I was trying to save directed graphs into databases for further processing and query. And neo4j seems to fit my needs. However, I don't seem to find a good tutorial regarding the following:
Creating the database and put data in.
Making queries.
I want to be able to do them both manually and automatically (i.e. using a program). The official manual keeps talking about stuff like Maven, Index, REST API and so on, basically things I don't care about at all for now.
So any good hands-on tutorial on neo4j? Or any other graph databases you think is good for total beginners with simple needs (i.e. store graph and query graph)?
For getting started just download the Neo4j Server and start it. Then go to http://localhost:7474 for the integrated web-admin UI which allows you to enter data visually and browser/visualize and query it.
Please have a look at the Neo4j Koans by Jim Webber and Ian Robinson which are material that are used in real-world tutorials. Otherwise also have a look on http://video.neo4j.org for some screencasts and presentations and the collection of introduction links at the neo4j delicious site.
I started a blog for Neo4j beginners. The first four posts are up and they show you how to get neo4j, install it, create some sample data, find friends of friends, six degrees of separation (path finding), use gremlin scripts and cypher queries.
Try http://docs.neo4j.org/chunked/snapshot/tutorials-java-embedded.html or http://docs.neo4j.org/chunked/snapshot/ for more tutorials. Does that work?

I'm starting a project and I'm not sure about what technology to use on the back-end and front-end sides. The project needs to generate charts and a lot of statistics so I have been surfing on the site and I think that the best way to front-end is Backbone.js or Ember.js, is it?
On the other hand I've to decide the server part. I'm an old school developer...Php. I need to develope an API that reads de ddbb and provide the information to the front-end side. I don't know what is the best way to develope a system that let final user to choose a date interval to view their statistics (like Google Analytics, Square, etc.). Maybe Ruby? Symfony as well?
Thx! =)
I was in your same situation months ago and I decided to go for Backbone. The main reason is that it's more used and so it's easier to get help and find good tutorials, plus it's not much opinionated so I think you can learn more while develping and also you can shape your app to fit better your needs. Anyway I didn't tried in deep Ember or Angular so take my opinion with care. For the server side part I've always worked with PHP too, I tried Ruby and I think it's a better support for a webapp but I ended use PHP anyway cause of my company's needs. You can do a good job with PHP too, but I suggest to use frameworks like Silex, Slim or Laravel that are better suited to put up a REST api which you will need if you want to use Backbone.

Can you please guide me to a book, tool or article that would guide me on how to make an asp.net MVC 2 application that uses WCF to perform better?
I am interested in lower database query time.
How to render pages more quickly.
How to write controllers and action and what are the best practices in order to obtain an efficient application.
I use Asp.Net MVC 2 , NHibernate / Entity Framework, WCF 4.0 and JQuery.
Thanks
It may not be the answer you are looking for. I dont think there is a magic tool that will tell you all the problems in all the framework you are using.
I am interested in lower database query time.
For this, you have to use Sql profiler and go through each procedure/query then optimize.
How to render pages more quickly.
Try YSlow from Yahoo. I cant remember tool name from Google. I will add it latter
Check out Hanselmans podcast with Steve Sodders. Creator of YSlow on Web Site Optimization. They talk about various tools on performance tuning.
Sam Saffron works at Stack Overflow and writes numerous articles on performance tuning. This one may be useful for you. Profiling your website like a true Ninja
That's all said, logging is going to be your friend. With good logging, you have more freedom to focus on specific code/component or with AOP tools you can instrument entire app with little code.
I would also add the very easy to use MVC-Mini-profiler. It works with MVC and EF.

Is there a good guide or tutorial for people who need to programmatically interact with dynamic websites? There's been a rash of Perl questions about that lately, and I haven't found a good resource to point people toward. I'm asking not because I need one but because I don't want to waste my time writing it if it already exists. Although I'm most interested in Perl, the extra tools and techniques are mostly the same.
Typically, I see see these problems in people's questions:
Handling, setting, and saving cookies
Finding and interacting with forms
Handling JavaScript inside your user-agent
especially things like onLoad, onSumbit, and Ajax
Using HTTP sniffer tools
Using Web developer plugins in interactive browsers
Interacting with DOM, screen scraping, etc.
If there's no good tutorial, I'll add it to my list of things to do (unless someone else wants to do it). Along the way, if you don't have a suggestion for an existing tutorial, please suggest the things that you think should be in a new one, including links, your favorite tools, and your own user-agent development experiences. I don't care about the particular language you use.
The best I've seen is a Defcon presentation video.
Look at perl library of libraries. Some html parsing libraries should be made for talking to dynamic websites.
Like:
http://metacpan.org/pod/HTML::DOM
But do you want to use web-browser enhanced by perl. Or perl stand alone app?

Is Google Spreadsheets / Docs a viable database option for real-world applications?
Without knowing what this application does, I'd say no. Simply on the basis that a spreadshet != a database.
no, a spreadsheet and a database are distinct concepts. Spreadsheets do not allow you to query the data. Spreadsheets (especially "hosted" like Google's) will not support real world load.
Depends on your application. As a database, typically not. It can be useful in instances where you need "Excel With Web Features" or as an alternative to a database.
Especially now that Spreadsheets, Presentations and Docs are all basically used under the "Google Docs" moniker, the entire "Google Docs" suite is best used as the sum of its parts.
Two examples:
Web forms. Create a form using the Forms application, and all its entrants are stored in a Google Spreadsheet. Personally I've found this to be a pretty quick and easy way to collect names and contact information online, and its all output into a very easy-to-use and portable format.
Using the spreadsheet to interact with other web content. See this example of displaying and grabbing content from Wikipedia for editing: http://ouseful.wordpress.com/2008/10/14/data-scraping-wikipedia-with-google-spreadsheets/
You might see for MySQL, PostgreSQL, SQLite to use in applications, for example, to archive my books.

Where can I get, or how can I generate a large formatted collection of fake user data (names, email address, locations, etc.) that can be used for testing an application?
It can be clearly fake, this will be limited to the development server. But I'm sure anything would be better than what I could come up with.
There are some tools built just for this. I've used http://www.generatedata.com/ before to generate data for MySql databases. RedGate has a nice tool to fill your SQL Server database with test data called SQL Data Generator. The RedGate tool costs about $300, but there is a free trial.
UPDATE:
Faker.js is now available. It is a project built on node.js, and looks pretty comprehensive.
ANOTHER UPDATE: Mockaroo is great!
If you'd like an HTTP API of fake user data, check out Random User Generator
This is a open source tool for generating various types of test data. http://www.generatedata.com
http://www.fakenamegenerator.com/ is a good resource for creating test data with realistic looking users complete with SSN, email address, ... They have a bulk download option too.
Check out this list of "Funny Names" some of them are classic
http://www.ethanwiner.com/funnames.html
Another open source test generator tool is my own http://code.google.com/p/csvtest.
For anyone looking for an updated solution to this problem...
I wrote a test data generator project for Data Synchronisation Studio. It can generate a large dataset ranging from 1 to 100s of millions of rows of realistic testing data (lots of OFs there :D) Anyway, here is a blog post all about it. http://www.simego.com/Blog/2012/02/Test-Data-Generator-Download-for-Data-Sync
