The standard way of including source code listings in Beamer is to use the semiverbatim environment. Needless to say, it does not provide all the syntax highlighting and line-numbering love of the listings package. Combine the two and you have something pretty as well as extremely helpful in delivering presentations which have code:

Continuing the process of presenting my proposal for the graduation project, I was required to do a presentation. Now, I have never really liked PowerPoint and for more reasons than it being a product of Microsoft (I was never really into OpenOffice.org Impress either).

In fact, I have never liked doing presentations in the first place. My preferred means of communicating an idea is through written material or face-to-face discussions. Anyhow, seeing as I had to do a formal presentation, I turned towards the solution that would provide some additional attraction for me: Beamer.

After fiddling around with my .tex for a few hours, I was able to create something which looked ^[*] far more professional, sexier and informative than anything I had ever created using traditional presentation software:

ittc-defense-presentation.pdf

To view the presentation you have to open it in “Slide Show” mode of your favorite PDF reader. What totally blew me away was the ease with which I could create lovely bibliographic references, mathematical equations and little fun things like navigational bar on top of every page. Perhaps it’s got to do something with the mindset of a programmer, but I certainly became more productive with Beamer within a couple of hours than I had been throughout my experience with PowerPoint/Impress.

^[*] Whether they were professional, sexy or informative is a totally different matter and has very little to do with either LaTeX or Beamer.
