[choroba]: Slidy is basically HTML, so I'm not sure I really fly high :)
choroba should make his presentation scaffolding public
[Corion]: choroba: spod5 converts pod to S5 HTML, so it's also still basic. I find the lack of animations (in the sense of "highlight this", "highlight that" in code) somewhat tedious as I do it with rendered PNGs
[Corion]: I haven't found a good way to include/use the source SVGs I use for creating the PNGs directly as animations
[ambrus]: Presentations come in many different shapes, and so slides do as well.
[Corion]: Doing that in Powerpoint or Ooxml would be nice(r) but I'm much quicker doing the outline of a presentation and the code as Pod
[Corion]: Hurrr - on a machine that is behaving weirdly, I have two processes CROND running. I guess that is the source of unattended jobs sometimes not finding their files anymore...
[ambrus]: Most of the time if I make slides, they're just a formatted document with a medium level of formality (between a well written article and an informal draft), with usually the page breaks chosen carefully and possibly some content repeated between pages.
