Disclaimer 1: The title of this article is purposefully exaggerated. This article has no intention to even imply that the work of a secretary is somehow inferior to the work of a scientist. It is not! I have done such work and I know that almost no secretary is as appreciated as she/he should be.

I just read that in the US, college graduates have trouble landing jobs related to their education if at all . This vividly reminds me of a TED talk given by Andrew McAfee about what future jobs will look like. The following is a video really worth watching!
I am sure you have heard that the image of an object created on your eye’s retina is inverted (rotated by 180 degrees).

She probably meant to write modern crowd-sourcing as some forms of crowd-sourcing have been in use since long time ago as we will see further below.

This post is a tutorial on creating web presentations with free software. The software used is CamStudio (http://camstudio.org/) and optionally a web camera software called Yawcam (http://www.yawcam.com/). Yawcam is a camera software which can “stay on top” while you are presenting your slides. It is capable of showing your face or whatever is in front of your web camera during your presentation. So the end result will look somewhat like picture in picture functionality. The tutorial is given in video format below as well as in written instructions format. Feel free to follow whatever suits you best. Continue reading How to create web presentations using free software available online→
