It's even more to blame given that it stripped the NEA and IEEPA acts of legislative guardrails in 1987.

If you look at the solar radiation spectrum chart in the section "Why isn’t the sky violet?", you can see that sunlight is not evenly distributed along the visible spectrum--it emit more blue than red, and at sea level it's closer to evenly distributed. So the light that reaches the clouds is still mostly white light.

I think it may also relate to chromatic adaptation. To be white it doesn't need to be any exact absolute color just the color our brain sets our white point to.

Not answering this question but I found an interesting short paper about how at sunset and sunrise the color gamut of shadows doesn't fully overlap with the direct illumination color gamut due to the differences in the paths the light takes:

Source? There have been many articles on HN showing the RDA to be ~10x too low (something like 5,000 IU) and that the daily safety limit to be significantly higher than that (something like 30,000 IU).

Edit: for clarity I am not saying it is impossible to overdose on oral tablets, but rather that with most tablets 400 IU to 1000 IU and the safe limit so much higher than these, it seems like it would be extremely unlikely for someone to be taking 30+ tablets daily. Not impossible, but not easy either.

Here is a case study and discussion from a parathyroid surgeon:

https://www.devaboone.com/post/vitamin-d-part-2-shannon-s-st...

"There are people out there doing just fine on 5000 units of Vitamin D daily. I only see the ones who develop high calcium levels. But I see enough of them to know that this is not an exceptionally rare occurrence. I have been to lectures in which physicians have claimed that Vitamin D toxicity almost never occurs. In my experience, this is false. I have seen many cases of Vitamin D toxicity in people who were taking the recommended dose from an over-the-counter bottle.

Unfortunately, none of those patients were warned about the potential for Vitamin D to cause high calcium. They all believed that they were taking a supplement to improve health and that there was very little risk. Supplements don’t require prescriptions, and most do not have the warning labels that accompany medications. For Vitamin D, a steroid hormone, that may need to change."

joveian commented on Books I Loved Reading in 2024 thoughts.wyounas.com/p/bo... · Posted by u/simplegeek

joveian · a year ago

Although I'm only interested in a few books on the list I find it a nicely done list: a good theme and a good amount of detail per book. I can't do as well but these are my favorites this year(ish):

* Fur Trade Nation by Carl Gawboy - a graphical history of the Ojibway nation between 1650 and 1850. Not a hard history with detailed discussion of evidence and possibilities but more of a grade school style overview of the history and really well done as that. I do better with text than most but I still think this style communication has a lot of advantages and should be used more.

* The Birchbark House series by Louise Erdrich (historical fiction, starting at the end of the period Fur Trade Nation covers) - I've read the first three books and while they are aimed at children they have complex characters and themes (and also some cute animals and a focus on the kids). I read her book Tracks a couple of decades ago and liked it well enough to remember her name when I saw a few years ago that she has a bookstore in Minneapolis called Birchbark Books. Their online store has a great selection of books by indigenous authors.

* The Gift is in the Making Anishinaabeg stories retold by Leanne Simpson - Traditional stories retold with a few recent references. This one has a few ojibway terms but is in english while I also read Plums or Nuts by Larry Amik Smallwood and Michael Migizi Sullivan Sr. which is fully in ojibway as well as english and the stories there are more personal by the first author. They are chosen primarily for language learning reasons but they are also nice "slice of life" stories and I recommend it even if you aren't trying to learn ojibway.

* Heart Berries by Terese Marie Mailhot - The author has a breakdown and writes about it. A really rough read but well writen and has a lot of love for such a tramatic story.

* Bringing Joy: A Local Literary Welcome - I heard about Fur Trade Nation when it was first published and not widely available so I got it from the publisher at Fond du Lac Tribal and Community College and found this poetry collection and decided to try it even though I'm not usually into poetry. There were a couple that I will hopefully never forget and more that I enjoyed reading. I picked up What Book!? later thinking I'd try a bit more poetry but haven't enjoyed that one as much so far.

* A Space for the Unbound - Technically a game not a book but very story focused and in my opinion the best game story (by quite a bit) of any game I've played. Again some severe abuse depicted and also a lot of love.

But others use it as a signal. You are easier to track by the dishonerable with it. Meanwhile the honerable were probably not tracking as much [no way to tell but a reasonable guess]

joveian · a year ago

You might be easier to track with it, but it is not hard to end up with a unique signature anyway. I can already be uniquely identified, so sending "Do Not Track" only has potential upsides. I have seen websites that claim to honor it so it seems to be doing something and I wish they wouldn't remove it.

