As software systems become ubiquitous, the issues of dependability become more and more crucial. Given that solutions to these issues must be considered from the very beginning of the design process, it is reasonable that dependability is addressed at the architectural level. This book was born of an effort to bring together the research communities of software architectures and dependability.

This state-of-the-art survey contains expanded and peer-reviewed papers based on the carefully selected contributions to two workshops: the Workshop on Architecting Dependable Systems (WADS 2007), organized at the 2007 International Conference on Dependable Systems and Networks (DSN 2007), held in Edinburgh, UK in June 2007 and the Third Workshop on the Role of Software Architecture for Testing and Analysis (ROSATEA 2007) organized as part of a federated conference on Component-Based Software Engineering and Software Architecture (CompArch 2007), held in Medford, MA, USA in July 2007. It also contains a number of invited papers written by recognized experts in the area. The 14 papers are organized in topical sections on critical infrastructures, rigorous design/fault tolerance, and verification and validation.

This volume contains the proceedings of the 10th IFIP Working Group 6.1 - ternational Conference on Formal Methods for Open Object-Based Distributed Systems (FMOODS 2008).The conference was part of the Third Federated c- ferences on Distributed Computing Techniques (DisCoTec), together with the 10th International Conference on Coordination Models and Languages (COOR- DINATION 2008) and the 8th IFIP International Conference on Distributed Applications and Interoperable Systems (DAIS 2008). We are grateful to Frank Eliassen and Einar Broch Johnsen of the University of Oslo for the excellent organization of this event in Olso, Norway, June 4-6, 2008. The goal of the FMOODS conferences is to bring together researchers and practitioners whose work encompasses three important and related ?elds: - Formal methods - Distributed systems - Object-based technology The 14 papers presented at FMOODS 2008 and included in this volume were selected by the Program Committee among 35 submissions. Each submission was reviewed by at least three Program Committee members. They all re?ect thescopeoftheconferenceandcoverthe following topics: semantics of obje- oriented programming; formal techniques for speci?cation, analysis, and re?- ment; model checking; theorem proving and deductive veri?cation;type systems and behavioral typing; formal methods for service-oriented computing; integ- tion of quality of service requirements into formal models; formal approaches to component-based design; and applications of formal methods.

This volume contains the proceedings of FORTE 2008, 28th IFIP WG6.1 - ternational Conference on Formal Techniques for Networked and Distributed Systems. FORTE 2008 was held at the Campus Innovation Center in Tokyo, Japan during June 10-13, 2008. FORTE denotes a series of international wo- ing conferences on formal description techniques applied to computer networks and distributed systems. The conference series started in 1981 under the name PSTV. In 1988 a second series under the name FORTE was set up. Both - ries were united to FORTE/PSTV in 1996. In 2001 the conference changed the name to its current form. Recent conferences of this long series were held in Berlin (2003), Madrid(2004), Taipei(2005), Paris(2006), and Tallinn(2007). As in the previous year, FORTE 2008 was collocated with TESTCOM/ FATES 2008: the 20th IFIP International Conference on Testing of Com- nicating Systems (TESTCOM) and the 8th International Workshop on Formal Approaches to Testing of Software (FATES). The co-location of FORTE and TESTCOM/FATES fostered the collaboration between their communities. The commonspiritofboth conferenceswasunderpinnedby jointopening andclosing sessions, invited talks, as well as joint social events.

Most programmers' fear of user interface (UI) programming comes from their fear of doing UI design. They think that UI design is like graphic designthe mysterious process by which creative, latte-drinking, all-black-wearing people produce cool-looking, artistic pieces. Most programmers see themselves as analytic, logical thinkers insteadstrong at reasoning, weak on artistic judgment, and incapable of doing UI design.

In this brilliantly readable book, author Joel Spolsky proposes simple, logical rules that can be applied without any artistic talent to improve any user interface, from traditional GUI applications to websites to consumer electronics. Spolsky's primary axiom, the importance of bringing the program model in line with the user model, is both rational and simple.

In a fun and entertaining way, Spolky makesuser interfacedesign easy for programmers to grasp. After reading "User Interface Design for Programmers," you'll know how to design interfaces with the user in mind. You'll learn the important principles that underlie all good UI design, and you'll learn how to perform usability testing that works.

