That's a big oversimplification. The waste is at all levels of the food supply chain, from producer to consumer.

There was an excellent special on Food Network called "The Big Waste" that looked into this, by way of a cooking competition. Here's the description:

--------

First class chefs Bobby Flay, Michael Symon, Anne Burrell and Alex Guarnaschelli tackle one of the most massive problems in food today - waste! Divided into two teams, with only 48 hours on the clock, they are challenged to create a multi course gourmet banquet worthy of their great reputations, but with a big twist; they can only use food that is on its way to the trash. The chefs' hunt takes them from grocery aisles to produce farms, and orchard lines to garbage piles, as they attempt to source enough ingredients to feed a gathering crowd. Bobby and Michael square off against Anne and Alex, as they challenge their views of food waste and how and why it is created.

--------

Some examples of things I remember them finding and using (I may not be remembering these completely accurately, so if someone else watched it, please jump in with corrections):

• Fruit at an orchard that was sized or shaped wrong and so was missed by the automated harvesting machines

• Fish at a fish market that was bruised or damaged.

• Cuts of meat that weren't used in any of the items in a restaurant that did its own butchering.

• Produce from markets that was old enough to have lost some color. It's still fine culinarily, especially for any dish where it isn't important for the presentation, but it doesn't sell well compared to the colorful stuff so the markets clear it out to make room. (I believe this was the food that the blurb is talking about from garbage piles--although the chefs did not actually get it from garbage piles. They got it from the market employees who were carrying it out to dump it on the garbage pile).

It was quite revealing. The chefs produced meals that would have been quite at home on the menus at any top fine dining restaurant, all with food that was considered waste before it ever reached a consumer.
Why would you throw uneaten food in the trash? Just put it in the fridge and eat it later.

Please do write about it. I'm pretty interested in this space as well, and I'd love to hear some other people's real-life use cases.

A couple dangers with "track everything" apps: (A) the app may track nothing well, and (B) it may be exceedingly hard to communicate its benefits to people. On the other hand, there may be some significant benefits to a having a data hub for personal metrics: easy cross-referenced reporting, etc.
This. Is. AWESOME. Let me tell you what this is useful for by telling you my story:

I'm a pretty fast typist (80-100WPM on TypeRacer, usually) and I really never put much thought into my typing, since it was good enough. But I recently started paying attention to the kinds of mistake I make on Typeracer, and realized that I have certain combinations of keys which I don't make using the "home row" of the keyboard, but rather, move my hands to make. Every time I hit one of these, I have a 50/50 chance of not getting back to the home row correctly, meaning I have a 50/50 chance of throwing off my typing.

And I am a heavy VIM user, by the way, which means I am very used to doing everything from the home row, including every navigation you can think of. I even have AutoHotKey scripts to give me vim-style navigation everywhere in windows, so I never have to move my hands.

Now with this program, I finished running an example and noticed 2 shocking things:

1. There are a lot of keys which I'm not used to typing from the homerow, which happen to show up a lot in regular Python code. For example, periods (.). And underscores. I was used to shifting my hand to type these characters. I don't notice this during every day work, since I'm actually programming, but I did notice this while playing a program specifically designed for typing.

2. At the end of the program, it gives you statistics, and I found out that I was only about 48% effective, meaning 52% of the keystrokes I made were accidents that had to be backspaced out. This is a lot. Part of it is "first time with this program" bias, but it still means I have a long way to go.

Anyway, I recommend running through this program, it will probably teach you a lot.

P.S. Just one bit of constructive criticism: the way the program presents mis-types is a little annoying, and hard to follow. I recommend doing the same as TypeRacer, that is, have the "mistaken" keystrokes be visible somewhere, so the typist is very clear on how many keys he needs to backspace out. This is much closer to how people type in the real world.
His point isn't particularly controversial, air security has gone too far.

But he was looking for trouble by wearing that shirt, in his words mocking the "over-reactions to terrorism by the general public". He comes off as an angry person who doesn't sympathize with the genuine (and obvious) fears people may have. Ultimately he weakens his own point by acting so ridiculous; he gave the TSA and Delta a reason to mess with him.
Thanks brudgers ! Is it okay to ask for the stock option agreement before joining the company ?
A DNS requires people to agree about who owns a certain identifier, which would be problematic in a decentralized system (though there are proposals like namecoin).

