AI Workflow Orchestration: How AI Agents Can Work Like Your Engineering Team

Imagine you are a beginner developer. You have been asked to build a new feature: “Add authentication to the application.” You open your AI coding agent, give it the instruction, and a few moments later it changes ten files. The code works. But then you start asking yourself: Why did it change these files? Why did it choose this architecture? Why is authentication implemented this way? Wh...

Breach monitoring from cron: no API key, no signup, just curl and jq

Most breach-monitoring setups die at step one: "create an account, generate an API key, add a payment method for when you exceed the free tier." Here is one that starts at step zero. I maintain XposedOrNot, a free, open-source breach index, and the check endpoint is deliberately keyless: curl "https://api.xposedornot.com/v1/check-email/you@example.com" You get JSON back. No signup, no to...

We Automated RCAs. The Real Value Was the Big Picture.

We Made Bug Tickets Write Their Own Root Cause Analysis. The Value Wasn't the RCAs — It Was What They Became in Aggregate. 🚀 Every bugfix now ships with a structured, machine-written root cause analysis, authored at fix time by a coding agent. It took under two days to build. Reading the last hundred of them back is what changed how we plan quality work. The Problem We wanted to answe...

Even With The Figma MCP, AI Eyeballs Your Design and Ships Pixel-Wrong UI

Every hardcoded value now traces to a Figma node, and "looks right" is no longer accepted as proof. We packaged the fix as a reusable Claude Code skill, implementing-figma-designs. It turned Figma-to-code from a "build it, then eyeball it against the PNG for three correction rounds" loop into a staged extract-then-prove protocol. The Problem An LLM handed a Figma frame will happily in...

My workstation was faking sleep: how a $15 meter caught 163 watts of waste

I have a Threadripper workstation with two RTX A6000s in my home lab — a machine I'm proud of and slightly afraid of, wattage-wise. A few weeks ago I noticed warm air coming from it while it was supposedly doing nothing, and went down a rabbit hole that ended with a number I didn't believe: my "suspended" machine was drawing 179.8 watts. Sleeping. One hundred and eighty watts. Here's the whole s...

Meet Velociradix: The 180,000 req/s C++17 Powered Web Framework for Node.js

Hey everyone! 👋 I've been working on Velociradix, an ultra-fast, zero-dependency C++17 HTTP engine and Node.js web framework. Why Velociradix? Standard Node.js frameworks execute HTTP parsing, header validation, and routing on the single-threaded V8 loop. Velociradix moves socket handling (kqueue/epoll), zero-copy HTTP parsing, and Radix Trie routing to native multi-threaded C++ backg...

How to query a custom element's internal elements while in the document from a DOMParser()?

How can the audio and script elements in the custom element be found within the DOMParser().parseFromString(...) result before adding it to the DOM? The MDN documentation for parseFromString reads: If the mimeType is text/html the input is parsed as HTML and elements are marked as non-executable, events are not fired, and event handlers aren't called to run inline scripts. Does "elements a...

Cascading Failures in Multi-Agent Systems

I still remember the day our support bot, powered by a LangGraph agent workflow, started behaving erratically. Customers would ask for help with their orders, and the bot would respond with irrelevant information or, worse, loop indefinitely. After digging into the logs, we discovered that the issue was caused by a cascading failure in our multi-agent system. One of the downstream services, respon...

Share Your Localhost With Anyone Using Cloudflare Tunnel

Vibe-coding memes aside, it is genuinely a thing We all might have faced. You're building something locally, someone asks to see it or you want to access it in your other devices, and then you realize there's no quick way to show them other than being on the same network and enabling port portforwarding and stuff. Deploying feels like overkill for a thing which may or may not be ...

European SaaS Expired Session Cleanup: Idempotent Python Drains Rate-Limited Workers

For a European SaaS, cheap expired sessions cleanup sounds like a cron calling a public URL; the real constraint is proving that retries cannot delete the wrong session or flood a constrained worker pool. Short answer: expose an authenticated public HTTP trigger, let cron call it, and make that trigger enqueue deterministic, retry-safe cleanup batches rather than deleting expired sessions inside ...

Gate the Patch, Not the Model: A Three-Check Loop for Untrusted Code Outputs

A generated patch can look correct and still fail in three ways that a prompt screenshot cannot show: it changes the contract, it imports a module the rest of the codebase does not allow, or it only works on the single example in the prompt. If you copy that patch into a real repository, you become the integration test, usually in a pull request late at night. This article walks through a short v...

A Flake Triage Card for Your CI: Classify Failures First, Read Logs Second

CI goes red for reasons that have nothing to do with your change. A port collision on a shared runner, a test that expects a clock to move, a missing dependency image, a stale cache, an assertion that finally caught a real regression. When every failure lands as a raw stack trace in a channel, the expensive part is not the failure; it is deciding which log to open. A small classification pass can ...

Traefik Host Collision: Why Duplicate Host Rules Break IngressRoutes

A service deploys perfectly clean. Pods Running, Endpoints populated, the Certificate resource says Ready: True, the IngressRoute shows no events. Then you curl the hostname and get back a 404 page rendered by your SSO provider, which you never attached to that route. Nothing in the deployment failed. Traefik logged nothing at error level. The 404 came from a service in a completely different nam...
