> How many hidden industries like the pallets one are out there...

Within one standard deviation of the mean, all of them.

Most hackers trying to 'disrupt' things naturally only work on what they know. So a lot of solutions are developed for industries everyone knows about: restaurants, travel, education, etc.

But most of the world's industries are not conducting business out in the open. They are operating inside factories, warehouses, labs, shipyards, trainyards, depots, private buildings, on the road, and in the field.

This is why a little niche knowledge is so powerful. Many industries only see innovation from people within the industry. But they usually have the same technical background as everyone else there, and the same blind spots. The hacker who has (or can get) enough domain knowledge to apply hardware and software in the right places is basically a Wizard.
> exactly what your body needs and nothing else?

Soylent's main ingredient is maltodextrin which is certainly not essential to any diet.
Right? Except it's not a $500 paperweight. It's a $4,500 paperweight with an additional $500 a year overhead.

Depending on how effective Project Tango is, this technology might be short lived. Maybe there's some manual labor that has to happen on their end before your files are ready? Otherwise I just don't understand the cost. Storage and bandwidth couldn't possibly cost $50/mo.

Sometimes I really do lament the fact that everyone decided that an ongoing subscription model is the way to go for everything.
> What distinguishes one from the other?

The drastically different way you pronounce a word, or even the choice of words.
Well for example for the sentence "I feel very cold".
Mandarin: wo jue de heng leng
Hokkien: wa chi tio jin na leng
Teochew: wa chi tio jin nga ngang
etc...

> Then, before the development of kana, was Japanese also a chinese dialect? Korean before hangeul?
> If I wrote the english sentence "how old are you?" as 多老是你？, would that make english a dialect of Chinese? If > I wrote 你多大？ as "ni duo da?", would mandarin stop being a chinese dialect?
> If you imagine two illiterate people, one of whom speaks mandarin and the other cantonese, do neither know any language at all, due to being illiterate?

I do understand what you're saying, and I do agree with you regarding the examples above. But then how would you explain the relationship between Chinese, Mandarin, Hokkien, Hakka, Teochew, etc in terms of language vs. dialect?

Awesome. I'd really love to see one of these that's good enough to actually use at scale at a large party. This one looks closer than a lot of the others that I've seen. Perhaps higher quality peristaltic pumps (higher flow rate, less noise) in combination with more ingredient chambers would push it over the edge.

Can anyone here better explain the hand-wavy stuff about re-connecting the spinal cord? I (incorrectly or not) think of the spinal cord as bunch of wires, presumably that have to be connected to the correct counterpart individually. In the article they talk about reconnecting the spinal column in ~2 minutes, which seems to rule that out.

That's a little cynical. I like to think we can predict big historical social events (regime changes, major protests, climate change?) based on Twitter's data.

Nice job man.
"Boring"? While they aren't particularly pleasant those boring products come in a variety of flavours and styles (soup; juice styles; shakes).

Everytime Soylent comes up and someone mentions the existing product Soylent supporters claim that Soylent is a peoduct you can live on. (Ignoring the fact that you can live on those other products) you've just removed the only differentiator.
Yeah, keepass2 works w/ mono. I have it installed on an xubuntu system. There's an official package (in universe).

keechallenge is also supposed to work w/ mono. That said, at least on my machine the fonts in keepass2 are rendered too small, making the application very difficult to use. I spent about an hour trying to figure out how to fix them and could not, so I have not tried setting up keechallenge there.

I think you're way off with your point that we can't (or shouldn't) shun these based on the principle that monitoring is wrong. There is nothing to gain from having kids expect to be monitored and being ok with being monitored.

Educational systems shouldn't rely on the students to be working hard or work right; they should clearly be relying on the teachers and the school to set up a good environment for the students to _want to learn_. Monitoring students will give nothing. Maybe monitoring the teachers would, though, if that's the route you want to take. Something tells me they wouldn't like it that much.

Why did you bother to learn Python 2?

Scientific code typically translates cleanly using 2to3, even. You can get up to speed with all those "terribly complex" changes in Python 3 in about five minutes. Scientific code in particular typically has no advanced unicode handling and no custom CPython extensions, so switching is trivial.

I totally agree with you: Py 2 vs 3 is of very little significance to us scientists. Which is why I use Py3. There's nothing to gain by sticking with Python 2, and almost no effort at all to go Python 3.
I think you missed my point. I presented a hypothetical situation where in an alternative reality Python 3 happened to instead integrate something like PyPy in it (or say have any other mind blowing features of that caliber).

> So, you'd want people to switch to PyPy, not Python 3.

I personally would want Python to be used more because I like it. But I see how a community has been divided over what I see is an un-necessary backward incompatible change to the language.

