Abstract: Data characterizing historical skills-based gaming metrics for a first user and historical skills-based gaming metrics for at least one second user is accessed. Using the accessed data and a set of rules, a targeted advertisement to present to the first user is determined. The targeted advertisement specifies at least one skills-based game and a characterization of the at least one second user's historical skills-based gaming metrics. The targeted advertisement is generated. Data characterizing the targeted advertisement is provided. Related apparatus, systems, techniques, and articles are also described.

Abstract: A user-activity video signal can be received. The user-activity video signal can comprise a video capture characterizing a user's interaction with a software application on a client. The software application can have an interface display space on the client and the software application can execute on the client in operation with at least one remote backend computing system. Backend user interaction data corresponding to the user's interaction with the software application as generated by the at least one remote backend computing system can be received. A new video comprising a plurality of divided segments of the user-activity video signal can be generated automatically using the backend user interaction data and a plurality of predefined rules. The new video can be provided. Related apparatus, systems, techniques, and articles are also described.

Abstract: A retractable storage system for handheld electronic device has one or more storage chambers to house a retraction mechanism and/or a battery. At least one accessory station structured on the housing member of the device has an aperture for arresting, dispensing and/or charging at least one accessory item, such as a wireless earbud or e-cigarette. The retraction mechanism retrieves and dispense the stored accessory item through the accessory station.

Abstract: Data characterizing a quantifiable outcome for each of a plurality of game trials can be accessed. Each game trial can be associated with one of a plurality of players and a game. The game can be a digital game played on a computing platform. Using the accessed data, a first variance measure of the quantifiable outcome for all game trials associated with the plurality of players can be computed. For one or more of the plurality of players and using the accessed data, a second variance measure of the quantifiable outcome for the game trials associated with the one or more of the plurality of players can be computed. Based on at least the first variance measure and the second variance measure, a skill factor for the game can be computed. Data characterizing the skill factor can be provided. Related apparatus, systems, techniques, and articles are also described.

Abstract: A retractable storage system for handheld electronic device comprises a removable panel with one or more storage chambers for storing an accessory item, such as a wireless earbud, cabled earbud, headphone cable or e-cigarette, and a retractable mechanism to retrieve and dispense the stored accessory item through an accessory station. The removable panel can be replaced with another removable panel configured with different structure to store different accessory item, such as a battery to charge a wireless earbud or e-cigarette.
