Cryptographers devote their careers to the science of securing your communications. Twenty-four-year-old Nadim Kobeissi has devoted his to the art of making that security as easy as possible. His software creations like Cryptocat and Minilock are meant to encrypt instant messages or shared files with three-letter-agency-level protection, but with user interfaces that require Lincoln-Log-level skills. Now he's pulling elements of all his dead-simple apps into what he describes as his biggest release yet, a single platform designed to encrypt everything you and any group of collaborators do on the desktop.

This document is designed as an introduction to thinking ethically. We all have an image of our better selves-of how we are when we act ethically or are "at our best." We probably also have an image of what an ethical community, an ethical business, an ethical government, or an ethical society should be. Ethics really has to do with all these levels-acting ethically as individuals, creating ethical organizations and governments, and making our society as a whole ethical in the way it treats everyone.

This is excellent. I like these lines "Only by careful exploration of the problem, aided by the insights and different perspectives of others, can we make good ethical choices in such situations." and also the steps. I have linked it on my wiki. Thanks Sandra.

An older article (2007) but still a worthy look at one of the biggest and most famous projects of this type. Includes a video where David Pogue demonstrations throwing water over the machine and dropping it from 4ft (students always like that bit :D)
