Angular.js: using relative paths

One of the issues I had with Angular.js (but also with other JavaScript frameworks) is that URL’s you create on the client are relative to the server root address. This is fine as long as your application is hosted on the server root(e.g. www.myservername.com), but the moment you start using virtual directories(e.g. www.myservername.com/virtualdirectoryname ), you’re into trouble.

Let’s have a look for example to the following Angular service:

The problem is that when you host this service in a virtual directory, the HTTP call will be send to http://www.myservername.com/api/applications and not to www.myservername.com/virtualdirectoryname/api/applications as you would expect.

There a multiple ways to solve this issue.  I did it by rendering the rootUrl inside my ASP.NET Razor view. This url is generated by the server and embedded in the page:

Inside my Angular app, I added some code that read this value from the html and register it as a constant value:

This allows me to inject this value anywhere I need it, let’s have a look at the refactored service:

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cleaner switch expressions with pattern matching in C#

Ever find yourself mapping multiple string values to the same result? Being a C# developer for a long time, I sometimes forget that the C# has evolved so I still dare to chain case labels or reach for a dictionary. Of course with pattern matching this is no longer necessary. With pattern matching, you can express things inline, declaratively, and with zero repetition. A small example I was working on a small script that should invoke different actions depending on the environment. As our developers were using different variations for the same environment e.g.  "tst" alongside "test" , "prd" alongside "prod" .  We asked to streamline this a long time ago, but as these things happen, we still see variations in the wild. This brought me to the following code that is a perfect example for pattern matching: The or keyword here is a logical pattern combinator , not a boolean operator. It matches if either of the specified pattern...
