Abstract: A shack-sensor apparatus may include a sensor configured to detect a positional state of a hard-drive drawer. The shock-sensor apparatus may also include a mounting component coupled to the sensor and configured to mount the sensor in a location to monitor the positional state of the hard-drive drawer. In addition, the shock-sensor apparatus may include a computing module, electronically coupled to the sensor, that analyzes sensor data provided by the sensor to predict a shock event of the hard-drive drawer and send, in response to predicting the shock event, a signal to at least one hard drive in the hard-drive drawer to prevent damage to the hard drive. Various other apparatuses, systems, and methods are also disclosed.

Abstract: A computer-implemented method for increasing the longevity of archival tape may include suspending, by a scheduling computing system, an initiation of a read/write process for an archival tape. The method may also include reading a tape status stored on a status tag embedded on a cartridge of the archival tape. In addition, the method may include deducing, by the scheduling computing system, a health status of the archival tape from the tape status. Furthermore, the method may include adjusting, by the scheduling computing system, a read/write policy of the archival tape based on the health status. Finally, the method may include completing the read/write process of the archival tape based on the adjusted read/write policy. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: An online system identifies seed users with a high value score to a third party system. The online system identifies features of each of the seed users. A weight for each of the identified features is identified. The identified features are divided into a plurality of buckets, each bucket indicating a property associated with one or more of the identified features. Each bucket is ranked according to the weights of the identified features in each bucket. The online system identifies an additional user that has a threshold measure of similarity the seed users. The online system transmits a content item to the additional user for presentation. Additionally, the online system transmits one or more third party-presentable factors based on the bucket having the highest rank to the third party system, the third party-presentable factors indicating a reason as to why the additional user was presented with the content item.

Abstract: In an embodiment, a power management system includes a detection unit configured to detect a power interruption to a power supply. The system further includes a communication interface configured to, in response to the detected power interruption, provide a message regarding the detected power interruption. In response to the detected power interruption, a computer network switch provides notifications to a plurality of servers connected to the switch to allow the plurality of servers to prepare for a loss in power.

Abstract: In one embodiment, the system identifies one or more geographic areas covered by a communication network. The system determines, for each identified geographic area, a congestion metric for the identified geographic area based at least on a difference between a first and second reference point on a network speed curve, wherein the network speed curve represents download speeds for a volume of traffic in the identified geographic area. The system identifies one or more network traffic congestions in one or more of the identified geographic areas based on a comparison of the respective congestion metrics of the identified geographic areas to a threshold congestion metric. The system sends, to one or more operators of the communication network, one or more alerts about the identified network traffic congestions.

Abstract: An online system predicts the user's activity on the online system during a future time interval (e.g., the next day). The system collects activity data, such as actions that the user has taken on the system. The system predicts whether the user is likely to be active during the future time interval based on features extracted from the activity data. This system determines selection of notifications and delivery of notifications based on the predicted time when the user is likely to be active on the online system. The system further records the user's past interactions with notifications, such as whether the user viewed the notification, whether the user interacted with a content item associated with the notification, and so on. If system determines a rate of delivery of notifications to the user based on the frequency of past user interactions with notifications.
