There's PDRC, but we can't mass produce the "photonic metamaterials" that make it good.

It ought to be great. Takes no energy, sends heat through the infrared window back out into space where it came from.

I researched the topic and produced a short video on it: https://youtu.be/NVAcSgLZues

Purdue University produced a barium sulfate nanocomposite paint that has 98% reflectance in the desired band using a 150μm layer, cooling surfaces by 4.5C.

They say "yes, I admit it, this is all invalid".

No, they are a disclaimer that it's possible that the data isn't conclusive. Not the same thing as saying "it's all invalid".

Being immersed in solvent can't help with things like graphic arts and pottery.

Real effort, surely? Simulated reward.

Or scrolling represents a viewpoint, such as a frame, or a finger pointing at the document. Then it's the other way round again. You can't just declare what the metaphor is, it's arbitrary.

Yes, normally a BIOS setting on laptops I think. Before changing it I was hitting sleep constantly since they'd put it on F1, jammed up next to escape.

>something that never used to happen on Wiki

Revision deletion has existed for at least 17 years:

https://en.wikipedia.org/wiki/Wikipedia:Revision_deletion (page created in 2009)

Thanks for the info! I've literally never once seen that done on Wikipedia, and pretty much the first thing I do when looking at a new page is go to the history.

I've heard the exact opposite about India, which is that they export all their best quality tea.

But you're evidently talking about green tea, and maybe not black tea. That might explain the contradiction.

That would be high bandwidth and high latency, which might be the opposite of what's being proposed in the article. (It's difficult to be certain what's being proposed in the article. I'm fairly sure the article is about internet, beyond that point all is guesswork.)

I wrote a number of articles that try to address the many stacks of the application, transport, and OS layers. The best platform I can think of are the mid 2000's Symbian S60 phones, which were Real Time Operating Systems and used J2ME: https://inavoyage.blogspot.com/2026/06/how-about-new-java-ba...

There are new Java'based platforms that could build upon that, but chips today have so much processing power that they might think it's easier to develop a higher level language with more dependencies. But that leads to more maintenance if some package gets lost or broken.

As for the internet speeds themselves, It is similar to net neutrality but a voluntary guideline by the website developers: https://inavoyage.blogspot.com/2026/06/the-sierpinski-triang...

I also explore QUIC, but it's already implemented and not everything needs it, except higher bandwidth: https://inavoyage.blogspot.com/2026/06/5-things-to-lighten-d...

Once Android and iOS became the leading smartphone makers, code efficiency wasn't super important, because they hardware makers could add 10-20X the RAM. The competition between Symbian and iOS was a brief decade, but it actually made efficient code development interesting and beneficial for battery life. Since RAM got cheaper, even though it's expensive at the high end (HBM3e), it's a lot easier to develop with 4GB of phone memory than 4MB on the Nokia 7650 (2002). Those are quite extremes, but most symbian phones had a lot of features with as little as 32MB of RAM. https://en.wikipedia.org/wiki/Nokia_7650

Oh no, I drank 1 ml of saturated fat. Is it even still all bad for you? I thought I heard some detail about that recently ...

https://en.wikipedia.org/wiki/Saturated_fat

> A 2024 meta-analysis found that odd-chain and longer-chain saturated fatty acids were negatively associated with the risk of cardiovascular disease, including stroke.

https://en.wikipedia.org/wiki/Odd-chain_fatty_acid

>OCFAs are found particularly in ruminant fat and milk (e.g. pentadecylic acid).

(I don't know if that means most of the saturated fatty acids in milk, it's full of different varieties.)

Many a health or ethics rabbit hole can be bypassed with simple abstention. However, this is not good for 'content creators'. They need the controversy and rage bait for engagement.

With saturated fat the health authorities that have science but industry lobbying to content with, have told us to avoid the stuff because it clogs the arteries and invariably comes with cholesterol because animals. Arguably Ebola and AIDS are worse than a bit of saturated fat, however, it is a clear message, up there with 'smoking is bad'. Yet a vocal minority will spin this yarn about how wonderful saturated fat is. They are for real and tell the gym-going public all kinds of nonsense.

Yet a diet from before farmers started using copious amounts of synthetic chemicals placed saturated fat as very hard to get. There is no fat on wild animals, only on fattened up farm animals (and humans).

In these former times, meat of any kind was hard to come by. Chicken was saved up for, paying in installments for that special birthday treat. Meat such as rabbit was far more prevalent, the chicken was there for the eggs, not to be eaten as a snack in a lunchtime sandwich.

Hence, scale back all the modern day junk to the idealised peasant diet and there is no need to know anything about any modern day diet or nutrition talking points.

The peasants did not live for long, though, did they? Hard to say if and how the diet contributed, but just because people rarely ate meat then, for example, doesn't necessarily mean it's better for your health. Even if we could agree that people these days eat too much.

People talk about how we spent generations adapting to certain aspects of diet, and so following the habits of old is surely safer, but seem to forget that evolution only really "cares" about producing offspring, not your longevity, or quality of life in old age.
