AI Thread Summary
Today I learned that cleaning a white hat can be done with bleach cleaner, but it’s important to rinse it before wearing it again. I also discovered that "oyster veneering," a woodworking technique from the late 1600s, is experiencing a minor revival despite its labor-intensive nature. Additionally, I learned that the factorial of 23 (23!) equals 25,852,016,738,884,976,640,000, which interestingly has 23 digits, a unique coincidence among factorials. I found out that medical specialists often spend less than 10 minutes with patients, and that watching TV can contribute to weight gain. Other insights included the fact that a kiss can transfer around 80 million microbes, and that bureaucracy can sometimes hinder employment opportunities. The discussion also touched on various trivia, such as the emotional sensitivity of barn owls and the complexities of gravitational lensing around black holes.

I thought the literacy rate in Germany is virtually 100%. Are there really more than 7 million illiterates out of 80 million? Does this include people who were not educated in Germany?
What I've found on official websites (age between 18 and 64):
7.5 M - cannot read or write longer texts
2 M out of them with difficulties to read or write single words
13.3 M - deficits to read and write frequently used words
I haven't found figures about the structure of these numbers.
In total it is
82.2 M - total population
9.1 M - foreigners
17.1 M - immigrants

Their map left out Pennsylvania. Some Amish and Mennonites in Pennsylvania speak Plaut. Of course it's not nearly as widely spoken as Pennsylvania Dutch.

The entire situation is funny:
An Ethiopian born black man speaks to Canadian villagers in a rare coastal German language hardly understood in the rest of Germany.

(It's more than just a dialect and has once been spoken all around these coastal areas. Some words have a greater similarity with their English counterparts than with German words.)

Their dialect is rather pleasant. It reminds me of Afrikaans.

Pennsylvania Dutch has lots of words borrowed from English. But still in traditional communities the kids grow up speaking their dialect. Obviously they learn English in school. If I ever meet some of my distant Amish or Mennonite cousins in person, it will be interesting to see if we can communicate at all in German, or if we must use English. I think partial communication in German should be possible.

Oh well, now it's back to work. Thanks for posting.

Today I learned just how seriously scientists are taking the threat of LED screens to our eyesight.

http://www.dailymail.co.uk/health/a...indness-screen-time-blinding-kids-adults.html

I saw "computer glasses" in Fry's the other day but did not have time to look them over. I don't know if they are supposed to provide protection from the problem mentioned in this article, and if so how effective they are.

This seems quite serious for people who stare at LED screens all day. For now I will keep on using my old CRT monitor.

Interesting that it's short wavelength white light. I find LED flashlights uncomfortable, so am not surprised about the damage.

and driving at night into oncoming HID Xenon and LED headlights is sheer torture. I've written my congressman and senator asking for a ban on them.
And i sent the attached letter to NHTSA in response to a recent call for comments on some silly rule.

Do they bother anybody else, or am i just a grumpy old man with failing eyesight ?

TIL, that U.S. government scientists will not be easily muzzled.
U.S. government scientists go 'rogue' in defiance of Trump.
Employees from more than a dozen U.S. government agencies have established a network of unofficial "rogue" Twitter feeds in defiance of what they see as attempts by President Donald Trump to muzzle federal climate change research and other science.

Hundredfold? On what size of inventory? " Earlier this week Signet Classics ordered a 75,000-copy reprint of the book and the company spokesman says there could be more printings in the near future.

A previous version of this story said Kellyanne Conway was interviewed on Face the Nation by Chuck Todd. The show was actually Meet the Press." 75k? It's no longer required reading?

Today I learned that George Orwell died in creating his 1984 classic:

In 1946 Observer editor David Astor lent George Orwell a remote Scottish farmhouse in which to write his new book, Nineteen Eighty-Four. It became one of the most significant novels of the 20th century. Here, Robert McCrum tells the compelling story of Orwell's torturous stay on the island where the author, close to death and beset by creative demons, was engaged in a feverish race to finish the book

Today, I learned to stay off the north jetty of Humboldt Bay(coordinates: 40°45′53.06″N 124°14′05.01″W), when the National Weather Service issues a High Surf Advisory for Northern California after overnight measurements indicated a surf height of 27 feet.

Today I learned that just because Windows Update has been saying "Checking for Updates" day and night for 18 days (with the Windows Update service under svchost.exe showing 100% CPU for all of that time) that doesn't necessarily mean it's not making progress!

This morning, I found it had just applied 40 updates and had two more ready to install, after which it now reports it's up to date.

This is a Windows Vista system that I hadn't used since July, when I tried but failed to update it to Windows 7 (which it claimed should be compatible), getting some extremely obscure error in "specialization" processing after it had all apparently installed fine, probably due to the hard disk having been replaced a couple of years ago by someone who didn't do the right incantations to initialise the new disk correctly for Windows. Or perhaps the disk controller doesn't support the new disk properly. Or it's a side-effect of a known bug in the original CD version of the Windows 7 Update package to do with RAID controllers. Or something. Or something else. Grrr.

TIL about Göbekli Tepe while reading Sapiens: A brief histry of Humankind by Yuval Noah Harari.
It “is an archaeological site atop a mountain ridge in the Southeastern Anatolia Region of modern-day Turkey, approximately 12 km (7 mi) northeast of the city of Şanlıurfa.”
What is fantastically unusual about this site are the very large carved monumental structures built there
GobekliTepe.png

about 9500 BCE by hunter gathers rather than by farmers who archeologists have determined have built all other similar kinds of structures found so far.
