I don't see the advantage in using USB for charging. And a couple of advantages of not using USB. Perhaps using a USB connector was slightly more expensive to manufacture than using standard dc-power connector. More importantly it's probably a lot easier to buy or build a third party power adapter with a standard dc connector than one with a USB male connector. Which is important when selling to countries without easy access to well stocked electronics retailers.
I don't implicitly trust any news organization (not even the BBC) - but there are a handful of journalists who I believe to have extremely high levels of personal integrity and while I might not always agree with their opinions at least I believe that what they are saying is their honestly expressed opinions.

Unfortunately for me only a handful of journalists fall into this category and it has literally taken years (mostly by reading their books) that I identified them.

Unfortunately, that's the pure reality and truth. That's not a single case, for certain. Such things happen almost every day, whenever government people get interest in money you make, you're under a high risk of being under a fake lawsuit, and chances are that you're going to loose everything.
There's no obvious way of changing that, except for the majority of people to raise their voices and start doing stuff to stop corruption. Minority will be simply swiped out and no one will ever know about it.

Selenium might be OK for usability testing a single site, but it's useless for large scale multithreaded crawling and scraping and doesn't scale.

I, for one, would definitely pay good money for an easy library/API to scrape JS-heavy sites without the overhead of a full browser running macros.
Facebook, Relationships And “Catfish”: It’s Complicated
It's very difficult to talk about 'tar' per se. Do you mean:

* GNU tar?

* BSD tar?

* Solaris tar?

Or even Schilly's 'star' program?

Each of these has different limits, advantages, and disadvantages.
But you have no idea if the rich will actually invest that money in the country, and if they'll do it now. Currently it looks like the answer to both of those questions is no.

As for government spending being inefficient, I know that's a common theme, but a lot of studies have shown that it isn't so clear cut. Sure, there are examples where that it is actually true. But most of the time people just use anecdotal experience and the conclusions are wrong.

In the UK, despite everyone complaining of the NHS (the national health service), it actually performs a great job.

As for if it's fair or not to take money away from the rich to give it to the poor, personally I think it is. Not because I want a communist society (far from it, I think communism has no basis in reality) but because of the old saying: "It needs money to make money". For example...

A rich family has already covered all their primary needs with their 20%, and with another 30% they cover the less important stuff. Since they have no use for the rest so far, they may either invest it or put it in a bank. Hopefully they'll get extra revenue from it which they can invest again, and so on.

The poor family, instead spends 100% just to pay for primary needs and a few non-essential goods. They are not left with anything to invest. If the want to get a new house or start a business they need to borrow money. That's basically saying that the poor get taxed for trying to get a house or start a business, so compare to those who are rich they need to earn more from that business for the net revenue to be positive.

But even if you don't think it's fair, it still helps the rich to give money to the poor, though only in the long run. A lot of poverty means more criminality. A lot of sick people means higher chances of contagious diseases. The rich gets a benefit from making sure that the poor are not too poor.

But anyway, these last two points are personal, and I understand if you don't agree. In either case I still think that giving money to the poor in an economy downturn is good to start up an economy where people are weary of investing.
Actually, I have someone who did think that about parentheses - we'd have arguments about which approach was clearer. We never did agree.

Looking to set up "startup apartment" in San Francisco
I just raised a $1m seed round for my startup (enterprise collaboration), and am looking for people founding or working at startups to live with in San Francisco starting around October 1st.

Why people involved with startups? Because I think that there will be a level of mutual understanding and support, and I'd like to have a social apartment setting where people of all types are welcome. I'm looking to keep a nice, clean, comfortable place to live, and am probably looking in price ranges that are poorly suited for bootstrappers (my guess is $1200-1600 per person).

Probably looking for a 3-4 bedroom. Email SFStartupRoommates@gmail.com if you're interested.
I'm not sure how you can be biased toward something without being biased against everything else, but the spirit of your meaning seems true. YC companies and submitters have an institutional advantage, but I am not with a YC company and don't feel discriminated against.
Wouldn't sleeping with the curtains open achieve much the same thing?

From the article there doesn't seem to be much special about camping other than it removes much of the artificial control we exert over our environment (light, noise and so on). Just willingly stopping those things would be a big step in moving back into a rhythm which was more in step with the natural day / night cycle.
I think that depends on how sophisticated a service is. I agree that applying some regular expressions to emails is not enough to make any other company buy you instead of building it themselves. But that holds for almost anything a startup can do.

Startups need to solve difficult problems or they are nothing more than marketing firms trying to create a hype around hot air. Filtering email intelligently, including automatic anonymization of sensitive parts within the email, can be a difficult problem to solve, and I think there are many types of email integration that a startup could tackle based on the approach Matt suggests.
..one of the problems of my generation is that too few of us follow our hearts.

Is this really specific to our generation?