I wonder it I have this…

Both my parents go to bed around 1am and wake up at 7am, and so did all of my grandparents. My kids on weekends go to bed around 1-2am as well but do sleep in, and my average is about 4-5 hours a night…

As for me, I’ve had sleep issues all my life and found the only way to fall asleep within 20 minutes is to stay up until exhaustion. But lately I’ve been gaining back my time and pushing even further - once every one or two weeks I’ll skip a night of sleeping, staying up around 36 hours straight. I’ve been doing this for a few months now and have zero side effects so far. In fact I end up sleeping over 10 hours the next day without waking up in the middle (which /never/ happens otherwise).

joveian · a year ago

I've read that in cave studies when isolated from any direct indication of time people will naturally sleep longer every other day like this. However, I have severe sleep issues that leave me disabled and the main issue seems to be that I have a non-24 hour circadian rhythm and can't sleep outside the rotating times but in some ways my body is still synchronized to the sun (I do much worse when awake at night). So I worry you could also potentially end up with severe circadian issues unless you are completely blind, although if you always wake up at the same time whenever you do sleep that would hopefully help prevent issues. Sleeping in late some days makes circadian issues more likely.

Taking more than 20 minutes to get to sleep is not that unusual as I understand it. I think 30 minutes minutes is quite common even in people who sleep fine. 4-5 hours is very short though. One of my parents also slept little and there is also dementia on that side of the family (I have some memory issues as well already). I don't know how much previous gnerations slept but I suspect there may be not so benign genetic short sleep issues as well. At least some issues may have susceptibility and a triggering event, with tech making the triggering event more likely. That would be another question about benign familial short sleep, if it increases the susceptibility to more severe issues.

Thank you very much for the tip. I will try it out for a month, and let you know how it works.

The one I like to take at night is Life Extension 300mcg (.3mg) 6 hour timed release (they make a bunch of different ones), which is the closest to natural melatonin release of any supplemental melatonin I've seen, although it sounds like there is massive variation between people in how much makes it to the blood from a given dose. There are a couple of ways to use melatonin and for circadian use a small non-delayed dose earlier may be better (or use both):

https://circadiansleepdisorders.org/treatments.php#melatonin

I have had issues waking up more frequently when taking melatonin. It sounds like while not common this side effect is not that rare either. Based on my severe sleep issues (primarly circadian) I suspect that one part of "sleep issues" for many people is actualy waking up issues and that the detailed process around waking up has a bigger influence than is currently appreciated. I suspect one reason that melatonin is helpful is that it sets the stage for a better wake up, however if something causes this wake up procedure to start after not enough sleep it can be more difficult to get back to sleep. The delayed release seems to help quite a bit to limit the chance of this happening for me, although it does still happen at times. I'm not sure if melatonin is a particularly good option for staying asleep.

Unfortunately, there aren't particulary good options. Magnesium is the easiest and as effective as anything for me but unfortunately a high enough dose to be effective will also make me tired the next day. However, if your diet is low on magnesium then just increasing that some might help or possibly you won't have the issue with tiredness the next day. baclofen helps me but has issues and I certainly would not recommend it for your case.

A short (few minutes) nap mid day helps the circadian rhythm but longer naps can make it harder to stay asleep at night. If you nap for longer periods, multiple times, or later in the day that is the first thing I would suggest changing. I'm not sure what length causes more trouble but I think getting to sleep but staying asleep as briefly as you easily can is the ideal (though if you will naturally wake up after a bit longer that might be better than an alarm).

I also noticed covid made my already bad sleep worse when I had it (most likely covid, not confirmed by test; cold or flu usually give me better sleep for a day or two). However, I didn't notice any lasting issues (I still have severe sleep issues but it was just that first week of covid that they seemed to be different from usual). I wonder if it could be just your memory of how you sleep that changed after you noticed it due to the disruption. As long as you can easily get back to sleep and aren't staying awake for long it should not cause trouble and is not uncommon. If you feel rested there is nothing to fix while worrying about it or trying to change it could case worse trouble.

These are my thoughts anyway, hopefully something in there is helpful :).

This article makes me want to get a DNA test. In my family, it’s very common to sleep in the six-hour range. I personally sleep from 10 pm to 4:25 am every day, often waking up around 4:15 am before my watch vibrates to wake me.

