supports: Free and open-source software (FOSS) is computer software that can be classified as both free software and open-source software. That is, anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright and the source code is usually hidden from the users. Marc Ewing ( born May 9 , 1969 ) is the creator and originator of the Red Hat brand of software , most notably the Red Hat range of Linux operating system distributions . He was involved in the 86open project in the mid- 90s . Ewing graduated from Carnegie Mellon University in 1992 . While at CMU , he was known to wear a red hat as he walked between classes . Because of his computer expertise , people would ask for help from the `` man in the red hat '' . Ewing and co-founder Bob Young named their initial software after the hat , and the name Red Hat stuck . At the height of the dot com bubble in 1999 , Ewing was briefly worth over 900 million dollars . Linus Benedict Torvalds (born December 28, 1969) is a Finnish software engineer who is the creator and, for a long time, principal developer, of the Linux kernel; which became the kernel for operating systems such as the Linux operating system, Android and Chrome OS. He also created the distributed revision control system Git and the diving logging and planning software Subsurface. He was honored, along with Shinya Yamanaka, with the 2012 Millennium Technology Prize by the Technology Academy Finland "in recognition of his creation of a new open source operating system for computers leading to the widely used Linux kernel". He is also the recipient of the 2014 IEEE Computer Society Computer Pioneer Award. sed ("stream editor") is a Unix utility that parses and transforms text, using a simple, compact programming language. sed was developed from 1973 to 1974 by Lee E. McMahon of Bell Labs,
  and is available today for most operating systems. sed was based on the scripting features of the interactive editor ed ("editor", 1971) and the earlier qed ("quick editor", 196566). sed was one of the earliest tools to support regular expressions, and remains in use for text processing, most notably with the substitution command. Other options for doing "stream editing" include AWK and Perl. Linux (pronounced or, less frequently) is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy. Open-source software (OSS) is computer software with its source code made available with a license in which the copyright holder provides the rights to study, change, and distribute the software to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. According to scientists who studied it, open-source software is a prominent example of open collaboration. An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. All computer programs, excluding firmware, require an operating system to function. The Linux kernel is a monolithic Unix-like computer operating system kernel. The Linux operating system is based on this kernel and deployed on both traditional computer systems such as personal computers and servers, usually in the form of Linux distributions, and on various embedded devices such as routers, wireless access points, PBXes, set-top boxes, FTA receivers, smart TVs, PVRs and NAS appliances. The Android operating system for tablet computers, smartphones and smartwatches is also based atop the Linux kernel. While the adoption on desktop computers is low, Linux-based operating systems dominate nearly every other segment of computing, from mobile devices to mainframes. , all but two of the world's 500 most powerful supercomputers run Linux. The other two run AIX on IBM power 7 hardware. Computer software, or simply software, is that part of a computer system that consists of encoded information or computer instructions, in contrast to the physical hardware from which the system is built. Unix (trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Red Hat, Inc. is an American multinational software company providing open-source software products to the enterprise community. Founded in 1993, Red Hat has its corporate headquarters in Raleigh, North Carolina, with satellite offices worldwide. The Free Software Foundation (FSF) is a 501(c)(3) non-profit organization founded by Richard Stallman on 4 October 1985 to support the free software movement, which promotes the universal freedom to study, distribute, create, and modify computer software, with the organization's preference for software being distributed under copyleft ("share alike") terms, such as with its own GNU General Public License. The FSF was incorporated in Massachusetts, USA, where it is also based. GNU is an operating system
  and an extensive collection of computer software. GNU is composed wholly of free software, most of which is licensed under the GNU Project's own GPL.
