I want to use Neo4j for my web applications. I am using Node.js for the server side. As I understand, I will have to learn Cypher to query the database.
On the website I could find only a Reference guide. I'm looking for some complete tutorial, at least for the introductory part, regarding the integration of this into the website development process. I don't know Java and I don't want to learn it at the moment.
Thanks for sharing!
Having some SQL knowledge, this webinar will take you step by step from 0 to beginner: http://watch.neo4j.org/video/60292144
After this, you will have to refer to your own server-side language to complete the integration, but that should be the most effortless part.
Here are some useful beginner knowledge sources:
Watch the webinars about Cypher on:
http://watch.neo4j.org/
Play around in http://console.neo4j.org
Check out the various node.js drivers that support Cypher--I believe the Thingdom one is the most popular:
https://github.com/thingdom/node-neo4j
Check out examples that use Cypher on Max's blog:
http://maxdemarzi.com/category/cypher/
Luanne posted an excellent guide to query optimization (which may be a bit advanced for newbies, but you should still read it), as well as other Cypher-related posts on the same blog:
http://thought-bytes.blogspot.com/2013/01/optimizing-neo4j-cypher-queries.html
Also, I've posted two introductory blog posts about Cypher just recently, and plan to post more:

The Graph Databases book:

Feel free to post your newbie Cypher questions here--I'll set this to a community wiki in case anyone has any more resources to add.

Hi although this is not technical question, it is important to know where can someone find best from the experts.I am new in JQuery, I am using http://jquery.com/ for learning purposes. But it would be appreciable if I could have some better reference learning site for JQuery where videos and demos are available
So presuming you're somewhat familiar with jQuery, I would advise starting with JavaScript.
Code Academy run through the whole thing and you will understand JavaScript
jQuery's official site has a long, comprehensive list of tutorials. Pick the ones you think are down your alley and run with it.
After that, there are many, many good sites dedicated to jQuery.
Some that you might like are:
http://www.learningjquery.com/
http://jqueryfordesigners.com/
http://visualjquery.com/1.1.2.html (doesn't teach, just think of it as visual docs for the framework)
The New Boston jQuery Video Tutorials
This is a very good site.
I have gone through many tutorials and they are extremely helpful
Just try few videos first and see how much you get from it.
http://listic.ru/jQuery_Cookbook.pdf
found this quite organised and useful.

This question is too general for answers directly in stackoverflow (see this closed question) however I think the community would beneift from having starting points for high quality external articles which can dive into the topic in more detail.
I'd like to see the most informative article on Grails 'Best Practices' based on the following criteria:
how to split tasks between controllers/views/services/domain objects
testing
security
when to use plugins
database design considerations
topics specific to Groovy or Grails that would not be part of general best practice guides
Please answer with a link to an external article adding just a short summary. Please do NOT comment too much on whether you think individual ideas/patterns are good otherwise this question will be closed for 'soliciting debate and discussions'
This InfoQ article on Grails best practices has an excellent list of how to split logic between controllers/views/services/domain, testing, config and other Grails specific considerations.
It's a short article and I'd recommend it to any Grails developer
The GrailsPodcast website just had a good 'best practice' session: http://www.grailspodcast.com/blog/id/249 (currently offline)
There is a presentation by grails persistence expert Burt Beckwith explaining potential performance issues with out-of-the-box usage of hasMany/belongsTo mappings in GORM:
http://burtbeckwith.com/blog/files/169/gorm%20grails%20meetup%20presentation.pdf
Here's an example of how to apply one of the cases that Burt exposes:

We had 2 projects in TFS with same code base. 2 development teams were working on those. We are now merging the code to a one project and this is not an easy task to do manually.
Before starting development in separate we have not used any functionality that TFS provides to make this sort of work easy. Like branching, labeling or any other.
Can I get some guideline or best practices to plan this kind of work so we can adopt it in future to overcome this sort of work.
Link for a TFS guide for developers will also be helpful.
Thanks in advance.
The TFS Branching Guide is probably a good place to start. It will help you with structuring your source based on different usage scenarios
You might also want to look at answers to this questions: How to branch and merge in TFS
In regards to a "TFS guide for developers" the MSDN documentation is a good starting point. Beyond that consider the various books that have been published - there are some good ones out there.

Background about myself:
I have about 3 years experience working in Java/J2EE. I am currently pursuing MS in Software Engineering at a reputed university. I have done several classwork projects on Ruby on Rails and can be considered at Intermediate level expertise with ROR.
I have an interview coming up next week for a Ruby on Rails developer position at a startup. I have already prepared all the basics of Ruby on Rails but didn't get a lot input on the questions asked for ROR developers. Can you guys help me with the preparation? Any materials, suggestions would be welcome.
Here are some responses prepared earlier: What Ruby and Rails Developers Ought To Know?
Some of this is going to depend on the level of the role your are looking at. If I was interviewing someone from the Java world I would be probing to make sure they understood some of the common Ruby idioms, particularly blocks and closures.
Create a github account and made some patch to several project.
Be active in Open source community. It's really a good start

I'm looking for a solution for collaborative filtering in rails or even possible examples. So far I have only found acts_as_recommendable which looks useful but I noticed it hasn't had any updates in the last 2 years.
Does anyone know of any other solutions and/or examples?
Have you evaluated Apache Mahout? It is a Java based solution, with HTTP access to recommendation engine.
Reference:
Introducing Mahout
This pertains to the examples part of your question, as both the libraries mentioned below are in Java.
The article referenced in above answer, written by Apache Mahout-Taste library author, has neat examples, source code of the examples( using 2.5GB wikipedia data) , and an excellent packaging to run and see those examples in action, in a few minutes.
Apache Mahout-Taste
The specific section is Building a recommendation engine
Here is another open source recommendation engine.

In 2013, there's the ActiveRecord Reputation System gem by Twitter. There's also a free RailsCast on the topic.
here is a 50 line recommendation system in Ruby: http://www.igvita.com/2007/01/15/svd-recommendation-system-in-ruby/
there is one link there which doesn't work (when he says "mathies click here" it points to Using linear algebra for intelligent information retrieval by Berry et al.: http://www2.denizyuret.com/ref/berry/berry95using.pdf )
