Yes, social changes could produce dramatic changes. But social changes themselves are usually very slow, and I know of few exceptions to this in the context of health. Normally people blame obesity on social aspects (like exercise) which 1) have changed very gradually and 2) don't matter anyways (explaining that would make this a much longer discussion). If someone could come up with an example of just 1 social change that dramatically shifted in 1980 I would be very open to the idea. The only thing I know of is weight-training- the obesity numbers used are normally just based on BMI- they don't take into account that muscle isn't fat.

Here are some actual numbers:
http://en.wikipedia.org/wiki/File:USObesityRate1960-2004.gif
What we see is a linear increase starting around 1980, where before then rates appeared to be constant.

Before 1980, 1/3 of Americans were overweight. Every overweight person has the same metabolic problem as the obese, just to a lesser extent. The fact that 1/3 of Americans are now obese 20 years later is what I would expect due to a gradual decline of American health that hit a tipping point for obesity around 1980.
It's a step, alright, but how do you know that it's a step in the right direction? RepRap has not set very much of world on fire yet. When I can do more than print out more than a low-res plastic coathook, I'll get excited. How many years will it be before I can replace my car's crappy plastic door panel with a high-quality printed one? Will it ever happen? It doesn't seem like this will happen soon enough for me to hold out on buying a new car.
Mockup previews of Appleseed 1.0, feedback appreciated.
very cool product, although I wonder opening up publicly for free, how much bill will twillio charge you?
oh definitely, for the right person college can be hugely valuable. However that is not every person and that's my complaint. There seems to be the idea floating around that every person will benefit from college, at least enough to offset the cost of it, this isn't true.

Every person is different.
I've gotten some criticism that Appleseed's design and user experience was lacking, so I decided to work on a set of mockups for where I'd like to see Appleseed go for a 1.0 release. While we're still on version 0.7.9 (publicly), I usually feel that solid mockups can set good guidelines for building software for the future.

I would love to hear HN's thoughts on these, I'll be taking criticism to heart as I break these out into HTML over the next few weeks.
great post, I remember last year I interviewed with Flixster and they joked with me that who programs in JavaScript anymore, we all just use jQuery and don't need to write raw JavaScript.
No, that's just the generation process you are referring to. The really interesting thing is moving them around like currency. The idea is that they can replace dollars, not that they are just empty computation.

I am not aware of anyone selling home users idle clock cycles. This is probably because it doesn't work economically. The difference between a home desktop on 24/7 doing 'nothing' and on 24/7 doing its maximum compute load could be in the low tens of dollars of electricity per month for the user, so to actually sell the cycles you're going to have to not just charge that much, you're going to have to remit that much to the home user, plus extra for wear and tear. (Or hope for dumb users.) And then you have the problem that this cluster has low bandwidth and high heterogeneity, so pretty much the only thing you can sell it for is something like Seti where you have relatively small amounts of data that you want to run enormous computations on. In the end I just don't see how you can compete with Amazon.
IANAL, but I don't see how that kind of law can pass the three step test of the TRIPs treaty. Copying movies for personal use clearly conflicts with "a normal exploitation of the work".

Then again getting EU countries to stop subsidizing their farmers will probably take decades, so this sort of violation is probably pretty far down the list. I'm not saying I agree with the current IP, but it's highly doubtful that acts violating international treaties are "legal" in the strictest sense.
Yes, they do and they did. Nitish Kumar, the Chief Minister of Bihar(a backward state), was reelected with absolutely majority due to his honest and dedicated efforts during his 1st 5 year tenure. Poor/Rich, people of all castes/religions, voted unanimously for him and his good work.
I'd really love a version of the iOS YouTube app that would let me limit it to specific users and/or playlists I've created.

ioerror is Jacob Appelbaum's handle on twitter too.

I don't know anything about the site that the article is on, but it corresponds pretty closely to what I've read elsewhere.

I suppose a lot of folks probably do consider this type of extralegal harassment to be a political left/right issue. Personally I don't understand that type of thinking and suspect it's probably not useful to attempt to reason about that degree of madness.

I do believe that a lot of politicians and prominent officials are earning their place in the history books...right next to Sen Joe McCarthy in the article on 'Un-American Douchebags'.

