1232 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1233 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1234 <p>I've been working on Mesa in my spare time for over five years. With Precision
1235 Insight I now have the opportunity to devote my full attention to advancing Mesa
1236 and OpenGL on Linux.</p>
1237 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1238 my work will continue to be open sourced and available to any other programmers who
1239 may want to contribute to it, or use it for other projects or platforms</p>
1240 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1243 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1244 Note that this is a new archive, so you will need to re-checkout the archive. That
1245 means don't <i>cvs update</i> from a previous download.</p>

1276 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1277 US$10,000 to the Mesa project to support its continuing development.
1278 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1279 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1280
1281 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1282 improve performance on 3d hardware.  Thanks to Keith's work, many
1283 applications using Mesa 3.1 will see a dramatic performance increase
1284 over Mesa 3.0.  The donation will allow Keith to continue working on
1285 Mesa full time for some time to come.
1286

1288 information about id Software, Inc. see www.idsoftware.com.
