The recordings of all lectures are now available, see above. Lecture 2 is missing because we had technical problems there. To play the Lecturnity recordings (.lpd files) you need the [[http://www.lecturnity.de/de/download/lecturnity-player|Lecturnity Player, which you can download here]]. I put the Camtasia recordings as .avi files, which you can play with any ordinary video player; I would recommend [[http://www.videolan.org/vlc|VLC]].

Hi Alex, can you be more specific about what exactly did not work for you and what you had to do to make it work? In particular, what do you mean by "the server directory"? Do you mean apache's document root? Then where have your files been before? In a subdirectory of the root? And what do you mean by a GET request being turned into an OPTIONS request, and how did you arrive at the conclusion that this is what happens? It should not matter if the .php file is in a different directory than the .js file. My feeling is that your problem lies elsewhere, but it's hard to tell from the information you gave so far.

@whom it may concern: for me the access-rights stuff did not work exactly as in the lecture - i had to move the whole site (.html .js ...) into the server directory. Maybe it's new to firefox 3.5 but i could not access any file on the server from a .js not being in the server directory - it always turned my GET-Requests into OPTIONS-Requests and nothing was returned - so the php-solution does not seem to work, even if my server was able to execute php. Were we supposed to do it like this anyway or is it completely wrong this way?..  '''alex 5Dec09 17:56'''

Ok, the recording of Lecture 7 is now available as AVI. But beware, it's quite big: around 300 MB. '''Hannah 3Dec09 22:46'''

To play the .camrec recording you need the full Camtasia Studio (you can download a 30-day test version if you want). I will soon upload an .avi version instead. '''Hannah 3Dec09 21:56'''

For your reference and convenience, here is a [[attachment:prefix-search.tar|tar archive of the files which we wrote together in Lecture 7 (prefix-search.html, prefix-search.css, prefix-search.js, prefix-search.php)]]. '''Hannah 3Dec09 21:35'''
