Is it possible to integrate MS Outlook/Exchange tasks with Rails? I know how to send emails with Rails, but that isn't using anything "special" about exchange, just pointing it at the server. What is "special" about an Outlook Task and how I can I create/read/update/delete them from Rails. (Even a subset of CRUD would be great.) PS. I ...

Here is one more newbie question: require 'tasks/rails' I saw this line in Rakefile in the root path of every rails project. I guess this line is used to require vendor/rails/railties/lib/tasks/rails.rb to get all rake tasks loaded: $VERBOSE = nil # Load Rails rakefile extensions Dir["#{File.dirname(__FILE__)}/*.rake"].each { |ext| l...

I've been a dev using rails since it's initial release and have recently lost touch with it because I've done a lot of work with Django due to my recent fondness of python. I do like Ruby as well and was asked by a friend recently if he should approach Rails or Django. Given that Rails is merging with merb and has a huge user-base versus...
I extracted simple example: require 'pp' x = 1..3 pp x.map do |i| {:value => i, :double => (i*2)} end pp x.map { |i| {:value => i, :double => (i*2)} } pp(x.map do |i| {:value => i, :double => (i*2)} end) pp(x.map { |i| {:value => i, :double => (i*2)} }) I am wondering why first pp produces: [1, 2, 3] While all the oders are giving...
