The 14th foreign Smalltalk convention happened within the ?rst week of September 2006 in Prague, Czech Republic. This quantity comprises the pe- reviewed technical papers that have been awarded through the educational tune of the convention. The foreign Smalltalk convention evolvedout of the once a year assembly of the eu Smalltalk person workforce (ESUG). This assembly frequently lasts a few week and permits Smalltalk specialists to debate Smalltalk recommendations and envir- ments. The assembly draws a various viewers along with Smalltalkers from in addition to from academia. due to the perpetual e?ort of individuals like St´ ephane Ducasse, Noury Bouraqadi, Serge Stinckwich and Roel Wuyts, through the years the ESUG assembly was once supplied with a separate educational study song within which researchers may perhaps current educational effects approximately Smalltalk and its improvement instruments. regrettably, no formal booklet discussion board used to be - sociated with this music, which made it much less appealing for authors to publish a paper. beginning with this version of the convention, we are hoping this may swap. An contract used to be reached with Springer to submit a post-conference lawsuits of this 14th variation. i believe our group owes an important thanks to St´ ephane for this! optimistically subsequent yr this contract can evolve right into a fifteenth version of the convention with officially introduced lawsuits. this may definitely encourage extra Smalltalk researchers to publish a paper! The convention approved simply over half the submissions.

Online Worlds: Convergence of the Real and the Virtual (Human-Computer Interaction Series)

Virtual worlds are chronic on-line computer-generated environments the place humans can have interaction, no matter if for paintings or play, in a fashion equivalent to the true global. the most well-liked present instance is global of Warcraft, a hugely multiplayer game with 11 million subscribers. besides the fact that, different digital worlds, particularly moment lifestyles, aren't video games in any respect yet internet-based collaboration contexts within which humans can create digital items, simulated structure, and dealing groups.

This booklet brings jointly a world staff of hugely finished authors to ascertain the phenomena of digital worlds, utilizing a number theories and methodologies to find the rules which are making digital worlds more and more well known, and that are constructing them as an immense region of human-centred computing.

Sample text

However, both fail to provide cues about how application objects should be structured to seamlessly interact with the sensing layers. Our approach proposes a clear separation of concerns between those object features that are context-free, those that involve context-sensitive information (like location and time) and the context-aware services. By placing these aspects in separated layers, we obtain modular applications in which modifications in one layer barely impact in others. To achieve this modular architecture we based on the work of Beck and Johnson [2] in the sense that the sum of our microarchitectural decisions (such as using dependencies or decorators) also generate a strong, evolvable architecture.

Similarly, in our approach, context is not treated as data on which rules or functions act, but it is the result of the interaction between objects, each one modeling a given context concern. This idea is based on the concept of a context aspect, that represents the behavior that is contextually relevant to model in a specific situation. From an architectural point of view, our work can be rooted to the Context Toolkit [4] which is one of the first approaches in which sensing, interpretation and use of context information is clearly decoupled.

Remote Objects and Proxies. A remote proxy [7] is a local representative for an object (its subject ) that resides in a different address space. When a message is sent to the proxy, it automatically forwards it to its subject and waits for its 38 A. Fortier et al. response. Thus, from the sender point of view, there is no difference between working with local or remote objects2 . e. an IP address + a port number) and an object identifier (also known as oid ). When an instance of RemoteObject receives a message, it forwards the request to its subject by means of the #doesNotUnderstand: mechanism; for this purpose the proxy leans on the broker’s services, which is responsible for deliver the message through the network.
