Homelessness has become a lasting issue of vital social concern. As the number of the homeless has grown, the complexity of the issue has become increasingly clear to researchers and private and public service providers. The plight of the homeless raises many ethical, anthropological, political, sociological, and public health questions. The most serious and perplexing of these questions is what steps private, charitable, and public organizations can take to alleviate and eventually solve the problem. The concept of homelessness is difficult to define and measure. Generally, persons are thought to be homeless if they have no permanent residence and seek security, rest, and protection from the elements. The homeless typically live in areas that are not designed to be shelters (e.g., parks, bus terminals, under bridges, in cars), occupy structures without permission (e.g., squatters), or are provided emergency shelter by a public or private agency. Some definitions of homelessness include persons living on a short-term basis in single-room-occupancy hotels or motels, or temporarily residing in social or health-service facilities without a permanent address. Housing the Homeless is a collection of case studies that bring together a variety of perspectives to help develop a clear understanding of the homelessness problem. The editors include information on the background and politics of the problem and descriptions of the current homeless population. The book concludes with a resource section, which highlights governmental policies and programs established to deal with the problem of homelessness.

Hacking is the art of creative problem solving, whether that means finding an unconventional solution to a difficult problem or exploiting holes in sloppy programming. Many people call themselves hackers, but few have the strong technical foundation needed to really push the envelope. Rather than merely showing how to run existing exploits, author Jon Erickson explains how arcane hacking techniques actually work. To share the art and science of hacking in a way that is accessible to everyone, Hacking: The Art of Exploitation, 2nd Edition introduces the fundamentals of C programming from a hacker's perspective. The included LiveCD provides a complete Linux programming and debugging environment-all without modifying your current operating system. Use it to follow along with the book's examples as you fill gaps in your knowledge and explore hacking techniques on your own. Get your hands dirty debugging code, overflowing buffers, hijacking network communications, bypassing protections, exploiting cryptographic weaknesses, and perhaps even inventing new exploits. This book will teach you how to: Program computers using C, assembly language, and shell scripts; Corrupt system memory to run arbitrary code using buffer overflows and format string; Inspect processor registers and system memory with a debugger to gain a real understanding of what is happening; Outsmart common security measures like nonexecutable stacks and intrusion detection systems; Gain access to a remote server using port-binding or connect-back shellcode, and alter a server's logging behaviour to hide your presence; Redirect network traffic, conceal open ports, and hijack TCP connections; Crack encrypted wireless traffic using the FMS attack, and speed up brute-force attacks using a password probability matrix Hackers are always pushing the boundaries, investigating the unknown, and evolving their art. Even if you don't already know how to program, Hacking: The Art of Exploitation, 2nd Edition will give you a complete picture of programming, machine architecture, network communications, and existing hacking techniques. Combine this knowledge with the included Linux environment, and all you need is your own creativity.
