Yeah, there's a lot of disinformation about health running around. I've been researching nutrition informally for about 10 years. The only really useful pattern is that most of the disinformation is profitable to someone. It's frustrating how much that disinformation prevents people I know and care about from making even basic improvements to their diet.

As for sun and cancer, sunlight is actually more helpful than harmful, and policy recommendations suggestion avoiding the sun are causing problems. http://www.news-medical.net/news/2005/03/23/8666.aspx You can get Vitamin D from supplements though.

For the rest of the things on the list, The China Study is where I suggest starting if your just getting into health and nutrition, and prepare to be blown away.

I don't think anything I mentioned is particularly disputed or hard to confirm with some Googling. There's opposition though. The dairy industry certainly won't tell you that homogenizing milk puts plaque in your blood vessels, for example. The meat industry doesn't want you to know about sodium nitrate, etc.

My argument is just that, for most people, there's something basic they're already doing routinely to sabotage their health, so trying calorie restriction without fixing those first is bad optimization.

neat stuff! Thank you...

Programs that solve real world problems are - for me at least - a lot easier to get in to and to learn from how to build things in a certain language and perl is no exception.

I like to read such stuff, much like another person would read a book I guess. It's a great way to learn.

Probably mostly the reader, perhaps a little themselves.

Really, your question could be raised in response to virtually any person or entity with a clearly identifiable ideological stance of which they are frequent exponents. Just about anyone with a philosophical disposition and/or a discursive character - a tendency toward narration - is a candidate for, "Why do you keep saying what you think all the time?"

I guess it's because that's what intelligent people or groups of them who conceptualise themselves to have some sort of intellectually coherent purpose do.
I have to disagree; if it was that easy to replicate Mint's success, how come Mint can worth that much of money, and why people are using Mint's service instead of Your-Mint-Clone?

Your comment reminds me of the remark ( either here or on reddit, I can't remember) that StackOverflow is easy and can be cloned in a week, because the underlying technology is not hard to replicate. What you forget is market often pays a premium for the database, not the technology. Getting the technology to setup is easy, getting the subscribers, is not.
"Fuck you money" is a bad name, then.

But I think it's stuck because, for a lot of people, it is buying a Caribbean island money; it is their chance to say "fuck you" to everyone who still has to work for a living. Their ambition is to display their wealth conspicuously, and otherwise sit on their asses while other people envy them.

I can't imagine someone working because they want to saying "fuck you" to someone who works because they have to, and especially not to the degree that the perpetual vacationer would. In fact, I can imagine the Caribbean island owner being condescending to the willing, but rich, worker because they aren't projecting the image of a rich person. Rich people don't work; but this one does, so he's a misfit.

I think for the crowd that gathers here, "fuck you" money should really be called "next level" money. They likely have that ambition you refer to, where getting rich is just a means to even greater ends. It's hard to quell intrinsic ambition, even if one of the hopes of that ambition has been fulfilled. And it's hard to develop ambition, even when one has the means to become so, but didn't rely on ambition to get there (e.g., lottery winners, etc). This is why most people call it "fuck you" money; it's where they can stop faking ambition and show how little they actually had before getting lucky.
Ask HN: Review my email collaboration app - MooGroups
I first posted here a couple weeks ago and since have gotten some good feedback and have revamped the UI to make it easier to understand and more inviting.

MooGroups is a group email collaboration tool that gives you an instant mailing group for each conversation. It provides embedding polls, archived attachments, all directly in your email and without having to signup. It's built for group email conversations that don't need a formal group service (such as google groups).

Let me know what you guys think!

Thanks!

Not necessarily, even on a uniform memory access machine; perhaps you pass around a reference to an object that is located close to the data you want. On a non-uniform memory access machine (which is to say all of them these days when you take cache into account) message passing and the message passing formalism can actually save you time.

Anyway, I don't a priori object to shared data structures, but it is important to remember that they are inherently dangerous and the amount of shared memory should be sharply limited to that which is actually necessary, rather than blindly making everything shared.

