Systems and methods for establishing a KVM session are disclosed. The KVM session is designed to provide a communication channel between a client device and a target device without the use of an appliance. For example, the KVM session includes a virtualized KVM session in which the hardware and software used to create the communication channel are stored on a network-based device, as opposed to a multi-port appliance physically connected to the target device. A virtual KVM session eliminates the need for the target device to have a-priori knowledge related to the client device. The virtual KVM session can individually communicate with the client device and the target device, and negotiate a session between the client device and the target device prior to any communication between the target device and the client device. In some embodiments, the virtual KVM session uses out-of-band signaling and SIP to negotiate a session.

A computing system is configured to execute a computer program on a server and to provide a video stream of the program output to a geographically remote client over a communication network. The computing system is further configured to provide executable content of the computer program to the client over the communication network in parallel with the video stream. When a sufficient amount of the executable content has been provided to the client execution of the computer program is transitioned from the server to the client. The transition optionally includes communicating a state of the computer program from the server to the client. The executable content can be provided to the client in an order that is determined based on the state of the computer program. Those parts of the executable content deemed most likely to be necessary to support game play on the client are given priority.

A server system for a map-based social media platform maintains user location information to enable the rendering of friend icons on a map at a corresponding display locations. The system maintains a per user access control list (ACL) that lists all users whose icons can be viewed by a requesting user. The ACL can include a designation of respective display granularity levels for different friend users.

Systems and methods are described for a cyber-physical vehicle management system generated by an Integrated Secure Device Manager (ISDM) Authority configured to manage licensing and approval of Cyber-Physical Vehicle (CPV)s, a public/private key pair and a unique ID for the Authority, create a self-signed Authority token signed by the private key, send the Authority token to a plurality of ISDM Node device configured to verify Module device authenticity and in communication with the Authority, store, by each Node, the Authority token, and mark, by each Node, the Authority token as trusted.

Technologies for time-delayed augmented reality (AR) presentations includes determining a location of a plurality of user AR systems located within the presentation site and determining a time delay of an AR sensory stimulus event of an AR presentation to be presented in the presentation site for each user AR system based on the location of the corresponding user AR system within the presentation site. The AR sensory stimulus event is presented to each user AR system based on the determined time delay associated with the corresponding user AR system. Each user AR system generates the AR sensory stimulus event based on a timing parameter that defines the time delay for the corresponding user AR system such that the generation of the AR sensory stimulus event is time-delayed based on the location of the user AR system within the presentation site.

Replicas are selected in a large distributed network, and the roles for these replicas are identified. In one example, a leader is selected from among candidate computing dusters. To make this selection, an activity monitor predicts or monitors the workload of one or more clients. Different activities of the workload are given corresponding weights. The delay in performing requested activities, modified by these weights is found, and the candidate leader with the lowest weighted delay is selected as the leader.
