That is exactly how they should be used: to give more detail once the user decides they want/need that detail.

They are used all over the place in Japan (where IIRC the QR code's popularity started) for non-sales related information like bus timetables as well as for access to detailed product information in shops. In both these use cases the QR code directing to a web page with up-to-date information is a benefit to the user rather than an advertising gimmick.

QR codes are done wrong in a great many adverts.

I've seen adverts with QR codes where is isn't entirely obvious what is even being advertised: sorry, I'm not wasting my time waiting for your information to come down what could be a slow mobile connection unless there is a good chance I'm going to care. You advert should make me want more detail, not expect me to make an effort to get basic detail.

The two times I bothered scan a QR code on an advert were failures from the advertisers PoV. One went to a page that was simply not useable on a small mobile device (remember: there are plenty of phones out there with QVGA screens and that site was unusable at half VGA) and would have taken an age to download if the user was stuck on a GPRS link due to lack of 3G+ reception. I closed the browser and thought nothing more of it. The other time I was taken to a registration page where I was asked for some of my details in order to get the data - if I scan a QR code I expect to go direct to relevant information, not to be asked for my personal details (I could have oput in fake details easily, but I should not have to go to even that effort). If you must have a registration form on the page, put it below the detail the user is expecting to find.

I think in general people in this thread are missing an interesting facet of this solution. Suppose that the inventory system was also a POS system (which it'd probably have to be in reality), there's opportunity there for lots of analytics that a brick and mortar store just doesn't get. And, there's even the opportunity of integrating deals for loyal customers, etc, etc.

The company providing the service could also get access to shopping records of individuals at various brick and mortars--something that probably doesn't exist, which could lead to targeted advertising on receipts (which the shop owners could take a cut of, for instance). There's lots of ways that all parties involved could benefit without killing the small businesses.

Personally I'd look at going to networking events and checking out mailing lists for co-working spaces. I'll give a spin and a mention to the people I know.

Anyone knows how the cover keyboard is built ? is this a 'fake' dumb plastic molded keyboard using a capacitive layer underneath ? I wish it is, so that the whole keyboard could be an analog sensing surface if needed.
It happens sometimes. I had written a multithreaded parser in C++ to parse around 800MB per day so another team could build up the rest of the project based on the data. Someone had thought it'd be a better idea to store all fetched data in XML.

Role of a Linux Kernel Maintainer
They never learn... Some time ago (early/mid 90s I think) there was a particular problem with pickpockets in the Kings Cross area so an awareness campaign was started with similar posters. The problem got worse. Why? Often people walking past the posters would, consciously or otherwise, check the pockets their wallet or other valuables were in - this helped improve an observant pick-pocket's hit rate.

It covers Django 1.0 which is pretty much old.
I recently picked up "Practical Django Projects". This book is for Django 1.1.

I am frustrated with the code samples as of now. So much code change when you compare pre 1.4 and 1.1

@iman453 I dont recommend buying any Django books if you want to learn Django version 1.4.

But if you really need a book, then go for the www.djangobook.com which is free.
Make something amazing with the web
You seem to be spot on. Major outlets and retailers, like you say, already compete on items for penny differences. Nobody is going to look up on their phone that they could buy Granola bars for $.05 cheaper at Walmart than at Wegmans.
The purpose of this app is convenience, however there seems to be little point to it if the concept itself is flawed for the reasons you've just stated.
The system behind the app should be both. When you think of yet another groupon, you jump a little to short IMHO. But if you add POS, inventory management and a unified sales / distribution channel and provide that to local stores and shops you'l get quite a product.

But can't I stop to think of pg's frightening ambitious start-up ideas here? The odds are certainly against you, but the rewards will be equal if manage to pull that one of.
I think it's a little early in the game to be making statements like that.

Also, if you're unfamiliar with CSS generally, the 'conventional' approach (as opposed to img tags in markup, or characters in an icon font) would be to use a sprite. This is also advantageous from a frontend performance standpoint as you avoid additional network overhead in getting individual graphics down to the client.
One solution to the lack of pushState is to just offer the non-JS version of your website to such old browsers. Easiest way to do that is to have the JS bits disable themselves if pushState isn't found.
Well some reports yesterday considered this as sort of a reference design but MS showed how good they can be at hardware. I can't imagine anyone not wanting to choose the Surface first over an OEM unless it's due to price.

