Abstract: In various example embodiments, a system and method for consistent schemaless and scalable database storage are described herein. A data object is generated. The data object corresponds to a column of a table from a database. The data object includes information regarding an order that is placed over a network publication system. The data object is stored in the column of the table in the database. A request to access the data object is received from a device of a first user. The data object is transmitted to the device of the first user. The data is kept coherent during concurrent updates by using optimistic locks. The data is kept backward and forward compatible utilizing intermediate data structures common to both versions of the software. The data is kept searchable by using lookup indexes. The storage system is kept scalable by sharing data across many databases.

Abstract: Systems and method directed to performing a single checkout process using multiple currencies are described. More specifically, a first item total in a first currency type may be displayed at a first location in a user interface and a second item total in a second currency type may be displayed at a second location in the user interface. In response to receiving a determination of a third currency type associated with a buyer of one or more items associated with the first currency type and one or more items associated with the second currency type, a transaction total including a currency transaction fee associated with converting the first currency type to the third currency type and a second currency transaction fee associated with converting the second currency type to the third currency type is displayed at the user interface.

Abstract: Aspects of the present disclosure relate to transaction security techniques. In examples, a resource platform causes a set of executable verification instructions associated with an authorization processor to be executed by a user computing device. The verification instructions may be encrypted by the authorization processor for decryption by the user computing device. The verification instructions may generate verification information associated with the user computing device. In some instances, the verification information may be encrypted for decryption by the authorization processor. The encrypted verification instructions may be provided to the authorization processor (e.g., via the resource platform), such that the authorization processor may provide an indication to the resource platform as to whether the verification is verified.

Abstract: The disclosed system and methods adjust one or more parameters affecting the purchase of one or more items and change a buyer interface in order to display the consolidated parameter to a buyer. Example embodiments include a machine-implemented method for detecting an edit to the shopping cart, conducting a complex parameter editing simulation based on data accessed from multiple databases, adjusting a parameter associated with an item in the shopping cart, and adjusting and displaying a cart total to the buyer. The system can further receive an indication to checkout the shopping cart and edit complex parameters during checkout accordingly.

Abstract: A marker airbrush device for transferring marking solution from a marking device onto a writing surface using air is provided. The airbrush device includes a housing with an air outlet, a dual-action trigger for controlling an amount of air travelling through the air outlet, and a marker positioner coupled to the housing. The dual-action trigger may be either pushed down or pulled back to control air flow through the air outlet. The marker positioner positions a marking device relative to the air outlet such that air traveling through the air outlet contacts at least one surface of the marking device to transfer marking solution onto a writing surface. The marker positioner may include a rotatable collar that couples the marking device within the marker position and creates a seal around the marking device to prevent pressurized air from escaping around the marking device.

Abstract: A marker airbrush device for transferring marking solution from a marking device onto a writing surface using air is provided. The airbrush device includes a housing with an air outlet, a trigger for controlling an amount of air travelling through the air outlet, and a marker positioner coupled to the housing. The marker positioner positions a marking device relative to the air outlet such that air traveling through the air outlet contacts at least one surface of the marking device to transfer marking solution onto a writing surface. In embodiments, rotation of a portion of the marker positioner advances and/or retracts the marking device with respect to the flow of air through the air outlet, thereby altering the angle and/or amount of air that contacts the marking device during spraying.

Abstract: A retention, release, and separation device is disclosed. The device includes a clip to secure a component and a capturing sleeve to secure the clip and prevent release of the component. The capturing sleeve can alternately facilitate displacement of the clip to release the component. The device also includes a separation piston that provides a separation force to the component to actively separate the component from the device upon release of the component. Additionally, the device includes a fluid source to provide a fluid pressure sufficient to displace the capturing sleeve and the separation piston, and to generate the separation force.
