No more fillings as dentists reveal new tooth decay treatment | Society | The Guardian

TL;DR: Here’s how it works…

The new treatment, called Electrically Accelerated and Enhanced Remineralisation (EAER), accelerates the natural movement of calcium and phosphate minerals into the damaged tooth.A two-step process first prepares the damaged area of enamel, then uses a tiny electric current to push minerals into the repair site.

RECONSIDER — Medium

This thoughtful piece by DHH is the Basecamp ethos distilled down to a pithy rallying cry against startup & VC culture.

Part of the problem seems to be that nobody these days is content to merely put their dent in the universe. No, they have to fucking own the universe. It’s not enough to be in the market, they have to dominate it. It’s not enough to serve customers, they have to capture them.

What a Deep Neural Network thinks makes the best #selfie

TL;DR: the best selfies are from women, with long hair, often B&W, with letterbox-type borders. The included picture is the top 100 ranked images.

To take a good selfie, Do:

  • Be female. Women are consistently ranked higher than men. In particular, notice that there is not a single guy in the top 100.
  • Face should occupy about 1/3 of the image. Notice that the position and pose of the face is quite consistent among the top images. The face always occupies about 1/3 of the image, is slightly tilted, and is positioned in the center and at the top. Which also brings me to:
  • Cut off your forehead. What’s up with that? It looks like a popular strategy, at least for women.Show your long hair. Notice the frequent prominence of long strands of hair running down the shoulders.
  • Oversaturate the face. Notice the frequent occurrence of over-saturated lighting, which often makes the face look much more uniform and faded out. Related to that,
  • Put a filter on it. Black and White photos seem to do quite well, and most of the top images seem to contain some kind of a filter that fades out the image and decreases the contrast.
  • Add a border. You will notice a frequent appearance of horizontal/vertical white borders.

The US just lifted a crushing burden on prison inmates and their families – Quartz

Well done, FCC! Making changes that will positively affect the lives of those still incarcerated and their families, while punishing greedy businesses.

Currently, phone calls often cost more than $1 per minute including surcharges—creating outsize profits for the $1.2 billion prison phone industry. Prisons … sign exclusive contracts with companies like Global Tel-Link, and receive a cut of the proceeds from each call, creating an incentive to raise rates as much as possible.
FCC commissioner Mignon Clyburn called the current system—which drains the resources of the United States’ 2.4 million mostly poor inmates and their families—”untenable, egregious and unconscionable.”
