Abstract: Validating programming code by providing a data schema including registered data types, identifying a data object as defined according to a registered data type of the schema; and checking attempts to access the data object according to the registered data types of the data schema, at compile time.

Abstract: Provided is software versioning that allows a set of features to be selectively enabled and/or disabled based on a value of a switch associated with each feature of the set of features. The software versioning includes an administrator component that receives a change to a switch associated with at least one application. A toggle component generates a configuration notice based on an indication of the change to the switch. A tool kit component facilitates implementation of the change at the application based on the configuration notice received from the toggle component.

Abstract: An instrumentation analysis system processes data streams by executing instructions specified using a data stream language program. A user interface allows users to specify data stream language programs. The user interface presents widgets to the user to specify various components of a data stream language program, including a filter expression, an analytical function representing an aggregation or transformation, and so on. The user interface allows users to specify an expression based on results of previously specified data stream language programs. The instrumentation analysis system processes the data stream language programs specified by the user to generate a set of result data streams and plots the result data streams, for example, on a screen of a client device.

Abstract: Method and apparatus for a parallel, metadata-based trace analytics processor is disclosed.

The result is the ability to get analytics results quickly, efficiently, and in real time.

Abstract: A computer system includes a processor, a communications subsystem, and a non-transitory computer-readable storage medium. The computer-readable medium stores instructions that when executed by the processor adapt the computer system to receive an indication of a second device selected, at a first device, for update; send an indication signalling the second device to send state information about the second device; receive state information about the second device; determine, based on the state information, that the second device is ready to perform an update; send, to the first device, an indication that the second device is ready to perform the update; receive, from the first device, an indication to update the second device; and, send a corresponding indication to the second device. The second device is configured to begin updating in response to such an indication without any direct interaction with it. Related methods and computer-readable media are also described.

Abstract: Best known configurations can be automatically created for particular platforms. An update tool can be installed on end user devices and can include a health monitor engine that creates health reports for drivers and/or firmware installed on the corresponding end user device. The health reports generated on the end user devices can be provided to a best known configuration engine that can evaluate them to calculate a best known configuration for each platform. The best known configurations can then be distributed to the update tool on the end user devices to cause them to configure the end user devices to match the corresponding best known configuration.

Abstract: An embodiment includes storing original environment data in a memory of a computing device, then sourcing a script in a child command shell that includes an environment variable set-up command for setting an environmental characteristic of a new computing environment associated with the child command shell. The new environment data is also stored in the memory of the computing device that defines the new computing environment associated with the child command shell. The original computing environment is then restored by terminating the child command shell and returning to the target command shell. The original environment data is compared to the new environment data to determine the differences between the two environments, and the original computing environment is then modified to match the new computing environment created by the sourced script.

Abstract: Aspects directed towards deploying a software-defined data center (SDDC) are disclosed. In one example, an SDDC software package is received at a public cloud computing environment in which the SDDC software package facilitates creating an SDDC on a plurality of host computers. A first test of the SDDC is then performed via a first testing server and a second test is performed via a second testing server. For this example, the first test is a generic test of the SDCC corresponding to a generic deployment of the SDDC software package on the plurality of host computers, whereas the second test is a custom test of the SDCC corresponding to a custom deployment of the SDCC software package. A usability of the SDCC is then validated based on at least one of the first test or the second test.

Abstract: Methods and systems are presented for testing software applications in a production-like environment that simulates real-world failures of production environments. A production environment has production applications and databases configured to process user requests from users for conducting transactions with a service provider. A testing system provides an intermediate interface that enables a software application operating in the test environment to access at least one of a production application or a production database. The intermediate interface can be configured based on different failure configurations to simulate production component failures in the production environment. Failure injection and randomized failure modes can be employed, including for network-related failures (latency, dropped packets, connections, etc.) that might occur in the production environment.

Abstract: Systems and methods for syntactical change-resistant code generation are described. A code generator can generate syntactical change-resistant code from original code and new code, where the new code may be intended as a replacement or update for the original code. The code generator can determine, for code portions and/or sub-portions of the new code, whether or not semantic, syntactic, and structural differences from the original code exist. The code generator can generate the syntactical change-resistant code to leverage and include in the syntactical change-resistant code portions and sub-portions of the original code that have been used and tested, so as to improve reliability of the syntactical change-resistant code.

Abstract: The invention provides, in some aspects, methods of optimizing an app for execution on a client device by identifying components of the app used in such execution by a user having a designated role who accesses the app for download via a designated portal. A component can be, for example, a source code file or portion thereof, including, for example, a portion defining a widget or other user interface element. For each component, the method (i) identifies source code files on which execution of that component depends, e.g., in connection with execution of the particular app by the particular user, and (ii) generates a dependency-ordered stack of the source code files for that component. In further accord with those aspects of the invention, the method combines the dependency-ordered stacks into a single such stack and transfers the source code in an order specified by that stack to the client device for loading and execution.
