Knowledge Hub

Practical, opinionated reference material on the technologies enterprises actually run — written by people who operate these systems, not by people summarising vendor documentation.

How this is organised

Every topic opens with a Pillar Guide — one page that explains the whole subject in plain language. Around it sit tutorials, best practices, checklists, diagrams, downloads and FAQs. Start with the pillar; go sideways when you need detail.

AI

What artificial intelligence can and cannot do in a business, stated plainly — and how to tell the difference before you spend money.

Pillar guide

Machine Learning

Models that learn from your data: when they beat simple rules, what they need to work, and how they fail.

Pillar guide

AI Agents

Software that plans and takes actions rather than answering questions. What changes when a system can act on your behalf.

Pillar guide

Prompt Engineering

Getting reliable output from a language model — and treating the prompt as production code rather than a text box.

Pillar guide

RAG

Retrieval-Augmented Generation: making an AI answer from YOUR documents instead of guessing from memory.

Pillar guide

Model Context Protocol — the emerging standard for connecting AI models to your tools and data without bespoke glue for every integration.

Renting infrastructure well: what genuinely gets cheaper, what gets more expensive, and what to keep portable.

Pillar guide

AWS

Amazon Web Services in practice — the services worth learning first and the bills that surprise people.

Pillar guide

Azure

Microsoft Azure in practice, especially where it meets existing Microsoft estates and identity.

Pillar guide

Oracle

Oracle database and applications: performance, licensing and migration, without the sales framing.

Pillar guide

Docker

Packaging an application so it runs the same everywhere. The concepts that matter and the ones you can skip.

Pillar guide

Kubernetes

Running containers at scale — and an honest assessment of when you do not need it.

Pillar guide

Linux

The operating layer nearly everything runs on. Practical administration, not trivia.

Pillar guide

Cyber Security

Protecting systems and data against people actively trying to get in — including the new attack surface AI creates.

Pillar guide

Testing

Proving software behaves before customers find out it does not.

Pillar guide

Project Management

Delivering on time without pretending you knew everything at the start.

Pillar guide
