>Wheat contains gluten, a known gastrointestinal irritant, and celiac and IBD patients know that wheat is one thing you want to stay away from.

Yes, and anyone allergic to strawberries know they should be avoided as well.
Assuming you don't need whatever you're sending back up the slope of the gravity well to arrive all that quickly, a solar sail would probably work quite well. When launched that close to the sun, it would maintain all the momentum imparted from the additional early boost as it traveled further out.
Nevermind, I just re-read the text of v2, and it seems more limited in scope that what I previously thought.

> If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed.

I was also trying to thing of some pathalogical edge case in which I release something under an Apache license in order to preempt a lawsuit that I've infringed on someone else's patent... but I guess that doesn't make sense, since that would require that they accept the terms of the license to begin with.

So, I guess that's not really as much of a problem as I thought.

I'm sure all kids are different. We had a run-in with a portable DVD player for a while that was obsessive like you describe. We had to put it away. The power struggle around enforcing moderate usage turned out to be more negative than just extinguishing the behavior all together. The DVD player only comes out for plane trips now.
Try reading the article aga....oh never mind.
It's not a matter of should so much as can. In some languages (e.g. Haskell), functions are curried-by-default; in others (e.g. Lisps), functions are uncurried-by-default. In each of these, I could (if I wanted) write either version, e.g.

-- Curried and uncurried add in Haskell:
curriedAdd :: Int -> Int -> Int
curriedAdd x y = x + y

uncurriedAdd :: (Int, Int) -> Int
uncurriedAdd (x, y) = x + y

;; Curried and uncurried add in Scheme:
(define (curried-add x)
(lambda (y) (+ x y)))

(define (uncurried-add x y)
(+ x y))

Haskell chooses to make curried the default, but allows you to write uncurried functions if you'd like. Lisp chooses the opposite.
>Whether it was brought on by food, I don't know, but the prevalence of wheat in a standard American diet could lead one to believe so.

It definitely shouldn't.
What I'm responding to is the fact that most foods don't contain gluten in the first place and people who are severely allergic to gluten know better than to eat foods in which gluten has been "removed" from the food through some chemical process (which is extremely rare, by the way, I can think of only one such product off the top of my head... much more common is accidental cross contamination which is a constant worry for celiacs and gluten intolerant people).

Celiacs don't even eat food prepared in the same production environment as foods that contain gluten. The sentiment that these people are deluding themselves because their very careful planned and meticulously controlled gluten free diets still contain gluten is preposterous.
EpiPen. Kids should carry them and know how to use them. Schools should not prevent them from carrying them.
Summary: Anakata was seized without warning in Cambodia, shoved on a plane, flown half-way around the world, arrested and imprisoned upon his arrival in Sweden under new charges (alleged hacking of 'Logica') and questionable circumstances (including well timed aid donations and high level, out of the ordinary political exchanges) Anakata has been in prison, largely under 23 hour a day solitary confinement which under UN definition may constitute torture. He and his mother have been trying to gain him access to distance education in mathematics, but prison authorities have denied him access to even a graphing calculator. 225MB of bilingual English/Swedish documents have also been released.
This statement makes no sense. You're not going to use Tumblr because Yahoo! is rumoured to be buying the company? Nothing has even been officially announced.
You knock the gluten avoiders and follow that up by saying you became healthy by staying to the periphery of the grocery store where the fruits/veggies/meats/dairy are (and not the grains/gluten)...

I think you just contradicted yourself entirely.
To pay for the development of children's entertainment. Public television is wonderful but I bet all of us look back fondly on a show that we loved as children that would not have existed without ads to pay for its production.
This is unlikely since the housing market topped 5 years ago and may be actually coming out of the bottom finally (we won't know for a few more years)

Another possibility is that there are companies hiring "software developers" for jobs that most HNers wouldn't find interesting because the level of software development is low and hence has a lower waged associated with the value generated.
"I'm of the opinion that there is nothing wrong, or rather that the population is acting entirely naturally and appropriately given their adaptation to specific evolutionary conditions, which have changed drastically in the last 100 years. I doubt controlling marketing material will have a long-lasting effect, but anything is worth a shot. It is a very serious problem."

Which is it then, 'nothing wrong' or 'serious problem'?
I have an honest question. Do you really feel this way about "pg et al"? I'm asking because these kinds of comments about "pg et al" is really not helping anyone at HN or elsewhere defend against accusations of elitism and exclusionary sentiment.

