July CoreDX DDS Connection 2024 Welcome to the Twin Oaks Computing, Inc Newsletter! Our monthly newsletter brings you news and information about Twin Oaks Computing and our CoreDX DDS middleware. Be sure to "like", "follow" and "friend" us on our Social Networking sites for fun facts, free giveaways, and stories about Communications Middleware, Technology, and Twin Oaks Computing. Exploring DDS X-Types - Webinar on Demand Join Nina Tucker, VP of Engineering at Twin Oaks Computing, as she explores DDS X-Types. One of the fundamental concepts in the DDS technology is the use of data type information to make data exchange robust, efficient, and feature-rich. The X-Types specification provides a rich toolset for defining data types for use in DDS Systems. This includes how data types are defined, how they may evolve, how they are exchanged between DDS participants at run-time, and rules for data type assignability. In this episode of the DDS Foundation's 20th Anniversary webinar series, we will explore the Extensible and Dynamic Types for DDS (or "X-Types") specification and learn how this very important component of the DDS standards impacts the design, function, and interoperability of DDS systems. You can view the webinar here Contact Twin Oaks Computing to learn more about X-Types concepts with CoreDX DDS. CoreDX DDS Tips & Tricks Welcome to this month's edition of CoreDX DDS Tips & Tricks, where our engineers provide quick bits of information to help our customers. What is safe to do inside a listener method (and what should be avoided)? CoreDX DDS pub/sub listeners (that is, listeners for the DomainParticipant, Publisher, Subscriber, DataWriter, DataReader) are thread and reentrant safe. The only "no no" is deleting the DDS Entity you are operating with (in the case of on_data_available, don't delete the DataReader, or its associated Topic). CoreDX DDS RPC listeners have an additional constraint: do not call an RPC service inside an RPC client. RPC applications that contain both services and clients should consider creating two DomainParticipants. One DomainParticipant will be for services and the other will be for clients. CoreDX DDS Tips & Tricks are intended to be useful for engineers using CoreDX DDS. If you have any questions, please contact us.
