MOSES no longer to submit patches to OpenSim

After what can be described as a contentious period between the MOSES project that use OpenSim for training of US Army staff and OpenSim core developers, the project has in a statement to the opensim-dev mailing list stated they no longer will contribute patches to OpenSim.  

The MOSES project is not suggesting, alluding, or hinting at anything.  I am stating for the record, based on our experiences with the code acceptance practices of the Open Simulator project, that the process is subjective.   

The MOSES project will longer submit patches.  This decision is based on the advice of one of the Open Simulator developers.  We will be working strictly from our public GitHub.  We will announce when code is ready for pulls.  You may do with it as you wish, and we will be available for consult should you want to modify it for inclusion in the Open Simulator codebase.  We are also writing a detailed "Open Sim PhysX API" document that you will find useful.  This decision allows for you to work at the pace you are accustomed to and it will not impact our schedule.

Although we are no longer submitting patches, if you work with us we can ensure the code that produced is in a state you would find immediately ingestible.

Good Luck.

MOSES have in the past submitted patches to refine statistics collection to more accurately reflect the real performance of the OpenSim server and is currently developing a new version of the PhysX physics engine that will be able to run on NVIDIA graphics cards, and in the future distributed on dedicated physics servers. PhysX is already used by the InWorldz grid, but running on regular CPUs. Its performance has by many been seen to be superior to the current bulletsim physics plugin that is now standard in OpenSim. 

In addition the MOSES project has made available OAR archives of parts of their regions and content developed for training. XMIR’s Murat River Valley area contains 6 modified versions of these regions.
