Change tracking and soft delete: audit trails without the boilerplate

Idempotency in CQRS and Event Sourcing — Part 2: commands, projections and outbox

In HTTP, idempotency is straightforward: store the key, return the cache. In a CQRS/Event Sourcing system, it's more subtle. The command may be idempotent, but what about the event it generates? The projection consuming it? Idempotency must cross the entire stack. If you haven't read part 1, it covers the basics and the HTTP implementation in Go — with a complete PostgreSQL store that replaces Re...

Built tasuki — an AI CLI Orchestrator that Seamlessly Hands Off Between Tools

I built and open-sourced tasuki, an AI CLI orchestrator that automatically rotates between Claude Code / Codex CLI / GitHub Copilot CLI based on priority. Repository: https://github.com/0xkohe/tasuki Motivation I’m the kind of person who prefers subscribing to multiple AI tools at $20–$30 each rather than committing to a single $100–$200 plan.

How I Got OpenStack Keystone Running on Windows: A Collection of Hacks

Introduction Some projects are born from a simple question: "Will it work?" This is one of them. OpenStack Keystone — the OpenStack cloud identity and authentication service — was designed, developed, and tested exclusively on Linux. The official documentation doesn't even mention Windows to advise against it. It simply doesn't exist in that context. And yet, here we are. What initia...

Sub-queries vs Window Functions vs Common Table Expressions: Which Should You Use in SQL?

SQL is the most used tool for data manipulation but what happens when there are some concepts that seem to work towards the same ultimate outputs. As queries become more complex, developers often encounter different techniques that appear to produce similar results—namely sub-queries, common table expressions (CTEs), and window functions. At first glance, these concepts can seem interchangeable. ...

React Concepts That Finally Click (Vite, JSX, Components & Folder Structure, npm vs npx and Dev Server)

You know that moment… You open a React project, stare at the files, run a command, and everything works — but deep inside you're thinking: “I don’t fully get what just happened.” Not because you’re not capable. But because most explanations skip the why and rush into the how. So here’s a different approach. Instead of throwing definitions at you, we’re going to decode what’s actually happen...

The Job That Stayed. The Work That Left. AI is not removing positions from Indian workplaces. It is removing what those positions used to build inside the people holding them. Peter approves thirty-six rows before noon. The software read twelve hundred invoices. The software matched the vendors. The software entered the numbers.

Does JavaScript provide a built-in way to detect stale async results?

I’m working with async JS and ran into a common pattern where multiple async calls can overlap and return out of order. e.g let currentQuery = ""; async function search(query) { currentQuery = query; const result = await fetch(`/api?q=${query}`); const data = await result.json(); if (query !== currentQuery) { // ignore stale result return; } display(data); } This...

AI created slow and expensive code. How I analyzed and fixed it.

My AI-built browser game portal was growing. That was good news - until Firebase bills started rising and performance got worse. Now was the moment where I as a software engineer had to step in. With an increasing user base playing more and more games every day, I slipped out of the free usage tier for Firebase Storage which I use for persistency.

The moment ClickHouse writes CPU code for your query You run SELECT category, COUNT(*) FROM events GROUP BY category against 100 million rows.
