That's a good point. You really cut to the heart of the matter—no oversimplification here!—and I applaud you. None of our distant ancestors suffered from poor hygiene. Not was there ever famine, and they never fought among themselves. Life was pretty much perfect back then, if we disregard that fatty and meaty diet.
Have you been to any Buddhist country (Vietnam,Thailand India,etc) and tried any of the faux-chicken/beef/pork/fish dish? It isn't as real as Beyond Meat probably (since it is not made by scientists but thousands of years of practicing vegetarian) but is quite delicious.

There is nothing inherently wrong with processed food. Processed foods could only be considered "bad" if you're actually replacing healthy foods with them.

For example, a can of coke isn't actually bad for me per se, it's just nutritionally useless, and it's taking up 100something calories out of my calorie budget for the day that could be used by something with a higher amount of micronutrients in it.

I don't think any vegetarian or vegan is going to throw out all their veggies and start eating nothing but meat alternatives as soon as a viable replacement comes out.
Ok, so rather than feeding people the genuine article let's feed them some laboratory created faux-meat. That sounds like a great way to be healthy.

I don't disagree that we need to find more sustainable ways to feed ourselves, but we also need to be feeding ourselves quality food that matches our biological needs. Not whatever is most conveniently and cheaply produced.

Beyond Meat is people! It's people!
It seems the goal is in part to replace the animal-sourced sort-of-fake meat that's already a significant part of the world's diet, with a non-animal source that may be more environmentally friendly to produce.

A roasted chicken or a steak is one thing, but a lot of uses of "meat" really only call for some kind of processed product that has a certain taste and texture. Chicken patties at McDonald's, for example, are not actual cuts of chicken meat, but mechanically separated meat that's reformed into a patty that attempts to mimic a certain meat-ish texture. If you can mimic that same chicken-patty texture with a non-animal sourced set of ingredients as the input, I don't see it really as any less natural.

Ask HN: Where do young working professionals hang out?
As a young working professional I'd like to meet others who are in the same boat. But I find it difficult because it's not like in college, where everyone on campus are the same age as you with similar goals. Where can I meet other young working professionals?
Exactly. Your server could query the DB for a bunch of rows from a User table and send the data to your client. On your client you'd have a User model, and a UserCollection that contains many Users.

For beef, sure. But chickens are very quick to produce (2 months).

This is a crappy argument. Chicken inherently has thousands of "ingredients". I think this product actually seems quite simple, considering the complexity of what they're trying to replicate.

EDIT: Although I agree -- I'd always prefer foods taken for what they are rather than substitutes. Then again, I'm not vegetarian.

I'm really starting to believe that these "critiques" of Khan Academy are just teachers and professors terrified of becoming irrelevant.

The question shouldn't be "How well does Khan Academy teach" (well, maybe someday). The important question right now is "Is Khan Academy a better learning tool than most high school and college teachers?". In my experience, the answer overwhelmingly is "yes".

I did have some truly fantastic teachers/professors on the way to a STEM degree, but they were rare. Most were terrible to mediocre, even at a semi-prestigious university. Khan Academy has greatly reinforced my understanding of some subjects, and it's been exceedingly easy to learn some new subjects.

So yes, it doesn't stack up to the top tier teachers and probably never will. But that doesn't matter, because there aren't all that many fantastic teachers and Khan Academy is better than the rest.
There is also Šmakoun, it's basically just pressed egg white. Here is the inventor describing it

The slice is made of pure egg white, that is albumin, which is a source of the most valuable proteins, necessary in metabolism of organs of living organisms. New modern technology of processing of the hen egg white has been developed in the Czech Republic and patented. This technology turns the white into a porous material further processed in pressurised steam chamber. That produces a compact belt of thin layer of material, composed of microscopic fibres. The belt is then rolled into the shape of cylinder, cut into smaller pieces. These are then pressed into the final form of 100-gram slices. Finished slices are vacuum packaged in plastic bags. As final treatment, each bag is re-sterilised in special equipment.

One straight forward example of what paleopathologists have learned from skeletons concerns historical changes in height. Skeletons from Greece and Turkey show that the average height of hunger-gatherers toward the end of the ice ages was a generous 5' 9'' for men, 5' 5'' for women. With the adoption of agriculture, height crashed, and by 3000 B. C. had reached a low of only 5' 3'' for men, 5' for women. By classical times heights were very slowly on the rise again, but modern Greeks and Turks have still not regained the average height of their distant ancestors.

