X Window System

Filed under
Linux

The X Window System (www.x.org) was created in 1984 at the Massachusetts Institute of Technology (MIT) by researchers working on a distributed computing project and a campuswide distributed environment, called Project Athena. This system was not the first windowing software to run on a UNIX system, but it was the first to become widely available and accepted. In 1985, MIT released X (version 9) to the public, for use without a license. Three years later, a group of vendors formed the X Consortium to support the continued development of X, under the leadership of MIT. By 1998, the X Consortium had become part of the Open Group. In 2001, the Open Group released X version 11, release 6.6 (X11R6.6).

Linux Performance Hunting Tips - Take Copious Notes (Save Everything)

Probably the most important thing that you can do when investigating a performance problem is to record every output that you see, every command that you execute, and every piece of information that you research. A well-organized set of notes allows you to test a theory about the cause of a performance problem by simply looking at your notes rather than rerunning tests. This saves a huge amount of time. Write it down to create a permanent record.