Right you are, but Alfie based this almost directly on CI. You recoded some of it, but the initial purpose and feeling of the class remains as essentially a copy of the CodeIniter Helpers. The sort of thing that is so similar it was just easier to call a port. :)

Is pip install that hard? Surely any deployed project is already managing a requirements.txt/buildout/setup.py/etc.

The C speedup extension for simplejson existed well before it was merged into Python stdlib as "json". Are you so sure you'll eventually get said improvement?
The Smartest Person Project
So there we were, having dinner, embroiled in conversation. "Who is the smartest person you know?", he asks. After an indepth conversation about intelligence and the different meanings of the word, we wondered: "What would happen if we asked everyone we knew to identify the smartest person they know, then asked the next set of people and so-on...."? Well - that is what we are doing: www.thesmartestpersonproject.com
YES :|
Very interesting. I had a similar (same?) idea though did not push it further than grabbing the domain (ovrdub.com)

UX-wise, I wonder if there is a reason why you do not represent the different "pieces" as tracks ? I think this might make it for a simpler user experience ?

I'd be definitely interested to peek at the code.
Completely getting your point that it could be annoying for some people out there. It never bothered me though and while this is not really a strong argument, it's always one of the first things to come up when people talk about PHP's flaws.

If it really bugs you it could easily be solved with a few helper/wrapper functions.

(Besides that, regarding elegance of syntax, there's no doubt that most other languages used for web dev'ing are lightyears ahead of PHP.)
May you give me more descriptive information on the event that you are talking about? Is there a website that I could check out?
Nah. I think he's saying that if you like the way he does things, come on in, if not, please just go away.
I can't tell you how excited I am in anticipation of Ron Paul news appearing on the front page of HN.
They're going to start using PHP 5 features, but that won't remove the large amount of PHP 4 code they already have. Neither will it remove the vast body of plugins/themes from play, most of which are updated quite sporadically.

If there's anything that will cause internal architectural changes, it's the project's general focus on new features over any other goal.
It wasn't pre-ordained that Joe McCarthy would go down in history as an un-american douchebag. He had a great ride at the top with lots of good americans saying good things about him for a while.

If noone called him out, he'd have just been another politician making hay out of fear and "the other".
Another example of the issues faced by a private currency were related by Krugman in 1998. It describes the economic issues of a Capitol Hill baby-siting club that issued a limited amount of scrip to keep track of hours of time for people offering and using baby sitting services:

It's a good description of an unexpected problem.

> No, of course not. I was being metaphorical.

Also, patronizing. And quite possibly mistaken. I mean, how do you know what was in US flour in 1914? It was legal to mix it with chalk dust and cornstarch not very far before that, and I think it still was in 1914: http://query.nytimes.com/gst/abstract.html?res=F20810FB3D5C1...

http://www.rsc.org/education/eic/issues/2005mar/thefightagai... claims:

To whiten bread, for example, bakers sometimes added
alum (…) and chalk to the flour, while mashed potatoes,
plaster of Paris (calcium sulphate), pipe clay and even
sawdust could be added to increase the weight of their
loaves. Rye flour or dried powdered beans could be used
to replace wheat flour and the sour taste of stale flour
could be disguised with ammonium carbonate.

Anyway, so at the time, I think there were already a lot of food additives in use. They just weren't systematically vetted for toxicity the way they are today.

> However, yesterday when I opened a box of flour that I'd ordered from the internet, I realised that it made me feel kinda snobby. Why do I order flour off the internet? Protein content. Read this:

Thank you! That was awesome! I had no idea.

> carboxymethyl cellulose, carageenan, guar gum, xanthan gum, agar, pectin or maltodextrin.

It's true that those are common additives, and as you say that they are generally not unhealthy (those are all fiber, protein, or a mixture of the two, aren't they? Except maltodextrin, which is a starch), but they are usually a tiny fraction of the food.

> Real, good food that is made the proper way doesn't need to be thickened, bulked up or stabilized.

