SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.
Unifdef is useful for removing #ifdef'ed lines from a file while otherwise leaving the file alone. You specify which symbols are defined or undefined with -D and -U flags, and unifdef removes the corresponding ifdefs, and the enclosed code if appropriate. It's especially useful for removing those "#ifdef BROKEN" and "#ifdef PRIVATE" clauses from code before you release it. Unifdef acts on #if, #ifdef, #ifndef, #elif, #else, and #endif lines, and it knows only enough about C and C++ to know when one of these is inactive because it is inside a comment or a single or double quote.
This is a patch for the popular Cistron RADIUS server to put the "users" file, including passwords in an LDAP directory. Integrating the radius server with LDAP has many benefits: all user accounts can be put in a central store, the store is easily replicated, and writing account management scripts also become easier with the multitudes of freely available LDAP browsers and administration tools.
Neohunt is an enhanced variant of hunt, a multiplayer game in which you run around a maze and shoot your friends before they shoot you. It is also an artifact of an earlier age, to be used either as nostalgia (if you remember the eighties) or as an example of how much better things are today (if you don't).