Lock free data structures won't protect you from deadlocks or races necessarily; they mean you won't have to lock, but you can easily accidentally write a situation with two processes mutually waiting on each other.
The problem isn't the dragging to the application folder itself. I've seen my mother do this and it went fine.

He problem is that the application isn't moved, it is copied. After putting a copy in the Applications folder, she just drags the application from the disk image to the dock. Now she has two copies, and uses the slower one in the disk image. Sometimes she even drags the disk image to the Application folder too. It's all very confusing

I agree that the disk image system is very confusing for the casual user. The zips seem to give a much nicer interface
Any particular reason why they should be?
There’s a couple of good package management systems for OSX, if you’re looking for servers/frameworks and command-line apps. Seeing as servers & frameworks tend to be more complicated to install that dragging an app to the Applications folder this suits me. I use http://www.macports.org/
> The programs can gauge market response and, using pre-programmed manoeuvres, called algos (for algorithms), catch the demand before the public (that’s YOU), grab lots of it cheap, enter and cancel hundreds of small orders in order to find out the public’s limit for a stock’s price and dump all it’s holdings to them at a penny below their limit, but above what the computer paid for it, for a small ($10,000, say) profit, in a matter of seconds.

This isn't flash trading, this is just high frequency trading. All the stuff mentioned in this paragraph about "cheating" has nothing at all to do with flash orders. bellringer seems to suggest that high frequency trading is "cheating". This argument that guys with faster computers and better connections are beating at home traders is nonsensical. If I tried making cars at home in my garage, of course Toyota is going to beat me. They have state of the art factories, trained engineers, and years of experience. Toyota isn't cheating. Similarly, Goldman Sachs, along with lots of smaller guys, has huge computing clusters, blazingly fast and connections and they're going to beat you, a guy with a laptop at home. But it's not cheating.

True, but the world would probably be better off if Mint were an independent company headed for an IPO. I guess the question is why the existing system of incentives discourages this?
Perhaps with this feature we can finally use ASCII art to navigate through our code!
I don't get it - why would you want to "not work"? What do you do then? If I want to sit on a beach and drink, I can do that right now - if I want to play games all day, I can also do that right now. Work is the game, if I stopped working, I'd be bored out of my mind.

That's all true, however this particular one contained a nugged that is of some value:

"Real entrepreneurs cut through the hype - they know what is essential. Their sense of pride doesn't come from who they know or what others think - it comes from making a contribution and creating value. They will do it their own way - which won't include wads of cash from outsiders. They figure out how to do more with less by using their brains, guts, and sweat.

Disruptive new entrants that topple giants belong to determined, frugal and independent minded entrepreneurs - and in their minds, the true stars are the customers they serve and their tireless co-workers who help turn dreams into realities."

That sounds pretty good to me.
Time is a global variable (and hence an implicit parameter) to any function that manages state.
Unfair comparison. I never said it was easy to clone Mint or tried to trivialize Mint's achievements. On the contrary I emphasized the word "relatively". My argument was that Yodlee is the senior partner in the Mint-Yodlee collaboration. I am also guessing here that Intuit has far more access to financial data (banks as well existing quicken databases) than Mint-Yodlee.

EDIT: rephrased for clarity.
Not only that, it also shows you that it's possible to make a bundle without sacrificing your ethics.

What I do wonder about is how Steve Wozniak would fare if he had to do it all over again in todays environment, it certainly feels as though the world of IT has become a lot more aggressive.
You might even harness the power of paging in order to pass messages, with a copy-on-write exception to make the actual copying as lazy as you can. And if you're working on page boundaries copying can be done using DMA controllers.

He is an expert on creative problem solving. I doubt you are in a position to dispute that. And how long do you think consumer 3D hardware has been mainstream? Carmack's career spans a lot longer than that.

I wonder if you would accuse an artist who spends lots of time exploring dead end ideas of doing grunt work? Would you dismiss an artist as adapting WELL-KNOWN ideas if they allowed you to view someone else's work in a brand new, unexpected light?
EXCERPTS:

DoubleClick Ad Exchange, will greatly simplify the process of buying and selling display advertising, allowing many more publishers and advertisers to benefit from it.