I don't agree. I use cornstarch, arrowroot, or even white flour as bulking and thickening agents when I make real, good food the proper way, and I often use milk, mustard, or egg as stabilizers. I've used lemon peel as a stabilizer too when I made blackberry jam, because it contains pectin. I don't know how you propose we should make blackberry jam without adding stabilizers?

I don't know of any reason to believe that the more popular food additives you list are any more dangerous than the traditional ones I usually use. I just don't happen to have them in my pantry or have experience cooking with them. (Indeed, many traditional additives like sassafras and lead sugar have been discovered to be toxic in the last couple of centuries, but to my knowledge, there still hasn't been a systematic testing program.)

I recognize that you're probably a lot more experienced at cooking than I am, so maybe I'm totally off the wall here. Enlighten me!
What a terrible way to achieve network concurrency. You can't possibly think that each upload is using a "core" (as described in the article). That would imply that a two core web server could only serve two files at the same time. Sending a block of data from one file descriptor to another is not a CPU intensive task.

Just use twisted or similar and run as many as you want concurrently with a single thread.
This is some Douglas Rushkoff style stuff.
Way to go! Those mockups look amazing- They're clearly Facebook inspired, but it brings it's own flavor to the party.

Did you make these in Photoshop, or HTML? Did you do these yourself, or have these made up?

Either way, FANTASTIC work.
How PC People Keep Making Apple New iPad Customers
If my junior high and high school curriculum didn't even make it through precalculus after the typical six years of dedicated math courses, often featuring nightly homework, I would probably wretch at the mention of math too.

I suspect that your students had already learned that they weren't going to use the covered material, even within subsequent math classes -- by being taught the same material year after year.

>Producing "rigorous" epsilon-delta proofs (and whatever else we did) was a tedious exercise which improved my abilities in no significant way

And you want to blame that on the course itself? This is exactly the problem with education--kids feel like its the teachers responsibility to force them to get something out of it. It is your responsibility, no one else's.

Furthermore, I took analysis in college and I gained a great deal from it. It made me a much more precise thinker, mathematically and otherwise. Your lack of growth from the course is no ones fault but your own.

Edit: thinking about the issue a little bit more I realize that its not as clear cut as its "your fault". There is a big problem with how math is taught, especially at the younger grades. My issue with your blaming the course and the teacher for your lack of growth is that once you're at the college level you shouldn't need the teacher to do a song and dance to keep your attention. You're supposedly there for one reason only, to further your own education. Thus the responsibility is on you to get as much as you can out of every course. If the content of the course didn't match your expectations then the problem lies elsewhere, not in the material or how it was taught.
The mockups look great.

Gut reaction is that you are clearly inspired by Facebook, but there's only so many ways to peel this particular orange. I'd consider a primary color change as a quick and painless way to distance the two; I think it's the blue that's keying me to Facebook the most. There's an argument about whether that's fair, that they psychologically own social blue in my mind, but better to differentiate (in my mind).
Thank you very much! There is definitely some Facebook influence, I tried to take the best from the best, so you'll see some Gmail in there, some Livejournal, and some Facebook, along with a little bit of others. No MySpace, though. :)

I did these myself, I'm not a designer instinctively, but I had a vision for how I saw things working, so I just started hacking away and refining things until I found something I liked.

And I did them in Photoshop, that's how I usually do web design, since it's what I'm most comfortable in.
This is a filtering/sorting problem. There is a lot of people and companies working on this. It is good having something to be filtered/sorted
there's only so many ways to peel this particular orange.

It's true, there's certain paradigms that just work, and I played around quite a bit with more experimental approaches, and I just couldn't see the user flow working in a way that didn't throw users completely for a loop.

I'd consider a color change as a quick and painless way to distance the two.

With the beauty of Appleseed themes and CSS, I'll probably try and have three or four variations on this layout for the 1.0 release.

They gain the effect it is having on other people. For every one of us that gets enraged at this sort of bullshit, there's 9 more that are terrified to speak out after seeing this. The problem with America is that unless we personally are being injured we see terrible things happening and just shrug and go on with our latte-sipping, BMW-driving lives. Our freedoms are slowly being eroded and no one really cares as long as they can keep watching TV and driving their fat asses to McDonalds every day. It's like the toad in the pot with the water getting hotter ever-so-slowly...
What concerns me is the emphasis on open-source and decentralization on the front page. They are marketing the features like this is a software product, which is not how one should market a social network.