Another example of paleopathology at work is the study of Indian skeletons from burial mounds in the Illinois and Ohio river valleys. At Dickson Mounds, located near the confluence of the Spoon and Illinois rivers, archaeologists have excavated some 800 skeletons that paint a picture of the health changes that occurred when a hunter-gatherer culture gave way to intensive maize farming around A. D. 1150. Studies by George Armelagos and his colleagues then at the University of Massachusetts show these early farmers paid a price for their new-found livelihood. Compared to the hunter-gatherers who preceded them, the farmers had a nearly 50 per cent increase in enamel defects indicative of malnutrition, a fourfold increase in iron-deficiency anemia (evidenced by a bone condition called porotic hyperostosis), a theefold rise in bone lesions reflecting infectious disease in general, and an increase in degenerative conditions of the spine, probably reflecting a lot of hard physical labor. "Life expectancy at birth in the pre-agricultural community was bout twenty-six years," says Armelagos, "but in the post-agricultural community it was nineteen years. So these episodes of nutritional stress and infectious disease were seriously affecting their ability to survive."

There are some life expectancy-related habits of pre-historic humans that no-one is aiming to copy - e.g. attacks from wild animals, frequent warfare with neighbouring tribes, lack of sanitation and lack of modern medicine including antibiotics, anaesthetics, midwifery and general understanding of germ theory.

I’m a huge fan of the Kahn academy videos and in order for it to get even better it needs people to criticize the curriculum so I am a big fan of this article.

I view Kahn Academy as the start to a new type of education that is in its very early stages. Kahn is a smart man who will probably take the criticism and use it to be better his instruction and add supplemental videos etc. I would be shocked if he didn’t add in a 3rd comparing decimals video after this criticism.

Keep up the great work, I know I’m watching.
no, it's a common misunderstanding of the lifespan metric. mberning is pointing out that the 'maximum' lifespan hasn't really changed. The change has primarily come from infant mortality so one possibility is once infant mortality is eliminated we would no longer see gains in life span.
So on one hand you are saying that a pre-historic diet leads to an early death, but you also want to count deaths that have nothing to do with said diet? Not so fast.

Infant mortality has everything to do with medical care and very little to do with the diet. That's why infant deaths should be thrown out when talking about the diet.

If I have 3 people, one died at age 0, one died at age 50 and one died at age 60, the average lifespan is about 36.5. Clearly misleading. I don't think people realize just how high infant mortality was prior to the advent of modern medicine.
Here's the discussion from the last time this was submitted:

http://news.ycombinator.com/item?id=4226099

Discussion there is closed now, so if you have something new to add, here is as good a place as any.
I think you missed the point of the previous commenter.

If you have 5 people who are born on the same day, 4 of which live till 80, 1 of which dies shortly after birth, the average lifespan will be 64 even though 80% of the people lived until 80.

His point was that most of our increase in average lifespan can be attributed to the reduction in infant mortality rather than people living to higher ages.

I have similar second-hand experiences, but really I'm not sure it's different than any other self-study method in that regard. I know people who are doing spectacularly well in things they self-taught from textbooks and online materials (FAQs, tutorials, StackExchange answers, etc.), and other people who have quite serious misconceptions they've somehow picked up in that route.

Khan Academy is interesting to me not really because it's a revolution in learning, but because it's another modality that is better for some people. Some people learn well from written material, and those people have traditionally been the successful autodidacts, working their way through textbooks and tutorials. But perhaps different kinds of materials can cater to other people, with people working their way through a lecture series instead of a textbook. That'll probably have many of the same pros and cons.
How about this as a fix that retains the current design and functionality.

As well as including the fnid in the pagination links also include a pg=1...n item that is only used as a fall-back if the continuation has been garbage collected. That way you retain the continuation design that enables the user to see the list continued in the order that it was on the last page but if the continuation has been collected it takes the most current ordering and returns page n.

If I had the time this afternoon I would have a look though the code to see if this would work but unfortunately don't. Is there anyone here that is familiar with the code base who could asses if this is a simple change?
I don't think that maximum human lifespan has increased as significantly as it seems, but rather infant mortality rates have shrunk so much that our 'average life expectancy' has increased dramatically.

The plan to have it sold at the meat counter is cute in terms of confidence, but suicidal if they want to market to vegetarians. Once you stop associating raw meat with food, it starts looking, well, gross and violent, and the smell is off-putting. Most vegetarians I've known, myself included, try to avoid that section of the grocery store entirely.

So while I applaud them trying to compete with meat directly and potentially sniping some carnivorous business, I hope they will also keep a few boxes for me in the hippie section.

