I'm almost done with Ruby but now want to try my hands on Ruboto, ruby on android.
Google failed to give me sufficient (almost no results).So can anyone please share some tutorials on Ruboto.
From the looks of it, Ruboto's own documentation is still under development! Ruboto's GitHub Wiki provides some tutorials and examples, but they're not totally complete. However, this may be enough to get you started. Be sure to read the README (which is also available on their GitHub Wiki):
https://github.com/ruboto/ruboto/blob/master/README.md
That should get you set up to go through their own tutorials:
https://github.com/ruboto/ruboto/wiki/Tutorials-and-examples
As Ivaylo Strandjev has already said, what you'll really need to learn to make apps with Ruboto is a sufficient knowledge of Ruby. From there, Ruboto is simply extending Ruby's capabilities to communicate with Android. Understanding how it does so is all you need!
You're right, though! There aren't a lot of tutorials, yet, because Ruboto is still a very early effort. Provided you have a good knowledge of Ruby, however, these tutorials and a thorough reading of Ruboto's documentation on GitHub should be more than enough to get your feet wet.
Happy Rubying!
Ruboto now supports a lot of ruby's functionality and also there are some examples included on how to do "more fancy stuff". Still so far all the programs I have written in ruby work on ruboto too. So my suggestion is - find a ruby tutorial instead.

Is there any alive Haskell library which implements FRP and could be used to program UI/interactive graphics?
What I expect from such a library:
Doesn't use any crazy GHC extension, so code could be understood by mortals.
Not abandoned (had some commits in last 6 mouths and few answered thread in mailing lists).
Backed by some modern window library (Qt, GTK) and covers fair amount of it functionality.
Also has drawing and animation support, i.e. let the user to simply define some shapes and effects and bind their parameters to behaviors.
I checked some resources and picture is quite sad.
Original Fran and its ancestor Fruit family are officially dead.
Reactive is an abstract framework and doesn't have bindings to real UI/graphics (did I miss something?).
Netwire also look aimed for general case. Currently it has no documentation covering how to build UI/graphics with it. The only example is a full application not even close to tutorial.
Grapefruit looks good, but it had last commits in December 2013 and the mailing list full of spam. I consider it abandoned.
Yampa has not documentation at all, and the mailing list is silent since November 2013.
Reactive Banana has been updated relatively regularly, has bindings to SDL, some decent examples, a tutorial and a relatively small but decently commented API reference.
There's also a backend to wx, and see this question about using it with GtK.
The maintainer, Heinrich Apfelmus, is on Stack Overflow, and often answers questions on the reactive-banana tag.
Does this suit your needs?
GUI programming is the major use case of reactive-banana I believe.

For designing the MEAN stack application, I am creating separate modules( angularjs,expressjs,nodejs,mongodb) and i am linking them manually. Can you please suggest me an IDE available for directly designing MEAN stack application.
These topics on Stack Overflow usually get flagged as contentious or something after a while. However I thought I would share my own experience of using JavaScript IDEs under Windows.
I was using PyCharm, however my dev box is ageing a bit and PyCharm is too heavy for it. Besides, as the name implies, it's really for Python, in fact I started using it for Django.
If I could afford WebStorm and a box to run it on, I'd definitely check that out :)
I fell back on the default at my workplace, Notepad++. However the linter add-on is a bit clunky, and it has real difficulty rendering JavaScript in HTML.
For now I am satisfied with my recent discovery of brackets.io. It does have an early days feel to it, but I find it's code completion particularly useful, and once I got an add-on to use JSHint instead of JSLint it chimes very well with the meanjs code I'm learning from. Meanjs uses swig templating, which parses as straight HTML so there's no problem there, but if you're wedded to a particular template module then you should look for an IDE that supports it, either directly or via add-ons. Brackets.io seems to have quite a lively add-on community at the moment.

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?

I'm planning to perhaps purchase an android phone, and would love to be able to script some simple apps in Ruby on it. I found this article from back in August where the author was able to get the scripts working, but since I'm not a Java head, I had a hard time understanding all the steps.
http://amazing-development.com/archives/2009/08/04/android-scripting-environment-supports-jruby/
Do you know of any other tutorials or how to's out there that explain the process in more detail? Do you know if performance has improved since August?
There is a nice implementation of an Android app (irb in fact) based on JRuby in headius's repository on github. He has some details within the readme on how to use it and the source gives a good example of how to implement anything further.
There is a simpler app (think to "Hello world") but shifting to Mirah (formerly Duby) as opposed to JRuby. I know it's not exactly the same, but you get much the same coding experience but significantly more performance.

I searched a lot on this but haven't yet got any standard or rather systematic guide for Win32Ole in Ruby. Ruby on windows by David is very good but I need a complete, systematic standard tutorial for WIN32OLE ruby APIs.
Please suggest!
Thanks
Pradyumna
I fear you may not find one. David Mullet is working on a book but that rather implies that it's still some considerable time away from publication.
I need a complete, systematic standard
tutorial for WIN32OLE ruby APIs.
How "complete", "systematic" and "standard" do you really need it to be? You have to consider that someone needs to have the motivation to produce such a tutorial, which would be a substantial piece of work to undertake for no reward; that's why a book is in preparation - then we can pay David for his expertise!
So we may need to modify your need to be more satisfiable by current reality: are there particular problem(s) you are trying to solve? Could you put some more specific questions here?
I was thinking about posting the same question when I came across your post. I'm not sure what exactly you are trying to do, but I have had some success with Ruby and Excel. I find that if you can create an Excel macro that does something similar to what you would like Ruby to do, you can more or less 'rubyfy' the macro code and access all the same methods and attributes in your Ruby code. I was able to figure out how to get Ruby to create Excel graphs, and cell color coding this way. If the software you want to interact with has a similar macroing tool, you may be able to work out how to use ruby to interact with that software. I do look forward to the book that Mike mentioned.
Assuming that the problems are with win32OLE rather than with ruby, I'd be half tempted to look for guides in other scripting languages, such as perl.
