It seems that Red Hat doesn't include software that is made by a company. OpenVPN and MongoDB come to mind. Perl and Python are in RHEL/CentOS. What could be a reason Ruby isn't in RHEL?
Update
RedHat have now announced Red Hat Software Collections 1.0 which exactly addresses this need.
I don't use distribution rubies. It is best to compile them from the latest version or whatever version you use, those packages in the distro repositories are frequently outdated.
Check out RVM or RBENV. I guess why they are not could be interesting, but probably not a question StackOverflow at large is going to like.

I have started working on joomla and i want to know which Extensions i should install while using Joomla platform except the default installed extensions in the package.
If I understand your question right you don't have to install anything at all to start working in joomla. You can start blogging or component development or whatever task you are supposed to.
It really depends on the purpose of your website. If you check this link you might find some important extensions which might help you out.

I just updated my Xcode from 4.4 to 4.4.1, but I can't seem to find what changes they have made to Xcode. Could anyone please enlighten me? I can only find the changes for 4.4.
This is new in xcode 4.4;
https://developer.apple.com/library/ios/#documentation/DeveloperTools/Conceptual/WhatsNewXcode/Articles/xcode_4_4.html#//apple_ref/doc/uid/TP40011649-SW1
I think 4.4.1 is just a small fix of a very small issue, nothing big!

Xcode is available from the Apple's developer support center. You'll need an account but they are free.
