Daddy, when I grow up I want to be a small basic developer

15 years ago I wrote my first program in Turbo Pascal. Nowadays if you have children and want them to learn programming check out Microsoft Small Basic , which combines a simple (but powerful!) language and a rich set of libraries together with a friendly development environment.

The Small Basic language draws its inspiration for an early version of BASIC but it is actually based on the .NET Framework. Like the early variants of BASIC it is based on, Small Basic is imperative and doesn't use or expose beginners to concepts like scopes, types, object orientation, etc.

Even though it is based on the .NET Framework, it really is small and consists of just 14 keywords. In fact, there really isn’t a type system. You can create string and numeric constants and assign them to variables. Operations performed on these variables will be interpreted according to the content. All variables are global and are always initialized, so they can be used before they're assigned.

It’s very easy to build simple games and even share them with your friends by using the Silverlight player. I couldn’t resist to write some Small Basic programs myself…

.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...

I’m really bad at remembering emoji’s. So here is cheat sheet with all emoji’s that can be used in tools that support the github emoji markdown markup: All credits go to rcaviers who created this list.

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...
