JetLinks Community is an open-source enterprise IoT platform built with Java, Spring Boot, WebFlux, Netty, Vert.x, Reactor, and related reactive technologies. It is designed to help teams quickly build IoT business systems without starting from a blank backend. The platform supports unified device modeling, unified device access, and centralized management across different device types, vendors, and communication protocols. It can connect devices through TCP, UDP, MQTT, HTTP, TLS, DTLS, and other protocol patterns while hiding much of the complexity of network programming. JetLinks also includes real-time data processing, device alerts, message notifications, data forwarding, geographic features, visualization, and a configurable rule engine. ...

OpenDDS is an open source implementation of the Object Management Group (OMG) Data Distribution Service (DDS), providing a publish/subscribe middleware solution for real-time distributed systems. OpenDDS includes development and run-time tools. Full product information, source code, documentation, build instructions, and license information are available from http://www.opendds.org. Commercial consulting, support, and training for OpenDDS are available. OpenDDS is in production use...

...It includes provision for dumping excess heat to the distribution system, as well as provision for heat recovery during a cool-down cycle. The design is based on the 1-wire family of sensors and data I/O components. The software package is written in C++ and utilizes the owcapi and owlib facilities of the open-source owfs package for all 1-wire transactions. The software architecture is based on the QP hierarchical state machine framework developed by Quantum Leaps, and utilizes their QM modeling tool for state machine template generation. ...

...It walks readers through the architecture, concepts, and engineering stack behind IoT systems instead of only listing isolated tools. The guide covers topics such as IoT market context, device models, ThingsBoard source-code learning, MQTT broker setup, CoAP services, message peak shaving, data modeling, and database selection. It is intended for developers who want to learn how real IoT platforms organize devices, messages, protocols, and backend services. The repository is especially useful as a structured study path for readers preparing to build or customize an IoT platform. It functions more as a technical tutorial and roadmap than as a single installable software package.

Zenoss provides software-defined IT operations for the world’s largest organizations. We deliver the ultimate level of IT service health with simplicity by providing the most granular and intelligent IT service modeling possible, at any scale, and sharing these unique insights with other IT operations management (ITOM) tools to make them more efficient. Zenoss Community Edition is not a “demo” or trial version of Zenoss Enterprise or Zenoss Cloud! Before You install Zenoss Community...

Albedo is an open-source recommender system aimed at helping developers discover GitHub repositories by learning from activity signals. It treats repositories and developers as a graph of interactions and applies large-scale matrix factorization to model affinities, with Apache Spark providing the distributed data processing. The project focuses on implicit feedback—stars, watches, and other engagement metrics—so it can build useful recommendations without explicit ratings. A reproducible...

3D-Console is a system that maintains and renders a general purpose user interface for multiple applications in a shared three dimensional virtual space. The applications are arbitrary operating system processes, as we know them.

xcruiser aims to provide 3D VR-like interface to UN*X filesystem. It displays directories as galaxies, files as planets (of various properties depending on its attributes) and symlinks as wormholes. You can fly through cyberspace created from these.

A device server inteded for (but not limited to) use with 3D input devices (like dynasight, Polhemus FASTRAK, motionstar and the magellan spacemouse). Devices can be configured via a remote TCP connection. Device data is sent to registered clients via
