ORMs - You're doing it wrong

ORMs(Object-Relational-Mappers), can’t live with them, can’t live without them. I always had a love/hate relationship with ORMs. No matter if it’s NHibernate, Entity Framework or a micro-ORM solution, it always feels like too much work just to get some data in and out a database…

Therefore it’s really important to use ORMs in the correct way. Jimmy Bogard has his own opinions about ORM usage and in his presentation ‘ORMs – You’re doing it wrong’, he shares his opinions with the world.

Nothing gets DBAs more riled up than a developer infatuated with an Object-Relational Mapper. ORMs work great at mapping from relational to objects, but can be a crutch. If you want to make your DBA (and your users happy), you’ll want to use your ORM intelligently. In this session, we’ll look at application patterns, ORM features and more to discover the right way of using your ORM. We’ll also look at when to ditch your heavyweight ORM and reach for a lighter one. Finally, we’ll cover why abstracting your ORM is evil and alternatives that give us more flexibility and maintainability in the long run.

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...

.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...
