I'm new to Bitcoin. I installed and ran the GUI app, checked "Generate Coins" in the Settings menu, and the status bar reads "Generating". How do I know if it's actually working?
I'm aware that mining is a CPU-intensive process that could take a long time; this is why I'm skeptical that the app is working.
top reveals that bitcoin is only using about 25% CPU. I haven't limited CPU use in the Preferences.
I've read the mining guide on weusecoins.com. It says I must setup JSON-RPC, but it's ambiguous about how to do that. Do I need to set a username/password in the config file that it points to on the wiki? If so, how do I create a username?
I'm running on Mac OS X and Bitcoin 0.3.21-beta, the latest at the time of this post.