If I sleep eight hours, I feel groggy, jet-lagged, and generally have a day where I’m slogging through molasses to get from one task to the next.

My wife has raised concerns about my sleep pattern, so I started using sleep-tracking tools like Fitbit and, more recently, an Apple Watch. She tracks her sleep too, and the big difference we’ve noticed is that I fall asleep within about two minutes, and my “sleep efficiency” using these tools is 98%. If I’m traveling and feel a bit jet-lagged, I can take a 20-minute nap (often without an alarm) and wake up feeling refreshed. She also seems to wake up a lot, most nights I "sleep like a log" and I only wakeup in the morning.

My mother has the same pattern but stays up later and sleeps about six hours into the morning. I used to do this too, but around age 23, I switched to an earlier bedtime and a consistent daily routine. When I became a “morning person,” I found I could code like crazy in the morning before “starting” my day, and this rewarding experience reinforced the habit.

I’ve tested this pattern in many ways, including not using an alarm (I still wake up around the same time for weeks at a time) and using a “light clock” I built with a Raspberry Pi to slowly brighten the room. Again, I wake up after roughly 6 hours and 20 minutes. Now, I use my Apple Watch to vibrate as a gentle reminder to start the day. On weekends, I keep the same schedule and use the extra time to read or hack away at side projects, often coding until the late afternoon when my wife protests enough that I need to stop and hang out or do my honey-do's.

About 10 years ago, during my annual checkup, my wife asked my doctor about this sleep pattern. The doctor asked me several questions, seemingly looking for signs of sleep deficit or dysfunction. In the end, he said I could do a sleep study but concluded, “If it works, don’t break it.”

As for productivity, I’ve found I can code effectively from 4:30 am to 8:30 am, then shower and work from 9 am to 6 pm without much trouble. I also practice intermittent fasting, typically eating only at 6 pm, with a protein shake around noon. This habit happened by accident—I realized breakfast slowed me down, and eating lots of carbs impaired my cognitive function and ability to code or handle complex tasks in the morning.

Before you ask, I generally don’t use caffeine or other stimulants. Occasionally, I’ll have one cup of coffee around 9 am as a social habit, but I recently stopped that again and actually feel better. I’ll most likely drop it again for a while until it sneaks back in again.

Thanks for sharing! I have severe circadian issues: non-24, except that my body also still in some ways follows the sun and I do much worse when awake at night. I've noticed that other accounts I've read from people who do well with around 6 hours of sleep are similar to yours and feature highly regular sleep times. From the reading I've done it seems there are a number of hormones involved in both sleep and waking activity with strong circadian rhythms and I suspect that at any given time I have a mix of night and day hormones. Of course people can famously fool themselves easily that they are getting enough sleep when they aren't but based on my experience I could easily believe it to be a superpower to have everything unusually well synchronized and I fully agree with your doctor's advice.

Talking about noise-cancelling fabric, I recently wondered:

Is it possible to noise-isolate my bed?

I live in a beautiful apartment in my favorite part of the city. But the neighbors on some nights are extremely noisy.

If I could noise-isolate my bed, that would be a huge quality of life improvement.

I was thinking about putting some noise absorbing material under the bed feet and a large noise blocking curtain over it. Like a baldachin or canopy bed.

Do you guys think that would work?

joveian · a year ago

I've looked into this before and unfortunately it is quite difficult to get good sound isolation and the answer is basically no. The really effective stuff is mass vinyl and as the name suggests it is quite heavy (and expensive). There are even some tents that musicians sometimes use for a few people to play together in a noisy environment that are hundreds of pounds without even being large enough for a bed. As I understand it, the mass is necessary for the best sound dampening. Also, once you get non-trivial sound dampening the way you let air in tends to be the easiest way for sound to get in. Even the heaviest cloth curtains would mostly help with any echos in your room rather than the initial sound itself. Maybe in some circumstances even minimal sound reduction would be helpful but you may also do a bunch of work and find it ends up making no difference.

Noise generators seem like the better way to start if you aren't using one already. I haven't tried many options but from the reviews I've seen fans are the best at this. In my experience ceiling fans do help quite a bit and there are some bedside noise generators that are fans but enclosed to limit the external air movement if the noise happens in colder weather. There are also some with speakers that play recorded fan noise, although beware of ones where the sample loops too quickly (I'm not sure what the best option to use your own recording would be). Unfortunately even getting to the point where you don't wake up (at least not enough to notice) may not fully remove the impact but it would still help quite a bit.
