I suggest the title should say "Polychlorinated Biphenyls cause birds to sing a different tune".

In the context of Hacker News, the title suggested to me that someone had engineered a Printed Circuit Board that would interfere with birds' brains, perhaps by emitting magnetic fields to mess with their sense of north, or something.
I'm not sure if you are meaning to have this place flooded with fake comments, but don't do that if it is intentional. We can see which users are very new.

Also, likeastore looks kinda neat, but you shouldn't be blocking any symbols from passwords. I'm wary to sign up because if you are scanning the password for "not allowed symbols" then you are probably not saving the password the right way in the database.
Arrogant? All I did was graph long term data and present it, observing that people freak when it shows something other than what their doctrine insists.

Sure I expect those scientists are familiar with the timeframe I present. Then why don't they present it? Why no comments on the non-warming of the last decade? If 20M years of CO2 data, then why no graphs showing correlation with temps? (BTW, CO2 lags temp.) How about that massive arctic ice sheet growing now growing well beyond normal reach? And ya gotta admit the frequency of global warming conferences getting snowed out is just funny.
I wow, that's a great idea. Thanks!
I read this as "no, it wouldn't show up".

"Had there been such a global warming before, it would very likely have registered clearly in some of these data series, even if it didn’t show up in the averaged Marcott curve."

I'm not arguing their conclusions. I'm criticizing the way they present this data. This composite reconstruction is so weak, that if you shifted 20th century AGW back 5,000 years, it would completely erase it. That's how powerful the smoothing is.

You specify that the place s is const, not the value it keeps. You can still do:

#include <string>
#include <iostream>

// not your code
void innocentF(std::string const& s) {
(const_cast<std::string&>(s)) += std::string(" I'm evil.");
}

// your code
int main() {
std::string const s("hello world.");
innocentF(s);
std::cout << s << std::endl; // hello world. I'm evil.
return 0;
}
Nobody denies that W3Schools is a terrible place to learn how to program. Their examples are outdated, insecure, and don't really explain why things work in a certain way. Their tutorials are optimized for copy & paste, and God knows how many security bugs in the wild are due to somebody copying W3Schools.

But W3Schools also carries some of the most easy-to-use indexes of pretty much everything related to web development. Can't remember the exact name of that CSS property and its possible values? Can't remember the order of arguments of a JS string/array function? Go to W3Schools and browse their lists, get the answer in 5 seconds.

Of course, there's Mozilla Developer Networks, too. But MDN's CSS Reference [1] is just an alphabetical list of CSS properties with no explanation. W3Schools' CSS Reference [2] is neatly categorized, and each entry has a short explanation next to it. Very useful when you're trying to remember, for example, "word-wrap: break-word", which is not the same as "word-break: break-all".

[1] https://developer.mozilla.org/en-US/docs/Web/CSS/Reference

[2] http://www.w3schools.com/cssref/default.asp

W3Schools is good ol' Web 1.0 stuff. Just some lists and a bunch of links. No need to ask somebody and wait for an answer. No need to watch any annoying videos. No need to follow an animated tutorial designed by someone who thinks they know how a person should learn programming. W3Schools is like an old dictionary. A dictionary isn't particularly helpful when you're trying to learn a foreign language properly, but it's quite handy when you're face to face with a foreigner and you need to think up a word for "toilet paper" quickly.

I use W3Schools when I need to remember something quickly, and MDN when I need to learn more deeply about it. When I write CSS, I always keep W3Schools open in one tab and MDN in another tab. I wish somebody would link W3Schools' lists to MDN's details. That would make the best of both worlds.

If I understand correctly, this billion dollars is a writedown in inventory and not cash. It's for product that's only been in the channel for a few months. Good product like the Z10.

Why? This lowers the price of the corporation so it can be taken private. They are making BlackBerry as affordable as they can, as quickly as they can.

I have a Q10 and I love it. I had a Z10 and I wish I still had it. Great smartphones with the best OS I've ever used. And just recently they announced the "flagship" Z30 to get users excited: http://www.techcentral.co.za/meet-blackberrys-new-flagship-t...

BlackBerry will be around for a long time, but they will be leaner, wiser and with a genuinely great product line for the future.

What's with the formatting on android - the right hand margin is off the screen and I cannot pinch to zoom out?
My background: In my free time, I teach web development to complete beginners, for the SF GirlDevelopIt chapter (using http://www.teaching-materials.org/).
A few observations I've made:

1) For the sort of things that they are trying to learn (basic HTML tags), W3Schools is a great resource. It's clear and fairly up to date. No other resource has managed to overtake them for beginner friendliness. I was hoping http://docs.webplatform.org/wiki/Main_Page might, but right now it seems like just a skin over MDN and searching doesn't work so well. I don't know if they've given up or what. (One idea: You could help them)

2) After I teach the second HTML lesson, I will explicitly show students "okay, here's how you search for HTML help on the internet." At that point, I'll show them W3Schools and MDN and explain the drawbacks/benefits of each. Don't know how much of that sticks with them, but it's worth a shot.

