Abstract: An application error detection platform computer processor may monitor execution of an application for a customer and determine that an application error has occurred. Responsive to the determination that an application error has occurred, an error fingerprint creation platform computer processor may access a stack trace representing execution of the application when the application error occurred. An error fingerprint associated with the occurrence of the application error may then be determined by applying a hash function (e.g., SHA-1) to information contained in the stack trace. Electronic records including an indication of the error fingerprint may then be received by and stored in an application error log data store. The application error log data store may then be searched for duplicate error fingerprints to facilitate application error resolution.

Abstract: According to some embodiments, an application error detection platform computer processor may monitor execution of an application for a customer and determine that an application error has occurred. Responsive to the determination that an application error has occurred, an error fingerprint creation platform computer processor may access a stack trace representing execution of the application when the application error occurred. An error fingerprint associated with the occurrence of the application error may then be determined by applying a hash function (e.g., SHA-1) to information contained in the stack trace. Electronic records including an indication of the error fingerprint may then be received by and stored in an application error log data store. The application error log data store may then be searched for duplicate error fingerprints to facilitate application error resolution.

Abstract: A process to prepare an olefin from its corresponding alcohol is improved by reacting, under reaction conditions including a first temperature, an aliphatic alcohol and, optionally, diluent water, to form a reaction product including at least a dialkyl ether. The product is then reacted again, under higher temperature to complete the dehydration of the dialkyl ether to the desired olefin. This process is particularly suitable to prepare ethene from ethyl alcohol. The stepped temperature scheme serves to reduce the formation of byproduct aldehydes, which in turn reduces coke formation, fouling, and the need to handle large amounts of water, thereby lowering energy and capital costs.

Abstract: A process for preparing polymeric compositions having low permeability to gases and which are particularly useful in the packaging industry wherein said polymers are prepared from rubber-modified copolymers of an olefinically unsaturated nitrile monomer and a vinyl aromatic monomer using tertiary butyl mercaptan as a chain transfer agent in the polymerization reaction.
