Electric cars charging infrastructure simulation

To get more insight into building electric car charging infrastructure I build a WASM tool to simulate different scenarios. In case this is also useful for you, you can access the published WASM here: Eletric cars charging infrastracture simulator

RamTreeMap

Searching for an easy-to-use tool to show the current RAM usage of a Windows PC in an intuitive way, I found a few options like:

However, none of those showed the data how I wanted it: in a tree map so that the image says it all.

So I created a C# .NET 10 WPF application using calls to the Windows kernel to get such an image. It was an opportunity to evaluate the current abilities of AI tools like Copilot and Gemini inside and outside the IDE.

My key takeaways on using AI for development:

  • The Good: AI tools are incredibly helpful for quickly getting a prototype up and running.
  • Prompting Tip: I highly recommend creating a single text file that gathers all of your application requirements before you start prompting. Feeding this into the AI keeps the generated code much more focused and aligned with your ultimate goal.
  • The Catch: Reviewing the code after generation is essential to avoid running into hidden problems. Furthermore, in my experience building this app, maintenance tasks like code cleanup, deduplication, and architectural tuning are still very much a human task.

I uploaded the tool here in case someone else is looking for something similar: RamTreeMap

Sauna in Austria

01.03.2026

I wanted a list of locations with saunas that I can visit in my free time, on vacation, etc. Since I couldn’t find one, I started creating one myself. It will change over time.

To make things easier I try to sort the locations a bit using these abbreviations:

  • LT = leisure time
  • HD = holiday
  • ? = unsorted
  1. Vienna
  2. Lower Austria
  3. Upper Austria
  4. Salzburg
  5. Vorarlberg
  6. Burgenland
  7. Styria
  8. Carinthia
  9. Tyrol

USB Stick Tests

Over time I gathered a bunch of USB sticks I wanted to verify if they are still good and usable. For such a task I found the tools f3probe and fio. So, I installed both on a Linux based PC (I used a Gentoo based one, but WSL based should also do).

After developing code for a new approach for handling parameters in FreeCAD I wanted to present it to other FreeCAD users to get some feedback. Of course, the code is still a prototype, but it is working and shows the intended workflow, so I wanted to know if other people also think something like this is useful.
