"well you guys also have margins too."

of course. How can a business succeed without any margins ? The point they are making is that the margins are ridiculously high that these stores charge. They are claiming to reduce those margins.

"Here is how a cheap mattress is marked up"

I browsed through their website. They don't claim to be a luxury mattress and their point is more about a reasonable mattress for a reasonable price. Of course there never is a limit for how much you can pay for anything. Think a $15000 Honda Civic vs $100,000 BMW 7 series.

I think you are being a little too harsh in your criticism even though trying to be constructive. It may not be all marketing as Amazon reviews are pretty good. And Yes, Amazon reviews are definitely worth it (being an amazon prime member who orders at least 10-15 things a month).

> Contrast that with Solomonoff induction which has a rigorous grounding and which offers hypothesis testing and rejection as a trivial subcase.

I may be wrong, but I still couldn't find anyone that could convince me that Hume's response to induction was not valid. From here (which was linked to in the Solomonoff induction wiki page) http://en.wikipedia.org/wiki/Occam%27s_razor#Practical_consi...

> The pragmatist may go on, as David Hume did on the topic induction, that there is no satisfying alternative to granting this premise. Though one may claim that Occam's razor is invalid as a premise helping to regulate theories, putting this doubt into practice would mean doubting whether every step forward will result in locomotion or a nuclear explosion. In other words still: "What's the alternative?

Again, and this is also my opinion, I think we're afraid to admit that either we don't know anything at all or that most of the things that we "know" are based on intrinsic faith, with the accent on the word "faith". Granted, this is at least a 2,500 years problem, dating back to the Old Greeks.
But that still means that the browser has to determine if it's a single tap or double tap before sending the pointerup, so it'll arrive after the 300ms delay.
> Corporations like artificial scarcity, so stuff can be owned, capitalized and exploited for profit.

That may be true of some corporations (most notably in companies that have already achieved success and thus have an incentive to maintain the status quo), but it's not a universal rule [1] and patents aren't the only method of maintaining artificial scarcity [2].

That probably improves things - certainly, it eliminates the risk of "I gave and the research didn't happen anyway" - but (as typically employed) it does not eliminate the issue: the odds that my contribution will be deciding is low.

If you had a contract that required defined (possibly in terms of wealth/income) contribution from everyone and would only go if unanimously accepted, that would eliminate this problem but raises obvious logistical issues.
Re. proper keyboards - the market says otherwise. There have been plenty of Android phones with hard keyboards but they've not sold in sufficient quantities to make it attractive.

If there was a market for it, people would be making them, if you disagree with that they what are you doing on here, your fortune awaits...

Also worth seeing kids who've never used a physical keyboard to any great extent. I've seen them doing what must be close to 60 words a minute on a touch screen (tablet rather than phone but still). If you're used to it a touch screen keyboard isn't a massive limiting factor.

EDIT: This is interesting: http://psychology.wichita.edu/surl/usabilitynews/122/ipadtyp...

A study showing netbooks to have a typical typing speed of around 60WPM vs 40WPM for iPad, but interestingly it mentions that none of the participants had used an iPad.

I'm guessing that someone with significant experience on a particular OS / soft keyboard with correction could close that gap pretty sharpish.

EDIT2: http://thinkertry.com/2012/10/30/typing-speed-test-iphone-vs...

Someone testing iPhone, iPad and keyboard two years running:

2011: iPhone: 57 wpm, iPad: 60 wpm, Keyboard: 71 wpm
2012: iPhone: 51 wpm, iPad: 75 wpm, Keyboard: 82 wpm

It seems that practice does indeed close the gap. Given that the total install base for touchscreen devices will exceed that for PCs in the next 12 months (probably next 6), that greater level of familiarity will shortly become standard.

