This question already has an answer here:
I've watched 50 plus presentations on programming topics, although most have been online; example, Google Tech Talks -- and have ad-hoc experience on what formats work for programmers, or practices to take into account when presenting to a group of programmers.
That said, I'm open to any suggestions, but here's some topic of the top of my head:
- Programming Jokes, Images, etc.
- Posting Code for download
- Contact Info
- Collecting feedback
- Presenting Code on Screen
If it matters, in this case -- I'm giving a presentation on using a scripting language to extract, transform and load data to a local user group who's focus is the scripting language; Ruby in this case.
Questions, feedback, requests -- just comment, thanks!!
