Thanks for the feedback, and I understand your concerns. I'll address them below.

>> Even if mattress retailers are making a fortune on margins, well you guys also have margins too. And a retail price of $299..to..$499-king tells me that your mattresses are very low end.

We of course have built-in margins on our products, and we try to keep it as fair as possible while supporting our operational overhead. But to write off our beds as "very low end" is a misinformed assumption. We have internal pricing of well known mattress brands that are considered high end by many and they have the same if not lower costs as ours (due to volume and manufacturing in Mexico/China).

>> It is just too thin. Less than half the thickness of a regular mattress.

We have a 10-inch model (double the thickness) coming out soon. The price won't be too much more than the 5-inch, while offering the same level of comfort. But to be honest, we've never had a return for it being too thin.

>> the fact that is made of foam only makes it worse as with that thickness it will unavoidable deform with usage

Our foam should last 5-7 years before there is any deformity/compression. We've done thorough cycle tests in a lab to test this.

>> Then there is the foam density, that I can't see anywhere in the specs. And as you can guess when you import materials the bigger the density the more expensive the foam sheets are.

The foam in our bed is roughly about 2 lbs in density. There is some variance as with any foam manufacturing process. Our foams are poured and crafted in California, and 3 different layers provide a blend in density that's proved to be comfortable and durable. To give a point of reference, Tempurpedic recently dropped below a 1.8 lb density base foam, and that is considered high end. They used to use 2 lb but they reduced it to increase their margins.
There never was any delay for touchstart/touchend events.

If you're using onclick/mousedown in your game, then change them to touch events (touchstart and whatever Windows Phone does). These work without delay regardless of viewport settings.

If you have existing codebase that can't be easily changed to use touch events, you can use FT Labs' fastclick to emulate onclick with no delay (the library is aware of latest Chrome's change):

I bought one of these mattresses recently. The 10+ year old spring mattress I had was on its last legs and I found myself waking up with back pain.

I happened upon an AMA on Reddit by a guy in the mattress industry and someone mentioned T&N. After some research I decided to give them a try. 30-day money back guarantee and all.

I think I knew I didn't need the 30 days after the third night. I was sold. I slept more soundly those first three days than I had in years prior.

Some things to consider:

- The smell. Its the case with ALL foam mattresses so this is neither unique to T&N nor their fault. But it goes away pretty quickly.

- If for some reason you don't like it and want to send it back within the 30-day guarantee period I have no idea how you'd get it back in the box. I think maybe they should include instructions somewhere just in case. That or provide a "Space-Bag" style wrapper that you can use.

I highly recommend trying them out if you're in the market for a mattress!

There's a certain amount of twaddle in Deutsch's arguments in general but it's quite hard work wading through the argument to see what's wrong. An iffy statement of his here is "the field of ‘artificial general intelligence’ or AGI — has made no progress whatever during the entire six decades of its existence." Which is tricky to totally dispute because of his vagueness as to what AGI is. But let's assume he means thinking like a human. Well fair enough no computer thinks like a human yet but a lot of progress has been made in that direction such as Watson in verbal processing and the Google cars in geospatial awareness. So the argument is kind of misleading. I find his arguments in physics similar - basically not much good but written in a form that is hard work to dispute.
you are right, I didn't think on that
I am always cautious of memory tables. They don't support transactions, for example, and don't work well multi user.

Really, the first stop is to use tokudb backend in mysql. If its still slow, and if you have a small subset that fits in ram, just put that straight into a hash table in app space.
Great work so far!

Your bed solved a very specific problem for me, and it may be a valuable market for you to target. My job requires me to travel to different locations for long periods of time, and I needed to find a bed that was very comfortable and portable. Cots and air mattresses are poor long term solutions. Your shikibutons came up during my research as one of the best values. I purchased your mattress and a futon from shop4futons.com. When broken down, the whole arrangement packs down to a very small size. Now I sleep comfortably every night knowing that no matter where my job/life takes me I can always find a good night's rest.

Thanks and keep up the good work!
>"That table would entirely fit in InnoDB Buffer Pool "
I would like to see how it fits in the pool on 2GB linode (mentioned in the article), also, I like that people try to think before saying "big data" and grabbing some NoSQL that is not very good fit in some places or gigantic mapreduce in 67 servers.
GoldenGate is for multi-master replication and shares a lot of the challenges you'll find with any multi-master replication solution.

