ESUG to Feature Lecture on Discovering Smalltalk

Posted on in Categories Events, SmalltalkTags ,

Edinburgh, ScotlandAt the European Smalltalk User Group (ESUG) conference, which will be held in Edinburgh, Scotland on August 22-26, 2011, Stéphane Ducasse will be giving a lecture on Discovering Smalltalk.

Smalltalk is a pure and elegant object language, and this lecture will cover the fundamental aspects of Smalltalk: syntax, semantics and key aspects of the system, and in doing so, it will also revise the real semantics of self/super.

The lecture will show the power of polymorphism in action by simply learning from the system. Finally, he will go into the design aspect again based on the systems. As a bonus, he will start the lecture with a 15-minute presentation of Seaside, which is a powerful web framework for dynamic web applications.

This lecture may be followed by an additional lecture on more advanced object-oriented design: law of demeter, encapsulation, multiple interface of classes, and composition vs. inheritance.

The lecture takes place on Saturday, August 20 at 9h30 and ends at 16h00. For location information, visit
