A Speech On The Linux Kernel Preemption Patch
Topic of this speech is the kernel preemption patch...
Apart from the original Keynote version I did exports to some other file formats as Keynote is not really available for many platforms (i.e. only for Mac OS X). Unfortunately all these exports suffer from various losses, therefore I comment on the drawbacks of each exported file.

Although I used Apple's Keynote to create the slides of this presentation please do not understand this as a recommendation for the program. It was a truly pain! I always had to adjust the text size and the line pitch to make the slides pleasant (i.e. to make it visually clear (on the first look) by distance and size which subitems belong to which main item).
Another disadvantage was that Keynote runs under Mac OS X as I normally only use Linux. While creating the slides I wanted to have my usual working environment (an old version (version 1.2.8) of the Galeon web browser with a good working session support, GNU Emacs in a non stupidly behaving terminal program for reading the Linux kernel source, xxdiff to compare the changes of the different Kernel preemption and lock-breaking patches) and so I used Keynote running in an instance of Mac On Linux. The problem with this is that Keynote uses direct hardware access to the NVRAM of the graphic card for the presentation mode (if I remember correctly) and so I always had to boot Mac OS X instead of Linux (i.e. not just Mac On Linux) to view the slides not only in the edit mode but in the real presentation mode. Very time consuming and peeving.
In fact the disadvantages caused my work on Acclaim as I wanted a presentation program whose slides where easy to create (at least for myself).
