> There is no lie or misleading information about rust in the title so it’s clearly not clickbait.

That’s not what clickbait means at all.

[senordevnyc → echoangle]

That’s exactly what clickbait means:

Clickbait (also known as link bait or linkbait) is a text or a thumbnail link that is designed to attract attention and to entice users to follow ("click") that link and view, read, stream or listen to the linked piece of online content, being typically deceptive, sensationalized, or otherwise misleading.

Where would a company ever get their market cap in cash? If they had that, wouldn’t they by definition have a higher market cap, since the value of the company is cash + the rest of the company?

> since the value of the company is cash + the rest of the company?

Failing companies sometimes trade below cash value. OP's basically creating a rule by which only failing companies are allowed to go public. (Or those who have paid a king's ransom to a megabank.)

As someone who has not used Sympy: Why does it need a successor?

[breezybottom → echoangle]

Development is pretty much dead other than some bug fixes. It's been long overdue for a major rewrite.

I think google is an imperative verb here. You're supposed to google (as in search for) Linears Videos.

Isn’t the revenue modifier a result and not the cause?

Would you really expect a company to increase proportionally in value when they increase their revenue?

That’s probably what’s meant by statistically impossible.

On: Astronauts told to return to ISS after sheltering over air leak repairs

[echoangle]

Some problems i can see with that:

It might be hard to access the actual pressure hull from the inside (there's probably insulation and padding on top)

If you use paint, you somehow have to get rid of the solvent in it when it dries, which might be a problem when painting a whole module

[Lalabadie → echoangle]

Air filtration is one of the hardest things do deal with in space.

I don't know what solvents would do, but I remember that astronauts' bone density loss in space means there are challenges around managing the significant amount of calcium captured by the air scrubbers in the ISS.

[kakacik → Lalabadie]

Do they literally sweat their bones away? I can imagine how it would work on molecular level via sweat / breathing, but I would expect >99% to be simply pissed and shat away.

[Lalabadie → Lalabadie]

Edit: My bad, with calcium it's the liquid filters that deal with it, not the air scrubbers.

Quoting an ISS astronaut: Today's coffee is tomorrow's coffee.

[PaulHoule → Lalabadie]

Wouldn't the calcium go out in your urine?

[schiffern → PaulHoule]

Yes. It was the urine processor that had problems with excess calcium, not the air scrubber.

Appreciate the correction!

On: Watching a Z80 from an RP2350

[echoangle]

Why wouldn't you just emulate a Z80 on the RP2350 at that point?

[codebje → echoangle]

Same reason you wouldn't just emulate a Z80 on a desktop. People don't build retros because they're practical.

[jensgk → echoangle]

On: Sagrada Família Lego set

[echoangle]

The shape doesn't matter for the scaling as long as it is a 3-dimensional object that is scaled in all directions.

And I think for the actual value you get, scaling by volume would actually be more accurate.

[nikhilisvalid → echoangle]

The original took 144 years to build, and this model is anywhere between 153 to 278 times smaller. If one were to scale by volume, the build time would take at most 22 minutes, and at least 3.

I think scaling linearly works better here

[echoangle → nikhilisvalid]

Well that’s because you’re building alone and there were multiple people at once doing the real thing, and it’s a different construction method.

That only determines a constant factor though, the scaling of build time for a given method should roughly follow volume.

Would you say that building a Lego version that’s twice as high takes double the time?

On: Artificial intelligence is not conscious – Ted Chiang

[echoangle]

If we want to be really pedantic, a computer does not necessarily need to be digital. You could build a consciousness-coprocessor with analog circuitry that brings in what you say could be needed.

But honestly I doubt that there is a real requirement for that, surely you could just increase the resolution you're running the simulation at until the difference decreases sufficiently. Imagine using 256 bit floats for example.

[nomel → echoangle]

IBM has made a few analog chips like this [1]. If I remember correctly, one was even pulse time based, like neurons.
