If you’ve ever been responsible for a network, you know that sinking feeling: your pager has gone off at 2 a.m., the network is broken, and you can’t figure out why by using a dial-in connection from home. You drive into the office, dig out your protocol analyzer, and spend the next four hours trying to put things back together before the staff shows up for work.
When this happens, you often find yourself looking at the low-level guts of the Internet protocols: you’re deciphering individual packets, trying to figure out what is (or isn’t) happening. Until now, the only real guide to the protocols has been the Internet RFCs—and they’re hardly what you want to be reading late at night when your network is down. There hasn’t been a good book on the fundamentals of IP networking aimed at network administrators—until now.
Internet Core Protocols: The Definitive Guide contains all the information you need for low-level network debugging. It provides thorough coverage of the fundamental protocols in the TCP/IP suite: IP, TCP, UDP, ICMP, ARP (in its many variations), and IGMP. (The companion volume, Internet Application Protocols: The Definitive Guide, provides detailed information about the commonly used application protocols, including HTTP, FTP, DNS, POP3, and many others). It includes many packet captures, showing you what to look for and how to interpret all the fields. It has been brought up to date with the latest developments in real-world IP networking.
The CD-ROM included with the book contains Shomiti’s “Surveyor Lite,” a packet analyzer that runs on Win32 systems, plus the original RFCs, should you need them for reference. Together, this package includes everything you need to troubleshoot your network—except coffee.
Mark S. Gockenbach - Understanding and Implementing the Finite Element Method
The ﬁnite element method is the most powerful general-purpose technique for computing accurate solutions to partial differential equations. Understanding and Implementing the Finite Element Method is essential reading for those interested in understanding both the theory and the implementation of the ﬁnite element method for equilibrium problems. This book contains a thorough derivation of the finite element equations as well as sections on programming the necessary calculations, solving the finite element equations, and using a posteriori error estimates to produce validated solutions. Accessible introductions to advanced topics, such as multigrid solvers, the hierarchical basis conjugate gradient method, and adaptive mesh generation, are provided. Each chapter ends with exercises to help readers master these topics. Understanding and Implementing the Finite Element Method includes a carefully documented collection of MATLAB® programs implementing the ideas presented in the book. Readers will beneﬁt from a careful explanation of data structures and speciﬁc coding strategies and will learn how to write a ﬁnite element code from scratch. Students can use the MATLAB codes to experiment with the method and extend them in various ways to learn more about programming ﬁnite elements. This practical book should provide an excellent foundation for those who wish to delve into advanced texts on the subject, including advanced undergraduates and beginning graduate students in mathematics, engineering, and the physical sciences.

Chris Melissinos - The Art of Video Games
In the forty years since the first Magnavox Odyssey pixel winked on in 1972, the home video game industry has undergone a mind-blowing evolution. Fueled by unprecedented advances in technology, boundless imaginations, and an insatiable addiction to fantastic new worlds of play, the video game has gone supernova, rocketing two generations of fans into an ever-expanding universe where art, culture, reality, and emotion collide. As a testament to the cultural impact of the game industry's mega morph, the Smithsonian American Art Museum, with curator and author Chris Melissinos, conceived the forthcoming exhibition, The Art of Video Games, which will run from March 16 to September 30, 2012.* New York publisher Welcome Books will release the companion book this March. Melissinos presents video games as not just mere play, but richly textured emotional and social experiences that have crossed the boundary into culture and art. Along with a team of game developers, designers, and journalists, Melissinos chose a pool of 240 games across five different eras to represent the diversity of the game world. Criteria included visual effects, creative use of technologies, and how world events and popular culture manifested in the games. The museum then invited the public to go online to help choose the games. More than 3.7 million votes (from 175 countries) later, the eighty winners featured in The Art of Video Games exhibition and book were selected. From the Space Invaders of the seventies to sophisticated contemporary epics BioShock and Uncharted 2, Melissinos examines each of the winning games, providing a behind-the-scenes look at their development and innovation, and commentary on the relevance of each in the history of video games. Over 100 composite images, created by Patrick O'Rourke, and drawn directly from the games themselves, illustrate the evolution of video games as an artistic medium, both technologically and creatively. Additionally, The Art of Video Games includes fascinating interviews with influential artists and designers—from pioneers such as Nolan Bushnell to contemporary innovators including Warren Spector, Tim Schafer and Robin Hunicke. The foreword was written by Elizabeth Broun, director of the Smithsonian American Art Museum and Mike Mika, noted game preservationist and prolific developer, contributed the introduction. *After Washington D.C., the exhibition travels to several cities across the United States, including Boca Raton (Museum of Art), Seattle (EMP Museum), Yonkers, NY (Hudson River Museum) and Flint, MI (Flint Institute of Arts).

Kazári Csaba - Hacker, cracker, warez
Ez a könyv egyrészt hackerek és crackerek története, illegális programok terjesztőiről és készítőiről szól: ők mondják el a véleményüket, mesélnek magukról, szakmájukról, programjaikról, eddig elkövetett kisebb-nagyobb "botlásaikról" - kibővítve természetesen azon fejezetekkel, ahol a számítástechnikai és a gyakorlati részeket vesézzük ki alaposan. Másrészt egy újságíró története is, aki több mint négy hónapot töltött el ezeknek az embereknek a társaságában, figyelve, jegyzetelve, interjúkat készítve, óvatosan elmerészkedve addig a határig, ameddig egy újságírót még enged a jog és a jóérzés.

Hogyan képzeltük el a jövőnket? És mi lett helyette? Hogyan működnek a jövőkutatók? Mik azok, amiket nem jósoltak meg, de megkaptunk? Milyen egy közösségi oldal az üzemeltetők oldaláról? Hogyan értjük a zenét, más kultúrákat és egymást? Milyen kulturális mozgalmak vannak a Tron és a Mátrix mögött? És tényleg van internetkapcsolat a Föld és a Mars között? Ezek a könyv legártatlanabb kérdései.
Kevin Mitnick - William L. Simon - Ghost in the Wires
Kevin Mitnick was the most elusive computer break-in artist in history. He accessed computers and networks at the world's biggest companies--and however fast the authorities were, Mitnick was faster, sprinting through phone switches, computer systems, and cellular networks. He spent years skipping through cyberspace, always three steps ahead and labeled unstoppable. But for Kevin, hacking wasn't just about technological feats-it was an old fashioned confidence game that required guile and deception to trick the unwitting out of valuable information. Driven by a powerful urge to accomplish the impossible, Mitnick bypassed security systems and blazed into major organizations including Motorola, Sun Microsystems, and Pacific Bell. But as the FBI's net began to tighten, Kevin went on the run, engaging in an increasingly sophisticated cat and mouse game that led through false identities, a host of cities, plenty of close shaves, and an ultimate showdown with the Feds, who would stop at nothing to bring him down. Ghost in the Wires is a thrilling true story of intrigue, suspense, and unbelievable escape, and a portrait of a visionary whose creativity, skills, and persistence forced the authorities to rethink the way they pursued him, inspiring ripples that brought permanent changes in the way people and companies protect their most sensitive information.
