Finally... You will have to wait until MPI 3.0, in the hope we have support for portably communicating C99 bool data So in short, I think PetscTruth should remain being an enumeration.

The steps are simple: 1) Invite partychat2 at gmail.com to chat using the contacts on the left 2) Open a chat with partychat2 3) In the window type '/join petsc' 4) Then we can all talk at once, and it will be saved I think Matt On Mon, Jul 20, 2009 at 4:02 PM, Andy Ray Terrel wrote: > I guess by using GChat you really mean use PartyChat ( > http://techwalla.googlepages.com/home )?

I guess by using GChat you really mean use PartyChat ( http://techwalla.googlepages.com/home )? No google doesn't support IMAP or POP with GChat. There are some codes out there that do turn any jabber server into emails but they don't seem very polished ( http://people.happycoders.org/dax/projects/jmc ). I guess since most people are into gchat I shouldn't go on about irc. If you are going to use chat rooms I would also recommend getting to know dpaste ( http://dpaste.com ) which I find invaluable when debugging someone's code over a chat room. -- Andy

This is what irc is for and why lots of open source codes are on freenode servers. http://freenode.net/ Then you can pick what ever chat front end you want, log things for others to see, and so on. -- Andy On Mon, Jul 20, 2009 at 2:34 PM, Matthew Knepley wrote: > I have found chat to be the best way to resolve simple problems when coding, > especially > questions about parts I did not write.

I have found chat to be the best way to resolve simple problems when coding, especially questions about parts I did not write. It would be nice if we all had access to the same chat program to facilitate this kind of interaction in our small group. I tend to prefer GChat. Does anyone else have a preference? or really hate chat?
