Fundamental to any distributed system are communication patterns: point-to-point, request-reply, transactional queues, and publish-subscribe. Large distributed systems often employ two or more communication patterns. Using a single middleware that supports multiple communication patterns is a very cost-effective way of developing and maintaining large distributed systems. This talk will begin with an introduction of Data Distribution Service (DDS) – an OMG standard – that supports data-centric publish-subscribe communication for real-time distributed systems. DDS separates state management and distribution from application logic and supports discoverable data models. The talk will then describe how RTI Connext Messaging goes beyond vanilla DDS and implements various communication patterns including request-reply, command-response, and guaranteed delivery. You will also learn how these patterns can be combined to create interesting variations when the underlying substrate is as powerful as DDS. We’ll also discuss APIs for creating high-performance applications using the request-reply communication pattern.
C++11 feels like a new language. Compared to its previous standards, C++11 packs more language features and libraries designed to make C++ programs easier to understand and faster. As the community is building up experience with the new features, new stylistic ways of using them are emerging. These styles (a.k.a. idioms) give the new language its unique flavor. This talk will present emerging idioms of using rvalue references -- a marquee feature of C++11 as many renowned experts call it. You will see how C++11 opens new possibilities to design class interfaces. Finally, you will learn some advanced use-cases of rvalue references which will likely make you feel something amiss in this flagship feature of C++11. (This talk will assume some basic knowledge of rvalue references, move semantics, and perfect forwarding in C++11. If these concepts are new to you, I highly recommend Jon Kalb's session just before this one.)
