golang

This cheat sheet provided basic syntax and methods to help you using Go.

The Integrity Data Platform team at Grab rewrote a QPS-heavy Golang microservice in Rust, achieving 70% infrastructure savings while maintaining similar performance. This initiative explored the ROI of adopting Rust for production services, balancing efficiency gains against challenges like Rust’s steep learning curve and the risks of rewriting legacy systems. The blog delves into the selection process, approach, pitfalls, and the ultimate business value of the rewrite.

Performance comparison of different fan-in implementations in Golang

Write cleaner, stronger code by embracing Go’s error-handling philosophy.

What happens when we need different timeout durations for different endpoints? While implementing timeouts might seem straightforward at first glance, the most obvious solution fails silently, frustraiting both users and developers.

Implementing session-based authentication in Go web applications: a secure and efficient approach.

Patterns and Techniques for Writing High-Performance Applications with Go

An introduction to web sessions and implementing a secure session storage for Go web applications.

Let’s face it: modern apps often need to do a million things at once. If your app isn’t set up for that, it can feel clunky and slow. That’s…

An brutally honest behind-the-scenes story of writing a technical book from scratch. From burnout to unexpected wins, here's everything I learned while writing 100 Go Mistakes.

This post is my top list of the most common mistakes I’ve seen in Go projects. The order does not matter. Now, let’s imagine this Status type is part of a JSON request and will be…

Concurrency is HARD. Like, really hard. When you need multiple tasks running together, things get messy fast. I’ve spent years fighting with threads and locks in other languages, and man, the race…

A technical deep dive into debugging zombie processes in a Go and Docker setup, detailing how I fixed a server crash caused by Node.js process leaks in Stormkit. Learn about process groups, SIGCHLD handling, and using Tini for zombie reaping.

Go applications can implement graceful shutdown by handling termination signals (SIGTERM, SIGINT) via os/signal or signal.NotifyContext. Shutdown must complete within a …

We will see how to build a MapReduce system from scratch (its workings as well)

Server-Sent Events (SSE) is a powerful web technology that enables real-time, unidirectional communication from servers to clients. In this video we implemen...

When developers transition to Go from object-oriented languages like Java, C++, or Python, they often struggle with Go’s approach to types a…

Yet another article complaining about Go’s error handling.

In this article we will look into optimizing memory usage and CPU performance by designing our Go structs with the CPU word size and cache line size in mind.

Weak Pointers are not a new feature in Golang 1.24 because they were used internally. But now, they are officially available in Go 1.24. Generic Type Aliases...

This article dives into the internals of Go slices, exploring how the runtime efficiently grows the slice’s backing array. It covers the key strategies used, including growth factors, CPU word size alignment, and the size class allocation table, all aimed at optimizing performance while maintaining flexibility.

...at least for most use cases. Read on to find out more!

Go beyond the Go tutorials

I've recently found myself in a rabbit hole of Go major version bumping to v2. What started as a simple task quickly turned into hours of sifting through conflicting information. Should I use a v2 directory? Create a new v2 branch? What about creating a new repository altogether? The more

What does it mean to keep security in mind when writing Go code? Answering this question in one short article seems impossible. For this reason, we will narrow it down to a few specific practices.

Millions of developers love Go for its features, performance, ecosystem, and community. But there’s another, perhaps more compelling reason as well: Go is go...
