Those are a lot of leaps to make about my motivations!

Something solid ahead

To clarify: I mean that, generally speaking, the presence of 'cloudy' water would presumably signify that the seafloor was close. In the open ocean, maybe a sea mount is surrounded by essentially a cloud of particles.

Edit: I think your reply made the thread reach maximum depth, so I'll end it here.. I should do more reading on the topic.

Wouldn't the cloudiness itself be a signal?

Presumably it's essentially clear of suspended particles, most of the time.

> Radar is useless underwater, light would also be useless for spotting anything in time to react at speed, and sonar isn’t routinely used because it compromises stealth.

Any people with knowledge in the field care to comment on whether it's feasible for a light (em?)-type, active, near-range detection system to work?

It seems to me the basic problem is:

- enough energy to get a signal at a range sufficient to move around any detected obstacles

- high enough dissipation in water to minimize range at which detection by external sensors is possible

I suppose it's a bit of a scotsman argument, but the turing test is to see whether an observer can correctly guess whether the interlocutor is _human_, so by definition the test would pass if the other correspondent was human.

To the point underneath, humans do not answer in as predictable a way as ChatGPT. Your answer, for example, I am confident does not come from ChatGPT.

Edit: if I've horribly mangled the Turing test definition, please let me know

This is what I got on ChatGPT today. I assume it used GPT4:

        Prompt            ChatGPT           Actual       Match
  397,356 * 930,547   369,685,207,932   369,758,433,732  FALSE
   36,330 *  26,951       979,458,630       979,129,830  FALSE
    8,681 *   9,330        80,911,430        80,993,730  FALSE
      278 *     903           250,734           251,034  FALSE
       82 *      77             6,314             6,314  TRUE

Edit: # of correct digits (counting from leftmost) only exceeds 3 on the smallest pair. It drops to two, as well, on the 3x3 set.

The problem seems to be with defining good tests for intelligence. FWIW, because GPT4 answers have a detectable pattern, they should presumably fail the Turing test.

At some level, intelligence requires logic, rationality, and conceptualization, all of which are topics which have evaded clear definition despite millennia of philosophy directly addressing the issues.

Since LLMs can't do arithmetic, one has to think there's more going on, at least in the arithmetic part of the brain, than is going on in LLMs.

And a roommate of Richard Stallman at one point, AFAIR.

  the easiest way to mismanage a technology is to misunderstand it

Indeed.

His idea of attaching provenance to source of information used in models is a good one, and one that already has rumblings of legal weight behind it (see the various articles about copyright claims in response to GPT/Copilot).

I worry a bit that his argument is too centred on digital information creation. Though I suppose that's the novelty of the most recent pieces of technology called AI - they affect information workers, people who already use a computer interface for some large percentage of their work. Still, the topic of /physical work/ : fieldwork, factorywork, servicework, seems one or more steps removed from LLMs. The management of that work may be affected, but the work itself has already (it seems to me) gone through its first computer-revolution shock.

Edit: I'll add that the whole article has a 90s-Wired feel to it, which is refreshing to see. There's been something of a slowdown in tech-revolutions for the past decade, and it's not original to say that we may be at the start of a new one.

From the given link:

  As of April 2023, the average rent for a 1-bedroom apartment in Cleveland, OH is $1,136. This is a 7% decrease compared to the previous year.

Luckily, this[1] is also reading zero at the moment.

Very cool. Reminds me of the retroreflectors on GLONASS.

They've got 0.3m on World View 3, more than enough for what was shown in the gif

Edit: you're probably right, actually.. the silver square on the lower section of landsat 8 is ~1.5m high (guessing from the image on wikipedia), so there should only be ~5-6 pixels for it, but there are clearly more.

The distance to the earth might have been coincidentally the same as the distance to the other satellite. LEO isn't that far up, the one that took the photo was only ~600km AGL.

I'd just like to throw in a plug for what I think is the best-looking satellite:

GOCE: https://en.wikipedia.org/wiki/Gravity_Field_and_Steady-State...

It's a gravity survey satellite. They get better measurements if they fly closer to the earth, so there's a motivation to lower the orbit. GOCE flies so low that it needs to take aerodynamics into account, so it is sleek, like an aircraft.*

* It is, of course, actually an aircraft, like all satellites, to some degree, at least in the layman's definition of the word.

I always feel a little dirty when I click on twitter links these days.

If you had that you could (and I think this is GGP's point) have settings in the browser similar to phone privacy settings: allow cookies for (login || place || shopping cart || etc)

'electricite du magnetisme' would be a nice quadruple-entendre in French

1) electricity of magnetism => electrical side of the electromagnetic force

leads to

2) electricity from magnetism => generating electricity from a magnetic force

leads to

3) edm => electronic dance music

leads to

4) excitement from attraction => the feeling of excitement ('electric' metaphor for excitement) from meeting someone you're attracted to ('magnetic' metaphor for attraction between two people)

The fact that context matters so much makes it hard to avoid concluding that such relationships are not friendships in any sense of the word, they're just pleasantries to make the other parts of the context - the reason why you're in whatever situation - go more smoothly. Agreeableness. More agreeable with some people than others, sure, but not friends.

It's useful as an excuse for the OS to be continuously connected to the internet, which elides nicely into connecting to the internet for search results when you type something in the searchbox.

And you can't argue that it's /useless/. It's more information, and, ceteris paribus, more information is better.

Hot take, but: the same issue is present in math, with the aggressive deprioritization of rote learning of arithmetic. People need a foundation upon which to build higher concepts; knowing your times tables is necessary to grasp division algorithms.

The emphasis (in reading, and math) on the wider concepts rather than the boring learning is a problem.

I think you're sort of half right

I suppose there would be a rough conversion between that value and photon count (at some wavelength range). I just imagine the error bars to be very wide.

If there's a way to get an integer value on the number of photons per cell in a camera sensor, let me know

Purely as a matter of esoteric interest, does anyone know of any affordable photon counting devices?

The impact the time cost has on careers is significant. From what I've heard through science media, it's not uncommon for planetary scientists to spend half or an entire career on a single mission to the outer planets.
