Trigger

Triggers are special type of stored procedures executed automatically when certain events take place. There are different types of triggers – for update, for insert and for delete. Each trigger is associated with a single database table

Stored Procedure

Stored Procedure is a set of SQL statements stored within a database server and is executed as single entity. Using stored procedures has several advantages over using inline SQL statements, like improved performance and separation of the application logic layer from database layer in n-tier applications

Primary Key

The primary key of a relational table holds a unique value, which identifies each record in the table. It can either be a normal field (column) that is guaranteed to be unique or it can be generated by the database system itself (GUID or Identity field in MS SQL Server for example). Primary keys may be composed of more than 1 field (column) in a table.

Oracle

Oracle is an enterprise relational database management system. Oracle's main rival product MS SQL Server is a low cost alternative offering the same features.

OLE DB

Short for Object Linking and Embedding Data Base. OLE DB is a set of COM-based interfaces that expose data from a range of sources. OLE DB interfaces give applications standardized access to data stored in various information sources like Relational Database Management Systems (MS SQL Server, Oracle, MySQL), small personal databases like MS Access, productivity tools like spreadsheets; plain text files, etc. These interfaces support the amount of DBMS functionality appropriate to the data store, allowing the data store to share its data.

ODBC

Short for Open DataBase Connectivity, a standard database access technology developed by Microsoft Corporation. The purpose of ODBC is to allow accessing any DBMS (DataBase Management System) from any application (as long as the application and the database are ODBC compliant), regardless of which DBMS is managing the data. ODBC achieves this by using a middle layer, called a database driver, between an application and the DBMS. The purpose of this layer is to transform the application's data queries into commands that the DBMS understands. As we said earlier, both the application and the DBMS must be ODBC compliant meaning, the application must be capable of sending ODBC commands and the DBMS must be capable of responding back to them.

Normalization

Normalization is the process of organizing data to minimize redundancy and remove ambiguity. Normalization involves separating a database into tables and defining relationships between the tables. There are three main stages of normalization called normal forms. Each one of those stages increases the level of normalization. The 3 main normal forms are as follows:
First Normal Form (1NF): Each field in a table must contain different information.
Second Normal Form (2NF): All attributes that are not dependent upon the primary key in a database table must be eliminated.
Third Normal Form (3NF): No duplicate information is permitted. So, for example, if two tables both require a common field, this common field information should be separated into a different table.

ADO.....?

Short for Microsoft ActiveX Data Objects. ADO enables your client applications to access and manage data from a range of sources through an OLE DB provider. ADO is built on top of OLE DB and its main benefits are ease of use, high speed, and low memory overhead. ADO makes the task of building complex database enabled client/server and web applications a breeze

ACID...?

ACID short for Atomicity – Consistency – Isolation – Durability and describes the four properties of an enterprise-level transaction:
ATOMICITY: a transaction should be done or undone completely. In the event of an error or failure, all data manipulations should be undone, and all data should rollback to its previous state.
CONSISTENCY: a transaction should transform a system from one consistent state to another consistent state.
ISOLATION: each transaction should happen independently of other transactions occurring at the same time.
DURABILITY: Completed transactions should remain stable/permanent, even during system failure

About hariyana...

Hindi (हिन्दी) is a language spoken in most states in northern and central India. It is an Indo-European language, of the Indo-Iranian subfamily. It evolved from the Middle Indo-Aryan prakrit languages of the middle ages, and indirectly, from Sanskrit. Hindi derives a lot of its higher vocabulary from Sanskrit. Due to Muslim influence in northern India, there are also a number of Persian and Turkish loanwords.

Linguists think of Hindi and Urdu as the same language, the difference being that Hindi is written in Devanagari and draws vocabulary from Sanskrit, while Urdu is written in Arabic script and draws on Persian. The separation is largely a political one; before the partition of India into India and Pakistan, spoken Hindi and Urdu were considered the same language, Hindustani. Since partition, Standard Hindi has developed by replacing many words of Persian origin with Sanskrit words. Hindi and Urdu presently have four standard literary forms: Standard Hindi, Urdu, Dakkhini (Dakhini), and Rehkta. Dakhini is a dialect of Urdu from the Deccan region of south-central India, chiefly from Hyderabad, that uses fewer Persian words. Rehkta is a form of Urdu used chiefly for poetry.

After Chinese, Hindi is the second most spoken language in the world. About 500 million people speak Hindi, in India and abroad, and the total number of people who can understand the language may be 800 million. A 1997 survey found that 66% of all Indians can speak Hindi, and 77% of the Indians regard Hindi as 'one language across the nation'. More than 180 million people in India regard Hindi as their mother tongue. Another 300 million use it as second language.

Outside of India, Hindi speakers are 100,000 in USA; 685,170 in Mauritius; 890,292 in South Africa; 232,760 in Yemen; 147,000 in Uganda; 5,000 in Singapore; 20,000 in New Zealand; 30,000 in Germany. Urdu, the official language of Pakistan, is spoken by about 41 million in Pakistan and other countries. Hindi became one of the official languages of India on January 26, 1965 and it is a minority language in a number of countries, including Fiji, Mauritius, Guyana, Suriname, Trinidad and Tobago, and United Arab Emirates.

Hindi is generally classified in the Central Zone of the Indo-Aryan languages. Khadiboli, the dialect spoken in Western Uttar Pradesh, east of Delhi is the basis for the language used by the government and taught in schools. Hindi is the predominant language in the states and territories of Himachal Pradesh, Delhi, Haryana, Chandigarh, Uttar Pradesh, Rajasthan, Madhya Pradesh, Bihar, as well as the cities of Mumbai and Hyderabad. Is not easy to delimit the borders of the Hindi speaking region. A number of spoken languages are very closely related to Hindi, and may be considered dialects, including Bambaiya Hindi, Bhaya, Braj, Braj Bhasha, Bundeli, Chamari, Ghera, Gowli, Haryanvi, Kanauji, and others. Some of the East-Central Zone languages, including Awadhi (Avadhi), Bagheli, Chhattisgarhi and Dhanwar, and Rajasthani languages, including Marwari, are also widely considered to be dialects of Hindi. There has been considerable controversy on the status of Punjabi and the Bihari languages, including Maithili, Bhojpuri, and Magadhi.

Hindi's popularity has been helped by Bollywood, the Hindi film industry. These movies have an international appeal and now they have broken into the Western markets as well. The beginnings of Hindi literature go back to the Prakrits that are a part of the classical Sanskrit plays. Tulasidas's Ramacharitamanas attained wide popularity. Modern masters include Sumitra Nandan Pant, Maithili Sharan Gupta, Mahadevi Varma, Ajneya.

About Delhi....

