Recently I wanted to try to spin up a simple .NET Core application on my local cluster which I built in my previous article Manual setup of Kubernetes cluster on a Virtual Machine with kubeadm. The problem I had is that I needed to test applications in this cluster and deploy them as service in order to monitor potential issues behavior. As deployment of Kubernetes service needs an image to pull from, I decided to use dockerhub to push my test images, but they first needed to be created. ...read more

Initially I was trying to do this with YUI Compressor library which has .NET port as NuGet YUICompressor.NET which works fine in most of the cases, but in my case does not skip PRE tags which I use for code snippets on the website...read more

Caching common data like lookups for example in memory of your app can increase significantly your MVC web application performances and response time. Of course this data has to be periodically refreshed. You can use various approaches to refresh data including expiry, but this can create potential bottle necks in your application since once data expires, you will use request thread to pull the data, cache and serve the request response back...read more

Tracking conversion via pixel method is still widely used because of it's simplicity...read more

Limiting the number concurrently running Tasks is not that often requirement in a code, but eventually you'll find yourself in the situation that for the most likely performance issues you'll have to limit number of concurrently running Tasks. One of these situations is when you have long running operations in the Task. If you spin up to many Tasks you will seriously degrade your application performance...read more
