Small nit: the website uses a <video> element and only provides an Ogg Theora video. This means that the video isn't visible in Safari on OS X and iOS, or in Internet Explorer on Windows. In Safari on OS X this results in an empt

As of OS X 10.9.2 and iOS 7.1 the setting has been removed and autocomplete=off is always ignored.

Safari in 10.9.2 ignores autocomplete=off. The preference was removed since it's no longer of any use.

Can you clarify what part of my comment this is in response to? I'm having difficulty understanding why you chose to post it in reply to my comment.

Yes, this only works if you have Mavericks. It is called Safari Push Notifications because it's a push notification feature provided by Safari, to distinguish it from OS X's more general support for push notifications. Safari also

WebKit makes relatively heavy use of reference counted objects, though a custom reference counting implementation is used rather than std::shared_ptr. That said, there has been an increasing emphasis on preferring unique ownership to shared

OS X provides the POSIX_SPAWN_CLOEXEC_DEFAULT flag to posix_spawn, which results in it automatically closing all file descriptors that aren't described by the file actions passed to posix_spawn.

Thanks for the pointer on running the tests. I noticed two big issues: 1. Some of the tests use shell functions like "read" that jsc doesn't provide. This is easy enough to address. 2. I was mistaken about the quality of the

From what I can tell, JavaScriptCore has had typed array support since at least as far back as December 2011 ( http://trac.webkit.org/r103637 , a random change in JavaScriptCore involving typed arrays).
