Effective code reviews: ‘Buddy reviews’

Always looking for ways to improve the quality of our code, one thing I can recommend is the introduction of ‘buddy reviews’. You probably know the normal code review where maybe once a month, a technical lead or architect has a look at your code. Of course you have already moved on to another part of the code, so it’s way too late to fix all the detected issues (with an increasing technical debt as a consequence).

So let’s introduce the buddy review. It consists of meeting up with another team member informally (ideally before you check-in your code) and having a quick glance (5 - 10 mins) at each other's code at your desk or their's. This approach has the following benefits above the ‘formal’ code reviews:

  1. Problems are caught very early.
  2. You are always up to speed as to what is going on.
  3. Reviews are always very short because you are only looking at new code since the last catch up .
  4. Because the setting is informal - there is no nervous tension.
  5. They're fun! You can exchange ideas - regularly.

Go and try this with your team! You’ll not regret it.

.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...
