From unique to cleanups and weak: new low-level tools for efficiency ❤️

An overview of two new features in Go 1.24’s garbage collector: runtime.AddCleanup and weak.Pointer. Cleanups work similarly to finalizers but avoid some of their issues by not reviving the objects they are linked to. Weak pointers allow referencing objects without stopping them from being garbage collected.

Go Structs and Interfaces Made Simple 🔨

In this blog post, we'll demystify Go's structs and interfaces, exploring how they differ from classes in traditional OOP languages and why Go's approach leads to more maintainable and flexible code. Whether you're new to Go or have been using it without fully grasping these concepts, this guide aims to make these foundational elements click.

Faster interpreters in Go: Catching up with C++ 💪

PlanetScale is a popular cloud-based MySQL hosting service that uses Vitess, a MySQL scaler built with Go. This article tells the story of creating a virtual machine in Go to work with the SQL ASTs generated by their SQL parser—and how it performs as fast or even faster than MySQL’s C++ implementation.

Faster shuffling in Go with batching 🔨

Random integer generation is a fundamental operation in programming, often used in tasks like shuffling arrays. Go’s standard library provides convenient tools like rand.Shuffle for such purposes. You may be able to beat the standard library by a generous margin. Let us see why.

More predictable benchmarking with testing.B.Loop ❤️

Go developers who have written benchmarks using the testing package might have encountered some of its various pitfalls. Go 1.24 introduces a new way to write benchmarks that’s just as easy to use, but at the same time far more robust: testing.B.Loop.

Using Signals With Go 📆

Signals are asynchronous messages delivered to processes to inform them of events such as interrupts, crashes, or termination, or to initiate specific actions. Most programming languages provide mechanisms to catch and handle signals — for example, to enable a program to shut down gracefully — and Go supports this as well.

Where and why should you use iterators in Go? ❤️

In this article, I decided to dive in and figure out where iterators could actually be useful in practice. I read a bunch of articles, checked out developers’ feedback, asked around on Reddit — and in the end, I put together a list of cases where iterators can genuinely come in handy. I’ve already used a few of them in my own projects, and I’ve got to admit — it turned out to be pretty convenient.

Golang sync.Pool is not a silver bullet 📆

When it comes to performance optimization in Go, sync.Pool often appears as a tempting solution. It promises to reduce memory allocations and garbage collection pressure by reusing objects. But is it always the right choice? Let's dive deep into this fascinating topic.
