Asynchronous Programming Using Asp.net Web Api

Want your web application to be scalable, robust and responsive? Read on! The key is to create and code an ASP.NET Web API controller that engages in asynchronous parallel communication with multiple Web APIs, all this without server congestion or blockage of any threads on the server. Be it client side or server side, asynchronous programming has proven to be a challenge for offshore ASP.NET development and it has been relegated to being a job only for . Here, we introduce you to the Task model that marks a definite twist in dealing with more than one asynchronous parallel requests. We promise it will be a lot simpler when you create the API Controller using either Visual Studio 10 or 11.

We take an example of a dynamic web application that requests and procures data from Digg and Delicious RSS sources. The sequence of operations or processes is explained below:

API Controller deals with a query process using a single token.
Digg and Delicious are in turn questioned by the API Controller for stories related to the query token.
Responses from both the sites are bound into a composite form and sent as a unified response back to the client.
Where asynchronous programming comes in is to develop parallel queries to Digg and Delicious, thereby never burdening the threads on the server and optimizing network utilization.
The response to the client is simple and is the equivalent of a collection of stories.
What you need for creating the controller: dual helper processes for processing requests to Digg and Delicious respectively and then the coding of the actual controller to unify them.

Dedicated Hosting Vs Vps Hosting

There are mainly three hosting options are provided by web hosting companies i. e. shared hosting, VPS Hosting and Dedicated Server Hosting.

For an individual with a small website, shared hosting is only an option offered by web hosting companies. But for an organization, want better speed , control, power and functionality over their heavy and community based website, there are two options to consider i. e. Dedicated Server and Virtual Private Server (VPS) hosting.

What is Dedicated Server hosting?

In Dedicated Server Hosting, one physical server is offered by hosting company that is dedicated to you only and you are allowed to customize hardware configurations, operating system and other specifications in according to your website requirement and use the server in the way you want.

What is VPS Hosting ?

In VPS (Virtual Private Server) Hosting, a physical server is shared by many VPS clients that mean you use a server that is virtually divided into many partitions. And one partition is offered to you as a VPS server and you are given limited disk space and bandwidth that you can expand in future in according to your business needs. And you are also allowed to set up your own operating system in such a way to run applications that your website need to perform well. that will not affect to other servers present on the same machine.

Comparison between Dedicated server and VPS Hosting –

A dedicated server will cost you more for maintenance but will provide you more control and high performance than a virtual server.

Dedicated Server provides you full control to customize software and hardware components. On the other hand, VPS provides only software customization and control.

When it comes to flexibility, VPS is preferred due to its greater flexibility to optimize its resources at any given time as website needs grow. In dedicated server all the resources are dedicated to you only, you need to pay for all the resources whether you are them 100% or not.

It is very easy and fast to migrate from one VPS server to another one but in case of dedicated server it is very painful to migrate between two physical servers.

In nutshell, If cost is not concerned and you want high performance for your business,it is recommended to go for dedicated hosting as all the resources are 100% dedicated to you only and you can expand and grow your website in a high performing environment.

And for a small and medium sized business, It is preferred to use VPS Hosting as it is cost effective and more flexible.
You need to be wise in choosing one between them after taking your business needs and future growth into consideration.

Tips to Solve – Error 4294966746 JET_errDatabaseInconsistent in MS Exchange Server

An Exchange Server database is susceptible to different corruption problems, such as dirty database shutdown, antivirus scanning, log file issues, and others. Thus an administrator might require different Microsoft Exchange Recovery tools to solve such problems and to continue working the e-mailing environment.

Further is a scenario that depicts a similar situation of Exchange Server database corruption. As an Exchange Server administrator, you may observe one or more of the below symptoms:

1. You cannot start and/or Information Store service
2. Exchange clients lose the ability to send or receive e-mails. You cannot solve this issue by restarting the server
3. You restore the database from an offline backup but the database is still inconsistent. On running Isinteg utility (database integrity check), it gives the below error message on screen:

“Error 4294966746: JET_errDatabaseInconsistent”

Cause

Information Store is corrupt. Either both or one of public store and private store is corrupted.

Solution

Before trying the below steps, you are recommended to take the backup of the entire Information Store to prevent any post-crash consequences. Use the below steps in order to solve the above problem:

1. Analyze all the error message and events of application event log that Exchange reports on attempting to start the Information Store

2. Run eseutil /mh command to check the integrity of Exchange databases (Priv.edb and Pub.edb). An inconsistent database shows ‘Dirty Shutdown’ state but is not always corrupt. This state can also occur if all the transaction logs have not been committed yet.

3. Replay all the transaction log by performing soft database recovery. For this, execute eseutil /r command for the affected database(s).

4. Run hard database repair in case soft recovery doesn’t work. Run eseutil/ p command and delete all the .chk and .log files

5. Check if the previously occurring symptoms go away. If you can successfully work with the database(s), they are repaired. Next, run eseutil /d and isinteg -pri -fix -test alltests commands in sequence to defragment and fix database issues respectively.

6. In case, the problem remains the same, use a third-party Exchange Server Recovery tool to diagnose and repair the database more effectively. A Microsoft Exchange Recovery utility uses safe, yet powerful, scanning procedures and allows for easy database repair.

