I have a ten-year old MacBook Pro with an i7 and 16gb of ram. Just because this thing was a total beast when it was new does not mean it isn’t old now. works great with Ubuntu though. It’s still not a good idea to run it as a server though. My raspberry pi consumes a lot less energy for some basic web hosting tasks. I only use the old MBP to run memory intense docker containers like openrouteservice and I guess just using some hosting service for that would not be much more expensive.
I was on a holiday in the Cinque Terre in Italy with my wife a few years ago. Because of a rainy day we decided to take a train to Genua and visit some museums. At the maritime museum I randomly met an Italian coworker/coauthor from my research institute in Germany, who was visiting his family in his hometown with his wife.
