Suspended animation is becoming a life-saving medical procedure - <AUTHOR> http://prime.nautil.us/issue/22/slow/how-to-turn-your-dog-off

<comment><USER2> Looks like an expansion of this work: [http://www.popsci.com/technology/article/2009-12/save- soldie...](http://www.popsci.com/technology/article/2009-12/save-soldiers- battlefield-darpa-wants-suspend-animation)

Also, there's this trial going on to cool the body to increase the time surgeons have: [http://news.nationalgeographic.com/news/2014/04/140402-suspe...](http://news.nationalgeographic.com/news/2014/04/140402-suspended- animation-gunshot-victims-science-death/)

I think the first time I recall some interesting work in suspended animation was in ~2006. It's impressive to see how far the techniques have come since then.

This sort of thing is by now routine, and also is used for some brain surgeries.

It's been difficult for me to understand whats new enough about this that it has been making the rounds in the news. Some of the new stories a few months ago seem sparked by a recent clinical trial, which (I think) was sorta novel in that it used these techniques in emergent situations.

<comment><USER4> It seems likely the Nautilus article is related to the mentioned paper, which was published in November:

[http://journals.plos.org/plosone/article?id=10.1371/journal....](http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0112458)

<comment><USER3> This is impressive. Any know if this is supposed to be just for hearts, or could be used for strokes too?

<comment><USER5> It should be useful for anything doctors can fix if they have the time.

Here's an article from 2014 in which they discuss a trial testing hypothermia for trauma patients who've bled out:

</comment><comment><USER8> The article doesn't mention the impact of loss of oxygen to the brain. I would have to assume, that if this is moving to human trials, that there is evidence that this reduces or eliminates the effect of oxygen deprivation on the brain?

<comment><USER9> I would suspect that, since the whole method of action seems to be to reduce the cells' metabolic need for oxygen, there wouldn't be damaged from "deprivation" because the cells would still be getting all the oxygen they required.

</comment></comment><comment><USER10> Perhaps somewhat related, in that slowing metabolism saves tissue:

Show HN: Python on iOS Native Apps - <AUTHOR> https://github.com/joaoventura/pybridge-ios <comment><AUTHOR> This project is a base for which to add a python interpreter to a swift iOS project. It allows us to call python functions and get the resulting string, and then use the result in swift code (to update native widgets, etc.)

As I'm a beginner in swift and iOS, I've documented all the process at [https://github.com/joaoventura/pybridge- ios/blob/master/docs...](https://github.com/joaoventura/pybridge- ios/blob/master/docs/references.md).

I hope this allows me to share all the Python code in my Android app ([https://play.google.com/store/apps/details?id=com.flatangle....](https://play.google.com/store/apps/details?id=com.flatangle.charts)), which uses the same technique but for android ([https://github.com/joaoventura/pybridge](https://github.com/joaoventura/pybridge))

<comment><USER2> Are you okay with having your app's binaries string dumped by unknown parties where upon they find the underlying Python source code? Some basic encryption (or tokenization) would be better, since few would expect to go looking for it.

<comment><AUTHOR> A simple strategy is to include only the pyc or pyo files inside a zip file, and it will continue to work as well..

</comment></comment></comment><comment><USER3> Does anyone know the latest on the Swift-Python bridge from the TensorFlow team[0]? Is this still in development or usable for iOS apps?

<comment><USER4> I believe that you need the S4TF _fork_ of the Swift compiler. It might be doable to swap it into Xcode as part of an alternate toolchain, but it's not likely to be easy.

<comment><USER5> Note that Apple will not let you put an application built with an alternative toolchain on the App Store.

</comment></comment></comment><comment><USER6> Similar (?) project where you can write Python code and create apps for iOS, and Android (and others) [https://beeware.org/](https://beeware.org/)

The talks from the author, Russell Keith-Magee, are very interesting, I learned a lot about how apps work.

<comment><AUTHOR> As the sibling commenter said, that project and kivy are geared to write android and ios apps entirely in Python.

My approach is different. I have most of the business logic in Python (I share lots of code between a web app and an Android app I have) and write the UI logic in the platform's native language. This means the apps are always using native UIs and use the platform toolchains, and I can use all tools available natively on the platform.

</comment></comment><comment><USER7> Is this even allowed by Apple guidelines? Isn't it the same rule that banned Flash?

</comment><comment><USER8> Do you know how much using python and the framework adds to the binary size?

<comment><USER9> I am not that worried about the binary size, but please see this discussion regarding loading times earlier today:

<comment><AUTHOR> The answer to that post is mine, and i confirm that there's some delay on start but on a moto g 2014 that i have it is ~3 seconds which is not much. By comparison, Outlook takes more than 10 seconds to start on my iphone 5s..

<comment><USER10> That's pretty crazy re outlook. Takes about half a second on my 11. Clearly mine is newer, but over an order of magnitude is a lot.

<comment><AUTHOR> Tested right now: 8 seconds of a white screen, then the blue logo appears for 2 seconds, and finally, at second 10, mails start to appear..

That is why I always test my apps on older hardware.. That, and because i only have old devices.. :)

<comment><USER10> I noticed that if I quit the app via the usual mechanism, it takes less than a second to load. However if I fully power cycle the device it's closer to 5 seconds.</comment></comment></comment></comment></comment></comment>


Duolingo, learn a new language while translating the web - <AUTHOR> http://www.duolingo.com

<comment><USER2> I tried this out because I know a little French and would like to know more.

I was first put off becuase when "Je suis de Anchorage" (which I'm pretty sure is not idiomatic anyway) was expected, "Je suis d'Anchorage" (which is correct within the scope of the already unidiomatic expectations) was not allowed. Granted, French is still in beta.

Then the audio portions produced... no sound. It's a bold move for a web site to depend on audio. I recommend making sure it works first.

'You will be sexually harassed': just one of the perils of working for tips - <AUTHOR> https://www.theguardian.com/us-news/2017/sep/28/you-will-be-sexually-harassed-just-one-of-the-perils-of-working-for-213-an-hour <comment><USER2> Sounds like most are single moms too. In more socialistic countries we just give them other peoples money.

<comment><USER3> No, they're given some of their society's money, since they're a member of that society. That money doesn't belong to any individual, it belongs to society as a whole.

<comment><USER2> If you take money from individual A put it into a common pot and then give it to individual B then individual B is effectively getting individual A's money.

<comment><USER3> _> If you take money from individual A _

Like I take money from the company I work for, in payment for my services...

 _> put it into a common pot _

I put it in my bank account...

 _> and then give it to individual B _

I buy something from Amazon, say...

 _> then individual B is effectively getting individual A's money._

Then Amazon is getting my companies money? Erm, no. Once it's been paid to me, it's _my_ money. That's how payment works. When you pay for a society's services, that money is no longer yours. If you're a member of that society you still get a say in how it's spent (not always the case: you might be from another society and just paying for market access) but it's not your money any more.

<comment><USER2> The company has a choice of not employing you though and it tells you exactly what work to do. Now if you force the company to pay, then yes your example confirms my statement.

<comment><USER3> You have a choice not to use that society's services.

If I did work for the company and then they refused to pay me, then yes, I would force them to pay. I would use the law to force them to pay.
