This PDF file has the results for the first HTML test (10%) and the second multiple choice test (20%). Grades for the coursework will follow in a week or so. BB1753 ITB.pdf

Here are the feedback sheets for the major piece of coursework on ITB. To find yours, download the PDF and search for your K number (it can be lower or upper case k) BB1753 ITB ALL

This grid shows all the marks in one column (again – by k number only) BB1753 ITB Marks 1112

Please note that grades have not been moderated or passed through an exam board yet, so it is possible that they may change (this is unusual but can happen).

Standards Vs Market

July 3rd, 2009 No comments

An interesting split is occurring inside the group developing the next iteration of HTML.  Many of the individual companies working in the group would like audio and video support (in the style of appropriate codecs that would be embedded inside the browser executable). Reaching agreement on which particular formats should be supported is the problem:

The current situation is as follows:

   Apple refuses to implement Ogg Theora in Quicktime by default (as used
   by Safari), citing lack of hardware support and an uncertain patent
   landscape.

   Google has implemented H.264 and Ogg Theora in Chrome, but cannot
   provide the H.264 codec license to third-party distributors of
   Chromium, and have indicated a belief that Ogg Theora's quality-per-bit
   is not yet suitable for the volume handled by YouTube.

   Opera refuses to implement H.264, citing the obscene cost of the
   relevant patent licenses.

   Mozilla refuses to implement H.264, as they would not be able to obtain
   a license that covers their downstream distributors.

   Microsoft has not commented on their intent to support video at all

However – Mozilla (Firefox) and Google (Chrome) have committed to actually supporting Ogg, despite some questions about the quality that is possible. Will the market simply respond to these by using them? Or will the proliferation of (perceived) freely available codecs mean that nobody cares? It’s well worth looking at some of the astonishing apps built using javascript and an embedded codec to see what’s possible (Ajaxian has great coverage):
