Comment A different take on why they're well-suited: (Score 4, Interesting) 109

Folks on the autism spectrum may well be better at testing than folks who aren't.

But they may also find the repetitive or tedious parts of testing less painful than folks who aren't.

I know software testing is a big field, encompassing a wide range of activities, and that every job has its monotonous and unrewarding parts. But, from what I've seen -- working with SW development, working with testers, working with kids (and maybe some adults) on the spectrum -- the things that "most of us" find monotonous and tedious are frequently rewarding and reassuring for them.

To the extent that this is true, it's a terrific win/win/win scenario. Companies get people particularly well-suited for the job. People well-suited for the job get work that they enjoy. People not well-suited for the job don't have to stick with drudgery because "nobody likes to do it but somebody has to".

Comment In this house we obey the laws of thermodynamics! (Score 2) 145

Passively cooling an object below ambient temperature seems... counterintuitive. I think I understand what's going on here, but I'd like to see some more thorough discussion. Particularly, I'd like to know how you can find any passband in which an object at ambient temperature radiates more heat than it takes in from direct solar exposure, except the bands blocked by the atmosphere.

Comment It was Perkin-Elmer's mistake. (Score 1) 203

That was NASA's mistake. The mirror was made to spec, but NASA didn't work out how it would deform in orbit/a microgravity environment.

That's an interesting claim, but entirely fictional, as far as I can tell. I followed the story closely at the time, and in the end, every report I saw put the blame on a defective Perkin-Elmer null corrector assembly (reserving some blame for NASA's inadequate oversight of their development and testing processes).

Why are you trying to rewrite history?

...but I can't help suspecting the forced rewiring of my brain hasn't helped my general learning capacity.

I expected you to say that it HAS helped your general learning capacity, but you're implying that it hasn't. Could you please clarify or reinforce your point?

Comment Re:Listening through noise or interference (Score 1) 62

Well if you convolve a signal with a 1Hz sinc wave the signal is "replicated and redundantly presented" but provably most of the information in the original signal is now lost. Interference correlated with the original sound is a convolution. It destroys information, it has to. It makes the problem harder, that's why our brains can't handle it, although our brains have context-based processing which allows us to recover a lot more than a system without that.

Perhaps. As you can surely tell, this is well outside my expertise.

Also, our brains are not hard-wired.

Forgive my imprecise wording. Brain wiring is malleable, but there's a lot of built-in structure, especially around perception and language processing.

I'm not familiar with the IBM demo you mention, but the key there is the controlled vocabulary. It was probably also trained on the speaker's voice. Those are huge constraints.

I'm remembering that it was controlled-vocabulary, but speaker-independent. I think it was trained on spoken digits -- a very small vocabulary. It's been a long time, and I may be misremembering even the most basic details. Still, it was impressive to hear it picking out numbers where all I could hear was noise.

Comment Listening through noise or interference (Score 1) 62

I remember a demo out of IBM, I believe, for recognizing controlled vocabulary in high-noise environments. It handily OUT-performed humans -- listening to the test audio, you couldn't really be sure there was a human voice at all, but the software detected and interpreted the speech with high accuracy.

This demo would have been circa 2000. I can't help imagining that there's been more progress since then.

The proposed task, where the interference is correlated with the original sound, seems like fertile ground for superhuman performance again. The original signal gets replicated and redundantly presented. Our brains are hard-wired to be confused by that, but it seems like a well-designed speech-recognition system could take advantage of it.

Um, but I think OP was trying to build a case to justify sending people to Mars or something. Because we *need* to explore or some such romantic nonsense.

It would appear that this says a lot more about your thought processes than about anything OP actually wrote.

Think about how long it takes a meteor to descend through the atmosphere and decelerate to terminal velocity. It's a few seconds.

Now, think about how quickly metal or rock conducts heat, and how quickly heat dissipates into moving air or solid ground.

Nearly all the object's kinetic energy goes into compression heating of the atmosphere. Of what's left, nearly all goes into ablating the object's surface. When the object hits, its interior is still cold.

Or, you would need 10 000 comets mashed together into the same volume to have the surface gravity of earth.

...and they wouldn't stay that squished for very long. The explosive rebound of the comet's surface would vastly exceed its escape velocity. Or, to put it more succinctly, BOOM. Unless, of course, you can wrap it in a stasis field, or stabilize it with some other layer of handwavium...

Comment It's not how YOUR air conditioning works... (Score 1) 34

Refrigeration is only one of numerous ways to do air conditioning. The important thing is modifying the air's properties (temperature and/or humidity) to better suit a target application.

In this case, the dinosaur had a sophisticated heat exchanger, one key component of air conditioning. But the "air conditioning" (warming the air) isn't the function they're emphasizing -- they're emphasizing the "chiller" function, where that air controllably cooled blood circulating to the brain.
