349Structuring a talk is a difficult task and the following structure may not
350 be suitable.
351 Here are some rules that apply for this solution:
352\end_layout
353
354\begin_layout Itemize
355Exactly two or three sections (other than the summary).
356
357\end_layout
358
359\begin_layout Itemize
360At *most* three subsections per section.
361
362\end_layout
363
364\begin_layout Itemize
365Talk about 30s to 2min per frame.
366 So there should be between about 15 and 30 frames, all told.
367\end_layout
368
369\begin_layout Itemize
370A conference audience is likely to know very little of what you are going
371 to talk about.
372 So *simplify*!
373\end_layout
374
375\begin_layout Itemize
376In a 20min talk, getting the main ideas across is hard enough.
377 Leave out details, even if it means being less precise than you think necessary.
378
379\end_layout
380
381\begin_layout Itemize
382If you omit details that are vital to the proof/implementation, just say
383 so once.
384 Everybody will be happy with that.
