This volume contains the papers presented at the Eighth International C- ference on Logic for Programming, Arti?cial Intelligence and Reasoning (LPAR 2001), held on December 3-7, 2001, at the University of Havana (Cuba), together with the Second International Workshop on Implementation of Logics. There were 112 submissions, of which 19 belonged to the special subm- sion category of experimental papers, intended to describe implementations or comparisons of systems, or experiments with systems. Each submission was - viewed by at least three program committee members and an electronic program committee meeting was held via the Internet. The high number of submissions caused a large amount of work, and we are very grateful to the other 31 PC members for their e?ciency and for the quality of their reviews and discussions. Finally, the committee decided to accept 40papers in the theoretical ca- gory, and 9 experimental papers. In addition to the refereed papers, this volume contains an extended abstract of the invited talk by Frank Wolter. Two other invited lectures were given by Matthias Baaz and Manuel Hermenegildo. Apart from the program committee, we would also like to thank the other people who made LPAR 2001 possible: the additional referees; the Local Arran- ` gements Chair Luciano Garc ́?a; Andr ́es Navarro and Oscar Guell, ̈ who ran the internet-based submission software and the program committee discussion so- ware at the LSI Department lab in Barcelona; and Bill McCune, whose program committee management software was used.

One Zentangle A Day is a beautiful interactive book teaching the principles of Zentangles as well as offering fun, related drawing exercises. Zentangles are a new trend in the drawing and paper arts world. The concept was started by Rick Roberts and Maria Thomas as a way to practice focus and meditation through drawing, by using repetitive lines, marks, circles, and shapes. Each mark is called a "tangle," and you combine various tangles into patterns to create "tiles" or small square drawings. This step-by-step book is divided into 6 chapters, each with 7 daily exercises. Each exercise includes new tangles to draw in sketchbooks, teaches daily tile design, and offers tips on related art principles, and contains an inspirational "ZIA" (Zentangle Inspired Art) project on a tile that incorporates patterns, art principals, and new techniques.

This open access two-volume set LNCS 10980 and 10981 constitutes the refereed proceedings of the 30th International Conference on Computer Aided Verification, CAV 2018, held in Oxford, UK, in July 2018. The 52 full and 13 tool papers presented together with 3 invited papers and 2 tutorials were carefully reviewed and selected from 215 submissions. The papers cover a wide range of topics and techniques, from algorithmic and logical foundations of verification to practical applications in distributed, networked, cyber-physical, and autonomous systems. They are organized in topical sections on model checking, program analysis using polyhedra, synthesis, learning, runtime verification, hybrid and timed systems, tools, probabilistic systems, static analysis, theory and security, SAT, SMT and decisions procedures, concurrency, and CPS, hardware, industrial applications.

"Imagine trying to play defense in football without ever studying offense. You would not know when a run was coming, how to defend pass patterns, nor when to blitz. In computer systems, as in football, a defender must be able to think like an attacker. I say it in my class every semester, you don't want to be the last person to attack your own system--you should be the first. "The world is quickly going online. While I caution against online voting, it is clear that online gaming is taking the Internet by storm. In our new age where virtual items carry real dollar value, and fortunes are won and lost over items that do not really exist, the new threats to the intrepid gamer are all too real. To protect against these hazards, you must understand them, and this groundbreaking book is the only comprehensive source of information on how to exploit computer games. Every White Hat should read it. It's their only hope of staying only one step behind the bad guys." --Aviel D. Rubin, Ph.D. Professor, Computer Science Technical Director, Information Security Institute Johns Hopkins University "Everyone's talking about virtual worlds. But no one's talking about virtual-world security. Greg Hoglund and Gary McGraw are the perfect pair to show just how vulnerable these online games can be." --Cade Metz Senior Editor PC Magazine "If we're going to improve our security practices, frank discussions like the ones in this book are the only way forward. Or as the authors of this book might say, when you're facing off against Heinous Demons of Insecurity, you need experienced companions, not to mention a Vorpal Sword of Security Knowledge." --Edward W. Felten, Ph.D. Professor of Computer Science and Public Affairs Director, Center for Information Technology Policy Princeton University "Historically, games have been used by warfighters to develop new capabilities and to hone existing skills--especially in the Air Force. The authors turn this simple concept on itself, making games themselves the subject and target of the 'hacking game,'and along the way creating a masterly publication that is as meaningful to the gamer as it is to the serious security system professional. "Massively distributed systems will define the software field of play for at least the next quarter century. Understanding how they work is important, but understanding how they can be manipulated is essential for the security professional. This book provides the cornerstone for that knowledge." --Daniel McGarvey Chief, Information Protection Directorate United States Air Force "Like a lot of kids, Gary and I came to computing (and later to computer security) through games. At first, we were fascinated with playing games on our Apple ][s, but then became bored with the few games we could afford. We tried copying each other's games, but ran up against copy-protection schemes. So we set out to understand those schemes and how they could be defeated. Pretty quickly, we realized that it was a lot more fun to disassemble and work around the protections in a game than it was to play it. "With the thriving economies of today's online games, people not only have the classic hacker's motivation to understand and bypass the security of games, but also the criminal motivation of cold, hard cash. That's a combination that's hard to stop. The first step, taken by this book, is revealing the techniques that are being used today." --Greg Morrisett, Ph.D. Allen B. Cutting Professor of Computer Science School of Engineering and Applied Sciences Harvard University "If you're playing online games today and you don't understand security, you're at a real disadvantage. If you're designing the massive distributed systems of tomorrow and you don't learn from games, you're just plain sunk." --Brian Chess, Ph.D. Founder/Chief Scientist, Fortify Software Coauthor ofSecure Programming with Static Analysis "This book offers up a fascinating tour of the battle for software security on a whole new front: attacking an online game. Newcomers will find it incredibly eye opening and even veterans of the field will enjoy some of the same old programming mistakes given brilliant new light in a way that only massively-multiplayer-supermega-blow-em-up games can deliver. w00t!" --Pravir Chandra Principal Consultant, Cigital Coauthor ofNetwork Security with OpenSSL If you are a gamer, a game developer, a software security professional, or an interested bystander, this book exposes the inner workings of online-game security for all to see. From the authors of the best-selling Exploiting Software, Exploiting Online Gamestakes a frank look at controversial security issues surrounding MMORPGs, such as World of Warcraftand Second Life. This no-holds-barred book comes fully loaded with code examples, debuggers, bots, and hacks. This book covers Why online games are a harbinger of software security issues to come How millions of gamers have created billion-dollar virtual economies How game companies invade personal privacy Why some gamers cheat Techniques for breaking online game security How to build a bot to play a game for you Methods for total conversion and advanced mods Written by the world's foremost software security experts, this book takes a close look at security problems associated with advanced, massively distributed software. With hundreds of thousands of interacting users, today's online games are a bellwether of modern software. The kinds of attack and defense techniques described in Exploiting Online Gamesare tomorrow's security techniques on display today.
