I think it depends. Lua is great for scripting - like when X happens do Y. I agree that makes sense for a case like Home Assistant. Sometimes you really want the result to be a data structure, not an interactive program, in which case I think more sophisticated configuration (as opposed to scripting) languages might be better.

Yes, there's a good example. Ansible would make more sense if its configuration language was Nix...
Oh, thanks for calling that out. I think I may have mixed up some of the frustrations I experienced at an old job.
I agree - YAML is not suitable for complex cases that people use it in, like ~~Terraform~~ and Home Assistant. My pet peeve is a YAML config in a situation that really calls for more abstraction, like functions and variables. I'd like to see more use of the class of configuration languages that support that stuff, like Dhall, Cue, and Nickel.
There is another gotcha which is that YAML has more room for ambiguity than, say, JSON. YAML has a lot of ways to say true and false, and it's implicit quoting is a bit complex. So some values that you expect to be strings might be interpreted as something els.
The equation for force of gravity is F = GMm / r² where
- G is the gravitational constant
- M is the mass of the planet
- m is the mass of the object being weighed
- r is the radius of the planet / distance between the centers of mass of two objects
The equation shows that gravity scales linearly with mass, and scales inversely with the square of distance. The article says K2-18 b is 8.6 times Earth's mass, and 2.6 times Earth's radius. So the weight of a 100 kg mass would be:
F = 100 × 8.6 / (2.6)²
which works out to a weight of about 127 kg, or 1.27 times heavier.
NixOS and Home Manager config both ways to get rid of the same thing
I use metric temperature when I talk to my kids. Now they give me a hard time when I give them a Fahrenheit value! Keeps me honest I guess. I've also got my oldest using a 24 hour clock.

Aw, thanks! That's high praise!
I used to organize a meetup for Javascript programmers. It was more about sharing information than about debate, but I think there might be overlap with what you want. The format was a regular meeting schedule once a month where 2-3 people would give presentations to show off what they've been working on, teach how to use a new framework, or whatever they were interested in. So in a way it has handing out information from on high, but I think because we had different people each meeting sharing their perspective there was a good element of exchange of ideas between peers.
Now it turns out that people need lots of leadership energy to create room for exchange of ideas. At the beginning I'd get about 6 people at each meeting, few of whom volunteered to step up in front of the group. So what I did was to show up every month, and talked about whatever topic I could come up with. At most of the meetings it was just me talking. When I did get other people to present it was through prodding and hassling. But people were interested enough in the material, and found enough value in just being in the same room with other people with similar interests that people kept coming back. It stayed small like that, growing slowly for maybe 2 years. But then we hit a critical point where there were enough people coming, and people were inspired enough that suddenly we were getting 30-50 people each month, and I had no problem finding volunteers to present. And it wasn't the same volunteers either - we had a good rotation of different people interested in sharing their ideas. That continued for another 6 years before I moved and passed organizer responsibility over to the next generation.
My point is that a club like this needs a lot of energy and attention. It's going to grow slowly. But it will grow if you keep at it, and put in the work. We reached that point where the group became sort of self sufficient in that I didn't need to be the one making presentations anymore, and I didn't need to actively seek out volunteers to present. But I still had to put in the work to make sure we had the meeting space available every month, show up to let people in, work out the meeting schedule, get food. Anything like this will die if there isn't someone holding it together through force of will. But it's worth it! It was a great experience!
I know you said you want your club to self-manage. But people need structure. If you ask people to show up and have stimulating discussion they're going stand around awkwardly not knowing what to talk about. Something like a presentation followed by discussion gives structure that helps people to open up, and explore their own thoughts. Or since you want multiple perspectives maybe a debate or a panel format would work better for you. Get 2 or more volunteers to talk about a specific topic. I highly recommend lining up panelists ahead of time - you'll have a rough time getting volunteers on the spot. If you prep your debaters ahead of time by asking them to present different views they might be less likely to simply agree with each other. Once your scheduled panelists get ideas flowing it will be easier to encourage attendees to step up to speak. You might have a debate or panel followed by open discussion, or rotating panel seats that people can step up to and leave as they feel inspired. But again, based on my experience I suggest being ready to be the one person standing up and debating yourself for maybe many meetings before the club finds a self-organizing energy.
I'm quite happy with Thunder.

Yes; he said that the real clothes itched, and Garak said that's the wool, you'll get used to it.
