Abstract: In an approach to identifying program bugs, one or more computer processor detect a first crash in a try block. The one or more computer processors determine a catch block executed in response to the crash. The one or more computer processors collect a first set of environment information based on the catch block. The one or more computer processors create a first breakpoint where the first crash occurs. The one or more computer processors detect a second crash in the try block using a first pattern associated with the first crash based on the first set of environment information. The one or more computer processors collect a second set of environment information based on the catch block. The one or more computer processors create a second breakpoint where the second crash occurs.

Abstract: A system and method for managing an ad hoc network are disclosed. A boundary for an area to be monitored is defined for the ad hoc network. A number of devices connect with each other to form the ad hoc network. Devices can enter and leave the network as they come into proximity with one of the members of the network. Data is transmitted between the members of the network. This data can include a carrier rating and a data rating about each member of the network as well as data about other devices that the transmitting device had previously come into contact with. The data held by one member about other members is stored and can later be retrieved.

Abstract: A method, executed by a computer, includes repeatedly collecting execution information for a code unit to produce collected execution information for the code unit, generating an execution profile for the code unit based on the collected execution information, comparing current execution information for the code unit with the execution profile, and informing a user if the current execution information does not conform to the execution profile. A computer system and computer program product corresponding to the above method are also disclosed herein.

Abstract: An apparatus and method uses location based authentication of a user accessing a virtual machine (VM) by using the physical location of the virtual machine as a criteria for the authentication. When a user requires a logical partition to run in a known, specified physical location, the user specifies the physical location when the VM is created. The specified physical location is then incorporated into the user authentication process. Users are challenged and must know the physical location in order to be authenticated to the system. When a “disruptive event” in the cloud environment occurs that necessitates moving the VM to another location, the original physical location is stored so the virtualization manager later can automatically relocate the VM back to its original physical location.

Abstract: Embodiments of the present invention disclose a method, computer system, and a computer program product for automatically presenting enhanced content on a mobile device based on user focus. The present invention may include presenting content on a screen. The present invention may include determining that a user is focused on a specific screen region of the presented content. The present invention may include generating a zoomed view of the presented content based on the specific screen region the user is focused on. The present invention may include presenting the zoomed view on the screen. The present invention may include determining that the user reacted positively to the zoomed view. The present invention may include, in response to determining that the user reacted positively, determining enhanced content based on zoomed content displayed in the zoomed view. The present invention may include presenting the enhanced content on the screen.

Abstract: Systems, methods, and computer program products to perform an operation comprising receiving, by a mobile device, an indication to output a notification, determining an orientation of the mobile device, determining a location of a wearable device relative to the mobile device, and selecting, based on the determined orientation of the mobile device and the location of the wearable device relative to the mobile device, at least one of the mobile device and the wearable device to output the notification.

Abstract: A host swap hypervisor provides a high availability hypervisor for virtual machines on a physical host computer during a failure of a primary hypervisor on the physical host computer. The host swap hypervisor resides on the physical host computer that runs the primary hypervisor, and monitors failure indicators of the primary hypervisor. When the failure indicators exceed a threshold, the host swap hypervisor is then autonomically swapped to become the primary hypervisor on the physical host computer. The original primary hypervisor may then be re-initialized as the new host swap hypervisor.

Abstract: Embodiments presented herein describe techniques for tracking operators of a distributed computing environment (e.g., a streams processing environment) using metadata. During execution of a distributed application of the computing environment, a tracker tool monitors a plurality of operators of the distributed application. Each of the operators stores one or more specified metadata values associated with the operator. For each operator, the tracker tool retrieves the one or more specified metadata values associated with the operator. Upon determining that one of the one or more specified metadata values do not comply with a corresponding expected metadata value, the tracker tool generates an indicator for the operator. The indicator includes information describing the one or more specified metadata values.

Abstract: A cloud manager uses streams to monitor state of the cloud. A cloud state streaming policy specifies state data to stream, along with one or more initial operators for processing the streams. An archive mechanism allows archiving the streamed data when specified data in the streams exceeds one or more defined thresholds. A user interface allows adjusting the streaming of cloud state data to focus on data of interest to a user. The cloud manager thus allows a user to determine state of a cloud via the streamed state data.
