Building Your Canonical Debug and Release Configurations

After nearly four decades of writing performance-critical C++ code, I've seen countless developers overlook one of the most impactful optimizations hiding in plain sight: the humble reserve() method.

Classic and modern prime number generators for C++.

In high-performance C++, design patterns are not just academic exercises – they’re essential tools.

As a developer who has spent countless hours wrangling with compilers, debugging memory leaks, and optimizing hot paths, I've developed both a deep appreciation and healthy respect for C++.

Modern C++, TypeScript, and Python are all multi-paradigm, and they’ve been quietly evolving powerful functional features.

Have you ever tried to compute statistics on a dataset so large it wouldn't fit in memory?

Whether you like them or not, passwords remain the primary line of defense for most online services.

With the official ratification of C++23, I've spent the last couple of years exploring what this standard brings to the table for developers like us who care deeply about squeezing every ounce of performance from our code while maintaining readability and safety.

In C++, the venerable std::iota algorithm has long served this purpose, but with C++20 and C++23 we gained even more powerful, flexible, and performant variants.

I've battled my fair share of mysterious crashes, inexplicable performance issues, and code that works perfectly on my machine but fails spectacularly in production.

In this guide, I'll walk you through starting your C++ journey from scratch, with a focus on free resources, practical learning paths, and the tools that will make your experience smoother.
