摘要： A fault-tolerant messaging system comprises a primary broker, a first network, a back up broker, and a second network. The primary broker and the back up broker are coupled to the first network for communication with clients thus creating a messaging system. The primary broker and the back up broker are also coupled to the second network for replicating state from the primary broker and the back up broker, and also sending transaction events immediately to maintain synchronization. The brokers further comprise a replication module for communicating state between the primary broker and the back up broker, a recovery module for performing recovery on the back up broker upon failure of the primary broker, and a fault-tolerant connection module for establishing a fault-tolerant connection between the primary broker and the back up broker over the second network. The present invention also includes a number of novel methods for performing fault tolerance.

摘要： Techniques are disclosed for debugging heterogeneous applications in a distributed environment. In one embodiment, an architecture for debugging heterogeneous applications in a distributed environment is configured to enable both location transparency and dynamic exposure of service state. Regardless of where the physical application state resides, the architecture describes or otherwise provides a mechanism that allows seamless debugging and troubleshooting of distributed applications. The location of the state is transparent to the debugger and the application being debugged. In addition, the architecture enables an individual service to expose its state dynamically at run-time. It is possible for the service to expose its state in a self-describing fashion, allowing service state to be exposed in the architecture regardless of the service environment. The architecture allows for all the capabilities of debuggers running in non-distributed, homogeneous environments in a distributed heterogeneous environment.
摘要翻译：公开了用于在分布式环境中调试异构应用程序的技术。在一个实施例中，用于在分布式环境中调试异构应用的架构被配置为实现位置透明度和服务状态的动态曝光。不管物理应用程序状态在哪里，架构描述或提供了允许分布式应用程序的无缝调试和故障排除的机制。状态的位置对调试器和被调试的应用程序是透明的。此外，该架构使单个服务能够在运行时动态地暴露其状态。服务可以以自描述的方式公开其状态，允许服务状态暴露在架构中，而不管服务环境如何。该架构允许在分布式异构环境中在非分布式，同质环境中运行的调试器的所有功能。

摘要： A system and method for an extensible tracking system. A set of autonomous tags detect their location such as via GPS and broadcast their location to other nearby tags. Using separate communication technology, each tag can also communicate with an associated user device such as a smart phone. The user device(s) provide a user interface for queries into the system. The broadcasts among all tracking devices insures no reliance on a single tracking device, and associating tags with a respective set of user devices eliminates reliance on a central system for tracking to locations of all tags.
摘要翻译：一种用于可扩展跟踪系统的系统和方法。一组自主标签通过GPS检测其位置，并将其位置广播到其他附近的标签。使用单独的通信技术，每个标签还可以与诸如智能电话的相关联的用户设备进行通信。用户设备提供用于向系统查询的用户界面。所有跟踪设备之间的广播确保不依赖于单个跟踪设备，并且将标签与相应的一组用户设备相关联，消除了对中央系统的依赖，以跟踪所有标签的位置。

摘要： The disclosure includes a description of a method of handling messages received at a messaging system server. The method includes storing, in non-persistent storage, messages received from at least one client, removing delivered messages from the non-persistent storage, and saving messages stored in the non-persistent storage to persistent storage after a delay interval.
