Your body doesn't store protein. Amino acid (or gluconeogenesis) demands which cannot be fulfilled by dietary intake (what you've recently eaten and/or is passing through your digestive tract) are satisfied by catabolizing existing body tissues: skeletal muscle, and eventually, organs.

Over time, this adds up. Sarcopenia is age-related muscle loss, which amounts to 0.5%-1% of muscle mass per year. It's reversible through strength training and proper nutrition.

While this doesn't require eating hundreds of grams of protein per day (though strength athletes may eat, and benefit from, such quantities), ensuring that your protein intake is spread throughout the day is helpful.

Rice is interesting in that, while a carbohydrate, the insulin response to it differs from that of wheat and sugar. That and total dietary intake largely account for the lower prevalence of obesity among traditional Asian diets.

The Standard American Diet has a lot to condemn it. While it can be high in protein, it's generally higher in processed carbs, trans fats, and questionably raised and prepared proteins (CAFO / feedlot / factory-raised meats, with beef highly treated with hormones and antibiotics).

Among the fitness geeks I know, the first response to those looking to drop fat is to vastly increase the intake of green/colored/leafy/cruciferous vegetables. Just sayin'.

Protein intake? 0.5g - 1.25g per pound lean body mass, for general public through advanced strength/cardio athlete. The catabolic effects of long-duration cardio may require more protein even than strength training, ironically.
This reminds me of Zappa.js (http://zappajs.org/), one of my favorite CoffeeScript implementations of a web server on Node (although it's mostly just a wrapper for express). I'd be curious, though what advantages there are in creating a totally new web server (this approach) from Zappa's backwards compatible with Express.js's approach.
All the other manufacturers are worse. Apple is just the only one who publishes reports about it, and so for some reason they get pilloried for it. Apple does seem to take it more seriously than anyone else in the industry. If anything, they should be commended for their level of transparency and their continued, explicit efforts to improve things.
MIT still hasn't figured out a great way to teach physics, I'd look at this as another attempt.

Currently MIT offers 4 classes that count for the 8.01 (mechanics) requirement: 8.012, 8.01, 8.01L, or 8.011

Before they even place you in a class, they have you take an analytical exam to determine which class is recommended. This happens during orientation before classes begin, and it's the first of many things MIT does to help you pass the 8.01 requirement.

8.011 is the easiest, but they don't let you take it unless you've already failed one of the other subjects.

8.01 and 8.01L cover the same content, but 8.01L offers an extra month to go over that content. If you try and pass 8.01, but end up with a D (non-passing), they'll let you switch to 8.01L for the extra month.

8.01 is also a TEAL class, which is specially structured (and costs a lot of professor time) to encourage students to work together, and offers time in class to individually work on examples (as opposed to just listening to a professor).

The amount of effort MIT puts in to getting kids to pass the 8.01 requirement on their first try is exceptional. But with all their attempts, many still need to take 8.011.

I don't have numbers, but I'd guess that MIT spends more money teaching students mechanics than any other single graduation requirement. That probably made it a good guinea pig for this course, being that it's focused on education research.
very true, especially since node is single threaded, you might block other requests etc.
New startup aims to satisfy all of an average person’s basic needs
No, he's talking about a different DNS - OpenDNS. It's a confusing thread - the top comment is by a guy running OpenDNS. OpenDNS is a DNS service which resolves typos, blocks typo fishers, and sends empty pages to an OpenDNS ad page. They also have a bunch of options and controls, letting you block some sites (useful for employers, schools, and parents).

It sounds kind of sleazy (redirecting "no record" to an ad seems a little off to me), but the guys running it are apparently not. The prejudice against redirects to ad pages is more a result of ISPs who take your money and still give you ads, unlike OpenDNS which is free.
The source of this news is amusing - as they allude to in one sentence of the linked article, their own domain was siezed by US authorities for over a year, and eventually given back after legal wrangling.

Agreed, another problem with DC is the self imposed limit on population density in the inner circle. Buildings in DC must be less than 3/4 high as the the street is wide, or something like that? I don't know the exact rule. Then look across the river at Arlington, and how they smartly designed for urban growth, and you've got some taller buildings, mixed in with vibrant neighborhoods, and single family homes just a few blocks away form the skyscrapers. It really is a kinda nice.
Yes. I've come to the conclusion that chimps, gorillas and orangutangs (at least, maybe some monkeys, too) qualify as "human", or at least close enough. They need to be protected and allowed to prosper.
on the contrary, many open source projects sign and hash their packages, to anyone that verifies the signature and hash, the tampering will be immediately apparent.
Not only does there exist a bijective mapping between [1,2] and [1,4], there exists infinite different bijective mappings between a subset of [1,2] and [1,4].

i.e.: One could map bijectively from [1,1.5] to [1,4] and map bijectively from [1.5,2] to [1,4] (1)

To talk about there being "twice as much" in one uncountable infinity than in another uncountable infinity is nonsense, since you can't apply words like "twice", since the infinities can't be counted.

