Software development is learning

In every software project you have 2 sides: the problem space and the solution space. The problem space is typically owned by a product owner, he or she knows the problem they want to solve. The solution space is owned by the developers, they know how to solve those problems.

Easy right? Unfortunately it isn’t so easy as it sound. Product owners don’t always succeed in explaining the problem (or describe a workaround instead of the real problem). As a result, developers don’t always get it right the first time and build the wrong solution.

The most important lesson you can take with you on any software project is that is all about learning. As you are learning nobody expects that you get it right from the first time. Instead somebody points you your mistakes and gives you feedback.

So how can we become better in writing software? Not by typing faster and certainly not by making no mistakes.

We become better by having better feedback faster. The key is shorter feedback loops; the compiler who tells you you’ve made a mistake, a smoke test that immediately warns you that there is a problem with a build, a user that gives feedback when you demonstrate a new feature, …

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
