Yaacfi is an authentication, authorization, and access control filter for J2EE Web applications. This filter loosely emulates J2EE servlet container role based security with some extensions, and allows to easily implement login procedures for much more complicated user interaction schemes than the standard container-based security form login procedure. These schemas are required to provide cookie login, openid login, explicit login, etc. The filter is completely compatible with Struts.
TCB::SysLoads is a DBIx::Frame object written to keep track of system loads, both local and remote, at the Theoretical and Computational Biophysics Group at UIUC. It provides an administrative web interface for adding and reading this information, plus a series of scripts for loading this information and a series of CGIs for extracting the information into graphs.
image_album generates HTML on-the-fly for the navigation of albums of related images.
