A computer controls power distribution. The computing system determines a power budget for a portion of a topography for a power delivery system. The computing system generates a pool of worker programs for the portion of the topography. The computing system generates a first number of power management tasks to manage power consumption in the portion of the topography based on the power budget. The computing system sends the first number of power management tasks to at least one worker program included in the pool of worker programs.

In one embodiment, a method includes modifying at least one aspect of a notification to be displayed on a first portion of a touchscreen of a device in response to a determination that a second portion of the touchscreen includes and/or overlaps with the first portion of the touchscreen. The second portion of the touchscreen os defined by a point on the touchscreen expected to be imminently touched by a user and predetermined areas of the touchscreen adjacent to and surrounding the point.

Adaptive notification modifications for touchscreen interfaces

For location-based communication with mobile devices, a set of callee conditions is received at a caller's device, which has to be satisfied by a callee according to information descriptive of a condition of the callee. The state information is distinct from the location and a time of the callee's presence at the location. An evaluation is made that each device associated with each potential callee in a first subset has been present at the location at a specified time, and that each potential callee in the first subset satisfies the set of callee conditions. At the caller's device, an instruction is received for making a telecommunication call to a device of a potential callee in a first subset. The call is initiated from the caller's device to mobile devices associated with the first subset of potential callees.

Callee condition based communication with mobile devices

A processor may initiate a first verification event. The first verification event may be triggered when a mobile device begins generating new data at a first time. The processor may determine, in response to the first verification event, that the mobile device is above a threshold limit of available storage. The processor may analyze one or more applications on the mobile device. The processor may automatically remove a first re-downloadable portion of a first application binary interface associated with a first application from the mobile device. The processor may store the generated new data on the mobile device.

Instant storage reclamation ensuring uninterrupted media recording

At an application executing in conjunction with a vSwitch in a host system, using a processor assigned to the vSwitch in the host system, a flow of a number of packets is received from a VM. At the application, a set of CWND values is computed using a corresponding set of congestion control algorithms. At the application, a determination is made whether any of the CWND values in the set of CWND values match the number of packets in the flow within a tolerance value. In response to a CWND value in the set of CWND matching the number of packets in the flow within the tolerance value, a conclusion is drawn that a type of the congestion control algorithm which computed the matching CWND value is the type of a local congestion control algorithm implemented within the VM.

Identifying a local congestion control algorithm of a virtual machine

For variable resolution rendering of objects, a processor determines an aggregate familiarity of a user with an object based on at least one of a common familiarity of the object, a content-specific familiarity of the user with the object, and a subjective familiarity of the user with the object. The processor further, in response to the aggregate familiarity satisfying a render policy, reduces a render resolution of the object.

Variable resolution rendering of objects based on user familiarity

A type of a request that is currently being processed at a system is determined. A distribution is selected from a set of processing time distributions, the distribution forming a model that is applicable to the type. A threshold point is computed for the model. A processing time that exceeds a threshold point processing time is regarded as exhibiting tail latency. Tail latency includes a delay in processing of the request due to a reason other than a utilization of a resource of the system exceeding a threshold utilization and a size of a queue in the system exceeding a threshold size. An evaluation is made that the request will experience tail latency during processing at the system and the processing of the request at the system is aborted. The request is offloaded for processing at a peer system in a load-balanced group of systems.

Tail latency-based job offloading in load-balanced groups

A plurality of SYN packets is sent from a first system, each of the plurality of SYN packets traverses a different path in a first set of paths between the first system and a second system in a multipath data communication network and includes a unique source identifier. From a plurality of SYN-ACK packets, a SYN-ACK packet is selected that is first to arrive at the first system. Each SYN-ACK packet includes a unique source identifier of a selected SYN packet. A path is configured corresponding to the selected SYN packet, as an outbound path from the first system. A path corresponding to the selected SYN-ACK packet is configured as an inbound path to the first system. A session between the first and the second systems is established using the outbound and inbound paths.

Path selection using TCP handshake in a multipath environment

A determination is made at an application executing in conjunction with a switch that a request packet sent to a virtualized computing entity (VCE) connected to the switch should be offloaded to a second VCE. A destination of the request packet is changed from the VCE to the second VCE, to form a first modified request packet. An evaluation is made whether a response packet from the second VCE, which is responsive to the request packet, is usable in the data communication with a sender of the request packet. When the evaluating is affirmative, the first modified request packet is caused to be transmitted from the switch to the second VCE.

Offloading at a virtual switch in a load-balanced group

A method, system, and computer program product for scalable and self-healing architecture for client-server operations in transient connectivity conditions are provided in the illustrative embodiments. An application in a second system receives a request from a first system, the request requesting data from a type of service. A first response responds to the request. The request is queued in a service queue corresponding to the type of the service, to make the request available to a third system that provides the type of the service. A notification is received that a second response from the third data processing system has been posted into a session specific queue, the second response being responsive to the request. In response to another request received from the first system, a third response is sent to the first system, the third response including the data from the second response from the session specific queue.

In one embodiment, a method includes determining that a notification is to be displayed on a first portion of a touchscreen of a first computing device. The method also includes determining a point on a surface of the touchscreen in which a user of the first computing device intends to imminently touch the touchscreen. Also, the method includes determining whether a second portion of the touchscreen includes a currently-displayed interactive touch component, the second portion of the touchscreen being defined by the point and predetermined areas of the touchscreen adjacent to and surrounding the point. Moreover, the method includes modifying at least one aspect of the notification in response to a determination that the second portion of the touchscreen includes and/or overlaps with the first portion of the touchscreen. Additional embodiments for adaptively modifying notification settings for implementation on a touchscreen display are also described.

At an SDN controller executing using a processor and a memory, a tracing packet is configured with a default value in a tag field. The tracing packet is inserted from the SDN controller into the SDN at a switch in the SDN. A returned packet and a port identifier is received at the controller, from the switch, the returned packet including a modified content in a location of the tracing packet that is different from the tag field. The port identifier corresponds to a port of the switch on which the switch received the returned packet from an middlebox. A function of the middlebox is identified by analyzing a modification applied to the modified content by the middlebox. The function of the middlebox and a location of the middlebox in the SDN are saved. The location includes the port identifier and an identifier of the switch.

In one example implementation according to aspects of the present disclosure, a computer-implemented method includes receiving, at a user device, an input. The method further comprises determining, by a processing device, whether a gaze of a user is directed to the user device. The method further comprises, based at least in part on determining that the gaze of the user is directed to the user device, authorizing the input at the user device.

Preventing unintended input

At an application executing in conjunction with a vSwitch a determination is made that a first flow from a first VM is experiencing congestion. The first flow is selected for throttling. a second flow is also selected for throttling, the second flow using a portion of a network path used by the first flow in a data network. At the application, a total CWND adjustment is distributed between the first flow and the second flow. A first CWND value associated with the first flow is adjusted by a first portion of the total CWND window, and a second CWND value associated with the second flow is adjusted by a second portion of the total CWND window.
