I'm looking to expand my ruby knowledge beyond scripting, test code and file parsers by writing some web services. I'm thinking of using sequel as an ORM. What advantages are there to using Sequel Core or Sequel Model? What should I be looking out for? What rules of thumb are there for picking one or the other? ...
Is it possible in ruby/rails to order a result set after doing a find?

Basically there is a file in the initializer folder that loads the extension from the lib directory. In my initializers folder I have a file with this: require 'amaz...
I've read that Ruby 1.9 is a lot faster than 1.8, however it seems like it hasn't become the standard in the Rails community yet. What are the pros and cons of using Ruby 1.9 for new apps?

Does Rails 2.3 support a file-based session store out of the box any more? It looks as though it supports only use of active_record_store and mem_cache_store, in addition to the default cookie-based.
