Edge.js: Run C# code from node.js

Edge.js allows you to run .NET and node.js code in one process. You can call .NET functions from node.js and node.js functions from .NET. Edge.js takes care of marshaling data between CLR and V8. Edge.js also reconciles threading models of single threaded V8 and multi-threaded CLR. Edge.js ensures correct lifetime of objects on V8 and CLR heaps. The CLR code can be pre-compiled or specified as C# or Python source: edge.js can execute C# or IronPython script at runtime. Edge allows CLR languages other than C# or IronPython to be plugged in.

  • Download and install node.js from the node.js website(http://nodejs.org/download/)
  • Start a command prompt
  • Browse to the location where you want to run node
  • Install edge through the npm package manager: npm install edge

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...
