Why indoor lighting is hard to get right and how to fix it

Yeah, that's useful. Agree on the assessment, I want to give it a shot with one of those Bridgelux Vesta Thrive thing, it sounds like a good hobby project I would like to try. If that happens, I would do a post about it here.

By the way, I asked about this setup on reddit. They also recommend some custom COBs, which seems to be the most powerful solution, but isn't as practical as strips.

These look very promising, ship to Europe too. Extra high-CRI, very powerful (up 2600 lumens/m) and even dimmable? Wow. A bit unfortunate they are 5x times as much expensive than other high-CRI high-power led strip.

I am glad there are more posts on this. Are there any reasons why not considering LED strips at all? When installed properly with the "milk" diffuser and as indirect lightning, it's IMO quite nice and effective. They seem to be powerful enough (20W are about 2k lumens/m), can be also found in high-CRI variants, less expensive, various CCT, dimmable, etc. I am considering using them in a new house. Basically, multiple parallel led (with different CCT, like 3000, 4500, 6400) strips diffused against a wall/ceiling, controlled via smart relays and incorporated in home automation (so physical switches turn e.g. just the one with 3000K after ~9pm).

I need to validate that in some studio, but my hope is that e.g. 50 000 lumens from 6x4 meters of high-CRI led strips of 3 different CCT diffused over a wall would provide sufficient daylight feeling + not taking any space, generate many shadows, looks nice and are OK to look at. If I could make it dimmable, it would be great, but there seem to be tradeoffs (dimmable ones are not that good on CRI apparently).

Btw. there are apps for phones with light detectors which seem to follow basic physics (like showing 4x times smaller number when being 2x times further from the source)

I just recently made my new ugly but sufficient lumenator (a combination of 6400K and 4500K CRI95+ 1500 lumen bulbs, still adding additional ones) and also managed to integrate a WiFi relay with Smart Bulbs to my home automation via Home Assistant with a fallback to manual switch. I also tried Home Assistant's "flux" component which sets the colour and brightness based on the sun position but replaced that idea with being less-sun-dependent. I want to have a lot of light until e.g. 8 pm regardless of the light outside and only then start dimming to red. Simple variant is plain automation with templating, hard but dynamic.

Rationality for Kids?

I am so glad this question is here, as it's very relevant to my post a few weeks back about Effective Children Education.

By the way, I recommend following Duncan Sabien (referenced in the post below) on Facebook, he has good posts about children edu, e.g. his speech for sixth-graders (referenced by someone else here - but she picked the good parts).

As mentioned below, Julia Galef also sometimes mentions something related, but I haven't found much

Hi! This is an excellent answer, thanks.

[...] I believe your questions relate to all three ways to different extents (although the title of the post leans towards the HOW types of questions), but I found it useful to differentiate between these issues in order to make sure my time, money and efforts are well spent.

Needless to say that I updated significantly in the past month since I posted this question and the "Why" and "What" has definitely enlarged. I agree with you that it's a useful framework to have. I am also thankful for the practical bits. 

I would like to close my comment by emphasizing that children are born rational beings, but they just start taking over from their parents when they provide them with irrational explanations for things that happen or might happen to them (one of my favorites, here in Romania, is that "If you don't stop crying, a big bad wolf will come and get you"), or they build defenses of their own that are irrational, to protect themselves from being hurt. I believe that our job as parents is, therefore, to be rational and predictive in relation to them, as well as gently making them aware of the instances when they use irrationality to run away from their feelings.

I probably understand what you mean here and agree at least with my steelman version of your argument. But I would also like to emphasize that I want the "other" people which are important for me to understand "rationality" that I can't imagine how one could "born" with. Examples are all the great knowledge of giants on which shoulders we stand on (like, say, probability), "simply" results of scientific progress (like how minds work, or some biases...), or practical guide of "you are a human, try to work with that fact in the best way you can". At least I and virtually everyone I met didn't born with these, nor they figure all that out by themselves.

What was your reasoning for deciding whether to raise children?

The contraception didn't work and it was too late for abortion (should we choose it as an option)

It's great to see some support like this. Not just to help with motivation but also to see what the interest is. 

I think there is a massive opportunity in creating a k-12 home schooling version of Lambda School but targeted at general knowledge. Why not start by work together on it?

I am interested as it's probably clear from my question, but I don't think I would be a good fit to actually put it together (or that it would be cost-effective). I would be happy to put and run some structure which could do this. I should emphasize though that I am not trying to create a generic program for everyone as I think that's vastly harder and would IMHO need much more.

Hi. Thanks a lot for a really nice write-up. 

It seems that the regulations in the Czech Republic are actually legally "workable", i.e. it's possible to teach kids close to self-directed without having to do a lot of "compulsory curriculum" (i.e. my estimate is <5%). It also seems there is a "subculture" of families doing this and I managed to get to some people who know how to deal with this.

My conclusion is that there is no simple answer.

I don't aim for a simple answer and I do not expect there is some. But as I said, the current system seems so broken that just answering "try not to harm" is a good substitution question. Also, it doesn't really seem that kids would learn [and retain] that much [useful knowledge] compared to "watching youtube videos".

I have concluded that school reproduces more than knowledge. It reproduces culture.

It does so indeed, but that culture doesn't seem to be very worthwhile to me. I am rather tempted to risk this one, as the main thing it signals doesn't seem to be that problematic to pick up later. I.e. homeschooled kids doesn't seem to have issues when they want to switch to formal education, and at "worst" they pay a year or two of whatever-made-them-happy-or-stronger-in-other-ways for that (again, e.g. watching videos :-) ). I have read/heard this claim quite a lot, and I am less and less convinced that this aspect of schooling is positive.

I also think that some other benefits can be supplied in other ways and even more effectively. For example a good social network - it's vastly superior/efficient to learn a few networking skills and just infiltrate e.g. some organizations, events or groups with a "good network". It's unlikely that it's your random class that is "good social network", and e.g. I have literally 0 friends from my primary and secondary school (I have a lot from university though - but anyone can do the uni I did if they want).

The other aspect is that you and I might have good ideas about which curriculum would be best

That kind of links to my previous answer. I am coming to a conclusion that the skills I would like to convey are rather very generic, blurry and meta. I want to teach her how to understand herself, her motivation, discipline, emotions, reasoning, goals and drive, how to understand other minds and how to model the world. I want her to understand how she can learn by herself whatever she wants to learn. It really seems to me that if we don't want to learn something, then we should rather not learn it as we are not going to remember that anyway. And given the right tools and meta knowledge, we can learn almost everything in much shorter times than the "most common" path. Therefore, I don't really care that much about the "object-level" curriculum. I think (but that's still subject to a research) that the concepts important to me can be taught via mostly arbitrary picks in the real world (like nature or engineering) or just going outside and explicitly talk about that person kicking that soda machine. And I can't imagine how these skills would not be useful or universal to time, at least on ~15 years from now scale, as they seem to be useful since eternity. I can imagine my job going obsolete - but I would use exactly these skills to find and learn something else which would be the best in that time for me.

Thanks for the tip and links. Unfortunately, it doesn't show much in Prague (but still gives me a hint about what to look for even if some school isn't registered in the linked project).

The OP seems intent on designing/engineering the perfect education, when the answer from this perspective will require a lot of letting go.

Hm... I don't think I would have issues of having to do so. I am trying to understand how to think about this, and this simply didn't occur to me before. In fact, it seems that me and my girlfriend are currently rather at the side of trying to figure out how to do this in self-directed-way, but it's still in early stages.
