Containers, orchestration, monitoring, and the workflow between writing code and running it.
A pull request checkout, a poisoned GitHub Actions cache, and an OIDC token pulled straight out of runner memory. That's how 84 malicious versions of TanStack's packages hit npm in six minutes.
Build a production-grade monitoring stack with Prometheus and Grafana from scratch. Covers architecture, Docker Compose deployment, Node Exporter, alerting with Alertmanager, PromQL from basics to advanced, pre-built dashboards, and everything CoderOasis uses to monitor its own infrastructure.
CoderOasis runs Teleport internally for everything — admin panel access, secure database connections, Kubernetes, and zero-trust philosophy across our entire team. This is the complete technical guide to installing, configuring, and running your own self-hosted Teleport cluster from scratch.
Your application is only as secure as every package it depends on. In September 2025, attackers compromised 27 npm packages with 2.6 billion weekly downloads by phishing one maintainer.
Infrastructure as a Service gives you virtualized servers, storage, and networking on demand without owning any hardware. You rent compute and own everything that runs on it. Here is what IaaS actually is, what it demands from you.
Platform as a Service sits between raw servers and fully managed software. You push code, the platform runs it. No Nginx config, no OS patches, no 3 AM server alerts. Here is what PaaS actually gives you, what it costs you in control, and how to decide if it is the right layer for your application.
Git tracks every change to every file in your codebase, lets multiple developers work simultaneously without overwriting each other, and gives you a complete history you can rewind to any point. It is the foundation of modern software development. Here is how it actually works.
Kubernetes runs your Docker containers across a cluster of machines, handles scheduling, health checking, rolling deployments, auto-scaling, and self-healing. When your application outgrows a single server, Kubernetes is how it runs on ten.
Docker packages your application and everything it needs to run into a container that behaves identically on your laptop, your teammate's machine, and the production server. "It works on my machine" stops being a problem. Here is how it actually works and what production usage looks like.
Past the benchmark charts and feature matrices — here's what Deno's permission system and Bun's native APIs look like when you build something real with them. The gotchas, the sharp edges, and the parts that are actually better than Node.
You tuned G1 flags for a week. Your pod has one CPU, which means the JVM quietly picked a single-threaded collector at startup and ignored every flag you set. Here is the OpenJDK source that made that decision.
