Why free chess analysis is always capped at one game a day

Most free chess game review gives you one game per day. Chess.com works that way, and so does almost every smaller site offering the feature. I assumed for a long time that this was just a paywall placed where it hurts. It is partly that. But there is a real cost sitting behind the cap, and once I worked out what the cost was, I built my own analysis site differently. The cost of one ga...

Building an AI Test Automation Factory: How We Reduced Automation Effort by 78% with Multi-Agent Systems & MCP

Traditional test automation frameworks often carry heavy maintenance costs, slow release cycles, and high knowledge dependency. By transitioning from standard script creation to a governed AI Test Automation Factory, engineering teams can shift their focus from writing boilerplate code to high-value validation and architectural optimization. Here is an architectural breakdown of how multi-agent A...

grow-hack: An AI Pipeline That Turns Any GitHub Repo Into Professional Docs in Under a Minute

Every developer has been there: you clone a promising repository, and the README is either missing, three years stale, or says "docs coming soon." Even when documentation exists, you still have to wade through thousands of lines of code to understand the architecture, entry points, and dependencies. grow-hack is an open-source project that aims to eliminate that pain. Paste a public GitHub URL, wa...

Similarity isn't relevance: the hard part of semantic search

Here's a dirty secret of search: "the closest match" and "the most useful result" are not the same thing. Return the mathematically nearest document and you'll often hand someone something technically related and practically useless. Relevance is a harder problem than similarity — and it's where good search is won or lost. Getting that right was the core challenge in the GovernAI Research Atlas, ...

Autonomous AI Study Notes: A Multi-Agent System with LangGraph and Streamlit

This post is my submission for DEV Education Track: Build Multi-Agent Systems with ADK. What I Built I built an Autonomous Multi-Agent Handwritten Notes Generator. Students and educators often need clean, visual study guides that resemble real handwritten notes, but manually summarizing technical subjects and formatting them takes hours. This system solves that by combining autonom...

OIDC: Keycloak setup for ALB Gateway API

Introduction In my previous article, I tested using ALB CRDs to offload JWT validation for OIDC-based authentication to the Amazon EKS Kubernetes API. In this article, I will share the Terraform/OpenTofu stack required to set up Keycloak as the OIDC provider and explain how it works. I am using the official Keycloak Terraform provider. The provider documentation clearly explains how t...

Put Your Docker Images on a Diet with Alpine Linux (2015)

Archival repost — originally published on my old blog on June 21, 2015, back when Alpine was still a dark-horse pick rather than the default. Already in English, lightly cleaned up for dev.to (fixed a few typos). Alpine did go on to become the mainstream slim-base choice — but it's not the automatic right answer anymore either: its musl libc trips up some native Node/Python modules, and DNS resolu...

From 45 to 70 Free Tools — Toollium Just Got a Lot Bigger

A few weeks ago I shared Toollium here — 45 free browser-based tools with no sign-up, no watermarks, and nothing uploaded to a server. The response pushed me to keep going. Toollium is now at 70 tools, and I want to walk through what's new and why I built it this way. The philosophy hasn't changed Same three rules as before: No sign-up, ever No watermarks on anything you export Files never le...

Technical SEO Checks I Run Before Writing More Content

“We need more content” is one of the most common conclusions in SEO. Sometimes it is right. Often it arrives too early. If search engines cannot reliably crawl, understand or index the pages already on a site, another twenty articles just create a larger pile of URLs with the same problem. Before planning content, I run a technical pass in a fixed order. It is not glamorous, but it stops expens...

I used JSON files instead of a database for 1,699 records. Here's what actually broke.

Three years ago I'd have called this a bad idea. I still might. But I've been running ryzenstudy.com on flat JSON files for months now — 1,699 exam paper records, 699 distinct subject codes, five academic programmes, zero database servers — and the failures haven't been the ones anyone warned me about. Nobody warned me about slugs. The setup It's a Next.js 15 app on App Router, one VPS, PM2 in ...