No, I was referring to Oracle RAC, which does away the need for sharding. All of your nodes see a complete and comprehensive picture of the data on a shared set of disks.

> I guess I'm just biased towards solving scalability problems at the application level.

That's a totally valid strategy, and indeed, an option that many companies go for. But you're just shifting complexity from one place to another. Either you're going to be building in complexity to make your application aware of data distribution, movement, sharding, and so on - or you're going to use a more complex data storage platform like Oracle.

And SQL tuning is a skillset, much like writing good code. If you are good at SQL tuning, it's not that hard.

My point is just that it depends on your business requirements. I personally think Oracle's price point is so high that I would never use it. But if money were no object, and I was designing an application, why would I want to have my application have to think about where the data lives?

Wouldn't it be a lot simpler to just say, "go here for your data", and let the dedicated application deal with that?

Or put another way, in the same way it seems insane to shove 100k lines of business logic into the database layer, why doesn't it seem insane to shove 100k lines of data management logic into the application tier?
Oh, you actually watched the videos? Here I was just repeating shit I read somewhere. Yeah, we're done here, believe whatever the fuck you want, I doubt you could understand the context I'm talking about anyway.
I think we're already pretty convinced - at least, I am. :) We're just checking to make sure we have consensus; so far I haven't seen any objections.
I can't tell whether there's a frame in my cart or not. I'm interested in pricing with and without a frame. It's not clear to me whether the pricing and the cart includes the frame or not, and whether there's an option to do frame or not.

We just purchased a bed for our daughter a few days ago on Amazon, and totally would have purchased yours if we had realized there was a startup making beds here in the USA with a no-nonsense style. I'm honestly not sure how we missed you during that process. We had to search hard to avoid things with smelly chemicals and cheap construction like particle board, too.
Are you saying that an Ikea mattress will sag after just 12 months, or are you actually just saying that yours won't and leaving it up to the reader to infer that an Ikea one will?
Just the mattress. Though your confusion is valid. I wondered the same thing before I bought mine.
You're right, I also thought after having posted it that I was too harsh. I think it was due to the fact that I partially live this business on a daily basis and found some of the facts not trustful. Specially bearing in mind the product being sold is closer to a mat than to a reasonable mattress.

I think that harshness prevented me from making clear the two points I was trying to make:

1. A warn that everything has its price. Some people will mark up expensive, some people will mark up way cheaper, but at the end there is normally no such thing as free lunch and on average you get what you pay for.

And more importantly,

2. That I believe that these guys made an awesome work around marketing. But not from a bad point but the opposite. A great website, great picutres, great pictures on Amazon too like for example showing the customer how the mattress looks like when folded and when shipped! Pretty infographics. Tons of facts about their mattress. Great choice of payments methods, etc..
I don't find the logic on this site
He certainly passed on a significant portion of the rights or that server wouldn't be authorized to receive and permanently store the emails in the first place.

That's a really good point. We should do a better job at communicating that.

For clarification, we only sell a mattress at the moment. It is designed to be comfortable placed directly on the floor as it is on a bed frame.

Thank you.

Hi Jeff!

I assume this is a reference to the charge per 1M I/O requests on EBS.
I am saying there is NO WAY MySQL sucks at 7M records. That's just jacked design. Talk to me at 7B when you need to reach for something bigger.
Google has an incredible user experience considering its depth (although many would argue that being feature rich is a negative when it comes to user experience design, take Netflix's UI for example, which has only become simpler over time).

This reminds me heavily of the IFTTT recipes (https://ifttt.com/recipes). Google has so many parts that sometimes you need a little guidance to see how they fit together in a useful way.
I'd agree that the paper makes claims it can't begin to back up in the real world - I originally said pretty much that. But to say that we couldn't come up with enough facts to prove something seems to show a lack of imagination. No one's saying it's easy, but with good data and smart people it's not an unsolveable problem.

Really, though, I'm not sure the conclusion would do much to convince people. The debate between socialism and capitalism has never been purely economic. Most people's positions have a lot more to do with their core values and what they believe is fair.
It may be rooted in reality. Not that they can turn on microphone on any phone, but that they were able to hack someone's phone to download firmware, for example.