I don't have a successful product, but I have completed projects and even have a business meeting this Friday.

What I can say is do not learn. Focus on using people who already have technical knowledge. As a businessman you should not be in the business of learning technical skills as part of a development process.

I pretty much agree with you. I'm just worried that with all the comments about 'what is a number?', and 'sure, we can make infinity a well defined number', it will dilute the message of the article. Which is that infinity is not a 'number' (in the sense of real numbers). It's important to understand why it's not a number and what it means when we write it on one side of an equality.
You're forgetting about the network effect involved in scaling something like twitter which is commonly overlooked by people judging services like that.
It can be very hard to follow. That's why forcing yourself through modifying the hosts file (or a similar technique) could be necessary.
Hi, I'm the CTO for RAVN. When we decided to jump into the mobile dev game no one in our company had any experience with Object C or Android dev. We knew we wanted an iPhone app for sure, and probably an Android app eventually. I had taken a brief look at Objective C previously, and coming from Ruby/Rails, it looked less than trivial (memory management?! I hadn't done that in 10 years). I had heard about frameworks that would allow us to use JavaScript to write our app, and also allow for cross-platform development, so I started researching.

I looked at PhoneGap and Titanium primarily. We ended up going with Titanium for a few reasons:

- As you may or may not know, PhoneGap works by creating a sort of Safari "wrapper" that lets you write your app in HTML5 and JS. But the performance is crappy relative to native rendering. Titanium also used to work the same way, but more recently it actually compiles code written in JavaScript to native Obj C and Java. Clearly the benefit is speed.

- Even though Titanium only supports iOS and Android, we didn't really plan on ever developing for other platforms (e.g. Windows Phone, BlackBerry, webOS).

If you're looking into developing a mobile app, I would recommend taking a look at Titanium. To be fair, I had to write a little Obj C to hack geofencing functionality into Titanium (if you're interested in that: http://stevenou.com/post/17623116547/how-to-hack-geofencing-...).

There were lots of pros and cons to using Titanium and I'd be happy to answer any questions.
congrats Roy! Exciting stuff

They do mention that the lower depth results of the tree could be from bad entropy on a CSPRNG. Which is what I'm making my comment from. There may be a potential flaw in an implementation e.g CRT.

My comment was in regards to crypto usage in general where the most problematic factor is the misuse of PRNG and seeds. (ECDSA PS3 for example).

edit: Article makes points towards a flaw in the CSPRNG and Prime generation.
You clearly can't have 2i + 3 dollars, so by that logic, complex numbers aren't real numbers.
This is the only reason I clicked here. I too would love to hear more on that aspect.
What? Why? Hardware production has a much higher capital outlay than software production.

You'd be surprised at how much tools and equipment costs.
Did you ever consider appMobi?
Presumably it's a "single-page web app", where the HTML page is essentially empty except for JavaScript.

This JavaScript then performs the rendering by dynamically constructing an HTML page with the DOM, as well as fetching data from the back end, and so on.

It's a fairly common application model these days.

They probably use PhoneGap or something similar to glue into the mobile OS environment. (Edit: They use Titanium.)

My company is developing a very similar events app, also written entirely in JS (PhoneGap, Backbone, etc.). There are so many challenges in making it a smooth user experience comparable to a native app, but we've finally gotten there.

Oh these researchers don't understand PR (public relations). Here's an amusing way they could get one hundred fold the publicity that they're getting now without (technically) lying.

They cracked 12720 RSA keys. They could reveal the secret modulus in half the cases (6360 RSA keys) without giving away any indication of how they're doing it.

What they could have done is set up a website titled "RSA Cracker" which reveals one key every 3 minutes over a 2 week period.

At the end of 2 weeks, they could shut down the website without explanation.

Can you imagine the media frenzy that would ensue?

Where are you heading to from Melbourne? I doubt you could stay in Victoria and be more than 250km from a McDonalds.
We didn't specifically look at appMobi, but as far as I know Titanium is the only (relatively mature) framework that compiles to native Obj C, and is not just a wrapper for HTML5. The performance difference is enormous.
That would be a good thing, yeah. Maybe let me write these macros with javascript (which they could interpret on the server side) or any popular scripting language that fits the bill.
For him those may well be compelling reasons. Conversely, I'm not sure if it makes sense to get people to switch OS platforms when they are actually happy with what they are using now. It certainly doesn't hurt to stay informed about the capabilities of software you're not using currently (in some areas it should probably be mandatory), but switching in the absence of good personally-applicable advantages is simply not a reasonable cause of action for most people.
Or are you saying, "Ron Rivest was wrong, Whitfield Diffie was right" is still a horrible title?

