Abstract: Techniques disclose managing cloud computing resources provisioned to processing elements of a distributed application (e.g., for a streams processing environment). A cloud manager determines changes in availability of cloud resources. The cloud manager notifies a runtime manager of a distributed application of the change in availability. The runtime manager in turn requests that the cloud manager adjust the provisions based on the notification. The cloud manager provisions the cloud resources based on the request.

Abstract: A computer may detect, during a first time period, a message written to a composer. The computer may analyze a first set of usage patterns of a composer's personal device that correspond to the first time period. The computer may also analyze a second set of usage patterns of the composer's personal device that correspond to a second time period. The computer may identify usage habits of the composer based on analyzing the second set of usage patterns. The computer may also identify a difference between the first set of usage patterns and the usage habits of the composer. The computer may determine that the composer was in an impaired state during the first time period based on the difference. The computer may then notify the composer of the difference.

Abstract: A method for regulating output from stream operators performing a windowing operation may include receiving stream of tuples to be processed by a plurality of processing elements, each processing element having one or more stream operators. The method may also include receiving a first stream of tuples at a first stream operator, the first stream operator being configured to generate a stream of accumulated tuples according to a set of windowing conditions. The method may then include processing the stream of accumulated tuples in response to a window trigger, where the processing generates a quantity of output. At least one processor may then monitor the quantity of output to determine whether the quantity of output exceeds a data output threshold. The processing may then be adjusted, in response to determining that the quantity of output exceeds the data output threshold, to reduce the output to approach the data output threshold.

Abstract: An electronic device includes a pressure-sensitive touch screen display that can dynamically monitor a user's interaction with the device, and adjust the pressure thresholds of different areas of the touch screen display based on the user's monitored interactions. The orientation of the device is determined, the touch screen display is divided into sections, and the device monitors the pressure the user applies in the different sections of the screen. A pressure map is then created that includes pressure detection thresholds specific to the orientation and user for one or more regions of the screen. The device may include different pressure maps for different orientations of the device. When the user interacts with the touch screen, the device determines what the user intended based on the orientation of the device and the thresholds in the pressure map for that orientation for the region of the screen touched by the user.

Abstract: A web server includes a client pressure profile sharing and generation mechanism that detects when a user accesses the web server with a first device that does not have a client pressure profile, and automatically generates a client pressure profile for the first device from a client pressure profile for a second device used by the user. Adjustments may be automatically made to the client pressure profile for the first device based on differences in orientation and based on differences in screen size. Changes by the user to the client pressure profile for the first device can be automatically propagated to client pressure profiles for other devices used by the user.

Abstract: An approach is provided in which an information handling system retrieves a snapshot of a first service in response to determining that the first service has failed. The snapshot was captured at a point in time prior to the failure of the first service. The information handling system retrieves a log corresponding to the first service that includes a log entry of a message sent between the first service and a second service that was sent subsequent to the capturing of the snapshot. In turn, the information handling system restores the first service using the snapshot and the message.

Abstract: A mobile device detects its location and other devices in proximity to the mobile device. When the device is in an untrusted location, or is in physical proximity to an untrusted device, the mobile device ensures existing security and authentication mechanisms are in place, and may additionally require enhanced security measures on the device. In addition, the device may modify its functionality based on the mobile device being in an untrusted location or in physical proximity to an untrusted device.

Abstract: A stream computing application may be configured to manage the flow of tuples through a section of an operator graph. A window may be generated over one or more stream operators. The window may include breakpoint thresholds that set the maximum flow of tuples within the window. The stream operators within the window may be monitored to determine the flow of tuples occurring within the window using tuple flow counts. The tuple flow counts may be compared to the breakpoint thresholds to determine whether a breakpoint condition has occurred. If a breakpoint condition has occurred, a tuple flow change may be implemented to reduce the flow of tuples within the window.

Abstract: A method for debugging and executable is disclosed herein. The method begins by receiving one or more breakpoints defining one or more attributes of a call stack in the executable. The processor receives the executable in a debug environment. The processor executes the executable in the debug environment. The processor halts execution of the executable upon detection of a breakpoint contained in the executable.

Abstract: A method for debugging an executable is disclosed herein. The method begins by receiving one or more breakpoints related to a call stack in the executable. The processor receives an executable in a debug environment. The processor executes an executable until one or more breakpoints are hit. Upon detecting a breakpoint, the processor temporarily halts executing by transferring control to an analysis tool to gather information related to execution of the executable up to the breakpoint. The analysis tool gathers one or more predefined outliers. The processor receives control back from the analysis tool to continue execution in response to the analysis tool collecting relevant information in the executable.

Abstract: A method for processing distributed breakpoints when debugging a distributed application includes establishing a breakpoint in source code of a distributed computer program and executing the distributed computer program. Thereafter, an encountering of the breakpoint is detected in one of the processes, and execution of the one of the processes halted. However, halting execution of any other of the processes is delayed for a delay period during which a list both is generated of others of the processes in which the breakpoint is encountered and also is sorted in accordance with prioritization criteria. Finally, the sorted list is presented after the lapse of the delay period, individual ones of the processes selected in the list, and execution of the selected individual ones of the processes in the sorted list halted while halting of execution of non-selected ones of the processes in the sorted list is bypassed.

Abstract: Determining a time for on-demand snapshotting of a virtual machine in a node prior to a failure point in a system comprising a plurality of nodes. Failure data is collected from a set of failed nodes of the plurality of nodes in a system.

Abstract: An approach is disclosed that receives power related data from one or more power systems. The approach then determines, based on an analysis of the power related data, an anticipated power outage, with the power outage includes a power outage time estimate. The approach further identifies jobs to be migrated from a primary data center to a remote data center. The identification of the jobs to be migrated is based, at least in part, on the power outage time estimate.

Abstract: A web server includes a pressure-sensitive page rendering mechanism that renders web pages that have one or more selectable inputs according to a client pressure profile corresponding to the requesting user. When the web server receives the request, the web server may dynamically generate and render a web page that satisfies the client pressure profile by placing one or more selectable inputs on the web page in one or more preferred regions of the touch screen display. In the alternative, the web server may have multiple versions of a web page that correspond to multiple different server pressure profiles, and when a web page is requested, the web server identifies a server pressure profile that corresponds to the client pressure profile, identifies a web page that corresponds to the identified server pressure profile, then renders the web page to the user's device.
