What Is The Difference Between Single-mode and Multi-mode Fiber?
I recently wrote about the use of fiber optic cable for physical intrusion detection. In that post, I mentioned single- and multi-mode fiber. Here, I’d like to discuss the two types in more detail. This is a bit of a technical overview, so if you are looking for deep details or a non-technical explanation, this […]
Playing Cards at Work: Planning Poker Estimating

Twitter user @xaprb neatly summed up my own feelings when he tweeted When you’re fundraising, it’s AI [Artificial Intelligence]. When you’re hiring, it’s ML [Machine Learning]. When you’re implementing, it’s linear regression. When you’re debugging, it’s printf(). As someone […]
How Are Fiber Optic Cables Used For (Physical) Intrusion Detection?
Many of us have fiber optic cable that delivers Internet access to our homes or offices. But optical fiber cable can be used for more than high-speed data transfer. I’m not talking about artwork or illumination, but rather an important security application: physical intrusion detection. Optical fiber types In order to understand how this works, […]
Management in an Agile world
Agile was introduced to the world in 2001 after 17 men had met in Utah and devised the Agile Manifesto (agilemanifesto.org). It was created with a focus on software delivery projects and this is evident by its given title: Manifesto for Agile Software Development. However, in the intervening years, Agile has grown into something that […]
