WSL–Getting started experience

Windows Subsystem for Linux (WSL) lets developers run a Linux environment directly on Windows, without the overhead of a traditional virtual machine or dual-boot setup. It is a very convenient way for developers to access and use a Linux environment. But although it not that difficult to get started, it can still take some time before you really understand how to use it.

If you also had some trouble to get started with WSL2, or even never took a look at it before, I have some good news for you. Starting from WSL 2.4.4(Pre-release), you get a ‘Getting Started’ experience. Let me show…

Getting Started experience

  • First we need to make sure that we download and install the latest pre-release version. You can find the correct installer here.
  • Download the msi file and run the installer.


  • After the installation has completed, open the freshly installed WSL Settings app:

 


  • The WSL settings app gives you easy access to a lot of the options that can be configured when using WSL2. This alone makes it a great addition to the current WSL2 experience. But there is more…

 

  • Click on the Welcome at WSL button in the left bottom corner. This will open up a new window that gives you easy access to some of the most common scenario’s when using WSL2.

 

  • This includes
    • Working across file systems

 

    • GUI apps

 

    • GPU acceleration

 

    • Networking integration

 

    • Distro management

 

  • It also gives you easy access to the Docker Desktop integration:

 

  • And how to debug and run applications in WSL2 through VSCode:

 

This is a great addition to the WSL2 experience and really helpful to get started.

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         ...

Cache stampede: when our cache turned against us

While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...
