Abstract: This disclosure describes, in part, systems and methods for package deceleration and protection while packages are loaded into a bulk box. The packaging assembly includes an interference mechanism attached to a bulk box (e.g., a Gaylord container) by multiple elastic members. As packages are dropped into the bulk box, each package contacts the interference mechanism and the elastic members dampen the kinetic energy of the falling package, thereby reducing its velocity before the package continues into the bulk box.

Abstract: Content can be shared between devices by transmitting an encoded signal that indicates, to each capable device within range, instructions for accessing the content. For example, a first device can emit an encoded audio signal that can be received by any capable device within audio range of the device. Any device receiving the signal can decode the information included in the signal and obtain a location to access the content from that information. Using such an approach, a first user can quickly and easily share content with several users at the same time without any of the receiving users having to determine or navigate to the content being shared. Further, using signals, such as audio signals, provides the ability for most existing devices to easily share content without significant hardware modification or additional expense.

Abstract: When providing a user with native access to at least a portion of device hardware, the user can be prevented from modifying firmware and other configuration information by controlling the mechanisms used to update that information. In some embodiments, an asymmetric keying approach can be used to encrypt or sign the firmware. In other cases access can be controlled by enabling firmware updates only through a channel or port that is not exposed to the customer, or by mapping only those portions of the hardware that are to be accessible to the user. In other embodiments, the user can be prevented from modifying firmware by only provisioning the user on a machine after an initial mutability period wherein firmware can be modified, such that the user never has access to a device when firmware can be updated. Combinations and variations of the above also can be used.

Abstract: A leak detection system may be configured to receive a plurality of memory use reports periodically from a user device. The memory use reports may include an indication of memory that may be used and/or allocated by/to a particular process, such as a process that may currently be running on the user device. The memory use report may further provide a relatively granular view of the allocation of memory associated with the process, such as by type of memory and/or category of memory associated with the process. The leak detection system may use the plurality of memory use reports to generate a memory profile associated with the process and particular memory types and/or categories of memory allocation. By analyzing the memory profiles, the leak detection system may be configured to identify a memory leak associated with the process on the user device.

Abstract: Techniques for predicting and detecting produce quality may be provided. For example, visual or infrared characteristics of a produce item (e.g., skin, shape, wrinkles, and other characteristics of an apple, pepper, etc.) may be compared with ripeness characteristics of the type of produce item (e.g., other apples or peppers). The ripeness characteristics may correspond with the type of produce item at different stages of ripeness along a ripeness regression (e.g., a timeline of the produce item from raw to rotten). One or more ripeness scores of the produce item may be determined along a timeline (e.g., raw at day 1, rotten at day 10, etc.), so that when a user requests a produce item corresponding with a particular ripeness score, the produce item can be provided to the user based in part on the visual or infrared characteristics of the produce item and ripeness regression.

A summary of the portion of the media content is presented to the user via an output device.

Abstract: Hybrid quorum policies may be implemented for access requests to state maintained in a distributed system. An update to state maintained in a distributed system may be sent to multiple nodes in the distributed system maintain the state in order to satisfy a hybrid quorum policy for updating the state in the distributed system. The hybrid quorum policy may include individual quorum policies for multiple quorum sets including nodes of the distributed system. Acknowledgments received from nodes in the distributed system indicating that the update is performed may be evaluated according to the individual quorum policies to determine whether the hybrid quorum policy is satisfied. If the hybrid quorum policy is satisfied, then the update to the state may be considered durable.

Abstract: A block-based storage system may implement efficient replication for restoring a data volume from a reduced durability state. A storage node that is not replicating write requests for a data volume may determine that replication for the data volume is to be enabled. A peer storage node may be identified that maintains a stale replica of the data volume. One or more replication operations may be performed to update stale data chunks in the stale replica of the data volume with current data chunks without updating data chunks in the stale replica of the data volume that are current. Stale replicas that are no longer needed may be deleted according timeouts or the amount of stale data in the replica.
