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.

SIGHUP Signal for Configuration Reloads ❤️

SIGHUP is a signal caught between two worlds. It was born from the physical "hang up" of terminal lines, and its original meaning — the loss of a controlling terminal — still applies.

How Go Scheduler Works 📆

Understanding the Go scheduler is crucial for Go programmer to write efficient concurrent programs. It also helps us become better at troubleshooting performance issues or tuning the performance of our Go programs. In this post, we will explore how Go scheduler evolved over time, and how the Go code we write happens under the hood.
