All below stuff run in PRODUCTION rails environment, make sure production settings in your database.yml points to a test database!!!
###Reset database
RAILS_ENV=production rake db:reset
###Start matching engine
# modify config/amqp.yml first if rabbitmq server is running on node other than 127.0.0.1
RAILS_ENV=production rake daemon:matching:start

#IRC#
As-of version 0.6.x of the Bitcoin client, IRC bootstrapping is no longer enabled by default. The information below is accurate for most versions prior.
Bitcoin joins a random channel between #bitcoin00 and #bitcoin99 on irc.lfnet.org. Your nick is set to an encoded form of your IP address. By decoding all the nicks of all users on the channel, you get a list of all IP addresses currently connected to Bitcoin.
For hosts that cannot make outbound connections on port 6667, the lfnet servers are also listening on port 7777.

The more Virtus code I wrote, the more awkward I feel it is. It's not because Virtus is inherently bad, I just don't think it fits our case.
So many attributes need to be marked reader: :private. It's not ruby's way. Ruby has its own private keyword.
NilToDefault is bad. How do I decide whether a model need to include it? Or we simply include it everywhere?
The difference between writer_class and default is subtle. Why does the implementer add a new writer_class here? Why does he use default value there? We're using different ways to do the same thing (compute values) here.
writer_class is awkward. Why do I need to create a class just for its coerce method? I feel like writing Java.

#define_method will create a closure, without careful use it could cause memory leak, as pointed out here.
OpenStruct use #define_method to create accessors dynamically, we suspect that will cause memory leak.
So I create two scripts to prove it, however the result shows the opposite: OpenStruct doesn't leak memory.
