GLIMS working group on Algorithms

[Bruce Raup]

Hello all.

I'd heard you were in Flagstaff, Andy.  Welcome to the western US.

I'm glad you're starting discussion on the glims_algor list.  The
subscribership seems stable now, so it's time to dive into discussions and
code sharing.

I like the definitions of the two subgroups.  However, of the two, I'd
guess that the "edge locations" groups has much more work ahead of it.

Is there a difference between "working group members" and "mailing list
subscribers"?  The list of subscribers to glims_algor is currently this
(obtainable by sending a message to majordomo at flagmail.wr.usgs.gov with
"who glims_algor" in the body of the message):

Perhaps we could identify specific software projects and have the initial
contributor of that software be the leader.

My personal wish is to have everyone feel they can participate in the
discussion whenever they want.  I think it should feel informal.

I suggest we be very project-centered.

If we have software projects that involve distributed development, we
need to have the code under revision control (e.g. RCS, or even CVS).  I
suppose this could be up to the keeper of the specific project, but I
think source control would make life much easier.

Cheers,
Bruce
