Gross national product measures everything, except that which makes life worthwhile

In March 1968, Robert F. Kennedy spoke about a governing elite who had lost touch with ordinary people and judged the state of the nation by gross national product.

"Gross national product counts air pollution and cigarette advertising, and ambulances to clear our highways of carnage,” he said. “It counts special locks for our doors and the jails for the people who break them.”

“Yet the gross national product does not allow for the health of our children, the quality of their education or the joy of their play,” he continued. “It does not include the beauty of our poetry or the strength of our marriages, the intelligence of our public debate or the integrity of our public officials. It measures neither our wit nor our courage, neither our wisdom nor our learning, neither our compassion nor our devotion to our country. It measures everything, in short, except that which makes life worthwhile.”

Microsoft Open Sources .NET and Mono under MIT (tirania.org/blog/)

Today, Scott Guthrie announced that Microsoft is open sourcing .NET. This is a momentous occasion, and one that I have advocated for many years. .NET is being open sourced under the MIT license. Not only is the code being released under this very permissive license, but Microsoft is providing a patent promise to ensure that .NET will get the adoption it deserves. The code is being hosted at the .NET Foundation's github repository. This patent promise addresses the historical concerns that the open source, Unix and free software communities have raised over the years. Read more.