But both in display advertising and in advertising exchanges, Google finds itself in the unfamiliar role of underdog. As one of the Web’s biggest publishers, and a seller of ads on a network of top sites like eBay and hundreds of newspapers, Yahoo is the king of the display advertising business.

The new system will automatically allow hundreds of thousands of advertisers and publishers who now use Google’s AdWords and AdSense systems to run their ads and ad space through the exchange.
I had a course that employed the same system. The course wasn't about debuging or real world applications, it was about algorithms. The task was to implement an algorithm correctly. If you did not implement the algorithm correctly, the test cases would fail. If you did not use the correct data structure, the test would time out. That's what it's all about. No specific clues were given so you can't do workarounds taylored to the test cases, or god forbid, hardcode the expected results.

You could do as much testing on your machine as you'd like, with your debugger of choice. And when you are sure you understood the algorithm and implemented it correctly, you can submit.
I think you are right. I got them mixed up. Clixtr did look pretty slick and we couldn't try it out for free (which they've since changed). CitySourced was similar in that it didn't even have an application ready.

Thanks for pointing that out.

Rather than the big picture of long term health effects, my first impression on the brain regeneration issue. You suggest diet changes that could certainly help you live longer, but do they help the brain specifically to stay healthy?

The other point of interest (to me) is that maybe buddhist monks and indian ascetics do have something else going for them.

Coudnt agree more. I'd say FU to FU money.

FU money is the worst reason to do startups. Most startups which are driven by FU money as the goal, dont really get anywhere. They destroy lives and drain the best years of some of the brightest young people. The ones we hear about going big are really a very very small fraction - you are better of buying lottery tickets if you really want FU money.

Do a startup by all means, but do it for the right reasons. There is no better life waiting for you after you get FU money. Do a startup only if running one is the best use you can think of your life.
These tests are completely useless, since most of the measurements are done at a point where response time has already degraded unacceptably. I don't need a web server that performs slightly better when massively overloaded.

The sweet spot to measure is between a response time of 0s to 1s. After that, you need to be looking at getting more servers, anyways.

A better benchmark would start by swapping the axes of the graph and asking the question: "how many users can I support while keeping response time acceptably low?"
I don't think it's affiliated. I just got the link from Amazon myself.
Your belief that selling ads is not valid or useful to the user never ceases to amaze me.

You sell a few online webapps, and get a full cut.
People showing ads, sell them tech, finance, cars, whatever. Anything that's relevant, and get a smaller cut.

A smaller cut of a massive pie is often better than a full cut of a very small pie.

The website selling directly has a finite (small) number of things they can sell the user. 37signals can sell me a basecamp subscription, a campfire subscription...

The website advertising to the user has a massive inventory they can get the user to buy. Each time the user comes back, there's another chance to sell something new to them.

I'm guessing either you tried advertising at some point and couldn't get it to work for you, or you just hold some sort of weird grudge against advertising and see it as evil.
My book went to press yesterday. The publisher did a whole lot more than just printing it, though. In fact, that might have been their easiest to replace function.

I think publishers will be relevant at least as long as published data is respected more than something I slap up on my website. Seriously, the wikipedia page on me can now be written without getting deleted for non-notability!

I never expected to make any money off this book (my co-author said "Literally, thousands of dollars!" when asked how much he expected to make.) so really, I chose to go through a publisher because editors and layout people have real value, and because a 'real publisher' adds a lot of credibility, which is my primary goal anyhow.

That is an interesting problem: without the publishers, who will function as the givers of credibility, the gatekeepers? Who will wikipedia cite?

edit:
This is an example of a business model where the content is created for free and subsidized by it's side effects. I'm after a reputation, which I will then monetize through my regular business activities. I'm happy to essentially give away the time I spent writing this (hopefully useful) book.

In this case, my interests are mostly aligned with my readers; if the book isn't generally considered to be useful, or at least correct, then I don't get the reputation I wanted.

