If you’ve ever spent an afternoon debugging a mysterious build error only to discover it was a typo in your webpack config, you know the struggle of choosing the right JavaScript bundler is real. The bundler landscape has evolved dramatically, and what was state-of-the-art five years ago might be causing you unnecessary pain today. Let me be frank: there’s no one-size-fits-all answer to “which bundler should I use?” But there absolutely is a right answer for your project, and that’s what we’re here to figure out together....

Writing Unmaintainable Code as a Strategy for Longevity: A Satirical Guide to Ensuring Permanent Employment

The Ultimate Job Security Hack Nobody’s Talking About Let’s be honest: in the world of software development, there’s an unspoken strategy that’s been floating around for decades. It’s whispered about in dark corners of tech forums and hinted at in Reddit threads at 3 AM. I’m talking about the art of writing code so deliberately obtuse, so magnificently cryptic, that you become the only person on Earth capable of maintaining it....

Introduction to Erlang for Building Fault-Tolerant Systems: A Practical Guide to Resilient Software

Why Your Systems Keep Breaking (And How Erlang Actually Fixes It) Let me start with something most developers experience at 2 AM: a production system failing because one small component crashed. You’ve probably added try-catch blocks everywhere, added retry logic that somehow made things worse, and created defensive code so convoluted that nobody dares touch it. Then you hear about Erlang, and someone casually mentions “letting it crash” as if that’s a feature, not a nightmare....
