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 spoken at the last few ACCU conferences and found it a rewarding experience, despite (or because of) the audience participation.

Russel Winder

Russel was originally a theoretical particle physicist but decided in 1980 that being a UNIX systems programmer was more fun. Which it was. 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, philosophy of information systems, 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 income flooded in and so it had to fold. Since then, Russel has been a consultant, analyst, and trainer -- programming in Python, Java SE, Java ME, and Groovy; creating builds using SCons, Waf, Gradle, Gant, Maven, and Ant; and controlling your versions with Bazaar, Mercurial, Git, and Subversion -- and and author -- "Developing Java Software" third edition, and "Python for Rookies". The Multicore Processors that has crept up over the last five years means that parallelism has finally arrived (after 30+ years of being the next coming technology), so Russel has been able to return to being interested in all things concurrent and parallel in software systems. Russel is centrally involved with the development of the Groovy programming language and the GPars framework for creating parallel software, is centrally involved in Python-CSP and PyCSP which is bringing CSP to the world of Python, is author of the Gant Ant task scripting framework, and contributes to the Gradle and SCons build frameworks.

Sander Hoogendoorn