To put it another way. I would rather not have backwards compatibility issues and just keep having 2.8, 2.9, 2.10, if all we got was what we got with 3.x
Carbohydrates are, however. From the Soylent 1.0 ingredients list:

> Maltodextrin (165g) - As the primary source of energy for the body, carbohydrates are the largest component of Soylent by mass. The starch in Oat Flour makes up the bulk of this nutrient and the rest is provided by Maltodextrin.

This is relevant to an argument two friends were having last night. Their opposing viewpoints:

a) bitcoin is a great investment
b) bitcoin is worthless

You're both wrong!

Even the possibility that darkcoin supplants bitcoin as the "premiere" cryptocurrency means that putting significant money in bitcoin is extremely risky. But as more alt coins gain traction, it adds more evidence that cryptocurrencies are here to stay, whoever ends up being the the winner(s).
This may be the coolest thing i've ever read. It also reminds me of an old Russian science fiction book "Professor Dowell's Head" a little

"More than 25,000 phytonutrients are found in plant foods. WebMD takes a look at these six important phytonutrients -- and their potential health effects: Carotenoids, Ellagic acid, Flavonoids, Resveratrolm Glucosinolates, Phytoestrogens"

Find them in Soylent? It's cute that you put nonessential nutrients in quotes though. It's like this foreign term that only I use.
I've been following darkcoin since the day after it was released, have talked to Evan (creator), and I really do not agree.

[0] is only temporarily true as pointed out already.
[1] doesn't support what you said, the about us NOT saying they have experience with X, Y and Z does not mean the same thing as it saying they do not have experience with X, Y, and Z.
[2] I've always disliked that, however price changes are what get people excited, I would potentially say even more so than innovative features.

So I really don't think scamcoin is the right term, however I personally would not be investing at the current price. I sold all my darkcoins a while ago for a very nice profit and cannot see the price rising a whole lot higher (in the short to mid term) than it currently is, unless a large DNM starts accepting it or similar. Then again I also said I can't see the price rising a whole lot higher when it was at .01 DRK/BTC, so what do I know?

Very cool! From a health perspective, has anyone looked into whether these homemade machines for food/drink are safe for consumption?

They explained that a few compounds including polyethylene glycol can help glue the nerves together and function (transmit electrical impulses), as they claim, at 10% efficiency. They then state that better compounds exist and that efficiency can also be improved with some other chemicals.

At least so I read it
Darkcoin has all of the priors of just another altcoin speculative bubble (some of which are outright scams, some of which just lose faith and attention).

What is different is that it hints at a future, near, profound technological shift. If Darkcoin doesn't successfully implement an anonymous sending functionality, another ecurrency or bitcoin itself will.

The real reason why GE is turning to "industrial internet" is because European firms have started a similar initiative previously, called "Industry 4.0":

Of course, GE will try to establish its own standards, which are incompatible to those of their competitors (e.g. Siemens).
In theory, nerve connection is quite easy. Put two nerves of the same type right up next to each other and they will fuse and form a continuous signal transduction pathway. However, the success rate for this is somewhere on the order of 80%. Assuming there are ~100 connections to be made, 0.80^100 isn't very enticing. Perhaps using the compounds he talks about can increase the success rate, but this is still on fairly shaky grounds.
Yeah I caught that. I'm wondering more about the alignment problem. You wouldn't, for example, just glue a severed bundle of fiber optics back together without reconnecting each strand individually.

That was a good one.

On a more serious tone, there is one area of research that Twitter data is very valuable for: how information and disinformation is created and spread during major news events: wars, catastrophes, uprisings, school shootings etc.

My gut feeling is that today a lot of quality journalism happens outside of the traditional journalistic organisations. The downside is that also a lot of wild speculation and rumours are spread, but it would be valuable to see how good this modern "crowd" journalism is. A skilled research group can use Twitter data and Internet Archive to track down the original sources of information pretty well.

The liquid should not touch anything outside of the tubing or tubing interconnects, so it shouldn't matter so much if the parts don't meet FDA requirements.
Arguably, this isn't a "head/spine transplant", it's a "body transplant". Whichever part the brain is in is the important part.
>Carbohydrates are, however.

Carbohydrates are in no way essential to a diet if replaced with proper amounts of fat and protein. http://eatingacademy.com/
One of the large benefits of peristaltic pumps is that the only thing that the liquid touches is the tube.
Yeah, this is way better. The tennis one is too focused, and the market is too small.

What if it turns out that people can greatly extend their lifespans, or even live forever, by undergoing successive head transplants -- but every time one person gets transplanted, someone else has to die to provide the body?

