[Opensim-users] toward a new client

Wed Dec 3 23:00:50 UTC 2008

Simple compatibility is not in question - I'm well aware that opensim runs
on both windows and linux.

That being said, having a language specification, however clear it may be,
is not exactly the same thing as having a working language.

THAT being said, the 'crash here' and the 'memory leak there' are sufficient
to keep Nebadon busy restarting the OSGrid linux plazas, and the memory
leaks are sufficient to prevent us running more than a single region
effectively on a linux box with 1GB (typically, we can conservatively get
about twice the bang for the buck running the server on a windows platform).

My concern is that as the "independent developement companies'' produce
progressively more code that runs only on windows (I'm mainly focussing on
the viewer here, as that is what we were actively discussing, at least
initially), we will get into a situation not unlike the one linux is in: it
is percieved as being a great server platform and a sorry desktop
environment.

I am TRULY desirous of using the rex code - I'd test the simulator eagerly
if I thought there was a prayer of my being able to see the benefits on a
linux desktop.

Until that happens, this is just one more step towards their viewer and
server extensions becoming 'windows only'.

IMHO, that would be a tragedy. Us greybeards would like to use it too.

Cheers
James