BTW, there are recent news about FBI secretly activating webcams:

Governments should fund science that benefits society and that wouldn't otherwise be happening in a capitalist system.

But that's not what ends up happening. The funding doesn't get allocated such that the total utility would be maximized. Instead, it is directed toward those areas having a constituency that's better organized.

The result is that AIDS research -- its victims being fairly focused in a particular demographic -- gets about 350x more research funding per victim than does COPD. It gets 112x more than Hepatitis C, and 33x more than Alzheimer's disease. [1]

Government funding equals political funding. And this is what leads to scandals like Solaris, too. The government is not able to make rational decisions, as much as we might tell ourselves that it does. In a democracy, the funding will go to those causes that can muster the most votes.

Really? I see that sentiment quite a lot, but I don't really think it holds. A mattress is definitely something I'd want to try before buying --- comfort, like taste, is such a subjective thing that no number of online reviews could really replace just lying on one for ten minutes.
There's a pretty decent discovery mechanism. The more you rate, the closer you are to the front page. It's not perfect, but I don't think I've gotten less than, say, 50 people rating my games (http://www.ludumdare.com/compo/author/mscottmcbee/ If you're interested).

Rate others, leave comments, and people will play your game.
That's your phone's fault, not the website's.

Not $20 but $0.20. (after the first free 100,000 and until it drops to $0.10 after 5 million) although you may have to sign a license with MPEG-LA to take advantage of the free 100,000 and potentially submit to audits so there are risks/costs.

I don't know how direct the distribution from Cisco to the end user has to be to be legal although I can imagine a range of possibilities for this I don't know if they would be practical in your situation. I imagine that you could ship a tool that creates an install package to be used on the non-connected devices and downloads the binary from Cisco and adds it to your install bundle but that is still an annoying extra step.

Practically I don't see anyone coming after you (and certainly not getting real damages) if you did include Cisco's binary with your product - it would be hard to see the real harm or damage caused.
The domains table currently has 84 fields. We collect metrics from various sources, so reducing the number of fields is not feasible. All the field types are the smallest that we could use - e.g. tinyint(4) instead of an int etc.

Since there are so many fields with data from multiple sources, we have queries running searching on individual fields. Due to this we need to have many indexes. 4GB of the 8GB is the size of the index itself.

You seem to think that an organized political group being pretty consistently wrong is a reductio ad adsurdum...?
I think that's a fair argument, and one of the reasons I switched to T-Mobile. With AT&T, et. al., if you don't get a new phone in the same month that your contract ends you're getting screwed on your next bill.
I wonder why they didn't stick another L word at the end... like High Energy Laser Light... to make it HELL MD. :)
Article aside, I think you're making a great point. Upworthy has been incredibly successful using A/B testing with their headlines to get traction on basically any article, to the point that other larger media companies are taking notice and are even worried.
From the comments, it sounds like the preference pane was hidden and had to be enabled by installing 3rd party software. Having experimental features in software that are hidden (but included for testing in limited situations) is not surprising, nor WTF worthy.
Java PaaS providers - from a developer's perspective
I can't agree with this. The two-tap is my most common gesture on my phone's browser. A two-finger tap would be extremely awkward one-handed.
How are you deploying? You 'should' push a tarball to s3 and have web nodes pull it down.

Red-black deploys via AMI changes are one way for sure, but those seem to be usually done via separate scaling groups entirely. Netflix has a lot of automation around this (see Asgard and AMInator)
That's because the Windows Phone 7 browser is unfathomably awful. I say this as a one-time WP7 user and a web developer.

I felt guilty for using it because there was an outside chance it might make someone have to develop for it.
We looked at that, but the thumbnail would not be used as google displays both thumbnail and full sized (on mouse over) versions.
A few years back I shared office space with an "email marketer", and even then he would tell me that each image URL contained a hash as part of the file name. This hash is linked to the email address. How would they be able to prevent that? Even if Google pre-fetches it, it still would (possibly harmfully) confirm they had saw it. Even if they didn't.
Very cool! I know code mirror had vim mode but this. This is something way more awesome.
The father of Erlang, Joe Armstrong, lauds this language every time he gets a chance. And I think the hate on Erlang syntax comes from the fact that a first stab at Erlang was done with Prolog. But I actually like the Erlang syntax after I got used to it. It reads like English ~
You just used the words "insert", "explicitly", and "private." If we can't agree this constitutes hardcore pornography - however small in scope - I think we'll just have to agree to disagree. :)

Not something I've ever desired. Either in the home or externally rendered. In the home there's absolutely no way my consumer hardware is going to to keep up with 1080p or 2160p streaming over a network (heck HDMI barely manages), and externally there's no way you can possibly play a game with the sort of latency (400ms+) you get on Australian internet connections.

oooohkay. you can run with that then.

