The more you know, the more you know what you don’t know

The last weeks I interviewed a lot of people that wanted to join our company, some of them just finished their studies, some had a few years of work experience and some had years of experience working in the IT industry. If I compared CV’s between these people I noticed that their are big differences on how people rate their skills. Especially young professionals seems to be very confident that they are experts in things like HTML, JavaScript, CSS just to name a few, until the moment you really start to ask some though questions about each of these topics.

It made me think about the four stages of competence:

  1. Unconscious Incompetence. You don’t know what you don’t know.
  2. Conscious Incompetence. Now you know what you don’t know.
  3. Conscious Competence. You can think your way through an exercise and perform it with some conscious effort.
  4. Unconscious Competence. You can perform the task without thinking about it. It’s automatic. It’s burned into your body and it just knows what to do.

This is not only applicable when you are learning a new skill, but also when you want to teach this skill to someone else.

A good example is driving a car, once you know how to do it, it becomes quick an unconscious competence. The problem is that when you have to teach it to someone else, you first have to move it back to your conscious memory before you can start explaining it.

Conclusion: humans are strange creatures Smile

.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...
