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...

How to Audit Your MCP Servers for Security Risks

TL;DR: MCP servers run with significant privileges inside AI agent pipelines, and most teams ship them without any security review. mcp-security-scan is an open-source CLI and GitHub Action that checks for credential theft patterns, data exfiltration, unsafe execution, and code obfuscation — and outputs a 0-100 trust score that integrates with AgentGraph's identity layer. The Moltbook breach l...

Cx Dev Log — 2026-07-29

Submain sits 12 commits ahead of main, ready for a merge that's been "most likely next" in every daily log for days. If you want to catch a project in a moment of tension, there's no better time. No commits added recently, but in the quiet lies the pushback of a pending decision. Current State Main holds strong at 380 passes and zero fails—a pristine test matrix. On its tail, submain c...

Rate Limiting Basics Every Developer Should Know

What is Rate Limiting? Rate limiting controls how many requests a client can make to an API or service within a given time window. It prevents abuse, ensures fair usage, and protects backend resources from being overwhelmed. Think of it as a bouncer at a club: only a certain number of people get in per minute. Why You Need It Without rate limiting, a single misbehaving clien...

Beyond Vibe Coding: Engineering Resilient AI Agents with FSMs, Privacy, and Cost Controls

Originally published on tamiz.pro. The era of "vibe coding"—where developers rely on large language models (LLMs) to generate entire applications through natural language prompts without deep structural oversight—is hitting a hard ceiling. While LLMs are exceptional at generating boilerplate, writing unit tests, or refactoring legacy code, they are fundamentally probabilistic engines. They lack d...
