Converting a brilliant and specially customized C or C++ application from a generic UNIX OS to GNU/Linux has the potential to be painful, costly and time consuming. From comical personal experience I find that Murphy smiles and laughs at such rich complexities. “UNIX to Linux Porting: A Comprehensive Reference” gives psychological handle bars for those of you that wish to plan or enact a porting project for the first time and a comprehensive reference for the more experienced. This book details the main differences between Solaris, AIX, HP-UX and GNU/Linux.

In “Linux Patch Management”, Michael Jang describes in necessary detail how to achieve patch efficiency via tools such as apt-get, rpm and rsynch.

“User Mode Linux” by Jeff Dike discusses a specific form of virtualization. UML is a Linux virtual machine contained within the GNU/Linux operating environment. The technique allows you to run multiple sandboxed virtual instances of Linux from one machine under a master Linux operating system. This is always good for server consolidation, security and development. In this book, a potentially complex subject area has been tamed and discussed with well grounded commonsense and practical examples by the original creator and current maintainer of the software. Virtualization is a hot topic.