If they ever want this to appeal to anyone but alpha-geeks, they should emphasize how the unique features make the _experience_ on Appleseed better than it is on Facebook/other networks.

I work for a company that grinds railroads. While 100% of the office employees spend more than half their time in front of a computer, none of the people in the shop do.

So, I'd say it's most certainly an overstatement. I'm not willing to exclude the large sections of the American workforce who still work in industrial production.
One related question that I was just thinking about this weekend was if people have similar purchasing habits for toddler/child apps compared to apps for themselves.
But this "war" on terror is an excuse for the government to continue to grant themselves "emergency" powers and give their friends in the defense industry hundreds of billions of dollars.

Kind of late to be asking, isn't it? I'm doing an internship at Facebook, and I'm reasonably sure they've finished hiring interns (about 300 of 'em).
Great approach, and kudos to you for going this route! It's a very clean look, and a great base to build on.
I would add the additional thing that if you have a big green button and a big red button, the toddler is not going to have the same good/bad stop/go associations with those colours. A big red 'exit the app and go spend money' button is going to get pushed just as much as the 'go back to the game green button'.

From the article:

"Finally, here are some gripes with iOS:

•Home button needs an off switch. I need some way to disable the home button or make it harder to access during app play, e.g. a triple click or some other morse code sequence.

•Need a way to hide videos. Eli knows how to get to the videos. He can find the icon no matter where I put it. I can disable videos through restrictions, but that doesn't really solve the problem. I would really like to be able to hide this icon like you can do for system icons on Windows. Another option would be to put the restriction on the icon itself and force me to enter the password when clicking on it. Come to think of it, this would work for the home button too.
"

I very much disagree with the first point. It makes your app a 'trap' that even an adult might not be able to figure out how to exit from. This is a stunningly, spectacularly bad idea and violates the whole "the user is in control" illusion. If the easiest way to exit your app is to reboot the machine ... then your app blows, and you suck.

If the kid is pressing the home button a lot, and this annoys you, then you have to think about your goals. Toddlers like to bounce from one thing to another a lot, and they love to be in control (because they have so little control of everything else in their lives).

We think of toddlers having short attention spans, but sometimes the converse is true, toddlers can also have amazingly long attention spans - the classic example being the kid who sits there and bangs a pot with a wooden spoon for endless hours.

If the toddler is exiting too often from the app, maybe the problem is not with the home button, maybe your app is just not engaging enough.

I saw (for instance) one toddler who could spend hours making the angry birds fly the wrong way. When they do they make indignant squawks, and he loved that. Without fail any adult who watched him doing that would quickly become bored and try to show him how to 'do it right'.

With respect to the videos, I'm not sure what the problem is, is it bandwidth? Is it easy access to age inappropriate content?
Piecing together the documentation can certainly be painful, especially if you are doing things that don't mesh with the norm (for example last time I was refreshing myself on enlive the tutorials for that had switched to mustache, while I prefer compojure) making things entertaining until you get back into the groove.

However for me I love the power that comes with the fact I can piece together the parts I want easily after some initial experimentation, as they are all built to be independent of each other. Makes the workflow more fluid.

Though if I were to even want more of an "all in one box" solution I would be more prone to use Scala + Lift right now.

This is a common concern, and I understand where it comes from, but I actually disagree that we should be marketing directly to users

Instead, I think the most important thing is to become the de facto foundational software for anyone who wants to build a social networking site.

Do you want to set up a social network just for cat owners? How about one for orchestra students around the world? Or a fan club of the Anime series, Cowboy Bebop? Then we want you to run Appleseed. It being open source is a huge benefit for that. And the distributed features are gravy. Or icing. Depending on your tastes.

Users may not ever know what Appleseed is, and that's fine.

In other words, Appleseed isn't the next big thing, but we want the next big thing (or things) to be built using Appleseed.
We had a strange bug that only surfaced on the last day of every month. One of our directors asked what we were doing to troubleshoot this bug. I responded that we were a bit more focused on troubleshooting bugs which occurred every day.
