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.
A degree Celsius is not coarse and does not require decimals in weather reports, and I suspect only a person who has never lived in a Celsius-using country could make such silly claims.
Consider that even if the difference between 15° and 16°C is not significant to you, it very well might be to other people. (Spoiler: it is.)
Then your suspicions are leading you astray.
They didn’t say a difference of 1K isn’t significant but the difference of 0.1K isn’t.
And since the supposed advantage of Fahrenheit is that it better reflects typical ambient temperatures, we have to consider relevance for average people. Hardly anyone will feel a difference of 0.1K.
That’s why European weather reports usually show full degrees. And also our fridges show full degrees.
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). 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…
