[Ethereum] what is the difference between payable and view in a smart contract in solidity

An IDE is an integrated development environment.

That is a programming environment integrated into a software application that provides:

• GUI builder
• text or code editor
• compiler and/or interpreter
• debugger

The Mix DApp IDE and the Solidity Browser are all examples of IDEs. They may differ in features and completeness of implementation.

The advantage of decentralization is that you can use the browser-based solidity compiler which works on top of your ethereum node. Except for the node, no additional software has to be installed.

Transaction costs are the costs for sending the contract code to the ethereum blockchain, they depend on the size of the contract.

Check out the source code:

 var getGasUsedOutput = function (result, vmResult) {
        var $gasUsed = $('<div class="gasUsed">');
        var caveat = lookupOnly ? '<em>(<span class="caveat" title="Cost only applies when called by a contract">caveat</span>)</em>' : '';
        if (result.gasUsed) {
            var gas = result.gasUsed.toString(10);
            $gasUsed.html('<strong>Transaction cost:</strong> ' + gas + ' gas. ' + caveat);
        }
        if (vmResult.gasUsed) {
            var $callGasUsed = $('<div class="gasUsed">');
            var gas = vmResult.gasUsed.toString(10);
            $callGasUsed.append('<strong>Execution cost:</strong> ' + gas + ' gas.');
            $gasUsed.append($callGasUsed);
        }
        return $gasUsed;
    };

Execution costs should be really the vm execution costs, if I interprete the parameter vmResult correctly. Is this maybe because a default constructor will be called any way?
