Brocard's problem is a problem in mathematics that asks to find integer values of n and m for which n ! + 1 = m 2 , {\displaystyle n!+1=m^{2},} where n! is the factorial. It was posed by Henri Brocard in a pair of articles in 1876 and 1885, and independently in 1913 by Srinivasa Ramanujan. == Brown numbers == Pairs of the numbers (n, m) that solve Brocard's problem are called Brown numbers. There are only three known pairs of Brown numbers: (4,5), (5,11...

curses is a terminal control library for Unix-like systems, enabling the construction of text user interface (TUI) applications. The name is a pun on the term “cursor optimization”. It is a library of functions that manage an application's display on character-cell terminals (e.g., VT100). == Overview == Using curses, programmers are able to write text-based applications without writing directly for any specific terminal type. The curses library on the executing system sends the correct control characters based on the terminal type. It provides an abstraction of one or more windows that maps onto...

Crouton (Chromium OS Universal Chroot Environment) is a set of scripts which allows Ubuntu, Debian and Kali Linux systems to run parallel to a Chrome OS system. Crouton works by using a chroot instead of dual-booting to allow a user to run two desktop environments at the same time: Chrome OS and another environment of the user's choice. == References == == External links == Crouton on GitHub Crouton on reddit Crouton Central on Google forums Crouton Users on Google+ Communities...
