Abstract: Disclosed is a method and system for modifying content stored in a blockchain. The method comprises identifying an old block of the blockchain comprising undesired data in a transaction of the old block. An updated block may be created by correcting the transaction of the old block. A new block hash may be determined for the updated block. Corrected form of the transaction may be submitted, as a new transaction, along with the new block hash and the difference between the new block hash and hash of the old block. Miners may be allowed to mine the corrected form of the transaction, along with other new transactions. The other new transactions may be mined, based on a consensus of users of the blockchain, into a new block connected to a tip of the blockchain, and the old block may be edited to introduce the corrected form of the transaction.

Abstract: Disclosed is a method and system for debugging source code of an application. The method includes establishing a WebSocket connection with a Chrome DevTools Protocol, using a unique Uniform Resource Locator (URL) created by Node.js. The Chrome DevTools Protocol is a V8 inspector. The method further includes listening for asynchronous messages from the V8 inspector. The asynchronous messages are defined by V8 inspector protocol. Responses received from the V8 inspector protocol are processed and debugger operations selected by a user are translated into operations known to the V8 inspector. The source code of the application is executed on the Node.js utilizing launch configuration and data required for starting a Node.js process with responsibilities of terminating the Node.js process when the user ends the debug session.

Abstract: The invention discloses an improved process for the preparation of 2,2,5,5-tetrasubstituted hexane-1,6-dicarbonyl compounds, and in particular diethyl 2,2,5,5-tetramethylhexanedioate and dimethyl 2,2,5,5-tetramethylhexanedioate, by the alkylation of 1,2-difunctional ethane compounds with enolates of carbonyl compounds. The process provides higher yields and greater synthetic brevity than existing processes.

Abstract: An artificial surface for the growing of turf forming grasses and other plants, comprising a mixture of rubber, a polymer modified bitumen emulsion and slow release, plant nutrient containing particles, mixed in sufficient proportions and to a substantially even distribution of each of the rubber, emulsion and particles throughout the mixture so that, when laid and cured, the mixture uniformly produces a water permeable, heat conductive surface having air pockets through which a root system of the turf forming grasses and other plants can penetrate, the plant nutrient containing particles being trapped within the surface for slow release of plant nutrient to the root system.
