Learning to use Flexbox

Flexbox is a ‘new’ way to layout your html page in CSS. No longer you need to use things like floats and positioning for creating CSS layouts. Instead you get a more flexible approach that scales from smartphone to smarttv. Browsers start to pick up this technique, so it’s time that you start learning it.

From MDN:

When elements are laid out as flexible boxes, they are laid out along two axes:

  • The main axis is the axis running in the direction the flex items are being laid out in (e.g. as rows across the page, or columns down the page.) The start and end of this axis are called the main start and main end.
  • The cross axis is the axis running perpendicular to the direction the flex items are being laid out in. The start and end of this axis are called the cross start and cross end.
  • The parent element that has display: flex set on it (the <section> in our example) is called the flex container.
  • The items being laid out as flexible boxes inside the flex container are called flex items (the <article> elements in our example).

A great example that helps you understand the different settings of a Flexbox layout is the Build With React has a great flexbox editor.

Another one that I personaly liked(childhood memories) is a game called Flexbox Froggy. It teaches the concepts in an enjoyable and accessible manner.

Remark: Know that you can combine Flexbox with other layouting techniques that you used before.

.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...
