Yes. > 2- Is there a big difference between 1.8 and 1.9? Yes, especially under the hood. But language changes aren't so dramatic IMHO. Typically stdlib functionality was extended so old code should run OK most of the time. > 3- Will code written in 1.8 works in 1.9? Actually much code will work unchanged but you need to test this of course. > 4- Can someone show me how to install the newsiest version? I typically do $ ./configure --prefix=/usr/local --program-suffix=19 $ make $ make install Then I can start ruby19 and irb19, ri19 and it won't interfere with old versions. Not sure how you would go about this on a Mac though. > 5- Do I need to uninstall 1.8 first? No. > 6- Why is that I cannot see the Ruby installation anywhere in my Mac, > where is Ruby installed? Sorry, no Mac knowledge here. Cheers robert -- remember.guy do |as, often| as.you_can - without end http://blog.rubybestpractices.com/
