Good lineup. However, I think that #4 is only appropriate in beginner's guides—docs always should have some boring reference section with quick navigation. HTML5 boilerplate lacks that. Jokes get old fast.

Perhaps some good examples should be mentioned… I think, SproutCore handles points 1-3 very well (http://guides.sproutcore.com/), but lacks #5 a bit. Django's documentation seems to have most of these, too. (These aren't HTML UI frameworks, however.)

> I see very few of them looking for holes in their arguments, or trying to prove their hypotheses wrong.

Where have you been looking at the scientists' work? Have you been following their peer-reviewed publications to reach the conclusion that they don't question these theories?
Yes, you are right. If a domain is not registered then it can not have any pagerank. I taught that some of expired domains can still have pagerank but i think i am wrong. But what if someone only wants to check the pagerank of a website? If I put one submit button, he needs to check the domain availability first then can check the pagerank. It breaks the simplicity i think.

Thanks for the comments.

This is absurd. Saying that Apple doesn't have the ability to build a multi-tasking OS is just ridiculous. They didn't do it with OS9 because they were trapped by the weight of their legacy, and they ended up making the hard choice of starting from a fresh base to accomplish it.

Your implication that somehow real multitasking is some kind of black art that nobody at Apple understands and only exists because they acquired Next is ridiculous.

As for iOS, Apple totally made the right call here and introduced it when the hardware and battery became ready. Did you ever use a G1? They were ridiculous, even today, Android is a complete mess when it comes to doing a good job of sandboxing apps and their use of CPU.

I love Android and have carried one for years, but their biggest wart is just that. Everybody used to joke that if you used WindowsMobile you had to use a task manager to keep it running, Android isn't far off. You get a lot of power through its use of multi-tasking, but because they are less strict than Apple you also easily get into a state where your battery lasts for shit.

iOS is far, far, stricter in this regard, and it can make it a pain to program to, but the overall user experience is way better. For the vast majority of apps the user has no idea whether multi-tasking even exists.. all they know is that they leave the app and when they come back things are just as they were. iOS's strategy of just saving the state and killing everything works brilliantly for 80% of the apps and has made the phone have a fantastic user experience.

Yes, they had to evolve to allow background services, and they did, but carefully.

Enough with the fanboyism, each platform has its strengths, but make your arguments on reasonable foundations.
Seven studies were found which did report an association, while 24 could not find any association with electromagnetic fields. However, of the seven positive studies, two could not be replicated even by the original authors, three had serious methodological shortcomings, and the final two presented contradictory results. Since then, several more double-blind experiments have been published, each of which has suggested that people who report electromagnetic hypersensitivity are unable to detect the presence of electromagnetic fields and are as likely to report ill health following a sham exposure, as they are following exposure to genuine electromagnetic fields. [1]

This is the sort of thing that should have been mentioned in the article. Either through shoddy research or intentional omission the author included none of this and left it with two short paragraphs of dissent. The article gives the impression little work has been done on this issue.

Another example of shoddy science reporting in the media. sigh

iOS had multitasking since day one. How do you imagine iPhone was able to get call when iPod app was playing?
It was just not available for the third party apps, that's all.
I don't work for BlueHost but do run my own Hosting company. I'd like to offer you some counter points:

1. Web hosting industry is RIFE with fraud and are huge targets for hackers who want to test credit cards/spread warez/etc. They're not asking you to verify before giving you SSH, they're asking you to confirm you made a legitimate order.

2. This is unfortunately a limitation of cPanel add-on domains. If you don't want sites to "live inside eachother" but you want cPanel hosting I'd recommend getting a reseller account from somewhere or a VPS that'll give you full root.

