If you spend May 2020 focused on other things than tech news, you may have missed the announcement of the Windows Package Manager. It took me a while to find this little gem and noticed that many developers had no clue either that this tool runs on their Windows 10 and 11 machines. This package …
Last week we worked with the main methods of the re module. However, when we need to be specific about the text parts we search, we miss a lot of the flexibility we can get from regular expressions. In this post we look at metacharacters and how they make regular expressions so powerful. This post …
This year marks a decade since I started to use NDepend to assess the quality of .Net projects. NDepend got much better over the years, and as far as I can tell, it is still the most flexible and versatile tool in this space. After using the current version for the last three months, it …
I waited a long time to explore regular expressions, then they tend to get complicated in no time. But for some problems there is simply no way around. Let us explore the basics and how we can use them in our Python code. This post is part of my journey to learn Python. You find …
Last week we run into a strange problem with our integration tests. On some developer machines everything worked fine, while other machines got errors like this one: System.InvalidOperationException : Cannot resolve scoped service ‘my.application.IOrderRepository’ from root provider. at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteValidator.ValidateResolution(Type serviceType, IServiceScope scope, IServiceScope rootScope) The problem It took us hours to understand what was …
If our application uses recursion, we may call the same function with the same values many times. When that function is side-effect free, we can save a lot of time by caching the result. And even better, in Python we can do that without much effort. This post is part of my journey to learn …

E: Release file for http://security.ubuntu.com/ubuntu/dists/jammy-security/InRelease is not valid yet (invalid for another 58min 27s). Updates for this repository will not be applied. How could that be? The difference of nearly an hour got me thinking about …
When we work with dictionaries that contains lists, we need to make sure that the list exists before we can add items. Or when we use a dictionary for counters, we must make sure that we have a value before we can increment it. While this can be done by hand, there is a much …
After 6 years it is time for an update of my tool list. At first, I thought that there are not that many changes, but after reinstalling my laptop I noticed that there are a few new entries that I would not want to miss. Do you know a tool that is not on this …
I had to do a lot of work with lists and dictionaries to solve the puzzles for Advent of Code. Here is my little cheat sheet for these two basic data structures from which you could also benefit. This post is part of my journey to learn Python. You find the code for this post …