Ask HN: Startup CEO Salary
I'm excited to say that for the first time I have a start up that may get a very decent round of funding ($250k+). The team is myself as a developer, a partner who has helped craft the product from the very beginning and the gentleman that we found who can easily lead us as the CEO. In attempt to sound very nonbiased our CEO is asking for a salary of 180 K per year starting, the other original partner is asking for 40 K per year and I have a solid developer position with another company therefore I don't need to take a dime. I understand that the CEO's position can very easily command a large salary however am I wrong to question his intent for asking that much as well as some level of founder stock?

Nothing formal has been signed so I'm looking for honest opinions from the HN community.

Dammed Tibet: Extracting Wealth and Power from the World's Biggest Water Tank
I've tried this at home. I made chicken noodle soup with it and it worked really well. I sauteed it in olive oil in a pan first, then added it to the broth later.

It withstood both form of cooking fairly well. It browned in the pan and absorbed some liquid in the broth, but it didn't break down.

However, I don't know if this stuff would be grillable. It's not a big chunk like a real chicken breast. It comes out of the package in small chunks. So it'd work great for some recipes but not for things like chicken piccata.

However, I highly recommend Gardein for recipes like those. It comes in the form just like chicken breasts, and works great for recipes that require a large flat piece.

This criticism does seem to be more harsh than is necessary, but I don't see what the problem is in seeking the advice from those with more experience teaching. Khan has created something amazing, but that doesn't mean he is infallible nor that his videos should stay as they are today.

If you read the second to last paragraph, they don't suggest that Khan Academy shuts down, or that he stops teaching. They literally just say, "Hey, it'd be nice if he asked some really great teachers to look over his examples before he uses them to make sure he doesn't confuse people." I'm not an expert, but sounds like it couldn't hurt.
It's still dependent on the outcome of individual events in the game, which are partially determined by luck, right?

Indeed. It's a clever convolution filter, but all you have to do is look at the resulting image to see some weaknesses. The naive tiling approach is even worse. So let's say I wanted to find the image on the Internet that most likely represented the original of some "sudoku encrypted" image?

1. Throw out any images that are strictly smaller than the cipher image. This technique doesn't do any compression

2. Throw out any images that are larger or of a significantly given aspect ratio than the cipher image, based on how many more pixels could have possibly been added to complete the sudokus on each edge

3. Compare the color histogram or some precise additive hash of color values from the cipher image to some candidate image. If the values differ, reject the candidate. This should work because the algorithm as described only seems to shuffle pixels locally in a tile. So the convolution should still have the exact same overall color frequencies. Edges where some pixels might have been filled in may have to be treated differently.

4. Continue this process until you have a reasonably short result of candidate images

You could easily solve many of these issues by using the filter to shift both space and color values and by recursively applying the shuffling process to larger and larger blocks of the image, but certainly the procedure as described in the linked article sounds suspect.

I could actually see this being researched for compression as well as encryption. Maybe try some sudoku convolutions and see if they compress better. If so, compress that image along with the sudoku solution. I doubt it would work but it might be worth a look.
To provide a good case study, I'll share my own personal experience.

I created the website http://drivingtests101.com/, a free driving test prep website for all vehicles types across 11 countries, this past year, as well as mobile apps for 4 countries.

Lets take a look at the website only. I believe the quality of the product is very good and this is proved by reaching the #2 downloaded education app in a country. However, despite this success on the app side, it was very slow on the website side because it was not marketed well, no one knew about it and no one could do find it.

In my experience, it is very rare for a product to become truly viral from the start.

If you want to grow fast, you need to spend resources on marketing to reach your customer, whether it be through paid or non-paid (eg - social media) means, although every case is specific.

For the website, spending money on SEO and taking the time to write a few articles increased traffic tenfold in the first month!

You learn by doing, but I would highly recommend throwing a few marketing things against the wall to see what sticks.

Good luck!
Qt QML Support for KDE's KWin Window Decorations
I think you took something different from the article than I did. They provide a critique, strongly worded at times, but not totally bashing Khan Academy or the general approach. They specify their concerns, and even offer suggestions on ways it can be improved (specifically, examining existing pedagogy and coordinating with some of the top math and science teachers to generate better content).

One of the authors is a current teacher, working with real students. He gets feedback from them either directly (by questions, comments, curses) or indirectly (homework, tests, quizzes) to gauge his effectiveness as an educator. Khan (until they added problems to the site) didn't have this feedback.

Their criticism boils down to a few main points.

1. He uses an inconsistent presentation of algebra and arithmetic work and notation, which could lead to students becoming confused when he suddenly changes it.

2. He uses a poor selection of examples, without offering more or better examples students may develop a mathematical toolset based on a flawed understanding, which will lead to problems further down the line.

3. The problems available to students are insufficient to provide proper mathematical practice and ensure that some of the common misunderstandings are shown to be wrong.
