I am a software engineer fighting data science, a marathon-wannabe, a hobby musician, a voracious reader, and photographer. I mostly write about building a strong developer culture.

Adding Version Information to Go Binaries

One of the things that I find really neat about Go, is the single-executable delivery model. For small projects, it’s as simple as dragging and dropping the built executable right where I need it. After some time, however, I might easily forget which version of my codebase a given executable has been built upon. If I have to revert a change, how can I make sure that I build from the right commit?

Implementing a Functional-Style Builder in Go

Go is definitely not the first language on my mind, when I hear the term “Functional Programming”. Yet, functions are first-class citizens in Go, and one can achieve a lot using higher-order functions (those that can receive and/or return other functions) alone. In this post, I want to demonstrate the use of functional constructs for implementing the well-known Builder pattern. Please, note that there are many ways to implement a Builder, and I don’t claim that mine is certainly the best.

“Once a language gets complex enough, programming in it is more like carving out a subset from an infinite sea of features, most of which we’ll never learn. Once a language feels infinite, the costs of adding further features to it are no longer apparent”. - Mark Miller An Open Letter To The Go Team About Try “Once a language gets complex enough, programming in it is more like carving out a subset from an infinite sea of features, most of which we’ll never learn.

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 choice, I am hoping that this will give you a bit of perspective. This is not a description of Go-specific features.

I felt that Go strikes the balance of robust systems programming and great performance with almost zero investment, and great developer experience. Some of that old 90’s feel, and a lot of that modern fantastic development practices. My Key Learnings after 30,000 LOC in Rust - Dotan Nahum - Medium For me, Rust takes a stroll over the memory lane above and picks and drives home the best experiences from all those languages — which is a

Deploying a Native Go Binary on Heroku

My company, KI labs recently held its first hackathon in our Munich office. My team and I went for a very cool mobile app idea that promotes healthy walking competitions among colleagues and friends. Though the app itself deserves a proper introduction, I will talk about it in a separate post. This time I will focus on one problem I experienced while working on the app’s backend part, written in Go.

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 version of C and has been explicitly designed from the start to not try to be much more than that, can make everyone coming from Kotlin and Swift pull a few hairs at first.
