I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]:

> If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos.

Hopefully I did that?

Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub:

Anyway, if this shouldn't have been Show HN, I apologize!

This is super freaking cool. I'm curious how you feel about Austin vs Bay Area in terms of general quality of life, culture, things like that?

Related to culture, I moved to Austin in 2012 and that was the first time I saw a restaurant advertising that their water had no fluoride.

I suspect it will be interesting when people all realize too much fluoride is very bad and isn’t actually disinformation. It’s obviously not an intentional conspiracy to make people dumb but it happens to be outdated science to fluoridate city water at levels we do in the US.

This is factually incorrect. In fact recent studies show that up to 25% of cavities are still prevented by fluoridating water. On top of that, multiple Canadian cities are adding fluoride back in their water after 10 years of having it removed because of excellent evidence that the lack of fluoridation in the water is what led to the increase in cavities in those cities, since they had neighboring cities who kept fluoride in the water during the same period

It's factually correct that too much fluoride is correlated with decreased average IQ.

By "too much" a factor of > 10x western safe levels is meant and by "correlated with" is meant a slew of other heavy metals are generally present.

This comes from studies that look at places in China, in Africa, and elsewhere that have unusally high levels of fluoride and other elements naturally occurring in water or as a by product of other industrial processing going on.

Where the problem lies is in the "fill in the missing line" extrapolations that the anti-fluoride folk do to "conclude" that if really high levels of stuff in water makes you stupid and affects your health then it surely must follow that small amounts make you a bit stupid and a bit unhealthy.

This is despite no such evidence existing even given large western populations with meticulously kept water quality and health records in the UK, Canada, Australia, US, etc.

The G20 recommended fluoride levels are safe by all the evidence to date and work to decrease cavity rates.