You’ve arrived at Delhi. The months of planning and curiosity are over; you’re actually in India. Every experience, every sound, every smell shouts that you’ve arrived somewhere magical. Somewhere Special. It is here that the deep love of one man for one woman created the Taj Mahal; where the King of Kings ruled; where the sacred Ganges flows past holy cities; where the Himalayas stand silent and magnificent; where 5000 years of culture waits to be absorbed.

India’s capital city, Delhi is the second most widely used entry point into the country, being on the route of most major airlines. It is well linked by rail, air and road to all parts of the country. The remains of seven distinctive capital cities – among them Shahjahanabad and Qutab Minar – can be seen. Here, museums, art galleries and cultural centers attract the finest exhibitions and performances from India and abroad. Shopping encompasses virtually everything that can be bought in the country; hotels range from the deluxe to the more modest. Most fascinating of all is the character of Delhi which varies from the 13th century mausoleum of the Lodi kings set in a sprawling park to ultra modern chrome and glass skyscrapers; and from imperial India’s Parliament House and the President’s Palace to the never ending bustle of the walled city surrounding Jama Masjid. Delhi also makes the ideal base for a series of short excursions to neighbouring places, all connected by road.

The capital of India, Delhi blends an historic past and a vibrant present. The Imperial city planned for the British by Lutyens is set in parks and shaded avenues. Legend has it that Delhi, then called Indraprastha, was originally founded around 1200 B.C. by the Pandavas, the august heroesof the epic Mahabharata. Present day Delhi is built around the ruins of seven ancient cities.

Delhi is above all an historic city, an elegant capital, content to leave to Calcutta and Bombay the roles of commercial and business supremacy. It is in fact really two distinct cities; the energy and colour and the thronged bazaars and Moghul architecture of Old Delhi contrast with the formal splendour of New Delhi, whose wide boulevards offer ever-changing perspectives of Lutyen’s landscaped city. Delhi has several world-famous luxury hotels, with the comfort and style to ensure relaxation after your journey; from here, set forth to experience the sights and sounds of the city.

The gracious Red Fort, the Jama Masjid (the largest mosque in India), the Qutab Minar complex with its soaring tower - all are waiting to be explored. Allows some time to wander round the inexpensive modern shops and handicraft centres. Magicians and dancing bears entertain crowds in the marketplaces, while fortune tellers may offer glimpses of the future. The heat of the day gives way to balmy evenings; enjoy a meal in one of the many splendid restaurants, the exotic music of sitars and veenas and the subtle rhythms of the tabla accompanying the delicious cuisines from throughout the country. Flights and trains and buses run from Delhi all over north India, so it is always easy to reach the next destination

Religion....

Most of the people in Himachal are Hindus. There is a sizable number of Buddhists who live in Himachal. Hinduism practiced in the areas of Himachal that are closer to the northern plains is very similar to the Hinduism practiced in the plains.

Upper hill areas have their own distinct flavor of Hinduism. Their practice of religion combines the local legends and beliefs with the larger Hindu beliefs. The temple architecture has also been influenced by local constraints such as availability or lack of availability of certain construction materials. Most of the upper hill temples are made of wood and more similar to Pagodas in design.

Most of the people of Himachal who live in the areas that border with China are Buddhist. There are many beautiful Buddhist temples and pagodas in Himachal.

People in himachal pradesh..

Most of the people in Himachal depend on agriculture for livelihood. Many people derive their income from sheep, goats, and other cattle. Ninety percent of the people live in villages and small towns. Villages usually have terraced fileds and small two storey houses with sloping roof. The villages are mostly self-contained with a few shops to take care of basic necessities of life. Most villages have a temple, where people congregate for worship. In many parts of the Himachal the village Gods are carried on palanquins to village fairs. On Dussehra the largest congregation of village Gods takes place at Kullu.

The SOAP Fault Element

An error message from a SOAP message is carried inside a Fault element.

If a Fault element is present, it must appear as a child element of the Body element. A Fault element can only appear once in a SOAP message.

The SOAP Fault element has the following sub elements:

Sub Element Description
A code for identifying the fault
A human readable explanation of the fault
Information about who caused the fault to happen
Holds application specific error information related to the Body element

The SOAP Body Element

The required SOAP Body element contains the actual SOAP message intended for the ultimate endpoint of the message.

Immediate child elements of the SOAP Body element may be namespace-qualified. SOAP defines one element inside the Body element in the default namespace ("http://www.w3.org/2001/12/soap-envelope"). This is the SOAP Fault element, which is used to indicate error messages.


xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">

Apples

The mustUnderstand Attribute

The SOAP mustUnderstand attribute can be used to indicate whether a header entry is mandatory or optional for the recipient to process.

If you add "mustUnderstand="1" to a child element of the Header element it indicates that the receiver processing the Header must recognize the element. If the receiver does not recognize the element it must fail when processing the Header.

Syntax
soap:mustUnderstand="0|1"

Example

xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">
xmlns:m="http://www.w3schools.com/transaction/"
soap:mustUnderstand="1">
234

...
...

The SOAP Envelope Element

The required SOAP Envelope element is the root element of a SOAP message. It defines the XML document as a SOAP message.

Note the use of the xmlns:soap namespace. It should always have the value of:

http://www.w3.org/2001/12/soap-envelope

and it defines the Envelope as a SOAP Envelope:


xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">
...

Syntax Rules

Here are some important syntax rules:

A SOAP message MUST be encoded using XML
A SOAP message MUST use the SOAP Envelope namespace
A SOAP message MUST use the SOAP Encoding namespace
A SOAP message must NOT contain a DTD reference
A SOAP message must NOT contain XML Processing Instructions

SOAP Building Blocks

A SOAP message is an ordinary XML document containing the following elements:

A required Envelope element that identifies the XML document as a SOAP message
An optional Header element that contains header information
A required Body element that contains call and response information
An optional Fault element that provides information about errors that occurred while processing the message

Why SOAP?

It is important for application development to allow Internet communication between programs.

Today's applications communicate using Remote Procedure Calls (RPC) between objects like DCOM and CORBA, but HTTP was not designed for this. RPC represents a compatibility and security problem; firewalls and proxy servers will normally block this kind of traffic.

A better way to communicate between applications is over HTTP, because HTTP is supported by all Internet browsers and servers. SOAP was created to accomplish this.

SOAP provides a way to communicate between applications running on different operating systems, with different technologies and programming languages.

What is SOAP?

SOAP stands for Simple Object Access Protocol
SOAP is a communication protocol
SOAP is for communication between applications
SOAP is a format for sending messages
SOAP is designed to communicate via Internet
SOAP is platform independent
SOAP is language independent
SOAP is based on XML
SOAP is simple and extensible
SOAP allows you to get around firewalls
SOAP will be developed as a W3C standard

Why is a migration from the MSJVM necessary?

