443Structuring a talk is a difficult task and the following structure may not
444 be suitable.
445 Here are some rules that apply for this solution:
446\end_layout
447
448\begin_layout Itemize
449Exactly two or three sections (other than the summary).
450
451\end_layout
452
453\begin_layout Itemize
454At *most* three subsections per section.
455
456\end_layout
457
458\begin_layout Itemize
459Talk about 30s to 2min per frame.
460 So there should be between about 15 and 30 frames, all told.
461\end_layout
462
463\begin_layout Itemize
464A conference audience is likely to know very little of what you are going
465 to talk about.
466 So *simplify*!
467\end_layout
468
469\begin_layout Itemize
470In a 20min talk, getting the main ideas across is hard enough.
471 Leave out details, even if it means being less precise than you think necessary.
472
473\end_layout
474
475\begin_layout Itemize
476If you omit details that are vital to the proof/implementation, just say
477 so once.
478 Everybody will be happy with that.
