Yesterday I shipped 1.9.0. Got a solid mix of hate and genuinely useful feedback. Didn't sleep. Took all of it personally. Built 2.0.0 instead. No po
I have been working on a realtime multiplayer server in Go. The transport layer is WebSocket using gorilla/websocket, and most outbound payloads are
This is the story of why I rebuilt google-researcher-mcp (Node.js/TypeScript) from scratch as web-researcher-mcp (Go), and what the lessons learned al
4 hours of sleep a night for the past few days. ForgeZero went from 1.0 to 1.9.0 in that time. This isn't work anymore. This is obsession. Let me
So I've been solo-building fz — a fast, opinionated build tool for C/ASM projects written in Go. No Makefile hell, no CMake nightmares. Just a single

How embedding schema versions in every data file — observations, controls, output, baselines — enables forward compatibility, fail-fast loading, and c
In the previous article we defined the Canary CRD. Now we build the Operator: the controller that watches Canary resources and drives the actual relea
In the previous seven articles we've thoroughly explored the Informer framework — Reflector, DeltaFIFO, Indexer, WorkQueue, EventBroadcaster, and the
Over the past six articles we've examined each component of the Informer framework individually. Now it's time to look at the component that wires the
In the previous article we covered WorkQueue — the retry and rate-limiting backbone of controllers. In this article we look at a different but equally
In the previous article we saw how Indexer stores and indexes resource objects for fast local queries. Now we look at the other half of the controller
In the previous article we saw that HandleDeltas routes every event to two destinations — one of them is Indexer. Indexer is the local in-memory cache
In the previous article we saw how Reflector calls List/Watch and feeds events downstream. The immediate destination of those events is DeltaFIFO — th
In the previous article we saw that Informer's core mechanism is List/Watch. The component responsible for executing that mechanism is Reflector. Ever
