SysScope is a graphing solution that facilitates the visual representation of RRDtool's Round Robin Databases (RRD). It retrieves the graph options from an Apache-style configuration file and, after making the necessary calls to rrdgraph, it generates static or dynamic HTML pages containing the graphs. The following backends are supported for the generation of the dynamic pages: CGI, FastCGI, mod_python, and WSGI.
Whiskers is an educational PocketPC application that tries to exploit all the hardware available on most common PDAs providing a link between different features such as GPS-Bluetooth-Wireless. Generally, whiskers was built with radio reconnaissance in mind as help for geocachers or wardrivers, but also as a penetration and audit tool. There is support for in-depth device scanning, triggering actions based on filters when certain devices are in range, centralized GPS logging with search functions for private or public databases, and much more.
Diskus is a high-level hard drive diagnostic and limited repair tool. It checks the disk geometry by writing numbered IDs into the sectors of the hard drive. Later one can verify that these sector-IDs on the disk are still correct, thereby detecting data which was not correctly written. There is an option to "freshen" the data on your harddrive, which will read and rewrite the sectors. With modern drives this will re-map defective sectors.
jdiagnostics is a library of routines for inspecting the state of a JVM and building a support bundle. It makes it easy to diagnose issues with classpaths, resources, serviceloaders, versioning, XML parsers, and so forth. It has no dependencies, and is an essential library to build into any infrastructure application.
