Abstract: In various example embodiments, a system and method for generating a message that identifies an item listing are presented. A message that identifies a first item listing is received from a client device. A determination of a price of a first item from the first item listing is identified. A second item listing of a second item is identified, the second item being priced lower than the price of the first item. A message that identifies the second item listing is generated. Display of a message that identifies the second item is caused.

Abstract: A system and method for conducting battery charge aware communications is disclosed. A system receives a content request from a client device, wherein the content request indicates one or more content items. The system retrieves the one or more requested content items from a content database at the system. The system determines whether the content request includes current remaining battery power data for the client device. In response to determining that the content request includes the current remaining battery power data for the client device, the system determines whether a current remaining battery power is below a predetermined threshold. In response to determining that the current remaining battery power is below the predetermined threshold, the system analyzes the one or more requested content items to determine core content sections. The system transmits the determined core content sections to the client device.

Abstract: Methods, systems, and apparatus for controlling an inventory of an item for sale are described. A demand for the item and an inventory of the item are projected. A recommended future time period for listing the item for sale is determined based on the projected demand and the projected inventory and is provided to a user listing the item on an online marketplace. A user-selected listing time period is obtained and an item record generated comprising an item description, the item record being associated with the user-selected listing time period.

Abstract: A confidential information exchange between a sender and a receiver may be conducted without the use of encryption keys. The information is coded with a Challenge-Response Table that is shared between the sender and the receiver. Rather than sending a challenge and then waiting for a response, the challenge and response are both sent by the sender of the information. The information sent comprises an index with a challenge and a response from the Challenge-Response Table. Upon receiving the coded information, the receiver uses the Challenge-Response Table to decode the information by using the index to locate the challenge and its valid response. Upon determining that the challenge and the response are correct, a first decoded answer is determined. Upon determining that either the challenge or the response, or both, are incorrect, a second decoded answer is determined.

Abstract: A system to provide a dynamic pricing model is described. An item listing in an on-line trading platform may be designated as being a subject to dynamic pricing functionality. When an item listing, that has a dynamic pricing option enabled, is selected for inclusion into the search results, a dynamic pricing system determines whether the search results are to be ordered according to respective prices associated with the listings and whether the listing is at the top of the list of the search results. If the original price associated with the listing is such that the listing would not be placed at the top of the list of the search results, the dynamic pricing system may reduce the price associated with the listing such that, based on the reduced price value, the listing can be positioned at the top of the search results list.

Abstract: The disclosed technology generates two relative prime numbers and, then, using the relative prime numbers converts a super-increasing (SI) knapsack into a non-super-increasing (NSI) knapsack. The NSI knapsack becomes a public key and the corresponding SI knapsack, along with the two relative prime numbers, becomes a private key. A message is encrypted using a subset S of the private key that totals a number N. The message, the public key and the number N are transmitted to a recipient, who knows the value of the two relative prime numbers. The recipient uses the relative prime numbers to convert the public key into the private key and, then, generates the subset S by solving the private key with respect to the number N. Using the subset, the message is decrypted.

Abstract: Disclosed herein are methods, systems, and computer program products for managing data within a file system. In embodiments, the method includes determining the location of data within a file to be modified, modifying the data within the file, and adjusting a pointer to point to the data block containing the modified data. The data within a file may be modified by deleting data from the file or inserting new data into the file. New data may be inserted into a file by writing the data into new data blocks and then adjusting the pointers to point to the location of the new data blocks. An example method may also include determining whether data blocks are incomplete blocks and identifying the incomplete blocks by negating the value of the pointers to those blocks.

Abstract: The invention includes a method for encrypting and transmitting a message M from a first location to a second location. Random numbers P and Q are initially selected, each of them being either a prime or a non-prime number. P and Q are both furnished to a sender and a recipient at the first and second locations, respectively. A client at the first location generates an encrypted message E, which is the remainder left when a modulus operator divides a first quantity, equal to M multiplied by P to the i power, where i is a selected number, by a second quantity equal to (PQ?1). A tuple comprising E and i is transmitted from the first location to the second location, and a second data processing system at the second location to determines the message M from E, i and Q.
