List of Helpful Individuals

RANDOM.ORG is a true random number service that generates randomness via atmospheric noise. This page is a thanks to a lot of people without whom the service would not have been possible.

Trinity College, Dublin

A lot of people in Trinity College, Dublin deserve thanks for their help with RANDOM.ORG. In particular, I am grateful to the Distributed Systems Group (DSG) and the School of Computer Science and Statistics (SCSS) for letting me host the server here.

A number of former students have helped with RANDOM.ORG and deserve a very special thanks. One of the great things about being in a university is that you get to work with such motivated and intelligent students.

Charmaine Kenny (2005) conducted the most detailed analysis of the RANDOM.ORG numbers so far.
Louise Foley (2001) conducted the first analysis of the RANDOM.ORG numbers.
Antonio Arauzo Azofra (2001) built a super-fancy statistics module based on Louise Foley's analysis.

You can download Charmaine's and Louise's reports from the Analysis Page.

I am also very grateful to the following colleagues:

Dr Kris Mosurski for supervising Charmaine Kenny's project in 2005 and for many interesting conversations since then.
Dr Simon Wilson for supervising Louise Foley's project in 2001.
Dr René Meier and Dr Jim Dowling from the Digital Business Ecosystem (DBE) who donated a Dell Dimension 4550, which served as RANDOM.ORG server for most of 2007.

Web Programming and Design

I am very grateful to a few highly competent and very generous guys who have donated code used on the web server.

Tim Shank has donated the new web design, which is not only very readable and pretty stylish, but also conforms to the XHTML and CSS standards.
Bo Allen wrote a nice piece of CSS code that solved a particularly tricky problem with the search box.
Andronikos Nedos wrote the SOAP server; this is currently in the process of being updated.

The Open Source Community

RANDOM.ORG would not have been possible without the great software that so many people from the open source community have built. The following deserve a special mention for their great software.

Everyone behind the amazing GNU/Linux software base
The Debian team for putting together a great distribution
The Apache HTTP Server team for a fantastic web server
The people behind the GMP arbitrary precision arithmetic library
