I'm curious as to how you decided to use ORBit. At my work place, we ar
Ok, probably nobody cares, but the group I work for/with has pretty
much finished our first iteration of the Redstar3 array controller.
An array in this case is an infrared ccd. The system is the main
controller for imaging for astronomy. I mention it only because it's
running Linux.

Ok, I lied. For some reason I thought most of the memory was free when
we first power up the system, but it comes up with about 200MB used.
Seems like a lot, but I don't see anything hogging it all, so maybe it's
just allocating memory really freely to the processes that are there.
When first
Well, maybe. The primary reason I bring the Redstar3 up here is because
there have been several times over the last year when I've gotten good
feedback when stuck on some aspect of the system design or
implementation, and I feel the Luau made a definite and positive
contribution.
I thank you

I have a "dedicated system" (what do you call a system that's obviously
not embedded but is designed (destined?) for a very narrow scope of

The system's got 512 MB main memory. When we fi
