Empowering Biosemiotics, Charles Lassiter Jan 2022

Empowering Biosemiotics, Charles Lassiter

Philosophy Faculty Scholarship

One way to understand the basic semiotic relation is that a sign-vehicle signifies an object to an interpretant. Biosemioticians sometimes talk about this relationship in terms of “codes”. When thinking about this relationship in the context of language, a natural move is to conceptualize semiotic relationships among speakers, meanings, and utterances as codes: speakers encode messages in sentences, which are then decoded by an interpreter. This view of communication is inconsistent with core tenets of a distributed approach to language, which holds that language is an embodied and encultured activity taking place across multiple timescales. I argue that a neo-Aristotelian …

Understanding The Patterns Of Microservice Intercommunication From A Developer Perspective, Anas Nadeem Jan 2022

Understanding The Patterns Of Microservice Intercommunication From A Developer Perspective, Anas Nadeem

Computer Science

Microservices Architecture is the modern paradigm for designing software. Based on the divide-and-conquer strategy, microservices architecture organizes the application by furnishing it with a fine-level granularity. Each microservice has a well-defined responsibility and multiple microservices communicate with each other toward a common goal. A momentous decision in designing microservices applications is the choice between orchestration or choreography-based modes as the underlying intercommunication pattern. Choreography entails that microservices work autonomously while orchestration entails that a central coordinator directs the interaction between services. We arbitrate this decision from a developer’s perspective by empirically evaluating the properties of a benchmark system mapped into …
