Huh?? F-35s don’t need radars.

Their primary purpose is bombing schools, hospitals, and refugee camps – none of which move or pose a threat.

I reckon posts linking to your self-hosted videos would work if they had an embedded video – if your instance set the <meta property="og:video ..."\> tags appropriately.

Also possible to make posts on your own instance which automatically federate to lemmy communities, as in this example which originates from a mastodon instance: https://lemmy.ml/post/41288461

Peertube is federated and self-hostable.

Even better, posts linking to peertube videos get an embedded video in the post:

Asbestos can be used by kids as chewing gum:

Wittenoom’s roads were paved with asbestos tailings from the nearby mines and workers went home covered in a layer of deadly dust.

Children played in the lethal mineral, and some even stuffed it in their mouths as a substitute for chewing gum.

Incorrect:

Þey don’t count because the actual spellings are:

Old school electro-mechanical rice cookers will stay latched in cook mode even while unpowered.

I’m just tempering the headline, not throwing doubt at the research and development possibilities.

I got excited about the headline, thinking they’d experimentally achieved ore-melting temperatures with a heat pump (“Ultra-hot heatpump breakthrough paves the way […]”).

I guess I perceive 270°C as below the threshold of “ultra hot”.

Later in the article it’s revealed that the breakthrough experiment is paving the way to the (as yet unrealised) ultra-hot (“Luo summarised various research fronts […] promising pathways towards the realisation of ultra-high-temperature heat pumps.”)

Still – 270°C! Commercial/domestic baking ovens when?

Probably yet another overblown headline.

Does anyone have access to the full text of the paper?

Abstract

Large-scale generative artificial intelligence (AI) is facing a severe computing power shortage. Although photonic computing achieves excellence in decision tasks, its application in generative tasks remains formidable because of limited integration scale, time-consuming dimension conversions, and ground-truth-dependent training algorithms. We produced an all-optical chip for large-scale intelligent vision generation, named LightGen. By integrating millions of photonic neurons on a chip, varying network dimension through proposed optical latent space, and Bayes-based training algorithms, LightGen experimentally implemented high-resolution semantic image generation, denoising, style transfer, three-dimensional generation, and manipulation. Its measured end-to-end computing speed and energy efficiency were each more than two orders of magnitude greater than those of state-of-the-art electronic chips, paving the way for acceleration of large visual generative models.

For over a century, the dream of efficiently concentrating low-grade heat into high-temperature industrial energy has been constrained by a stubborn ceiling: 200 degrees Celsius (392 degrees Fahrenheit).
Now, a team from China has shattered that temperature limit. Using a revolutionary heat pump with no moving parts, they achieved an output of 270 degrees with a 145-degree heat source to drive the cycle.

…so a modest but significant improvement has been achieved, but nowhere near the temps required for melting ore.

But maaaaybe, theoretically, with materials and technologies not yet developed, possibly by 2040:

In a December 5 article in Nature Energy, Luo summarised various research fronts, including his team’s thermoacoustic Stirling heat pump, as promising pathways towards the realisation of ultra-high-temperature heat pumps.
He also suggested development directions for materials and technologies needed for future ultra-high-temperature heat pumps operating from 600K to 1,600K, or 327 degrees to 1,327 degrees, saying these could be achieved by 2040.

you’d have to design your own charger and battery management modules

Just searched for “Sodium-ion BMS” on Aliexpress:

Asbestos kitties! Anyone cuddling these cats will be snuffling the asbestos fibres deep into their lungs; how much, depending on how weathered the AC sheeting is.

There are packages in the normal repositories; no need to use AUR:

…although I do notice there’s no jellyfin-web package (which is avaiable in archlinux).

As a rule, using AUR has caveats. We’d also need to know which AUR packages you are using to give advice there.

Fuck bucatini (unless it’s a baked pasta dish). The rest of the dish’s attributes are subjective.

Trollies are usually plastic-coated. If you’re gonna do this please burn it off first with a nice hot fire, then scrub off all the plastic residue before cooking food on it.

If it’s tin- or zinc-plated you run the risk of metal fume fever if you breathe the fumes, but once-off it’s probably not much of a hazard. Unless it’s cadmium plated (peculiar yellowish hue), in which case the fumes and residue are quite hazardous.

It’s also worth bringing a spanner to remove the castors – they’re usually decent quality and can be used for better purposes than a shopping trolley.

Not sure if any of this advice transfers with the programming analogy.

“Instructions unclear…”

Long answer, it’s true.
