The red-brown of South Africa (and I guess Argentina and Australia too) are basically midway points of their lush green regions and dry desert regions.

South Africa is as green as neighbouring Eswatini (formerly Swaziland) in the east and south coast and almost as arid as the Namib desert in the far north west.

I suppose that's stating the obvious but still interesting. And could probably add some comment about how this shows the dangers of averages of any heterogeneous data.


One interesting fact is that the arid regions of Australia look much more red than most other deserts (which look more yellow, look e.g. at the Sahara or the Arabian Peninsula), this is due to the high concentration of iron oxide in the soil of many inland areas of Australia - in other words our sand basically contains a little bit of rust :-D

Edit: a more scientifically correct explanation can be found here: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/200...


Does that mean if you have acid rain, it reduces back to iron?


Acid rain oxydizes. Reduction is the oposite chemical reaction.


Ah, thanks. Then I misremembered my high school chemistry from 25y ago. I thought rust (the verb) is oxidation and that when you add an acid, it would be reduction (to get back the iron).


Acid / base and oxidize / reduce are mostly orthogonal. Acid / base is about moving around protons while oxidize / reduce is about moving electrons.

There's a table here: https://www.vedantu.com/question-answer/acid-base-reactions-...


"Acid" is from Latin acidus (sour, sharp, tart) by way of French.

"Oxygen" is a word invented in 1777 by Antoine Lavoisier, from the Greek oxys (sharp, acid): same thing!

Lavoisier also invented "oxide" from ox(ygène) + (ac)ide.


I think the mode (after coercion from millions of colors to a smaller number of buckets) would be more meaningful than the mean.


You're right, averages in mid-sized and large countries are pretty much meaningless


Absolutely love this. Thanks so much.

Is there a way to stream this playlist to my Kodi box. Maybe with an m3u file?


Great idea! Here is the m3u file for streaming purposes: https://locserendipity.com/78RPM.m3u


Wow, playlist up and running great on Clementine for Linux, thanks!


Awesome!


Fantastic. Thanks for the quick addition.

I had a similar problem recently, but it was self-inflicted.

Try changing the status of the "Beta: Use Unicode UTF-8 for worldwide language support" checkbox.

You can see this option by going to Settings and then: All Settings -> Time & Language -> Language -> "Administrative Language Settings"


> Every event-driven architectural pattern I've read about can quite easily fall apart and I have yet to find satisfying answers on what to do when things go south.

Just a kind request from someone living in the southern hemisphere not to use "south" as a synonym for "bad" or "fail".


I'm a quantitative finance / actuarial programmer. I've flipflopped between the programming and business side a few times in my life. At one stage I was in the Actuarial Valuations team, responsible for the periodic valuation of a set of life insurance books. Timelines were very tight, input data was a mess, the products themselves were complex. This wasn't easy stuff. During valuation time all of us were on edge.

But for some reason, being interrupted then didn't cause nearly as much damage to my mental house of cards as they do now, where my day job involves translating messy actuarial spreadsheets to code.

I can't put my finger on it. Both tasks were complex. Maybe the fact that actuarial valuations (like most financial roles) are based on spreadsheets and you have a visual model right in front of you, or accessible within a few clicks. I think that relieves some pressure on the mental model.

Programming, on the other side, even with all the IDE tools like a watch list and call stack, seems to require a larger mental stack, given the same complexity in another field.

Side note: work from home has been a dream come true in terms of the disappeance of interruptions. But I do miss the coffee breaks with colleagues (or what others would call water cooler conversations).


In general, genetic differentiation in populations of India is low (0.26-1.7%), but overall genetic differentiation in 18 mixed populations of India is higher (2.23%), similar to the largest single study on 16 tribal groups from central India (2.18%).

This is exactly why I despise it when I people say "things go south" then they mean "get worse" or "north of" when they mean "better".


I'm now in the habit of typing the opening backtick, ctrl+shift+v to paste some line of code, then having to WAIT a second or 2 and then type the second backtick. That usually formats it correctly. But I'm also very quick on the backspace and retyping the closing backtick, which is sometimes necessary.

Starting a new chat with someone in your organisation that you haven't chatted to is also annoyingly slow. This one I keep forgetting. So I search their name in the search bar, choose the hit from the dropdown and immediately start typing, only to notice that my initials 10 keystrokes didn't register, because the new chat was still initialising.

I'm curious, do you touch type? I'm also at about 100wpm, but only thanks to learning to touch type.


Do you have a link to the other channel? Thanks


I think it is the Computational thinking course (MIT 18.S191 Fall 2020) https://www.youtube.com/playlist?list=PLP8iPy9hna6Q2Kr16aWPO...
