Abstract: Movement of a user interface (UI) element may be controlled through a magnet based physics model that controls movement of the UI element as if it were under a magnetic force. For a UI element that appears and disappears through device gestures, such as tilts, etc., the UI element may be controlled by one mimicked magnetic force that keeps it hidden and another mimicked magnetic force that keeps it visible, thus allowing the user to control the UI element with intuitive physical gestures using familiar physics-based magnetic behavior.

Abstract: In accordance with a designation of a private alias endpoint as a routing target for traffic directed to a service from within an isolated virtual network of a provider network, a tunneling intermediary receives a baseline packet generated at a compute instance. The baseline packet indicates a public IP (Internet Protocol) address of the service as the destination, and a private IP address of the compute instance as the source. In accordance with a tunneling protocol, the tunneling intermediary generates an encapsulation packet comprising at least a portion of the baseline packet and a header indicating the isolated virtual network. The encapsulation packet is transmitted to a node of the service.

Abstract: Methods and apparatus for client-directed placement of remotely configured service instances are described. One or more placement target options are selected for a client of a network-accessible service based on criteria such as service characteristics of the placement targets. The selected options, including a particular placement target that includes instance hosts configurable from remote control servers, are indicated programmatically to the client. A determination is made that a service instance is to be configured at the particular placement target on behalf of the client. A remote control server is configured to issue administrative commands to an instance host at the particular placement target to configure the service instance.

Abstract: A system that provides services to clients may receive and service requests, various ones of which may require different amounts of work. The system may determine whether it is operating in an overloaded or underloaded state based on a current work throughput rate, a target work throughput rate, a maximum request rate, or an actual request rate, and may dynamically adjust the maximum request rate in response. For example, if the maximum request rate is being exceeded, the maximum request rate may be raised or lowered, dependent on the current work throughput rate. If the target or committed work throughput rate is being exceeded, but the maximum request rate is not being exceeded, a lower maximum request rate may be proposed. Adjustments to the maximum request rate may be made using multiple incremental adjustments. Service request tokens may be added to a leaky token bucket at the maximum request rate.

Abstract: Systems and methods for managing demand for virtual computing resources are disclosed. A demand forecasting service can obtain and analyze historical demand data for purposes of predicting future demand. The analysis includes identifying untargeted demand corresponding to requests for virtual machine instances that can be fulfilled by any availability zone of a set of zones. The demand forecasting service may provide predictions of future demand including information regarding future untargeted demand, thereby enabling efficient allocation of computing resources among various availability zones to meet the future demand.

Abstract: Categorization of data may be performed using rule-based data categorization. Rules may be used to categorize the data into a limited number of categories for a temporary, ad hoc, or updatable process. The rules may be validated to make sure the rules are not ambiguous, contradictory, unattainable, or otherwise ineffective. The rules may include a priority value which may be used as a tie breaker when more than one rule applies to a record. To implement the rules, a lookup flow may be generated to enable rapid or quick traversal of applicable rules for a particular lookup while bypassing at least a portion of the rules. In some embodiments, a record (e.g., an item, etc.) may be categorized during a transaction process to determine a tax classification, a promotion, or another type of classification, which may then be used to complete the transaction.
