I gave a plenary talk at a big MAA meeting a few months ago. It was entirely a live demo using the Sage notebook. It went perfectly. Stan Wagon gave another talk in using the Mathematica notebook, and it surprisingly had numerous bugs/problems as a result of bugs in Mathematica's notebook. The reason my talk went well was that: (1) I carefully prepared it. (2) I carefully tested it, especially deleting all input cells then clicking "Action --> Evaluate All" before the talk a few times, just to make sure the talk really worked. Using Evaluate All before the talk is absolutely critical. It's also a very good idea to always have a backup plan, i.e. some sort of static version of the talk (like what Marshall describes above, or just pdf of something) just in case. E.g, have a working version of the talk installed and tested on a remote server "just in case". Another easier static version that feels must more like the notebook while being "safe" is to take screenshots of each slide in the worksheet. A big problem remaining with giving a talk is the sometimes potential random reordering of some cells when using TinyMCE, which is a real bug though nobody knows how to systematically trigger it. This only happens when editing a lot, so as long as your talk is good right before you give it, then you're fine. Honestly, it is very hard to "sell" Sage as a tool for presenting mathematics to undergraduates when one is afraid to actually use it to give a talk. It's especially hard when the other speakers are giving talks using Maple and Mathematica. Having a good presentation mode for Sage really is important. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
