376Structuring a talk is a difficult task and the following structure may not
377 be suitable.
378 Here are some rules that apply for this solution:
379\end_layout
380
381\begin_layout Itemize
382Exactly two or three sections (other than the summary).
383
384\end_layout
385
386\begin_layout Itemize
387At *most* three subsections per section.
388
389\end_layout
390
391\begin_layout Itemize
392Talk about 30s to 2min per frame.
393 So there should be between about 15 and 30 frames, all told.
394\end_layout
395
396\begin_layout Itemize
397A conference audience is likely to know very little of what you are going
398 to talk about.
399 So *simplify*!
400\end_layout
401
402\begin_layout Itemize
403In a 20min talk, getting the main ideas across is hard enough.
404 Leave out details, even if it means being less precise than you think necessary.
405
406\end_layout
407
408\begin_layout Itemize
409If you omit details that are vital to the proof/implementation, just say
410 so once.
411 Everybody will be happy with that.