For that matter, I don't know what generation you're from. I assume the same one that I'm considered to be, if you're talking about a recent graduation. But, you could be older -- attending someone else's graduation.
Over the years, I've occasionally heard of people getting kickbanned from HN. It doesn't happen that often, but when it does, it's been because of egregious trolling, spamming, etc... I've also heard of one or two voting rings that got booted as well.

It doesn't happen too often, however. The community here usually has pretty high commenting standards, and there's peer pressure that encourages good behavior.

One thing which I think would help many programmers reset their sleep schedule is to remove routine use of caffeine.

For me it was only giving up caffeine that made me realise how powerful a stimulant it actually is. If you're in a daily routine in which you're routinely and regularly drinking caffeine throughout the day then it's almost certain that it is impacting your sleep cycle. If you're drinking caffeine in the evening and still sleeping at night you're probably exhausted or at least over tired.

I'd recommend to anyone cutting it out for 2 - 3 weeks just to understand it and allow you to better work out how you want to use that effect. For me that means first thing in the morning and as needed (I have a 15 month old daughter - that can be fairly often) but never in the evening and rarely in the afternoon.

Certainly if you wanted to reboot your sleep schedule I think stopping it would be significant. If nothing else then for a heavy coffee drinker the added tiredness caused by removing the additional stimulation would help you sleep earlier.

More on the impact of caffeine on sleep and sleep in general in Counting Sheep by Paul Martin (http://www.amazon.com/Counting-Sheep-Science-Pleasures-Dream...). It's a bit long and in places but it's worth reading despite that if you're interesting in understanding sleep.

The Glut of Shows Unwatched
For me, while I had often heard and used "faze" in conversation, I seldom saw it in writing. Early on my mind got comfortable with the bogus idea that it shared etymology with "phase", and so I assumed they were spelled the same.
Personally I don't agree with the post, starting from his analysis, of the first snippet of code:

group->text = (char *) malloc(sizeof(char) * strlen(params->text));
if (group->text == NULL) {
res = MP_MEM;
}
strcpy(group->text, params->text);

I don't think that the sizeof(char) or the casting of the pointer are of any danger and increase readability (we are not coding to show how well we know the standard).

The poster is right about the missing space in the malloc call for the NULL char, but I see a bigger threat calling a malloc with the size coming from a strlen: it can be really dangerous if somehow you miss a NULL terminator.

And again, same complain about the usage of strcpy. The standard gives us strncpy that put a limiting size in the copy operation.

_Personally I think that strcpy has to be avoided as a plague being a source of buffer overruns error as no other call in the C library._
I agree don't use IP as a part of token - it will require user to re-authenticate very often.

Marak, the guy behind the Nodejitsu (and, presumably, the popup message) is known to exhibit asshole behaviour. (See: http://news.ycombinator.com/item?id=1448309) The popup message is consistent with what HN knows of him.

Whether being a jerk justifies banning I can't say - but his assertion that HN is biased has little justification (particularly when you consider that the writer himself is biased.) Kindly ignore.
"brain scans" depict no such thing. "10% activation in the brain" is probably a meaningless statement -- the brain is always doing "something" (except when it's dead), and in any case, there's lots of different ways it might be getting "activated" (e.g., learning v.s. doing). That said, it's certainly possible to be mentally lazy, and this would no doubt lead to different patterns of activity than being mentally vigorous.

Usually what these brain scans depict is, more or less, how "different" (brighter usually means larger statistical significance t-values) the oxygen-usage activity of some test state is from the same oxygen-usage activity during some rest state. Google fMRI (or look here: http://www.scholarpedia.org/article/fMRI).

Sometimes this means "less" activity than at rest state. Sometimes this means only very slightly (but consistently) more. Moreover, parts of the brain that vary considerably from trial to trial, but average out to a negligible difference from rest state, would also be easily ignored. This should give some sense of just how many assumptions and calculations have gone in to the pretty brain heat maps that the media are so fond of.

Lots of good and interesting stuff can be and has been figured out using fMRI. That said, figuring out how the brain works using fMRI is like trying to figure out how an economy works by observing CO2 emissions from space, at a resolution of, say, 10m.
There are some individuals that are either around for a while, or just getting started, and for whatever arbitrary reason one day all of their comments and submissions will be auto-dead.

They of course aren't notified at all, so they're quite happy to keep adding comments to the site, all of which stay at 1 point and never get replied to (or even read by anyone except those with showdead on).

Since there's no messaging system on this site, if they haven't bothered to add any contact information to their userpage then there's no way to let them know.

I occasionally see these folks posting some pretty thoughtful comments while auto-dead, too.

However, this has been a subject of discussion here a few times, and nothing has changed; I don't expect it to.

I do expect that this site will be banned soon too.
This is a great sentence which sums up the sort of things that many self help books will drag out to 400+ pages.

