Not sure my Raspberry is powerful enough to handle docker or if there are suitable images for arm. Otherwise sure that would be even simpler.

That is a neat solution, thanks for the link!

I use Radicale for a self hosted shared calendar and todo lists and notes with my wife.

I absolutely agree that many people should not have kids, and nobody should feel pressured to do so, and everybody should think twice before they do if it really is what they want and they are ready for that.

But as “general advice”? Sorry, but this is ridiculous.

Saying this as a fucking exhausted parent of a baby. It is hard, but absolutely no regrets here.

Of course if you value your own free time and activities above everything else, then yes, definitely please do not have kids. There will be no time for anything but baby care and the bare minimum household maintenance for a long time.