Being understanding doesn't mean you have to share in everything, together every moment.
That's the thing though (I agree, it's not a nice list, but it's not nice to remove features either). Who says they have a mandate to do the balancing this way? It's their software to do with as they want. That's less mandate and more unilateral.

ngTouch is why I ought to get round to upgrading to Angular 1.2.x (currently on 1.0.x).

Its possible but it is now improbable that there are strong critical patents in H.264 which aren't either in the pool or at least owned by a company that participated in the standards setting (and are therefore bound by FRAND commitments). The reason I believe it improbable is that anyone in that position has hit the jackpot and are entitled to fees related to virtually every phone, television and blu-ray player currently being produced - there is no reason to wait further they can cash in now.

VP8 has not been widely deployed (at least in hardware) to anything like the same extent so the possibility of lurkers is greater.

Well, there is tons of types of springs and more importantly spring layouts. Some manofacturers will use less springs than others, and that is very important.

Personally I prefer spring mattresses over foam mattresses. They last much much longer as dangrossman commented, are more reliable and also much firmer. And also you can't leave aside the weather factor because spring mattresses are way more breathable than foam-only mattresses. We, for example, avoid selling foam-only mattresses to people that live on high humidity areas because there is a high chance they will return it with humidity stains.

Normally I would go for a pocket spring mattress ( I think that's the term in English for a mattress with individual sealed and padded springs ) with a decent amount of memory foam on the top. That way you get the firmness and breathability from a spring mattress plus the comfort of a nice soft memory foam layer.

Ask HN: web or iOS calendar app that hides blank times?
I'm looking for an app that by default, hides any blank times. Every one that I've used looks something like this:

8am: Event
9am
10am
11am
12pm
1pm: event
2pm
3pm
4pm

And it's really annoying and difficult to read. Are there any calendar apps that just straight up show the events and times, minus any filler time?

Big Pharma has no incentive to make a cheap cancer cure, it makes too much money off of current cancer treatment.

Except for their competition from other companies making other treatments, and the fact that their patents will run out eventually. Do you really believe that they're not interested in finding an actual cure? I believe that you're viewing these corporations as giant faceless evil monsters. But these corporations are run by, and certainly have researchers who are, real people whose mother was killed by cancer, and worry about that gene popping up in their own children.

the capitalist approach leads to biased results, again, because research has no incentive at that point to be honest

Certainly we've seen an unfortunate amount of dishonest results in recent years. Do you have any evidence that the problem is worse in the private sector? My expectation would be the opposite, because in the private sector you've eventually got to sell something that works, whereas in the public sector you can just keep applying for more grants, leaving behind your previous bogus results.

Let me also throw in that publicly-funded research is biased in a different way. Where the funds go is targeted not on any rational basis, but based on where the well-organized constituencies are. So what we see today is that per-victim, the amount spent on AIDS/HIV research is vastly disproportionate compared to other maladies whose sufferers are from more diffuse demographics. That is, comparing funding of AIDS research to, say, colon cancer, we spend FAR more for each AIDS patient than for each colon cancer patient. The politicization of science leads to waste such as the recent Solaris nonsense, where we allocate funding based on politics and posturing rather than where it will have the most utility across the whole nation.
a.) use a mattress protector. they are waterproof and prevent transfer from body<->mattress.

b.) people naturally sweat and have oils in their skin that get transferred through sheets. it's normal to have discoloration where you sleep. that's another reason a mattress protector helps (easier to replace a $50 cover than a $$$ mattress).

I think one of the major hurdles to overcome with online mattress sales is perception of shipping. I do a lot of online shopping and have no issues with it. If I were in the market for a mattress, my first thought about online mattress sales would be "It's going to be an arm and a leg just to ship it." and would perhaps not even start the online process. Just my opinion. (From Canada so Amazon Prime and free 2 day shipping doesn't apply to me).

XKCD: Physicists -- http://xkcd.com/793/ :-)

EDIT: I linked to XKCD here... cuz never miss an opportunity for xkcd! Also, I just finished reading the article, so I'll add my comments on the content.

