Adam Wiggins just posted a few paragraphs by Tim Lind from his article titled Innovation in Database Technology. Rarely do I just post direct quotes here, but I really thought the paragraphs were insightful, so I’ll share them for those that haven’t had the pleasure yet.

Adam McCrea of EdgeCase has put together a screencast demonstrating how to easily implement Ajax file uploads in your Rails application. It's about ten minutes long.

I had a really great time at RailsConf. I met a ton of really cool people bursting with enthusiasm for great projects. I sort of knew this already, but now I know it viscerally: the diversity of things that people are doing with Rails far outstrips the ability of those most deeply involved in building it day-to-day to anticipate. What was also really great was that so many of the ideas people asked me about could be answered by pointing at new extension points or modular APIs that we’re adding to Rails.

Short & Sweet:
Each_with_object is the same thing as inject, except you don’t have to return the object at the end of the block you pass. Since most of the time you are using inject, you have to return the hash or array as the last line in the block, using each with object will let you do the same thing, but with less code.
