What's more important, the two pieces of paper he received or the fact that his own arguments clearly depict he doesn't understand? He says:

" Does anyone – even Jonah Lehrer or the neuroscientists he consults – think that the brain, perhaps in cohort with the gut, is making decisions about how much we should eat, on how long we stay hungry and when we get full, so that we don’t overshoot by 20 calories a day. That’s matching intake to expenditure with an accuracy of better than 1 percent. (We consume, on average, about 2700 calories a day, so matching energy in to energy out and not overshooting by 20 calories requires better than one percent accuracy.)"

"...we actually have to be perfect in our matching of intake to expenditure or we’re going to get inexorably fatter (or leaner, if we err on the side of going hungry), or at least we have to average perfection over decades."

His argument is that the body is not accurate to within 20 calories a day. He appears unaware of the fact that this kind of regulation, which I agree isn't possible on a day-to-day basis (the brain never says "don't eat that last 1/12 of a candy bar"), is unremarkable when amortized over time. That is where his scientific inexperience shows. "Averaging perfection over decades" happens all the time and is perfectly unremarkable. He is oblivious to this fact.

This is a fatal error. Regardless of how it fits into his larger argument, he gets this basic and fundamental point wrong. When an author can't get facts like these straight, I become suspicious of the rest of his arguments. And indeed, a random sampling shows they are fundamentally broken. I would not trust him to explain any kind of complex science.
They're nothing special, and I can quote them right here if you like:

To mount a partition:

do shell script "diskutil mount PARTITION_UUID"

Where PARTITION_UDID is the partition's UUID as returned by diskutil's info command.

To unmount all partitions:

try
do shell script "diskutil unmount PARTITION_UUID"
end try

try
do shell script "diskutil unmount NEXT_PARTITION_UUID"
end try

The try is there in case one partition is mounted and another isn't – won't throw an error in those cases.

Just compile those as self-contained apps, drop them in your dock and you're good to go. It's pretty manual stuff, I have to remember to launch the appropriate script at the beginning and end of a task that involves the HDD, but it's not much of a problem, since I don't use it that often. Meanwhile, you get a silent MBP, with a smidge better battery life, since the HDD isn't spinning needlessly.

Looking into auto-mounting the partition when a symlink is accessed, got a SuperUser question going here:

It's called a framework for making an educated decision. Perhaps I should have said 'on your way to optimal health' as one of the largest and most controllable things in our lives is what we eat.

As for 'modernism', I fail to see how knowing exactly what our body is adapted and designed to process is not useful information. Knowing this, which is the basis for knowing exactly what is optimal, you can then make a decision if that whey protein powder is good or bad for you...if creatine powder is good or bad for you...if sugar is good or bad for you...

Also, I don't think ANYONE would argue that diet is the only thing that plays into health issues. Modern medicine is fantastic and has done wonderful things for our lives, but it has failed in the past 20 or so years to provide us the optimal food paradigm.

Just an FYI, I eat this way, my family eats this way...my wife is a doctor..I have gotten PRP (platelet rich plasma) on my achilles (modern medicine...actually, pretty bleeding edge medicine) and we used modern methods for child birth (decreased mortality rate in child birth). Eating as we are intended to eat, and more importantly, knowing what we are intended to eat, in no way eschews modern medicine...please don't create a false dichotomy.
I wasn't aware that not meeting that goal would result in slapping ads on articles.

Also, Wikipedia itself was fully funded a while ago through next year, the foundation was trying to raise money for other projects and programs that aren't the encyclopedia itself.
He's not really polluting the Internet, right? Some people may want to read about logging in to Facebook rather than actually doing it. (Learn by reading instead of learn by doing.) His site is about that.

To me, there is no ethical issue here. It's a website with information about stuff. Do I need information about said stuff? Nope. But apparently someone does.
My dad flew on the Concorde several times for business trips. He was actually on one of the flights that had to turn back to paris after an engine blew out (or something). Considering what happened to other flights, could have been a lot worse for my family...

Inheritance is two language features in one though—It's implicit delegation and type polymorphism. Those two features need not be coupled together like that, and in fact, shouldn't in my opinion. It's not that silly things can be done with inheritance, it's more that people often use inheritance for one of two things, but rarely both: implicit delegation and type polymorphism. Pick your poison, and use the appropriate construct. I'm no fan of implicit delegation when I can get away with not having to deal with it, but I wish more languages would have an orthogonal construct for type polymorphism separate from inheritance.