As per a legal agreement between Microsoft and Sun Microsystems, Microsoft is no longer updating the Microsoft Java Virtual Machine (MSJVM) and can only provide fixes for security issues through December 31, 2007. Microsoft cannot provide any other updates to the MSJVM, and after December 31, 2007 the MSJVM becomes obsolete.

Obsolete software, whether in the form of unsupported products, old service packs, or even expired certificates, is an issue every customer needs to be concerned with. Microsoft software life cycle communications help customers identify obsolete software in a proactive and ongoing fashion.

Can I migrate Java-language source code to J# and access it from, say, C# or Visual Basic .NET?

Yes; J# compiles to Microsoft intermediate language (MSIL) and any CLS-compliant language (such as C# or Visual Basic .NET) can utilize code generated by J#. Many customers are using J# to bring Java-language business logic or libraries over to the .NET Framework so that they can be used from their other applications. Likewise, J# can access functionality from assemblies created in C# and other languages.

How would a Java developer use Visual J# .NET?

Visual J# .NET provides functionality equivalent to most of the JDK 1.1.4 libraries and some of the JDK 1.2 libraries. Of course, this level of support isn’t going to allow a full-scale J2EE application to compile without errors on the .NET Framework. But it turns out that this level of JDK functionality actually provides coverage for a great deal of existing business logic, and several customers are using J# for this purpose.



If you are able to separate the business logic from your application (or maybe you have libraries that are entirely business logic) then in many cases you can just compile this with Visual J# .NET and generate an MSIL assembly (that is, a .dll or .exe file) with little or no additional modifications. If there is JDK functionality being used in your code that is not supported with J#, remember that J# has full access to the .NET Framework and chances are good that you can find an equivalent .NET Framework class.

Visual J# .NET

Visual J# .NET brings support for the Java-language syntax to Visual Studio .NET. Visual J# .NET provides developers with full access to the rich set of development libraries found in the .NET Framework while preserving the familiar Java-language syntax. Visual J# .NET also provides functionality equivalent to most of the JDK 1.1.4 libraries, some JDK 1.2 libraries, and most of the libraries included with Visual J++ 6.0.

How do you restrict page errors display in the JSP page?

You first set "Errorpage" attribute of PAGE directory to the name of the error page (ie Errorpage="error.jsp")in your jsp page .Then in the error jsp page set "isErrorpage=TRUE". When an error occur in your jsp page it will automatically call the error page.

How do I prevent the output of my JSP or Servlet pages from being cached by the browser?

You will need to set the appropriate HTTP header attributes to prevent the dynamic content output by the JSP page from being cached by the browser. Just execute the following scriptlet at the beginning of your JSP pages to prevent them from being cached at the browser. You need both the statements to take care of some of the older browser versions.

Why does JComponent have add() and remove() methods but Component does not?

because JComponent is a subclass of Container, and can contain other components and jcomponents. How can I implement a thread-safe JSP page? - You can make your JSPs thread-safe by having them implement the SingleThreadModel interface. This is done by adding the directive <%@ page isThreadSafe="false" % > within your JSP page.

How do I include static files within a JSP page?

Static resources should always be included using the JSP include directive. This way, the inclusion is performed just once during the translation phase. Do note that you should always supply a relative URL for the file attribute. Although you can also include static resources using the action, this is not advisable as the inclusion is then performed for each and every request.

What are stored procedures? How is it useful?

A stored procedure is a set of statements/commands which reside in the database. The stored procedure is pre-compiled and saves the database the effort of parsing and compiling sql statements every time a query is run. Each database has its own stored procedure language, usually a variant of C with a SQL preproceesor. Newer versions of db’s support writing stored procedures in Java and Perl too. Before the advent of 3-tier/n-tier architecture it was pretty common for stored procs to implement the business logic( A lot of systems still do it). The biggest advantage is of course speed. Also certain kind of data manipulations are not achieved in SQL. Stored procs provide a mechanism to do these manipulations. Stored procs are also useful when you want to do Batch updates/exports/houseKeeping kind of stuff on the db. The overhead of a JDBC Connection may be significant in these cases.

Can we use the constructor, instead of init(), to initialize servlet?

Yes , of course you can use the constructor instead of init(). There’s nothing to stop you. But you shouldn’t. The original reason for init() was that ancient versions of Java couldn’t dynamically invoke constructors with arguments, so there was no way to give the constructur a ServletConfig. That no longer applies, but servlet containers still will only call your no-arg constructor. So you won’t have access to a ServletConfig or ServletContext.

How to Retrieve Warnings?

SQLWarning objects are a subclass of SQLException that deal with database access warnings. Warnings do not stop the execution of an application, as exceptions do; they simply alert the user that something did not happen as planned. A warning can be reported on a Connection object, a Statement object (including PreparedStatement and CallableStatement objects), or a ResultSet object. Each of these classes has a getWarnings method, which you must invoke in order to see the first warning reported on the calling object

SQLWarning warning = stmt.getWarnings();
if (warning != null)
{
while (warning != null)
{
System.out.println(\"Message: \" + warning.getMessage());
System.out.println(\"SQLState: \" + warning.getSQLState());
System.out.print(\"Vendor error code: \");
System.out.println(warning.getErrorCode());
warning = warning.getNextWarning();
}
}

HTML for Lists

1. Bulleted Lists:

begins a bulleted, indented list. Each item in the list is then prefaced with the
• tag. It is not necessary to insert a break at the end of each line -- the
• tag automatically creates a new line.
  
  * with
• 
  * with
• 
  * with
• 
  
  2. Numbered Lists:
  begins a numbered, indented list. Each item in the list is then prefaced with the
  1. tag. You need to close the list with the
  tag. Note: You can expand the
  to specify the TYPE of numbering:
  
  
  1 (decimal numbers: 1, 2, 3, 4, 5, ...)
  
  a (lowercase alphabetic: a, b, c, d, e, ...)
  
  A (uppercase alphabetic: A, B, C, D, E, ...)
  
  i (lowercase Roman numerals: i, ii, iii, iv, v, ...)
  
  I (uppercase Roman numerals: I, II, III, IV, V, ...)

How do I get special characters in my HTML?

