John Lennon would have been 85 today. Imagine all that could have been if his life wasn't cut so tragically short. Here’s a short piano tribute. Imagine is an uncomplicated song but as close to perfection as humanly possible (in my opinion). #music #musicians #JohnLennon

In de politiek kunnen we giga van mening verschillen, maar feiten moeten leidend zijn. Wanneer er voor de ander geen feiten bestaan, verliest de waarheid. Wanneer de waarheid verliest, verliest de democratie. Daarom trekken wij een een grens.

We're so relieved to see Germany reaffirm its opposition to the dangerous Chat Control proposal--the one that would mandate mass scanning of communications. Germany's long been a solid champion of privacy, and the news that it was considering backing mass surveillance was alarming. 1/

WhatsApp-Konkurrent Signal droht mit Rückzug aus Europa
Signal gilt als einer der sichersten Messenger. Die App könnte aber in Europa vom Markt verschwinden, falls sich die Chatkontrolle in der EU durchsetzt.

It’s good we have data protection laws in Europe.
I am old enough to remember Americans were claiming that these laws would ‘hold us back’.

Will's post also shows a great use case for Python's structural pattern matching.
If the user can specify padding in many different formats, using `match` can validate the format during runtime and easily homogenise the structure.
What do you think of this alternative?
