Are you trying to imply that consumption of animals and plants/fungi is the same? What's the point of that argument? I mean, come on, I'm vegetarian and I kill mosquitoes ...
The video mentions that the production ready kit will be about the size of an airplane carry-on bag. I think for most cars it's possible to fit a roller carry-on bag, a stroller, and groceries with ample room leftover.
That was my thought as well (see my comment elsewhere in the thread). I wonder if this could be used as some kind of fixed sparsity encoding?

The answer to this, at least in my case, is better than my children's primary school teachers by an order of magnitude.

I get the feeling that most of the people bitching are paid teachers who are losing their cut.
Great example to support your thinking. I hope that I understand that correctly - you are saying that product as a some bigger thing then some code is the main thing startup should focus on, and you have to get >1 in "expirience" with it? :)
I think one of the most groundbreaking ideas they have is "flipping the classroom" [1], where students watch Sal's videos at home before class for homework, then in class they work on problems with the teacher and other students. That's where the ability for teachers to track and target deficiencies really becomes powerful.

I found the examples the article gave about students' common misconceptions interesting. I'm wondering whether the tracking and analysis by Khan Academy picks up these misconceptions as well. For example, in one of the examples (8 + 4 = _ + 5) many students answer 12 or 17. Khan Academy should be ideally placed to find such misconceptions if only because their sample size is much bigger than the average classroom.
The antitrust implications for this are massive.

Google would clearly be subsiding the cost of the broadband with advertising/sales from their online properties. If you are someone like Vimeo, Hulu, Netflix etc then you would forever be at a disadvantage to Youtube due to bandwidth costs. Similarly the proven importance of speed in site popularity and conversions means that an entire raft of competitors would again be at a disadvantage. And finally Google would be in a position to wipe out hundreds/thousands of small mom+pop ISPs.

The Google Fiber on its own has competition issues but a free service could just about tip it over the line.
FWIW 4:22 of the video shows the trunk. It ain't small.
Great comment on that: "On the up side, he now has a shelf life of 400 years."
But that's not how fiber works. At some point, it still has to go back to a central office. You can't just connect to your neighbors directly, it all ultimately goes through a switch/router somewhere.
Thank you. The article was not easy to scan quickly - too few paragraphs.

Agreed title needs to be changed. 'Blackhole malware attack spreading on Twitter' vs 'Twitter hit by Blackhole malware attack' two very different stories there.
I assume they mean the typical Linux userland stack.
This seems silly. They "use Sudoku to tackle a different problem--how to encrypt images before sending them".

You know what else works for encrypting images before sending them? Any other encryption algorithm.

Who cares if your "encrypted" image is still an image? Doesn't that kind of defeat the point of encryption? It's obviously just a scrambled image, leaving only the question of what the unscrambled image is. If someone was planning on sending illegal or sensitive images with this, you could probably still easily guess what the nature of the original image was.

It's not like steganography where you don't know there's a message there, or normal encryption where you have no guess as to what produced the cyphertext or what the payload is.
I'm an omnivore, and if this stuff was equivalently expensive, and sufficiently chicken-like, I'd buy it instead. Real Chicken isn't exactly some holy grail of food, it just tastes good.
I have to agree with both of these points. Modern society is so insulated to the ethical costs and environmental costs of meat eating. We have no problem taking our children to go strawberry picking to get their food, but how about taking them to a slaughterhouse to get their McNuggets? And then environmental costs of using 10x-50x the amount of water to produce 1lb of meat compared to 1lb of grains is staggering.
Why would a person who is vegan want to eat fake meat? I find it odd a person who is a vegans who finds even vegetarianism too relaxed would even want to eat fake meat.

I wonder if the opposite could be done to create a fake carrot made entirely out of meat?

