benrothke writes: Far too many technology books take a Hamburger Helper approach, where the first quarter or so of the book is about an introduction to the topic, and filler at the end with numerous appendices of publicly available information. These books end up being well over 800 pages without a lot of original information, even though they are written an advanced audience. In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn't a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. Using that approach for the cloud, in Cloud Computing Design Patterns, authors Thomas Erl, Robert Cope and Amin Naserpour have written a superb book that has no filler and fully stocked with excellent and invaluable content. Keep reading for the rest of Ben's review.

An anonymous reader wrote in with a story on OS News about the latest release of the Genode Microkernel OS Framework. Brought to you by the research labs at TU Dresden, Genode is based on the L4 microkernel and aims to provide a framework for writing multi-server operating systems (think the Hurd, but with even device drivers as userspace tasks). Until recently, the primary use of L4 seems to have been as a glorified Hypervisor for Linux, but now that's changing: the Genode example OS can build itself on itself: "Even though there is a large track record of individual programs and libraries ported to the environment, those programs used to be self-sustaining applications that require only little interaction with other programs. In contrast, the build system relies on many utilities working together using mechanisms such as files, pipes, output redirection, and execve. The Genode base system does not come with any of those mechanisms let alone the subtle semantics of the POSIX interface as expected by those utilities. Being true to microkernel principles, Genode's API has a far lower abstraction level and is much more rigid in scope." The detailed changelog has information on the huge architectural overhaul of this release. One thing this release features that Hurd still doesn't have: working sound support. For those unfamiliar with multi-server systems, the project has a brief conceptual overview document.

Pankaj Kumar writes "Controversies aside, JBoss has emerged as a credible alternative to commercial J2EE App Servers for developing and deploying Java based server applications. Besides the usual advantages of open source and GPL licensing, what sets it apart is its JMX based microkernel, a light-weight framework to run independently developed Java programs within a single JVM. Together, these make it possible for one to pick and choose components and assemble a custom server anywhere between the two extremes (and beyond!) of a simple Servlet Container and a full-fledged J2EE Server. JBoss - A Developer's Notebook by Norman Richards, a JBoss developer at JBoss, Inc., and Sam Griffith, Jr., a software consultant and trainer, is a no-fluff How-To guide on doing stuff with JBoss in O'Reilly's new Developer Notebook format." Read on for Kumar's review of the book.

JayBonci writes "It may come as a surprise that within the pages of 'Perl 6 Essentials' lies what could be two books, despite its length. If not for lack of cover space, it could easily bear the names "Perl6 for Perl5 programmers" and "Parrot in a Nutshell". Both topics are concise and clearly covered, despite their relatively different audience." Read on for the rest of Jay's review.

Chris Worth has come to me (surprise!) with a review of one of the most definitive books on nanotechnology, Nanosystems. K. Eric Drexler's response to the technical issues raised by critics to nanotechnology, the book is a technical treatise