3. This is for security as cPanel/exim (I assume they're using exim) route mail locally. This means on a cPanel based shared host I could go setup "gmail.com" as an add-on domain, setup a catchall e-mail account and then any e-mail the server is trying to send out to Gmail will get forwarded into my catch-all mailbox. This is a pretty big security hole but unfortunately it's part of most mailservers. BlueHost is making you verify ownership of the domain in order to prevent from exploiting this security flaw. Same vein as Google making you verify domain ownership.

I understand you're frustrated but I don't really feel you're giving BlueHost a fair shot. On the other hand they ARE my competition and if you want to try out another cPanel based webhost I'd be happy to set you up with a coupon for some freebies. :)

Ask HN: Idea Incubators? Or this: "I need some ideas"
I recently came across the following links from Google and Hacker News:

http://ycombinator.com/ideas.html
http://jacquesmattheij.com/My+list+of+ideas+for+when+you+are+looking+for+inspiration

I am probably dumb when it comes to ideas because everytime I think of the "next" big idea, it has already been done.

Would you recommened any other blog posts like the ones written by Jaques or Paul that can enlighten me?

I am not looking for a direct "here's an idea" though, only something that will make me think more about the latest problems. I want to go through the experience of a startup at least once and am willing to put in long hours and am open to learning. Any suggestions?
I was interested in the study mentioned, as I'd never before heard of positive evidence for such a phenomenon. This [0] appears to be the paper referred to. The results seem pretty bizarre and hardly support the rosy view presented in the article. In particular, the symptoms are different for nearly every trial and symptoms were reported for half of the sham trials.

This is also 20 trials with a single subject, so it's probably too early to talk about broad applicability. It would also be good to see some replications in a more respected journal.

I was trying to put myself in their situation to imagine what I would be doing answering those questions.

PG & Harj's pace is superb trying to utilize every minute.

I think the startups stand to gain much by being more open to criticism and looking for take-aways to improve their positioning, product etc., from their feedback.
I read a great book about things like this: http://www.amazon.com/Why-We-Get-Sick-Darwinian/dp/067974674...

There are several chapters about the hormonal effects of childbearing and what the evolutionary benefits are for the children. A few i can remember off the top of my head are:

Breastfeeding will often prevent women from ovulating and thus becoming pregnant. In this way mothers resources are not strained by taking care of too many children at a time and the current child will have a better chance of survival.

Fetuses secrete a hormone called human placental lactogen that inhibits maternal insulin, this leads to high glucose levels in the blood and thus more nutrients available to the fetus it can also result in diabetes in the mother during the pregnancy.

preeclampsia (gestational high blood pressure) is another similar effect where hormones excreted by the fetus raise maternal blood pressure in order to increase blood flow to the placenta.

Having a fathers testosterone levels fall during early parenting is probably a key evolutionary adaptation because it would prevent fathers from seeking new mates (in order to make more babies and thus spread their genes) in order to care for the new child. The study noted that testosterone levels later rose when the children became older, this too follows the evolutionary argument because once a child is old enough it is more efficient for the father to attempt to father more children.

By far the most interesting part of this section in the book was about male jealousy. The theory is that because it is fairly difficult for a man to tell whether or not he is raising another mans child. men have evolved to be overly protective of their chosen mates so that they do not invest to many resources (time included) and thus lower their own genetic viability. Jealousy, while present in both sexes is a much stronger emotion in men (according to the authors this is true across all cultures).

Ohhh, that's stupid, of course it had multitasking, but if you didn't understand what I am talking about you probably shouldn't reply.

Being peer-reviewed is a joke - especially when it is so easy to falsify or hide data, as was done in ClimateGate.

Being peer-reviewed is also a joke when your peers all sip the same cool-aid.

I would like to know if the reverse effect can be produced on women. Can women produce more testosterone in situations that would generally be considered more masculine? There seemed to be a very significant finding for men who just had newborns, perhaps it is triggered more by a major life event rather than specifically becoming a parent. For instance, does getting married reduce testosterone? Does losing a love one reduce it? Does moving to a new home? Makes for an interesting article and find(?) but I don't think it can be significant until it can be concluded that parenting specifically reduces that hormone.
I think any cross-platform open standard is going to be at a serious disadvantage compared to a good native environment. There are just too many conflicting interests and cooks in the kitchen. This didn't matter much when the net consisted mostly of static content but as people come to expect richer and more immersive experiences the impedance mismatch is more evident.
I missed the point you're trying to make.

