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.

Go Cryptography Security Audit 🔨

Trail of Bits reviewed Go’s standard cryptographic libraries (ECDH, RSA, AES, HMAC, SHA, etc.). Only one minor vulnerability and a few informational notes (e.g., potential timing side channels) were found. All issues have been addressed in Go 1.24 and 1.25. The audit confirmed the high security and code quality of Go’s crypto stack.

You probably don't need a DI framework 📆

When working with Go in an industrial context, I feel like dependency injection (DI) often gets a bad rep because of DI frameworks. But DI as a technique is quite useful. It just tends to get explained with too many OO jargons and triggers PTSD among those who came to Go to escape GoF theology.

[ On | No ] syntactic support for error handling 🔨

One of the oldest and most persistent complaints about Go concerns the verbosity of error handling.
The Go team takes community feedback seriously, and so for many years now we have tried to come up with a solution for this problem, together with input from the Go community. If you’re wondering if your particular error handling idea was previously considered, read this document!
