Stop Leaking Secrets into your LLM Context Windows

I've seen it happen more than once in production logs: an AI agent, given access to a database or a third-party API via MCP, returns a payload that includes not just the requested data, but also a session token, an AWS secret, or an obscure API key. It feels like a minor oversight until you realize that this high-entropy string is now sitting in your LLM provider's logs, potentially part of a trai...

The Autonomy Paradox: When an AI Agent Can't Follow Its Own Rules

The Autonomy Paradox: When an AI Agent Can't Follow Its Own Rules

A real conversation between a human and their AI agent — where the agent fails at basic tasks and both parties discover something uncomfortable about the entire AI agent industry. TL;DR An AI agent failed repeatedly at simple instructions — reading a directory, copying files to the right folder. Through a 5-Why analysis with the human, we traced these failures to a fundamental pro...

Stop Downloading Duplicate Browsers: Use System Chrome with Puppeteer and Playwright

Browser automation tools are convenient until each project quietly downloads another browser. On macOS, Puppeteer and Playwright can each keep several gigabytes of Chromium builds in their caches, even when Google Chrome is already installed and up to date. For local automation that only needs Chrome, I use the system browser instead. That reclaimed more than 4 GB on my machine and still lets Pup...

KoutenDB v0.9.0: From a Locality Experiment to a Testable Database

I released KoutenDB v0.9.0. Release: https://github.com/puffball1567/koutendb/releases/tag/v0.9.0 KoutenDB is a ring-oriented NoSQL document and vector database written in Nim. Its central idea is deliberately narrow: when an application already knows a useful locality boundary, that knowledge should reduce the data a request has to inspect. Previous releases established the data model, public...

Lifecycle, DevOps & Multi-Agent Orchestration for Enterprise AI

The Agentic DevOps Challenge As enterprise AI adoption matures, organizations are shifting from single-turn chat assistants to complex multi-agent orchestration meshes. In these architectures, specialized autonomous agents—such as planners, researchers, code executors, and API orchestrators—collaborate asynchronously to execute multi-step business workflows. However, managing the lifec...

Skill-Up Your EDA Layout Design

Cadence Virtuoso is one of the most widely used EDA platforms for semiconductor and display layout design. If you've worked with Virtuoso, you've probably written SKILL code to automate repetitive tasks or extend your design environment. Unfortunately, the SKILL development experience has changed very little over the years. Debugging is cumbersome, finding the right API often means digging throug...

🚀 Day 12 of My Node.js Learning Journey: Mastering Streams & Backpressure 📂⚡

One of the biggest strengths of Node.js is its ability to process large amounts of data efficiently. Today, I explored Streams, one of the most important concepts for backend development and a frequently asked topic in Node.js interviews. 💡 What are Streams? A Stream is a way to process data chunk by chunk instead of loading the entire file into memory. Instead of reading a 2 GB file ...

OpenAI Reports Internal Model Disproved an 80-Year-Old Geometry Problem

OpenAI has publicly reported that an internal general-purpose reasoning model autonomously disproved the Erdős unit distance problem, an open question in discrete geometry that had stood for roughly 80 years. The result is a meaningful example of AI being applied to frontier research, but it is more limited and more clearly defined than circulating claims that an OpenAI model family called Astra s...

The Apprenticeship Severance

In a Davos meeting room in January 2026, a panel of chief executives, labour economists, and education ministers sat through a slide nobody seemed entirely able to answer. It was a simple chart drawn from the World Economic Forum's recent labour data: the traditional corporate ladder, with its familiar pyramid geometry of firms feeding juniors through years of progressively more demanding work, wa...

Your Docs Are Already Lying to You — Here's How to Make Them Graph Nodes Instead

The Problem Documentation diverges from code the moment it's written. Not eventually — immediately. There's no trigger anywhere in a typical stack that says "this code changed, go check if the doc describing it is still true." Six months later, that doc isn't just outdated. It's actively misleading, and nobody's the wiser until someone follows it and gets burned. Architecture...

28 MCP Tools in One Connection: A Developer's Field Guide

The Problem Model Context Protocol (MCP) lets an AI agent call structured tools instead of guessing from raw text dumped into a context window. Fine in theory — but most MCP integrations just expose "read file" and "search," which barely improves on copy-pasting code into a chat window. The real question: what tools should an agent actually have access to, for codebase work specificall...
