Quick tip: fix eID Viewer installation - a driver can't load on this device

I recently had to use the Belgian eID software and couldn't get it to work on the Windows 11 - it always failed with "A driver can't load on this device" - in the end I had to Turn off memory integrity setting (Microsoft support)

Since keeping the memory integrity setting is highly recommend - I would change the setting as soon as possible. Uninstall the Belgian eID software after you have used it and run pnputil to remove the faulty drivers so that you can enable the memory setting again.

Quick tip: retrieving raw, unprocessed files stored in Github

 The domain raw.githubusercontent.com serves raw, unprocessed files stored in Github repositories - think of it as GitHub's "direct file download" backend. Tools like curl, wget or Python scripts can fetch files directly using a specific url composed of the user name, repo, branch, folder and filename

curl -O https://raw.githubusercontent.com/[user]/[repo]/[branch]/[folder]/[filename] 

example: curl -O https://raw.githubusercontent.com/jorisp/tradingnotebooks/master/data/DJI.csv


You can also read these raw files form GitHub using pandas.read_csv

Quick tip: Upgrade yfinance as part of OpenBB

I have noticed that the yfinance Python package requires regular updating to keep it working. yfinance is also one of the core libraries inside OpenBB and you can upgrade it independently of the other packages using this command

pip install --upgrade openbb-yfinance

Divididend analysis of Telenor ASA using Jupyter Notebook

Cross posted from Divididend analysis of Telenor ASA using Jupyter Notebook

I just published the notebook dividends.ipynb on my GitHub repository jorisp/tradingnotebooks which shows how dividends contribute to the total return. This notebook uses the yfinance API to retrieve the data.  I used Telenor ASA (a Norwegian telecom operator) as an example.

If you are considering to invest in foreign dividend stocks as a Belgian investor, you need to keep in mind the double taxation of dividends. Even with a withholding tax applied abroad, the Belgian government will tax your dividend again at a flat rate of 30%.