The special case of the less-than ('<'), greater-than ('>'), and ampersand ('&') characters. In general, the safest way to write HTML is in US-ASCII (ANSI X3.4, a 7-bit code), expressing characters from the upper half of the 8-bit code by using HTML entities.
Working with 8-bit characters can also be successful in many practical situations: Unix and MS-Windows (using Latin-1), and also Macs (with some reservations).
Latin-1 (ISO-8859-1) is intended for English, French, German, Spanish, Portuguese, and various other western European languages. (It is inadequate for many languages of central and eastern Europe and elsewhere, let alone for languages not written in the Roman alphabet.) On the Web, these are the only characters reliably supported. In particular, characters 128 through 159 as used in MS-Windows are not part of the ISO-8859-1 code set and will not be displayed as Windows users expect. These characters include the em dash, en dash, curly quotes, bullet, and trademark symbol; neither the actual character (the single byte) nor its �nnn; decimal equivalent is correct in HTML. Also, ISO-8859-1 does not include the Euro currency character. (See the last paragraph of this answer for more about such characters.)
On platforms whose own character code isn't ISO-8859-1, such as MS-DOS and Mac OS, there may be problems: you have to use text transfer methods that convert between the platform's own code and ISO-8859-1 (e.g., Fetch for the Mac), or convert separately (e.g., GNU recode). Using 7-bit ASCII with entities avoids those problems, but this FAQ is too small to cover other possibilities in detail.
If you run a web server (httpd) on a platform whose own character code isn't ISO-8859-1, such as a Mac or an IBM mainframe, then it's the job of the server to convert text documents into ISO-8859-1 code when sending them to the network.
If you want to use characters not in ISO-8859-1, you must use HTML 4 or XHTML rather than HTML 3.2, choose an appropriate alternative character set (and for certain character sets, choose the encoding system too), and use one method or other of specifying this.

How can I show HTML examples without them being interpreted as part of my document?

Within the HTML example, first replace the "&" character with "&" everywhere it occurs. Then replace the "<" character with "<" and the ">" character with ">" in the same way.
Note that it may be appropriate to use the CODE and/or PRE elements when displaying HTML examples.

What is a DOCTYPE? Which one do I use?

According to HTML standards, each HTML document begins with a DOCTYPE declaration that specifies which version of HTML the document uses. Originally, the DOCTYPE declaration was used only by SGML-based tools like HTML validators, which needed to determine which version of HTML a document used (or claimed to use).
Today, many browsers use the document's DOCTYPE declaration to determine whether to use a stricter, more standards-oriented layout mode, or to use a "quirks" layout mode that attempts to emulate older, buggy browsers.

What is everyone using to write HTML?

Everyone has a different preference for which tool works best for them. Keep in mind that typically the less HTML the tool requires you to know, the worse the output of the HTML. In other words, you can always do it better by hand if you take the time to learn a little HTML.

How comfortable are you with writing HTML entirely by hand?

Very. I don’t usually use WYSIWYG. The only occasions when I do use Dreamweaver are when I want to draw something to see what it looks like, and then I’ll usually either take that design and hand-modify it or build it all over again from scratch in code. I have actually written my own desktop HTML IDE for Windows (it’s called Less Than Slash) with the intention of deploying it for use in web development training. If has built-in reference features, and will autocomplete code by parsing the DTD you specify in the file. That is to say, the program doesn’t know anything about HTML until after it parses the HTML DTD you specified. This should give you some idea of my skill level with HTML.

What is a Hypertext link?

A hypertext link is a special tag that links one page to another page or resource. If you click the link, the browser jumps to the link's destination.

How can I include comments in HTML?

Technically, since HTML is an SGML application, HTML uses SGML comment syntax. However, the full syntax is complex, and browsers don't support it in its entirety anyway. Therefore, use the following simplified rule to create HTML comments that both have valid syntax and work in browsers:

An HTML comment begins with "", and does not contain "--" or ">" anywhere in the comment.
The following are examples of HTML comments:

*
*
*

Do not put comments inside tags (i.e., between "<" and ">") in HTML markup.

How do I create frames? What is a frameset?

Frames allow an author to divide a browser window into multiple (rectangular) regions. Multiple documents can be displayed in a single window, each within its own frame. Graphical browsers allow these frames to be scrolled independently of each other, and links can update the document displayed in one frame without affecting the others.
You can't just "add frames" to an existing document. Rather, you must create a frameset document that defines a particular combination of frames, and then display your content documents inside those frames. The frameset document should also include alternative non-framed content in a NOFRAMES element.
The HTML 4 frames model has significant design flaws that cause usability problems for web users. Frames should be used only with great care.

What is the simplest HTML page?

HTML Code:





This is my message to the world!



Browser Display:
This is my message to the world!

What is a tag?

In HTML, a tag tells the browser what to do. When you write an HTML page, you enter tags for many reasons -- to change the appearance of text, to show a graphic, or to make a link to another page.

What is HTML?

Answer1:
HTML, or HyperText Markup Language, is a Universal language which allows an individual using special code to create web pages to be viewed on the Internet.

Answer2:
HTML ( H yper T ext M arkup L anguage) is the language used to write Web pages. You are looking at a Web page right now.
You can view HTML pages in two ways:
* One view is their appearance on a Web browser, just like this page -- colors, different text sizes, graphics.
* The other view is called "HTML Code" -- this is the code that tells the browser what to do.

Design Aims

In designing XHTML, a number of design aims were kept in mind to help direct the design. These included:

As generic XML as possible: if a facility exists in XML, try to use that rather than duplicating it.
Less presentation, more structure: already mentioned above.
More usability: try to make the language easy to write, and make the resulting documents easy to use.
More accessibility: some call it 'designing for our future selves'; the design should be as inclusive as possible.
Better internationalization: it is a World Wide Web.
More device independence: new devices coming online, such as telephones, PDAs, tablets, televisions and so on mean that it is imperative to have a design that allows you to author once and render in different ways on different devices, rather than authoring new versions of the document for each type of device.
Less scripting: achieving functionality through scripting is difficult for the author and restricts the type of user agent you can use to view the document. We have tried to identify current typical usage, and include those usages in markup.

XHTML2 and Presentation

The original version of HTML was designed to represent the structure of a document, not its presentation. Even though presentation-oriented elements were later added to the language by browser manufacturers, HTML is at heart a document structuring language. XHTML2 takes HTML back to these roots, by removing all presentation elements, and subordinating all presentation to stylesheets. This gives greater flexibility, and more powerful presentation possibilities, since CSS can do more than the presentational elements of HTML ever did.

What is XHTML 2?

XHTML 2 is a general purpose markup language designed for representing documents for a wide range of purposes across the World Wide Web. To this end it does not attempt to be all things to all people, supplying every possible markup idiom, but to supply a generally useful set of elements, with the possibility of extension using the span and div elements in combination with stylesheets.

Why are you leaving (or did you leave) this position ?
(If you have a job presently tell the hr)

If you’re not yet 100% committed to leaving your present post, don’t be afraid to say so. Since you have a job, you are in a stronger position than someone who does not. But don’t be coy either. State honestly what you’d be hoping to find in a new spot. Of course, as stated often before, you answer will all the stronger if you have already uncovered what this position is all about and you match your desires to it.

(If you do not presently have a job tell the hr.)

Never lie about having been fired. It’s unethical – and too easily checked. But do try to deflect the reason from you personally. If your firing was the result of a takeover, merger, division wide layoff, etc., so much the better.