I bought the 11" when it came out and it quickly became something I don't fo anywhere without. I used to carry my 13" MBP in a nice laptop backpack, but now I have a small satchel bag which can hold the Air as well as my essentials. With 3G tethering it's SO useful to always have a real computer with Internet access at my disposal.

I still have and use my MBP and iMac, but I use them much less. Convenience trumps power 90% of the time.
I imagine most kids find visually engaging things immediately interesting. The initial hook I used to get my sister interested in programming was the Raphael Playground: http://raphaeljs.com/playground.html

I walked her through how to use the reference to do more and was surprised how little hand-holding she needed. She's 11, not 7, though, so this could be beyond your kid's level.

What is your expertise in? My sister asked a lot of 'Why?'s and I imagine your kid will too, my area of expertise happens to be JavaScript (hence why I favor Raphael) so this worked well for me, but you would want to be prepared to have satisfactory answers.
Or raising for the future instead of waiting for the imminent to happen, running out of money, and act in desperation.
What's the big deal? Unlike bandwidth people get more and more expensive to employ over time. Health-care and cost of living are two biggies.
Some stuff is never written because people know it would be deleted. Other stuff becomes harder to find (do deleted articles come up on searches..?)
I think he was actually trying to piece together the background stories for the people who didn't respond to his emails, not find their emails. I don't think the info he was searching for was particularly private either.

For instance, trying to find out the company a CEO worked at before their current one. The problem is that content copiers will produce so many copies of the PR announcement for their current job, it's impossible to find the announcement for their previous job. I've tried doing this exact search and it's very frustrating.
If you'll notice at the end of that video, the projector seems quite bright. If it is effecting the user's vision, a pattern could be because of eye motion, not the actual pattern projected.

I worry permanent effects of bright IR sources myself... I tend to avoid looking at Sick or Velodyne scanners when I'm around them too.
Since a pound of fat is roughly equal to 3500 calories, this means you accumulate roughly 7000 calories worth of fat every year. Divide that 7000 by 365 and you get the number of calories of fat you stored each day and never burned roughly 19 calories. Let’s round up to 20 calories, so we have a nice round number. (In the new book I discuss this issue in a chapter called "The Significance of Twenty Calories a Day.")

He neglects the metabolism one needs to maintain that fat tissue each and every day. One rough rule of thumb is 11/cal/day/pound to maintain your weight. Being 40 lbs overweight thus takes not just his (apparently trivial) 20 calories per day to gain that weight, but 440 additional calories per day to maintain it. If the weight was truly gained in a linear fashion, that's an average of 220 calories per day to maintain it, above the 20 per day to gain it. This is the real math. This is why weight gain and weight loss correspond to gross caloric intake and expenditure. The dynamic equilibrium of an organism's weight is a feedback mechanism in which the mass of the organism appears as the magnitude of the gain on the negative feedback term.

Someone who is truly obese, say someone who is 300 lbs who should 180 lbs, for example, is running an ongoing daily calorie surplus of 1320 calories through diet and lifestyle, not the 60 per day that Taubes would suggest. This is not an insignificant disparity, and this guy's work will be truly harmful wherever it is--help us all--taken seriously.

I could maybe take the rest of his ideas more seriously if he were not so obviously wrong right out of the gate.
It occurs to me that I haven't seen this question addressed anywhere: Is everyone's digestive system, at all times and under all conditions, equally efficient at extracting energy from food? (Rhetorical question.)

To illustrate with an extreme example, lactose is a sugar and carries energy, but some people can digest it (and their bodies will get the full complement of calories from it), and some people can't (it'll get digested by bacteria and they'll get gas and feel unpleasant; I'm pretty sure they don't get calories from it). It is incorrect and stupid to say that an item of food with significant lactose component carries "N calories" without specifying whether the person who eats it can digest lactose. Likewise, with cellulose, I think cows get a lot more energy out of cellulose than humans can.

Also, it seems likely to me that people's digestive systems' performance varies with "outside" conditions in the body. For example, I've heard that being pumped full of adrenaline puts digestion on hold; and subjective experience suggests to me that if you eat a lot of food (over a period of, say, a day), your system will send it through pretty quickly, without digesting it fully.

