Golang

Recently, I learned that %#q in the fmt package wraps a string in backquotes. Unlike plain %q, which adds double quotes ", the # flag switches to backquotes `.

This little discovery led me to extend a go-critic check that didn’t know about it.

Have you found bugs in tools that you are using? Recently, while working on some google/go-github issues, I discovered a panic in go run. It happened when I forgot to provide an argument to the -C flag.

This article explains how I found and fixed the bug in go run -C and go install -C, added tests to prevent future regressions, and how my fix was successfully accepted into the Go repository.

How can a simple contribution to a library impact thousands of programs around the world? And why will this change become obsolete after the Go 1.26 release? These and a few other questions I’ll answer in detail in this post.

TL;DR: I replaced four helper functions (String, Bool, Int, Int64) with a single generic Ptr[T] function in google/go-github , affecting 10K+ projects. Ironically, Go 1.26’s enhanced new builtin will make this pattern unnecessary.

Recently, I started learning Beej’s Guide to Network Concepts but found that the examples were written in Python. However, I’m an engineer who loves Go. So, why not adapt it to Go? In this article, I adapt the chapter “5 Project: HTTP Client and Server” to the Go language. This will be useful for anyone learning network concepts who wants to practice in Go.

Golangci-lint v2 was released in March 2025 , bringing major architectural improvements and a cleaner configuration format. Despite being available for over seven months, adoption remains low.

If you are maintaining a Go project, now is the time to upgrade. This article covers why you should make the switch and provides a step-by-step walkthrough using a real-world project.

I accidentally discovered malicious programs in the Go ecosystem that impersonate legitimate tools such as the linter ldez/usetesting , the HCL editor go.mercari.io/hcledit , the official MailerSend Go SDK mailersend/mailersend-go , and many more. These programs are not very popular but are still used by some developers. By the time I wrote this article, I had reported the malicious repositories to GitHub support, and most of them have been deleted.

In this post, I show that contributing to Go repositories is as simple as contributing to any other open-source repo. This is a step-by-step guide to contributing to Go repositories. As an example, I use the main Go repository go.googlesource.com/go .

If you use an Apple Silicon (M1) Mac, you will hit an issue when downloading Go 1.15 or earlier via the dl tool.

Here is the solution:

$ GOARCH=amd64 go run golang.org/dl/go1.15@latest download
$ go install golang.org/dl/go1.15@latest
$ go1.15 version
go version go1.15 darwin/amd64

In this blog post, I will answer the question of how to enrich GitHub statistics to improve your job prospects by enriching your GitHub contribution graph.
