Could you tell me, in very plain words please, whether once I have created my contract code and "sent" it to the Ethereum network, I can update it? or do I have to write a new program and send it to the network (the oldest one then "dying" out of gas).
PS: the following extract (with a talk about update) is from "https://github.com/iurimatias/embark-framework
": Automatically deploy contracts and make them available in your JS code. Embark watches for changes, and if you update a contract, Embark will automatically redeploy the contracts (if needed) and the dapp.
