Dear Smalltalkers, We apologize for multiple reception of this announcement. The International Workshop on Smalltalk Technologies, is a European Smalltalk User Group (ESUG) Conference joint event, that focuses on research activities - namely academic creative work undertaken on smalltalk use, and more generally on object technologies. IWST was launched in 2009, in Brest, during the 17th ESUG Conference. The second edition took place in Barcelona, and the third edition was held in 2011 at the heart of historic Edinburgh. Next edition will be in Gent, Begium this summer (28th of august). ESUG gathers groups of professionals and hobbyists who share an interest in the Smalltalk programming languages and related technologies. The goal of the workshop is to create a forum around advances or experience in Smalltalk. IWST contributes to triggering discussions and exchanges of ideas. As always, we make a point to have a very constructive paper review process that aims to provide in-depth comments and suggestions to all of them (no one-liners!) This makes it ideal to disseminate new research directions, and is a good venue for early stage PhD students to receive feedback on their work. In addition, we intent to invite best papers to a journal special issue as we did last year. Looking forward to your submissions, and to meeting you in Gent! Best regards, Loïc Lagadec& Alain Plantec Co-chairs of IWST International Workshop on Smalltalk Technologies 2012 August 28th, 2012 Gent, Belgium. ESUG 2012 Smalltalk joint event Important dates Submission deadline: June 15, 2012 Notification deadline: July 15, 2012 All accepted papers will be published in ACM DL, and the authors of the best papers will be invited to submit an extended version to a journal special issue (To Be Confirmed). Goals and scopes The goals of the workshop is to create a forum around advances or experience in Smalltalk and to trigger discussions and exchanges of ideas. Participants are invited to submit research articles. We will not enforce any length restriction. However we expect papers of two kinds: Short position papers describing emerging ideas. Long research papers with deeper description of experiments and of research results. Topics We welcome contributions on all aspects, theoretical as well as practical, of Smalltalk related topics such as: Aspect-oriented programming, Design patterns, Experience reports, Frameworks, Implementation, new dialects or languages implemented in Smalltalk, Interaction with other languages, Meta-programming and Meta-modeling, Tools Links home page:http://www.esug.org/wiki/pier/Conferences/2012/International-Workshop---IWST... submission:http://www.easychair.org/conferences/?conf=iwst2012 Publication Both submissions and final papers must be prepared using the ACM SIGPLAN 10 point format. Templates for Word and LaTeX are available at http://www.acm.org/sigs/sigplan/authorInformation.htm. This site also contains links to useful informations on how to write effective submissions.