Beyond Meat's website has "without the bad stuff (no saturated or trans fat, no cholesterol, no gluten, no antibiotics, no GMOs...and no meat)". How is gluten "bad stuff" unless you have celiac disease?
I believe that regulations exist to prevent the food industry from marketing non-genuine food items as the real thing. I have heard that chicken wing shaped chicken products cannot be sold as 'wings' but must rather be labeled 'wyngz'.
For those who aren't familiar, Mark Bittman is kind of a foodie god; I'm pretty sure organic wheat springs up under his feet when he walks around. Here's the part of Bittman's article about the fake chicken, from back in March (linked from the Slate article):

... at least one new product is a better-than-adequate substitute for chicken in things like wraps, salads and sauces. I know this because Ethan Brown, an owner of Savage River Farms, came to my house and fooled me badly in a blind tasting. (A pan-European “LikeMeat” project appears to be making progress on a similar product, and others are in the works.)

On its own, Brown’s “chicken” — produced to mimic boneless, skinless breast — looks like a decent imitation, and the way it shreds is amazing. It doesn’t taste much like chicken, but since most white meat chicken doesn’t taste like much anyway, that’s hardly a problem; both are about texture, chew and the ingredients you put on them or combine with them. When you take Brown’s product, cut it up and combine it with, say, chopped tomato and lettuce and mayonnaise with some seasoning in it, and wrap it in a burrito, you won’t know the difference between that and chicken. I didn’t, at least, and this is the kind of thing I do for a living. Brown does not see his product as a trendy meat replacement for vegans but one with more widespread use. (His production is at an early stage, but Whole Foods is planning to start using his products in prepared food soon. Retail sales of his “chicken,” which does not yet have a trademarked name, are expected to begin this summer.)

http://www.nytimes.com/2012/03/11/opinion/sunday/finally-fak...

So it sounds like this is a complete substitute in dishes where you chop up the chicken and add strong flavors, and not really intended to be a substitute otherwise. It's not 90% of the way there in all dishes -- it's 100% of the way there in 75% of dishes. And it's cheaper and takes probably a quarter of the resources to produce. Given the size of the total market, that's a huge deal.
You say that, but I think a lot of people are making up criticisms in order to justify ignoring it.

Where i was taught we still had the exact same decimal problem khan has...

The best way to deal with it is through continuous refinement until criticisms are few
In some sectors it can be as easy as it looks. It's just when the playing field is really competitive that it gets a bit tough. Ranking #1 for 'dentist in irlam' will be levels upon levels easier than ranking for 'dentist in london' in terms of SEO. Similarly the cost-per-click in paid search will probably be orders of magnitude apart and optimising your campaigns will be much harder. Choosing the best keywords for what you'd like to achieve is tricky and figuring that out only happened after I dived in - it's likely a lot of what I've learned there is niche specific too.
According to Wikipedia (http://en.wikipedia.org/wiki/Life_expectancy) which pulls its source for "Life expectancy variation over time" from Encyclopædia Britannica and other sources, life expectancy in the Neolithic was about 20 years old. And that does account for infant mortality, but not pre-natal mortality. Do you have a source for "long and robust lives"?
Defending against Web Application Vulnerabilities
I think what you gain from static typing is pretty much that you can compile your programs and run without a fat interpreter.

Note - I am not saying that is the only possible benefit of static typing anywhere, e.g. in Haskell - this is more in line with C, you are doing type declarations to cue the compiler rather than to realize some utopian test-free development methodology.
Great, thanks for concrete example
Thanks, that's what I wanted to know. I was curious because you have to change jobs very often to have enough exprience.

By the way, it worked 3 times out of 3 attempts?

And for that you need the criticisms.

A bit of Googling also reveals that some Sudoku puzzles are invertible, so it sounds like in addition to this problem, you'd better pick your sudoku solution carefully, as it might be possible to recover the key if the number of candidate images is small.
When I finally understood Gödel, in as much as I do (which is probably not very), I found it tremendously relieving: God has laced the world with just enough paradox and unprovability to keep it interesting, and maybe there is something to that gut feeling that we don't live in a grinding, meaninglessly mechanistic pin-ball game.
They need to be more careful about using the word 'cryptography' then. Sure, crypto people and informed laypersons know this is hopelessly insecure, but all it takes is one overzealous intern implementing this in a banking application to cause a huge problem.