I think it also shows the internal conflict of MS. Ballmer spoke of the integration between hardware and software much like Apple has done. We may be seeing the beginning of the end of the OEM on a large level such as a Dell and HP.
Well, I don't think QR codes are inherently offensive, and if some people use them, why not? I would only say that it's a bad idea if the only point of ref on it is a QR code, but if a typed out website name is included, what could it hurt? I'm also solely talking about QR codes in advertising.

This is the one thing we have come to accept with hosts. For us now it is a case of how easy it is to keep those servers up if things do go wrong.

Why reject tiny donations? Why not just stock them up and then send multiple donations in a single transaction?
Great article - upvoted. That it's inconceivable that the US or UK government could think about spending such an amount (~5% of GDP!) on a long-term science and engineering project speaks volumes about why the Germans are where they are, and why we're where we are, economically speaking.

From an engineering point of view I think it's foolish to turn off the nuke plants, but public opinion is what it is, and this causes the regulatory requirements to prevent nuclear from being economically viable.

The article does a good job of covering the risks, but personally I'd bet on the Germans here - even if the 'Energiewende' doesn't pay off per se, the rewards from the science and engineering knowhow will be huge. The only comparable project I can think of is the Apollo Program, though a quick google suggests that was never more than 1% of GDP, and the returns from the science on that were massive and lasted for decades. Likewise, CERN, which was about as blue-sky as things get, gave us the World Wide Web: completely tangential to its stated purpose, but what kind of rate of return did that give us?

So here's a question for the peanut gallery: has there ever been a large-scale public investment program into science and engineering (that ISN'T based on destroying things in new and exciting ways) that has not proved to be a good investment in the long run?

(On a side note, I really want to have a stickybeak around a 30MW AC/DC converter!)

Specifically, the IBM PC.
I'm confused by their description of templates as "messy" and their decision to use laconic. Not an opinion that I think is widely held and definitely doesn't make sense to me. (by html templates do they specifically mean ejs/erb type templates versus jade/haml??)

Using html templates is good separation of concerns and js just isn't very good at expressing html structure. Jade would have been a much better choice IMO. Laconic does a good job of minimizing the problems with using js to programatically build dom in js but still doesn't come close to a proper templating language.
I don't like this. Instead of heavily subsidizing some technologies, they should tax externalities (i.e. pollution) and let the markets do the rest. It's annoying having to pay 15% more energy bills because somebody has decided that wind and solar are the hot thing of the moment.

Bad, really bad. Same way of thinking that brought us to the debt crisi in Europe.

Stephan Reimelt, CEO of GE Energy Germany: "Germany is forcing itself toward innovation. What this generates is a large industrial laboratory at a size which has never been done before. We will have to try a lot of different technologies to get there."

It has been done before, at far greater scale. WW1 and WW2. Some of the best innovations or inventions are derived out of a person or a nation having their back to the wall. Hence the famous saying: "necessity, who is the mother of invention" (dating back a mere 2400 years or so, and it's probably older as a known premise).

I would anticipate very impressive industrial breakthroughs in renewable energy coming from the German experiment.

Good point, but why label those as "attempts"? A decade ago PDAs were pretty good devices with decent amount of free apps and an interesting range of possibilities. (For one, they were extensible via cards. Something that's not available in today smartphones I know of.) You could read books, play games, use internet via WiFi, plus there was a lot of business applications for them. Heck, my old Asus MyPal has better book reader and calendar apps than I have on my current smartphone.

Sure, there wasn't a marketing hysteria around PDAs, but they were a viable market of their own.

Tablet laptops were used by many people as well.
Hmm...I did not know that! I should really have said 'eg.' instead of 'ie.'

The point of the above 'timestamp' is is to represent a specific instant in time, independent of any time zone or calendar system. You can use Unix time for this purpose.
