I am curious how polyphasic sleep preferentially affects consolidation of declarative or procedural memory. (That is: does it improve procedural memory, affected by REM sleep, at the expense of declarative memory, consolidated by SWS?)
I don't get how hard this is for people to logically grasp. Scientific conjecture doesn't logically hold water until we stop assuming that X->Y and actually empirically show or mathematically demonstrate that X->Y.

In physics we have equations like E=mc^2 which are constantly tested and validated. In chemistry we have repeated and empirically validated experiments that show how adding a catalyst to a reaction will speed it up. In biology we have demonstrated and visible results of how different types of light affect plant growth. In electronics we repeatedly validate that V indeed equals I times R. And the list goes on...

Don't you get it? X process is repeatedly tested and validated to produce Y results. That's how quality science works.

I don't care if you have a whole mountain of what you claim is Y "evidence", if you can't repeatedly demonstrate and validate the assertion that X process produces Y results then it doesn't matter how much "evidence" there is, there is no true logical basis to claim that Y infers an X until you have demonstrated X->Y.

Pardon my skepticism.
Those are all excellent questions. Unfortunately I don't have all of the answers. I know he test marketed the changes and that it failed -- it never made it to a full national roll-out. The way he tells the story is that he tried improving the quality of the food and promoted it on the package but kept all other variables equal (most notably price) and it was met with disgruntled customers and sales suffered. I guess I can say that this was a prepared meal product -- Ultimately what worked was sticking with the low quality ingredients, including more of them and ditching the veggies. In the end he did turn the brand around with this strategy.
This is a good example of why you need to think twice about getting investors. The guy suing him was actually the founder of Tesla, the Musk dude was just an early investor who hijacked the company and threw out the founder over an engineering disagreement.
there's value to be had in both types of community. anonymous ones will have more participation and broader ranging appeal and subject matter, registered/profile communities with enforced social restrictions and reputations will be much more friendly for the mainstream troll-hate crowd
Probably correct, but I bet you a nickel that the expenses of useless bureaucrats are a miniscule fraction of capex and opex.

A different story ranking algorithm idea: You can't vote stories at all. A story's count is determined by the sum of the comments made.
There are things to be learned from the article at more levels than just the design of new protocols. For example, I would say this good advice that applies to ordinary smart people:

"Do NOT store users' passwords. Do NOT hash them with MD5. Use a real key derivation algorithm. PBKDF2 is the most official standard; but scrypt is stronger.
Please keep in mind that even if YOUR application isn't particularly sensitive, your users are probably re-using passwords which they have used on other, more sensitive, websites -- so if you screw up how you store your users' passwords, you might end up doing them a lot of harm."

So you have gone to the trouble of employing an extremely rigid sleep structure that requires a lot of self-control to maintain in order to gain back some productive time, but you reduce it's efficiency by 1.5 to 2 hours each week so that you can drink 3-4 nights a week? :)
the Musk dude was just an early investor who hijacked the company

didn't he hijack paypal, too?
The point I was trying to make is that the customer didn't want "better," they wanted the "same" even though it was crappy. The post I responded to seemed to want an example of that.

On your points, I agree mostly but in this case people didn't want better quality. They liked the taste of the lower quality product.
that is awesome. For sale?
I think if you can sleep for more than half of a day you've definitely got some sleep debt going. Do you use caffeine at all? That may account for some of your other symptoms.
You worked there? Interesting. They're still up, right?

Our goal when we started the project was to be, in a way, the opposite of groupcard. Whereas they (and their format, and their examples, etc) encourage quick, short messages ("Happy b-day dude! 21, wow! now you can legally drink!"), we created our site for people who want to write longer, more personal, and more detailed letters. Hence the design with the scroll, the hand-written fonts, the lack of shinny images, etc.

You'd be surprised, but the average length of the letters that are being submitted is a bit over 300 WORDS...

I do like groupcard... we're just targeting a different audience/need...
You'd better believe it!

I feel I should mention that the time I am awake with this schedule I typically am 'rested' and very alert. I had issues adjusting to the 8-5 life because my body demands so much sleep natively. When I was getting 8-9 hours of continued sleep in one night I was waking up groggy and not really getting started until 1-2 in the afternoon. This cycle corrected it.

It's also not as rigid as you'd expect. I can move the start and end times of the nap/bedtime around approximately +/- 2 hours and still feel alright. Altho a nap starting at >7pm just feels 'weird.' It's the full skippage of a nap that wrecks shop.
Plot: built on the elegant combination of Ruby, XMPP, and Flex.
Can anyone explain:

"Client-server application security: Distribute the server's public RSA key with the client code, and do not use SSL."

