Sie wollen oder müssen Architektur dokumentieren und möchten dafür grafische Darstellungen verwenden? Sie wünschen sich verständliche Diagramme, die auch zukünftig noch leicht änderbar sind? Sie möchten, dass Ihre Diagramme für unterschiedliche Zielgruppen nützlich sind? Und wenn Sie ganz ehrlich sind, wollen Sie dieses Doku-Zeugs in möglichst kurzer Zeit erledigen, damit Sie sich wieder anderen Dingen zuwenden können.
The OPC Unified Architecture (UA), released in 2008, is a platform independent service-oriented architecture that integrates all the functionality of the individual OPC Classic specifications into one extensible framework.
This multi-layered approach accomplishes the original design specification goals of:
- Functional equivalence: all COM OPC Classic specifications are mapped to UA
- Platform independence: from an embedded micro-controller to cloud-based infrastructure
- Secure: encryption, authentication, and auditing
- Extensible: ability to add new features without affecting existing applications
- Comprehensive information modeling: for defining complex information
Architects look at thousands of buildings during their training, and study critiques of those buildings written by masters. In contrast, most software developers only ever get to know a handful of large programs well—usually programs they wrote themselves—and never study the great programs of history. As a result, they repeat one another's mistakes rather than building on one another's successes.
Our goal is to change that. In these two books, the authors of four dozen open source applications explain how their software is structured, and why. What are each program's major components? How do they interact? And what did their builders learn during their development? In answering these questions, the contributors to these books provide unique insights into how they think.
If you are a junior developer, and want to learn how your more experienced colleagues think, these books are the place to start. If you are an intermediate or senior developer, and want to see how your peers have solved hard design problems, these books can help you too.

NATS Server is a simple, high performance open source messaging system for cloud native applications, IoT messaging, and microservices architectures.
Welcome. The purpose of this site is to share the lore of designing parallel computers and integrated systems-on-chips using FPGAs (field-programmable gate arrays). It is the continuation of the long fallow FPGA CPU News.

RISC-V (pronounced "risk-five") is a new instruction set architecture (ISA) that was originally designed to support computer architecture research and education and is now set to become a standard open architecture for industry implementations under the governance of the RISC-V Foundation. The RISC-V ISA was originally developed in the Computer Science Division of the EECS Department at the University of California, Berkeley.
An important ingredient in the Technology of Cyberspace is the ability to let any user communicate with any other user or service. How do we wire 5 billion people on the planet? That's an engineering problem - to design a network capable of handling such numbers over such a wide geographic area. We are going to talk about the engineering aspects of such network design for next two lectures.
The OpenPOWER Foundation is an open technical community based on the POWER architecture, enabling collaborative development and opportunity for member differentiation and industry growth.
Dark Internet Mail Environment (DIME) Specification
To bring the world our unique end-to-end encrypted protocol and architecture that is the 'next-generation' of private and secure email. As founding partners of The Dark Mail Technical Alliance, both Silent Circle and Lavabit will work to bring other members into the alliance, assist them in implementing the new protocol and jointly work to proliferate the world's first end-to-end encrypted 'Email 3.0' throughout the world's email providers. Our goal is to open source the protocol and architecture and help others implement this new technology to address privacy concerns against surveillance and back door threats of any kind.
