The abstracts and presentations for VISualize 2012 are now available from the Exelis VIS website.
Also, James Goodman from HySpeed Computing wrote an article on his experience at VISualize:
A central topic of discussion in the presentation by HySpeed Computing, and a common theme heard around the conference, is the need for increased collaboration, improved access to analysis tools, and greater data accessibility.
I agree. Even though James was talking about the ENVI community and used the IDL community as an example with good code sharing, I think we could do a lot better.
