I think of Yahoo as ‘The search engine that malware sets as default to get paid for referrals or something’.

A program such as the one in this post is a loop designed (intentionally or not) to run out of stack regardless of how much there is. I’d call that an illness rather than a symptom.

Of course AI is a totally new concept and has never had a market crash before.

Channel names would be very helpful here.

And yeah, his titles are certainly tending toward clickbait, but it’s also the case that things really are nuts lately. (And not just politically, stuff like the various Hubble constant measurements make for exciting times also)

If it were that small we would have detected the curvature already.

Last I heard I’m pretty sure they have ruled out any size of the whole universe less than 1000 times as big as the observable universe, and I think that might be radial size, so the minimum volume would be a billion times as large as what we can theoretically potentially see.

But the measurements are also consistent with 0 curvature, which would be the value for an infinitely large whole universe.

Those link to communities, not specific posts.

I really wish the Lemmy devs had come up with a portable post URL format. Maybe something like

https://*any-instance*/post/*number*@*source-instance*

Then the clients could handle it like the ! links for communities and also just rewrite links to be for the currently logged-in instance.

Boost either.

It’s a well taken picture of a barbaric subject. I’m not going to vote either way.

Very cool!

Similar to one of the neatest things I ever saw: a small drop of mercury under a microscope. What I saw was the room around me, like one of those round wall corner security mirrors.

I could imagine it being a scene in an action movie - the hero hides in a lab among the scientists, grabs a lab coat, and a little mercury, and sets up at a microscope. We see their view of the room when the villains sneak in and the hero, knowing exactly where they are, suddenly attacks or something.

Ah, sorry I hadn’t even considered that it would be different in other places (just times) - I’m in the US, and those flat ones were present here at least as late as the 1980s and likely 1990s.

Cable Internet is very common in the US, in fact the most common kind. (2nd is DSL) So the F connectors (didn’t know that name) are everywhere. Also still used for actual antenna connections.
I am not sure if I have ever seen a Belling-Lee, but RCA used to be extremely common here until HDMI took over that role. (In fact RCA is what is on the switch box above to connect to the ‘computer’)

Yes, it’s for an old game console or computer.

There were two common ways to connect to the TV, and this box supports both: Coaxial (still around of course) and that flat ribbon cable, which ends in two separate U shaped clips. The screws on the bottom are for the clips on the ribbon cable from the physical antenna likely mounted on the roof.

Ah, makes sense. Also I had failed to notice the phoronix link in my app.

Oh! I hadn’t even noticed the phoronix link. Thanks

So what does it do?

1. Perhaps Japan?
2. I feel like the US is getting really close to this honor, but I would still name a different one. Not sure which.
3. Germany being all anti-nuclear-powerplant without (in my opinion) good reason.

Heh, that would be neat. Maybe that’s what stegosaurus plates were: a MIMO array.

Sure. But RF can go through dense bush or a forest even better than audio if it’s high enough power - and without alerting any non-RF animals like audio would.

Or imagine animals with actual radar for finding prey. IR is good for that (I know snakes use it) but again radio could penetrate cover, and yet nothing uses it like that.

The main point though, is that RF exists despite non-use by life (excluding human technology of course). The same likely applies to dark matter and dark energy whatever they end up being.

That’s quite some hostility and unhelpfulness.

Anyway, after an overly difficult search (go enshitification) I did find this. So I have edited that part of my first post. The overall point remains though - life as we know it doesn’t always make use of Every possibility, so lack of use (on earth anyway) does not mean lack of existence.

Anyway, I was indeed wrong about two of my examples, so here’s two more to replace them, of very similar nature:

Nothing evolved to transmit or receive neutrinos or gravitational waves.
Mostly because doing so for neutrinos would require being the size of a large building for receiving, or containing a nuclear reactor (oh hey, there’s another thing life hasn’t done) for transmitting. For gravitational waves that would be small city sized for receiving, or being star sized with uneven mass at high speed for transmitting.

[citation needed]

I was very careful to phrase that with ‘selected for’ because of course things absorb radiation. That’s how bones are visible in X-ray radiology. But that doesn’t mean it is something they evolved specifically to do.

There are tons of phenomena or technologies that exist but aren’t used by life. The most famous is probably the wheel (with an axel, rolling a whole body doesn’t count, nor does cellular machinery).

As far as I know no living thing has selected for transmitting or receiving radio frequency radiation, nor X-rays or gamma rays. [Edit: eventually and with no useful guidance I managed to find This. Note how I linked it so others can learn about it. Still didn’t find anything for RF. End edit.] (I’m sure electric eels and such put out some RF, but only as a side effect. They aren’t using it for communication or sensing for example)
