639 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
640 Inc. effective October,
1999. I'll be leaving Avid Technology in September.
</p>
641 <p>I've been working on Mesa in my spare time for over five years. With Precision
642 Insight I now have the opportunity to devote my full attention to advancing Mesa
643 and OpenGL on Linux.
</p>
644 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
645 my work will continue to be open sourced and available to any other programmers who
646 may want to contribute to it, or use it for other projects or platforms
</p>
647 <p>PS: I'm going to be traveling until Sep
6 and won't be reading email until then.

1999 - John Carmack of id Software, Inc. has made a donation of
684 US$
10,
000 to the Mesa project to support its continuing development.
685 Mesa is a free implementation of the OpenGL
3D graphics library and id's
686 newest game, Quake
3 Arena, will use Mesa as the
3D renderer on Linux.
688 The donation will go to Keith Whitwell, who has been optimizing Mesa to
689 improve performance on
3d hardware. Thanks to Keith's work, many
690 applications using Mesa
3.1 will see a dramatic performance increase
691 over Mesa
3.0. The donation will allow Keith to continue working on
692 Mesa full time for some time to come.
694 For more information about Mesa see www.mesa3d.org. For more
695 information about id Software, Inc. see www.idsoftware.com.
