It's quite common to open up a pull request on GitHub and be confronted with the message This branch has conflicts that must be resolved. This situation arises when you create a feature branch on an older commit from the master branch. Maybe you forgot to run git pull master before git checkout -b geocoding_vignette or maybe a collaborator changed some of the same files on GitHub while you've been working on new things. There are many ways to fix this. One is using the Web Editor build into GitHub and fixing conflicts by hand. This works great if there are not too many conflicts.

Another technique is to rebase your pull request onto the master branch (Move your additional commits on top of the most recent master commit). This is conceptually clean, but sometimes confusing in practice to do cleanly. This example walks through the process where you want to do a rebase, and resolve conflicts by overwriting whatever is on the master branch with change

Since the Byzantium fork, Ethereum provides with a way to know if a transaction succeeded by checking its receipt status. A receipt status can have a value of 0 or 1 which translate into:

• 0 transaction has failed (for whatever reason)

• 1 transaction was succesful.

The purpose of this sample is to estimate the gas cost of a simple transaction and modify the assigned values of gas and gasprice.

Gas is the pricing system used for running a transaction or contract in Ethereum. The gas system is not very different from the use of kW-h for measuring electricity home use. One difference from actual energy market is that the originator of the transaction sets the price of gas, which the miner can accept or not, this causes an emergence of a market around gas.
