ActiveRecord provides a convenient interface for serializing Ruby objects. In the model file, simply declare which column will store the object:

Today I asked this question on StackOverflow:
My development team of four people has been facing this issue for some time now:

However, sometimes we need to run operations on the [...]

We have some exciting things in the works and as a result, will be moving to Europe later this summer to continue developing our product and business. We can’t yet share all of the details on why we’re making the move, [...]
Up until now, I’ve done nearly all of my Rails programming on Windows Vista (64 bit). The environment has been pretty good, but it’s time for a change. This was probably due a while ago, but I’ve decided to explore Linux with a dual boot of Ubuntu 10.x.
