I have no experience with Adobe Air/Flex and want to know, are there some principles (design patterns) for developing Adobe Air/Flex applications?
Thanks.
Flex applications are normally developed using an MVC framework. These frameworks are built on best practices and design patters and determine the (micro) architecture of your Flex app. There are plenty of MVC frameworks available for Flex, see this discussion for a comparison:
Flex MVC Frameworks
No, there are no hard code rules. Just as, if a J2EE becomes too huge and complex you consider using a framework, similarly it will be the case for Flex. If you feel confident that your application size will be within your limits, don't use any framework.
If however, you want to use a framework, there are various choices with some of the best being, Parsley, Cairngorm 2.0, Swiz, PureMVC. However, which framework you should use depends upon your application. If you want to develop an Enterprise app, where you are hitting dataservices to fetch data now and then, use Parsley or Cairngorm 2.0, though if I were you I would prefer to use Parsley.
One important thing you need to take care of though is performance in Flex. Similar things apply to AIR as well.

I spent few days to find out few open source application development libraries/tools for linux based embedded devices. I would like to know which one is mostly preferred in the industry. I understood that Qt is widely used for different embedded domains. Here are some other tools which I just came across
Gtk
Gdk-fb
NanoX
It seems Qt is good in documentation and python bindings are also available. I don't know whether python is really apt for embedded application development.
Any suggestion is really appreciated. Can I go for pyQT for Embedded Application/GUI development?
I would recommend Qt / C++ for an embedded system, if nothing else to avoid the overhead of having Python on the embedded system. Nowadays Qt 4 and 5 comes with JavaScript support - both directly and through QtQuick / QML. This would give you the flexibility of scripting, without bringing Python into the picture.
Beware, though, I'm an old geezer and probably have a view of embedded systems being far more memory constrained that the system that you are planning to use. If you can tell me more about the target hardware, I'm sure that I can help you with a better answer.

What is the whole idea behind One Asp? Is it something like we will be able to develop applications for all asp.net framework without any target framework oriented development using VS IDE. How it can change the usage of ASP.NET in the future?
.Net is a framework. means simply it is a collection of large library to solve different programming needs when a programmer wants to write a software. A library is not of books but of small different collection of code . ASP.net is a .net framework. means one who knows ASP programming then ASP.NET is an extention of ASP in .net framework.
It is mainly used for:
Improved Performance and Scalability
Enhanced Reliability
Easy Deployment
New Application Models
Developer Productivity

I've googled this question repeatedly, but have not found a great answer anywhere. I'm sure someone familiar with ASP.net could answer this pretty easily. What is the best way to connect to a database through ASP.net? LINQ to SQL? Entity framework? I'm not able to find an overview of the different methods to connect or of the place that these technologies have in ASP.net. An explanation or a pointer to a great link would be appreciated. Thanks.
This is, unfortunately, a question without a clear cut answer as it depends on your application need, flavor of database you need to interact with, standards currently in place at your target deployment environment and application design considerations.
Most often relational database access is accomplished in asp.net through either direct or indirect usage of ado.net. If you plan on adhering to common, current practice you should look into using an ORM to speed development time, namely either Entity Framework or NHibernate. (Linq to SQL was great for SQL Server but has been eclipsed by EF.). My preference is NH.
Sorry for the somewhat subjective answer, but this is unintentionally a subjective question.
Good luck!

I'm just getting into ASP.NET web pages with Razor. Based on what it has to offer, would you choose it for your application? It seems to me the ASP.NET MVC framework gives Razor more of an edge because of everything MVC has to offer; it's nice that the web pages framework has some helper components from the WebMatrix DLL, but most of the examples having all the code in one file, plus the reliance on a new set of API's (via webmatrix) is a turnoff to me.
What do you think?
Thanks.
Razor View Engine + ASP.NET MVC is a great combination. Razor definitely seems like the view engine of choice most of the time because it is syntactically much easier to read and work around than ASPX. This benefit alone is huge because you can have developers that are solely focused on HTML and UI development, and have them be able to work around the syntax.
The biggest problem with Razor so far has been it's intellisense support. But, it looks as if the latest version of ReSharper solved that problem nicely, and I'm sure the support for Razor will continue to get better.

I have installed alfresco community edition and want to develop a web application having database connectivity.
I have developed that application using jsp, servlets but want to develop the same application in alfresco.
Can anybody help where to start?
I have written a series of tutorials for people new to the Alfresco platform. I humbly submit those as a good place to start. There are also a number of books available on Alfresco.
It is a little hard to tell what you are trying to do from your brief description, but if you are trying to perform CRUD operations against the repository, I strongly suggest that you start with the Content Management Interoperability Services (CMIS) standard because that gives you a vendor-neutral, language independent way to talk to Alfresco or any other CMIS-compliant repository. My tutorials cover CMIS. You also might be interested in OpenCMIS, which includes a CMIS client API for Java.
That should get you started.
One of the more documented ways is to use Alfresco Web Services Client (I am using alfresco-web-service-client-3.4.d). Its a SOAP client generated from the WSDL provided by Alfreco.
There are good examples on the web. Google for Alfresco+Web+Services+Ingres.
If you have developed the application, then it will definitely help you know the flow and understanding of the application.
