I’ve been listening to David
Heinemeier Hansson talk on the "Ruby on Rails" project
(download the talk here). I really like
his summary of Ruby slide which he calls "Ruby in five
E’s".
I’ll reproduce his summary here:
- Everything is an object
5.times do print "hello world".capitalize end
- Elegant blocks gives inline power
db.select_all(sql).inject([]) do |objects, row|
objects << instantiate(row)
end
- Exploring with reflection
- Extending at runtime (even standard lib!)
- Extensive standard library
- XML, Test/Unit, Distributed Ruby, XML-RPC, WEBrick
