Time will tell. LLMs are far from perfect, but I’m excited they’re here anyway. Not because of a silly promise to make me 10x more productive, but because they can solve some problems that were previously unsolvable.

Go's data race detector can miss possible races in executed code when using mutexes

The ultimate collection of practical Go programming examples, code snippets, and recipes for building efficient and reliable applications with Golang

Learn more about why developers end up with deeply recursive Go code and what can be done to mitigate stack exhaustion issues.

How many rabbit holes can tracing a system call in Go lead you into?

We rolled out Go 1.24 and saw a memory regression. Here's how we dug into system metrics, uncovered a bug in the runtime allocator, and worked with the Go team to help fix it.

Performance comparison of different fan-in implementations in Golang

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.

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

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

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

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