OpenAL:
 So I'm maintaining my own MacOSX OpenAL implementation now.
   http://icculus.org/al_osx/

 I never realized we had so much mono8 data in ut2003...right now this is
 going through a scalar codepath, but some Altivec can clear that right up.
 On this 12" Powerbook, we're eating 2.5% of the CPU...this can become much
 faster.

 In real-world scenarios, __alcMixContext tends to beat up on the CPU cache
 more than I'd like, too...iterating over an array of sources to find the
 ones we are interested in is too expensive...this should really iterate over
 an array of pointers (and maybe just an array of pointers to playing
 sources)...the upper level mixing function, which just does some basic
 state management before branching out to the lowlevel mixers, shouldn't even
 show up in a Shark profile...on this system in ut2003, it's taking 0.1
 percent of the CPU.

 Other than that, the last notable optimization is to add AL_EXT_vorbis
 support to Unreal...this basically doubles the performance of the music
 rendering...probably save us 1 or 2% of the CPU (maybe less...but it's much
 more cache friendly and avoids a ton of float-to-int (and int-to-float)
 conversion, not to mention the Altivec fastpaths this adds.

 It's hard to quantify the precise amount of CPU time AL is taking...obviously
 some things show up in Shark, but (for example) calls to memcpy() will be
 attributed to libSystem without manual research...it'd be nice if there was
 a way for Shark to examine the callstacks and let you see all the CPU time
 a library is "responsible" for, even if the CPU time is being spent in an
 external library it called. Oh well.

 Jon C wrote in to say it IS in fact working on a G3 system, and others seem
 to be triggering an optimization bug in older gcc's. Please build with gcc
 3.3 (or try this build).


Duke3D:
 Stuff on the MacOS TODO list:
   1) x86 compatibility for savegames
   2) keeping Mac/PC networking in sync
   3) Coming up with a server browser/matching service.
   4) Add Cmd-Q as a quit key.
   5) Race condition in audiolib causes occasional crash.
   6) Ship it.


UTPG:
 Please stop emailing me to ask if this is done yet.

 Our source repository was experiencing technical difficulties for, well, 
 quite awhile. We're back online now, so we're gonna get all our changes 
 merged and move forward now. Hopefully there will be a new release soon.


Devastation:
 Please stop emailing me to ask if this is done yet.

 Server is out. Details here.
 Beta 1 of the Linux client is avaiable. Get it.


Unreal Tournament 2003:
 Going to get a patch out sooner than later. Nothing specific to report at
 this time.


Postal 2:
 Please stop emailing me to ask if this is done yet.

 The karma source is in my hands now, but the legal paperwork is still 
 being done.  :(


MOHAA:
 Yes, I know the binary expired. A new binary will be along 
 shortly. Sorry about that.

 Talked with EA today about Breakthrough, hoping source will be coming my 
 way shortly, once all the NDA stuff is cleaned up.


America's Army:
 Linux 1.9 is live: http://icculus.org/news/news.php?id=1616
 ...and the Mac version: http://icculus.org/news/news.php?id=1622

 If you're running on Linux and having trouble with Punkbuster because it 
 wants to write to a directory you don't have permission to, please read 
 this:

 You do NOT have to run the program as root. We'll automate this for the 
 next release, but this'll get you running in the short term.


Other stuff:

 I took a good portion of the day to clean up some open source projects 
 that have been simmering on the back burner for awhile. SDL_sound is now 
 at version 1.0.1 (a final stable release before new development can 
 begin), and I released my OpenAL on the world.