I think a better system could be publishing a triple (name, keyfingerprint, current-server) on a shared datastore (e.g. DHT). The user doing the search would still need to find some out-of-protocol way to identify the right person, though.

EDIT: Kadmelia on Emule is a working implementation of a similar system to what I described, but for files instead of users.
So is clinical significance determined in part by perceived significance? I feel that a potential 2% risk of conditions as serious as those mentioned in the article could easily influence some people towards choosing to have kids at a younger age.
> he gave the TSA a reason to mess with him.

So much for free speech.

Seems they are very secretive with this stuff too, nobody even knows how many app reviewers they employ, or where they're based out of.

Ask HN: Feedback on Business Idea -- Upscale Indian food Ramen style
I want to start a line of Indian food, kinda like Ramen noodles, but better. The concept is simple but I want some feedback on the concept. Also, if you are near Palo Alto, CA, you can pick up 5 of my lunch pouches for free in exchange for your feedback; I can accommodate up to 10 people for this free-lunch offer. My email address is in my profile.

The details:

-	You will get a small pouch of good quality Indian food with lots of vegetables.

-	The food will be vacuum dried like Ramen noodles. Just add water, microwave for 2 minutes and eat. Bowl & spoon not included.

-	The food will be tasty, nutritionally balanced (unlike Ramens that are very low in nutrition and very high in salt), and filling.

-	Low salt, zero cholesterol, low fat, high fiber, full of vitamins, lots of vegetable protein.

-	Only whole grains and organic ingredients. No meat, eggs or fish – so more eco-friendly. Could contain nuts and milk products. Absolutely no preservatives.

-	Sample menu for a week (5 lunches):

o	Three-grain soup with dark greens – spinach, kale and mustard

o	Couscous with spicy peas, carrots and potatoes.

o	Cumin rice with chick peas, green beans and red onion.

o	Semolina soup with spicy lentils.

o	Aromatic fenugreek leaves on a bed of cracked whole wheat.

I know that you can not give me feedback on the taste of the food without tasting it. But you can give me feedback on the business idea. What would you pay to have this kind of food delivered via USPS at work or at home 1-2-3-4-5 times a week. One dollar per meal? Two dollars? Three dollars? Four dollars? Five dollars?

I am thinking of charging $25 for 5 lunches, delivered every Monday morning via USPS Priority Mail anywhere in the USA.
What do NASCAR hats and racist tattoos have to do with this?

This person knowing full well about the hysteria around terrorism, bombs, and air flights went out of his way to cause an incident, and is now complaining about "white racists", unfair treatment, and the airlines.

All he had to do was show up dressed in a normal tee-shirt. But this wasn't good enough for him. He had to make a statement. In a cramped space of an airplane, of all the places. And it turns out the other people didn't get his joke.
Maybe if we didn't heavily subsidize all food production we'd value it more.

So this machine learning textbook is applied specifically to big data, in a way that is novel and new?
I'm not sure what you mean here. The working relationship I have with Erin is nothing like my home relationship with Erin.
It would be awesome if they're keeping stats on each language so that we can find out which language is the easiest to type.
The article goes on to say:

"Food production accounts for 80% of the country's fresh water consumption, but the waste of food means 25% of the fresh water is actually wasted."

This provides a solid support for the claim you highlighted. It is likely going to become more and more difficult to deny that access to clean fresh water is a high-priority problem.
There is interest. Lots of people would love to see a modern-day Emacs with a modern multithreaded Lisp dialect. Problem is, Emacs is a local maximum - it is very difficult to move away from its architecture to something useful.

I will be watching this project closely.
Production of food (esp. the processed, high-meat, transportation-heavy sort in the US) has a significant carbon footprint. Global warming yada yada yada. YMMV.

