Phind–Your personal programming assistant

With the release of ChatGPT, GitHub Copilot, Amazon Code Whisperer just to name a few, large language models are the (new?) cool kid in town and you see a lot of new applications pop up trying to claim a part of this space.

If you are still in doubt if these tools can help improve your developer productivity, check out this survey executed and published by GitHub.

92% of developers already saying they use AI coding tools at work and in their personal time, which makes it clear AI is here to stay. 70% of the developers we surveyed say they already see significant benefits when using AI coding tools, and 81% of the developers we surveyed expect AI coding tools to make their teams more collaborative—which is a net benefit for companies looking to improve both developer velocity and the developer experience.

The list of available tools is long and keeps growing every day. Here are some I’m aware of:

And of course let us not forget ChatGPT.

Today I want to add another one to the list; Phind. Phind uses a combination of GPT-4 and their own model. This model should hallucinate less and write better code.

I started by asking to create a small application using the Task Parallel Library(TPL) DataFlow in C#:

 

Here is the exact prompt I was using:

I want to create a new C# application using the Task Parallel Library. This application should read a CSV file and parse it using multiple datablocks. Can you give me an example on how to write this code?
The result is not bad although the created example doesn’t take advantage of the TPL as it first reads all the data into memory. Let’s see if we can fix this:

This gives the following result:

The Main method became async and we got rid of the Wait() statement as we wanted. This is much better and more in line with the asynchronous nature of the Task Parallel Library.

Love it! (Of course it is again a good example on how you as a developer still need to understand what is going on so you can hint the AI assistent to improve the code).

Remark: You can also use it directly inside VSCode using this plugin.

If you compare this with what I got back from ChatGPT, the example created by Phind is much more what I expected:

And just for completeness, this is what I got back when asking the same question at GitHub Copilot Chat:

Not so good either. Phind is a clear winner int this example…

Remark: I tried some related prompts to further improve the result I got back from ChatGPT and GitHub Copilot but I never got to the result I got from Phind.

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) ...

Azure DevOps/ GitHub emoji

I’m really bad at remembering emoji’s. So here is cheat sheet with all emoji’s that can be used in tools that support the github emoji markdown markup: All credits go to rcaviers who created this list.
