Lessons from Go: Keep Calm and Use the Byte Array

Along with error handling and the lack of generics, the prevalent use of byte slices evoked resistance at first, but I quickly got used to it.

Musings on Go and Generics ...

I feel like I am the only person in the Go programming community these days, who hasn't expressed an opinion about the latest generics proposal. I wish, I could say that the reason was just a lack of time. Yet, what I really wanted was for the hype to die

Go Tip: Copy a Reader Into a Writer

Something so simple, and yet, so easy to forget right when you need it. How does one exhaustively read from a Reader and write to a Writer at the same time? One way is to set up a []byte buffer, use to read a chunk from the Reader, write the

A Crystal in Go’s World

Imagine a programming language with the ergonomic syntax of Ruby, the speed of execution of C, the concurrency model of Go, and last but not least, a compiler that performs null checks at compile time. Sounds like a dream? Well, this language exists, but chances are, you haven’t heard

Using Gohack for Temporary Modifications to Go Module Dependencies

I started programming Go right at the time when the topic of modularization heated up. Of course, we all know how it all played out with Go modules. They are here and they are (IMO) great. I have spent a significant amount programming Python before virtual environments were really a

Reflecting on My Experience With Go, One Year After

In my little more than a year day-to-day developer experience with Go, I have so far learned three things: I can change my entire view of how programming works, even after 12+ years of doing it in one form or another. People are blaming Java for all the wrong reasons

Simple Immutable Builders in Go, Using Value Receivers

Even in a simple language like Go, concurrently updating mutable state is like playing with fire. Take this piece of code, for example: l := content.NewLoader() l.PageCount = 5 c := l.Load(bytes) Can you be sure that what you are loading is actually going to contain five pages? What

My Reasons to Consider Go Coming from Java

I hate listicles, and I am highly hoping that this doesn’t become one of them. Yet, I somehow felt the need to write down the reasons why I am giving Go a second (or maybe, third 🤔) chance. To the Java developers out there, searching for a new weapon of

My Baby Steps with Go

Last week, I made my first tentative foray into Go programming. My company uses Go in a couple of projects, but although I have heard many positive things about the language, so far I have tried to stay away from it. The mere thought that Go is a 21st Century