The parent post (for this comment) contains a rant about physicists but has no specific rebuttal of the article.
David Deutsch's arguments seem very sensible to me, in a completely non-mystical sort of way. I feel he asks questions pointing to the heart of AI. Regarding moving goalposts and stuff, you might like to read Freeman Dyson's (excellent and insightful) article on 'Birds and frogs' where he comments on such things. Deutsch is approaching the problem like a bird, typical AI researchers are approaching the problem in a frog-like manner.

And oh, to state possible biases on record: I'm a physicist :-)
I'm surprised more people aren't talking about in-home streaming. To me, this is something I've wanted for years. I've got a state-of-the-art machine I like to keep in my basement (cooling), and with this I'll (hopefully) be able to play hardware-intense games on my media center PC upstairs.

> This stuff if learned organically by doing it on real world projects. It's scary at times to think that you just can't teach this stuff.

Yup. And with the supply being so low, it's hard to get a DBA (you'll probably have to steal one from another business), so people are flocking more and more to DBaaS, and DBaaS providers are more than happy to propagate the fiction that "you don't need a DBA, you have us!".

It honestly doesn't bother me much that they make these statements; it's marketing.

On the other hand, believing those statements harm our customers; they spend time and money to migrate to these providers and find out the hard way that they still need someone who can handle their DBs for them. That does bother me.
I'm not convinced this makes things worse for any user. Can you think of a case?

The idea is applying feminist theory, which (among other things) analyzes the way gender-normativity shapes intellectual constructions, to the field of programming languages, and see what would a programming language derived from that critique look like.

By spliting languages in feminist, imperative, functional, object-oriented, and logic, you're telling me that the four traditional types of programming is somehow not suitable for a feminin mindset.

I believe the idea of a feminist [X] is not that X is unsuitable for women, but that it was shaped by men (which is true in the case of most programming languages, and probably paradigms). Maybe this doesn't matter, and a programing paradigm made by women would look the same, but you don't know without exploring the possibility.

It's similar to Feminist Aesthetics[1], Feminist Epistemology[2], etc.

What are some typical queries look like? Several minutes for searching 7M records doesn't sound right. Are the columns indexed properly?
> Unfortunately, since there are 30 different columns that can be searched on

That's your first problem. I bet the schema isn't normalized and these are all varchar columns.

~~ Normalize your schema ~~ such that the main table is a set of integers. JOIN on PK and index whatever is required. Trust me, MySQL is fast when you do it right. I have tables with 650M records and lookups are just as fast as day 1. Keep table size AS SMALL AS POSSIBLE (less columns, use ints, etc).

Use date_ids & time_ids (from standard DWH techniques) if you are storing datetimes, not datetime fields (default indexing them is 1 second resolution which is stupid).
Ah, ok. That makes a bit more sense.

Although if it is truly impossible to know X, but everything works as if X holds, we might just take the easy way out and assume that X until proven otherwise. But that may be my personal philosophy.

Hi guys,

Love the idea, quick point of feedback: it is unclear, from a cursory glance, whether your prices refer to bed or bed+mattress.

The floor vs. frame view is great, but the price doesn't change- so are you just selling a mattress? Should you say mattress instead? Are you calling a "bed" a mattress and the rest is a "frame?"

Ask HN: Architecture of Node in front of Rails
Hi, I'm looking for architectural advice. What is the best method for placing a Node JS endpoint in front of a Rails back end for JSON API endpoint and Administration? Why? I am building an app which I would love to use Node for, but I don't want to re-invent the wheel (eg: rails has active admin, copious build tools, etc)

I'm looking to use node for responding to all Consumer facing UI requests, and placing calls to Rails - which Rails will serve from Postgres. Is the best manner to simply chain the calls? (Eg: UI places api call to node, and node calls the rails api to return the data?

Any suggestions would be appreciated. Thanks
