    Disney etc sued over zombie cookie practices 

    CNET reports on a California  suit against Disney, Warner Bros, and some other big pockets. The suit alleges that, on their behalf, Clearspring (famous as the creators of ShareThis) used Flash cookies to re-install deleted http cookies on user’s machines, contravening the Computer Fraud and Abuse Act, California’s Computer Crime law, and that state’s Invasion of Privacy Act. The filers are seeking class action status.

      One comment on the story adds a cautionary note:

      browsers have options to disable third-party cookies, but like http cookies, it removes functionality from websites. now, this all wouldnt be a problem if the user would just clear cookies every time they open or close their browser. which brings us to Local Shared Objects (LSO), better known as flash cookies because right now only Adobe Flash makes use of it. however, when HTML5 becomes standard, H.264 will make use of LSO as well. right now, Adobe doesnt allow flash cookies to read across domains, so for now, we dont have to worry about privacy issues on that front. i very much doubt HTML5 will come with the same guarantee.

    Flash vs html5 h.264 test results 

    As we know Steve Jobs and other Apple execs have recently condemned the Flash plugin as too CPU intensive for use in their products, instead suggesting everyone follow their lead in moving to h.264 playback in html5. Jan Ozer of the Streaming Learning Center has run some comparison tests as to which method uses the most cpu resources.

    Only Safari and Chrome currently support html5 h.264. First thing he found was that as far as Safari in Windows goes that support is imaginary as it doesn’t work.

    On Macs, however, Safari html5 showed marked superiority – 12.39% versus all the competition at 40-50%. On Windows Flash 10 had a slight lead but once he upgraded to Flash 10.1, which takes advantage of hardware acceleration, there were massive CPU savings – in chrome, for example, dropping the load to 6.3%.

    Ozer quotes Anand Lai Shimpi as saying that it’s up to Apple to expose the “hooks” that would allow Flash to exploit hardware acceleration in their products.

    He concludes:

    Apple complaining about Flash being a CPU Hog while not exposing “the appropriate hooks” to enable Adobe to access hardware acceleration seems disingenous at best. To be fair to Apple, though, the iPad related timing was unfortunate, with the bulk of the development work done under the shadow of Flash Player 10.0, which didnt offer hardware acceleration other than full screen on any platform and was clearly less efficient than the HTML5-based approach Apple adopted. Now that Adobe has proven the concept on Windows, perhaps Apple will cooperate with Adobe to make hardware acceleration on the Mac, iPad and future devices happen. If they choose not to, however, they should quit pointing fingers at Flash.

    What else? We also learned that not all HTML5 browsers/H.264 decoders are created equal. Significantly, with Flash 10.1 deployed, Googles HTML5 implementation required the most CPU horsepower of all playback scenarios — by far — on the Windows platform. On the Mac, Firefox and Safari with Flash required less CPU horsepower than Chromes HTML5 implementation.At least from a CPU utilization perspective, Flash isnt BAD and HTML5 isnt GOOD. It all depends upon the platform and implementation

      Arstechnica notes that Jan Ozer has also done a Ogg Theora vs. H.264: head to head comparison

      The new Zune browser is surprisingly good, but not as good as the iPod’s. It works well, but isn’t as fast as Safari, and has a clunkier interface. If you occasionally plan on using the web browser that’s not an issue, but if you’re planning to browse the web alot from your PMP then the iPod’s larger screen and better browser may be important.. I’m currently working on Fishbone Diagram project.
