If you want to do software and data analysis then you should read the
new online book from Tudor Girba:
about the Moose technology. Moose is an analysis platform written in Smalltalk.
The (yet unfinished) book already includes descriptions on how to use Moose, how to build a browser with Glamour or how to load the latest Moose version into Pharo using Metacello.
One interesting aspect (beside a good documentation on Moose) is that this is now the second dynamic web book on Smalltalk technologies (after the Seaside online book) which is written using the Smalltalk based Pier Content Management System.
