The most complete, authoritative technical guide to the FreeBSD kernel’s internal structure has now been extensively updated to cover all major improvements between Versions 5 and 11. Approximately one-third of this edition’s content is completely new, and another one-third has been extensively rewritten.

Three long-time FreeBSD project leaders begin with a concise overview of the FreeBSD kernel’s current design and implementation. Next, they cover the FreeBSD kernel from the system-call level down–from the interface to the kernel to the hardware. Explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing each significant system facility, including process management, security, virtual memory, the I/O system, filesystems, socket IPC, and networking.

This Second Edition

• Explains highly scalable and lightweight virtualization using FreeBSD jails, and virtual-machine acceleration with Xen and Virtio device paravirtualization

• Describes new security features such as Capsicum sandboxing and GELI cryptographic disk protection

• Fully covers NFSv4 and Open Solaris ZFS support

• Introduces FreeBSD’s enhanced volume management and new journaled soft updates

• Explains DTrace’s fine-grained process debugging/profiling

• Reflects major improvements to networking, wireless, and USB support

Readers can use this guide as both a working reference and an in-depth study of a leading contemporary, portable, open source operating system. Technical and sales support professionals will discover both FreeBSD’s capabilities and its limitations. Applications developers will learn how to effectively and efficiently interface with it; system administrators will learn how to maintain, tune, and configure it; and systems programmers will learn how to extend, enhance, and interface with it.

Marshall Kirk McKusick writes, consults, and teaches classes on UNIX- and BSD-related subjects. While at the University of California, Berkeley, he implemented the 4.2BSD fast filesystem. He was research computer scientist at the Berkeley Computer Systems Research Group (CSRG), overseeing development and release of 4.3BSD and 4.4BSD. He is a FreeBSD Foundation board member and a long-time FreeBSD committer. Twice president of the Usenix Association, he is also a member of ACM, IEEE, and AAAS.

George V. Neville-Neil hacks, writes, teaches, and consults on security, networking, and operating systems. A FreeBSD Foundation board member, he served on the FreeBSD Core Team for four years. Since 2004, he has written the “Kode Vicious” column for Queue and Communications of the ACM. He is vice chair of ACM’s Practitioner Board and a member of Usenix Association, ACM, IEEE, and AAAS.

Robert N.M. Watson is a University Lecturer in systems, security, and architecture in the Security Research Group at the University of Cambridge Computer Laboratory. He supervises advanced research in computer architecture, compilers, program analysis, operating systems, networking, and security. A FreeBSD Foundation board member, he served on the Core Team for ten years and has been a committer for fifteen years. He is a member of Usenix Association and ACM.

People worry that computers, robots, interstellar aliens, or Satan himself – brilliant, stealthy, ruthless creatures – may seize control of our world and destroy what’s uniquely valuable about the human race. Cultural Evolution and its Discontents shows that our cultural systems – especially those whose last names are "ism" – are already doing that, and doing it so adeptly that we seldom even notice. Like other parasites, they’ve blindly evolved to exploit us for their own survival. Creative arts and humanistic scholarship are our best tools for diagnosis and cure.

The assemblages of ideas that have survived, like the assemblages of biological cells that have survived, are the ones good at protecting and reproducing themselves. They aren’t necessarily the ones that guide us toward our most admirable selves or our healthiest future. Relying so heavily on culture to protect our uniquely open minds from cognitive overload makes us vulnerable to hijacking by the systems that co-evolve with us.

Recognizing the selfish Darwinian functions of these systems makes sense of many aspects of history, politics, economics, and popular culture. What drove the Protestant Reformation? Why have the Beatles, The Hunger Games, and paranoid science-fiction thrived, and how was hip-hop co-opted? What alliances helped neoliberalism out-compete Communism, and what alliances might enable environmentalism to overcome consumerism? Why are multiculturalism and university-trained elites provoking working-class nationalist backlash? In a digital age, how can we use numbers without having them use us instead?

Anyone who has wondered how our species can be so brilliant and so stupid at the same time may find an answer here: human mentalities are so complex that we crave the simplifications provided by our cultures, but the cultures that thrive are the ones that blind us to any interests that don’t correspond to their own.

This book is a unique volume that brings a variety of psychoanalytic perspectives to the study of sport. It highlights the importance of sports for different individuals and how the function and use of sports can be brought into the consulting room.

Passionate interest in actively engaging in sports is a universal phenomenon. It is striking that this aspect of human life, prior to this volume, has received little attention in the literature of psychoanalysis. This edited volume is comprised largely of psychoanalysts who are themselves avidly involved with sports. It is suggested that intense involvement in sports prioritizes commitment and active engagement over passivity and that such involvement provides an emotionally tinged distraction from the various misfortunes of life. Indeed, the ups and downs in mood related to athletic victory or defeat often supplant, temporarily, matters in life that may be more personally urgent. Engaging in sports or rooting for teams provides a feeling of community and a sense of identification with like-minded others, even among those who are part of other communities and have sufficient communal identifications.

This book offers a better psychoanalytic understanding of sports to help us discover more about ourselves, our patients and our culture, and will be of great interest to psychotherapists and psychoanalysts, or anyone with an interest in sport and its link to psychoanalysis and mental health.
