I was curious about the number of passengers carried by rail, so I looked at the wikipedia page. The US is 12th with 533 million passengers in 2019, which I find surprisingly low when compared to the population/size of this country. In France, same year, there was 1880 million passengers. I don’t think the rail infrastructure is well developed in the US, probably to the benefit of car infrastructure.

This seems too good to be true, but deserves to be tested. Apparently, you have the option to self host your web service, in case you don’t want to give them your data.

I use perlite to improve the drainage of the soil of my houseplants, I did not know it was used in construction and it was such a big market. So I was a little confused.
