TIL what palynology is,

After reading this,

and checking here.

https://en.wikipedia.org/wiki/Palynology#:~:text=Archaeological palynology examines human uses,such example of this application.

"Ashes to ashes, dust to dust. Hmm, I could use that."

That Donkey & Tiger video made using "AI"; was using artificial intelligence to make the video really necessary?

No, but is anything in the arts really necessary?

What impresses me is how quickly I got sick of AI art once the novelty wore off. There's something ugly about it. But it is still in its infancy. In ten years, who knows?

I will further say that if I want art that is ugly, grotesque, and surreal -- and sometimes I do -- then AI art is unbeatable. Instant and it's free.

 

[jack action]

and [AI art is] free.

I highly doubt that.

TIL what a Nottingham algebra is and that
$$
\mathfrak{not}_n\cong \mathfrak{not}_\infty /\mathfrak{not}^n
$$
Good, that I'm a Forest fan.

 

[collinsmark]

and [AI art is] free.

I highly doubt that.

Well, @Hornbein might have a point here.

It goes without saying that AI is in its infancy, and that's certainly true in legal realms.

But there have been some early signs (and again, everything involving AI is "early" at this point in time) that AI generated works will not be afforded the same copyright protections as other works.

Here is an article as an example: US Copyright Office: AI Generated Works Are Not Eligible for Copyright.

So what does this mean? If an image is generated by AI (not just "AI sharpened," but wholly created such as diffusion based methods discussed in several PF threads), and you get ahold of such an image, you might be able do what you will with it and nobody's really going to stop you. At least in the US.

On the other hand, if your computer wholly generates an AI image, and some marketing department you've never heard of gets their hands on it and decides, without asking, to plaster that image on their cereal boxes, there's not much that you can do about it either.

Here's an article that's a little more recent: New US copyright rules protect only AI art with ‘human authorship’

So maybe it's kinda free? I speculate that rules and rights will become much less ambiguous in the coming years.

There is a sea otter that steals surfboards and rides them in Santa Cruz.

No one knows why.

No one knows why.

Because it's there !

And marine mammals are protected from harassment in California, so you can't easily take your board back (so I hear).

Sea Lions basking on harbor piers can be a big problem sometimes. They are used to people and don't easily scare away.

She was raised in captivity and released back into the wild so she probably has no fear of humans. And why surfboards? Maybe she got tired of body surfing. :) Or maybe she just wants a nice place to lie in the sun and knows she can chase off humans.

I'd guess what he had in mind is that the AI company is selling my data. But as I recall I didn't register.

I was thinking more along the line that it cost something to produce. Someone has to pay somehow.

I used to surf in Santa Cruz. I lived next to Steamer Lane, where the otters hang out. They float on their backs with a little flat rock on their chest, then tap crabs against them to break the shell. Do they have a special place where they save the rock whenever they dive again?

I will say that the Santa Cruz police would greatly sympathize with a surfer retrieving a stolen board.

There is a big rock at Steamer Lane where the sea lions live. They like to doze on their backs in the ocean with their flippers sticking straight up. One time while windsurfing I almost ran into some. If I had I would have fallen off the board and gotten bitten. As it was they chased me away barking.

Once at Waddell a sea lion body surfed a wave then swam away barking. Having a good time.

A Great White bit a surfer at Davenport. His board with the tooth marks was on display at Haut surfboards. Big. He paddled to shore and survived. He was an EMT and was able to tell the surfers how to save him.

TIL about the Big Chute Marine Railway. So simple, so cool!

TIL Chipotle has an autocado, a robot machine that processes avacados.

I like the word. Its almost autocad.

 

[Swamp Thing]

Today I learned that bacteria can share useful genes with each other "on the Cloud".

 

[Rive]

I like the word. Its almost autocad.

We have an old (cold war era) joke about that

Something about Russia producing a hair cutter automate for the military, and then bragging about it for the big rival
The first question: OK, but how does it work? Not every head is the same size and shape...
The answer: well, indeed... Not for the first time... ...

TIL that Willie Nelson and the President's son smoked a joint on the roof of the White House back when Carter was President. Carter confirmed it.

Too funny!!! Long story but when I was much younger, my uncle had virtually unlimited access to the busses of many celebrities for weeks or months at a time. On one occasion my family took Willie's bus for a um....1000 mile test drive for a week. Sure enough, we found a weed tray under one of the bed mattresses.

Reminded me of this song

 

[Hornbein]

TIL that megastar Mary Pickford sold locks of her curly hair. The curls cost $50 each, a fortune when a movie ticket was just over a nickel, and Pickford travelled with a suitcase of them. At the time of railroads and ships it wasn't unheard of to travel with twenty or so suitcases.

At a rally for The Great War she inspired the sale of five million dollars in bonds.

Let me try to understand this: Something you wrote 4 days earlier reminded you of something else?

 

[Ivan Seeking]

LOL! Yes, when I looked back at the thread. The thing about Willie smoking weed at the WH reminded me of the entire business. If he had left some of his weed in that tray I may have had more to tell.

Today I learned that

The accumulation and bursting of carbon dioxide bubbles can cause a peanut in a glass of beer to repeatedly float and sink. The process may help in understanding phenomena in Earth’s magmas.​

According to Michael Manga this is a thing in the bars of Argentina.

In a highly carbonated beer, such as a craft beer, the peanuts stay bobbing at the surface for longer than they do in a less carbonated beer, such as the lager they used for their experiments.

The Manga magma study is reviewed here.

One might hope that they mutually swore to refrain from the environmentally destructive practice of sowing the Earth with salt. Elephants would of course be banned as weapons of war. Will there be inspections to verify compliance?

 

[Frabjous]

The modern historical consensus is that Carthage was not salted. Regretfully, the North African Elephant has gone extinct.

TIL, from the NY TImes, its been hot recently:

[Mentors’ note: Stray text unrelated to the TIL theme removed]

 

[jack action]

TIL about an helicopter technique: autorotation.

[...] they go on to demonstrate how to safely land a helicopter when its motor has failed using a technique called “autorotation.” Using this technique, Gerry Friesen [...] even believes landing a failed helicopter is safer than landing an airplane with a busted engine.

[...]

As Destin explains in the video: "If the rotor blade quits turning you are going to fall like a brick – but helicopter pilots have a physics trick to keep that from happening." All it requires is a simple lever and a hell of a lot of practice. Check it out for yourself in the video below.

I like curry and I found an article in Science Advances on its early history about 2,000 years ago.
It has an interesting map of ancient spice availability:

The Dutch East Indies company grew fabulously wealthy selling nutmeg as a quack cure for the plague. The tree grew only on three islands in the Moluccas. Nutmeg traveled well and could not be counterfeited
