How to display documents without being copied?
The Google programmers came up with a means for displaying excerpts from docs such as pdf, MS Office, etc without needing flash but still maintaining control for viewing / copying. Basically the program converts doc pages to .png files, and optionally protects the page display thru obfuscation so the client browser cannot access the image's url.

*: Five minutes of exercise in nature improves physical and mental health: A study in the journal Environmental Science & Technology found that just a five-minute 'dose' of exercising in nature provided the biggest boost in people's self esteem. The study further found that being active in natural spaces with water provided additional improvements in people's mental health.
On Open Source Technology
(Cooperation Makes Sense)
“The basic idea behind open source is very simple. When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.
“ We in the open source community have learned that this rapid evolutionary process produces better software than the traditional closed model, in which only a very few programmers can see the source and everybody else must blindly use an opaque block of bits.” —from OpenSource.org

What is Ubuntu?
I like using the open-source linux distribution called "Ubuntu" as the operating system on most of my PCs. Why? It's free! And more efficient, and more socially cooperative in spirit. (I also have Windows PCs, a Mac notebook, an iPad and a Kindle Fire tablet.) Here's a definition of Ubuntu:"I am what I am because of who we all are." (From a translation offered by Liberian peace activist Leymah Gbowee.)
A person with Ubuntu is open and available to others, affirming of others, does not feel threatened that others are able and good, for he or she has a proper self-assurance that comes from knowing that he or she belongs in a greater whole and is diminished when others are humiliated or diminished, when others are tortured or oppressed.
Tutu further explained Ubuntu in 2008:
One of the sayings in our country is Ubuntu – the essence of being human. Ubuntu speaks particularly about the fact that you can't exist as a human being in isolation. It speaks about our interconnectedness. You can't be human all by yourself, and when you have this quality – Ubuntu – you are known for your generosity.
We think of ourselves far too frequently as just individuals, separated from one another, whereas you are connected and what you do affects the whole World. When you do well, it spreads out; it is for the whole of humanity.