But you should also do something totally unnatural that will demonstrate consummate professionalism. Even if it hurts , describe your own firing – candidly, succinctly and without a trace of bitterness – from the company’s point-of-view, indicating that you could understand why it happened and you might have made the same decision yourself.

Your stature will rise immensely and, most important of all, you will show you are healed from the wounds inflicted by the firing. You will enhance your image as first-class management material and stand head and shoulders above the legions of firing victims who, at the slightest provocation, zip open their shirts to expose their battle scars and decry the unfairness of it all.

For all prior positions:

Make sure you’ve prepared a brief reason for leaving. Best reasons: more money, opportunity, responsibility or growth.

Tell me about something you did – or failed to do – that you now feel a little ashamed of ?
As with faults and weaknesses, never confess a regret. But don’t seem as if you’re stonewalling either.

Best strategy: Say you harbor no regrets, then add a principle or habit you practice regularly for healthy human relations.

Example: Pause for reflection, as if the question never occurred to you. Then say to hr, “You know, I really can’t think of anything.” (Pause again, then add): “I would add that as a general management principle, I’ve found that the best way to avoid regrets is to avoid causing them in the first place. I practice one habit that helps me a great deal in this regard. At the end of each day, I mentally review the day’s events and conversations to take a second look at the people and developments I’m involved with and do a double check of what they’re likely to be feeling. Sometimes I’ll see things that do need more follow-up, whether a pat on the back, or maybe a five minute chat in someone’s office to make sure we’re clear on things…whatever.”

“I also like to make each person feel like a member of an elite team, like the Boston Celtics or LA Lakers in their prime. I’ve found that if you let each team member know you expect excellence in their performance…if you work hard to set an example yourself…and if you let people know you appreciate and respect their feelings, you wind up with a highly motivated group, a team that’s having fun at work because they’re striving for excellence rather than brooding over slights or regrets.”

What are your greatest weaknesses ?
Disguise a strength as a weakness.

Example: “I sometimes push my people too hard. I like to work with a sense of urgency and everyone is not always on the same wavelength.”

Drawback: This strategy is better than admitting a flaw, but it's so widely used, it is transparent to any experienced interviewer.

BEST ANSWER: (and another reason it's so important to get a thorough description of your interviewer's needs before you answer questions): Assure the interviewer that you can think of nothing that would stand in the way of your performing in this position with excellence. Then, quickly review you strongest qualifications.

Example: “Nobody's perfect, but based on what you've told me about this position, I believe I' d make an outstanding match. I know that when I hire people, I look for two things most of all. Do they have the qualifications to do the job well, and the motivation to do it well? Everything in my background shows I have both the qualifications and a strong desire to achieve excellence in whatever I take on. So I can say in all honesty that I see nothing that would cause you even a small concern about my ability or my strong desire to perform this job with excellence.”

Alternate strategy (if you don't yet know enough about the position to talk about such a perfect fit):

Instead of confessing a weakness, describe what you like most and like least, making sure that what you like most matches up with the most important qualification for success in the position, and what you like least is not essential.

Example: Let's say you're applying for a teaching position. “If given a choice, I like to spend as much time as possible in front of my prospects selling, as opposed to shuffling paperwork back at the office. Of course, I long ago learned the importance of filing paperwork properly, and I do it conscientiously. But what I really love to do is sell (if your interviewer were a sales manager, this should be music to his ears.)

What are your greatest strengths ?

You know that your key strategy is to first uncover your interviewer's greatest wants and needs before you answer questions. And from Question 1, you know how to do this.

Prior to any interview, you should have a list mentally prepared of your greatest strengths. You should also have, a specific example or two, which illustrates each strength, an example chosen from your most recent and most impressive achievements.

You should, have this list of your greatest strengths and corresponding examples from your achievements so well committed to memory that you can recite them cold after being shaken awake at 2:30AM.

Then, once you uncover your interviewer's greatest wants and needs, you can choose those achievements from your list that best match up.

As a general guideline, the 10 most desirable traits that all employers love to see in their employees are:

A proven track record as an achiever...especially if your achievements match up with the employer's greatest wants and needs.

Intelligence...management "savvy".

HR Interview Questions Answers .....?

Tell me about yourself ?
Start with the present and tell why you are well qualified for the position. Remember that the key to all successful interviewing is to match your qualifications to what the interviewer is looking for. In other words you must sell what the buyer is buying. This is the single most important strategy in job hunting.

So, before you answer this or any question it's imperative that you try to uncover your interviewer's greatest need, want, problem or goal.

To do so, make you take these two steps:
Do all the homework you can before the hr interview to uncover this person's wants and needs (not the generalized needs of the industry or company)

As early as you can in the interview, ask for a more complete description of what the position entails. You might say: “I have a number of accomplishments I'd like to tell you about, but I want to make the best use of our time together and talk directly to your needs. To help me do, that, could you tell me more about the most important priorities of this position? All I know is what I (heard from the recruiter, read in the classified ad, etc.)”

Then, ALWAYS follow-up with a second and possibly, third question, to draw out his needs even more. Surprisingly, it's usually this second or third question that unearths what the interviewer is most looking for.

You might ask simply, "And in addition to that?..." or, "Is there anything else you see as essential to success in this position?:

This process will not feel easy or natural at first, because it is easier simply to answer questions, but only if you uncover the employer's wants and needs will your answers make the most sense. Practice asking these key questions before giving your answers, the process will feel more natural and you will be light years ahead of the other job candidates you're competing with.

After uncovering what the employer is looking for, describe why the needs of this job bear striking parallels to tasks you've succeeded at before. Be sure to illustrate with specific examples of your responsibilities and especially your achievements, all of which are geared to present yourself as a perfect match for the needs he has just described.

Be natural
Many interviewees adopt a stance which is not their natural self.
It is amusing for interviewers when a candidate launches into an accent which he or she cannot sustain consistently through the interview or adopt mannerisms that are inconsistent with his/her personality.
Interviewers appreciate a natural person rather than an actor.
It is best for you to talk in natural manner because then you appear genuine.

Eye contact
You must maintain eye contact with the panel, right through the interview. This shows your self-confidence and honesty.
Many interviewees while answering, tend to look away. This conveys you are concealing your own anxiety, fear and lack of confidence.
Maintaining an eye contact is a difficult process. As the circumstances in an interview are different, the value of eye contact is tremendous in making a personal impact.

Humor
A little humor or wit thrown in the discussion occasionally enables the interviewers to look at the pleasant side of your personality,. If it does not come naturally do not contrive it.
By injecting humor in the situation doesn’t mean that you should keep telling jokes. It means to make a passing comment that, perhaps, makes the interviewer smile.

The interviewer normally pays more attention if you display an enthusiasm in whatever you say.
This enthusiasm come across in the energetic way you put forward your ideas.
You should maintain a cheerful disposition throughout the interview, i.e. a pleasant countenance hold s the interviewers interest.