Somewhat confused. I'm sure they demo'd shooting down mortars before.

This version does seem to be mobile though so perhaps thats the breakthrough.
Here is a decent analogy I read:

>Suppose we have a computer program which makes books. All of the commands which tell your computer program how to write a book are stored as sequences of 0's and 1's. Also, all of the letters, punctuation marks, and formatting symbols (line break, indent etc) are stored as specific sequences of 0's and 1's.

The commands which control the computer program and the actual text of the book are both stored in the same file. Up until now, we thought that these were placed side by side in the file, so you would have a segment saying "at 6am every day, print the following text in 12 pt font, and bind it in a hard red cover", followed by a text containing segment, and then another command segment saying "when you finish, print a copy of the book 134 positions further along in the file.

We thought this was the case because we have known the sequences of 0's and 1's that stand for each letter for a long time now. When we looked at a file and attempted to interpret it as If it all stood for letters which made up words' we would see something like "fffffgfgy6- fsjjjjjj the quick brown fox jumped over the lazy dog.bttt68-%jjjjjjfffffffff". After a while, we learned that the 'gibberish' segments were actually full of meaningful statements, but they were in a different language and contained the commands for the program.

Now getting to today's article, this group has found that inside those sections which code for the actual text of the book, there are some commands that run the program. This is accomplished because there is more than one way to write most of the letters. As an example, you could have one segment of text which says "It was the best of times, it was the worst of times", and another segment which says "It was the best of times, it was the worst of times" and also tells the book program to bind the book in gold leaf. And the only difference between the two is that the first one wrote the 's' in 'best' as 00010110, and the second one wrote it as 00010111.

> Property rights are anathema to government construct

That's a big word there, and I suspect it doesn't mean what you think it means. Property rights are a government construct. It's one of the primary reasons why governments exist. Without government to enforce these rights, you have no real claim on what you consider yours. Anyone can come along and take it away, and the only recourse you have is to steal it back, or steal something similar from someone else.

Since that's not a very ideal situation, thousands of years ago we decided not to do that anymore, and anyone who still did it, would be punished. That's basically what government is (and I'm amazed I'm even explaining this to anyone over 8 years old).
Actually, fair point.
Narcissism is the very definition of a first-world problem. As a personality style, it's far more prevalent in advanced societies. Once you get beyond mere survival, you start seeking self-actualization, which means people start trying to fulfill their own potential. This is a double-edged sword. On one hand, societies that are more narcissistic (like the US) allow individuals to do more things for society on their own. On the other hand, societies that are narcissistic expect people to do more.
I'm surprised we aren't seeing these on ships, since those already have huge amounts of electricity available to potentially power them and already have point defense systems based on guns. Or maybe gun based systems work fine, but can't be used on land since 20mm gunfire that goes up is going to come down somewhere, and is much more likely to come down somewhere bad on land then on sea.
I think that my understanding of my chosen skillset / profession is good enough to know that I am not in, or anywhere near the top percentile for it.

I'm guessing intelligence isn't the prevailing factor here. It has more to do with awareness and self acceptance.
If this system is actually combat ready any time in the near future, it has very large geopolitical consequences. The Korean peninsula has mutually assured destruction (and thus stability) because the South could destroy the North easily militarily (and with the help of the USA), but not before the North shelled Seoul (the South's capital and largest city) to the ground with artillery rounds.

Because Seoul is so close to the border, it has allowed the North to have a standoff with the south without needing a nuclear deterrence. The North will need to step up their second strike nuclear capabilities, or get strong assurances from China that China will step in in case of invasion if this defense system works and is deployed over Seoul.
Actually civil servants have been churning this stuff out since the 50s, if not before. Politicians ignore it of course, but if you think this is a new thing, then you have fallen into the common data science trap of not knowing there's nothing new under the sun. Which is odd really since anyone calling themselves a scientist of any sort should be able to do some research and not reinvent the wheel.