What kind of things?

Are you suggesting that flesh-and-blood teachers or brick-and-mortar schools are less likely to spread misinformation or leave students with misconceptions? I can tell you a hundred false things I was taught by "real" school, and some of them are probably just things I think I was taught.
I haven't tried that many Linux distributions, but as Windows users I found regular Ubuntu pretty frustrating in the beginning, while the transition to Linux Mint seemed very natural. So I would recommend Linux Mint for Windows users.
Website Content Strategy
I think that the crux of the argument seems to be this idea that there is a "magic bullet" to fix the education system. As a former teacher I can tell you that if there is a magic bullet it's parent involvement in students lives. No textbook, online video, or even a fantastic teacher is an acceptable substitute for parent involvement as a foundation for a child's educational success.

With that said, I think that KA is an excellent addition to the pieces of the educational puzzle. I've used many of his videos to supplement teaching and textbooks, both good and bad.
Soy (unfermented) is a terrible idea.

"Results: Poor cognitive test performance, enlargement of ventricles and low brain weight were each significantly and independently associated with higher midlife tofu consumption."

"We hypothesize that regular dietary exposure to soy isoflavones over many years during middle life may be associated with the appearance of accelerated brain aging in later life attributable to chronically sub-optimal neural plasticity."
I am with you. Moving back to Gnome2 or XFCE just feels a little odd to me. I constantly find myself pressing the super key to get to the activities overview and then I get a little disappointing when it's not there. There are still a few tweaks I would like to see implemented, but I like it better then every other desktop shell I have seen.
I'd love to hear how you think you're going to regain the enthusiasts' market. Care to say more? In particular, which enthusiasts? The ones who have already (like me) switched to Xfce? Or some other set of enthusiasts? Defining your market is important; if GNOME is going to continue to have a severe case of Mac-envy, I doubt you'll be able to also get back the enthusiasts --- and I don't think GNOME has enough developers to be able to complete head-to-head with Apple.
It's kind of an interesting question. Is it better to educate masses with an inferior product that breeds misconception, or fewer people with a better product that limits misconception?
"Research has shown quite conclusively that pre-historic humans survived on a diet rich in animal products, particularly animal fat."

No, it really hasn't. It just hasn't. This is one of those crazy truisms that becomes difficult to even debunk because it has no science behind it...but the people pushing it do so with such gusto and such complete confidence that people simply believe their unfounded assertions. It's a tiny sect of science deniers that selectively choose evidence and ignore everything that conflicts with their particular preference. The "paleo diet" is based entirely on a fictional retelling of human history, and it's about time it stopped being promoted as "research" or "conclusive".

I've tried a couple of beef and chicken alternatives that were splendid. The trick was to cook it to my liking. Crispy, wet, etc.

I imagine these kinds of foods are ok for transitioning into a vegan. However, I was vegan once, and I took it as an opportunity to discover all kinds of new vegetables and fruits. It was interesting learning to cook with no meat. I had discovered a whole new world of food.

Eating fake meat seems a bit nostalgic tbh.
There are many medical articles published on peer reviewed journals to counter this myth, it has no basis in reality, and has never been proved. One of those xenophobic-anti-Asian myths from the 60s (similar to the one about MSG).

If you can't find them yourself (the Wikipedia entry is a good start), let me know and I'll provide citations.
I completely disagree with the second sentence. There must be a way for power users to get the flexibility they want, while making the product usable by the masses. MacOS does this to an extent, with "Advanced" buttons on some control panels that most users ignore. Why couldn't Gnome do that? Why must it seek to emulate Windows' lack of flexibility?

My wife has not eaten meat or poultry for over 25 years. I do. Once, we were out at a restaurant and she sampled my pasta+chicken dish and got a piece of chicken into her mouth by accident. She did not like the texture and the flavour, at all. As in, the innateness of both in chicken was not appetizing to her anymore.