Ask HN: Did I make a MacBook Pro buying mistake?
I am doing C++, iOS, Web, OpenGL, etc

Currently I have a:

- Early 2011 13 inch MacBook Pro
- 2.3ghz Core i5
- 16gb DDR3
- 2 x 750gb striped (removed superdrive)

Machine works great. My only real complaint is that when using the iOS Simulator I have to scale to 75% to test at 1024 x 768 and I have to scale further to test retina apps.

So I went and bought a new:

- 15 inch MacBook Pro
- 2.3gz quad core i7
- Going to put in 16gb (from the 13 MBP)
- Going to remove the superdrive and put in the 2 x 750gb from the 13 MBP.
- I know this model has dedicated video
- better resolution that the 13 MBP

So this was about $1850 out the door. I can sell my 13 MBP with 2 x 500 (I have these) and the 4gb from the 15 inch and probably recoupe $850.

So out of pocket $1000.

Did I make a worthwhile purchase or should I take it back and do something different?
throwit hardly seems to be talking about a libertarian utopia. Kids are susceptible to advertising. They're also susceptible to what their parents teach them. For many of the first years of their lives, they have absolutely no ability to purchase any of these products for themselves.

Is it really so much to ask that we be allowed to make our own decisions about food? Come on, we're talking about food! Not medicine. Not heavy machinery or automobiles or airplanes or nuclear energy. Food!

Regex is a really powerful tool, but sometimes I wonder just how well people actually understand it as the vast majority of people (myself included) seem to be self taught in the syntax - only learning the bits they need as and when they need it.

The problem is, regular expressions is packed full of counter intuitive idiosyncrasies which make perfect sense once they're explained, but are far from obvious. Take this for example:

s/(^\s+|\s+$)//g

is slower than running two separate regex, like so:

s/^\s+//;
s/\s+$//;

So it does make me wonder the number of bugs that have been introduced to software by bad regex.
I never thought of SQL as declarative or like Prolog.

Look at the different forms of relational calculus (SQL is intended to be basically syntactic sugar on top) or look at some research papers by Fariba Sadri - hell, look at the earliest papers on relational databases by EF Codd. RDBMSs were meant to be logic systems right from the start.

it's also easy to perform a join that is slow

Have you been using MySQL? Use a real database with a working query optimizer eg I know from experience that MS SQL will do its best even when you give it a dog of a query. For example it will re-arrange your "filter" and build a temporary index to make your join go at the fastest possible speed.

If you have a specific use case nailed down you can always make it go faster outside of an RDBMS much the same way that you can always make something go faster if you hand-code it in machine code instead of using a compiler.

But if you can't put that much effort into hand-optimizing things, say because your use case might change so you'd have to change the code, the query optimizer/compiler will do a better job.

> Are there really people who spend their time working on these things that aren't professional mathematicians and who submit flawed papers to math journals?

Yes, as well as people who are professional mathematicians (usually not well known) who also do so.

There is not a flood of such papers, but my thesis advisor, in his capacity as editor of the Proceedings of the American Mathematical Society, gets at least a dozen or so such papers each year. I refereed some of them, and had to explain to these authors why their proofs were mistaken.

Just out of curiosity, I ran the same tests on my Linode (cheapest/1 GB plan) and got impressively different results for 2 of the 3 tests.

My disk speed test was very similar, but my memory and CPU tests were well over twice as fast as the results linked in the article. My CPU is also reported as slower than the test system in /proc/cpuinfo.

CPU:
1 thread: 36 seconds (vs 105)
8 threads: 9 seconds (vs 25)

Memory: 207 MB/s (vs 89)

Benchmarking VPS providers seems problematic, something I'm sure has been mentioned here before. The linked article is still a datapoint, but experiences do seem to vary with this sort of thing. Which makes comparing individual providers difficult, but also points out (IMHO) some significant problems when it comes to relying on virtual systems for anything sensitive to the performance of a single machine.
Yes, but morality cannot be adjudicated whereas legality can.

So, when it's important for a point to be settled definitively, talking about the legality is generally more fruitful than talking about the morality. I suspect that was camus's point.

Should we use the law to stop everything we consider a bad influence on our children? I guess this talk of regulating food advertising proves it isn't just the right that makes "won't somebody think of the children" arguments.
Well, I'm not going to say parenting is easy, it's not. If it helps there is something more fun out beyond his current experience, you will know it when you find it, and you'll be on to the next thing.

