Programming Groovy, 2^nd Edition (pre-release)

Venkat Subramanian

Users of Groovy 2.0 have been aware for quite some time that the latest release of their language is desperately short of documentation. Revisions to the canonical book (Groovy in Action) have been in the works for years with effectively no progress. The particularly frustrating aspect of these delays is that the 2.0 release delivers numerous improvements to the language. Finally, though, this book is breaking the long wait. Subramanian's first book on Groovy was a short, direct affair (as are most of his works) that targeted Java programmers and presented "what you need to know," quickly and directly. The current beta of this book (release is expected in the first half of 2013) gives you the running start you need to dive into Groovy 2.0 today. (Note: If you buy this pre-release beta version now, you will be entitled to the final version when it comes out.)

Intermediate Perl, 2^nd Edition

Randal Schwartz, et al.

Schwartz is a well-known figure in the Perl community since its early days. This book takes the material he provides in an intermediate course on the language and converts it into a readable presentation on more advanced aspects of the language. As it assumes that the reader already has knowledge of Perl, (Schwartz's Learning Perl is a common introductory text), it skips over the basics and tackles topics such as OO in Perl (using the Moose object system), testing Perl code, and so on. If you've got your basic training done in the language, this is likely to be the book that will take you to the deeper knowledge you'll need for professional-level work.
