CERNLIB is a suite of data analysis tools and libraries created for use in physics experiments, but also with applications to other fields such as the biological sciences.

MRTGutils is a collection of simple utilities to generate output useful for mrtg. Many of the existing mrtg setups use shell or perl scripts to gather output. On busy systems, these scripts can generate a lot of extra load. These (small) C programs can return the given statistics more efficiently.

SimpleID is a simple, personal OpenID provider written in PHP. OpenID is a way to provide for a single digital identity across the Internet. To get an OpenID you need to sign up to an OpenID provider, who acts as the "custodian" of your digital identity. Every time you want to log into an OpenID-enabled web site, you will be redirected to your OpenID provider, who will then verify your identity and provide this to the web site.

POD allows for the documentation of Perl code. But with a few tricks, e.g., when disguised as comments, it is applicable to many other languages, too. It resembles HTML in the way that it allows for the structured representation of text. Hence, it looks rather good when converted for printers, HTML or man pages.

Mauve is intended to test several different varieties of the libraries. For instance, it will contain tests that are specific to a particular JDK version. Tags in the test files help the test framework decide which tests should or should not be run against a given runtime.

For various valid reasons, open-source program sources rarely derive the mathematical formulas they use. A user, nevertheless -- not wishing to take such formulas on faith -- might wish to see such formulas *somewhere* derived.