What if we're headed for a world where the rich and powerful hire body snatchers to kidnap people off the street to provide bodies whenever they need a transplant? What if there are loopholes in the criminal justice system or covert government agencies that will allow people with the right connections to get access to an organized supply of helpless victims?
Can anyone find a primary source?
Why not? Brains adapt very well. Monkeys given a brain implanted electrodes that control a mechanical arm learned to use it in days.

If Python needs reviving then Python 3 is the reason.

But I suspect what needs reviving is Python 3. If functioning unicode support isn't getting people to switch, it's got an uphill battle on its hands.
I bet the thinking was something along the lines of "kitty litter is an inert absorptive material", and nobody really thought much about the differences between types of kitty litter, and whether or not they were truly inert.
Scary, but science marches on no matter the possible misuses of it. Outlaw it here and China'll do it. Outlaw it there and Russia will. Outlaw it there and somebody will buy an aircraft carrier and pay to do this in international waters. It will happen eventually. Might as well enable it and provide ethical guidance as opposed to banning it and letting someone else do it covertly and with no oversight or considerations of ethical ramifications.

To address some of the comments being presented here, neural nets despite being harder to train can be debugged visually.

A few tips for those of you who use neural nets:

Debug the weights with histograms. Track the gradient and make sure the magnitude is not too large and its normally distributed.

Keep track of your gradient changes when using either gradient descent or conjugate gradient.

Plot your filters, visualize what each neuron is learning.

Watch the rate of change of your cost function. If it seems like its changing too fast and stops early lower your learning rate.

Plot your activations: if they start out grey you're fine. If you start all black, you need to retune some of your parameters.

Lastly, understand the algorithm you're using. Convolutional nets are different from recursive neural tensor are different denoising autoencoders are different from RBMS/DBNs.

Pay attention to your cost function, reconstruction entropy is used differently from negative log likelihood is used differently for different objectives.

If you are trying to do feature learning, you are using RBMs, Denoising AutoEncoders and you will use reconstruction entropy. This is what you use for feature detectors. You may end up using negative log likelihood if you are dealing with continuous data.

For RBMs, pay attention to the different kinds of units[1]. Hinton recommends Gaussian visible with recitifed linear for continuous data, binary binary otherwise.

For denoising autoencoders, watch your corruption level. A higher one helps generalize better, especially with less data.

For time series or sequential data, you can use a recurrent net,moving window with DBNs, or recursive neural tensor

Other knobs:

If your deep learning framework doesn't have adagrad find one that does.

Dropout: crucial. Dropout is used in combination with mini batch learning to handle learning different "poses" of images as well as generalizing feature learning. This can be used in combination with sampling with replacement to minimize sampling error.

Regularization: L2 is typically used. Hinton once said: you want a neural net that always overfits but is regularized (youtube video...don't remember link right now).

Would love to answer questions! Source: I work on/teach this stuff. Still working my way up there, but it seems to be going well so far.[2][3]

Lastly, tweak one knob at a time. Neural nets have a lot going on. You don't want a situation where you A/B tested 10 different parameters at once and you don't know which one worked or why.

Because there is already enough food for the world, that food is just poorly distributed.

But concentrating on just the specialist end of disaster nutrition: World Food Programme et al already have products that are vastly cheaper than Soylent.

20% of the world population live on less than $1.25 per day. About one billion people lack access to clean drinking water (the primary ingredient in Soylent).

Here's what the world food programme does: https://www.wfp.org/nutrition/how-wfp-fights-malnutrition

Here's a list of special nutritional products: https://www.wfp.org/nutrition/special-nutritional-products

Here is the factsheet about existing WFP products (note price and shelf life) : http://documents.wfp.org/stellent/groups/public/documents/co...

Soylent is far far too expensive for this role. It requires clean water. Rob making the claim that Soylent could help world hunger is yet another sensationalist sleazy claim made in ignorance of existing market.

Be careful about groupthink. As you get older, you get less and less inclined to just agree with something because everyone else thinks it. When you're young, its almost impossible not to be a member of the pack - but as you get older, you realize its not enough to be the alpha dog. You've gotta get the whole mob through the job. That's not always a management role, you know.

A majority of the aged 40+ developers that I know are still writing code. They're very productive, very certain, and have the experience that a lot of younger guys don't - especially with the social aspect of our industry. Its not enough to be 'the rightest guy in the room'. Its also not enough to be the 'most active developer with all the energy' in the room. What matters is that everyone in the room is right, because of the work being done together, and that the groups' motivation as a whole is more important than any single developer. Of course, if all you've ever done is work on a small (2 or 3) man group, its quite possible the idea of being the oldest guy in a room full of young people is an abhorrent idea to you - well, we old guys are dealing with it and getting the job done in spite of the upstarts.

Don't worry, we know - its penance for all the pain we put our elders through, 20 years ago...