I'd seriously encourage anyone who wants to improve their life to spend the time sat down with a pad scribbling out what they're happy with about their lives, what they're not happy with, what they want to change and coming up with their own plan for doing so.

For the most part anyone on this board is smart and more able to solve their own problems than a generic self help book which will generally take a couple of bits of common sense and then string them out into a whole book.

Don't get me wrong, I love books and I love reading but in the case of self help books I think more often than not they're targeted procrastination and the time would be better spent addressing the things you're not happy with.

I mostly agree with this. While I don't think we should increase mining profit taxes, I do think some of the mineral wealth should be locked away into a sovereign wealth fund - the type that can't be gotten at by sticky fingered politicians of any persuasion. The wealth fund could be used for apolitical purposes, like education funding (scholarships?), national dual lane freeway construction, large-scale water projects. But only after it reached critical mass and was throwing off a couple of billion per year in investment returns.

Your local laws are the ones that you could potentially be held accountable to.

MailChimp is American, Campaign Monitor is Australia. They are subject to the laws of their lands.

He seems to be about the same sort of asshole as a lot of other internet personalities (Theo comes to mind). i.e., he's good at what he does, knowledgeable, and he doesn't take the time to play nice with others.

It kinda comes down to what sort of "thing" HN is supposed to be -- whether it has a place for people like him -- but regardless, he's certainly not exactly hurting over his inability to play in our little sandbox here.
So, Craigslist is getting mischaracterized and demonized the same way that Google is. I'm tired of people lamenting these sorts of shenanigans. I'd like to hear recommendations as to what we can do to mitigate the bullshit.

Which is actually pretty useful and readable, imho (if formatted correctly):

return a ? b :
c ? d :
e ? f :
g;

Side note: this does not work in PHP, as the operator is left-associative instead of right-associative there. The above in PHP would be evaluated as:

return ((a ? b : c) ? d : e) ? f : g;

Which is almost never what you want. I can't even format this properly to convey intent.

Two Surpising Things about R
Perhaps, though I wouldn't put it past him to write that popup message. It reads as childish sniping, is unnecessarily snarky, and it detracts from the core message of the post.

Knowledgeable he may be, but professional he is most certainly not.

Edit: I must admit, however, that I'm interested as to why he was banned. I don't believe he's said/done anything spiteful and mean in HN itself.
They're not necessarily required to be connected, but as a historical matter there's some overlap, especially in the late 19th and early 20th centuries. One strain is a certain kind of social progressivism, which sought to clean up social ills: abolish slavery, abolish drunkenness, achieve equality, improve literacy, etc. So a bunch of the early suffragettes were also active in the temperance and abolitionist movements, among other things. From a different angle, there was also a perceived connection with domestic violence (since most alcoholics were men). Prohibitionism isn't really mainstream anymore, and abolitionism has thankfully become irrelevant thanks to its total victory, but some vestiges of that coalition remain in the anti-porn feminists (though that's very controversial even among feminists; there are probably at least as many "sex-positive feminists", esp. among younger women).

It's not just you. Political correctness, 'showing both sides of the debate' and editorializing have made the news far worse than it ever was in recent years. We urgently need news that delivers the facts, and only the facts. Maybe some distributed yet structured collaborative effort like Wikipedia for news?
Whenever I want to feel good about the world, I look at things from the perspective of the entire history of the human race.

Thousands of years ago, most of our ancestors were more likely than not subsistence farming or, if they were doing anything historically interesting at all, laboring on gigantic walls or pyramids or other largely useless monuments for various kings and tyrants. There was no choice as to what one did with one's life, it was dictated by the circumstances of birth.

Even having dreams, much less the ability to follow them, is a rare thing for humans. We're each blessed to have this ability.

I just saw this popup after following a link to nodejitsu from HN, how much of his claims are true?

hello, i see you are coming from hacker news.

the article you clicked on was most certainly not submitted by nodejitsu.

news.ycombinator has a long history of squashing articles and submitters that aren't funded by y-comb.

most of this is done through their "silent" banning and censoring mechanisms, that leave people not even realizing they have been silenced.

i hope you enjoy this article, and remember that HN is extremely biased and that you should keep your horizons broad.

> It's called instinct, sometimes, taste, other times, experience by yet others.

None of those are 'understanding'.

> Do you think the experienced cook can necessarily explain exactly why some things work and others don't?

No, which means he doesn't understand what he's doing, merely that he's built up empirical knowledge about what works and what doesn't.

He can teach that knowledge to someone else but that's just transferring the 'ritual', not the underlying knowledge.

Don't underestimate all of the cooks though, some of them are quite knowledgeable when it comes to the underlying chemistry and the theories of taste and smell.

I doubt that HN censors people they disagree with. I've written many things that one could say are anti YC or anti-YC companies, and I have never been censored or had anyone email me telling to not do this. Several other people also who say 'anti-YC' things have been active on this site for years.
