Abstract: A method comprising: stopping to use one or more first approximate membership filters for servicing of read requests that are incoming to a storage system; increasing a size of a set of first data structures that are available in the storage system, each of the first data structures being used by the storage system for write request amortization; replacing the one or more first approximate membership filters with one or more second approximate membership filters, and building each of the one or more second approximate membership filters by: freezing all non-empty first data structures in the set, and copying respective contents of each of the frozen non-empty first data structures into any of the one or more second approximate membership filters; and starting to use the one or more second approximate membership filters for servicing of read requests that are incoming to the storage system.

Abstract: Described are techniques for generating a parser. A graphical representation of a finite state machine is provided for determining whether an input is syntactically valid in accordance with a syntax represented by the graphical representation. A second representation is generated which corresponds to the graphical representation. Using the second representation, a parser is generated for parsing an input. The parser determines whether the input is syntactically valid in accordance with the syntax.

Abstract: An improved technique involves providing a decision procedure to determine whether an unsolved customer problem goes to a public problem-solving forum or internal support. For example, when a support center receives a customer problem and determines that the problem does not have a known solution, it assigns a severity weight to the problem based on a description of the problem. Along these lines, suppose that the call center receives a customer problem regarding excessive down time. When the call center places the problem into a “downtime” classification, the call center counts how many other unsolved “downtime” problems are awaiting solution. If there are not many similar problems awaiting solution, then the call center assigns a high severity level and assigns the task of solving the problem to a public forum, such as a crowdsourcing application.

Abstract: A method is used in managing quality testing. Quality tests are mapped to characteristics of a product under test. Based on the mapping and a result of a previously executed quality test, a respective relevance level is determined for each of the quality tests. Based on the relevance levels, a priority is determined among the quality tests.

Abstract: Described are techniques for obtaining grammar updates. A grammar service receives a notification regarding a grammar update applied to a target. The grammar update is an update to a command syntax used by said target. The grammar service sends an update request to said target to obtain said grammar update. The target sends to the grammar service an update response including said grammar update. Also described are techniques for processing a command line. One of a plurality of rule sets is selected. The command line is parsed at said client using said selected rule set. If parsing did not result in a syntax error, a command request is sent from said client to said target. In response, the client receives a command response including information regarding a version of syntax rules currently used on said target.
