BTC Price

What does it do?

From within your Code (or really any) directory, run:

git clone git@github.com:mecampbellsoup/btc_price.git;

then:

cd btc_price.

If you do not have the memcached gem, go get it:

gem install memcached.

Next, start (and immediately background) your cache process with:

memcached -p 11211 &;

and finally you can run the gem's executable:

btc_price.

You should see some content in STDOUT like this:

External services status: Good.
Current BTC price: $622.21.

If you run the executable again (btc_price), you'll notice it's much faster. This is because the library uses memcached to cache the BTC price and avoid making redundant API requests.

Why did I write this library?

I wrote this small library initially to learn about caching and how to implement it in Ruby.

We started using a text file for caching and later on switched to Memcached.

I like to hack on this on the weekends in order to improve my OOP and design skills.