3) It took me a long time to put together HTML/CSS/JS curriculum. I first started several years ago, when teaching our first workshop, and have been adding to it since (and there are still more topics I want to add). I did also start video taping my lectures, as I figured it could be a resource for people who didn't make it to the workshops, and that also took me a long time - about an hour to record and edit a 10 minute video. So, I support anyone putting out more great knowledge material in the world, I just hope you have a fair amount of time allocated to work on this, so that you can it proper justice.

4) I recommend having a test audience for your material, like somebody that you tutor, so you can see how they respond to it and where their knowledge holes are. Also, a feedback button. :-)

Stop banking with big banks. Go local. When my brother started his business, he moved all his banking to a local bank, one that had only one branch, which was downtown in his town. He's built a personal relationship with them, and the flexibility it's given him has paid off in spades over the year.

There's no reason to pay some megacorporation to treat you impersonally.

I really love MDN, and in some ways I feel guilty for doing this. I've been a MDN contributor.

But the MDN information architecture/navigation is terrible, the crowd sourced content is inconsistent, the pages load very slowly. When you put it all together, it's difficult to focus on winning the search engine game with those flaws.

There was a "Better JS docs" movement a few years ago that moved the needle a little, but in the end it was just the wrong content to do the job.

I thought this article was fascinating and made me think about all of this stuff in a completely new way.

I'm much like the author. I bank electronically. I actually just visited a physical branch today for the first time in months because I had a big wad of cash to deposit, and mobile phone deposit technology hasn't quite reached the level of sophistication needed to handle cash yet.

My relationship with my bank is generally simple. They store my money, and occasionally pay it out or receive more. This is almost all automatic. The one thing they do that might actually involve some effort is the bill pay service, where they will actually mail a physical check in some cases. But most of the payees I have set up in their system have electronic arrangements.

When I need further service, they're good about it. They answer their phones quickly, they can overnight a cashier's check for a reasonable fee on the rare occasions I need something like that, and they'll call me if something looks like fraudulent activity. But this comes up once a year or less.

For the most part, they're basically another appliance for me. We have defined roles and we stick to them. I keep a generous pad of extra cash in the account, never overdraw, never need anything weird, and in exchange, they charge me no fees, even pay me (extremely nominal) interest, and don't hassle me.

This works great if you have the responsibility and cash to do it, but it would fall apart if I didn't. If I started cashing bad checks and overdrafting, I'd get hit with fees up the wazoo and I'd pretty much have to leave. Features that are an extreme convenience to me now, like totally automatic bill pay, would become a huge liability.

I looked at these places and thought that they offered less service. They don't even keep your money for you, after all! And they charge you for the privilege! But, to their customers, they offer more service. They offer more control over their customers' money. They offer more flexibility and less punishment when bending or breaking the rules.

It's a good lesson in not just assuming people are dumb or ignorant. Sure, a lot of people are, but when behavior is this common, there's usually a good, rational reason behind it.

I always thought that if I was poor, I'd still be "smart enough" to bank properly with whatever money I had. Now, I wonder if that really would be "smart".

I also wonder about financial regulation. I generally favor a "better safe than sorry" approach there, but this might illustrate a downside of that. We've all heard about the trouble that non-traditional companies have had with such regulations, whether it's companies like Paypal, or Simple, or Bitcoin-related businesses. They try to get around the regulations in various ways. Here, RiteCheck is getting around banking regulations by simply not being a bank. I have to wonder if they could offer better service and some of the sort of safety and savings ability we associate with normal banking if it were less difficult for RiteCheck to offer something like an actual bank account.
An example that doesn't have a cost penalty is to watch how people merge lanes on a multi-lane highway, some people merge as soon as they see a roadsign, some at the last possible point.

Feedback:

1) Excellent site look and feel.

2) Juvenile language and problem statement. Off putting pitch to developers that found W3Schools useful. At some point it'll have to switch to a more professional approach.

3) Reading between the lines, apparently the author's goal is to crowdsource basic tutorial development with a long term for profit motive involving premium content. While transparent to mention this up front, it leaves me uninterested in participation.
> Many banks over the last century have run out of money and been unable to honour withdrawal demands/requests. It's reasonable and logical not to trust them to keep your money and give it to you when you ask.

Within the last century, yes, but quite far back within it: the last time anyone with modest amounts of money in the U.S. lost deposits in a bank failure was 1933, the year the FDIC was created.

You can still lose money in a bank failure if your deposits are above the FDIC insurance limits, but poor people by definition would not have that much money, so it wouldn't explain their choice not to use banks.

Cost. If I bank with a large bank I can use their network of ATMs for free. With a smaller bank I can't withdraw anywhere other than my branch without incurring a ridiculous $3-$5 charge.
Web Performance Heuristics
Can the public understand that?

Excluding math, we use proxies for just about all science. With different assumptions and different criteria. I don't deny that there are politics, assumptions and margins of error but they do put effort in to minimizing them and doing real science. Take a look at pharmaceuticals, they don't even know why a lot of medicine works, in fact there is debate on if it even does... But people still buy it and take it.
Well, that's not quite true. There is always a small risk of losing some (or even all) of your money, particularly if you have a large amount in your account. Obviously that risk is very, very low for smaller amounts of money.

