Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

Connected Data Objects (CDO) is a free implementation of a Distributed Shared Model on top of the Eclipse Modeling Framework (EMF).
With CDO, programmers can easily enhance existing EMF models in such a way that they can be stored and subsequently maintained in a central model repository. While object relational mapping against a JDBC data source on the server side is the shipped default, CDO provides for pluggable storage adapters that allow you to develop and use different mappers (like Hibernate- or OODB-based). On the client side, CDO provides a default integration with EMF, the Eclipse Modeling Framework, although other model integrations on top of the CDO protocol are imaginable as well.

The doubly connected edge list (DCEL), also known as half-edge data structure, is a data structure to represent an embedding of a planar graph in the plane, and polytopes in 3D. This data structure provides efficient manipulation of the topological information associated with the objects in question (vertices, edges, faces). It is used in many algorithms of computational geometry to handle polygonal subdivisions of the plane, commonly called planar straight-line graphs (PSLG). For example, a Voronoi diagram is commonly represented by a DCEL inside a bounding box. This data structure was originally suggested by Muller and Preparata for representations of 3D convex polyhedra. Simplified versions of the data structure, as described here, only consider connected graphs, but the DCEL structure may be extended to handle disconnected graphs as well by introducing dummy edges between disconnected components.
A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or supervisory control and data acquisition (SCADA) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects. Other terms that may be used for RTU are remote telemetry unit and remote telecontrol unit.
Internet of things (IoT) describes physical objects that are embedded with sensors, processing ability, software, and other technologies that connect and exchange data with other devices and systems over the Internet or other communication networks. The field of IoT encompasses electronics, communication, and computer science engineering. "Internet of things" has been considered a misnomer because most devices do not need to be connected to the public Internet; they only need to be connected to a network and be individually addressable. The field has evolved due to the convergence of multiple technologies, including ubiquitous computing, sensors, embedded systems, and machine learning. Traditional fields of embedded systems, wireless sensor networks, control systems, and automation independently and collectively enable the Internet of things. While in the consumer market, IoT technology is most commonly known as smart home products—including devices and appliances like thermostats and smart speakers—the technology's largest applications are in the business and industrial sectors. Commercial asset tracking and fleet management represent the largest single application of IoT, accounting for 22% of the total market, driven by the need to monitor mobile assets like vehicles and shipping containers. The largest asset tracking sub-segments in transport & logistics are trailer and intermodal container tracking, reaching 5.8 million and 5.3 million active devices globally at the end of 2024 respectively. Other major applications include industrial monitoring, smart metering in utilities, and connected healthcare. There are a number of concerns about the risks in the growth of IoT technologies and products, especially in the areas of privacy and security, and consequently there have been industry and government moves to address these concerns adequately and minimize safety risks, including the development and implementation of international and local standards, guidelines, and regulatory frameworks. Due to their interconnected nature, IoT devices are vulnerable to security breaches and privacy concerns. At the same time, the way these devices communicate wirelessly creates regulatory ambiguities, complicating jurisdictional boundaries of the data transfer.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
