What would be the price tag for the construction of one of these datacenters? Also, how much more expensive (in operating costs) is a, say, 1.1 PUE datacenter compared to a 1.07 PUE?
Hey, sorry, one more time. The updated link is also wrong, it's relative to your blog rather than absolute i.e. http://technocalifornia.blogspot.com/2011/04/research.yahoo.... as opposed to http://research.yahoo.com/files/recsys2010_submission_150.pd...
In terms of GI, the Glycemic Index, sure they are. However, the more important measure it GL, the Glycemic Load, which is basically the GI multiplied with the average amount.

For example, even though a cherry has much higher GI than a potato, you eat more sugar/carbohydrates in one potato than in one cherry, so a potato has higher GL and thus higher insulin response.
Most of the classes on there have lecture notes, videos, assignments, and projects. They basically have the entire participating classes online. If there was an educational medium that combined all of the OpenCourseware's with other free online educational content providers like Khan Academy, it could be really helpful.

What a good idea that I would not have thought of. Thank you!
I think you've got the math backwards -- the native capacity is 38.4 TB per unit. If your data is compressable, you can store roughly 2X the amount of data in the same physical space, which is how they come up with the 76.8 TB figure.
Does the CDD disallow using a non-Google search engine? A quick perusal of the latest CDD suggests that isn't the case.

My understanding is that you have to use Google's search engine if you want to slap "with Google" on the back of your phone.
If I recall correctly, Taubes discusses that ~1914 was a historic low point of meat consumption because the supply could not keep up with all of the demand from the increased immigration. So 1914 is certainly not a good baseline either.

I don't think it is at all fair to say "they were already using white flour..". Much bread had very different qualities back then- more likely to be slow fermented instead of quick rise, much more likely to be local, etc.

I think this misses the point anyways- the quality of food was different- you see a large increase in sweeteners in the graph, oils transitioned away from natural animal fats to industrial processed seed oils- and in general food became much more processed.

I always thought "open source" meant that I, the user, got access to the source code, and I was able to make changes and share them. I don't like seeing the meaning of open source progressively reduced to nothing. We already have a category for "corporate manufacturing partners can pay to access the source" - that's proprietary software. It's not OK to use openness just as a marketing term and claim that a product being distributed now is still open just because the source will be released at some unspecified time in the future.

So you say that it is amazing but the "fanbois" are somehow wrong in finding it amazing? I have trouble understanding that.

I'm not aware of any widespread denial of the existance of tablet PCs by "fanbois", I remember them quite enjoying mocking those tablet PCs, especially by contrasting them with the iPad. Longer battery life, thinner, lighter, no keyboard, running no desktop OS, you can get one for $500 – all those features together are a genuine innovation and they touch on both hardware and software. That doesn't mean that some or all of those individual components didn't exist in other products often long prior to the iPad.

You can't build the iPad without knowing what you do. Just look at how Apple's competitors are still struggling. If making a tablet people want to buy was just a question of taking existing technology and marketing it right there would have been credible iPad competitors much earlier.

Hey, pg ... does that include our application by any chance?

I realize you don't have to answer this, but I am just curious:

It seems on the surface that our company is much closer to what you say YC is looking for, than many companies you had in W10, S10, etc. Let me just illustrate a couple points:

1. You emphasize resilience: we got rejected by YC in the past and went ahead and raised funding, launched and already have 70k (and counting) users since 3 months ago. The vast majority of our reviews are 5 stars.

2. You care about companies with huge potential. We're building a next-generation, distributed social network which gives users control over their data, and helps their social lives in the real world instead of online.

3. You want to see founders who did extraordinary things: I went to college at 14, played in Carnegie hall when I was 7 years old. (http://magarshak.com/piano) My co founder can father a small child just by looking at a woman... (http://www.xtranormal.com/watch/7203877/fundraising)

4. You care about a capable team that has been together for a long time: http://qbix.com/about . We have made websites such as this: http://blurts.com which is now worth over $5 mil.

etc.

So I am curious why YC didn't even want to interview us, but then again, your rejection letter doesn't leave many clues :)
I had a business acquaintance get her feelings hurt because I didn't follow her back when she followed me on Twitter. I looked at her feed and she literally had tweeted about her breakfast that morning.

If you look at the chart and treat the blue (sweeteners) and purple (fats and oils) streaks as a single one, together they increase 1.6 times from around 25% in 1914 to 40% in 2004. That's a huge increase! In fact, these two calorie sources are the only ones that consistently increased over the given period. I am surprised anyone is even talking about grains and meat.
One week after april fools, I'll wait until this gets picked up by more reliable sources.
Yeah. Would it have killed 'em to at least build a working prototype before sending out the press release?

