From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Edwin
Edwin an Emacs-like editor programmed by some of the guys who maintain the MIT-Scheme programming language, which is (I think) the original implementation of the Scheme programming language developed by Gerald J. Sussman and Guy Steele (or a predecessor of it). To this day, MIT-Scheme continues to be one of the fastest Scheme implementations, producing extremely efficient binaries for a high-level language.
It is Emacs-like in nature, except instead of scripting it in Emacs Lisp, you use Scheme. Unlike Emacs, there are very few extensions available for it, so no Org-Mode, no Magit, no nice themes. The GUI version of it is so antiquated, it uses its own widget toolkit that is similar to the Athena Widget Toolkit.
Although I use Emacs for everything, I still love Edwin just because I like Scheme as a language better than Emacs Lisp. I wish I had more free time, I would like to help modernize Edwin. Although at this point it would probably easier to write a whole new Emacs-like editor using Guile Scheme instead, since there is a very active user community around Guile Scheme, especially among the Guix OS clique.
