

You’ve got a Kubernetes cluster up and humming. Now it’s time to deploy applications the GitOps way—with ArgoCD. In this guide, we’ll use Helm to install ArgoCD, configure an Ingress with cert-manager for automatic TLS, and wire up your Git repository (argocd-example) to manage application deployment.

CICD

GitHub Actions Development with act

GitHub Actions have become the go-to automation tool for CI/CD workflows. But there’s a catch: debugging them can feel like shooting in the dark. You commit, push, wait, and hope it works. That’s where act shines. act brings GitHub Actions to your local machine. It lets you

Securing Internal Kubernetes Apps with Google Login Using OAuth2 Proxy

Internal tools are handy, but they can be dangerous when exposed. Here’s how to guard them with Google login and Kubernetes. Why Secure Internal Apps? Maybe it’s your admin dashboard. Maybe it’s a tool only your dev team uses. Either way, internal apps often start wide open,

Automate Kubernetes DNS with ExternalDNS and Cloudflare

Manually managing DNS records every time you spin up a new Kubernetes Ingress resource is a tedious task, especially in fast-paced environments. That’s where ExternalDNS comes in. This tool automates the creation and management of DNS records in providers like Cloudflare, using Kubernetes-native resources like Ingress. In this guide,

How to Install and Configure cert-manager with Cloudflare on Kubernetes

When deploying modern apps to Kubernetes, HTTPS isn’t optional. Manually managing TLS certificates is tedious and prone to errors. This is where cert-manager comes in. It's a Kubernetes-native certificate management controller that automates the lifecycle of SSL certificates. In this tutorial, we’ll walk through how to

Spinning Up a Civo Kubernetes Cluster

Kubernetes is powerful, but setting it up doesn't have to be a painful process. If you're looking for a fast, simple way to get a cluster running, Civo is a fantastic option. With lightning-fast provisioning and a developer-friendly interface, it's ideal for test environments

Windows

Dependency Walker – A Vintage Tool That Still Delivers in DevOps

Why Dependency Walker Still Matters in 2025 If you've ever shipped a Windows app only to hear “it works on my machine” when it crashes elsewhere, you’re not alone. One of the most common culprits? Missing or incompatible DLLs. In DevOps, where speed and automation rule, subtle

typescript

Typescript Linting

Think of linting as your code’s first line of defense, like a spell checker for your syntax and structure. It analyzes source files to identify errors, enforce style guidelines, and highlight patterns that may lead to bugs. By integrating linting into your development workflow or CI pipeline, you create

python

Python Linting

Linting is like a spell check for your code. It scans your files for common errors, formatting issues, and bad practices before they ever reach production. By enforcing consistent style and catching bugs early, linting tools help teams write cleaner, more maintainable code. When integrated into a build pipeline, linting

python

Python Project Setup with uv

There are many different ways to get started with a Python project. You can create a new directory and use the python executable in your path, or you can use virtualenv to isolate your development environment from your default python environment. Then there are environment management tools, such as poetry,

Easy to use Dev Environment

Why You Should Use Static Analysis Tools Like ESLint or Ruff

Modern development moves fast. Code gets pushed, pulled, reviewed, tested, and shipped within hours, sometimes minutes. In that kind of high-velocity environment, static analysis tools like ESLint (JavaScript/TypeScript) and Ruff (Python) help you catch problems before they become problems. They act like a second pair of eyes, always watching,
