Sophie is a daemon which uses 'libsavi' library from Sophos anti-virus vendor (http://www.sophos.com). On startup, Sophie initializes SAPI (Sophos Anti-Virus Interface), loads virus patterns into memory, opens local UNIX domain socket, and waits for someone to connect and instructs it which path to scan. Since the database is loaded in RAM, scanning is very fast. (Note: speed of scanning also depends on SAVI settings and size of the file.) It works on Linux, Solaris (Sparc/x86), HP-UX, and FreeBSD.
WIPORT is a layer over the grx graphics library which provides a simple GUI API with memorization of the objects displayed in the various windows. This makes redrawing and printing to a scalable PostScript representation easy to do. Thanks to the grx library programs, using WIPORT works identically on the DOS graphical console, Linux+svgalib, and Linux+X11. WIPORT is written in C and comes with an Ada-95 binding.
DIOTA is a just-in-time instrumentation tool for Intel binaries. It allows you to create a dynamic loadable library that can be attached to a program running under Linux. DIOTA can instrument all memory operations in the application and the used libraries (e.g., for checking for faulty memory accesses), calls of dynamically linked procedures (malloc, printf, etc.), detect the code executed during a particular run, and more.
