1225 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1226 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1227 <p>I've been working on Mesa in my spare time for over five years. With Precision
1228 Insight I now have the opportunity to devote my full attention to advancing Mesa
1229 and OpenGL on Linux.</p>
1230 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1231 my work will continue to be open sourced and available to any other programmers who
1232 may want to contribute to it, or use it for other projects or platforms</p>
1233 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1236 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1237 Note that this is a new archive, so you will need to re-checkout the archive. That
1238 means don't <i>cvs update</i> from a previous download.</p>

1269 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1270 US$10,000 to the Mesa project to support its continuing development.
1271 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1272 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1273
1274 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1275 improve performance on 3d hardware.  Thanks to Keith's work, many
1276 applications using Mesa 3.1 will see a dramatic performance increase
1277 over Mesa 3.0.  The donation will allow Keith to continue working on
1278 Mesa full time for some time to come.
1279

1281 information about id Software, Inc. see www.idsoftware.com.