It seems like the point of this is to make sure that when communication moves from the client, only the server with the proper private key can decrypt it - BUT, aren't you just going to use OpenSSL to implement this (via TLS)? Is there some other way to accomplish this I'm not aware of? What's he specifically warning us against?
...and I'm willing to bet that a classically trained violinist with a sufficiently large following would prove a very attractive target to trolls.

Are there really places on the internet you can "go to have health, civil debates" that are a) troll-free, and b) unmoderated? The world has neighborhoods, each one tnds to have its own police force.
I originally built this as a b-day present for my wife, and she liked it so much that I decided to turn it into a public service. And I'll be happy if it's just that.

But we do have a model to generate (modest) revenue, which hopefully will cover the (again, modest) costs: At the end, when the recipient has seen all the letters, s/he can order an actual, physical book with all the text. It's printed on-demand, and we're make a bit of $$$ over what the publisher charges.
I think that to some extent, the professor might be right. What if I was to take that same course, with the same professor, and got the same assignment.

I could easily browse his source code when I get coder's block.
That's the one. He was one of the founders.
You wrote it once, you can write it again (not exactly the same, of course, but you get the idea).

Can you? That code is now a trade secret for that company, and if you wrote a clone (or compatible version) using your knowledge of the product, that seems like a clear case of infringement.
Their layout is pretty busted on Safari :(

They use flash for display and XMPP polling with ejabberd on the backend. I can understand some of the motivation for this now, but I wonder how much will be obviated by HTML 5 with server-sent events and Web sockets. I guess it will depend on how quickly those things make it into IE.
I think that it is more of a fractal pattern. For instance, graphics is supposed to be the view layer, but the implementation is full of mathematical equations, which are controller type objects. Ivar Jacobsen says all objects tend to fall into one of the three categories (although IIRC he doesn't use the term MVC).
I have just given it a quick skim. I hope that you have put anti-spam measures in place to prevent scripts from automating submissions to your system and using it to send email. A few ideas:

* Original creator needs to register, use a confirmation email to verify them.
* ReCaptcha for other writers
* email confirmation before doing the final delivery to the friend.

Also make sure you have the creator write something personal for the recipient to see when they get the delivery email. I get e-cards from my relatives all the time and I always delete them.

I would also give them the option of downloading a PDF of the letters.

Good Luck!
No, it is semantic tagging based on RDF, stored on semantic databases like Freebase and DBpedia.

Practically your tags will be part of an universally shared, searchable database ... that's the real time data web baby! :D
Should start a complimentary dev shop for http://blueflavor.com/
It is tagging, using RDFa. The "new standard" in the headline has a new semantic namespace, but the cool part is a new XML namespace, with a nicer way of writing RDFa tags. Example:

<body xmlns:ctag="http://commontag.org/ns# rel="ctag:tagged">
<span typeof="ctag:Tag"
rel="ctag:means"
resource="http://dbpedia/resource/Twitter />
<span typeof="ctag:Tag"
rel="ctag:means"
resource="http://rdf.freebase.com/ns/en/web_2_0 />
</body>

This relates your page semantically to the concepts "Web 2.0" and "Twitter".

You have a lot of people who want to crash in a city, a lot of people with spaces and you just need someone to bring them together.
You're both correct/wrong. (Except that the premium store brands are not "excess" - they're planned that way.)

Some store brand products are premium equivs while some aren't. (Some stores even have two brands so they can compete with the premium with the same quality at a slightly lower price and at lesser quality at a significantly lower price.)

There was a big Harvard Biz Review article about store brand strategies several years ago.
I am sure difference will be significant.
I'm warning you against using a complex and error-prone protocol where you don't need all the complexity. You might end up using OpenSSL anyway, but using OpenSSL to perform an RSA encryption is vastly safer than using OpenSSL to verify a certificate chain.
I'd be interested to know the name of the "band" and what kind of music they made (assuming it wasn't just pirated material).
I disagree. I don't find either bottle hard to get ketchup out of. But the big difference is what happens when you're done getting the ketchup out. With a glass bottle, I'm left with a plain glass bottle (and metal screw cap) that I can recycle anywhere, or use for just about anything. With the plastic bottle, I'm left with a weird plastic bottle that's really only designed for dispensing one thing.

Reusability is a big part of usability. Generic glass bottles excel at this.
I endorse our new food-based system of rating companies, and expect it will eventually displace Moody's and S&P.

CPAP raises pressure all the time (stands for continuous positive airway pressure) so it avoids collapse at any time, not just during inhalation. I never heard of problems during exhale but if they exist CPAP should be quite effective anyway given that success rate of the machine is pretty much 100% when used correctly.

It is also true that in quite a number of cases there are better solutions that using CPAP: most OSAs (obstructive sleep apnea) are due to obesity and losing weight would be a much better way to deal with it. Alas, lots of people find it easier to stick with a mask for the rest of their life rather than changing their daily routine (ironically my father is one of those, I am afraid).

