The lru_cache decorator in Python's functools module implements a caching strategy known as Least Recently Used (LRU). This strategy helps in optimizing the performance of functions by memorizing the results of expensive function calls and returning the cached result when the same inputs occur again.

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.
Nowadays lots of companies choose engines like [Unreal](https:

I experienced some frustration with lack of other examples on getting select boxes to work on WPF DataGrid.
The first problem I encountered was that combo boxes did not have single-click to edit. That's what the Setters are for.
The next problem was that once I selected an item in a combobox, the combobox would not leave edit mode if I clicked directly into the next row. That's what the LostFocus and GotFocus events fix.
<!-- XAML -->
<DataGridComboBoxColumn
ItemsSource="{Binding Source=Blah}"
