In this blog post, I’ll guide you through a journey to understand how the Curiously Recurring Template Pattern (CRTP) is connected to the Strategy Pattern. We’ll start with the classic Strategy Pattern, modify it step by step, and ultimately uncover how CRTP emerges as its compile-time variant. Each step is only a small modification to the previous version, so you can follow along easily. Note: This blog post is not about CRTP itself. If you are not familiar with CRTP and its benefits, I recommend reading my previous post first. ...

Introduction In C++, the choice between static and dynamic dispatch can have a significant impact on performance, especially in hot paths. Understanding when to use each approach and how to optimize for maximum efficiency is key to writing high-performance code. This post will explore the Curiously Recurring Template Pattern (CRTP) as a way to optimize dynamic dispatch, focusing on practical examples and comparing the resulting assembly. Static vs Dynamic Dispatch Dispatch refers to the mechanism that determines which function implementation is executed when a function call is made. In C++, we have two types of dispatch: ...

Rust and Go are two modern programming languages that have made significant impacts in their respective domains. Rust shines in system programming, with a focus on memory safety without a garbage collector, while Go excels in simplicity and concurrent programming. Despite both being relatively young, these languages have key differences, even in how they handle range-based loops and loop variables. In this blog post, we’ll explore how Rust and Go differ in their treatment of loop variables, and a subtle but significant change introduced in Go 1.22. Even seasoned developers can stumble over these nuances, but understanding them can save you hours of debugging. ...

Saving Space on Your /boot Partition I recently ran into trouble because I followed the old advice of allocating only ~200MB for the /boot partition. While this might have been a reasonable choice a decade ago, when files were smaller and disk space was more expensive, it’s no longer sufficient for modern systems. On top of that, I’m dual-booting with Windows, which further complicates disk space management. Anyway, that’s the situation I faced. The next question was: how do I fix this? After searching online, I found several recommendations that suggested deleting initramfs-linux-fallback.img to free up space. While it’s a large file and might seem unnecessary, it’s not advisable to remove it without understanding its purpose. ...
