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.

Emacs.
Emacs is an app platform in and of itself, and the vanilla installation comes with dozens of its own apps pre-installed. Like how web apps are all programmed in JavaScript, Emacs apps are all programmed in Lisp. All Emacs apps are scriptable and composable in Lisp. Unlike on the web, Emacs encourages you to script your apps to automate things yourself.
Emacs apps are all text based, so they all work equally well in both the GUI and the terminal.
Emacs comes with the following apps pre-installed:
Some apps that I install into Emacs include:
It comes also with a doctor, you can invoke it with "M-x doctor". I discovered Emacs in the 80s, used it a lot in uni in the 90s, Emacs is a religion, or an OS, it's so powerful it's incredible. Nowadays I'm mostly using code for coding, or simply nano for small scripts/text.
Philosophy is a subset of religion, and there is a definitely an Emacs philosophy about making absolutely all software hackable, and controlling the computer using text.
App platforms are a subset of operating systems. People confuse the two because most app platforms are inseparable from the operating system on which they run. But some software, like the Web, or Java, or to some extent .NET/Mono, are app platforms that run the same apps across multiple operating systems. Emacs is an app platform.
