摘要： In one example, a computing device generates a new password for accessing a user account and/or computing system and inspires a change of an existing password for the user account and/or computing system to the new password. Thereafter, the computing device detects occurrence of a condition to trigger another change of the password for the user account and/or computing system and, responsively, inspires another change of the password for the user account and/or computing system.

摘要： A computer system includes physical registers holding data for compiled programs and a portion of the physical registers form a register stack which wraps around when full. An N-bit current wraparound count state tracks physical register remapping events which cause the register stack to wraparound or unwrap. An advanced load address table (ALAT) has entries corresponding to load instructions, each entry has at least one memory range field defining a range of memory locations accessed by a corresponding load instruction, a physical register number field corresponding to a physical register accessed in the corresponding load instruction, and an N-bit register wraparound field which corresponds to the N-bit current wraparound count state for the corresponding load instruction. A check instruction accesses the ALAT to determine whether a store instruction and an advanced load instruction, which is scheduled before the store instruction, potentially accessed a common memory location. After the execution of the store instruction, an absence of an entry corresponding to the load instruction in the ALAT indicates that a common memory location may have been accessed by the store and load instructions.

摘要： A software system with self-describing attribute vocabularies that enhance the capability of service providers to advertise their resources and that facilitate the addition of new types of attributes and resources to the system. Each self-describing attribute vocabulary is characterized by a corresponding set of attribute properties and a corresponding set of:matching rules that are adapted to the corresponding attribute properties. The software system includes a matching engine that enables a service provider of a resource to describe the resource to the software system in terms of any one or more of the self-describing attribute vocabularies.

摘要： A new application sharing technology that enables sharing of many single-user non-modified applications between two or more workstations. It provides concurrent sharing of existing multiple applications with no change in a distributed environment. It permits real-time sharing of distributed applications based on a fundamental window hierarchical mapping and user interactions. Control is centralized but the data and program are replicated. It is event driven with agent assistance. The new event capturing capability is automatically triggered by user interactions on entering/leaving the shared window. The event capturing capability starts when the user moves the pointer into the shared windows. The event capturing ends when the user moves the pointer out of the shared windows. The new multicasting scope is defined in a shared window hierarchy data array. This global data array is dynamically created at run time on an as-needed basis. Because this mechanism only processes user input events such as mouse, keyboard or cursor movement (commands), no output graphic data transmission across the network is required. Therefore, this approach is extremely light-weight and provides secure transmission without requiring intensive encryption. Because it is not using pseudo server interception, this approach can support DHA 3-D rendering. Also, the agent can dynamically mediate resources and normalize environment differences. This permits real-time sharing of 3-D, graphic and DHA (direct hardware access) applications. DHA permits the application to bypass the windowing server to render graphics on display. Moreover, because it is extremely light-weight, high network bandwidth is not required.
摘要翻译：一种新的应用程序共享技术，可在两个或多个工作站之间共享许多单用户未修改的应用程序。它提供了现有多个应用程序的并发共享，而且在分布式环境中没有变化。它允许基于基本窗口分层映射和用户交互的实时共享分布式应用程序。控制是集中的，但数据和程序被复制。事件由代理协助驱动。在进入/离开共享窗口时，新的事件捕获功能将由用户交互自动触发。当用户将指针移动到共享窗口时，将启动事件捕获功能。当用户将指针从共享窗口中移出时，事件捕获将结束。新的组播范围在共享窗口层次结构数据数组中定义。该全局数据阵列在运行时根据需要动态创建。因为这种机制只处理用户输入事件，如鼠标，键盘或光标移动（命令），则不需要通过网络输出图形数据传输。因此，这种方法非常轻便，并且提供安全的传输，而不需要密集的加密。因为没有使用伪服务器拦截，这种方法可以支持DHA 3-D渲染。此外，代理可以动态调解资源并规范环境差异。这允许实时共享3-D，图形和DHA（直接硬件访问）应用程序。 DHA允许应用程序绕过窗口服务器以显示显示的图形。而且，由于重量轻，所以不需要高的网络带宽。
