So, you are reading everywhere that Ruby 1.9 is faster than 1.8 (even I say so! :D ) and you want to give it a try or even port your existing code to it. Where should you start from? Here's a collection of links to posts, pages, discussions, etc with useful information.
First of all, here is a video talk from Matz for Google Tech Talks:
- Ruby 1.9, by Yukihiro Matz Matsumoto
Also, some presentations:
- Matz on Ruby 1.9 from his Rubyconf 2007 talk.
- Migrating to Ruby 1.9, by Bruce Williams from his Scotland on Rails and Austin on Rails talks.
- Wild & Weird Ideas: An overview of Ruby 1.9, by Hlame from his LRUG presentation.
Blog posts covering multiple differencies between the two versions of Ruby:
- Getting Code Ready for Ruby 1.9, by James Edward Gray II.
- On The Horizon : Ten Things I like about Ruby 1.9, by Gregory Brown.
And after you've finished reading all the above and want an almost complete listing of changes (!!!) you can find it on this post from eigenclass. Have fun :)
And now, you also want some info on how to get Ruby 1.9 side-by-side with the good-old 1.8? Ok, here are some links for you too:
- Installing Ruby on GNU/Linux(Gentoo, (K)Ubuntu, Fedora, SUSE) And MS Windows.
- Installing Ruby 1.9 on Mac OSX, by Mikel Lindsaar.
- Installing 1.9, by Chris (NOTE: I used this one to install Ruby 1.9 alongside 1.8 under Mac OS X, since I already have the readline libraries installed from MacPorts I think).