She will be sticking to her nut and bean burgers no matter how good a fake beef burger tastes (to me).
I'm not sure why the authors are concentrating on 'Sudoku' (which would perhaps better be called a Latin square in this context) because I can't see that they need the property that each 'number' appears once per row and column.

If they want in place image scrambling using grids, can't they just generate a random grid that mixes up the pixels in a square from any (x,y) to some other (x',y') in the same square? They can still arrange for this to be a bijection, it's trivial.

Perhaps they could Google 'permutation matrix'.

The interesting thing is how you generate the grids, and for that to be secure you'd need some cryptographic method. In which case you might just as well encrypt in the first place.
I'm no expert but just an thought:

A sodoku puzzle(requiring only 17 digits for an unique solution) which has an single solution isn't exactly useful for compression.

How I am thinking about this? The article states:

"And since for a 256 x 256 image, there are at least 256!=2^1684 possible Sudoku matrices, it's not easy for an adversary to hit on the solution by accident or even by brute force. "

Compression would make sense if the number of puzzles was something like 1684, but it is here 2^1684!! Which is quite a lot and to be decoded would be even worse than the image itself.

The sodoku puzzle's compression would not be of any practical use not only because they give the data more problems to account for but also because the data would need to be interpreted.

Also anything that uses encryption generally does the complete opposite of compression.

Actually I don't see why they can't put regenerative braking in. The motors double as generators and they already have a connection running to the battery. And the motors are right next to the brakes so they could easily detect when the brakes come on.

Agree with everything. Mouse acceleration curve is the deal breaker for me because I couldn't get it close to Windows feel. The pointer slowdown is too sharp at the end of your mouse move, the pointer itself gets jerky and jumpy when tracking over a small area.

I've tried various free and paid tools, but no joy (OS X Lion). Funny that I have no such problems with trackpad, but maybe that's attributed to myself appreciating the trackpad too much while using it because every other one I've tried sucked unbelievably.
I couldn't read the article because the font size is too small and the left "share bar" gets over the text when magnified.

Anyway, to reply to the "statisfy China" thing, let me tell to the author of this "invention" that he is solving a solved problem: China has a long track record of feeding its numerous populace with doufu (tofu) instead of meat. I was very impressed the first time I saw a countryside market. They were selling big doufu pieces in different street shops, and only one butcher was selling a few pieces of hanging meat.

The trick is to actually use little pieces of pork in a doufu-based dish, and many spices, like the delicious Mapo doufu.

Even when eating meat-based Chinese dishes, like Huiguorou, you will eat much less meat than in a classic Western course.

So, in fact, the solution to the possible future problem of Chinese people eating too much meat is not to feed them with that chicken ersatz, it is to avoid Westernization to go that far.

I have a few proposals in this direction that should be common sense:

- Stop using hamburgers as the logo for food in games, apps and other places. Only a very tiny part of the world regularly eat these nocive things.

- Stop displaying actors eating snacks in movies. (We already stopped showing them smoking, except for the villains). Going at any time to the fridge and eating something out of it is a very recent and nocive habit that should not be shown as the normal "American Dream" life in successful mainstream movies.

- Stop this cliché about disgusting intestine-based dishes or other "un-noble" parts. I am no vegetarian, but I think animal we kill for food should be eaten to the last piece of eatable tissue. In China, we (yes, me too) eat tendon, kidneys, fish tripes and heads, duck tongues, pig feet, everything, and cooked in hundres of different manners. It is healthy: eating meat or fish becomes a pleasure by its diversity, not by its volume.

Antitrust law is complicated. Simply subsidizing or undercutting competitors isn't nearly enough; nor is having a monopoly. For example, it wasn't Microsoft's monopoly that got them in trouble, it's that it leveraged its monopoly on Windows to force a monopoly of the browser (special APIs and restrictive license agreements with OEMs)...not to mention the whole Java thing.

Anyways, if someone came out with free energy or free telephones, I doubt anyone would complain. These are utilities. The internet is the same. Last year the UN even declared that the internet is a fundamental basic human right
