Oh, one more thing. Keep on hand some of your previous presentations. Often, a speaker won't show up and the conference organizer is panicking and needs a replacement. Be first to volunteer your services! I've done that several times, and the results were always worthwhile.
One time, I didn't have an extra talk with me, but I volunteered anyway and asked for a whiteboard and markers. Frankly, it was the best talk I ever gave. Unfortunately, it wasn't recorded. But it sure was fun! (I simply asked the audience what they wanted me to talk about.)
I once got a panicked email from a conference organizer in Japan at about 3AM because a speaker was at another event and completely forgotten about this one. (Hey! Happens.) I was able to be like, no problem. Here's a presentation that works.
And, if need be, I could have just done something on the fly instead.