I suspect there are a lot of other situations in which one's body doesn't get all N calories from an "N-calorie" item of food. I suppose that if that happens, then the remaining part probably will be digested by bacteria, and one may notice symptoms of... oh, hey, there's a name for this, "indigestion". (Though if the amount of left-over energy is really small, then the symptoms are probably too slight to notice. If 10 or 20 calories a day matters, then this may make things unpredictable.)

I suppose one could count the bacteria digesting the food that you didn't as "calories burned", but then that means you may be burning a bunch of calories without doing any physical activity.

Does someone more knowledgeable than me know a) whether these things are really significant and b) whether these researchers take them into account?
The quality has improved dramatically over time. The more recent ones (check out some of the later calc videos) are in HD, and are well-presented, probably scripted beforehand. OTOH in one of the old physics vids his phone goes off part-way through.
Yes, I am not sure why you are continuing to argue - I got it already. Will it help if I admitted that Apple invented sliced bread? We agree that you are convinced of everything you said and we also agree not to investigate anything objectively - we are good to get over this as long as we stick to subjective opinions ;)
> Having recently done some benchmarking of my own code, and from simply running the browsers side-by-side a fair bit, this doesn't surprise me a bit. Firefox 4 consistently comes out 3x slower or worse than Chrome/Safari

It really depends on the benchmark. On the official ones FF4 does very well, on yours apparently it doesn't, ditto the one in the article.

There is little meaning to general statements at this point, when all the major JS engines are quite fast. It really depends on the benchmark. It would be easy, for example, to show a benchmark where FF4 is faster than Chrome, but again, it would prove nothing.
Well done! If you write a detailed account of how you did it, you are bound to inspire a lot more people to try it out.
I also often wonder about the indigestion issue. A few years ago I moved house and found a fantastic Indian kebab shop a five minute walk away. Most evenings consisted of having a kebab and maybe a couple of cans of beer as well. The morning's indigestion was unpleasant but worth it for the tastiness. The real fun was that I was slowly losing weight on this fantastically unhealthy diet, something that the girls I was living with hated me for after seeing what went in :)
I've found them nearly useless. Way too many people giving one star reviews because their 15" laptop doesn't fit in a 13" bag. If you take the time to read all the reviews, you can weed out the idiots, but sifting out the haters and the astroturfers can take longer than just going to a store and fondling the merchandise.
What I still don't get is why inheritance in OO-languages is always the heavyweight version, namely subclassing.

Imho every class definition in Java-like OO languages should create two types: A (by default) public interface and a (by default) private class.

When you want to inherit from something you should then be able to choose if you want to inherit only the interface or inherit from the full class. Every good design already separates interface from implementation, so why isn't it enforced at the object system layer?
Malicious PDF file as a JSON object
I just released a tool tonight that will scan a malicious PDF file, grab as much details as possible about the structure, objects, etc. and store it in a single JSON object. These objects will then be inserted into MongoDB where they can be queried later. The goal is to find better detection methods based on this data.

3 Kinds of Social Wisdom: Wisdom of Crowds, Wisdom of Experts, and Wisdom of...
I just want to make clear that I disagree with you. I don’t know how many people care about UI stuttering but I suspect that there aren’t many. I care about it but I feel very much like part of a minority.

I just wanted to make clear that different people have different priorities.
1. Financial and career

- Payoff, in full, my remaining student loan balance.

- Launch 42 niche online "businesses" that earn (within 3 months of launch) an average of $500-$1000/month.

- Find and join a company that affords me: freedom/autonomy, respect, great coworkers, and interesting problems.

2. Social and cultural

- Donate 10% of every dime that enters my bank account to charitable causes of my choice.

- Refresh social circle to include only supportive, like-minded individuals with goals similar to my own.

3. Spiritual and ethical

- Listen to Brainwave Entrainment audio and meditation tapes for 30 minutes EVERYDAY, preferrably before going to bed.

- Listen to online sermons as a baby step to getting back in tune with my religion, and overcoming the "fear of what others think."

4. Home and family

- Stop hating my mother for spending the money I sent to payoff student loans.

- Buy a 4b/3ba single family house (2500 sqft or greater) by the end of Q2 for atleast 5% less than the going market rate.

5. Mental and education

- Read self-help and personal development material for atleast 5 hours each week.

-- Subscribe to and read atleast 100 publications related to the startup, software development, and marketing categories.

-- Read 1 book each week on any of the following topics: starting a business, software architecture, online marketing, personal branding.

