When Did AI Become the New Toy? I Just Got Here.

When building autonomous AI agent systems and high-dimensional generative pipelines, one critical question emerges: How do we guarantee that generated candidate proposals never execute unverified or unauthorized actions against operational technology (OT) or live systems? To solve this, we designed the **AGY Witnessed Admission Fabric v0.1** — a fail-closed, OPA-governed Read-Only OT s...

What actually belongs in CLAUDE.md — and what to move to skills, hooks, or docs

Your CLAUDE.md only grows. Every incident adds a rule, every preference becomes a paragraph, and six months in you have a file that reads like a wiki — and an agent that follows maybe half of it. The uncomfortable mechanics: CLAUDE.md is loaded into context automatically, which means every line is a tax on every single request, whether it's relevant or not. And instructions are advisory — the mor...

Everything Wrong With Zenovay, In Order

Zenovay is a complete fraud. Here's every piece of it. The founding story doesn't add up. The About page claims the platform launched in 2023. The domain zenovay.com wasn't registered until 2025-07-28. The team doesn't exist. All blog author profile pictures are AI-generated, flagged by SynthID, and the posts themselves are AI-generated. This includes "Engineering Lead Martin Hale." There is no...

GPTBot is hammering your API. Block it, or charge it?

Check your logs for last month. Filter user-agents for GPTBot, ClaudeBot, PerplexityBot, Google-Extended, bingbot. For most SaaS apps and content APIs in 2026 that's now a real percentage of total requests — traffic you pay to serve, from callers who never convert, never see an ad, never subscribe. The reflex is robots.txt or a blocklist. Three problems: Blocking is leaky. Polite bots honor rob...

The one seam, shown: Inline up close

In post 10 I closed the composition-versus-coherence question with one paragraph: I kept strict object-scoping, reserved an Inline operator for later, and rejected automatic reach-down. That was true, and it was too fast. A reader told me the reserved operator was not clear from a sentence, which is fair. A design record that asserts a decision without showing it is not really a record. So here is...

The Great Ubuntu Blackout: My 3-Hour Journey to Fix the Darkness

Introduction It was a perfectly normal day. I opened my laptop, ready to get some work done, and then... BAM. A black screen. Not a gentle fade to black, but more like my computer shouting, "I’ve had enough of your crap!" The same operating system that had been working perfectly just five hours earlier had suddenly decided it had had enough of life. I wasn't too worried though. Afte...

Lesson 3 - Architecture: Learn to organize your thoughts

AI takes the path of least resistance. That one characteristic explains most of what changed for me about architecting a system once an agent was in the loop. It is genuinely faster than I am on frameworks, patterns, and the standard way to wire something up. Since it has read more on them than I have. But "least resistance" means it optimizes for the thing in front of it, e.g., getting an endpoi...

Building an On-Premise Kubernetes Cluster — Part 6: Deploying, Updating, and Scaling Your Own Application

In Part 5 of this series, we validated the cluster end to end by deploying Nginx. Now let's go one step further: build a custom application's Docker image, publish it, get it running in the cluster, and explore day-to-day operations — version updates, rollback, and scalability (both manual and automatic). As an example, we used a simple REST API (myapp.war), built with Spring Boot, purely for ill...

Building an On-Premise Kubernetes Cluster — Part 5: Deploying Your First Container

In previous parts of this series, we built the cluster from scratch: prepared the environment (Part 1), installed containerd and Kubernetes (Part 2), initialized the control-plane (Part 3), and joined the workers (Part 4). With the cluster up and all nodes in Ready state, it's time to actually put it to work: let's deploy our first application. In this article, we'll use Nginx as an example — a c...

Building an On-Premise Kubernetes Cluster — Part 2: Installing Containerd and Kubernetes

In Part 1 of this series, we prepared the environment: defined the hardware, configured /etc/hosts, adjusted the firewall, and disabled SWAP on all nodes. Now that the foundation is ready, it's time to install the container runtime (containerd) and the Kubernetes packages themselves (kubelet and kubeadm). All the steps below should be run on all servers in the cluster — master and workers — unles...

Building an On-Premise Kubernetes Cluster — Part 1: Preparing the Environment

This is the first part of a series where I'll share, step by step, how I built my own on-premise Kubernetes cluster, without relying on any cloud provider. The goal is to document the whole process — from environment preparation to a working cluster — as a reference for anyone studying the topic or looking to replicate the same setup at home or at work. I used VPS (Virtual Private Server) and VM ...

Why scheduled posts don't publish on time — inspecting WP-Cron with WP-CLI

A post scheduled to publish at a specific time doesn't go live when expected. A plugin's recurring email notification never arrives. This tends to happen on low-traffic sites, and there's a specific reason for it. Note: WP-Cron is WordPress’s built-in scheduling system. It sounds like the OS-level cron daemon, but the underlying mechanism is quite different. WordPress’s WP-Cron doesn’t work li...

I generated 207 MCP tools from an OpenAPI spec. Generating them was the easy part.

Every MCP server I've read that wraps a third-party REST API has the same shape: someone picked fifteen or twenty endpoints that seemed useful, hand-wrote a Zod schema for each, and shipped it. That works for about three months. Then the API adds a field, deprecates an enum value, renames a query parameter. The wrapper doesn't notice, because nothing in it is connected to the API's own descripti...

Stop writing glue code for telephony APIs

I've spent enough time in the trenches of software engineering to know that there is nothing more soul-crushing than writing 'glue code.' You know exactly what I mean—the thousands of lines of boilerplate, error handling, and webhook listeners required just to make two services talk to each other. When Bland AI first arrived on the scene, it was essentially another API you had to integrate. You'd...
