eBPF Beyond Security: Networking, Observability & Performance Engineering
A comprehensive guide to leveraging eBPF for high-performance networking, deep observability, and system performance optimization beyond traditional security use cases.
Edge AI Inference: Low-Latency Model Deployment at the Edge
Practical strategies for deploying AI/ML models at the edge with sub-millisecond latency, covering hardware selection, model optimization, and production deployment patterns.
Proxmox Clustering & High Availability for Self-Hosted Infrastructure
Step-by-step guide to building highly available Proxmox clusters with automated failover, live migration, shared storage, and production-grade self-hosted infrastructure.
Rate Limiting Patterns: API Protection & Traffic Management
Advanced rate limiting strategies for protecting APIs at scale, including token bucket, sliding window, distributed rate limiting, and graceful degradation patterns.
WebAssembly on the Server: Running Wasm Workloads Alongside Containers
Explore how WebAssembly is reshaping server-side computing with near-native performance, sandboxed execution, and seamless integration with existing container orchestration.
eBPF Is Not Just for Security. It Is Replacing iptables, Enabling Zero-Code Observability, and Profiling Production Without Overhead.
Most engineers hear "eBPF" and think security. Packet filtering. Maybe firewall rules. That is like hearing "electricity" and thinking "lightbulbs." eBPF is a programmable substrate inside the Linux
The Cloud Is Too Slow for AI. Edge Inference Is the Next Battleground.
Sending a camera frame to the cloud for AI inference takes 100-300ms round trip. For an autonomous vehicle, a medical device, or an industrial robot, that latency is not just slow — it is dangerous.
Your Single Proxmox Node Is One Kernel Panic Away From Total Downtime. Here Is How to Fix That.
A single Proxmox node is a single point of failure. One failed disk, one kernel panic, one bad update — and every VM and container goes down. For homelabs running anything that matters, that is unacce
Your API Rate Limiting Is Probably Wrong. Here Are the Patterns That Actually Work.
"Allow 100 requests per minute, then block." Sounds reasonable. Here is why it fails in production. A user sends 100 requests at 12:00:59 and 100 more at 12:01:01. They just sent 200 requests in 2 se
Your Containers Have 200ms Cold Starts. WebAssembly Does It in 1 Microsecond. Here Is Why That Matters.
A Node.js Lambda function takes 200-400ms to cold start. A WebAssembly module on Wasmtime takes 1-5 microseconds. That is not a typo. That is a 100,000x difference. WebAssembly on the server is not a
The $23/Month Infrastructure — Our Full Stack Breakdown
We run 84 containers, 47 public services, and a complete CI/CD pipeline. Monthly cost: $23. Everyone assumes you need AWS or GCP for production infrastructure. We proved them wrong with a single lapt
Docker Compose in Production — Why Most Teams Get It Wrong
Stop. Your docker-compose.yml is a ticking time bomb. I have reviewed hundreds of Docker Compose setups across startups and mid-size companies. The same 5 mistakes show up every single time — and the
Monitoring That Actually Works — Self-Hosted Prometheus + Grafana
Your monitoring is lying to you. Here is how I know. If your alerting strategy is "Grafana dashboard that someone checks manually" — you do not have monitoring. You have a screensaver. We built a mo
Docker Compose in Production: You Don't Always Need Kubernetes
We run 84+ Docker containers in production with zero Kubernetes. Here's why Docker Compose is still the right choice for 90% of teams — and what most "K8s-first" advice gets wrong. The industry push
Self-Hosted SSO with Authelia: Replace Auth0 for $0/month
We replaced Auth0 with a self-hosted SSO solution that costs us $0/month. No per-user pricing. No vendor lock-in. Full control over our authentication layer. Authelia sits in front of every service
CI/CD Pipeline with Gitea Actions: GitHub Actions Without GitHub
We migrated our entire CI/CD pipeline from GitHub Actions to self-hosted Gitea Actions. Same YAML syntax. Same runner architecture. Zero monthly cost. Here's why this matters: GitHub Actions minutes
Cloudflare Tunnel: Zero-Trust Access Without a VPN
We expose 47 services to the internet without opening a single port on our firewall. No VPN. No port forwarding. No public IP exposed. Just Cloudflare Tunnel. Traditional setup: open ports 80/443, c
Building a Private AI Chatbot with Ollama and Open WebUI
We run our own ChatGPT-like AI assistant on a $500 server. No API costs. No data leaving our network. Full control over the models we use. Here's the reality most people miss: you don't need an H100