Even if the claims they're making do turn out to be true, it could still suck in any number of other ways. How durable is this engine? Is it still gonna be running after a hundred thousand miles?
Yeah. In this app I used the (very nice) ShownDown.js as a MarkDown format generator. Which DOES properly sanitize most input. I then added the special <script> evaluation stuff as a cool "hack".

As client-side JavaScript gets more mature, I do expect there to be more frameworks that will just "do the right thing" for developers who write code like this.

Writing Maintainable Event-Driven Code
I fear the following will sound rather negative. If you're only looking for positive suggestions, please skip over this. I know you mean well and I wish I could offer you more encouragement. Hopefully others are able to do so.

I'm writing this with more than ten years of experience providing international response search and rescue services. We got started after getting frustrated by our inability to get obviously needed supplies into disaster zones. It turned out to be easier to provide services. Along the way we learned a lot about the road blocks and solutions.

I've seen warehouses full of supplies from the US donated by well meaning charities. Thousands of people donated clothing, packaged it up, shipped it out, and expected to make a difference. But there it sat, rotting in the heat and humidity. The intended recipients thought "those damned stupid Americans, sending us stuff we don't need." The donors thought "those lazy recipients, not putting our goodwill to use."

There are valid reasons why the Red Cross and other agencies say "Just send money." Just because a disaster has occurred doesn't mean that customs inspections stop, or taxes aren't collected.

A clip about one mayor's village doesn't accurately portray the entire picture, including what is already in the pipeline, if they'll still be there the next week, and the logistical problems of getting anything there.

You can send money in seconds. Supplies take days, or weeks, and these situations are very fluid. Send the money and it can adapt to the current situation. Send supplies and they'll rot, and possibly clog the network, if the situation has changed.

Getting "the stuff" from here to the port in Japan doesn't take care of all the distribution past that point. For starters, someone needs to break down your containers into smaller packages and route them via whatever means are available to their intended destination. (And those means are already shipping other things.)

And someone needs to track what is still needed, what has arrived, what is in transit, etc.

There are a lot of very complex pieces to the puzzle. The Red Cross and the other agencies know how to fit them together relatively well. Let them continue to do so rather than reinventing the tools, processes, and relationships they've already developed over many years.
Because most people don't expect a ton of traffic, and generating every page dynamically works until they're surprised to have hundreds of visitors in a short period of time.
Sorry for not being clear. <:)

I agree that people should donate clothes they no longer need or want. I was referencing the documentary about Africa as an example of just how far the benefit of donated clothes can reach.

As a foreign student you are allowed to have equity in the company as long as you are not employed by that company. You are legally allowed to own a company as a foreigner, just not to work there. So the myth about you not being able to own equity is b/s.

Honestly, just start your startup, go as hard as hell at it, make money, get funded by a renowed VC firm and if they think you are useful, then they will sponsor you as their employee and you will be legally employed in this country.

Another route is to make so much money that you are given a green card. I believe if you generate more than $1 mil. in rev. and employ 12 citizens (any restaurant can do that), then you'll be all set.

You will not break laws regarding employment by monetizing on the app.

In cases like this, is there any commercial hardware-accelerated compression tech which would make a useful difference? Not just tape drive hardware, something more clever.

I know the latest WinZIP can losslessly recompress JPGs by fudging with the compression algorithm, for example.

Or what about deduplication? Is there any deduplication tech which works on image visual similarity instead of file block matching?
Maybe your app could be the launching point for one of those frameworks as well, it might be a nice value added feature.
From the article: "...the grain figure doesn't even include the two hundred pounds of potatoes Americans ate every year in the early 20th century."

Table 4 of the original report gives more detailed numbers. In the period 1909-1919, grains, potatoes and sweeteners together contributed 54.4% of American calories. In 2004, it was down to 43%.

On the other hand, fat consumption nearly doubled over that period (from 12.6% to 23.9%).

Mark Boulton's posts really are some of the best typography eye-openers. Especially his "Five Steps" posts[1][2] were what got me into design and made me "get" it. And it didn't take a lot of time to read through them. I recommend that people skip his book and read these two pieces instead.

Bear in mind that the grid guide is more of an intro piece; you probably won't be able to create grid-based websites after reading it (I know I wasn't).

Another good resource is Typography for Lawyers[3]. I'm actually very surprised (and disappointed!) that Paul didn't mention it. It's recently undergone a redesign, which has rendered all its former links broken, and it seems a little harder to navigate and browse for fun, but you must flip through the digital pages. It's probably the best typography resource for newcomers along with Boulton's 5-step guides.

I also just combed through my bookmarks to see if Boulton had anything else, and a great presentation popped up[4]. It, too, is great to get you into the typographic mindset.

These are really the best way to get someone into typography, and they are quick to read; no resounding THUMP from dumping seemingly insurmountable literature on your desk.

Of course, once you've got the bug, it'll never leave you, and a lot of the world will look a lot worse and be more painful for it. Educate yourself at your own risk.

