Abstract: In an example embodiment, a fast and space-efficient ranking mechanism is used for vertical searches. A precedence is assigned to a plurality of features based on the relative importance of those features to the provider of a vertical search engine. In an example embodiment, this relative importance may be explicitly indicated by the provider of the vertical search engine. A unique data structure may then be created that incorporates the precedence of each feature.

Abstract: Methods and apparatuses are described for identification and traceability of application programming interface (API) functionality in a distributed computing environment. A server retrieves source code comprising API calls from source code repositories, and parses the source code to identify a first set of APIs, each having one or more attributes. The server retrieves API definitions and parses the API definitions to identify a second set of APIs, each having one or more attributes. The server compares the first set of APIs and the second set of APIs to determine matching APIs. Using the matching APIs, the server detects backend systems associated with each API and generates a call graph for each API by traversing abstract syntax trees (ASTs) associated with the source code. The server builds an API model object for each API, comprising the attributes of the API, the detected backend systems, and the call graph.

Abstract: Exemplary embodiments described in this disclosure are generally directed to systems and methods for ensuring password security when starting a vehicle having a keyless engine starting system. In an exemplary method, a computer detects a depression of an engine start push button when no phone-as-a-key (PaaK) device or passive-entry-passive-start (PEPS) key fob is present in the vehicle. The computer responds by executing a verification procedure prior to password validation. The verification procedure can include operations such as determining that no PaaK device or PEPS key fob is present either inside the vehicle or within a defined geofence outside the vehicle. If the verification procedure is successful, the computer displays a prompt upon a display screen for entering of a password. The computer then uses various security measures when verifying the validity of an entered password, followed by displaying of a message indicating acceptance or rejection of the password.

Abstract: An event processing system for distributing a continuous query, and processing events in an event stream, is disclosed. The system can synchronize timestamps across all partitions by adding a heartbeat propagator component propagating a heartbeat signal for silent partitions. The system can further include a timestamp tracker component that tracks the maximum observed timestamp across all partitions for each batch, and sends this to each partition. The system can distribute partitions of the events to the worker nodes, and instruct a heartbeat propagator component to generate a heartbeat for a first worker node corresponding to an event in a different partition. The system receives outputs from the worker nodes and combines these into a single result corresponding to a continuous query. The system can further implement a timestamp tracker to select a highest timestamp value of a previous batch, and send the value to the worker nodes.

Abstract: A system and method for dynamic log management of stream processing in a distributed computing environment, such as, for example, a streaming application or stream analytics system. A streaming application can be deployed or published to a cluster, to execute as a client application. A cluster manager coordinates with worker nodes, to commit tasks associated with the streaming application. If a need arises to generate lower-level log data associated with the streaming application, for example to diagnose an underlying cause of a warning/error message, a configuration job can be committed to the cluster to execute as a separate log-configuration application. The log-configuration application operates with the cluster manager to determine the set of working nodes currently associated with the streaming application, and modify the logger configuration at those nodes, to record or otherwise provide log data according to a modified logging level, for example to provide lower-level log messages.

Abstract: An inter-process communication (IPC) system, includes a first client engine, a first server engine, and a broker engine that is coupled to the first client engine. The broker engine initiates a first timer that is configured to reset when traffic is received from the first server engine while the first server engine is registered with the broker engine and coupled to the broker engine via a communication channel. The traffic that causes the first timer to reset includes at least one of: traffic generated by the first client engine to complete a request, and a first server-to-broker heartbeat message generated by the first server engine. The broker engine determines that the first timer has reached a predefined time amount, and in response, removes the registration of the first server engine and removes the communication channel between the broker engine and the first server engine.
