You can define operations on [-∞,∞) depending on a positive real number called the 'temperature' 𝑇 in such a way that:
1) for any 𝑇 > 0, you get a rig isomorphic to [0,∞) with its usual + and × . (A 'rig' is a ring without negatives.)
2) in the limit 𝑇→ 0, you get a version of the 'tropical rig', where addition is min and multiplication is + on [-∞,∞).
Yeah, the terminology is bad: the 'tropical rig' is a low-temperature limit! They should have called it the 'arctic rig'.

@chribonn @NorCal_Lynne @jeffjarvis @tomwatson Your analogy is wrong.
You don't need to understand PAL-M to watch TV usefully, but you do need to understand that different TV channels are operated by different companies, which are granted government monopolies on transmitting on those channels, and that they're heavily regulated and mostly ad-funded.
If you're sharing photos of mass graves in Ukraine or taking part in protests in Iran, you probably need to know if your instance is run by the Russian, Ukrainian, or Iranian government. You definitely need to understand that it's a possibility, and that the instance owner can read your DMs, trace your IP address, and take over your account.
Keeping activists, journalists, and their sources safe is more important than being appealing to the masses.
@larsks how about "hellsite"?

Need a disposable root server for quick experiments? `ssh root@segfault.net` (password: segfault).
@RaphaelWimmer @thc you might also like https://sadservers.com/ - you get tossed into a shell of a malfunctioning server and need to figure out the problem.
@mergerson We can't prevent racists from making instances and we can't prevent them from being racist on their own instances. Maybe we can enable people to avoid racist instances but how? Many people who say "I'm not racist" are pretty racist.

For anyone curious here is the very first toot I ever made on QOTO:
🇳🇱
@freemo@qoto.org
Some of my own work photographing and documenting the Orion Nebula. Old but a favorite. #Astronomy #astrophotography
@enkiv2 Thanks!
@NorCal_Lynne @chribonn @jeffjarvis @tomwatson I wasn't saying that you were dismissing them. You were saying that they were dismissing us, and I was saying that you were saying that.
@enkiv2 Is this documented anywhere?
@reiver @alcinnz That's a very interesting point, but I don't remember seeing much porn on the WWW in 1994, 1995, and 1996, when Gopher was still viable. Lots on Usenet, but none on the WWW, because (in the WWW and Gopher but not Usenet) the costs of the bandwidth were paid by the speaker rather than the listener, and porn would use rapidly a lot of bandwidth.
(So, predictably, the WWW is now full of speech that benefits the speaker rather than the listener.)
Even when viewing things that weren't images, WWW browsers were easier because they would use your `.mailcap` to launch `mpeg_play_motif` or whatever. There was no Gopher type code for MPEG, but there was a MIME type.
@enkiv2 To both? I have you confused with someone else?
@chribonn @NorCal_Lynne @jeffjarvis @tomwatson I don't align with the reasoning that excludes someone because they find a solution unintuitive either!
But mistaking Mastodon for a company is not finding a solution unintuitive. Is more like trivializing other people's efforts - in Lynne's example, trivializing them in order to dismiss them.
@reiver @alcinnz this comparison of Gopher from 1999 is worth reading: https://www.ics.uci.edu/~rohit/IEEE-L7-http-gopher.html
@hacks4pancakes I'm glad to see you here, and I'm glad is such a breath of fresh air for you!
@alcinnz Congratulations!
@mclare I see. I guess didn't want to be your first software-engineer employer, and have unrealistic expectations around hiring software people. Their loss!
@mclare These are structural engineering positions or software positions?
@freemo That really sucks. 😥
I hope you can find a refuge from the stress.
@freemo Because you ended with "Turkey".