Yes. That title made me think "ok, what famous argument dud they have which this is referring to?" (the way "Torvalds was wrong, Tanenbaum was right" would) and I can't think of any famous arguments about whether people have enough entropy in their prime generation.
Why can't we just put a computer in every lego piece with inputs and output on the "pegs" and holes, and have the pieces figure out on their own how they're put together? Then we just need a USB-to-lego adapter to export to the computer.

Judge: Paul Ceglia owes Facebook $76,000 and counting
I don't think I'm being clear. Sorry.

Obviously, if unrelated people around the world are at random times coming up with the same (ostensibly) random gigantic prime factors, there is a randomness issue.

The point the paper makes is that this isn't necessarily a CSPRNG issue. The issue is not necessarily that people are using rand() to generate primes. It's that to generate factors for RSA, you need more than a CSPRNG: you need a prime number generator that correctly uses the CSPRNG. The paper hypothesizes one very plausible prime number generator that would be insecure even if driven off hardware entropy.
Bad article, but the "you weren't invited" part is correct:

"Consider that the very hot IPO’, such as Facebook, are purchased by the underwriters before the public has even gotten a chance to get in. Underwriters are the big banks such as Goldman Sachs, Morgan Stanley, etc., and the shares they purchase go to their best clients first. This includes hedge funds, large institutions and huge money managers, not the majority of individual investors. "

"After the opening day, when the stock goes public and begins trading, most average investors can go in and buy shares at the trading price. But the opening day “pop” is over, and that is where the money is at, before the general public has had a chance."
(from http://finance.yahoo.com/news/facebook-ipo-etfs-180025693.ht... )

Unlike google's IPO which was a dutch auction, if the general public wants to make good money in facebook's IPO, they're out of luck.
It's worse than that. "Infinity" isn't even a single concept.

There are at least two distinguishable uses of infinity (there may be more, but I haven't figured them out yet, not that my opinion counts for much). There's the adjective "infinite" that refers to a property of sets. This is the type that Cantor studied, and it turns out to have many different types, which are pretty strictly ordered into layers. Then there's the noun "infinity" which is either a point or a location that points can exist at, and while it's usually possible for there to be several such infinities in several different directions, they don't come in layers. I believe Rider of Giraffes refers to these as "set-theoretic" and "geometric" infinities, respectively.

For the first definition, it's easy to distinguish between it and traditional numbers: an infinite set is bijective to a proper subset of itself. However, it's also useful to consider it a generalization of numbers, so you can count forever.

The second definition is more problematic. Here, infinity is just a point, just like all your other points. You can choose to add it to your set, or not. It usually behaves a little funny (like it makes certain operators not invertible), but you may have to get subtle to define it, or a set that contains it. Sometimes, it's not different than normal points at all, and sometimes it depends on the context. For example, if you take the real line and add +/-infinity, in topology you just get a closed interval like [0,1], whereas in analysis based on metric spaces you get something outright broken (fails to satisfy the axioms of the objects being studied).
I've pretty much given up on experiments like this. There are just too many variables to control for; maybe you're sleeping poorly because you're stressed out rather than because of the Vitamin D pill you happened to take today. I've used a Zeo and can draw conclusions between what the chart shows and how I feel, but I haven't been able to do anything to control what the chart looks like.

Honestly, the deepest effect I've been able to determine through personal experimentation is that coffee contains some sort of stimulant. Anything else is too subtle for me to be confident about.
I guess I'm not too familiar with what happened, are there any "unbiased" overviews of the events? I doubt the feds would give any information period.

To an implementor, isn't one of the biggest differences between DH (super easy to implement) and RSA (considerably trickier) the difference between needing one prime number instead of two?

Anyways I take your point. The paper really doesn't have too much to do with the title.
Range sum is now O(1). While I accept this is an improvement, isn't it a little... pointless?
I can't find the source for the life of me, but I remember reading an article about 6 months back that declared basically "there is not a single square foot of land inside the continental USA that is considered 'silent' any longer".

In other words, no matter where you "go to get away" in the USA, you will never truly leave the buzz of the city.

"Most people seem to struggle with this fact when first introduced to calculus..."

When I took calculus in college, I _did not_ struggle with this idea, despite at that time not having had any deeper background in advanced mathematics. Intuitively, the idea that you _approach_ some absolute as you edge the denominator ever larger made perfect sense to me.

Formally, my instructor made it clear that the _limit_ as you approach something was, in nature, different from any particular fixed value (of x). So, in a clearly defined manner, as you _apply the limit operator_ to the left side of the equation, the right side correspondingly behaves differently.

This concept never troubled me. As other comments here imply, this is an idiom specific to (differential) calculus. The only caveat might be in the use of strict equality, since limit operations by definition indicate asymptotic behavior. One could argue that a different type of relation is described (such as 'approximately equal': ≈). But then it's not infinity itself which is at issue.
Perhaps it doesn't work for companies and bureaucracies, but it works fantastically well for me, with a lil light music and warm lighting in the background, a blank sheet of paper (unlined) and an ink pen.
