A method and system for optimizing channel access scheduling for multiple wireless computing devices over a wireless network improves channel access efficiency with respect to a primary channel. An access point, or host computer, includes a host transceiver for receiving control information from the wireless computing devices over a low power channel. Upon receiving the control information, the access point applies a scheduling algorithm to schedule channel access for the wireless computing devi...

An improved method and system for optimizing the allocation of bandwidth within a network system is presented. When a client device is engaged in communication with a remote computing device, an access point measures the throughput of the connection between the client device and the network. If the throughput is less than the amount of bandwidth reserved for usage by the client device, the access point adjusts the amount of bandwidth allocated for the client device to an amount equivalent to the...

A method for refinishing a countertop in order to achieve a granite, a marble, or other desired look uses an oil-based paint having a glaze therein applied as a base coat to a countertop that has been prepared smooth and taped as needed. Once the base coat dries, one or more additional coats each coat may be the same color as the other additional coats or different from the other coats, and each additional coat being a different color from the base coat. One of three applicators is used for the ...

An index tuning wizard produces a fast and reasonable recommendation identifying database indexes to use given a specified workload. A query optimizer is used to determine the expected usefulness of potential indexes for the specified workload by taking cost of queries in the workload into account. A cost based pruning of indexes is then performed to provide an intermediate set of proposed indexes. Indexes having most benefit based on storage constraints are then selected. The optimizer is then ...

A file format for a serverless distributed file system is composed of two parts: a primary data stream and a metadata stream. The data stream contains a file that is divided into multiple blocks. Each block is encrypted using a hash of the block as the encryption key. The metadata stream contains a header, a structure for indexing the encrypted blocks in the primary data stream, and some user information. The indexing structure defines leaf nodes for each of the blocks. Each leaf node consists o...

An exclusive encryption system is established using multiple computing devices. The exclusive encryption system allows for the exclusion of certain plaintext (e.g., by one of the computing devices) and ciphertext (e.g., by another of the computing devices) while at the same time maintaining the privacy created by the encryption (e.g., so the other computing device cannot see the plaintext). The exclusive encryption system may be implemented as part of a serverless distributed file system with di...
