Ruby on Rails Wednesday, June 30, 2010

Hi :)

confused again:
My first question here is a bit less connected to the original post's
subject, so @Jeremy - I apologise..

@Marnen: Just read this again:

After reading your reply, I thought I should give it a try to
Passenger, but according to this I should be using VM while I just
understood from the previous answer I do not have to (as I wrote
before, will move to VM gladly, but just trying to understand first)

Also another question about Heroku -
being a host, I was wondering why would it guide me to point my DNS
server to Heroku, Zerigo being recommended?
Do I need to purchase separately a DNS service when deploying to
Or is it again my lack of understading of an additional functionality?

(was looking on this page here:

Thanks again :)
