Abstract: Disclosed are various embodiments for identifying fault injection impact zones. A test for an application can be received from a test service. An application schema can then be created that represents the systems or services that are involved in the execution of the application. Applications with a similar application schema are then identified using a first machine-learning model. A subset of the plurality of applications that have experienced a similar test are then identified with a second machine-learning model. Log files associated with each of the subset of applications are then analyzed to identify errors that occurred during the similar test. Each of the identified errors are then provided to the test service in response to receipt of the test.

Abstract: Disclosed are various embodiments for automated testing of systems and applications. A first computing device may be in data communication with a second computing device. The first computing device can receive a fault instruction specifying receive a fault instruction specifying a fault to inject into a virtual compute instance, parameters for the fault, a duration of the fault, and an identifier of the virtual compute instance. The first computing device can then send a command to a second computing device that hosts the virtual compute instance, wherein the command specifies at least the fault, the parameters for the fault, and the virtual compute instance. In turn, the second computing device can receive the command from the first computing device, save a pre-fault state of the virtual compute instance, and then introduce the fault into the virtual compute instance.

Abstract: Disclosed are various embodiments for automated testing of systems and applications. A computing device can receive a command to execute a test, the test comprising at least one fault instruction and an alarm, the alarm being specified as an evaluation criterion for the test. The computing device can then send the fault instruction to a fault injection service. Next, the computing device can receive a message from a monitoring service, the message indicating that the alarm has been triggered subsequent to sending the fault instruction to the fault injection service. Subsequently, the computing device can determine that the test has failed based at least in part on the alarm being triggered. Finally, the computing device can send a failure notification to a predefined recipient in response to detecting that the alarm has been triggered.

Abstract: Disclosed are various embodiments for automated testing of systems and applications. A computing device can be configured to receive a fault instruction specifying a fault to inject into one or more service requests sent to a service, parameters for the fault, and a duration of the fault. The computing device can then instantiate a service proxy and send a command to the service proxy, wherein the command specifies at least the fault and the parameters for the fault. Next, the computing device can cause service requests sent to the service to be redirected through the service proxy. The service proxy can receive a service request and generate a response to the service request that contains the fault based at least in part on the parameters for the fault. The service proxy can then return the response to the service request.

Abstract: There is provided A process for producing a biocompatible soil mixture from cremated ash remains, the process comprising: mixing cremated ash remains with a soil base material and a nutrient composition to produce a pre-conditioned mixture, the nutrient composition comprising at least one of paramagnetic material, soil conditioner and fertilizer; and conditioning the pre-conditioned mixture using a microbial conditioner to adjust the adverse chemical properties of the cremated ash remains biologically to produce a conditioned soil mixture being biocompatible for a legacy tree, wherein the pre-conditioned mixture comprises less than 10% of the cremated ash remains by volume.

Abstract: The present invention provides a portable and compact battery-powered stereo speaker assembly that incorporates a DC to DC converter, which enables power from the internal stereo speaker assembly battery to charge an interconnected hand-held device, such as a smartphone, through a USB connection, thereby extending the time that the device can be used untethered from the AC power grid. A DC to DC converter enables the charging function can be implemented even if the speaker assembly is not connected to the AC power grid, and even if the battery of the stereo speaker assembly is not fully charged. The stereo speaker assembly also incorporates Bluetooth connectivity, a proprietary open wireless technology standard, developed by Ericsson in 1994, employing frequency-hopping spread spectrum radio transmissions in the ISM band from 2400-2480 MHz.

Abstract: A method and a digital locker system for providing digital locker services are described. Content offers come from external sources and locally hosted sources. Content offers from external sources are received and processed in a content offer processor along with catalog information. Content offers from locally hosted sources are retrieved and catalog information is generated accordingly. Both types of content offers are aggregated and prepared for storage in a content offer cache, which are then used for providing services, such as content query, to users. Content acquisition and playback requests from users are handled according to the provider of the requested content.

Abstract: A display system which includes a display controller, a display unit, and a light source is disclosed. The display controller includes a processor unit, a memory device, a voltage source and, optionally, a light source control unit. The display unit includes an array of pixel cells and circuitry to receive logic and control voltages and data and operate the display, a transparent counter electrode, and a liquid crystal layer disposed between the two alignment layers. The pixel cell includes a storage element, a DC balance control switch, a pixel voltage override circuit, an inverter able to select between two voltages available to it, and a pixel electrode/mirror. In different modes of operation the pixel mirror voltage may be determined by the storage element or by the pixel voltage override circuit. The display system may display images in one period and reset to a fixed state in another period.
