Use LinqPad for your Micro Benchmarks

I’m a big fan of LinqPad. Anytime I need to test a small code snippet, it is my 'goto' tool.

Today I was looking at the latest beta release where I noticed the following announcement:

LINQPad now lets you benchmark code with a single keypress! Simply select the code you want to benchmark, and press Ctrl+Shift+B. LINQPad uses the industrial-grade BenchmarkDotNet library as the underlying engine, while providing a customizable real-time graphical display of results. For a complete tutorial, press Ctrl+F1 and type benchmark.

Whow! That looks great! Let’s give this feature a try:

  • Download and extra the LinqPad 7 Beta release.
  • Run LinqPad.

  • At the top change the Language to ‘C# Program’.

  • Now paste the following code:
  • Select the 2 methods at the bottom and hit Ctrl+Shift+B.

  • LinqPad will ask you to download BenchmarkDotNet. Click Yes to continue.

  • After downloading the NuGet package and it’s dependencies, click ‘I Accept’ to accept the License conditions.

  • Now LinqPad will start a benchmark run and visualize the results.

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...
