In one embodiment, a method comprises: establishing, by a secure executable container executed by a network device, a two-way trusted relationship with a verified subscriber that enables secure user access by the verified subscriber to a secure peer-to-peer data network, including creating a secure public key and a first device identifier uniquely identifying the network device, for insertion into a first device identity container that provides secure identification of the network device in the secure peer-to-peer data network; obtaining a second device identity container for a second network device and comprising a second public key owned by the second network device and a second device identifier uniquely identifying the second network device; and establishing a corresponding two-way trusted relationship with the second network device based on executing a prescribed secure salutation protocol with the second network device based on the second public key and the second device identifier.

Disclosed are embodiments for providing batch performance using a stream processor. In one embodiment, a method is disclosed comprising receiving, at a stream processor, an event, the stream processor including a plurality of processing stages; generating, by the stream processor, an augmented event based on the event, the augmented event including at least one additional field not appearing in the event, the additional field generated by an operation selected from the group consisting of a join or dimensional annotation operation; and emitting, by the stream processor, the augmented event to downstream consumer.

When a user creates a new video exchange session via an online system, the user specifies an activity for the video exchange session. The activity may specify a name for the video exchange session, as well as other thematic content (e.g., visual effects, backgrounds) displayed via the video exchange session. The online system trains a machine learned model that predicts a likelihood that other users will accept an invitation to join the video exchange session if a certain activity is specified for the video exchange session. The online system may then use these likelihoods to rank and sort the activities for the user or to highlight activities with threshold likelihoods.

In one example, a catalog service may use a peer-to-peer network to distribute a data content item across multiple associated user devices. The catalog service may maintain a device group list describing a device group and a content catalog for the device group listing a data content set stored in the device group. The catalog service may identify a content change to the data content set listed in the content catalog at a seed device of the device group. The catalog service may send an update alert to a leeching device of the device group of the content change to trigger the leeching device to receive the content change over a peer-to-peer network between the seed device and the leaching device.

From the enterprise cloud to robot swarms, distributed systems are everywhere. However, because these systems are realized through the careful coupling of disparate technologies (e.g., databases, messaging systems, and application runtimes), they are difficult to create and maintain—even for experienced engineers. This is a problem because the engineers of these systems have to work harder, be better trained, and thus cost more to employ, making it harder to create new products and inventions. A solution herein is a Data Backbone that provides a single medium for processing, storing, and sharing data in near-real-time. By combining these features into a single medium, the Data Backbone consolidates the functionality of several disparate tools into one system.

A method is provided of managing a non-static collection of machines. A first client machine runs a first communication protocol. The non-static collection of machines includes a first linear communication orbit, the first linear communication orbit comprising a sequence of machines that run the first communication protocol, and a second linear communication orbit, the second linear communication orbit comprising a sequence of machines that run a second communication protocol distinct from the first communication protocol. The first client machine receives an instruction from a server to install the second communication protocol, installs the second communication protocol, and then submits a registration request to the server. The first client machine receives, from the server, contact information of a list of potential neighbors. The first client machine then, proactively constructs and maintains a respective local segment of the second linear communication orbit.

A device comprises one or more movable elements and one or more processors. The device is configured to receive a first movement assignment of a first type, receive tracking data from a motion tracking system configured to monitor a position of personnel in a vicinity of the device, plan a first motion for a first movable element of the one or more movable elements based on the first type of the first movement assignment and the tracking data, and execute the first motion.

A peer-to-peer decentralized software configuration manager is described. The peer-to-peer system provides a crowdsourced mechanism to determine and recommend the efficient software configurations. A computer system may subscribe to a ring or group of network connected computers. Once subscribed, the computer system receives a ring data structure that may include one or more software configuration entries. The ring data structure is accessible to each subscribed computer system to the currently installed software configurations and document the relative success or failure of those configurations. The ring data structure may be utilized to identify a more efficient or user friendly software configuration that is currently installed and utilized by a subscribed computer system.

A method and apparatus are provided for connecting a user equipment to electronic devices. The method includes receiving, for a connection to an electronic device, a first broadcast message transmitted by the electronic device according to a first communication mode, wherein the first broadcast message includes information indicating whether the electronic device supports a connection to the electronic device according to at least one of the first communication mode or a second communication mode that is different from the first communication mode; determining whether the electronic device supports the connection to the electronic device according to at least one of the first communication mode or the second communication mode based on the information; and establishing the connection to the electronic device according to the first communication mode or the second communication mode based on a result of the determining.

In an approach for a sparse information sharing system, a processor receives a request from a host owner for a host to become a server of an information sharing system, wherein the request specifies at least one type of information the server will maintain and provide to visitors of the server. A processor syncs the server with other servers of the information sharing system with information of the specified at least one type of information. A processor, responsive to the server receiving updated information from a visitor of the server, notifies the other servers of the updated information.