The primary objective of the conferences is to bring together researchersfromvariousareasandcommunities, includingtheoreticalandexp- imental computer science as well as many relevant application areas, to promote collaboration and the communication of new theoretical and practical results in SAT-related research and its industrial applications

On behalf of the Program Committee, it is our pleasure to present to you the proceedings of the 2nd GI SIG SIDAR Conference on Detection of Intrusions & Malware, and Vulnerability Assessment (DIMVA). DIMVA is organized by the Special Interest Group Security - Intrusion Detection and Response (SIDAR) of the German Informatics Society (GI) as an annual conference that brings together experts from throughout the world to discuss the state of the art in the areas of intrusion detection, detection of malware, and assessment of vulnerabilities. TheDIMVA2005ProgramCommitteereceived51submissionsfrom18co- tries. This represents an increase of approximately 25% compared with the n- ber of submissions last year. All submissions were carefully reviewed by at least three Program Committee members or external experts according to the cri- ria of scienti?c novelty, importance to the ?eld, and technical quality. The ?nal selection took place at a meeting held on March 18, 2005, in Zurich, Switz- land. Fourteen full papers were selected for presentation and publication in the conference proceedings. In addition, three papers were selected for presentation in the industry track of the conference. The program featured both theoretical and practical research results, which were grouped into six sessions. Philip Att?eld from the Northwest Security Institute gave the opening keynote speech. The slides presented by the authors are available on the DIMVA 2005 Web site at http: //www.dimva.org/dimva2005 We sincerely thank all those who submitted papers as well as the Program Committee members and the external reviewers for their valuable contributions.

The 2005 Australasian Conference on Information Security and Privacy was the tenth in the annual series that started in 1996.Over the yearsACISP has grown from a relativelysmallconferencewith a largeproportionof paperscoming from Australia into a truly international conference with an established reputation. ACISP 2005 was held at Queensland University of Technology in Brisbane, d- ing July 4-6, 2005. This year there were 185 paper submissions and from these 45 papers were accepted. Accepted papers came from 13 countries, with the largest proportions coming from Australia (12), China (8) and Japan (6). India and Korea both contributed 2 papers and one came from Singapore. There were also 11 papers from European countries and 3 from North America. We would like to extend our sincere thanks to all authors who submitted papers to ACISP 2005. The contributed papers were supplemented by four invited talks from e- nent researchers in information security. The father-and-son team of Prof. and Dr. Bob Blakley (Texas A&M University and IBM) gave a talk entitled "All Sail, No Anchor III," following up on a theme started at their ACISP 2000 - vited talk. Adrian McCullagh (Phillips Fox Lawyers and QUT) talked on the bene?t and perils of Internet banking. Ted Dunstone (Biometix) enlightened us on multimodal biometric systems. Yvo Desmedt (University College London) elucidated the growing gap between theory and practice in information security.

We welcome you to the proceedings of IWQoS 2005 held at the University of Passau, in the beautiful state of Bavaria, Germany. We hope that all attendees enjoyed their time in that ancient and historic city. Quality of Service(QoS) continues to be an important area of research. T- ditionally very focused on the area of networking, it has grown to include mobile applications, wireless environments, 3G and 4G cellular networks, user expe- ence, overlay networks, large-scale systemsand other important areas ofappli- tion. Six full-paper sessions that comprised selected papers of very high quality were devoted to the above mentioned, cutting-edge topics in this volume. We had a fascinating cross-disciplinary program and hope to have seeded conn- tions between di?erent disciplines and between industry and academia. In addition to the reviewed paper sessions, we were pleased to present two inspiring keynote speakers in this year's program: Randy Katz, Universityof California, Berkeley, USA, and Michael Stal, SiemensAG, Munich, Germany. One speaker being from academia and one from industry, re?ected well the balanced view of this workshop. Both keynotes extended the scope of QoS and addressed pressing issues, such as "spam," and leading trends, such as "service orientation," and their relevance to QoS.

ThisvolumecontainstheproceedingsoftheIFIPWG6. 1InternationalWorking Conference on Distributed Applications and Interoperable Systems V held in Athens, Greece, on June 15-17, 2005. The conference program presented the state of the art in research concerning distributed and interoperable systems. The emergence of 4th-generation c- munication systems, the evolution of Internet technologies, the convergence of telecom and datacom, wireless and ?xed communication systems and appli- tions pave the path for ubiquitous service and application provision. Innovative solutions are required for the development, implementation and operation of distributed applications in complex IT environments full of diversity and h- erogeneity. Today, the emerging wide spectrum of distributed systems - ranging from ambient intelligence to global computing scenarios - lacks systematic - plication development support. Following the evolution of the ?eld, DAIS 2005 focuses on models, technologies and platforms for interoperable, scalable and adaptable distributed applications within all kinds of computing environments. The papers presented at DAIS 2005 cover methodological aspects of building and architecting distributed and interoperable services, interoperability te- nologies, context- and location-based applications, con?gurability of commu- cation services, performance issues, data-integration issues, and Web services. In comparison to earlier events, the submissions showed increased interest towards methodological aspects and large-scale system interoperability. These proceedings contain 16 regular and 5 short papers, which were - lected in a careful, international reviewing process.
