mod_jail is an Apache module that supports 1.3.x and 2.x branches. It is similar to mod_chroot, but uses FreeBSD's specific system call "jail", which is more secure than chroot. Thus, it is intended to run on FreeBSD only. This module allows you to run Apache in a secure jail easily, without creating a real jail environment containing a copy of /lib, /libexec, /usr/lib, etc. Also, it is able to change the securelevel within a created jail prison.
V_Sim visualizes atomic structures such as crystals, grain boundaries, molecules, and so on It can work with files either in binary format or in plain text format. The rendering is done in pseudo-3D with colored spheres to represent the atoms. The user can interact through many functions to choose the view, the size of the atoms, their color, the background color, the type of fog, and more. Moreover, V_Sim allows you to export the view as images in GIF, PS, and other formats.

NTW Lisp is a server written in Common Lisp for applications that use the NTW protocol to communicate with a GUI client. This asynchronous protocol makes it possible to serve remote applications that are indistinguishable from native ones. It's also useful for quickly writing GUI apps from Common Lisp that can be run locally.
