Since you're here… This looks really cool. I installed, but running the demo produced no sound (but a pause). Any thoughts? I did seemingly install the dev branch of SoundPipe first. Please feel free to redirect me to a more appropriate support channel if available.

I got this: Poλλλote.

There’s help available, if not for you, for your children: https://books.google.com/books?id=R6E0AAAAMAAJ&pg=PA74&lpg=P...

Duly noted.

Maybe it is a circular list.

How dangerous is this app? I mean how much time does it give me? Is the danger that my document will be lost, or that in attempting not to let that happen I will write too much. I will write the wrong thing. I will go down paths which are meant not to be followed, ordinarily edited out of existence. This is the danger, I suspect. But the other is also. It is a double danger. This double danger models a double danger in other areas. It is perhaps a fundamental mode of danger. Dangerness. The fear of a thing which both prevents or enables, complementarily. How does that work? What are examples? Can we name a time the fear has positively (we posit) prevented manifestation? Certainly. In general, it is socially unacceptable to analyze or look too deeply past the constructs which supposedly shield prying eyes from the conclusions which would be evident if the components were scrutinized. China Miéville explores this exquisitely in The City and The City. There citizens of two nearly colocated cities 'unsee' the other by law. Likewise, we ordinarily must unsee what is meant to be unseen. The danger then is that our unseeing be threatened by the possiblity that we lose sight altogether. Backed into a corner and forced to confront complete unsight, we restrain the restrainer. We disassemble the governor so we do not accidentally edit ourselves out of existence. Through abolition of constraint we cross over into conceptual indecency.

How about not using 'pick a random number from 1-10' as the source of entropy? For example, have everyone (from a group of some size) select a natural language sentence of 5 words or more, sum the ASCII values of the upcased alphabetical characters of everyone's sentences, and take the last digit (then add one).

I think you mean 'intersection'.

That’s it, yes. Thank you.

Do you know if this can be configured to work with Sage? If so, could you link to an example or instructions?

I agree entirely with your sentiment. Still, I'm not sure corporate personhood means we should judge corporate action as we would human action. It's still not possible to expect corporations to never mistakes, but I wouldn't excuse it on the basis of their humanity.

On the bright side, this set you up perfectly for Emerson's 'Self-Reliance'.

All I have to say is that I misread this headline and experienced both disappointment and relief when I clicked through and read about a 'buttonhole' camera.

Yesterday evening, my daughter noticed an iPad had been removed from its case and held up the empty one asking what gives? My immediate response, "What you're looking at is the THINNEST, LIGHTEST, iPad we've ever produced. It's 127% faster than the case alone. And now for something we know you're going to love. In the past you've enjoyed lunch, and you've told us about how much you liked late lunch. Tonight we have something really special for you, and I can't wait to tell you about it. Introducing dinner."

I have a very relevant anecdote:

My grandfather was an open-heart surgeon. In the days following surgery, he would always insist that his patients get up and take a short walk. They would not want to, but he insisted that this was an important and valuable part of recovery (in several dimension) and that they needed to push past resistance and force themselves to do it.

Later in life, he underwent a surgery requiring general anesthesia and found himself in the same position. He said, "If I had known it was like that, I would not have made them do it."

So I think the surgeon's personal experience of the situation is -- in fact -- highly relevant in practice, even if not in theory.

As I recall, the most interesting feature of these networks is that they do better when learning geometric features in the presence of noise. Without the added geometric structure baked into the network, the real neural nets overfit and 'learn the noise' to a much greater extent.

Here's the thing: the way HRV is measured reliably when used as a metric is with 'paced breathing'. You synchronize your inhalations and exhalations to a displayed pace (in for X seconds, out for X seconds, or whatever).

The primary source of variability under those conditions seems to be that HR increases when inhaling and decreases when exhaling. Seen in that light, it makes more sense.

Essentially, what HRV may measure is ability to actively and acutely lower HR (which is most naturally performed during exhalation). This is not so unlike how some exercise equipment will provide a fitness measure based on heart-rate recovery: how long does it take you to return to some percentage of your resting heart rate after having exercised?

At this point, I'll make an analogy, which is meant only to be that. If you have a high income, you can afford to spend a lot of money on a day-to-day-basis. Depending on how you set things up, you might see a wild flux in bank balance, and that's just fine -- because you can afford it.

Likewise, performance athletes experience highly-elevated heart rates regularly. Indeed, it's that stress which leads to fitness adaptations. Just as you need to spend money to make money, you need to stimulate the heart in order to strengthen it. High HRV (as far as I can tell), may largely correspond with the naturally-adapted ability to rapidly return to the calm, low-HR state characteristic of the well-trained athlete.

When you live check-to-check, you have to budget very carefully and avoid variability in spending. You can't afford to venture, and you don't gain. When you know huge cash infusions are around every corner, you don't worry about spending.

Likewise, the fit heart doesn't need to damp and suppress stimulus. Elevated heart rate is good (think about the positive moments in life which can cause this), as long as it doesn't lead to chronic stress but instead evaporates in the space of a breath or two.

As far as I know, the best apps for HRV are Marco Altini's: http://www.marcoaltini.com/apps.html

That was useful. If and when I need pure C++, or want a fast path to 'additional things', it sounds like versor is the way to go.

There is a lot to sort through in coming up to speed with this paradigm, and each new source helps build the practical picture. Thank you for contributing to that.