Tips For HR Interview...?

Entering the room
Prior to the entering the door, adjust your attire so that it falls well.
Before entering enquire by saying, “May I come in sir/madam”.
If the door was closed before you entered, make sure you shut the door behind you softly.
Face the panel and confidently say ‘Good day sir/madam’.
If the members of the interview board want to shake hands, then offer a firm grip first maintaining eye contact and a smile.
Seek permission to sit down. If the interviewers are standing, wait for them to sit down first before sitting.
An alert interviewee would diffuse the tense situation with light-hearted humor and immediately set rapport with the interviewers.

How many people have held the position in the past several years?

Knowing how many people have been in your job and why they left can offer you great insights. You'll want to know if they were promoted or quit altogether. A steady stream of resignations may be a sign you could be reentering the job market soon.

While many of the reasons positions eventually become unfulfilling are unavoidable, such as hitting a plateau after repeatedly performing the same duties, job seekers should consider the ways a new position will advance them

How many of my skills and experiences will I be able to use and learn?

Make sure your unique skills and talents will be used and that training and promotion are open in the future. When you decide to move on, you'll want to have a new crop of experiences to sell to your next employer. Your goal is to perform well at work while constantly growing and learning.

How much change is in the works at your prospective company, and what kind?

Constant change at work can mean constant stress. Find out if there are any big changes coming, such as new processing systems or management, impending retirements or adoption of new procedures that still need to be ironed out. At the same time, remember that some of these transitions will have less effect on your position than others.

What are the boss's strengths and weaknesses?

This question can be tough to answer, and it's best saved for after the job offer has been extended. You'll want to get a good idea for your potential boss's management style. Speak to your potential boss as much as possible to get a feel for his personality and what you can live with. Does he micromanage? Will you get consistent feedback and reviews? Does he make small talk, or is every conversation strictly business?

Will the actual work and job responsibilities provide gratification, fulfillment and challenge?

This question is often overlooked, because applicants get hung up on job titles, salary and benefits. Try to get a clear sense of what an actual day would be like. What will you spend the majority of your time doing? Is the work in line with your values? Will you likely learn this job quickly and become bored and unchallenged?

What to Ask After the Offer...?

All job hunters are waiting for that call -- the one that says they've landed the job. But as eager as you may be to escape either your current job or the unemployment ranks, don't abdicate your power position once the offer comes in. Now it's your turn to sit in the interviewer's seat and ask the company and yourself some tough questions -- the answers to which could mean the difference between career bliss and disaster.

What are three ways in which a thread can enter the waiting state?

A thread can enter the waiting state by invoking its sleep() method, by blocking on IO, by unsuccessfully attempting to acquire an object's lock, or by invoking an object's wait() method. It can also enter the waiting state by invoking its (deprecated) suspend() method.

What are synchronized methods and synchronized statements?

Synchronized methods are methods that are used to control access to a method or an object. A thread only executes a synchronized method after it has acquired the lock for the method's object or class. Synchronized statements are similar to synchronized methods. A synchronized statement can only be executed after a thread has acquired the lock for the object or class referenced in the synchronized statement.

What is synchronization and why is it important?

With respect to multithreading, synchronization is the capability to control the access of multiple threads to shared resources. Without synchronization, it is possible for one thread to modify a shared object while another thread is in the process of using or updating that object's value. This often causes dirty data and leads to significant errors

What do you understand by Synchronization?

Synchronization is a process of controlling the access of shared resources by the multiple threads in such a manner that only one thread can access one resource at a time. In non synchronized multithreaded application, it is possible for one thread to modify a shared object while another thread is in the process of using or updating the object's value.
Synchronization prevents such type of data corruption.
E.g. Synchronizing a function:
public synchronized void Method1 () {
// Appropriate method-related code.
}
E.g. Synchronizing a block of code inside a function:
public myFunction (){
synchronized (this) {
// Synchronized code here.
}
}

Name the containers which uses Border Layout as their default layout?

Containers which uses Border Layout as their default are: window, Frame and Dialog classes.

What's the difference between an interface and an abstract class?

An abstract class may contain code in method bodies, which is not allowed in an interface. With abstract classes, you have to inherit your class from it and Java does not allow multiple inheritance. On the other hand, you can implement multiple interfaces in your class.

How could Java classes direct program messages to the system console, but error messages, say to a file?

The class System has a variable out that represents the standard output, and the variable err that represents the standard error device. By default, they both point at the system console. This how the standard output could be re-directed:
Stream st = new Stream(new FileOutputStream("output.txt")); System.setErr(st); System.setOut(st);

An application needs to load a library before it starts to run, how to code?

One option is to use a static block to load a library before anything is called. For example,
class Test {
static {
System.loadLibrary("path-to-library-file");
}
....
}
When you call new Test(), the static block will be called first before any initialization happens. Note that the static block position may matter

What is NullPointerException and how to handle it?

When an object is not initialized, the default value is null. When the following things happen, the NullPointerException is thrown:
--Calling the instance method of a null object.
--Accessing or modifying the field of a null object.
--Taking the length of a null as if it were an array.
--Accessing or modifying the slots of null as if it were an array.
--Throwing null as if it were a Throwable value.
The NullPointerException is a runtime exception. The best practice is to catch such exception even if it is not required by language design.

What is more advisable to create a thread, by implementing a Runnable interface or by extending Thread class?

Strategically speaking, threads created by implementing Runnable interface are more advisable. If you create a thread by extending a thread class, you cannot extend any other class. If you create a thread by implementing Runnable interface, you save a space for your class to extend another class now or in future.

Jack developed a program by using a Map container to hold key/value pairs. He wanted to make a change to the map. He decided to make a clone of the ma

If Jack made a clone of the map, any changes to the clone or the original map would be seen on both maps, because the clone of Map is a shallow copy. So Jack made a wrong decision.

Can you have virtual functions in Java?

Yes, all functions in Java are virtual by default. This is actually a pseudo trick question because the word "virtual" is not part of the naming convention in Java (as it is in C++, C-sharp and VB.NET), so this would be a foreign concept for someone who has only coded in Java. Virtual functions or virtual methods are functions or methods that will be redefined in derived classes.

What does a well-written OO program look like?

A well-written OO program exhibits recurring structures that promote abstraction, flexibility, modularity and elegance

What is Java?

Java is an object-oriented programming language developed initially by James Gosling and colleagues at Sun Microsystems. The language, initially called Oak (named after the oak trees outside Gosling's office), was intended to replace C++, although the feature set better resembles that of Objective C. Java should not be confused with JavaScript, which shares only the name and a similar C-like syntax. Sun Microsystems currently maintains and updates Java regularly

How are Observer and Observable used?

