Colophon

Type

The typeface used on this site is Function Pro, which is a redrawing of the Futura typeface designed by Paul Renner in 1927.

Renner believed that modern typefaces should not be based on old designs. He took letter-forms down to the bare essentials, and built Futura with simple geometric shapes, such as the circle, the square, and the triangle. The result was a very modern-looking sans-serif, that, with the help of the Bauer Type Foundry of Frankfurt, Germany, became an enormous success.

Foundational Infrastructures

We also need to acknowledge (though I think it would be impossible to do so properly) the thousands of developers that have contributed to the many Unix-related infrastructures and middlewares on top of which we have built this project, specifically those from the Arch Linux, CentOS, and SmartOS communities. The breadth and scope of the effort required to create and maintain these infrastructures, as well as the good that has come into the world because of them, is unfathomable.
