Hindi/Devanagari presentations using orgmode, R, latex and beamer

org-beamer would now create the presentation without the outline frame.

Conkeror is a Firefox-based browser that adds emacs-style keyboard functionality to the browser. It is great for those who like using the keyboard (and hate the mouse). Try it.

Here is an interesting article on Conkeror browser.

I wish they thought of a better name though. Conkeror sounds too similar to Konqueror.
