The planet Lusitania is home to three sentient species: the Pequeninos; a large colony of humans; and the Hive Queen, brought there by Ender. But once against the human race has grown fearful; the Starways Congress has gathered a fleet to destroy Lusitania.

Jane, the evolved computer intelligence, can save the three sentient races of Lusitania. She has learned how to move ships outside the universe, and then instantly back to a different world, abolishing the light-speed limit. But it takes all the processing power available to her, and the Starways Congress is shutting down the Net, world by world.

Soon Jane will not be able to move the ships. Ender's children must save her if they are to save themselves.

In the aftermath of his terrible war, Ender Wiggin disappeared, and a powerful voice arose: The Speaker for the Dead, who told the true story of the Bugger War.

Now, long years later, a second alien race has been discovered, but again the aliens' ways are strange and frightening...again, humans die. And it is only the Speaker for the Dead, who is also Ender Wiggin the Xenocide, who has the courage to confront the mystery...and the truth.

The war for survival of the planet Lusitania will be fought in the hearts of a child named Gloriously Bright.

On Lusitania, Ender found a world where humans and pequininos and the Hive Queen could all live together; where three very different intelligent species could find common ground at last. Or so he thought.

Lusitania also harbors the descolada, a virus that kills all humans it infects, but which the pequininos require in order to become adults. The Startways Congress so fears the effects of the descolada, should it escape from Lusitania, that they have ordered eh destruction of the entire planet, and all who live there. The Fleet is on its way, a second xenocide seems inevitble.

A provocative, insightful explanation for why it is that belief—not religion—keeps us in a perilous state of willful ignorance

In The Religious Case Against Belief, James Carse identifies the twenty-first century’s most forbidding villain: belief. In distinguishing religions from belief systems, Carse works to reveal how belief—with its restriction on thought and encouragement of hostility—has corrupted religion and spawned violence the world over.

Galileo, Martin Luther, Abraham Lincoln, and Jesus Christ—using their stories Carse creates his own brand of parable and establishes a new vocabulary with which to study conflict in the modern world. The Religious Case Against Belief introduces three kinds of ignorance: ordinary ignorance (a mundane lack of knowledge, such as ignorance of tomorrow’s weather or the reason why your stove is malfunctioning), willful ignorance (an intentional avoidance of accessible knowledge), and finally higher ignorance (a learned understanding that no matter how many truths we may accumulate, our knowledge falls infinitely short of the truth).

While ordinary ignorance is common to all people, Carse associates the strongest manifestation of willful ignorance with the most fervent (and dangerous) of believers. He points to the historic conflict between Martin Luther and Holy Roman Emperor Charles V both to reveal this seemingly religious collision as a clash of belief and to identify belief ’s inherently destructive characteristics. From Luther to the contemporary Christian right, we learn that believers construct identity by erecting boundaries and by fostering aggression between the believer and the other. This is why belief systems choose—at great cost—to remain locked in bloody conflict rather than to engage in dialogue, recognizing the great deal they have in common. This is willful ignorance.

In fierce contrast to willful ignorance, higher ignorance is an acquired state enhanced by religion. Those traveling the path to higher ignorance recognize faith teachings (such as the Bible) as poetry intended to promote contemplation, interpretation, and a sense of wonder. For evidence of religion’s deeply embedded rejection of singular truth and its acceptance of diverse dialogue, Carse looks to the many faces of Jesus presented in the books of the Bible and elsewhere. Uncontaminated by belief systems, religion rejects the imagined boundaries that falsely divide people and ideas, working to expand horizons.

The Religious Case Against Belief exposes a world in which religion and belief have become erroneously (and terrifyingly) conflated. In strengthening their association with powerful belief systems, religions have departed from their essential purpose as agencies of higher ignorance. Carse uses his wideranging understanding of religion to find a viable and vital path away from what he calls the Age of Faith II and toward open-ended global dialogue. Far from abstract philosophical musing, The Religious Case Against Belief is required reading for our age.

Hackers Beware starts with a roadmap of the various areas of hacking but quickly delves into the details of how specific attacks work and how to protect against them. Since most attacks we hear about either occur or are perceived to come from hackers, people are very interested "in how they do that" - the techniques hackers use to break into systems. Hackers Beware is unique in that it gives specific exploits, exactly how they work and how to protect against them. This book will help readers understand what security threats they are up against and what they need to do to protect against them. Some books cover this from a high level but do not get into the details of specific exploits and cover it in a case by case fashion. This book will cover the complete picture. It will not only describe how an exploit works but present the signature of the attack, what to look for on a network and how to protect against it.

This best-selling, conceptual introduction to TCP/IP internetworking protocols interweaves a clear discussion of fundamentals with the latest technologies. Leading author Doug Comer covers layering and shows how all protocols in the TCP/IP suite fit into the five-layer model. With a new focus on CIDR addressing, this revision addresses MPLS and IP switching technology, traffic scheduling, VOIP, Explicit Congestion Notification (ECN), and Selective ACKnowledgement (SACK). Includes coverage of Voice and Video Over IP (RTP), IP coverage, a discussion of routing architectures, examination of Internet application services such as domain name system (DNS), electronic mail (SMTP, MIME), file transfer and access (FTP, TFTP, NFS), remote login (TELNET, rlogin), and network management (SNMP, MIB, ANS.I), a description of mobile IP, and private network interconnections such as NAT and VPN. The new edition includes updates to every chapter, updated examples, a new chapter on MPLS and IP switching technology and an expanded TCP description that featuers Explicit Congestion Notification (ECN) and Selective ACKnowledgement (SACK). For network and web designers, implementers, and administrators, and for anyone interested in how the Internet works.

Information overload. If you're responsible for maintaining your network's security, you're living with it every day. Logs, alerts, packet captures, and even binary files take time and effort to analyze using text-based tools - and once your analysis is complete, the picture isn't always clear, or timely. And time is of the essence.

Information visualization is a branch of computer science concerned with modeling complex data using interactive images. When applied to network data, these interactive graphics allow administrators to quickly analyze, understand, and respond to emerging threats and vulnerabilities.

Security Data Visualization is a well-researched and richly illustrated introduction to the field. Greg Conti, creator of the network and security visualization tool RUMINT, shows you how to graph and display network data using a variety of tools so that you can understand complex datasets at a glance. And once you've seen what a network attack looks like, you'll have a better understanding of its low-level behavior - like how vulnerabilities are exploited and how worms and viruses propagate.

You'll learn how to use visualization techniques to:

Audit your network for vulnerabilities using free visualization tools, such as AfterGlow and RUMINTSee the underlying structure of a text file and explore the faulty security behavior of a Microsoft Word documentGain insight into large amounts of low-level packet dataIdentify and dissect port scans, Nessus vulnerability assessments, and Metasploit attacksView the global spread of the Sony rootkit, analyze antivirus effectiveness, and monitor widespread network attacksView and analyze firewall and intrusion detection system (IDS) logs

Security visualization systems display data in ways that are illuminating to both professionals and amateurs. Once you've finished reading this book, you'll understand how visualization can make your response to security threats faster and more effective
