ESUG

ESUG

The European Smalltalk User Group (ESUG) is a volunteer-led association that supports the Smalltalk community across Europe and beyond. Founded in the early 1990s, ESUG organizes conferences, fosters projects, and connects practitioners, researchers, and educators from institutions such as University of Cambridge, ETH Zurich, INRIA, Imperial College London, and companies including GemStone Systems, Cincom Systems, Cincom Smalltalk, Pharo Consortium. ESUG facilitates exchanges among developers linked to implementations and environments such as Pharo, Squeak, GNU Smalltalk, VisualWorks, Dolphin Smalltalk, ObjectWorks, VA Smalltalk, Smalltalk/X, ST/X.

History

ESUG emerged during a period of renewed interest in dynamic languages, following milestones like the widespread use of Smalltalk-80 at organizations such as Xerox PARC and academic work at MIT. Early contributors included participants from Apple Computer research circles, alumni of PARC, and faculty associated with University of Kent and University of Oxford. The group’s timeline intersects with software projects and events such as Squeakland, the release cycles of Pharo 1.0, initiatives from Esug conference organizers and collaborations with corporate adopters including Hewlett-Packard and IBM. ESUG’s early conferences provided forums where implementers from Cincom and open-source communities like Squeak Foundation and Pharo Association discussed language design decisions, reflections on the Smalltalk-80 Blue Book, and lessons from large deployments at institutions like British Telecom.

Organization and Governance

ESUG is governed by a volunteer board that resembles structures used by associations such as IEEE technical committees and non-profits like ACM SIGPLAN. The board coordinates membership, conference programming, sponsorship, and project funding in collaboration with national user groups analogous to German Smalltalk User Group or local chapters in cities like Paris, Berlin, Amsterdam, London, Zurich. Officers have included academics and industry representatives affiliated with University of Twente, Technical University of Munich, Delft University of Technology, University of Warwick, and companies such as Cincom Systems and GemTalk Systems. Decision-making follows bylaws modeled on standards used by organizations like Free Software Foundation and Apache Software Foundation, with working groups for code of conduct, finance, and outreach.

Annual Conference and Events

ESUG is best known for its annual conference that draws presenters from institutions such as University of Cambridge Computer Laboratory, Oxford University Computing Laboratory, ETH Zurich, and companies like Google, Microsoft Research, Facebook, SAP, and Twitter (service). The conference features tracks on language implementation, virtual machines, development tools, and pedagogy, with sessions referencing seminal works by researchers associated with Adele Goldberg, Alan Kay, Dan Ingalls, Ted Kaehler, and Yukihiro Matsumoto-adjacent discourse on dynamic systems. Past venues have included cities like Brussels, Prague, Paris, Edinburgh, Bologna, and Amsterdam. ESUG events also host Birds-of-a-Feather gatherings inspired by formats used at PyCon, Strangeloop, OSCon, and include workshops led by teams from Pharo Consortium, Squeakland Foundation, GemStone Systems, and contributors associated with Seaside web framework and Bloc libraries.

Activities and Projects

ESUG supports collaborative projects spanning implementation, tooling, and education. Notable activities include sprints and hackathons that have advanced Pharo releases, improved debugging tools influenced by designs from Smalltalk-80 implementers, and produced integrations with platforms such as JVM and CLR via bridges inspired by work at Oracle and Microsoft Research. ESUG-backed initiatives have contributed to documentation efforts reminiscent of the Smalltalk-80 Blue Book and modern tutorials similar to materials from MIT OpenCourseWare and Coursera courses on programming languages. The group has coordinated with foundations like the Squeak Foundation and the Pharo Association to fundmentorship programs, community-driven testing harnesses, and packaging efforts comparable to ecosystems maintained by Debian and Homebrew. ESUG also curates an archive of conference proceedings, recorded talks, and code repositories that reference implementations from Squeak, Pharo, Cuis Smalltalk, GNU Smalltalk, and commercial systems released by Cincom.

Impact on the Smalltalk Community

ESUG has played a central role in sustaining cross-pollination between academic research and industrial practice in the Smalltalk ecosystem. By convening contributors from research centers such as University of Illinois Urbana-Champaign, Rutgers University, Carnegie Mellon University, and industry practitioners from GemStone Systems, Cincom Systems, and startups incubated at Cambridge Innovation Center, ESUG has supported evolution in areas like virtual machine optimization, garbage collection strategies discussed in forums influenced by work at SUN Microsystems and Bell Labs, and modern tooling for live programming influenced by projects at Microsoft Research and Google Research. ESUG’s conferences and working groups have helped maintain interoperability among implementations, encouraged adoption of open-source licensing models used by Apache Software Foundation and MIT License projects, and inspired educational adoption at institutions including University of Cambridge, Imperial College London, Delft University of Technology, and ETH Zurich. The network fostered by ESUG continues to influence language design debates alongside communities for languages such as Ruby, Python, Smalltalk-80, Self (programming language), and Lisp.
