From Flipper to SeaWorld, dolphins have long captured our hearts. We love these friendly, intelligent mammals, and they seem to return our feelings—they enjoy interacting with swimmers and have been known to encircle people under attack by sharks. Despite our familiarity with dolphins, though, we remain ill-informed about how they evolved, how they function, and how they have interacted with humans for millennia. Dolphin dives into the dolphin’s zoology, as well as its social and cultural history, to offer a comprehensive view of these delightful creatures. Drawing on his years of experience working with and studying dolphins, Alan Rauch explores their propensity to live in pods and their ability to communicate through a variety of clicks, whistles, and other vocalizations. He examines their long relationship with humans, describing how they became the emblem of safe travel and charity, that the ancient Greeks featured them on coins, and that Hindu mythology associated them with Ganga, a river deity. As the rise in popularity of dolphinaria during the 1960s allowed the public access to dolphins, they became central characters in films like The Day of the Dolphin and Johnny Mnemonic and outsmarted humans in The Hitchhiker’s Guide to the Galaxy. Packed with images and thoughtful insights, Dolphin is a revealing look at one of our favorite sea creatures.

After introducing the concept of the birthing pool in the 1970s, Michel Odent has continuously expanded his interest in the mysterious connections between humans and water. In Planet Ocean he shows that the evolution of the oceans – particularly the fluctuations of sea levels – and the evolution of humans are inseparable. The oceans are the givers and sustainers of life, holding ninety-five per cent of the planet’s habitable space within their immense depths. Odent steers us towards a radically new vision of human nature. Our defining feature – a supersized brain – becomes a leitmotif that enables links between topics as diverse as our nutritional needs, our relationship with sea mammals, and the way members of our species give birth. He relates ‘transcendent emotional states’ with what the French writer Romain Rolland referred to as ‘the oceanic feeling’ – both suggesting the absence of limits. Access to such states can be associated with, for example, a ‘foetus ejection reflex’. This leads to the extraordinary conclusion that swimming – as learnt behaviour among humans – the birth process and access to transcendence are interrelated topics for students of human nature. Planet Ocean is a fascinating interdisciplinary study that demonstrates our manifold connections to water and suggests their relevance to everyday life.

This book covers what an administrator needs to plan out and integrate a DMZ into a network for small, medium and Enterprise networks. In most enterprises the perception is that a firewall provides a hardened perimeter. However, the security of internal networks and hosts is usually very soft. In such an environment, a non-DMZ system that is offering services to the Internet creates the opportunity to leapfrog to other hosts in the soft interior of your network. In this scenario your internal network is fair game for any attacker who manages to penetrate your so-called hard perimeter. - There are currently no books written specifically on DMZs - This book will be unique in that it will be the only book that teaches readers how to build a DMZ using all of these products: ISA Server, Check Point NG, Cisco Routers, Sun Servers, and Nokia Security Appliances. - Dr. Thomas W. Shinder is the author of the best-selling book on Microsoft's ISA, Configuring ISA Server 2000. Customers of the first book will certainly buy this book.
