Last week we jumped right into the command line interface of Claude Code and vibe coded a tiny application. While this works with larger applications, it is not the best use of our tokens. If we do not want to explain everything every time we come back to Claude, we need a bit more structure. That will help us with fixing wrong technology choices as well. Let us see how easy it is to get more out of Claude Code.
AI tools for code generation are currently the hot topic. Wherever you look, there are tons of articles and videos that show you how easy it is to start and how you can turn your idea into an application. Between you and your dreams is just a 20$ a month subscription and then everything will be great.
If you are a bit more realistic, you know that there is a hook and that the advertised benefits are too good to be true. On the other hand, the tools are much better than what many sceptics say that claim the AI coding tools can only produce slop and are useless. As so often, these tools are multipliers and the better you know how to use them and what their limitations are, the better the results you get.
Over the next weeks I like to take a closer look at various parts of the development process using AI coding tools. I will use Claude Code, because I find it currently the most useful one.
If your Windows starts to crash a lot, you can try the following 3 commands to fix some common problem sources. The commands may take a while to run, but if they work, you save yourself a fresh installation of Windows.
When it comes to reporting, we often get some special requirements to transform data into a specific form. For one report we had a Workforce table with data that looks like this:
| EmployeeId | FirstName | LastName | DepartmentId |
|---|---|---|---|
| 1001 | John | Smith | 10 |
| 1002 | Jane | Doe | 10 |
| 1003 | Max | Miller | 20 |
For the report, we need to group the employees by DepartementId, and combine all employees with their EmployeeId into this form:
| DepartmentId | EmployeeFormatted |
|---|---|
| 10 | John Smith (1001), Jane Doe (1002) |
| 20 | Max Miller (1003) |
I run recently into this strange error with one of my Git repositories:
Pull Failed: error: could not delete reference refs/remotes/origin/HEAD: cannot lock ref 'refs/remotes/origin/HEAD': unable to resolve reference 'refs/remotes/origin/HEAD': reference broken error: vs-ssh.visualstudio.com:v3/* did not send all necessary objects
As I was refactoring a .Net project, I run into an annoying little problem that cost me a lot of time. While I could compile the project on my developer machine, it failed with this error on Azure DevOps:
[error]...: Error : This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them. For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is packages\SkiaSharp.NativeAssets.macOS.3.119.0\build\net462\SkiaSharp.NativeAssets.macOS.targets.
We use Seq to monitor our applications because it allows us to see all the important information at one place. Our customised dashboards help us to spot anomalies and corelate events without much effort.
Unfortunately, there is no direct way to clone a dashboard as a starting point to customise it for a different application. But with a little workaround we can get what we need, nonetheless.
If we committed something into a Git repository that should not be there, we could rewrite the history and make it look as it was never there.
I usually try to prevent rewriting the history, especially when I already pushed the changes. Then when we modify the past, everyone in the team needs to do some extra work to catch up.
If this is not a problem or the lesser evil, we can use the following steps to rewrite the Git history.
C# 11 introduced collection expressions (formerly known as list patterns) to .Net 7+. This little feature allows us to match lists by shape, not just by checking every position. Let us see how this can influence how we write checks.
Installing packages with Winget is usually a straightforward task. However, when it comes to PowerShell 7, we need a little additional option to get everything correctly set-up.
