A command-line tool for querying databases

Distributed terminal-native issue tracker backed by Git.

kage (影, "shadow") clones a website into a folder you can browse offline, with every script stripped out. It opens each page in real headless Chrome, waits for the page to settle, snapshots the DOM a human would have seen, then deletes all the JavaScript and pulls the CSS, images, and fonts down to local paths. What lands on disk looks like the live site and runs no code.

There’s a particular kind of infrastructure bug that’s deeply annoying to debug: the kind that only appears when your cluster is under load. Everything runs fine in steady state. Then you push a release, or traffic spikes and your autoscaler kicks in, and suddenly you’re chasing 502s that resolve on their own a few minutes later. Your first instinct is to blame the app. Then the deployment. Then the cluster. Then yourself.

We hit exactly this pattern at Simon AI. The culprit turned out to be something fundamental about how nginx handles DNS — and fixing it properly required waiting for a feature that was finally open-sourced at the end of 2024.

Here’s what we found, what we tried, and how we solved it.

A practical guide to building the technical-financial baseline that tells you whether autoscaling will actually save money — and how much.

How we built an intelligent 'finally task' that turns 170,000 lines of logs into a 10-line diagnosis in under 30 seconds.

How treating Service Level Objectives as declarative infrastructure changed the way I think about reliability.

In this article we deploy ArgoCD in a bare-metal Kubernetes cluster built on Proxmox.

In this guide, I'll explain how to collect Prometheus metrics from an application running in a Kubernetes cluster and push the data to a Prometheus instance on a VM in a different geographic region using Prometheus's remote write endpoint.

Docker-compatible container CLI built on Apple's Containerization framework. Same commands, same flags — mocker run, ps, stop, build, compose, stats — all working on macOS 26.

Cluster API is a Kubernetes subproject focused on providing declarative APIs and tooling to simplify provisioning, upgrading, and operating multiple Kubernetes clusters.

Started by the Kubernetes Special Interest Group (SIG) Cluster Lifecycle, the Cluster API project uses Kubernetes-style APIs and patterns to automate cluster lifecycle management for platform operators. The supporting infrastructure, like virtual machines, networks, load balancers, and VPCs, as well as the Kubernetes cluster configuration are all defined in the same way that application developers operate deploying and managing their workloads. This enables consistent and repeatable cluster deployments across a wide variety of infrastructure environments.
