I built a web interface for this type of nurse scheduling optimization. Mine uses CPLEX instead of the CP-SAT solver but the Python set up is very similar.
Here's the web interface to the nurse scheduler: https://forio.com/app/showcase/nurse-scheduling/
and here are some other optimization examples: https://forio.com/products/epicenter/example-applications/
Scott Alexander of Slatestarcodex provided some anecdotal evidence of this issue last year:
Last month I moved into a small cottage behind a big group house. The cottage is lovely. The big group house is also lovely, but the people in it started suffering mysterious minor ailments. Headaches, fatigue, poor sleep – all the things that will make your local family doctor say “Take two placebo and call me in the morning”. Using my years of medical training and expertise, I was able to…remain completely unaware of the problem while my housemates solved it themselves.
Aware of this research, my housemates tested their air quality and got levels between 1000 and 3000 ppm, around the level of the worst high-CO2 conditions in the studies. They started leaving their windows open and buying industrial quantities of succulent plants, and the problems mostly disappeared. Since then they’ve spread the word to other people we know afflicted with mysterious fatigue, some of whom have also noticed positive results.

WTA probably means winner-takes-all in this context.
I remember this Bret Victor piece from 2011 and I was thinking about it recently when Google announced Soli for the Pixel 4. https://www.cnet.com/news/project-soli-is-the-secret-star-of...
Soli and other gesture-based technologies seem like at least an incremental move to using motion that Bret Victor was advocating for in 2011.
Why would you use Monica at a start-up or Fortune 500 company? I had assumed that Monica was purely for personal use. It never occurred to me that a start-up, much less a Fortune 500 company, would use Monica for anything.
I've been using Monica for a couple of years now and I'm very happy with it for my personal network. It's a great tool to remind me who is connected to whom and what to ask about before attending a party. The online version is here: https://app.monicahq.com/register

There was a similar post on HN about four months ago describing an air quality monitor with a slightly different stack:

In 100 years will we wonder why recumbent bicycles took so long to catch on? MIT's David Gordon Wilson, the writer of the excellent book Bicycling Science, had been advocating for recumbents as a more efficient design to replace traditional modern bicycles for decades.

This article was published around 1999. Russel Ackoff mentions he is 80 in the article and he died in 2009 at the age of 90. The Systems Thinker started in the 1980s and discontinued publication in 2013. https://thesystemsthinker.com/about/
Scott Alexander (slatestarcodex) provided a meta-study and also described how reducing CO2 in his cottage reduced headaches, fatigue, and poor sleep: https://slatestarcodex.com/2018/08/23/carbon-dioxide-an-open...
After reading this, I got a Netatmo CO2 monitor like Scott and Gwern. I found that CO2 peaked in my bedroom at around 1500 PPM at 6 AM with the door closed and that I could keep it under 500 PPM with the door open or a window open.
Scott Alexander also suggests getting around 10 succulents, if you don't want to open a door or a window.
Edit: Scott Alexander also published these survey results from other people who experimented with reducing CO2 in their homes: https://slatestarcodex.com/2018/10/04/nighttime-ventilation-...
The elderly are generally more susceptible to internet fraud. Last summer the New Yorker had this story about how an 85 year old was scammed out of her life savings:

