Dear all,

Planning ahead. It would be nice to compile Anaconda for science
sometime in the future.

Regards,

Robert

This is immensely valuable to a scientific programmer.  Without that one must use temporary variables when debugging.  While the optimization process will remove the overhead, it makes the code quite long winded and ugly.

In particular, how good is VBox for that?  it's become very Windows host oriented.  I'm also aware the Solaris USB support is not very good.  I'll have Win 7 and Debian available  running native on a Z400 if USB proves an issue for working with microcontrollers which is my primary use case for both of those.