Silly example aside, as a Treo user migrating to an iPhone in 2007, I was absolutely thrilled that Apple "copied" so many good ideas from Palm... the concept of the device profile (backups were effectively a system image of the device).

About the only thing I missed from my Treo was a) Bookworm app which showed up later in 18 months, and the customizable "home area code" (unfortunately still not here).

Holocaust Research Papers – An Essence of Academic Writing
One of the common topics assigned by academic institutions is holocaust. In fact many universities have specific papers related to holocaust and writing holocaust research papers hence have become a widespread activity.
I wasn't talking about developing the idea on company time. As I mentioned in another post, that clearly marks an idea for company ownership.
Not just behavior - environment too. In a world where drunk driving was common and legal I would expect fences by roads, pedestrian safe tunnels, warning lights, and other such features.

You are making the common mistake of changing a variable in isolation, without taking into account all the things that flow from your change.
It's reasonable. It would be so dangerous to be around traffic that other people would avoid it. Thus deaths might go back down, but note that there's nothing saying that everything else would be normal. It would for example be a lot more inconvenient for those that now stay away from traffic to get around.

These data should not be used to make the claim that attempting to increase safety is useless. Improved vehicle safety features, for example, has been compensated for by faster driving. That means the safety features didn't help lower deaths, but they did help everyone get around faster.
As cheesy as it may sound I find this song helps me keep in mind that I should expect things to take a lot of time and effort.

Windows 8 desktop to be 'just another app,' says Microsoft exec

http://www.computerworld.com/s/article/9219680/Windows_8_des...
You argue that multitasking was always in mind because of the underlying POSIX threads. Of course an operating system has threads. You say it was because of CPU/power usage and also a UX simplification. Do you have any sources for these claims? We could speculate back and forwards but to me it just appears you're making assumptions here.

> There's a lot of other obviously stupid claims in there too, I'll leave those as an exercise for the reader

That's not how arguing against a point works.

"drunk" is a loaded term.

Note that the different countries on that graph also have legal blood alcohol limits differing by factors of at least 4. Yet that is not reflected in the death rates.

While I do not feel safe driving at the U.S. legal limit, I do feel safe driving over the Swedish legal limit (which is 1/4 the U.S. one). While I wouldn't do it in the US, I would in Sweden.
Apple forbid data gathering without user consent, but I think as long as you prompt on start up it should be OK.
Since insulation costs less than the cost of the energy it saves, the amount of energy used to make insulation must be less as well.
I am a climate expert either, but I can easily identify a fallacy or bad experiment when I see one. I think hugh3 has written one of the most rational posts I have ever seen on HN. I think it is everybody else who is unclear on the scientific process. Being peer-reviewed DOES NOT constitute to the scientific process. Remember when every person and their peer believed that the earth was flat and it was the center of the universe? Guess what, it turns out popular assumptions are often wrong. Being peer-reviewed does very little when your peers are so eager to approve your work.

The scientific process is as follows:

1. Ask a Question
2. Do Background Research
3. Construct a Hypothesis
4. Test Your Hypothesis by Doing an Experiment
5. Analyze Your Data and Draw a Conclusion <-- this is where people are messing up; insufficient data, jumping to conclusions, fallacies, etc.
6. Communicate Your Results
Also: How do people find-out about your product (search, word-of-mouth, etc)? Why did you get turned down (when pitching to an enterprise)?
Any other devs (front end, back end and or mobile) here now on unemployment or are on and off Obama's payroll?

If so why?