As for books, the thing with reading is to get past reading into thinking and once you get there games won't be nearly as entertaining because they are always the same. Something we've done over the years is reading and talking about them. Even simple books like The Animorphs series have things to talk about, or the Boxcar Kids, or any of a zillion books. Good starters are "how would you have told this story?" or "can you create a similar one?" "What do you think character X was thinking?" "Do you think we could build a fire with just a rock and a piece of steel? Lets try it."

As long as you stay engaged, your kids will keep coming back. At this stage they are genetically programmed to seek out your approval (too bad for them, but a critical survival tool in the parental arsenal) Expect more, stay engaged, and if you have the experience I have had you will both enjoy the trip.
The story is too new to do anything but speculate.

I ate dinner in a Burger King last week that had a TV playing The Wizards of Waverly Place.

I was horrified. The main character shows no empathy toward the people around her (she lets some girls eat some spoiled sandwiches that she was told to dispose of, and doesn't skip a beat when they later start vomiting) and insults and physically attacks her brother (knocking over his food tray) constantly without any provocation. She repeatedly mis-uses trite motivational sound bites to deflect blame (announcing, "We could focus on the past, and on whose fault this is, or we could focus on the now" when the fault was clearly her own negligence--that started to make me want to punch her in the face!). And, of course, she constantly uses magic to cover up her mistakes and avoid responsibility.

I'm not even a parent, and I'm mad.
I actually watch Japanese Minecraft LPs - it makes for excellent study material, and is highly entertaining.
I'm not saying he's proposing a libertarian utopia. I'm saying that even in a libertarian utopia, regulating interactions between people who are competent to participate freely in the economy and those who are not is reasonably the province of the state.

I'm not talking about limiting anybody's decisions. I'm talking about regulating interactions between businesses and people who are incompetent to make their own decisions.

>It's not empirical

I'm going to stop you right there and say that evidence is empirical.

I'll believe personal experience and observation over some conclusion from a published paper that used obscure statistical methods, possibly lied, got paid to publish a pre-determined finding and found a 2% significance of some occurrence of something with some caveats thrown in.

The ADA has no interest in preventing or curing diabetes as curing diabetes would end the institution. The AMA isn't interested in getting people healthy and proper treatment because that would eliminate the need of such an organization. The only reason Snickers isn't in the food pyramid is only because people aren't that stupid... yet.

I cant figure out a single reason why this comment was downvoted. can anyone help me understand? genuinely curious please.
I think you forgot the solid state drive. Honestly I would have just paid up for a large external monitor and a solid state drive for the 13" MBP. Xcode is sooo much nicer with a lot of RAM (check) and a solid state drive but maybe you are getting enough performance boost from the striped drives. I doubt it though.

EDIT: Also, I hardly ever use the retina simulators since they get in the way and you really need the device to get a good feel for how an apps feels so I just test on actual devices so you could spend the $1k on those instead too. All that said the 15" MBP is a solid machine. I have two.
Will they let the porn stay?
The reason I didn't go with an SSD is I really have to much data. I am moving more and more to a Drobo and mounting it over SFTP but I am not ready to be limited by small SSD sizes yet.
> It wasn't immediately clear whether Tumblr's board had also approved the deal.

So it's still essentially a rumor. Nothing official has been done. Microsoft may have made an offer but it means nothing until Tumblr accepts it.
Nothing structurally or behaviorally unusual. There has been no new change in the species or some external factor that has caused the obesity epidemic. It's all based on changing external conditions, mostly food availability.

So there's no "disease" to cure, and no mastermind manipulation of the population by forces using [insert latest ideas here].

If anything, this leads me to believe that we'll need to take evolution into our own hands to fix this. Various measures like this could be a useful stopgap. Like I said, beats me. Happy to confess ignorance here (as opposed to seemingly most every other commenter who speaks on this topic) If pressed, however, also happy to provide more speculation.

As an obese person, I can definitely add that the disease metaphor, like the "moral blemish" metaphor before it, in my opinion does more damage than good. People come up with these ideas, then start wrapping them in the conspiracy theory of the month garb. Enough with the evil corporations, corrupt governments, sick people, lazy no-goods. These highly emotionally-charged models of analysis are not helping the public conversation.