On the other hand, I could have done the same work, and hired editors out of my own money, then put the result on line. I would perhaps have reached more readers, but I would not have the added credibility of going through a gatekeeper of quality. And would I have been able to hire editors of the same quality? the clincher for me is the credibility, though. Until we have a better gatekeeper, I imagine this will keep authors using the biggest-name conventional publishers they can.

Honorable, but basically flawed.

Your relationship with your friends will change because of something like that, it is very very nice of you to want to share the wealth, but someone that has a sense of honour themselves will either have to refuse your offer or they will accept and it will hurt their sense about themselves.

Should you ever find such wealth be very careful how you approach your friends with such plans. If someone in my circle of friends would make me an offer like that I'd see that as an intrusion, even if it was meant well. Just that you got into some money does not mean that you have the right to 'fix' others lives, they may get a lot more satisfaction out of fixing it themselves.

Giving money away is a very tricky thing to do if you do not wish to change your relationship with people.

But kudos for looking after others, I really appreciate that that would be one of the first things you'd think of.
I remember a year or two ago everybody in the press complaining how Facebook had huge numbers of users but no profits. Now the press struggles itself while Facebook got profitable a year ahead of the plan.

The same thing will happen to Twitter. Today everybody nagging that they don't earn money, tomorrow there will be shock and awe.
I will. Ping me if you get a moment.

Too much money is that money that you had left when you died that you held on to for a day that never came.

Money is a tool, not an end in and of itself. So, yes, you can have too much money.
Your question seems to suppose the idea that the health of the brain is independent and unrelated to the of the overall health of the rest of the organism. This has historically been a common belief in western medicine but evidence to the contrary is now abundant.

Studies I have read suggest the adult brain is able to generate new cells in the presence of these conditions: being required to learn something new and challenging, physical exercise, and adequate nutrition.

Some of the food ingredients most mentioned in health literature supporting brain health and development are omega oils, especially DHA/EPA.

The twist here is that in the movies it was all a con, but here in Real Life it is actually working, that is certain people are getting information faster than others for what appears to be risk-free profit.

The last part(risk-free) is what I have a problem with, if you are providing liquidity, then you should be making profit while taking certain risk. The flash order trading seems like a licence to print profits without the risk.

You know, in all my childhood of reading Asimov I never believed I'd live to see this written in earnest (or close enough).
One upon a time, I was at a dinner my university threw to bring together scholarship sponsors and scholarship students. I was sitting at the table with Mr. M, of the Mr. and Mrs. M that were paying for much of my education. Mr. M was quite successful in the construction business and was bankrolling over a dozen engineering students that year. He was in his nineties at the time. [Edited to add: I just checked and it appears he passed away this year. I'm going to send his family a card after I get home from work.]

Anyhow, at one point, my college nemesis (also, through accident of fate, at my university through Mr. M's generosity) was doing his usual intellectual preening and mentioned some numbers he had been working on for his civil engineering project. As I recall, it was how much reinforced concrete he would be needing for some project or other, but don't take my word for that: if physically exists it is Not My Department.

Mr. M mentioned, in a humble and offhanded way, that perhaps Nemesis should consider adding 20% more reinforced concrete so that the structure at issue wouldn't fail.

Nemesis: "Well, I don't know where you're getting your numbers, old man, but in this day and age X is considered enough."

Mr. M: "Well, I suppose it is entirely possible they have improved on the formula since then."

Nemesis: "You mean since you used it last?"

Mr. M: "I mean, since I invented it."

The marginal utility of money is presumably diminishing for any entity. But the curve is stretched when you look at the whole of society (or any larger group) rather than an individual, for two reasons. 1. Having $1M isn't 1000 times as good as having $1K, but giving $1K to 1K people is about 1000 times as good as giving $1K to one person if all the people matter roughly equally. You're not moving so far along their utility curves. 2. There may be big projects that deliver lots of value at very high cost. (The fact that this is possible is basically a consequence of #1.)

I'm not sure this has very much to do with whether the Mint guys would have done better to keep going independently rather than taking the $170M, though.
