Abstract: Techniques for determining errors or drifts between maps used for updating maps and/or controlling a system which uses the map. In some examples, a first, global, map may be received or determined. Sensor data may then be used to localize a system with respect to the first map and to generate a first trajectory relative to the first map. The sensor data may be used to create a second map and a second trajectory for navigating the system relative to the second map. Differences between the first and second trajectories (or portions thereof), when compared in a common reference frame, may be used as an indication of drift between various processes or errors in the maps and, subsequently, be used for updating the first map and/or controlling the system.

Abstract: A set of construct-modification tags conveying development-phase compiler requests are introduced into source code to facilitate communication between developers, identify areas that need developer attention, send directives to a compiler, and other development features in an integrated development environment, during the software development phase. Tags may incorporate properties, permissions, and generate notifications. Example tags include IGNORE, DEACTIVATE, OPTIMIZE, FIX, ALTERNATE, PROTOTYPE, REQUESTREVIEW, REVIEWED, CANDIDATE, and BESTCANDIDATE. Methods ensure that tags no longer remain in source code once the software development process enters the production phase.

Abstract: Construct-modification tags conveying development-phase compiler requests are introduced into source code to facilitate communication between developers, identify areas that need developer attention, send directives to a compiler, and other development features in an integrated development environment, during the software development phase. A hierarchy of developers and associated permissions is maintained. A tag may be associated with one or more developers as well as one or more permissions. Notifications associated with tags may be issued to one or more developers in response to a conveyed compiler request. General messages to all the developers and personalized messages to one or more developers indicate the presence of tags and need to resolve issues before the software development process enters the production phase.

Abstract: Construct-modification tags conveying development-phase compiler requests are introduced into source code to facilitate communication between developers, identify areas that need developer attention, send directives to a compiler, and other development features in an integrated development environment, during the software development phase. A CANDIDATE tag conveys a request to a compiler to identify multiple candidate constructs, compile each set of candidates or sets of multiple candidates into executables, and profile the compiled executables. Results of the profiling can be compared and a best candidate or set of candidates selected based on one or more of various criteria. A CANDIDATE tag may incorporate properties, permissions, and generate notifications. Methods ensure that tags no longer remain in source code once the software development process enters the production phase.

Abstract: Construct-modified tags conveying development-phase compiler requests are introduced into source code to facilitate communication between developers, identify areas that need developer attention, send directives to a compiler, and other development features in an integrated development environment, during the software development phase. A REQUESTREVIEW tag conveys a request to a compiler to notify a reviewer that source code is ready for review. A REVIEWED tag indicates a review has been performed and may signify code acceptance. Alternatively, a FIX or OPTIMIZE tag may be used to identify further code development requirement. These tags may incorporate properties, permissions, and generate notifications. Methods may facilitate code review and feedback in other aspects. Methods ensure that tags no longer remain in source code once the software development process enters the production phase.

Abstract: Construct-modification tags conveying development-phase compiler requests are introduced into source code to facilitate communication between developers, identify areas that need developer attention, send directives to a compiler, and other development features in an integrated development environment, during the software development phase. A FIX or OPTIMIZE tag identifies a construct to be altered. An ALTERNATE tag identifies an alternate construct to be compiled while ignoring a FIX or OPTIMIZE tagged construct of the same name. The alternate construct may be marked for ignoring once the other tagged construct of the name is fixed or optimized. Each tag may incorporate properties, permissions, and generate notifications. Methods ensure that tags no longer remain in source code once the software development process enters the production phase.

Abstract: Construct-modification tags conveying development-phase compiler requests are introduced into source code to facilitate communication between developers, identify areas that need developer attention, send directives to a compiler, and other development features in an integrated development environment, during the software development phase. A DEACTIVATE tag conveys a request to a compiler to deactivate an associated construct, as well as to find and deactivate dependencies of the construct. A DEACTIVATE tag may incorporate properties, permissions, and generate notifications, including a condition for evaluation, the deactivation conditionally responsive to the result of the condition evaluation. Methods ensure that tags no longer remain in source code once the software development process enters the production phase.

Abstract: Techniques are disclosed relating to controlling performance state of a memory element based on latency information for a processor. In some embodiments, a level of a memory hierarchy is configured to operate at multiple different performance states at different times. Processor circuitry may execute programs that generate requests to access the memory hierarchy. Bandwidth-based control circuitry may generate, based on bandwidth conditions for the processor circuitry, bandwidth performance state signals. Latency-based control circuitry may generate, based on latency information for processor requests to access the memory hierarchy, latency performance state signals. Performance control circuitry may control the performance state of the level of the memory hierarchy based on the bandwidth performance state signals and the latency performance state signals. Disclosed techniques may improve processor performance in certain operating scenarios.

Abstract: A computing system receives, from a client device, a first request for access to a single page application associated with the computing system. A gateway of the computing system intercepts the first request before it reaches a shell service associated with the single page application. The gateway sends a second request for the single page application to the shell service. Based on the single page application request, the gateway determines that the shell service is experiencing a failure. Responsive to determining that the shell service is experiencing a failure, the gateway retrieves, from a content delivery network, a uniform resource locator (URL) associated with a time-lapse hypertext markup language (HTML) of the single page application. The gateway redirects the client device to the time-lapse HTML of the single page application using the URL.

Abstract: A method and system for streaming management information base data using simple network management protocol is disclosed. The system includes a manager device and an endpoint device, which runs a SNMP agent and SNMP proxy. The SNMP proxy retrieves MIB data from the SNMP Agent associated with the endpoint device, wherein the MIB data comprises a full MIB sub-tree and differential MIB sub-trees. MIB views comprising MIB variables of interest associated with a full MIB sub-tree and differential MIB sub-trees are created based on a predetermined configuration. The SNMP proxy stores the MIB views and corresponding MIB data in a data store and compresses the MIB views and MIB data into files. Compressed file of the MIB view with MIB data associated with full MIB sub-tree are sent to the manager device in an initial stream. Further, the endpoint device streams compressed file of the MIB views with MIB data associated with the differential MIB sub-tree to the manager device on receiving a request.
