Yes this is exactly what I said - it is only a cautionary tale for what we could do wrong, not basic biology.

It is important first to say that sleep optimization is not the only goal with these things, and understanding the timing of melatonin (not just melatonin suppression) is how we find out "when" the circadian clock is set. The circ

My office is not that big, so yes it is quite intense there. But, I should say just that system is capable of delivering >500 vertical melanopic lux (which is a metric based on holding the meter vertically rather than pointing "up&q

SAD and cancer rates go up somewhat with latitude, definitely by 35-40N. But it is complicated because it doesn't affect everyone the same way. e.g., most of Europe is living above 40N. In some cases, availability of natural light (due

Well there are several topics here: first, it is not true that people thinking about visual performance will find the right schedule for non-visual (circadian, alertness). The two are simply different concentrations, and we have chosen to f

Yes, we were looking at this quite a while ago. Lighting is a really hard business (especially residential) so we did not make the leap, and mainly have tried so far to work with people who are in that business. We thought back then that

I made a note about Blask's 2005 work below, which is the main work I was thinking about. We can say that constant light is bad for cancer. But as I'm refreshing my memory, winter can cut both ways. For some, it makes more darknes

A lot of them have very strict routines about going inside and using super-dark curtains at particular times. I've gotten to email some people above 60N and it is just what they do. In the old Aschoff "bunker" studies where p

Yes, I think that's right - we have 20,000 lumens in our office and it is pretty cool, except you can't see your screen when it's up all the way. I still prefer daylighting, because it changes the angle of the light and every

I think the seasonality data may be mixed, with more diagnoses in the fall and spring in human subjects studies. This particular claim was a hypothesis from Richard Stevens, with some experimental work that shows rapid cancer growth under c

(Michael from f.lux): this kind of thing is necessary for most buildings, because otherwise people don't get a "day" signal when they spend time indoors. Most of us spend >90% of our time inside. However, we shouldn't

I spent a lot of time with photos (Picasa) trying to do this peer to peer - this is what we built in the 2002 era. Here are a few issues: 1. Identity is hard to do on the LAN, so any sharing ends up using the cloud to figure out who has acc

Pulled from the comments (which are remarkably smart): "Upregulated p53 activity in humans is implicated in Huntington's disease. Which makes sense, since the symptoms involve early death of brain cells. So this isn't a panac

It's a mistake to think that checking a box that says "CC" means you actually had permission to issue a license. If you're selling stock photos, you need written consent for everything in the photo--artwork, brands, peop

SSD/HD ratio likely went up. Backing up a laptop ten years ago with 128GB SSD wasn't as hard a job as backing up 1TB SSD, which is now rather cheap.

Wonder what the number is with "noatime"? Every open is a write on a normal filesystem, but you can turn it off.

I have two of these cameras in a window, so they can see outside. Keeping the LED on all the time makes them useless at night from reflections, so I always turn it off. It seems really wrong that I am "allowed" to add electrical t

Maybe maintainers commit "early", merging other people's work that piles up at night, while contributors commit "late", at the end of the workday?

I really love Dropbox Paper, so I get part of the collaboration story. What I don't like is that it's so hard to share a file, or to send an image in a chat -- all paths lead to dropbox links instead. When I get a Dropbox link on

(f.lux author here): the initial part of this press cycle was effectively scare-mongering, and was later mostly retracted by Karunarathne. See https://www.theverge.com/2018/8/17/17724658/screen-time-blue.
