There are a couple I have in mind. Like many techies, I am a huge fan of RSS for content distribution and XMPP for federated communication.
The really niche one I like is S-expressions as a data format and configuration in place of json, yaml, toml, etc.
I am a big fan of Plaintext formats, although I wish markdown had a few more features like tables.
What about thermostats for homes? I can absolutely feel a 2 deg F difference
I use °C and I feel the need to use the places after the decimal. Also, I feel nothing wrong about it.
Also, I use °F for body temperature measurement and need to use the places after the decimal and feel fine with it.
Also, when using °C for body temperature, I still require the same number of decimal places as I require for °F.
I am not saying that °F is not useful, but I am invalidating your argument.
Also whole degrees.edit: no, that’s wrong, there are thermostats that allow 1/10th of degrees (I only have old manual ones). I Still, you probably are not able to tell the difference between 20 and 20.1 °C. Humidity is far more relevant.A difference of 2 °F is 1.1 °C…
