Based on one of your comments clarifying what you're wondering, I don't know that this helps you in what you're looking for, but the "OMG particle" came to my mind. It was traveling at such high energy when it hit our atmosphere that...

If the proton originated from a distance of 1.5 billion light years, it would take approximately 1.71 days in the reference frame of the proton to travel that distance.

...

The energy of the particle was some 40 million times that of the highest-energy protons that have been produced in any terrestrial particle accelerator.

...

In the center-of-mass frame of reference (which moved at almost the speed of light in our frame of reference), the products of the collision with a particle in our atmosphere would therefore have had around 2900 TeV of energy, enough to transform the nucleus into many particles, moving apart at almost the speed of light even in this center-of-mass frame of reference. As with other cosmic rays, this generated a cascade of relativistic particles as the particles interacted with other nuclei.

I don't know if that cascade is the same as the Cherenkov radiation it produced, but that radiation is how they detected this particle, and it's interesting a.f.

It is emitted when a charged particle (such as an electron) passes through a dielectric medium (such as distilled water) at a speed greater than the phase velocity (speed of propagation of a wavefront in a medium) of light in that medium. ... Its cause is similar to the cause of a sonic boom....

I.e., (layman's understanding here) the particle, having a dual particle- and wave-like nature, is propagating through the vacuum of space "close" to the max speed of propagation of causality itself. As it encounters a medium, our atmosphere, it is going faster than causality itself can possibly propagate through that medium. But the energy is still there and isn't going to just vanish, so it has to split out into multiple particles that would, with their fraction of the original energy, then be able to propagate through the medium. Or something amazing like that?

Edit: My layman's understanding of Cherenkov radiation requires a bigger disclaimer, like a strike-through. :)

Am I understanding this correctly? NOLA was arguing that, since they tax satellite radio for listeners in their city, they should be able to tax internet streams for the same listeners? If so, I feel like the two things should be comparably applicable (if it weren't for the ITFA), but also fuck all the way off, NOLA government. Get fucked, seriously.

I hitched my horse to just what I consider the basics--zip and unzip--and that has made it easy for me. But I've been stuck on those.

Extract anything:

    
tar xf <archive_file>

  

Create a tbz2 archive:

    
tar cjf <archive_file.tbz2> <stuff to put in it>

  

(And tossing in a -v is pretty universal, if that's your thing.)

Some day, instead of commenting on a reddit Lemmy post, I think I'll Google how to tell it to use .xz.

Ok, you know what? Today is finally that day. It's just capital -J instead of lower-case -j! That's easy enough to remember, I guess.

Narrator who sounds just like Ron Howard: "It doesn't."

I interpreted it as teasing someone for duplicity when they are trying to hurt people (suggesting their outward behavior comes from inward self-loathing), and not talking about his body being weird but his behavior (as a dick).

I feel so lucky to have been here for this discussion today.

What would give them standing? They'd have to be an entity protected by the constitution to claim that protection was harmed. Is it this (Wikipedia)?

TikTok Ltd was incorporated in the Cayman Islands and is based in both Singapore and Los Angeles. source

I guess I've never thought about what makes an entity have rights here. Buckingham Palace couldn't just open shop here and start suing our government, right?

Eating plants isn't more expensive than eating meat, just eating plant-based attempts at mimicking meat.

haaaands

fuck yeah

Morocco?

This referred to CUNY a few times. I thought that, City University of New York, was a different institution, and I got the impression the article was referring to Columbia University as CUNY. Maybe I missed something?

That's exactly what I did with it.

(Spoiler in case anyone wants to guess first.)

This is at >!Emo's East in Austin, Texas. (I guess now they just call it Emo's.)!<.

An all-powerful, omniscient creator of literally spacetime itself, and he needs an anthill--one that is, on his scale, far smaller than a subatomic particle--to defend his honor against other anthills within the same infinitesimally small particle and to keep defending their anthill by some arbitrary and tiny point in this spacetime so they can have an everlasting party together outside of his pet spacetime, of which that anthill is, itself, constituted.

The secret is to throw yourself at the ground and miss.

I like the "private bathroom" ideas better, too, but, if you find yourself having to make a constant cleaning strategy work, after all, then on top of cleaning, perhaps try using something like Elimin-Odor after cleaning (if you didn't already try that) to specifically neutralize what she might smell? They claim it's designed to neutralize odors enough that a cat won't associate an "accident" spot with future bathroom eligibility.

And this article recommends waiting 48 hours to make sure it's dried enough to pick/scrape.

In anything, if you want to go

You need a montage! (Montage!)

Even Rocky had a montage (Montage!)

edit: Oh, but sorry, not under 30. I'll see myself out.