Objects that subclass the Observable class maintain a list of observers. When an Observable object is updated, it invokes the update() method of each of its observers to notify the observers that it has changed state. The Observer interface is implemented by objects that observe Observable objects.

Which containers use a border layout as their default layout?

The Window, Frame and Dialog classes use a border layout as their default layout

What is a transient variable in Java?

A transient variable is a variable that may not be serialized. If you don't want some field to be serialized, you can mark that field transient or static.

What is the difference between Serializalble and Externalizable interface?

When you use Serializable interface, your class is serialized automatically by default. But you can override writeObject() and readObject() two methods to control more complex object serailization process. When you use Externalizable interface, you have a complete control over your class's serialization process.

How many methods in the Externalizable interface?

There are two methods in the Externalizable interface. You have to implement these two methods in order to make your class externalizable. These two methods are readExternal() and writeExternal().

How many methods in the Serializable interface?

There is no method in the Serializable interface. The Serializable interface acts as a marker, telling the object serialization tools that your class is serializable.

If a class is located in a package, what do you need to change in the OS environment to be able to use it?

You need to add a directory or a jar file that contains the package directories to the CLASSPATH environment variable. Let's say a class Employee belongs to a package com.xyz.hr; and is located in the file c:\dev\com\xyz\hr\Employee.java. In this case, you'd need to add c:\dev to the variable CLASSPATH. If this class contains the method main(), you could test it from a command prompt window as follows:
c:\>java com.xyz.hr.Employee

How to define an Interface in Java ?

In Java Interface defines the methods but does not implement them. Interface can include constants. A class that implements the interfaces is bound to implement all the methods defined in Interface.
Emaple of Interface:

public interface sampleInterface {
public void functionOne();

public long CONSTANT_ONE = 1000;
}

Java Interview Questions - How to define an Abstract class?

A class containing abstract method is called Abstract class. An Abstract class can't be instantiated.
Example of Abstract class:
abstract class testAbstractClass {
protected String myString;
public String getMyString() {
return myString;
}
public abstract string anyAbstractFunction();
}

What is similarities/difference between an Abstract class and Interface?

Differences are as follows:
Interfaces provide a form of multiple inheritance. A class can extend only one other class. Interfaces are limited to public methods and constants with no implementation. Abstract classes can have a partial implementation, protected parts, static methods, etc.
A Class may implement several interfaces. But in case of abstract class, a class may extend only one abstract class. Interfaces are slow as it requires extra indirection to to find corresponding method in in the actual class. Abstract classes are fast.
Similarities:

Neither Abstract classes or Interface can be instantiated.

Is Iterator a Class or Interface? What is its use?

Answer: Iterator is an interface which is used to step through the elements of a Collection

What is Collection API ?

The Collection API is a set of classes and interfaces that support operation on collections of objects. These classes and interfaces are more flexible, more powerful, and more regular than the vectors, arrays, and hashtables if effectively replaces.
Example of classes: HashSet, HashMap, ArrayList, LinkedList, TreeSet and TreeMap.
Example of interfaces: Collection, Set, List and Map.

What is asp web forms?

The ASP.NET Web Forms page framework is a scalable common language runtime programming model that can be used on the server to dynamically generate Web pages.

Intended as a logical evolution of ASP (ASP.NET provides syntax compatibility with existing pages), the ASP.NET Web Forms framework has been specifically designed to address a number of key deficiencies in the previous model. In particular, it provides:

The ability to create and use reusable UI controls that can encapsulate common functionality and thus reduce the amount of code that a page developer has to write.
The ability for developers to cleanly structure their page logic in an orderly fashion (not "spaghetti code").
The ability for development tools to provide strong WYSIWYG design support for pages (existing ASP code is opaque to tools).

ASP.NET is a programming framework built on the common language runtime that can be used on a server to build powerful Web applications. ASP.NET offers several important advantages over previous Web development models:

Enhanced Performance. ASP.NET is compiled common language runtime code running on the server. Unlike its interpreted predecessors, ASP.NET can take advantage of early binding, just-in-time compilation, native optimization, and caching services right out of the box. This amounts to dramatically better performance before you ever write a line of code.


World-Class Tool Support. The ASP.NET framework is complemented by a rich toolbox and designer in the Visual Studio integrated development environment. WYSIWYG editing, drag-and-drop server controls, and automatic deployment are just a few of the features this powerful tool provides.


Power and Flexibility. Because ASP.NET is based on the common language runtime, the power and flexibility of that entire platform is available to Web application developers. The .NET Framework class library, Messaging, and Data Access solutions are all seamlessly accessible from the Web. ASP.NET is also language-independent, so you can choose the language that best applies to your application or partition your application across many languages. Further, common language runtime interoperability guarantees that your existing investment in COM-based development is preserved when migrating to ASP.NET.


Simplicity. ASP.NET makes it easy to perform common tasks, from simple form submission and client authentication to deployment and site configuration. For example, the ASP.NET page framework allows you to build user interfaces that cleanly separate application logic from presentation code and to handle events in a simple, Visual Basic - like forms processing model. Additionally, the common language runtime simplifies development, with managed code services such as automatic reference counting and garbage collection.


Manageability. ASP.NET employs a text-based, hierarchical configuration system, which simplifies applying settings to your server environment and Web applications. Because configuration information is stored as plain text, new settings may be applied without the aid of local administration tools. This "zero local administration" philosophy extends to deploying ASP.NET Framework applications as well. An ASP.NET Framework application is deployed to a server simply by copying the necessary files to the server. No server restart is required, even to deploy or replace running compiled code.


Scalability and Availability. ASP.NET has been designed with scalability in mind, with features specifically tailored to improve performance in clustered and multiprocessor environments. Further, processes are closely monitored and managed by the ASP.NET runtime, so that if one misbehaves (leaks, deadlocks), a new process can be created in its place, which helps keep your application constantly available to handle requests.


Customizability and Extensibility. ASP.NET delivers a well-factored architecture that allows developers to "plug-in" their code at the appropriate level. In fact, it is possible to extend or replace any subcomponent of the ASP.NET runtime with your own custom-written component. Implementing custom authentication or state services has never been easier.


Security. With built in Windows authentication and per-application configuration, you can be assured that your applications are secure.

Tree view declaration in Asp.net?

TreeView Declaration

Grid view?

As a result of not setting the DataSourceID property of the GridView to a DataSourceControl DataSource, you have to add event handlers for sorting and paging.



private string ConvertSortDirectionToSql(SortDirection sortDireciton)
{
string newSortDirection = String.Empty;

switch (sortDirection)
{
case SortDirection.Ascending:
newSortDirection = "ASC";
break;

case SortDirection.Descending:
newSortDirection = "DESC";
break;
}

return newSortDirection
}

protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gridView.PageIndex = e.NewPageIndex;
gridView.DataBind();
}

protected void gridView_Sorting(object sender, GridViewSortEventArgs e)
{
DataTable dataTable = gridView.DataSource as DataTable;

if (dataTable != null)
{
DataView dataView = new DataView(dataTable);
dataView.Sort = e.SortExpression + " " + ConvertSortDirectionToSql(e.SortDirection);

gridView.DataSource = dataView;
gridView.DataBind();
}
}

Sruthi Kamal's new endeavour

Kamal Haasan's daughter Sruthi Haasan is all geared up top come out with music albums. Her father has been constructing a state-of-the-art recording studio for his daughter in Chennai.