True, but this wasn't made clear, so I felt the need to "debunk". "Ask your customers what they want" is a common startup catch phrase, and while it does apply in many situations, it isn't as clear-cut and true as many seem to think.

It belongs in the same bin as "execution is everything," "ideas are meaningless" and "you need a cofounder to succeed." Useful and oftentimes true, but by no means a universal truth.
FBI Releases Document Confirming Roswell UFO Incident?
"Last week, the prototype was presented to the energy division of the Advanced Research Projects Agency, which is backing the Michigan State University Engine Research Laboratory with $2.5 million in funding."

I am just as skeptical, but if this is how they get their funding to build that working prototype than I'd say it's fair enough.

One way might be with a closure that wraps the entire module though taking a more OO approach would probably be safer, such as initializing objects with the DB connection as an argument.
At the end of the post he did write "From a technical perspective, authentication defines who someone is and authorization defines what they have permission to do. However, I didn't find that terminology useful for my purposes here."
What's needed may just be to solicit a wide confidence interval (e.g. "this task will take between 20 minutes and 1 month, and I'm right 90% of the time recently when making such estimates"). You can drop the lower-bound part, probably.

People absolutely should be able to provide a rough estimated amount of effort for a task. The trouble is in using a single point to describe the whole probability distribution. You may be right, in that nobody seems to have a great way of soliciting a probability distribution (or even a single probability) that makes sense. Something like a 70% confidence interval bracketing the amount of effort would be useful, but not sufficient.

I also agree that even if people could describe their beliefs about the required effort rigorously, you have to wonder how much planning/analysis they should spend trying to come up with a tight estimate. An 'outside view' - http://wiki.lesswrong.com/wiki/Outside_view - could give something reasonable in cases that aren't too novel.

I think estimates will never become useless. It's just that we may decide to replace them with "time by which we'll be late only 1/6 of the time", and provide feedback and incentives for people to correct this estimate so that it's, for someone who's experienced in the domain, eventually relatively unbiased.
It's funny, the top Google result for [juxtaposition precedence] is exactly this question, posted on the PhysicsForum boards. 2 is actually leading 288 by a hair there.

http://www.physicsforums.com/showthread.php?p=3235154

Anyway, the answer depends completely on whether you believe that multiplication by juxtaposition has the same precedence as multiplication by explicit symbol. There're good reasons to believe it doesn't, eg. the first post on that linked thread, but whatever the answer, it's entirely based on typographical convention. I don't work in the community that cares, so I don't really have an opinion, other than to point out it's not as cut-and-dried as virtually ever poster here believes.

In the community that I do work, people who write parsers, things like this have to be explicitly specified. That's why I maintain that the correct answer is "syntax error".
Thanks for the information!

Actual effort to complete can be quite surprising, but effort spent per day also varies tremendously. For example, when things are going well, there may be a burst of joyful effort.
Some of the storm scenes in Jurassic Park are from a real hurricane that made landfall in the last day or so before they were scheduled to leave Hawaii. The site below is the best online resource I could find and it leaves out a lot of critical details (that I remember from a show on The Weather Channel). IIRC, one person (probably the person referred to below as Kennedy) got out of Hawaii via space available with the military and then airlifted supplies in to give relief to the Hawaiian people, in part so they could get the cast and crew out who otherwise would have been stranded there for god-knows-how-long. There were no commercial flights in or out and no permission to do anything of the sort. The plane was only allowed to land because it carried relief supplies. Once empty, it was okay to fill it back up and fly home. There were a number of ways in which the film crew provided relief locally (to the hotel they stayed in and surrounding areas) while still on the ground because of the expertise and equipment they had. It's really a very inspiring story which I think should get more press.

So just keep trying. You don't know what you can do until you try.

Best of luck.

Kennedy jogged two miles to the airport to explore their options.

"The destruction in the airport was unbelievable," she recalls. "All the windows were blown out in the terminals, and the buildings were full of palms, trees, sand and water. Every single helicopter had been tipped on its side."

Thanks to her relentless efforts among airport and military personnel in Lihue, Kennedy was able to hitch a ride to Honolulu on a Salvation Army plane and began organizing from a pay phone. Over the next 24 hours, she not only coordinated the safe return of the company, but also arranged for more than 20,000 pounds of relief supplies to be transported from Honolulu and Los Angeles into Kauai.
Very cool stuff. Also that library looks pretty sweet. I'll keep it in mind if I ever find myself needing something like it. Congrats!

Yes, why not? One reason may be prestige. As he explains in the paragraph "publish or perish" he would hire an applicant who published 1 article in Nature or Science as opposed to an applicant who has 100 papers in the arxiv but nothing published in the "prestigious" journals. It is interesting that he does not claim to read the articles and evaluate their merits on content; academia is all about prestige.