1. Lack of experience
2. You did a start-up for long time & having trouble finding regular work (that's me).
3. Something else?

I hate being unemployed and feel working on my start-up for over four years alone in my garage has handicapped me professionally. Since the investment money ran out for my start-up, I have had two front-end dev jobs. Both positions were at local digital web agencies and both lasted under a year. Since getting laid off from the last job Ive had a hell of time getting my next job. I have 22 months of professional experience and 3 years of coding for my start-up.

I wonder if there are similar stories and experiences fellow members here faced? Also, what did you do to land your next coding job or what are you doing now?

An Immune System Trained to Kill Cancer
Thanks. I've kind of been working on the "build interest and a community" part. Long story short: I have a serious medical condition. I got myself well when that is supposed to be impossible. Everyone treats me like a loon and teller of tall tales. I would like to make a simulation (aka "game") because I think a more information-dense delivery method might help people wrap their brain around what I am talking about. But I'm pretty fed up with the whole thing and will try to stop there before it turns into a rant -- which is to say I have been trying to do what you suggest but I don't think it's accomplishing anything at all, certainly not anything useful to me.

Thanks for taking the time to reply.
I consider simulation based science interesting as theory (theoretical science), but it should NEVER be taken as accepted fact.

It depends on the field and the degree of accuracy. For example, hydrodynamic simulations are pretty much accurate for standard(ish) shapes. Same with lighting simulations (ie, ray tracing).

The weave bits, and Pyrex bits, found in this article are actually snippets of C/C++ written inline in the Python code (or very simplified Python), and able to access variables and such defined in the Python earlier (with caveats and when used with care), and later Python code is able to use the resulting compiled functions.

So, it's high level Python code, except when you need to write low level, super fast code.

The reality of making a very high level language compile down to high performance C/C++ is a much harder problem than "compiling" CoffeeScript to JavaScript. Both are quite high level, and CoffeeScript is merely very concise syntactic sugar for a number of common patterns in JavaScript, and maybe a few higher level constructs tacked on for good measure. But, JavaScript is effectively Scheme with C-like syntax; it was designed to be built up in this way, just like Lisp and Scheme (and it's only the lack of control over the parser and syntax that forces it to be a compiler at all; all the capabilities are there in JavaScript: closures, first class functions, code as data, etc.). Building DSLs is what this kind of language is for. C and C++ is not for building DSLs, and you don't magically get C performance by converting high level code to low level code.

One example is B::C, a Perl to C compiler: http://www-rohan.sdsu.edu/doc/perldoc-html/B/C.html

In short, the CoffeeScript approach is not at all comparable to a high-level to low-level compiler. It is comparable to a, say, Lua to Perl compiler, perhaps. From one very high level language to another very high level language.

It's not lack of interest. Weave and Pyrex, which are discussed in this article, are proof positive that people want the speed of low level and the convenience of high level languages. It's just not possible to get it via the means you've described. JITs seem to be the currently fashionable way to get closer to that goal, though it's still miles away.

Oh, and there are Lisp compilers that compile to lower level languages like C or compile very fast Lisp. Lisp is quite high level. So, when it goes fast, it is impressive. I'm not knowledgeable enough to know whether they could be used in the same contexts of SciPy, Weave, Pyrex, etc. I imagine there are big math libraries for Lisp, though...and they're probably pretty fast.

As for ooc and garbage collection: How would you write a compiler for a high level garbage collected language without including a garbage collector? And, do you believe that garbage collection is the primary reason dynamic languages are slower than compiled non-GC languages? (Hint: It is not. GC is very far down the list of resource users in every garbage collected language I'm aware of.)

I wonder what the counter point to this is - the regular users who do know and are wondering why you keep telling them what you do? I wonder if a one size fits all email is even a good idea?

Probably need to AB test it.
Great list. I think the reason Mongo has become so popular is because the line it straddles between SQL and NoSQL, specifically the query language. You feel right at home.
