You might not have seen it yet, but a new SilverStripe book has been
published:
http://www.amazon.com/Silverstripe-Module-Extension-Themes-Widgets/dp/184951500X
Official website:
http://www.packtpub.com/silverstripe-2-4-module-extension-themes-and-widgets/book
Code:
https://github.com/xeraa/silverstripe-book
Why am I writing this to the mailing list as people here already know
(almost) everything about SilverStripe? We're still looking for
reviewers. Get in touch with me via pk at xeraa dot net and I'll get
you a review copy!
And of course pointers to the book for people wanting to get started
with SilverStripe or like having a printed reference are highly
appreciated.
Don't be discouraged by the "Beginner's Guide". While the book starts
with a gentle introduction a lot of content is covered - just take a
look at the table of contents on Amazon.
PS: SilverStripe Inc is not associated with the book, it was solely
written by me (Philipp Krenn). However I had three fantastic
reviewers: Sigurd Magnusson, Ingo Schommer, and Aaron Carlino.
