XStandards - X Window System Standards and Specifications
The major goal of the X Consortium was to promote cooperation within the computer industry in the creation of standard software interfaces at all layers in the X Window System environment. The X Consortium produced standards - documents which defined network protocols, programming interfaces, and other aspects of the X environment. These standards continue to exist in the X.Org Foundation releases. The X.Org Foundation also produces specifications. Like X Window System Standards, these are documents which define network protocols, programming interfaces, and other aspects of the X environment. Under the aegis of The Open Group, X Window System standards, X.Org Foundation specifications, and other specifications are the basis for portions of The Open Group's various CAE specifications. The status of various standards, specifications, and the software in the X11R7.0 distribution, is explained below.

The X11R7.0 distribution contains sample implementations, not reference implementations. Although much of the code is believed to be correct, the code should be assumed to be in error wherever it conflicts with the specification. The only X Window System standards are the ones listed above. No other documents, include files, or software in X11R7.0 carry special status within the X Window System. For example, none of the following are standards: internal interfaces of the sample server; the MIT-SHM extension; the Athena Widget Set; the Xmu library; the Xau library; the RGB database; the X Locale database; the fonts distributed with X11R7.0; the applications distributed with X11R7.0; the include files <X11/XWDFile.h>, <X11/Xfuncproto.h>, <X11/Xfuncs.h>, <X11/Xosdefs.h>, <X11/Xos.h>, <X11/Xos_r.h>, <X11/Xwinsock.h>, and <X11/Xthreads.h>; the bitmap files in <X11/bitmaps>. The Multi-Buffering extension was a draft standard of the X Consortium but has been superseded by DBE as a standard.
The X.Org Foundation maintains a registry of certain X-related items, to aid in avoiding conflicts and to aid in sharing of such items. The registry is published as part of the X Window System software release. The latest version may also be found at ftp://ftp.x.org/pub/DOCS/registry The X Registry and the names in it are not X Window System standards.
Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.
Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.
Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.
The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.
Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.
Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
