To be clear, we aren't running some idealistic enterprise where we value standards compliance over real world usefulness. Indeed Opera has historically been more willing to impleme…

> Opera would be great if it handled nonstandard html gracefully for me We put a huge amount of effort into handling "nonstandard" html, including fixing the standards so that they…

Yes, but there is still a node that has an event listener on, and it is quite possible to display that in developer tools. Opera Dragonfly already does this, for example. What's no…

Technically there is still only one "HTML5" standard; the W3C one. WHATWG are editing the "HTML Living Standard". Unlike the W3C model, there aren't version numbers or set phases t…

Oh, so 1:1 between processes and event loops? Doesn't that mean that something blocking in one tab (alert(), sync XHR) might will block tasks in any entirely unrelated tab that jus…

I think multiple "units of related browsing context" [1] would be more accurate; unless I am wrong Chrome uses at most one process per event loop and has one event loop for each se…

OK, GMail drag and drop issue turned into a bug report :)

FWIW we have the "wand" feature which will fill in, and submit, a form for you with previously used values (it's the key icon on the toolbar or ctrl+enter). I know this is not quit…

Random pedantic fact: Martin, and several of the listed contributers work in our office in Linköping, Sweden.

It seems that the "mpt" who owns that domain today and is responsible for this article is not the same as the "mpt" that wrote the original article [1]. [1] https://twitter.com/mpt…

That's what getUserMedia[1] provides [1] http://dev.w3.org/2011/webrtc/editor/getusermedia.html#dom-n...

Opera Next has it (so it will be in the forthcoming Opera 12): http://my.opera.com/ODIN/blog/2012/04/17/web-page-camera-acc... Chrome also has it, behind a flag. (the parent commen…

Do you have a better proposal? The use cases it needs to address are mostly documented at [1] although there are some missing (people are currently putting together a wiki page [2]…

That is a very appealing design, but sadly it doesn't address all the use cases. In particular one thing that people want to be able to do is to display a different image depending…

Because I was making a specific point about the implementation complexity of things that depend on attributes vs things that depend on many elements.

This doesn't modify parsing. Modifying parsing would be something like allowing to have child elements. Adding extra attributes to an element requires no changes to the parser.

From an implementation point of view, putting everything in a single attribute is way simpler; the design of is quite problematic. The reason is that with a single attribute everyt…

Long experience of contacting sites suggests that it is, at best, of limited effectiveness. At Opera we have a not-insubstantial team dedicated to developer outreach who frequently…

It seems like a weird thing to perpetrate a hoax about :) A more reasonable conclusion might be that the author made a mistake when testing Chrome. Having passed on the reports tha…

The DOM and ECMAScript both assume that strings are sequences of UTF-16 codepoints. So while a browser could use non-UTF-16 internally it wouldn't help much because you would have …

Bleach [1] is a sanitizer that uses html5lib on the backend. I think that Mozilla use it. [1] http://pypi.python.org/pypi/bleach

Right, WebKit shipped code based on the spec first but the spec itself underwent subsequent revision as the Gecko / Presto implementors found site compatibility issues and bugs. I …

These "I have X tabs open" comparisons are very unhelpful. Different sites take hugely different amounts of memory in just the same way that different desktop applications do. If y…

http://schema.org/docs/faq.html#14 It seems that they chose Microdata over RDFa because the latter's syntax was deemed to be unwieldy. It's not really true that RDFa is more extens…
