Recently my company asked me to gather knowledge in EXTJS. I have seen a lot of examples from Sencha
But, when I want to develop applications using extjs what should i do? Now I want to dive into building application using ExtJS. Please give me some link.
There's definitely a bit of a learning curve with Ext, but the best place to start really is their MVC application tutorial and just reading the application documentation:
Tutorials:
Ext MVC Intro
App Architecture pt 1
App Architecture pt 2
App Architecture pt 3
Documentation:
App documentation
In addition, I would make sure to get an understanding of how the event system works in extjs as it is the core of how wiring the components together works. Have a look at the base observable class to get some detailed information - all the components that can fire events inherit this class. Generally speaking, the documentation is your friend in Ext though.
One thing I did while learning ext was read over Jay Garcia's book ExtJS In Action. By no means will it teach you everything you need to know, but it gives a good overview of what Ext is capable of and some common usage patterns.

I want to develop a socket based chatting app in Titanium compatible with Android, iPhone and Blackberry.
Please give me suggestion about it
If you want a "socket based chatting app", then you've already made decisions about the implementation, and so you really just need to know the interface for implementing it. Try reading the fantastic manual, it is very detailed on how to use sockets.
http://docs.appcelerator.com/titanium/3.0/#!/api/Titanium.Network.Socket.TCP
You'll need to roll your own server side to accept the socket connections, and your own protocol for the communications. Or adhere to an existing protocol.
Or you can use the existing, working Ti.Cloud sample I created. It is the Titanium specific version of what Hini linked at nodeacs.cloud.appcelerator.com --
https://github.com/appcelerator-modules/ti.cloud/tree/master/commonjs/example/windows/chats
You can use Titanium along with Node ACS to create the application.
Here is a sample chat application tutorial. I hope it helps you.

I have a project that's in the design phase and looking at my options have decided on using Postgresql for the application backend because of licensing and features. I have searched around but I am unable to find any solid information on using Postgresql in Xcode or even with OSX applications. Could someone point me in the right direction any help would be greatly appreciated.
You have not given quite a lot of context.
On the application side there are quite a few pieces of software running under OS X that interface with PostgreSQL, for example the standard GUI pgAdmin.
But I believe you're more concerned about the developers perspective. Probably the most common way is to use the libpq library that comes with PostgreSQL. It is well documented and rather stable. Integration into your software project should be straightforward.
If you are looking for an Objective-C framework, you could try out BaseTen. Never used that one, though.
If you want more specific help, you have to ask more specific questions.

I have recently started developing iPhone apps without any prior theoretical knowledge about iOS or Objective-C, could someone tell where should i start reading about objective C ?
An excellent starting point is the Apple documentation. There are some good books around, too.
After grasping the language constructs, your next stop for more specific information about any iOS controls, concepts and techniques, can be the iOS Developer Library, which is full of guides, references and FAQs.
My favorite site is given below, It includes most of the tutorials and stuff. Hope that helps you. Also you can start with guide from apple
http://www.raywenderlich.com/tutorials
http://www.codeproject.com/Articles/88929/Getting-Started-with-iPhone-and-iOS-Development
I recommend the following link
http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/ObjectiveC/Introduction/introObjectiveC.html
You can also use Objective-c tutorial by lynda.com

What is the meaning of it?
What is Core Data?
What is so special about it?
When I went to create a navigation based application it has a check box for Core Data.
If I use this option then what will it work well for my project?
Also, when i choose View Controller Based Application while creating a new project the Core Data check box is not available. Why is this?
sure, sqlite is a lib for db too, and core data is an object-c lib for database... both are a good way to manage db, you have just to choose your favorite one...
and this may help you:
http://tapity.com/iphone-app-development/readwrite-data-on-the-iphone-property-lists-sqlite-or-core-data/
Those are broad questions better answered by Apple's documentation.
Core Data is a persistant store of your object graph, It can be backed by sqllite, but doesn't have to be.
if you are unsure how you want to store data, CD is a good choice, it is very well optimised. as a rule you only want to use something other than core data if you have a very good reason.
read the apple docs for a better overview, and there is a fantastic book by Marcus Zarra. If you are going to be developing for iOS it is well worth learning about, even if you choose not to use it.
with regards to why it isn't available in the VC based application, there is no reason not to use it with a View controller based app, but you would have to type the code to implement it, there isn't a default design pattern from apple for it in the templates, so you would have to decide how to impliment it best for your use case.

Do you know any book, blog, tutorial which explains in a detailed way the use of some open source projects? Maybe you have written such a tutorial, example of open source libraries, and your final product is great for a beginner to understand it.
I'm in the learning stage of OOP and I really need to learn by examples. I'll like to find some text which explains the use of some open source software/libraries and the good practices. Beign honestly I feel scared to use the open source libraries as I wish/think at this moment. I feel like as I still write procedural code and not OOP.
Do you know such tutorials, links, blogs, stories, pages?
PS: I know C and PHP. I can't say that I know C++ yet, and that's why I need your help.
Start with one of the most popular Stack Overflow questions.
Then head over to the FLOSS Manuals site for manuals about all sorts of open-source tools.
If you still have questions, use the Stack Overflow search box liberally!
Enjoy!
Many open source projects have their own documentation pages. So if you are willing to use a library or a project you can refer to the documentation.
Or else you want to get involved in any open source projects.
