Abstract: A system and method identify/verify tillage using satellite time series imagery by executing four steps in a loop to improve accuracy over time. First, satellite data are downloaded and preprocessed to retain only “good” images. Second, from fields with validated tillage, the relationship between satellite data and corresponding tillage types is learned to define a tillage prediction model. Next, the knowledge from the previous step is used to make prediction of tillage types for new fields using image statistics of the new field as input. Finally, predicted tillage will be validated manually, if needed using supplementary information, and new fields with validated tillage will be added to the existing validated list to gain new knowledge for further establishing between satellite data and corresponding tillage types.

Abstract: An exemplary transaction sharding method comprises splitting a distributed ledger into a plurality of shards; and storing a shard across the subgroup of computer nodes associated with the shard. Such a method further comprises assigning a new transaction to one of the plurality of shards, wherein assigning the new transaction comprises iteratively choosing one of the plurality of shards; in each iteration, determining a transaction-to-shard score measuring a probability that a subgroup of computing nodes associated with the chosen shard for the current iteration would be involved in a same-shard transaction for the new transaction; in each iteration, determining a latency-to-shard score by estimating a confirmation latency of the new transaction under the chosen shard for the current iteration; and selecting the new transaction to be assigned to the shard based on a combination of the transaction-to-shard score and the latency-to-shard score.

Abstract: Improved techniques for dynamically controlling a program flow of a testing application. The testing application administers an exam on a user interface (UI). A state for each question is monitored, where the state includes a viewed, answered, or unviewed state. A question's state changes based on whether interaction is detected for that question. While the testing application is administering the exam, user input triggers a pause to the administration. A popup window is displayed to show a first list of instructions, a second list identifying exam questions having the “viewed” state, and a confirmation UI element. After the confirmation UI element is selected, the UI is modified by occluding the exam questions, by displaying a resume UI element, and by displaying a timing UI element. Later, the testing application continues the test's administration, but restricts access to certain questions.

Abstract: The subject disclosure is directed towards processing requests for accessing a service provider. After examining at least one security token, a public key and a portion of attribute information are identified. An authentication component is accessed and applied to the public key. A unique user identifier is employed in generating the public key. The authentication component is generated using information from at least one revoked security token or at least one valid security token. The authentication component is configured to prove validity of the at least one security token.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a request to create an identifier for a page that is accessible through a social networking system. Page data that describes the page is determined. One or more identifiers for the page are generated based at least in part on the page data.

Abstract: A cover for protecting an audio port of an electronic device is provided. The cover includes a check valve, a bellows, and an air vent. The check valve moves between a first position to allow audio pressure to exit the audio port and a second position to fluidly seal the audio port. The bellows at least partially surround the audio port when the cover is attached to the electronic device and move the check valve from the first position to the second position in response to a pressure exerted on the bellows. The air vent is attached to the bellows and allows audio pressure to pass through the air vent and to restrict passage of at least some water through the air vent.

Abstract: A retention device includes a ruggedized electrical cable including a first electrical connector at a first end and a second electrical connector at a second end, and a cap including a threaded interior for removably capturing the first electrical connector and the second electrical connector, wherein the threaded interior is configured to screw onto a corresponding threaded surface comprising the exterior of the first end and the exterior of the second end.

Abstract: A protective case for an electronic device having a touch screen and an audio port. The protective case includes a front portion including a rigid frame extending around a perimeter and a screen aperture configured to provide access to the touch screen of the installed electronic device. The protective case includes a back portion removably attached to the front portion and includes a sealing member configured to directly contact a portion of the electronic device. The sealing member has an aperture defining a circumference configured to encircle the audio port of the installed electronic device and form a water-proof seal between the installed electronic device and the sealing member of the protective case. The protective case includes a vent mesh covering the aperture of the sealing member and configured to allow air to pass through the vent mesh and to resist the flow of water through the vent mesh.
