Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can email us for advice or just use some of the how-to screencasts on the site. This screencasting learning-path is a good place to start.

nice. funny presentation. but i miss something like a self-updating directory, like TeX provides, where you write your document and then a directory is created out of your document (and if the question arises why I don't teX in the first place, I have to use OpenOffice.)