This is identical to how all other phone OS vendors work where the OS vendor pre-installs apps as part of their ecosystem. If you consider them crapware, then there are no major mobile OS vendors who don't install crapware.
iPhone preinstalls 42 apps, not all of which can be easily deleted: App Store, Calculator, Calendar, Camera, Clock, Compass, Contacts, FaceTime, Files, Find My Friends, Find My iPhone, Game Center, Health, Home, iBooks, iCloud Drive, iMovie, iTunes Store, iTunes U, Keynote, Mail, Maps, Messages, Music, News, Notes, Numbers, Pages, Passbook, Phone, Photos, Podcasts, Reminders, Safari, Settings, Stocks, Tips, TV, Videos, Voice Memos, Wallet, Watch, Weather
Android comes with 29 preinstalled apps, and like iPhone some of them cannot be easily deleted: Android Pay, Calculator, Calendar, Camera, Chrome, Clock, Contacts, Docs, Downloads, Drive, Duo, Gmail, Google, Google+, Keep, Maps, Messages, News & Weather, Phone, Photos, Play Books, Play Games, Play Movies & TV, Play Music, Play Store, Settings, Sheets, Slides, YouTube
All phones have undeletable apps provided by their manufacturers. For example, on iPhones you cannot delete Messages, Phone, Safari, Clock, Photos, Health, App Store, and Camera in a conventional way.
Like the iPhones, phones distributed by Google, starting with the Google Phone G1 in 2008, and continuing to the Nexus phones and today's current Pixel phones (Pixel 1, 2, and 3), have never had crapware.
Thanks for these graphs!
Your Voyager 1 graph [footnote 0, in the parent comment] shows two periods of particles-per-second drops to around 10 particles per second followed by a rebound and then a dramatic drop to 2 to 3 particles per second.
The Voyager 2 graph [footnote 2, in the parent comment] shows a single drop to around 17 to 18 particles per second and what looks like the beginning of a rebound. Wouldn't interstellar space be characterized by the drop to below 3 particles per second?
Is this the same issue we had with Voyager 1 where Voyager 2 is beginning the process of entering interstellar space but has not yet actually entered it? If not, why are the particle counts about an order-of-magnitude higher for Voyager 2 then they were for Voyager 1 in interstellar space?
A competitor of this business is compare.com: https://www.compare.com/
compare and cover seem similar. Both are short, common names that begins with a 'c'
This reminds me of an 1999 article in the New Yorker by Tim Ferris called "How to Predict Anything" https://www.newyorker.com/magazine/1999/07/12/how-to-predict...
Princeton physicist J. Richard Gott III has an all-purpose method for estimating how long things will last. In particular, he has estimated that, with 95% confidence, humans are going to be around at least fifty-one hundred years, but less than 7.8 million years. Gott calls his procedure the Copernican method, a reference to Copernicus' observation that there is nothing special about the place of the earth in the universe. Not being special plays a key role in Gott's method.
The Air Quality Index / Cigarette equivalence is based on the increased number of deaths from each.
One cigarette is equivalent to an air pollution of 22 μg/m3 for one day. Thus, an AQI of Particles (PM2.5) of 160 (today in San Francisco) is equal to 160 / 22 = about 7 cigarettes.

Scott Alexander wrote a short-story sequel to GATTACA on his blog SlateStarCodex this past summer that dealt with epigenetics and education that he called the GATTACA trilogy: http://slatestarcodex.com/2018/06/19/the-gattaca-trilogy/
“Well, you know how things are. We want to make sure we get only the healthiest, most on-point individuals for our program. We used to do genetic testing, make sure that people’s DNA was pre-selected for success. But after the incident with the Gattaca Corporation and that movie they made about the whole thing, public opinion just wasn’t on board, and Congress nixed the whole enterprise. Things were really touch-and-go for a while, but then we came up with a suitably non-invasive replacement. Epigenetics!”
Thanks for describing this. I wanted to see this debate myself. For others who might want to watch it, it's available on YouTube:
Slate columnist Sara Dickerman wrote a critique of pepper as a table spice a few years ago, while acknowledging its historical medicinal qualities, as the OP does:
Why should this brawny spice be kept on the countertop at all? Why not stash it in the rack with the fennel seed, the mustard seed, and the cinnamon—all the wonderful spices that add life to our food but are by no means all-purpose? I think we’d appreciate pepper's qualities all the more if we used it just for specific dishes, not universally.

Not sure what your issue with "hard to analyze" is. When compared to linear systems, nonlinear dynamical systems are hard to analyze.
Nonlinear dynamical systems, describing changes in variables over time, may appear chaotic, unpredictable, or counterintuitive, contrasting with much simpler linear systems.

This is generous of Kapwing.
It's worth noting that, outside the United States and a very small number of other countries, parental leave is usually publicly funded through taxes and administered through social security. Companies can then augment these social security payments.
For example, Austria, Brazil, Canada, Finland, France, Hungary, Italy, Ireland, Mexico, Norway, Poland, Portugal, Russia, Spain, Sweden, Switzerland, and Turkey all fund parental leave through social security. Others as well. https://en.wikipedia.org/wiki/Parental_leave
Both the Slatestarcodex article and the links you provided in your comment use deaths per 100,000. In fact, your article reaches a similar conclusion to Scott Alexander, that mortality is declining mainly because of smoking declining.
Scott Alexander (Slatestarcodex) had a post about this earlier this month:
http://slatestarcodex.com/2018/08/01/cancer-progress-much-mo...
The gist of the post was that cancer rates since 1990 have gone down primarily because smoking has declined, not because cancer treatment has improved.
The New Yorker had a good piece about people who attend the annual flat earth convention: https://www.newyorker.com/science/elements/looking-for-life-...
> He described the modern flat-Earth community as a confluence of three strains of thought. “There’s the conspiratorial,” he said. “It’s like, ‘That’s kind of weird with the moon landing. Maybe I’ll look into it. What else could they be lying about?’ ” The second is “the scientific-minded,” people who “just want to go out and do the experiments.” The third, Davidson said, “is the spiritual—people that want to say, ‘Wait a minute, what would happen if I took the Bible literally?’ ” In style and substance, the flat-Earth movement is a close cousin of creationism.
It's very difficult to change tipping expectations. Uber unsuccessfully tried to maintain no tipping through its app. After driver complaints[1] and pressure from NYC[2] and others, Uber added tipping.
