Rails Hosting Questions

Hi everyone,

I use Hostgator as my hosting provider and I checked out the versions of
the apps they are running:

Linux CentOS: 5.3
Ruby: 1.8.5
Rails: 2.3.2
MySQL: 5.1.30

I've been programming on a windows box but I do have a virtual linux box
setup (not for this particular model) - I wasn't even aware that people
still used Ruby 1.8.5..

My current platform for development is:

Windows Vista 32
Ruby: 1.9.1-p129
Rails: 2.3.2
MySQL: 5.1.30

Do you think that there will be some problems with my development
platform when it goes over to production?

I'm always a fan of having a development setup that is as close as
possible to the production setup. There are plenty of differences in
the ruby standard library, behavior of the language and even syntax
between 1.9 and 1.8
