Junior developers

The last months I had to do a lot of coaching. It made me realize that it’s really hard to teach someone something you have done for years. You sometimes forget what it' is like to be a junior, you just can not understand why, what for you seems like “the simplest fundamentals”, is hard to grasp for someone else.

Some rules that I try to apply:

  1. Do not take over -  It can be really hard sometimes to not take control of the mouse and keyboard and show them what to do. But we all learn the most from our mistakes, so let them try some stuff, if it fails you can fix it together and they will understand why it didn’t work.
  2.  Show the path– Try to direct them to the path of the solution without revealing it. Draw things and have conversations, ask questions such as “what do we want to do now?” or “what do we want to accomplish?” or “What is the error we are getting? and what should we do to fix it?”
  3. Be ready to learn – I learned something from every person I worked with. Don’t judge too fast just because the idea comes from a junior developer.

.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...