And historically, humans haven't lived with trivially easy access to food. What explains cultural taboos against wasting food. Just ask the nearest great-grandparent from the Depression era.
Don't forget about Centralia, Pennsylvania (http://en.wikipedia.org/wiki/Centralia,_Pennsylvania) where an underground coal fire in a coal mine has been burning since 1962, making the town uninhabitable.
Thanks, I'm glad you found the stats useful. In my initial version, I wasn't requiring the user to correct errors. I was personally getting errors rates around 3~5% , which appear good but seemed too low for the amount of errors I feel I make. Adding the need to backspace and correct keys revealed the true cost of mistyping a key, namely the wasted keys typed before correcting and all the backspaces.

Thanks for pointing out typeracer. I will take a look at it and try to incorporate its error handling.
Racism is one possibility, but so is anxiety about the guy's shirt and his attitude. Not very rational, but a cramped airline fuselage isn't the ideal place for your political protest. A snotty disregard for the concerns of others tends to make them unsympathetic to your point of view.

As for why pilots have the power to boot people, it's because they're responsible for the safety and happiness of the passengers during the flight, and the airline is there to make money on slim margins, not to serve as a public utility. Unless an airline engages in systematic discrimination against a protected class of people, then pilots will generally be allowed to appease the majority of paying passengers.

What an immature little creep. There are plenty of people who are nervous about flying but who have to do so anyway due to family or business or what-have-you. So he shows up in this shirt-- why?? What's really the point? To get in the TSA workers' faces? To look like a tough guy to the scared grandma, who needed one less thing to worry about on the flight? Fuck off.

Kudos to the pilot who made a decision based on the comfort of the passengers. Let him walk. It's the same decision pilots make when they dodge a little turbulence. Safety? Not at all. Comfort of the passengers. Easing their mind. Pure and simple.
Easter-egg? There's menu link on every the main page.
The irony is that terrorists will try to remain innocuous and a guy like this is less likely to be dangerous than average.
"If the press passes on a breathless press release that turns out to be false, they just point the finger at somebody else, but in the meantime, they've driven traffic to whatever organization they're working for."

I think this is overwhelmingly the toughest problem to solve here for any mainstream rag. Take the Sydney newspaper mentioned in the article for example. If their competitors publish the more dramatic version of the story replete with the sensationalist headline while the Sydney Morning Herald in an attempt to maintain some semblance of journalistic integrity don't, guess which papers the public are going to buy. It's obvious where the incentive lies.

Unfortunately the reality is the public isn't going to change as it is in human nature to pay attention to the more "surprising" news (Tiger! in caveman days). So if the public isn't going to change and the market rewards yellow journalism what's left? Regulation? I don't know.
It's because when the plane pushes back from the gate, the pilot is in charge and is responsible for the safety of everyone aboard. Much like how a captain at sea is responsible for everyone on board his ship (and is held accountable should tragedy strike).

It's not a republic or democracy when you're on his plane. What he says, goes.

I'd imagine the reality here is like many other times someone got "uppity" or "snarky" with people dealing in public safety: his version of expressing contempt for the situation was interpreted as belligerence and a lack of willingness to cooperate in the establishment of security.

I get what he was trying to do. I even agree with his opinions on the situation. But if that shirt represents the attitude he held in the whole encounter, it's no surprise things went to shit.
I am! This is good idea. Keep an eye out for a blog post...
It has followed me now. So problem solved. I also noticed in a few places on the site where it says "we've turned off autofollow"... All good.
You would prefer Facebook or Twitter? Or that they implement yet another authentication scheme and store their own accounts and credential database?

There's no free lunch. The OAuth providers are, on balance, pretty good at what they do and a better choice for account management at small sites. This one happened to pick Google.
For movies a histogram may not be helpful (other than highlighting polarizing films), but I find it invaluable for electronics. While I also read reviews, I find that with electronics 1 star reviews (and sometimes 2 star) are usually given for DOA or other serious failure. I can do a quick calculation of defect rate by calculating the percentage of 1 star reviews. If it's 20% (or above norms for that product type) I avoid it. And yes, I realize that the reported defect rate is likely to be higher than the actual defect rate, but it's far better than nothing.
Producing an interesting, well-functioning, nicely-designed app is the best way to improve your chances of getting featured. There's no guarantee, but half the battle is really just standing out from the incredible amount of crap apps released on a daily basis.

