Conference 2010

Alan Griffiths

Alan Griffiths is a regular at the ACCU conference and has been developing software through many fashions in development processes, technologies, and programming languages. During that time he's delivered working software and development processes to a range of organizations, written for a number of magazines, spoken at a number of conferences and made many friends. Firmly convinced that common sense is a rare and marketable commodity he's currently working as an independent through his company, Octopull Limited http://www.octopull.co.uk/.

Albrecht Fritzsche

Albrecht Fritzsche is a Senior Software Developer at mental images, involved from the very start in a project of developing a 3D web services software platform that is highly scalable to thousands of servers.

His personal software related interests are in the domain of lock-free programming incl. Transactional Memory.

Andrei Alexandrescu

Andrei Alexandrescu coined the colloquial term "modern C++", used today to describe a collection of important C++ styles and idioms. His eponymous book on the topic, Modern C++ Design: Generic Programming and Design Patterns Applied (Addison-Wesley, 2001), revolutionized C++ programming and produced a lasting influence not only on subsequent work on C++, but also on other languages and systems. With Herb Sutter, Andrei is also the coauthor of C++ Coding Standards: 101 Rules, Guidelines, and Best Practices (Addison-Wesley, 2004). Through Andreis varied work on libraries and applications, as well as his research in machine learning and natural language processing, he has garnered a solid reputation in both industrial and academic circles. Since 2006, he has been second-in-command to Walter Bright, the D programming language inventor and initial implementer. Andrei has been the key designer of many important features of D and has authored a large part of D's standard library, positioning him to write an authoritative book on the new language, appropriately entitled, The D Programming Language. Andrei holds a PhD in Computer Science from the University of Washington and a BS in Electrical Engineering from University "Politehnica" Bucharest. He works as a Research Scientist for Facebook.

I have been a member of ACCU since 1999; I currently run the Code Critique section of CVu and also write the occasional article. I've joined several projects over the years where configuring the software to run was so hard it was a couple of weeks before I had a functioning development environment and have also spent more time than I'd like dealing with problems caused by misconfiguration.

Russel Winder

Russel was originally a theoretical particle physicist but decided in 1980 that being a UNIX systems programmer was more fun. However, academia continued to call and he moved to UCL to lecture in programming, software engineering and human--computer interaction, and do research on parallel programming languages and socio-technical aspects of software development. After 13 years at UCL, Russel moved to KCL to be Professor of Computing Science. Having revamped the teaching programme, continued the research on parallel programming languages, and started research programmes in health informatics, it was time for new challenges so he left KCL to become CTO of OneEighty Software Ltd, a company using novel virtual machine approaches to embedded systems. Unfortunately, the money ran out for this start-up before the orders flooded in and so it had to fold. Since then, Russel has been a consultant, analyst, trainer (Java SE, Java ME, Groovy and Python) and author ("Developing Java Software" third edition, and "Python for Rookies"). The recent rise of multicore processors means that parallelism has finally arrived (after 30 years of being the coming technology), so Russel with two colleagues started a new consultancy practice (Concertant LLP) undertaking consultancy, analysis and management work in all areas of parallelism and concurrency. Russel is centrally involved with the development of the Groovy programming language and the GParallelizer framework, is author of the Gant Ant task scripting framework, and contributes to the Gradle and SCons build frameworks.
