the inside mouth of a leatherback turtle is insane

I learn something on the ATF every day.

Sea turtles have terrifying spikes in their mouths but for an interesting reason

We can't unsee this.

Small excerpt from text :
"
Artist and biologist Helen Kairo, who runs the Anatomika Science Instagram account and website, drew some illustrations to explain why they have them.
She explains that they are anti-vomiting spikes.
‘Sea turtles swallow a lot of seawater while eating. As they eat, their stomach fills up with food and seawater.
‘They then vomit out all the water. The spikes trap food and keep it from coming out. It’s basically a reverse filter’.
"
And the sad truth about how us humans polluting the seas has a devastating effect as wel, on these sea creatures:
"
But plastic ocean pollution is having a dangerous effect on these creatures, adds Helen.
The natural spines in their mouth make it much harder for them when they ingest plastic as it often gets stuck.
‘This is why they have such a problem with plastic bags,’ she writes on Instagram. ‘It’s because the unique structure of their oesophagus makes it so that they can’t get rid of them.’

Schoolchildren cross the Panaro River in Guiglia, Italy, on a makeshift chairlift used for their daily trip to school in 1959. With the Guiglia Bridge destroyed during WWII, this rope-and-pulley lift became the only link between the town and the countryside on the opposite bank.

Even if you took the simplest possible model of a universe that's empty space except for a single body with mass, general relativity implies the existence of a black hole, a white hole, and a parallel universe.

Amogy , developer of a catalyst that converts ammonia into hydrogen and nitrogen has a contract with samsung heavy industries to develop a system that can be used for ships.
Amogy will become huge if they can pull this off. Hands down.
If they have shares and stock, it is a good idea to buy it.

Unlocking ammonia as a fuel source for heavy industry

Founded by four MIT alumni, Amogy is offering ammonia-cracking and ammonia-to-power systems for industries like maritime shipping, power generation, manufacturing, and more.

Small excerpt from text :

"
At a high level, ammonia seems like a dream fuel: It’s carbon-free, energy-dense, and easier to move and store than hydrogen. Ammonia is also already manufactured and transported at scale, meaning it could transform energy systems using existing infrastructure. But burning ammonia creates dangerous nitrous oxides, and splitting ammonia molecules to create hydrogen fuel typically requires lots of energy and specialized engines.
The startup Amogy, founded by four MIT alumni, believes it has the technology to finally unlock ammonia as a major fuel source. The company has developed a catalyst it says can split — or “crack” — ammonia into hydrogen and nitrogen up to 70 percent more efficiently than state-of-the-art systems today. The company is planning to sell its catalysts as well as modular systems including fuel cells and engines to convert ammonia directly to power. Those systems don’t burn or combust ammonia, and thus bypass the health concerns related to nitrous oxides.
"

"
Earlier this year, Amogy completed a research and manufacturing facility in Houston and announced a pilot deployment of its catalyst with the global engineering firm JGC Holdings Corporation. Now, with a manufacturing contract secured with Samsung Heavy Industries, Amogy is set to start delivering more of its systems to customers next year. The company will deploy a 1-megawatt ammonia-to-power pilot project with the South Korean city of Pohang in 2026, with plans to scale up to 40 megawatts at that site by 2028 or 2029. Woo says dozens of other projects with multinational corporations are in the works.

old facts from 1200 AD . . . translated from Latin in the Otia Imperalia

"Concerning serpents, the common people say that there are certain women who change into serpents, and they are thus distinguished: for they have a white band like a ribbon on their heads. Of course, it is to be wondered at, but not to be detested, that women are said to change into serpents. For we have frequently seen in England men changed into wolves during the lunations, which race of men the French call gerulfs, but the English call werewulfs: for "were" in English means "man," and "wulf" means wolf.
It has also been very common among Greek and Jerusalemite women, as they say, that they transform those who despise their lust into asses by a wonderful kind of incantation, so that the face of an ass endures the labor and burden, until the pity of the others relieves the punishment: which, however, I do not know whether to attribute to the delusion of the eyes of the beholder, or because demons run about the world and suddenly bring back the seeds of the things of which this is spoken, as Augustine says of the rods which the Magi turned into dragons."

here Augustine refers to the magicians contesting with Moses turning staffs into snakes

Isabella's sponsorship of Columbus' voyages was an outcome of the 1479 Treaty of Alcáçovas which prohibited Spanish ships from sailing in the Atlantic south of the Canary Islands. The Treaty prevented Spain from raiding Africa for riches and prevented Spain from sending ships to Asia. Isabella decided to sponsor the westward voyage in attempt to reach Asia without violating the treaty. On his first voyage, Columbus was directed to adhere to the treaty and stay north which meant his fleet couldn't take advantage of the trade winds, slowing the journey. On later voyages, the restriction was lifted.

Someone scrapped all of spotify and uploaded it to the internet, better have a LOT of storage avalaible, it's 300TB, that's a lot of music

 

[lxskllr]

You could probably delete at least 200TB for being worthless to get it a little more manageable.

They did some analysis of the archive and found some interesting trends

Backing up Spotify

We backed up Spotify (metadata and music files). It’s distributed in bulk torrents (~300TB). It’s the world’s first “preservation archive” for music which is fully open (meaning it can easily be mirrored by anyone with enough disk space), with 86 million music files, representing around 99.6% of...

annas-archive.org

• Spotify has around 256 million tracks. This collection contains metadata for an estimated 99.9% of tracks.
• We archived around 86 million music files, representing around 99.6% of listens. It’s a little under 300TB in total size.
• We primarily used Spotify’s “popularity” metric to prioritize tracks

That's crazy! I wouldn't have even been on the same continent if I had to order the listening genres.

 

[Charmonium]

It's pretty hard to comprehend 300 TB, but I think NSA has to use . . . petabytes for its *ahem* storage needs.

I am however still pleased by the animating consciousness. But I'm way too lazy to even look at that much music. First, I don't really listen much any more. But even when I did, "finding" what I wanted someplace was always my first choice.

 

[lxskllr]

I have 375GB if you include the spoken word stuff in my "special music" folder. That's just what's made it onto my computer. That might double if I put everything on it in every format I have.

 

[Charmonium]

Apparently, density is up to almost 30TB. Well 28TB but . . . . give it a minute . . . OK, now 30TB

A basic 5 bay raid enclosure only gives you 150TB

Woo-hoo - almost halfway there.

 

[Red Squirrel]

It's crazy how fast storage has evolved. I have like 40ish TB in my NAS spread across like 12ish drives which is small by today's standards. If I filled up my 24 bay enclosure with 30TB drives and did a single raid 5, would get around 673TB of space. To think, in the 90's, that many MB would have been a lot.
