Scipy is open-source software for mathematics, science, and engineering. The core library is NumPy which provides convenient and fast N-dimensional array manipulation. The SciPy library is built to work with NumPy arrays, and provides many user-friendly and efficient numerical routines such as routines for numerical integration and optimization. Together, they run on all popular operating systems, are quick to install, and are free of charge. NumPy and SciPy are easy to use, but powerful enough to be depended upon by some of the world's leading scientists and engineers.
The screen utility allows you to have multiple logins on just one terminal. Screen is useful for users who telnet into a machine or are connected via a dumb terminal, but want to use more than just one login. Install the screen package if you need a screen manager that can support multiple logins on one terminal.
Scrub writes patterns on files or disk devices to make retrieving the data more difficult. It operates in one of three modes: 1) the special file corresponding to an entire disk is scrubbed and all data on it is destroyed; 2) a regular file is scrubbed and only the data in the file (and optionally its name in the directory entry) is destroyed; or 3) a regular file is created, expanded until the file system is full, then scrubbed as in 2).
