GitHub Copilot– Reusable prompts files

Yesterday I talked about custom instructions as a general way to influence the behavior of Github Copilot in multiple contexts(coding, testing, reviewing, ...) in VS Code. With prompt files you can go one step further, and provide specific instructions for a task.

Let’s give this feature a try.

Active the prompts file feature

First we need to activate this feature:

  • Go to File –> Preferences –> Settings.
  • Search for Chat and look for the Prompt files setting.
  • Click on the Edit in settings.json link.

  • The settings.json file is opened with a new chat.promptFiles setting already added.
  • Change the value to true. Now VSCode will look for prompt files in the .github/prompts folder.

 

    Creating a prompt file

    Now we are ready to add one or more prompts file to the .github/prompts folder.

    For every task you should create a separate Markdown prompt file.

    Remark: It is possible to reference other files inside your Markdown prompt file as well:

    Using a prompt file

    Now we can use our newly created prompt files.

    • Open the VSCode Copilot Chat window:

     

    • Select the Attach Context icon (Ctrl+/), and then select Prompt....

     

    • Choose a prompt file from the Quick Pick to attach it to your chat request.

     

    • Now we can either directly send the prompt or include other instructions.

    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) ...

    A complex system designed from scratch never works

    A few years ago, I worked as an architect on a big mainframe rewrite. I still count it as one of my failures. Not because the technology was wrong, but because I couldn't convince the management team to simplify the approach. Years later, the organization is still struggling to get the new system up and running. I left the project at the time, because I couldn't put my name behind an approach that would take very long and cost a lot of money without a working system to show for it along the way. Gall’s Law That memory keeps coming back to me, because it's a textbook case of Gall's Law playing out in real life. Gall's Law , from John Gall's Systemantics , states it plainly: A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works, and it cannot be patched to make it work. You have to start over with a simple system that works. What does that mean in practice,...
