I have recently started learning Ruby and Perl. Could any of you please suggest me compilers for those, so that I can practice?

For Perl you want Strawberry Perl or DWIM Perl. Strawberry probably has everything you want but DWIM is just Strawberry with some extra modules and the Padre ide:
It contains:
Strawberry Perl 5.14.2.1 RC which itself is a standard Perl with several extensions already installed.
A large part of Task::Kensho, a list of recommended packages.
Padre, the Perl IDE 0.94.
Module::Version 0.12 so you can use mversion to check which version of each module you have.
Moose 2.0402, the post modern Object System.
Dancer 1.3092 to build a light-weight web application.
Plack and plackup 0.9985 to serve your web pages.
Perl::Critic 1.117, to police yourself.
Perl::Tidy 20101217, to keep your code nice.
DateTime 0.72 to make it easy to deal with dates and time.
SQLite 1.35, to hold your data tight.
MySQL 4.020, PostgreSQL 2.18.1 and DBD::ODBC 1.31 drivers.
Lots of additional modules... (see details in the README file.)

I have searched the web and the Swift documentation,
but so far have not found a way to execute a ruby script.
Is there a way to do this? I am assuming the script
exists as a file on the system.
Using system worked for me. The following calculates 5 factorial in Ruby under Swift:
import Cocoa
let value = 5
system("ruby -e \"p (1..\(value)).inject{|a,b| a*b}\"")
This use to be possible in Objective-C through MacRuby, but It didn't offer much benefit over the other options unless you need to interact very heavily between the two environments. MacRuby is more for interacting with the Objective-C world from Ruby than vice-versa, but it does allow you to freely mix the two languages in your project.
Sadly, MacRuby has effectively been dead in the water for a couple of years now. It had a lot of promise, but it didn't have the necessary internal support at Apple for it to succeed.

I found the code completion of Xcode is much convenient,but how to make it for vim?
Any plugins support or how config the vim file?
Vim supports some kinds of completion out of the box: :help ins-completion.
There are several packages that expand this system, most well-known among them being YouCompleteMe and NeoComplete/NeoComplCache.
There are specialised solutions for individual languages, such as eclim for Java (which connects to an Eclipse server, and thus can actually understand Java and provide many IDE features).
But ultimately, as romainl says, Vim is an editor, not an IDE, and if you're trying to use it as an IDE, expect pain.

I read the article below and would like to try scribble in Ruby but the only source i can find is on svn which i don't have or use.
Here is the link
http://nex-3.com/posts/3-scribble
Is this a gem and how can i install it ? Does it run on Ruby193/Windows7 ?
Please share your experience.
The page you linked says:
You can download and run Scribble right now from it’s Subversiony home. This home is currently on Hampton Catlin’s server, because mine doesn’t support Subversion.
svn co svn://hamptoncatlin.com/scribble/trunk scribble
To run it, just run the bin/scribble file. It requires Ruby, of course, as well as the latest Ruby GTK+ bindings and Ruby Cairo bindings (and of course GTK and Cairo themselves). Note that this won’t work with the latest RubyGems – you actually need to compile the latest development versions of these yourself. If you’ve got all of those, it should be able to run on OSX, Linux, and Windows.
Unfortunately, though, the SVN server seems to have disappeared sometime around 2010. There seems to be a fork of the code at https://code.launchpad.net/~vcs-imports/scribble/trunk , but i haven't even looked at the code, much less tried to use it. You'll likely need a Bazaar client (bzr) to get it...at which point the rest of the instructions would apply.

Does anyone know an easy to use application that creates exe setup installation package for any windows program? InstallJammer looks a good candidate but its development is discontinued and it does not create a desktop icon although I configured it to do so (probably a bug - googling did not help much). Any comment would be appreciated. Thanks.
All a question of how complicated you want to get. If you just need something quick to install a handful of files, I would recommend NSIS. If you need something with a bit more power and flexibility I'd go with WiX, which emits Windows Installer MSI packages.
Both of these a script\text based, so you can see what you are doing, and don't have any license fees.
I second the recommendation for NSIS. It will do everything you need, works with XP, Vista and Windows 7. Is compatible with 64-bit and handles user privileges and short-cuts.
It is all I use for all of my installers and patches and some of them are quite complex, it is also free and open-source.
Download the main framework at http://nsis.sourceforge.net/Download and then I would also recommend using the HM-NSIS editor for writing your scripts http://hmne.sourceforge.net/

I'm looking for a nice software to store tickets information locally. It should work only on my laptop under Linux, and be easily installed. The core features that I need:
storing tickets
allows to create additional documentation
don't take too much ram
very easy installation (I don't have whole days for configuring)
multiproject
You can try Project Kaiser
I use redmine and it's fantastic for all of the above. It's browser based so you'd need to install and configure it but it's not hard and well worth the effort.
Redmine is quick efficient and it's the best tool of its kind that I've ever found and I've looked tried many.
I know little about ruby/rails and it took me a few hours to install from clean using the guides.
How about a TidliDu http://www.giffmex.org/tiddlydu2.html. You can't make it easier to install. Create a new one for each project.
OpenOffice spreadsheet?
