In Hacker’s Delight, Second Edition, Hank Warren once again compiles an irresistible collection of programming hacks: timesaving techniques, algorithms, and tricks that help programmers build more elegant and efficient software, while also gaining deeper insights into their craft. Warren’s hacks are eminently practical, but they’re also intrinsically interesting, and sometimes unexpected, much like the solution to a great puzzle. They are, in a word, a delight to any programmer who is excited by the opportunity to improve. Extensive additions in this edition include A new chapter on cyclic redundancy checking (CRC), including routines for the commonly used CRC-32 code A new chapter on error correcting codes (ECC), including routines for the Hamming code More coverage of integer division by constants, including methods using only shifts and adds Computing remainders without computing a quotient More coverage of population count and counting leading zeros Array population count New algorithms for compress and expand An LRU algorithm Floating-point to/from integer conversions Approximate floating-point reciprocal square root routine A gallery of graphs of discrete functions Now with exercises and answers
This book provides an in-depth exploration of the phenomenon of hacking from a multidisciplinary perspective that addresses the social and technological aspects of this unique activity as well as its impact. • Documents how computer hacking fits into various forms of cybercrime • Describes the subculture of computer hackers and explains how this social world plays an integral role in the business of hacking • Clarifies the subtle differences between ethical and malicious hacks • Focuses on the non-technical aspects of computer hacking to enable the reader to better understand the actors and their motives

Duality of subsequences and maps between them are discussed and explicit proofs are shown in detail. From the Content Basic structural and enumerative properties of Farey sequences, Collective decision making, Committee methods in pattern recognition, Farey duality, Farey sequence, Fundamental Farey subsequences, Monotone bijections between Farey subsequences
Master Modern Networking by Understanding and Solving Real Problems Computer Networking Problems and Solutions offers a new approach to understanding networking that not only illuminates current systems but prepares readers for whatever comes next. Its problem-solving approach reveals why modern computer networks and protocols are designed as they are, by explaining the problems any protocol or system must overcome, considering common solutions, and showing how those solutions have been implemented in new and mature protocols. Part I considers data transport (the data plane). Part II covers protocols used to discover and use topology and reachability information (the control plane). Part III considers several common network designs and architectures, including data center fabrics, MPLS cores, and modern Software-Defined Wide Area Networks (SD-WAN). Principles that underlie technologies such as Software Defined Networks (SDNs) are considered throughout, as solutions to problems faced by all networking technologies. This guide is ideal for beginning network engineers, students of computer networking, and experienced engineers seeking a deeper understanding of the technologies they use every day. Whatever your background, this book will help you quickly recognize problems and solutions that constantly recur, and apply this knowledge to new technologies and environments. Coverage Includes · Data and networking transport · Lower- and higher-level transports and interlayer discovery · Packet switching · Quality of Service (QoS) · Virtualized networks and services · Network topology discovery · Unicast loop free routing · Reacting to topology changes · Distance vector control planes, link state, and path vector control · Control plane policies and centralization · Failure domains · Securing networks and transport · Network design patterns · Redundancy and resiliency · Troubleshooting · Network disaggregation · Automating network management · Cloud computing · Networking the Internet of Things (IoT) · Emerging trends and technologies
Walter De Maria's Lightning Field (1977) is one of the 20th century's most significant works of art. Situated in a remote area of desert in southwestern New Mexico, it comprises 400 polished, stainless-steel poles (spaced 220 feet apart) installed in a grid measuring one mile by one kilometer. A sculpture to be explored on foot, The Lightning Field is intended to be experienced over an extended period of time. Critic Kenneth Baker visited The Lightning Field numerous times over the course of the past 30 years in order to write this text. Inspired and challenged by this remarkable artwork, Baker speculates on the course of our contemporary human condition. But, rather than building on ideas in narrative sequence, he deploys quotation to effect multiple perspectives and points of view. Baker's citations and elegantly crafted prose are arrayed––in a metaphorical parallel to De Maria's choreographing of the vast landscape of the American Southwest––to create a compelling text.
