Andreas Zeller – författare

Why Programs Fail is about bugs in computer programs, how to find them, how to reproduce them, and how to fix them in such a way that they do not occur anymore. This is the first comprehensive book on systematic debugging and covers a wide range of tools and techniques ranging from hands-on observation to fully automated diagnoses, and includes instructions for building automated debuggers. This discussion is built upon a solid theory of how failures occur, rather than relying on seat-of-the-pants techniques, which are of little help with large software systems or to those learning to program. The author, Andreas Zeller, is well known in the programming community for creating the GNU Data Display Debugger (DDD), a tool that visualizes the data structures of a program while it is running.- Winner of a 2006 Jolt Productivity Award for Technical Books- Shows how to reproduce software failures faithfully, how to isolate what is important about the failure, and to discover what caused it- Describes how to fix the program in the best possible way, and shows how to create your own automated debugging tools- Includes exercises and extensive references for further study

Why Programs Fail: A Guide to Systematic Debugging is proof that debugging has graduated from a black art to a systematic discipline. It demystifies one of the toughest aspects of software programming, showing clearly how to discover what caused software failures, and fix them with minimal muss and fuss.The fully updated second edition includes 100+ pages of new material, including new chapters on Verifying Code, Predicting Erors, and Preventing Errors. Cutting-edge tools such as FindBUGS and AGITAR are explained, techniques from integrated environments like Jazz.net are highlighted, and all-new demos with ESC/Java and Spec#, Eclipse and Mozilla are included.This complete and pragmatic overview of debugging is authored by Andreas Zeller, the talented researcher who developed the GNU Data Display Debugger(DDD), a tool that over 250,000 professionals use to visualize the data structures of programs while they are running. Unlike other books on debugging, Zeller''s text is product agnostic, appropriate for all programming languages and skill levels.The book explains best practices ranging from systematically tracking error reports, to observing symptoms, reproducing errors, and correcting defects. It covers a wide range of tools and techniques from hands-on observation to fully automated diagnoses, and also explores the author''s innovative techniques for isolating minimal input to reproduce an error and for tracking cause and effect through a program. It even includes instructions on how to create automated debugging tools.The text includes exercises and extensive references for further study, and a companion website with source code for all examples and additional debugging resources is available.- The new edition of this award-winning productivity-booster is for any developer who has ever been frustrated by elusive bugs- Brand new chapters demonstrate cutting-edge debugging techniques and tools, enabling readers to put the latest time-saving developments to work for them- Learn by doing. New exercises and detailed examples focus on emerging tools, languages and environments, including AGITAR, FindBUGS, Python and Eclipse

Im jungen schweizerischen Bundesstaat waren es die kirchlich Liberalen, die wesentlich daran beteiligt waren, dass der Artikel zur Glaubensfreiheit in der Bundesverfassung von 1874 angenommen wurde. Sie trugen damit zum Religionsfrieden bei und förderten den aufgeklärten historisch­-kri­tischen Umgang mit Bibel und Tradition. Dabei suchten liberale Theologinnen und Theologen immer wieder die Nähe zu anderen Wissensgebieten. In Offenheit und Toleranz wollten sie einen Beitrag leisten für ein gelingendes Zusammenleben in der Gesellschaft, zum Beispiel in der Förderung des interreligiösen Dialogs.Engagiert und detailliert entfaltet Andreas Zeller die Geschichte der kirchlich Liberalen in der reformierten Kirche im Kanton Bern mit Schwerpunkt auf den letzten 40 Jahren. Er stellt prägende Per­sonen, wegweisende Auseinandersetzungen und wichtige Institutionen vor. Ein Blick zurück und zugleich ein Blick voraus, der das Motto der Liberalen konkret werden lässt: liberal – reformiert – offen.

ETAPS 2006 was the ninth instance of the European Joint Conferences on Theory and Practice of Software. ETAPS is an annual federated conference that was established in 1998 by combining a number of existing and new conferences. This year it comprised ?ve conferences (CC, ESOP, FASE, FOSSACS, TACAS), 18 satellite workshops (AC- CAT, AVIS, CMCS, COCV, DCC, EAAI, FESCA, FRCSS, GT-VMT, LDTA, MBT, QAPL, SC, SLAP, SPIN, TERMGRAPH, WITS and WRLA), two tutorials, and seven invited lectures (not including those that were speci?c to the satellite events). We - ceived over 550 submissions to the ?ve conferences this year, giving an overall acc- tance rate of 23%, with acceptance rates below 30% for each conference. Congratu- tions to all the authors who made it to the ?nal programme! I hope that most of the other authorsstill founda way of participatingin this excitingevent and I hope you will continue submitting. The events that comprise ETAPS address various aspects of the system devel- ment process, including speci?cation, design, implementation, analysis and impro- ment. The languages, methodologies and tools which support these activities are all well within its scope. Di?erent blends of theory and practice are represented, with an inclination towards theory with a practical motivation on the one hand and soundly based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware systems, and the emphasis on software is not intended to be exclusive.

This book constitutes the thoroughly refereed post proceedings of the 5th International Haifa Verification Conference, HVC 2009, held in Haifa, Israel in October 2009. The 11 revised full papers presented together with four abstracts of invited lectures were carefully reviewed and selected from 23 submissions. The papers address all current issues, challenges and future directions of verification for hardware, software, and hybrid systems and present academic research in the verification of systems, generally divided into two paradigms - formal verification and dynamic verification (testing).
