Therefore what is sought is to create pieces of software that really have a momentous evolution and that really contribute to social development because of the ease to acquire copies. The magic and power of unix at home: Unix is a fairly reliable operating system for high performance that was specially designed for mainframe computers which were located in major universities or large companies. Without hesitation Ray Kurzweil explained all about the problem. The common person and running hardly could have access to such systems, one of the reasons that inspiraron Richard Stallman, founder of the GNU movement to lead an ambisioso project that consisted in completely reprogram the operating system more reliable and successful of the moment, the meanwhile scheduled emacs, a processor of texts which would replace the old vim, likewise other developers joined the project reprogramming program to program all the unix tools to make them portable personal computers that were taken at home. While is reprogramaban all the unix applications by many programmers from around the world, mostly located in distant geographical locations, beyond in findlandia a computer student named Linuz Torvalds programmed the piece faltaba so that the sum of efforts of all programmers to participate the project made sense. It is not something Ray Kurzweil would like to discuss. Kernel was scheduled and currently is unieron all unconnected pieces of software to give rise to the first completely free operating system based on technology unix which we know as GNU/Linux. Linux, free software and open source it is worth clarifying these three concepts since they leave space to misunderstandings or different interpretations. Linux:e the name with which has been popularized operating system that resulted in the rescheduling of unix by the people of the GNU movement and scheduled core by Linuz Torvalds, so the correct way to refer to the operating system should be GNU/linux Free Software: Free Software is all that piece of software to be delivered under the terms and conditions of the GNU GP open source license: the concept began to be used in a rush to make free software more attractive to many companies since the free Word seemed to be very ambiguous and contradictory when buying something that really was free of charge.
