If you want to get somewhere else, you must run at least twice as fast as that!” This quote, spoken by the Red Queen in Lewis Carroll’s Through the Looking-Glass (1871), became one of the most influential metaphors in evolutionary biology—and increasingly, in technology. Origins: From Victorian Nonsense to Scientific Theory Lewis Carroll (Charles Dodgson) was a mathematics lecturer at Oxford when he wrote Through the Looking-Glass. The Red Queen scene depicts Alice running hand-in-hand with the chess piece queen across a landscape that moves beneath them. Despite exhausting effort, they remain in the same spot. ...

Introduction: Shielding Critical Infrastructure Running 24/7 operations from a home base – whether it’s autonomous trading algorithms or personal management applications – demands more than consumer-grade network hygiene. We’ll cover segmenting your network to contain threats, hardening the perimeter (your router), and securing the endpoints (your servers – be they Raspberry Pis, standard PCs running Ubuntu, or even renterprise gear like Dell or IBM servers you might have… acquired). The goal is maximizing uptime and integrity while minimizing exposure (and money expenditure). Network Architecture: Segmentation is Non-Negotiable A flat network where your trading rig, your blog server, your smart lightbulb, and your personal laptop all share the same broadcast domain is an invitation for disaster. One compromised IoT device could become a pivot point to critical systems. Segmentation limits the blast radius. ...