Microsoft Exchange Recovery Tool is a professional utility that repairs corrupted Exchange database and extracts the mailboxes in individual *.pst files for Exchange Server 2007, 2003, 2000, and 5.5. The tool provides advanced Exchange Server Recovery features and is easy to use. It can also recover deleted mailboxes and inaccessible STM data.

Drupal And Object Oriented Programming.

As all the OOP languages use CLASS or similar data structures for Object Oriented Programming, we have considered that without a “CLASS”, OOP is not possible.

Object oriented programming (OOP) is quickly taking place over the traditional procedure oriented programming (POP). Programming languages like C# and Java are successful because of OOPs Power.

After gone through the code of “Drupal” – One of the most popular open sources content management system and framework built with PHP language, summary is – Drupal doesnt use a single Class in its code base. Whole Drupal code base is based on just functions. As PHP, with which programming language Drupal itself is built, is also implementing many powerful OPP features, but Drupal is not using these features.

Actually, the OOP concept is not based on uses of data structures like CLASS. It is based on the fundamentals of features like Objects, Abstraction, Encapsulation, Polymorphism, Inheritance etc. If these fundamental features are included in programming then it can be considered in OOP.
There is no keyword ‘class’ in Drupal code. Drupal is as non-OOP as many programmers do. But that is not true. Drupal doesnt contain any class like data structure; still it is still Object Oriented.

Drupal covers all these features without classes. Power of Drupal is hardly depends on this programming structure only. The way, how the hook system has been implemented in Drupal would never been possible with the use of Classes.

Environmental advantages of Suspended Particle Device Glass Technology

The idea of the “home of the future” usually contrasts with the idea of environmental responsibility. The perception of technology being detrimental to ecologicial stability is slowly being replaced with the advent of smart technologies such as Suspended Particle Device or SPD glass.

What is SPD Glass?

In the area of light control, there are three main technologies: polymer liquid crystal devices (PDLC), suspended particle devices (SPD) and Electro chromic devices (EC). All three may be used to produce smart glass, which is described as a glass that can change its light transmission when a voltage is applied. In a nutshell these technologies control the opacity of glass via a control method (sensors, remotes, wall switches etc) to regulate the amount of light allowed to pass through it. SPD is generally the technology of choice for use in external or solar control windows because of its reliability, price, performance, and manufacturing advantages and aesthetics.

Energy and Lighting Costs

In terms of home and office environment SPD glass facades, windows and skylights can be used to more efficiently reduce the need for air conditioning during the summer months and heating during winter.

The ability to instantly switch the glass to maximize daylight when it’s really needed and to provide controllable solar shading during peak light conditions is valuable and unique. SPD Glass has even advanced to the stage where light sensors can automatically adjust the opacity of the glass according to programmed settings. This low energy electric current saves overall temperature control and lighting costs and also reduced carbon emissions related to building maintenance.

Hygiene and Health

These SPD glass panels provide a hygienic alternative to curtains and blinds as they do not trap bacteria, grime and dust. Easily cleaned surfaces mean both a savings on cleaning agents and a cleaner environment for homeowners and building owners. Taking advantage of healthy natural lighting without the glare is the smart way to reduce eye strain and protect the skin from UV damage.

Maintenance savings

Professionally manufactures Suspended Particle Device technologies such as SPD glass utilise a highly durable, solid-state technology with no moving parts to wear out or break. Sun damage such a fading carpets, artwork and furniture is also greatly reduced making your interiors last longer. If you combine this interior longevity with the longevity of the physical glass itself you have a winning combination for your pocket and for the environment.

As more people and businesses become comfortable with the internet, the marketing landscape will continue to evolve quickly in the coming years.

Use of the internet has exploded during the last few years in both the consumer and business-to-business markets. Although the experts still debate the future of the internet, no one doubts it is having an impact on how business is taking place in the twenty ‘first century, even with all of the – – dot crashes – – of the late 1990s. Here are some facts about the internet that highlight its tremendous growth and presence in society:

– The most common products consumers’ research online and purchase off-line (at the store or outlet) are: automobiles, computer, hardware, travel, electronics, books, appliances, music, sporting goods and clothing.

– About 54 percent of the e-mail users have responded to an e-mail advertisement. Almost half purchased a product.

– Internet retail sales account for almost 2.5 percent of all retail sales.

Business-to-business marketers were among the first companies actually to make profits using the internet. In today’s marketplace, the web is becoming the communication tool of choice for many business-to-business companies. The internet provides opportunities for communication, customer service, sales support, collaboration and e-commerce.

Some companies use the internet for every aspect of their business including taking orders, inventory control, production scheduling, communications plans, sales programs, service departments and support programs. The change from traditional communication channels such as salespeople, telephone and – – snail mail – -to the internet and e-mail happened quickly in some companies and more slowly in others.

Now, convincing top management of the benefits of internet marketing is essential. There is still a lack of internet expertise in the business community. As a result, many companies are turning to marketing agencies for guidance.

To conclude, the influence of the internet on various businesses and industries has been clearly noted in today’s world. The presence of the internet and e-commerce is so sweeping that the various applications of web technology are now essential elements of a fully integrated marketing communications program.
