Operating Ropsten Ethereum testnet network with Geth and Mist on OSX

Operating Ropsten Ethereum testnet

from a newbie to newbies


I believe that a development environment is one of the access key in learning new technologies. I didn't find on the internet a simple and common path to make the Ropsten network, the Ethereum public testnet, work.

So I'm writing down a couple of command lines and links that can be useful to achieve it.

Remap Caps Lock to Control on Windows 10

Ways to remap caps lock to control on Windows 10

These methods in this gist worked for me on my U.S.-based keyboard layouts. I am unsure about other layouts. If you have problems, revert your changes; delete the registry key you created (and reboot).

Update: you should probably scroll down to approach 4 where I suggest using Microsoft PowerToys Keyboard Manager.

Approach 1. Manually through regedit

Navigate to and create a new binary value in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout named Scancode Map.

How to install Meld on Windows and getting it set up with Git

Install Meld from their webpage

I had to tell git where it was:

git config --global merge.tool meld git config --global diff.tool meld

If using windows 8 and 10 use the following git config --global mergetool.meld.path "/c/Program Files (x86)/meld/meld.exe" git config --global difftool.meld.path "/c/Program Files (x86)/meld/meld.exe"