For the entire history of the species nobody has had to worry about obesity until very recently. It follows that social structures and the physiology of humans are not the changing variable. The only obvious changing variable is food availability. So yes, obesity is a public health hazard, but it's not one based on some fault with people or social structures. It's simply the result of changing environmental conditions for which the species is ill-prepared.

Yahoo buys Tumblr | miApples
Exactly. The jury is still out on exactly how prevalent gluten intolerance is, but the percentage is definitely a lot higher than most would guess.

A second problem is that there is a whole spectrum of how intolerant people can be to gluten. Some people will simply find they are a little more constipated or gassy the next day if they eat gluten and some will find that they need to urgently visit the restroom 30 minutes after consuming it. Neither of those groups of people would be considered celiacs. Many of the people in those groups go through live oblivious as to the cause.

Unfortunately, ignorance like that of lysol's grandparent comment dominates this debate. It's amazing and a bit scary the number of otherwise intelligent people who blindly assume that what is true for them is true for everyone. It's as if the mere fact that some people prefer to avoid gluten in their diets is a personal affront to them. It baffles me.
These 2 x 750 I have are 7200 rpm.
> You're not going to use Tumblr because Yahoo! is rumoured to be buying the company?

Yes. At least not for a story which reflects badly on the potential acquirer. Makes sense to me.
The way you act to others is not secondary. It really does matter that people exercise self-control and try to act humbly, since that's better to other people. A 'genuine' dick is a dick and not somehow better than someone who is acting like a human through effort.

You may be perfectly clean of inner garbage, and a genuine be-er rather than an imitative do-er. Or since you are almost bragging about this to others who you think to instruct, you may have succumbed to pride just as much as someone who feels good about being humble. It's another layer of the same thing.
Most researchers who publish studies are unfamiliar with the scientific method and hypothesis nullification. Either that, or it's not in the interests of the publishers to properly apply these concepts in their studies. We've gotten to a scary point where "science" is now getting more and more into the hands of the public and become a consumer good purely for consumption in the form of news. People love studies that confirm something they already believe. It's bad for business to dispel myths that people have an emotional investment in.

In race to be first-on-tumblr-acquisition,WSJ publishes questionable headline
I don't think this is true at all ... you use the same query irrespective of the size of the data in the tables. So the size of the datasets is irrelevant except for surfacing performance problems.

In the example you gave you shouldn't have problems if you put the right index on the table.

What really causes the opacity is either (a) the complexity of the query or (b) the guy writing the clearly doesn't know how to write declarative code, so he tries to write
eg procedural code in SQL, with cursors and triggers and other horrors.

If you are in scenario (a) and you really do need to do something complex, I'd pick SQL over VB to do it in any day - the non-declarative style leads to huge code with side effects are more opportunities for bugs to creep in.

If you are in scenario (b), the guy writing the queries really needs to read this:

You're absolutely right! We shouldn't let these petty concerns about the competence of children infringe on our liberties! For too long has the Almighty State been sticking its nose where it doesn't belong and we should do something about all these ridiculous limitations.

Why should it be illegal for children to drink alcohol? Their parents should be permitted to make their own choices with regard to the beverages their children consume.

Why should it be illegal for an adult to have sexual intercourse with a minor? The parents should be permitted to make their own choices with regard to the sexual behavior of their own children.

Down with the meddling of the state! Our freedom is at stake!
Take a counterfactual: suppose Starbucks isn't in the UK yet, and an enterprising young lad wants to bring it there.

Starbucks might license their name, supply chain and coffee brewing methods to this young lad in exchange for a royalty on each cup sold.

Young lad becomes successful, Starbucks is more successful and now the taxman comes. Suppose YL is charging 4£ for each cup and paying a 3£ royalty. YL is English, selling in England, to English, using English money and English banks. Shall we charge him tax on the whole 4£, minus his in-country expenses? Or shall we charge him tax only on his profits, treating the 3£ royalty as a legitimate business expense, and in fact, the very cornerstone of his business?

Maybe you think YL should pay taxes on it all, but I don't. And I don't begrudge the companies who have structured their affairs wisely, optimally and legally.
To my mind, there are "think of the children" arguments, and there are "think of the children" arguments.

One uses "think of the children" as an excuse to enact broader control over society. Witness kiddie porn being the argument against P2P and PGP, or trying to censor "satanic" or sexually explicit lyrics, or any of a litany of other such nonsense claims.

The other uses it to remind people that this shit actually, you know, affects the children.
