An efficient binary translator uses peephole translation rules to directly translate executable code from one instruction set to another. In a preferred embodiment, the translation rules are generated using superoptimization techniques that enable the translator to automatically learn translation rules for translating code from the source to target instruction set architecture.

Methods and related systems for indexing the contents of documents for comparison with the contents of other documents to identify matching content. A method for comparing the contents of a query document to the content on the World Wide Web is set forth. The contents of a query document are indexed and compared to content from the World Wide Web which is continuously retrieved and indexed. The method for indexing may comprise selecting substrings from the document, hashing the substrings to generate a plurality of hash values having a known range of values, selecting certain hash values to save from the generated hash values, and sorting the saved hash values. Methods for selecting certain hash values to save are set forth.
