Hey guys,
So I got a huge response to the survey I sent out this morning. It
has led me to these two conclusions:
A lot of people use EPD. This means that the VTK stuff might closer
to general use than expected; additionally, it means that it might be
time to start moving to a TraitsUI based GUI. This would be easier,
much MUCH more flexible, and way simpler to maintain.
Nobody uses covering grids to do anything other than get objects that
align with the grid boundaries. This gives me license to rewrite them
to use int math for selection of cells. This should speed things up
(not just because of the int math, but because of the assumptions
about alignment I refused to make), make things easier, and allow the
kind of spatial organization that is necessary for properly converting
to vertex centered data.

Hi guys,
For some reason r1161 is having trouble parallel projecting for me on Ranger. I checked out r1160 and the same script ran to completion. r1161 runs for about two minutes, and gives nothing.
stderr gives:
setenv MY_NSLOTS 32

Guys,
Dave and I talked last night about standard deviation of profiles.
Can anybody see how to convert this one-pass algorithm:
http://www.cs.berkeley.edu/~mhoemmen/cs194/Tutorials/variance.pdf
into a weighted-average method? My brain is not working today.

Hi all,
Do any of you use covering grids (directly) to generate covering grids
that are misaligned with the cell boundaries?
I am considering writing a new routine to replace the existing one
that will work only with integer math; this should not only speed
things up, but simplify them substantially. Likely it would also
simplify the smoothing routines. I would send an email to yt-users
first, however.

Hi everyone,
I am projecting a thin volume of a dataset, and I'd like to limit HopCircleCallback to only plot the circles for haloes inside that region. Can anyone suggest an elegant way to do this? Thanks!