- Attend 1 personal development seminar.

6. Physical and health

- Cook my own meals by the end of Q1 2011.

- Drop bodyfat percentage from 15.4 to 11.

- Gain 25lbs of lean body mass.

Not even done yet..

Chains have very real problems and frustrations that crop up often- when used on motorcycles. When it comes to bicycles though, I suspect it is the other problem with chains that drives people;

They aren't pretty, symmetric, or aesthetically pleasing. Strangely, this is apparently a very serious problem for many people.

Note: All the problems with a motorcycle chain apply to a bicycle chain, but motorcycles travel massively greater distances, at higher rates of speed, through tougher environments, while transmitting anywhere from 20-400x as much power as a bicycle chain.
1. LLVM is not portable. PNaCl is trying to make it so, but it's a work in progress.

2. A 'universal' payload with ARM and x86, would just work on them. What if in 5 years we have new architectures? Only supporting ARM and x86 would hold back innovation there.
We are.

We need java developers with math backgrounds, as well as operations folks.

I am not sure whether you are trolling. No, that does not mean you get a raise that multiplies it by range of 1.25 to 2.
It is pretty clear that digestion varies dramatically from person to person, and from moment to moment for the same person. You hit upon two major things in your question; what flora are in your gut, and how the rest of your body is.

Anecdotally I've noticed I can change my stomach on purpose by what I eat, and rebalance the flora. For example I used to eat Tums all the time to deal with acid indigestion. Then I did a 3 day fast at the suggestion of my mother in law, and found I was free of indigestion for months after that. Now whenever I find myself getting heartburn more than a couple times I do a fast and it clears up for awhile.

There is increasing evidence the balance of flora also contributes to how you process food, and can contribute to greater development of fat when out of whack.
In order to get a grid after-image [...] you'd have to be inches away from the device so that several different beams were all entering your eye through your pupil.

Not necessarily. Kinect beams could reflect of your room onto your monitor, and back onto your retina. I think you might be able to achieve an afterimage in a laboratory, if you tried really hard:

- find some material that is fluorescent in visible light when irradiated by the IR that Kinect emits

- fill your room with it.

- seriously darken your room.

- play a game that has a very dark screen.

- stare at the screen for a couple of minutes while Kinect is active, keeping your eyes focused on one spot.

Of course, all of these are unlikely to be applicable here. Also, you will probably have lots of trouble finding that fluorescent material, if it exists at all; IR light is lower-energy than visible light, so the material will have to do multiple-photon absorption.

It was an aphorism, but I'll grant you that.

But a backup that would take the same effort (a $10 alarm clock) using entirely different hardware and software would be significantly more robust than just using another iphone.

The 747 has two sets of controls and four completely redundant hydraulic systems for the control surfaces, rather than two controls for a common hydraulic system. In the cockpit it looks the same, but the backend is far safer.

Two iphones share all their software and hardware. Any bug in either would affect both. Additionally, they're both connected to the internet. If they both get a SMS of death, or if AT&T's NTP server decides to tell everything that connects to it that it's January 1st, 1970, 12:00AM, or if someone with a warrant tells them to remotely shut down both phones, etc etc etc. In contrast, the only thing I can think that would take out both a cell phone and a clock radio would be an EMP, or an explosion in the same room.
Just to make sure I understood this correctly. Is your suggestion that low education, low income, obesity are all explained by personal irresponsibility?
I like what he's doing. Running a few quality keyword targeted content sites might be more lucrative and helpful than trying to invent the next facebook or twitter. It's by no means as glorious or innovative, but it's pragmatic, provides you with revenue and in his case might actually help some people.
> Secondly, stating that weight gain is due to eating more calories than you burn is neither tautological, vacuous, nor inane. It might not be satisfying to the author, but it is a cogent and useful explanation of why people gain weight.

It's an excellent starting point, but it might not be that useful by itself unless you like working against your body's self-regulation mechanisms.
My favorite part is wondering how exactly the front wheel is supposed to support any weight. Besides the part where the hoop will buckle from the weight being applied at the top-dead-center, how exactly is the force transfered!?

Not to mention the rake looks too small (aka zero), and the axis of rotation of the handlebars is not centered with the actual axis of rotation of the front end. That will be fun to pilot.
Looks like they want to have only the best candidate, but for maintaining a horrible codebase. Obviously a position that's hard to fill.
