Marco Marzaduri's lab

This is Marco Marzaduri's lab: a place where technology is taken apart piece by piece and explained in an understandable way. Here you will find articles on web development, networks and infrastructure, cryptography and artificial intelligence, written for people who want to truly understand the tools they use every day.

I work in cybersecurity, digital forensics and web development; I studied computer science and psychology. I believe technology should be explained with concrete examples, without simplifications that make it wrong and without jargon that makes it inaccessible.

How the articles are written

• They start from a real problem and arrive at a practical solution.
• They separate what is certain from what depends on context.
• They always end with a summary of the key points.
