There is also https://www.rplumber.io/, which lets you turn R functions into REST APIs. Calling R from Python this way will not be as flexible as using rpy2, but it keeps R in its own process, which can be advantageous if you have certain concerns relating to threading or stability. Also, if you're running on Windows, rpy2 is not officially supported and can be hard to get working.

  Well, Mack the Finger said to Louie the King
  "I got forty red-white-and-blue shoestrings
  And a thousand telephones that don't ring
  Do you know where I can get rid of these things?"
  And Louie the King said, "Let me think for a minute, son"
  Then he said, "Yes, I think it can be easily done
  Just take everything down to Highway 61"

It appears that this expansion of the Amazon Prime music benefit comes with a major drawback: you can no longer play individual tracks, in some cases even if you have purchased them from Amazon. I discovered this trying to play my purchased tracks on my Sonos today. Previously, I could use the Sonos app to create a playlist of Amazon tracks of my choosing. Now I can only play Amazon-curated playlists, or play albums from start to finish. I'm only able to skip a certain amount of tracks in a short period of time.

It appears that Amazon concluded that it should fully adopt Spotify's business model and jettison users who still purchase albums or MP3s for download and self-curation, at least via Sonos. It appears it may still be possible to play individual tracks from Amazon's web-based music player.

Has anyone else experienced this?

"The flesh surrenders itself," he thought. "Eternity takes back its own. Our bodies stirred these waters briefly, danced with a certain intoxication before the love of life and self, dealt with a few strange ideas, then submitted to the instruments of Time. What can we say of this? I occurred. I am not...yet I occurred."

-- From DUNE MESSIAH, by Frank Herbert

Hmm, interesting. Assuming resurrecting you was easier than picking your brain, there would be the problem of you lying, both when you died and after you were brought back to life. How would they deal with that?

I guess they could just kill you again. But would the threat of that happening in the future deter you from lying at time of death, when you have nothing else to lose?

It seems like there would need to be system of proving possession of a password that would have to last 100 years. I have not thought through this kind of scenario (sorry!). Perhaps this has been considered before by those studying the problem in detail (e.g. science fiction authors)? What are the solutions?

As I understand it, this type of scrolling map visualization is something designed and implemented by Esri specifically for arcgis.com. See https://storymaps.arcgis.com/en/ for more examples and details.

It may be that the author of this article on housing developed the analysis, maps, and text but not the actual web UI. That might be something provided by Esri that is common to all of these "story maps".

It depends on what you're interested in. Admittedly, if you want, say, a global map of all hydrothermal vents, 500-2000m is not going to cut it. But the time and cost required to map the entire ocean with multibeam sonar is huge, on the order of 120 ship-years for the deep oceans and 750 ship-years for the shallow (<500m) continental margins [1].

Global coverage at 500-2000m resolution from satellite gravitometers represents a very cost effective middle ground between that huge effort and what is currently available, which is a patchwork of soundings that has gaps 10s to 100s of km thoughout much of the ocean. (See Fig 2 of [1]).

The article makes it sound as though the seafloor is virtually unknown outside of areas surveyed with multibeam sonar, which is a relatively small fraction of the seafloor. In fact, other technologies have been used to map the entire planet to a resolution of 15-60 arc second resolution (roughly 500-2000m). See http://topex.ucsd.edu/WWW_html/srtm30_plus.html for one such widely used, freely available dataset. What multibeam provides over extant dataset such as that one is much higher resolution.