They don't really have to. Put up a storefront on the web like every other 21st century company and let people download mp3s and flacs and they're good to go.

A simple mp3->iDevice utility is all it would take to simplify importing onto a device and even better you should just be able to cloudplay purchased iTunes songs on your iDevice and/or download/push to the device directly.

iTunes serves almost no purpose in a modern world.
Currently, I'm interning at a well known banking wealth management company, and I find the rich like to have the same environment.

Birthday cards, get well soon cards, calling the client and asking how they are, helping them with last minute account stuff (like making their visa have a higher cap so that cruise trip can be insured).

I think a lot of banking should be like this. I doubt it ever could be, as most banks have very few people, but specialized areas, like this rite-aid, or some wealth banking, have the time to dedicate to these people.

Treating people like people, whether it is restaurants, or banking, or anything, makes a business less like a service and more like an experience. It should be something a lot of startup companies on hn should look into.

Not all US ghost towns are are dramatically smaller. There seem to be many with peak population in the (low) tens of thousands.

- http://finance.yahoo.com/news/american-ghost-towns-21st-cent...

And while I agree with you that they weren't unoccupied to begin with, unlike the case with many of China's ghost cities, I beg to disagree on the rest of your argument - namely that the US model was appropriate for its time (we have decades of hindsight) and that the Chinese model isn't appropriate for the present (we don't know).

Many experts have been prophesying a crash for China's investment driven economy for years now, and a dramatic correction in real estate prices. Yet, after a small correction prices are still rising - http://www.economist.com/news/china/21577118-soaring-house-p...

We may only know a decade or two later whether a few dozen ghost cities was a small price China paid for continuing to power ahead economically.
Mistrust of banks' ability to honour withdrawal requests is largely irrational in a developed country given the existence of government-backed deposit insurance (and the much greater risk of having your cash stolen). I'd actually consider this to be the classic example of irrational mistrust based on a limited understanding of who actually loses out as a result of bank failures, and overconfidence in one's ability to keep hold of their cash.

The inconvenience argument might be true for some[1] people in some countries but is a complete non-starter in my country where retail bank accounts with a positive balance usually are usually fee-free, as are most forms of transfer between domestic bank accounts, most debit card payments and cash withdrawals from most ATMs. It's hideously inconvenient not to take advantage of all that
([1] I understand that somewhere like the US depositors' costs from basic use of the banking system might sometimes be even higher than those levied by non-bank financial service providers they use instead...)

Granted, the moral conflicts argument has a bit more standing, but arguably only if you apply the same standard of scrutiny to other entities you choose to purchase goods and services from (most of whom will deposit your payment in a bank account...). It's not like there aren't banking service providers that have at least seen the marketing benefits of an ethical stance

Many credit unions are part of a large co-op with lots of no-fee ATMs all over the place ( http://co-opatm.org/ ). You can also deposit checks/cash at many of these ATMs. They may not be on every street corner like major banks are in some cities, but chances are there's one near you. Some of those credit unions will also reimburse all your ATM fees if you use your debit card a certain amount (for mine, it's 12 transactions per month).

Members of W3C have asked W3schools to make it clear that there's no link between W3C and W3Schools, but W3Schools declined.

W3Schools offer "certification" - (http://www.w3schools.com/cert/default.asp) - of dubious value. This is troublesome because people know of W3schools, and sometimes think there's a link between W3schools and W3C.
Throwing my hat into the ring here:

1) I think that we, as the human population, should actively move toward more efficient, less destructive industry on principle, not just because of the threat of climate change. I think making it about climate change gives too many opportunities for argument derailment. Think about when "tree hugger" was a pejorative term; i mean, who DOESN'T want to hug a tree? I think it's a lot harder for people to argue against the idea of "leave a place as you found it" than to find flaws a data set. It also allows for much broader regulation. For example, we could then start focusing on legislation against pharm manufacturers allowing meds to seep into the water supply rather than just the air pollution they're producing.

2) I'm starting to wonder why we're not focusing more on adaptation to than prevention of climate change. I've been watching a lot of TED talks lately (thanks, Netflix!) about the impact of climate change, and the one that I'm thinking of was a researcher who spent time in the arctic studying the wildlife there, and made the case that we should prevent climate change so that we can save arctic wildlife. But I wonder, if we were alive in the age of dinosaurs, would we be saying that we need to clean up the atmosphere to prevent the impact winter that would inevitably kill them? While I love wildlife, I almost feel like it's not our responsibility as humans to tamper with natural processes like extinction. In our prevention efforts, we may also be preventing natural selection and, by extension, adaptation. It could be a reality that we'll face an extinction event that wipes out all other non-domesticated mammalian life. While we can all agree that an Earth like that would suck, we know that, 600 million years from now, EVERYTHING will be wiped out. People speculate that, at this time, humans themselves will either become extinct or will have migrated off the planet. So, my question is, are we prepared to jump ship if Earth becomes uninhabitable? Is it realistic to try to change all 5,000,000,000,000,000,000 kilograms of atmosphere, or should we starting thinking about building habitats for space living?
