3 ways of shooting yourself in the foot when writing applications in Go

I’ve been using Go for a few years now and today I want to share some experience. This post is about a few funny and somewhat not obvious bad Go patterns. This is 3 ways of shooting yourself in the foot when writing applications in Go. Channels overflow Among many other things, Go is great for its concurrent programming model. Goroutines, channels and packages from the standard library like sync offer a great experience when it comes to solving problems with concurrency.

Extending the Kubernetes API

Kubernetes offers various ways to add custom functionalities and to modify the way built-in features work. Today I want to talk about extending Kubernetes by using custom resources and controllers. Let’s take a close look at how to do that, but first a quick story! Why extending Kubernetes As I mentioned in my previous post, my journey on the cloud began with Google App Engine. As a developer, I was pretty happy with the path to production of the service.

The Certified Kubernetes Application Developer and Administrator Certifications

After a few years of daily work with Kubernetes, I decided to become a Certified Kubernetes Application Developer (CKAD) as well as a Certified Kubernetes Administrator (CKA). As I’ve just taken and successfully passed the exams, I figured this was a good opportunity for a story. My background experience My first steps with Kubernetes go back a few years ago, when I began experiencing on Google Cloud Platform and was amazed by how easy and fun it was to deploy applications on Google App Engine.

The Case of a Git Linear History

I recently left a team where I was the lead developer for about three years. I was regularly asked about why I wanted to keep the history of the git repository linear.

As a matter of fact, the question was also asked multiple times on StackOverflow, especially as What are advantages of keeping linear history in git or Git workflow and rebase vs merge questions.

Being the best, meaning having the best technical skills. It is not a rare thing for me to meet with someone, typically a fellow developer, who will give me the impression that having figured it all out about a technology is what makes you the best match for working on a particular project.

If your colleagues have presented robust and logical arguments, then it’s hard to defend your idea further. The thing is, if you really care about these ideas, then it is really a shame that it would only take a solid and well established argumentation for them to be rejected.
