Web 2.0

We have so many questions related to the Web servers, their versions and many other things. So let’s take an overview of the latest server Web 2.0. Now the question arises – What’s Web 2.0? What is its use? How can we get a thorough review of its usage and so on. So here we present a brief introduction about the mostly discussed topic -
Web 2.0.
Web 2.0 is a novel term coined for the new generation Web applications like start.com, Google maps, Writely and Myspace.com. It is all about harnessing collective intelligence. It was created five years ago, originally known as Web 2.0 Conference (Now known as Web 2.0 Summit). Web 2.0 Summit gathers the intelligence, innovation and leadership of the internet and media industries for a conversation that never fails to stimulate, push and surprise. It was designed to restore confidence in an industry that had lost its way after the dotcom bust. This Web technology provides a platform for user-generated content. Publishing is no longer restricted to a few technical writers – any user can now contribute information. But the information coming from users tends to be highly specific, whereas technical documentation is comprehensive but less specific. User generated content offers an opportunity for technical writers to participate as “curators” by evaluating and organizing the information provided by the end users.
Since 2004, Web 2.0 Summit (formerly Web 2.0 Conference) has brought the intelligence, innovation, and leadership of the Internet industry together in one place at one time. Through incisive plenary sessions, cut-through-the-hype onstage conversations, rapid fire “high order bits” and “show me” presentations, visionaries and executives across key industries present their unique perspective on the Web’s future in-flux and how the tools and principles of Web 2.0 are impacting their businesses. Web 2.0 Summit brings to light how to put the power of the Web to work—its technologies, its business models, and perhaps most importantly, its philosophies of openness, collective intelligence, and transparency .

Advantages and disadvantages of Web 2.0 content
User-generated content tends toward the following characteristics:
1) Authentic : The people contributing content are rarely tactful; their opinions probably don’t reflect official corporate positioning. The fact that information is unfiltered is one of its greatest assets to other readers.
2) Passionate : It takes motivation to write a blog post, participate on a forum, or edit a wiki page. The people creating Web 2.0 content are passionate about the products they are writing about.
3) Specific : User-generated content tends to be about one person’s experience rather than the general workings on the product, so it tends to be quite specialized.
4) Not comprehensive : User-generated content will cover the information that users find interesting or compelling, unlike technical documentation, which is expected to provide universal coverage of the product. User-generated content will go much deeper than technical documentation in places, but it will also have enormous gaps in coverage.
5) Not edited : With the possible exception of content in very large wikis, user-generated content is not edited. The quality of the writing will be as good as the effort that the original author put into the message. Professional content creators add the most value where content curating is needed.
6) Conceptual information and product overviews: A high-level description of a product requires time and attention from someone who understands the entire product. For complex products, discussions of the best implementation approach could be invaluable. Most user-generated content will focus on specific tasks that need to be completed rather than on providing perspective.
7) Thorough coverage of all topics: Instead of focusing on interesting and exciting subject matter exclusively, a professional content creator will ensure that all of the needed topics are discussed in the documentation and user assistance.
8) High production values : The professionals win on quality—user-generated content is rarely edited, copy fitted, or even designed.
9) High-stakes documentation : If documenting by trial and error is out of the question, the professionals are necessary. Some obvious industries where “let the users figure it out” is probably not a very good idea include aerospace, defense, and medical devices.

Users can (and will) play an important part in many industries where their participation is less risky. They are especially good at the following:
1) Providing technical support and workarounds
2) Correcting errors in the official content
3) Highlighting things that are not working
4) Demanding changes where they are needed.

A key competency of the web 2.0 era is discovering implied meta-data and then building a database to capture that meta-data to foster an ecosystem around it .
What Web 2.0 sensibly tells us is that we’ll get to the Internet of Things via a hodgepodge of sensor data contributing bottom-up, to machine learning applications that gradually make more and more sense of the data that is handed to them and I think it’s the future of web services that we are going to make use in the coming years.

PHP Vs .Net

“PHP Vs .NET” , is a hot topic for debate these days. “PHP or .NET : Which is the more Considering Factor ?? ”.
PHP is an Open source scripting language as compared to .NET. .NET is an application framework and not a programming language whereas, PHP can be compared to languages which run under .NET, such as ASP+ or C# .
.NET is the future platform for all the Microsoft technologies but it isn’t solely aimed at the Internet.
Both PHP and .NET are viable solutions for web development, be it in delivering a dynamic web page generated from a database, sending an email, or interfering with a payment gateway, both are perfectly capable. Only the price remains a major issue.
“ PHP isn’t compiled other than when its interpreted at run-time, whereas .NET enjoys all the benefits of being complied” . The use of word “ compiled” in regards of .NET isn’t what a C++ coder would call “compiled”. Zend, the corporate face of PHP projects has been doing this for a while now with the PHP Accelerator. But the given description of accelerator is “Advanced caching ”.
ASP.NET has accountable support from Microsoft. Apart from Zend ( effectively the creators of PHP ), Nusphere ,ThinkPHP and other corporations also provide support for PHP. But we don’t need it; big thanks to the ever-expanding PHP communities.
.NET does offer multiple language support whereas PHP is very flexible and offers useful solutions for the Internet. We don’t expect to be writing a successful website in C#.NET — it is likely that each .NET language will eventually “tune in” to a particular type of application development.
PHP can claim superior object oriented support with PHP 4.3 in its wings. The difference is that .NET will force us to OO approach from start & PHP will not.
Basic notion of templating is to separate logic from content, whereas developers apply the code “behind the scenes”. In PHP, rather than being forced into a single approach, you have the choice of numerous Open Source Projects (Smarty, Pat Template, etc.).
“Corporates don’t like PHP!”. Apart from CBS, PHP is used on many corporate sites of Japan, Switzerland and a lot more countries. Corporations aren’t just using PHP but organizations like Siemens are prepared to go in Partnership to sell PHP to their clients.
In June 2002, PHP took over ASP to become the first Open Source project to start from behind the more popular, the then bespoken Microsoft solutions. The .NET framework has only one real edge over PHP, which wont be making itself apparent for a long time yet: In .NET, you can write an application that will run as a native code on the Website. Microsoft has a long way to go with security before it will be able to unleash it on the Internet and even when that time comes, browsers and content delivery may be sufficiently advanced to make it irrelevant.

Now comes one more interesting blog article on the topic which enumerates the relative pros and cons of content management systems (CMS). A CMS is a collection of procedures used to manage the work flow in a collaborative environment. The main purpose of a CMS is to properly organize unstructured information in one place so that it can be handled and maintained in a systematic way. Let’s get straight to the main topic of discussion: Joomla Vs. Drupal Vs. WordPress – 3 of the most popularly used CMS.

1. The required application server for all three systems is Apache.

2. Database required for all three systems is MySQL, but Joomla and WordPress don’t have an additional database PosgreSQL whereas Drupal works with both MySQL and PosgreSQL.

3. All three of the systems are under the GPL.

4. Friendly URL’s are available on all these systems.

5. Versioning is inbuilt in Drupal but Joomla and WordPress both have free add-ons available for that purpose.

7. Root and shell access to all these systems is not available.

8. All three systems are platform independent.

9. Database replication is limited in Drupal but in the other two it is not possible.

10. The programming language which all of the systems use is PHP.

11. URL rewriting is possible in all three systems.

12. FTP support in Drupal is limited, in Joomla it is not allowed and in WordPress it is given as a free add-on.

13. Commercial support/training is given in Drupal and Joomla whereas in WordPress it is not permitted.

14. Subscription in WordPress is available whereas in Joomla it is limited and in Drupal it is given as a free add-on.
