As far as I know you'd need at least two devices (the one whose screen is displaying the image with the QR code, and the one you're using to snap a photo of it). And then you'd probably want send the decoded URL back to the original device to load in the original browser.
Edit: Maybe you were thinking about the analog world, but watermarked images tend to show up in the digital space (in mockups especially).
Here are the canonical docs: http://dev.w3.org/html5/spec-LC/urls.html#interfaces-for-url...
And here's a prettier (but less detailed) version: http://developers.whatwg.org/urls.html#interfaces-for-url-ma...
Even after allowing for discounted entry fees, the back of
the envelope says the Webbys could be taking in more than
$2 million from its contestants.
There's a service called Tapatalk that does something very similar to what Appifier does, but for forums, and has a number of generated "native forum apps" in the App Store.
Edit, after the parent was edited to include the data attribute example:
You should update your post to clarify that you're talking about data attributes. That's a significant detail and shouldn't have been left out.
Now that you've clarified, jQuery does behave as you've stated, but it's not a bug. I can see how it could be unexpected behavior to some, but it's explicitly stated in the .data() documentation:
Every attempt is made to convert the string to a
JavaScript value (this includes booleans, numbers,
objects, arrays, and null) otherwise it is left as a
string. To retrieve the value's attribute as a string
without any attempt to convert it, use the attr() method.
var foo = $("body");
foo.data("mykey", "1.410");
foo.data("mykey");
Secondly, he says there are "several bug reports on the jQuery website, where people are also confused by this behavior and all of them get closed with a wontfix" but links to none of them. Linking to them should be trivial and they'd help his case (or at least make it easy for me to figure out why he sees a bug and I don't). I searched and couldn't find any.
Finally, you shouldn't use .attr() to store arbitrary data as he recommends. Hanging javascript data off of DOM nodes will cause serious memory leaks if you're not careful. That's the reason .data() exists in the first place.

Specifically I'm looking at the path (small 'p') each icon takes out of and back into the +/x button. When they're close to the button these seem to stack on top of each other more than those in Path, which instead almost follow each other around. Also, something about the "bounce" at the end of the open animation looks a bit different (easiest to see looking at the bottom-most icon).
A nice start though. And I'm sure it looks even better in person than in that demo animated gif.
What they've changed is this: If you subscribe to one of the 3/5/10GB limited data hotspot plans, you'll no longer get unlimited 4G for free.
Yes, things just got a little more expensive for customers with those plans taking advantage of the free 4G clause, but Sprint has not "ditched unlimited plans."
Neither Sprint's notice nor the HN headline was well written.

A few years back I worked for a startup that was cataloging recorded music. I recall that the major labels would provide us with ISRC, among other things, for all of their recordings. I don't recall whether independent labels and artists used it though. I would guess that it varied.
(See also ISWC, which is for the composition, not the recorded performance of it. ISWC/ISRC is a bit like class/instance.)
It struck me as the first time I'd ever heard of an online petition achieving its goal.
Here's hoping this becomes second time.
I use them all the time, and anyone watching over my shoulder always asks what that was. Learn !!, !$, and a few modifiers. You'll be glad you did. Personally, I use !$ constantly (and variations like !-2$, which gets you the last arg from 2 commands ago). The "h" modifier is handy, too. It's like dirname for the word. Consider this example, where you copy a file to some deep path, and then cd to that dir to continue working with the copy:
$ cp foo.txt /some/really/long/destination/bar.txt
$ cd !$:h
$ # (do more with ./bar.txt)
$ echo some args
some args
$ !!:s/some/more
more args
Finally, one really useful thing he doesn't mention at all is brace expansion. For example, these are equivalent:
$ cp foo.conf foo.conf.bak
$ cp foo.conf{,.bak}
The first is that I have a common nickname @gmail.com. There are many other users with some variation on that nickname @gmail.com, and people are careless about typos, including suffixes, etc. It's a similar cause to the article, but the username instead of the domain.
The second case is a more interesting one:
I bought an expired domain.
Now I get all kinds of email sent to what used to be legitimate email addresses of the old domain owners. For more than one of them it was clearly their primary email address. I was getting emails related to bank accounts, Netflix, Facebook, etc. I thought about trying to get in touch with those users, but ultimately decided to bounce their email.
It was something I hadn't considered when buying an expired domain, or about my own email addresses, but it's a real problem. Here's hoping my email provider never lets their domain expire.
They're intentionally ugly. The theory is that an ugly default avatar makes the user more likely to upload their own image.
PHP reserves all function names starting with __ as magical. It is
recommended that you do not use function names with __ in PHP unless you
want some documented magic functionality.
