    Safari will strip identical title prefixes in tab names for exactly that case. Perhaps other browsers should copy this.

    CDBaby and tunecore are pretty close I guess, they'll get you on iTunes and more (physical copies too in CDBaby's case)

    Were you using gcc? I wouldn't be surprised if e.g. MSVC didn't perform that optimization since it doesn't have the pure function attribute.

    That isn't hardware decode, that's hardware scaling. http://blogs.adobe.com/penguin.swf/2008/05/flash_uses_the_gp... Also, Flash does not use any of the multiple hardware decode AP…

    You can disable compilation of MPEG codecs if it makes you feel safer. But I don't see what that has to do with my comment.

    Chrome uses FFmpeg, which already has a good amount of ARM optimizations and is around 10% faster than Theorarm on my Cortex-A8. Maybe it's in the same vein as summer of code?

    I think cover.jpg came from doom9 [1] I guess robux4 was talking about the old system, which I honestly didn't know existed before you brought it up. If the new system doesn't use …

    No clue what the depreciated version might be, as far as I know what I linked to hasn't changed since sometime around 2005 (which would explain any broken links.) Cover art wasn't …

    You can't do that in ogg either, you need the header packets.

    Flash has never supported VP7, and the only VP6 on youtube was on self-encoded sponsored channels.

    1. Probably true in that most demuxers don't read matroska tags, but it's standardized (and has been for the past 5 years or so) at http://www.matroska.org/technical/specs/tagging/…

    The 9400 is still active when the 9600 is; you can use both at the same with with OpenCL for instance. And I'd imagine that there's only one video decode ASIC between the two of th…

    The best explanation I've seen is http://www.kaourantin.net/2010/02/core-animation.html when you also realize that for video playback and animation in general, OpenGL > Core Animat…

    Useful error messages. Even in C gcc is lacking, let alone C++, and I'd imagine that fixing this in gcc wouldn't be/have been much easier than writing clang.

    Elliptic curve cryptography and LDPC codes are two that come to mind. Though afaik the latter hasn't really been improved since ~1960 and were only patented after rediscovering the…

    My guess is that the author wasn't the one who encoded either video, and the guy who did didn't know what hinting meant but enabled it anyway when exporting from QuickTime. (hintin…

    Encoding it with a good encoder would require access to the source, which I don't feel like finding if it even exists on the internet. So instead, here's the same file with the jun…

    Technically, ogg, ogm, ogv, and oga all follow RFC 3533 and can legitimately be called the same file format, namely ogg. The only difference between all those extensions the codecs…
