590 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
591 Inc. effective October,
1999. I'll be leaving Avid Technology in September.
</p>
592 <p>I've been working on Mesa in my spare time for over five years. With Precision
593 Insight I now have the opportunity to devote my full attention to advancing Mesa
594 and OpenGL on Linux.
</p>
595 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
596 my work will continue to be open sourced and available to any other programmers who
597 may want to contribute to it, or use it for other projects or platforms

6 and won't be reading email until then.

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