Infrastructure architect — enterprise IT, AI, and the systems underneath
I design and run the infrastructure that enterprises depend on: virtualization platforms, networks, identity, and increasingly the AI systems layered on top of them. This site is where I write it down properly — the reasoning, the configuration, and the failure modes that only show up in production.
Most of what I publish comes out of work I have actually shipped. Where I am uncertain, I say so.
Ask somebody how much text they just sent to an AI model and they will answer in words. Every bill, every limit, and every "this conversation is too long" error is counted in tokens — and tokens are not words. They are n...
NotebookLM is the agentic AI tool for people who have been burned by confident fabrication. Google's research assistant inverts the usual trust model: instead of answering from the open web or its training data, it answe...
OpenClaw is the agentic AI project that broke out of the developer bubble. Built by Peter Steinberger — the founder of PSPDFKit — it is an open-source, self-hosted personal agent that you talk to through the messaging ap...
Claude Code is Anthropic's agentic coding tool, and it makes a deliberate choice that sets it apart from the editor-based assistants: it lives in the terminal, not the IDE. That sounds like a downgrade until you use it,...
The gap between an agentic AI demo and an agentic AI system that ships is enormous, and the way to understand it is to look at the ones that made the crossing. This is a survey of agentic patterns that earn their keep in...
"Agentic AI" is the phrase that replaced "chatbot" the moment models stopped just answering and started doing. It is also badly overused — half the products wearing the label are a language model with a single API call b...
"Recover the vCenter password" is three different jobs wearing one sentence, and picking the wrong one wastes an afternoon. Before touching anything, decide which credential you have actually lost: The ESXi host root acc...
Retrieval-augmented generation demos beautifully and fails quietly. The gap between a notebook that answers questions about ten PDFs and a system that serves an entire organisation is not model quality — it is retrieval...
The CCR2004-1G-12S+2XS occupies an unusual position: twelve SFP+ ports and two SFP28 ports in a 1U chassis, at roughly a fifth of the price of the equivalent from a mainstream vendor. I have run a pair for eight months a...
Proxmox VE has moved from homelab curiosity to a genuine vSphere alternative, and Broadcom's licensing changes accelerated that considerably. But a Proxmox cluster designed like a vSphere cluster will disappoint you in s...
