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

It's ironic that Earth is running out of the second most abundant element in the universe. https://en.wikipedia.org/wiki/Abundance_of_the_chemical_elem...

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

Build an Air Quality Monitor with InfluxDB, Grafana and Docker on a Raspberry Pi https://news.ycombinator.com/item?id=19506983

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.
