Let’s face it - trying to optimize code without a profiler is like trying to fix a car engine blindfolded while wearing oven mitts. You might eventually stop the smoke, but you’ll probably replace the windshield wipers instead of the piston rings. Today we’ll explore the world of performance profiling tools that act as our code cardiographs, showing exactly where our applications’ heartbeats turn arrhythmic. Why Your Code Needs a Fitness Tracker Before we jump into tool comparisons, let’s address the elephant in the server room....

Let’s start with a thought experiment: imagine if every chef was required to publish their secret recipes by law. The culinary world would either become a utopia of shared knowledge or descend into anarchy of copycat carbonara. Now replace “chefs” with “AI developers” and “recipes” with “model weights” - welcome to the main course of today’s debate. The Current AI Kitchen: Secret Sauces and Mystery Meat Modern AI development often feels like watching a magic show where:...

When Your Microservices Need Marriage Counseling Testing microservices is like keeping a troupe of drama-prone actors in sync - miss one cue and the whole production collapses. Through years of wrestling with distributed systems (and occasionally crying in server rooms), I’ve catalogued battle-tested techniques that go beyond textbook examples. Unit Testing: The Art of Surgical Mocking Let’s start with the foundation. A well-isolated unit test is like a perfectly crafted espresso shot - small but potent....

The Clean Code Cult: When Perfect Becomes the Enemy of Good Confession: I’ve written code so clean it would make a preacher proud. But I’ve also shipped code so hacky it would make that same preacher weep. There’s a time and place for both. While Clean Code enthusiasts (and I use that term affectionately) bring valuable principles to the table, their dogmatic application often chokes startups with technical debt disguised as virtue....

Pharo is like a time machine for coding - it lets you travel through your program’s runtime while it’s still running. This modern Smalltalk dialect isn’t just a language; it’s an interactive world where your objects live, breathe, and respond to every keystroke. Let’s explore why you should give it a spin, and how to get started without losing your mind. Why Pharo? The Short Story of ‘Small Talk’ Smalltalk began as a research project at Xerox PARC in the 70s, aiming to make computers as easy to use as children’s toys....
