How I stay current in a field that changes daily – practical strategies for continuous learning without burning out

Practical automation scripts and tools I've built to keep my home network secure without constant manual intervention

Moving from 'trust but verify' to 'never trust, always verify' required dismantling years of security assumptions and rebuilding our entire authentication and authorization framework

Evaluating how LLMs are transforming smart contract vulnerability detection, their current capabilities versus traditional tools, and the most promising approaches for improving blockchain security.

How blockchain technology has evolved beyond digital currencies to create distributed trust systems that are transforming supply chains, identity management, governance, and more.

The day I first understood how Shor's algorithm could break RSA encryption, I realized our entire security infrastructure might become obsolete overnight - preparing for that future became urgent

How the shift from perimeter-based security to identity-centered Zero Trust architecture is transforming modern software development and why it's essential for today's distributed systems.

The first time I saw a convincing deepfake video, I spent an hour researching to convince myself it wasn't real - that moment changed how I think about digital evidence forever

The first time I deployed a microservices architecture to production, I thought our security was bulletproof - until a penetration tester showed me how they'd compromised three services in under an hour

Cryptography always felt like magic to me until I spent weeks trying to debug an SSL certificate issue - suddenly those mathematical incantations became very practical necessities

Years ago, I discovered a glaring SQL injection vulnerability in an internal application during a routine code review - that sinking feeling taught me that security isn't optional