I take issue with this in the sense that you NEVER make something from nothing. True, you turn intangible ideas into physical realities, but in doing so you are leveraging your time, talent abilities and the sum total of your life experience. That is far from 'nothing'.
Ooh. I've never heard this term "butterfly market" before, and I might like to know more about it :D

Delicious very explicitly did not have comments/discussion/etc in order to make it a placid place. This probably cut down the engagement, because there were no discussions to be in, etc.

I believe that most social features are really just mechanical coping mechanisms. Generally to deal with traffic, but some for spam, trolling, etc. We need to come up with some better coping mechanisms. (And news.yc has been inspiringly innovative in this regard.)

Sorry, it's a common "term of art" in the food sciences.

Basically, it is blindly tasting three samples, and trying to tell which one of the three is different. (The other two are the same.) So, if you are testing a new supplier, you can give the subjects two samples from the old supplier and one from the new supplier, and see if they can pick out the odd one with any kind of statistical significance.

The key factor is that it is not attempting to measure "which tastes better", but rather, "which tastes noticeably different".

Can anyone actually prove that forcing everyone to identify themselves would cut off trolling? Everyone seems to take that as given, but I don't see the evidence. Especially if you define "trolling" large enough to include things like merely being anti-social, or being voluminous, or just anything in general that would make you not want to be online.

You might cut down on the trolling, but merely, say, cutting it in half isn't going to change anything.

I wonder if being mindful of proper hydration would allow you to drink and still sleep in the shorter cycles? Hmm.

I found last summer that changing my diet to mostly raw foods allowed me to sleep much less and still feel awake.

Anyway, it's nice to see somebody who has made this sleep schedule work for them and still maintains some flexibility. That's the chief complaint I have read is how rigid you have to be with it to make it work.
Implementing your own protocol is far worse than taking SSL and all its "complexity", which is there for a reason.

In fact, never implement your own cryptographic protocol unless you _really_ have to. And even then, think twice.
Possibly truly stupid question, but what is the attack on md5ing passwords if you also generate a random salt for each user? I could not find anything online in the past ten minutes that suggests an attack, except for the md5 collision problem.

I don't understand the collision problem very well either. I know it's been used to crack a certificate here or there, but it seems like it took a lot of resources to crack one password.

In that case, it's not "lower quality product" now, is it?

I'm concerned about the lack of revocation that comes with bundling a key in source. Shouldn't you warn people in your note that if the key is compromised, you're going to have a difficult time?
The space shuttle has been a huge waste of money. AFAIK, not a single significant scientific discovery. Robots/Computers make by far the best astronauts.
This is all the more critical when you consider how the usual web developer handles the complexities of chained certificate verification: namely, by disabling verification entirely, and instead trusting every upstream certificate as offered.

For example, as of Rails 2.3, ActiveResource (the default RESTful web service API client used in many Rails applications) disables all SSL verification whenever SSL is used, without so much as a configuration flag to enable it again.
That is a good thing I guess - you are not interested in them, and, I am sure, they are not interested in you. Win-win!

Everything is moderated to the extent that you can choose to remove yourself from the situation. Moderation in some form has to exist to limit the chaos. It's not black and white either, sure anyone of a certain level of popularity will get trolls to some extent, you are right. That happens in real life too. I'm just saying that it matters 'where' the discourse is taking place and it matters who is involved. If you and I where having this conversation on Reddit, somebody would probably have trolled us already.
Given that any mutation might occur, one genome might evolve to a horrifyingly huge number of children genomes over many, many generations. Deletions and copying allow for potentially any change to be made to the organism, and it will be added to the species' pool if the creature survives.

Yet again, more conjecture where people are telling me stuff happens without actually ever demonstrating it. This is more pseudo-scientific BSing that produces garbage that sounds reasonable yet can never be tested or validated.

Show me the money. Show me the actual process happening where one genome evolves into a horrifyingly huge number of child genomes. Show me the live mutations where a school of guppies eventually produces guppies with legs. Is it really that hard to ask of science to show me the process that supposedly produces all these results??? Results don't logically indicate a process until a process is shown to produce those results.

Isn't that how we validate scientific theories? We claim a Higgs boson exists, and then we build the LHC to empirically validate that assumption, right?

Evolution is much more gradual than you seem to think we're claiming.

I knew people were going to be picky over the word "sprouted", regardless I am well aware that the conjectural claims of Macro-Evolution include an extremely long period of time.

Also, I think it's pathetic that this comment was hidden from the public.

That's what happens around here. A bit of legitimate skepticism, people get their beliefs challenged and they drive-by down vote without responding.