My first app, Foodmatic, actually got featured in New & Noteworthy as well when it launched. Unfortunately, sales fell off as soon as the feature ended and the app was kind of a failure haha. But no doubt getting featured can be a huge factor in the success of an app.
I think both are unfortunate, since it ties your identity to your current provider. I'd much rather see a truly decoupled system, even if it didn't provide a "friendly" user id, but only an hidden fingerprint. People can just search for name and other data anyway.
I'd hate to see what the figure is for buffet's only
They have a lot to do with it, actually. My point is that if some speech, communicated by wearing a T-shirt and nothing else, is actionable, then perhaps other forms of speech should be actionable, too.

This person did not "go out of his way" to cause an incident. He wore a T-shirt and that is all he did.

"Making a statement" is ok. This is America. We supposedly protect that right, even when we do not agree with the statement in question.

"Hysteria" resulting from events that happened 11 years ago and which will never occur again is not an excuse for abandoning that principle.
"So is clinical significance determined in part by perceived significance?"

It's determined entirely by perceived significance. For each type of drug, there is usually some agreed on metric within the field that determines what constitutes clinical significance. E.g. a blood pressure drug might have to lower blood pressure by 5% or 10% or whatever. And often times the metric isn't even relevant, as in the case of a reduction in blood pressure vs. a reduction in total mortality / morbidity.

However, at the end of the day what the academic community considers clinically significant doesn't really matter, it's your own preferences and values that should be your guide. Especially since in practice everyone is basically out to trick you in order to make more money, from pharma companies to newspapers to academic journals to professional organizations (AMA, APA, etc.), etc. That's why it's important to really understand this stuff forwards and backwards and to keep your wits about you.
Why is it a high-priority problem?

edit: I am genuinely curious. All I can come up with is increasing population which doesn't seem like much of a problem since demand for food will also increase, food prices will rise and waste will diminish.

Whenever I'm subjected to TSA, I'm an angry person and I don't sympathize at all with the fears people may have. Genuine though they may be, they are ridiculous. You are safer flying on an airliner than you are sitting in your living room, and that's not the TSA's doing. I shouldn't have to respect people's ridiculous and baseless fears in order to exercise my right to travel.
Exactly. The moral of this story is clearly not to wear t-shirts joking about bombs, terrorists, or killing, when you know you're going to be boarding a plane.
This isn't even about safety. It's the pilot's job (if he wants to keep it) to make the passengers as comfortable as possible also. That's why they dodge turbulence. Except in extreme cases, it has nothing to do with safety.

> Or that they implement yet another authentication scheme and store their own accounts and credential database?

Yes, either this or openid. I don't have an account at google. I don't want an account at google. While it's a lower barrier than a facebook login, it's still enough that I'll bounce off the site when I see it.
From the docs:

"If the app does not respond with 2XX, then the server should try again later."

"Shirley has her client in maintenence mode; jerrold.me will attempt to deliver the notification later using an exponential backoff algorithm."
You know, there was a time when being in 'stealth' mode was because you were so cool that you needed some time to get ready before you started taking on customers. Now its a proxy for 'we are filing a bunch of patents, hang on'

The problem of course is that 'stealth' mode can lead to 'designed in a vacuum' mode which means you don't get the benefit of people making observations that in hindsight are obvious.
I was referring to some decisions we made in our server implementation. A big part of our app is the ability to share your lists with other people and see changes in real-time, which is mediated by our servers.

Science does in fact allow for magic. If it were true that saying several syllables in succession accompanied by appropriate gestures caused lightning to shoot from your fingertips in a repeatable manner, science could measure and classify it.

I took Prof. Mohri's class this spring, and we actually used a draft version of this book. I agree with you that it's very theoretical, but Bishop, Mitchell, and the other ML resources don't address learning theory. VC-dimension isn't for everyone, but if you need to know about it, this is the book you want to use.

There's also the added bonus of this text coming from Prof. Mohri et al.'s experiences at Google, so there's a lot of discussion about online algorithms and ranking (which you don't see in many other places).
That's not a why. That's just you stating the fact, and it's non-responsive to my question.

In this case, the plane had not pushed back from the gate. The pilot kicked this guy off before the flight. I think it's reasonable to ask why a random, unjustified passenger complaint to the pilot should override the TSA's screening process.
