A practical guide to Git control files like .gitignore and .gitmessage and how they affect behavior.

Terraform has been my bread and butter for the past few years as the tool for Infrastructure as Code. I’ve dealt with a variety of patterns while working with Terraform, and noticed one pattern that is rarely discussed, but super useful. Feature flags are a way to write code that can behave differently based on how we configure things, and is as old as writing code for computers. It gives the author of the code flexibility to have different implementations, safely migrate systems from one approach or capability to a new one and choose behaviour based on the target context. Mature codebases find tooling or affordances that give them the ability to evolve and adapt, and feature flags are one pattern to achieve that. However, the public internet has very few examples about how to achieve this for Infrastructure as Code tools, including Terraform.

This case study explains how JVM tuning, a smaller Hikari pool, and faster HPA scale-up doubled traffic capacity while reducing baseline pods.

This article distills incident-driven lessons on troubleshooting, configuration mistakes, and operational habits that make Kubernetes outages worse.

This article covers rebuilding a Kubernetes platform for GPU workloads to reach 99.9% uptime after operational instability.

At VictoriaMetrics, we built vlagent as a high-performance log collector for VictoriaLogs. To validate its performance and correctness under a real production-like load, we developed a benchmark suite and ran it against 8 popular log collectors. This post covers the methodology, throughput results, resource usage, and delivery correctness.

This tutorial walks through building a Go game server with Agones, matchmaking, Fleet allocation, and autoscaling on Kubernetes.