The studio will be utilized by Sruthi Haasan to pursue her career in music. Having learnt both Western and Carnatic music, Sruthi Haasan is keen on turning a music composer, though she has been getting a lot of offers to act.

She has even sung a song in Dasavatharam, set to tunes by Himesh Reshmaiyya. Search is on to find a suitable name for the recording studio.

Kamal bravura show

Kamal Haasan appeared at a court in Chennai on Thursday over a complaint lodged in regard to his up and coming Dasavatharam.

An assistant director Senthil Kumar had filed a complaint alleging that Dasavatharam was his own story and that the producers, actor and director of the movie had cheated him.

Dasavatharam is a big budgeted films produced by Oscar films Ravichandran. Kamal Hassan is playing 10 different roles in this film. The script is written by Kamal and director K S Ravikumar is directing the film. According to the producer, this film is nearing its final stage of shooting and slated for Diwali release.

Kamal Haasan appeared before the judge on Thursday and contended that no plagiarism was involved in it. He stated that it was his own story. Kamal Haasan and his Counsel appeared before the Judge and explained to him in detail. Also they agreed to submit an English version of the script of Dasavatharam.

Kamal Haasan had stated that he had been in the industry for the past few decades and won several awards and acclaims and that there is no need to lift the stories of others.

Avid Kamal fans and media men gathered in large numbers at the High Court to catch a glimpse of Kamal Haasan.

Dasavatharam for Pongal

Kamal Haasan's much-talked about Dasavatharam was expected for a Deepavali release. But the latest rumors doing rounds is that its release would be postponed and the movie may hit the screens only for Pongal.

With the shooting for the talkies portion of the film and a couple of song sequences completed, two songs remain to be shot. The crew is expected to wind up shooting soon.

The post-production work, including graphics, is likely to stretch out for the next three months. Being the top-notch perfectionist, Kamal said to have insisted on high-quality graphics work and fans could be in for a visual treat.

Featuring Kamal Haasan in ten different roles, the movie features Asin, Mallika Sherawat and Nelpolean in prominent roles. Music is by Himseh Reshmaiyya and direction by K S Ravi Kumar.

Kamal’s plans for Dasavatharam

Kamal Haasan is now fully immersed in the post-production works of Dasavatharam.

One of the much-expected films of Tamil Cinema, the shooting for Dasavatharam is almost completed and the dubbing works have commenced.

Kamal Haasan is keen to ensure that he try novel methods in post-production especially in dubbing and getting the computer graphics works right.

Dasavatharam features Kamal Haasan in ten roles and directed by K S Ravikumar. The movie was shot for almost a year and the cast and crew have expressed confidence that the movie would bring laurels to Tamil cinema.

Plans are on to release the movie this Deepavali. Asin, Mallika Sherwat, Jayapradha, Nepolean among others are in the cast.

css

External stylesheets contain cascading stylesheet, or CSS, information used by a browser to display your web page with the styles you intended to use. These styles can be as simple as defining the font and font color, to as complex as layouts with three column without using tables.
There are four different ways CSS information can be supplied. See cascading order of CSS for more information.
The most efficient way to supply a browser with CSS information is by using an external css stylesheet.
What is an external CSS stylesheet?
An external CSS stylesheet is a separate file containing all the style information for a web site. These files have a .css extension and are commonly named style.css. The name of the file is irrelevant.
Why use an external CSS stylesheet
The benefits of an external stylesheet are:
Reduced bandwidth. Browsers typically only request one copy of your external CSS stylesheet, then caches that copy and won’t request your server for another copy for a certain period of time. The cache can be over written by refreshing the page. If this doesn’t work, try refreshing the external stylesheet itself.
External CSS stylesheets also reduces bandwidth by enabling your html code to be a clearer and contain less redundant style information. The smaller your file size, the less bandwidth is required to send the file out to the browser. For example, if wanted all tags of your web site to be vertically aligned in the center, instead of using for every single tag in your html document, simply define the vertical alignment in the external stylesheet and in your html document, all you will need to use is and all will be vertically aligned.
Easier to maintain. Instead of defining a style for a particular element over and over again, you only need to define it once in external stylesheet. External stylesheets also enable altering the whole look of a web site by changing one file, the .css file.
How do I create an external CSS stylesheet
External CSS stylesheets can be created using a simple text editor. Most PC’s have Text Pad which is the standard text editor, Mac’s have TextEdit which is the standard text editor. I recommend BBEdit on Macs as a text editor as it has many features a standard text editor doesn’t usually have.
To create an external CSS stylesheet, open up a new file and enter in the style information for that site. For example (as taken from Zann Marketing’s Developer blog styles):

measles

Measles is an infection caused by a virus (a viral infection). The virus is called Pramyxovirus. In the developed world it used to be very common. However, thanks to extensive immunisation programmes the number of children infected has gone down considerably. Many health care professionals are concerned that the numbers of infected children has recently started to rise. The main reason being that some parents are scared of immunizing their children as they are worried about the vaccine's safety. How do you catch measles? If you have never had measles before and were never immunised you can catch it. It is a very contagious virus. If you live in a house with someone who has measles you run a 90% chance of becoming infected. The infected person transmits the virus through the nose and mouth - the virus is carried in tiny droplets in the air. Infected saliva and nasal secretions are also a source of transmission. Measles and PregnancyIf you have measles you should stay well away from pregnant women as the disease is especially dangerous for the unborn child. If you know of any pregnant woman who has been in contact with an adult or child infected with measles you should advise her to see her doctor immediately. What are the symptoms of measles? The patient will have a general feeling of being unwell (initial symptom). He/she will have a runny nose, a hacking cough and red eyes. His/her temperture will rise to over 40C and he/she will complain of body aches. Some children will suddenly become sensitive to bright lights. The patient will have small, red, irregularly-shaped spots with blue or white centres (Koplik's spots). These usually start inside the mouth a couple of days before the person comes out with a measles skin rash, which normally starts around the head and neck - gradually covering the whole body. Within three days the person has a rash which covers from head to toe. This rash starts off with small red spots, later on they join up and the patient has large blotchy red areas on the skin. The blotches can also be brownish in colour, but are more often red. The rash lasts just under a week. Measles is easy to diagnoseA measles rash is quite unique and easy for a doctor to identify. In the UK every case of measles must be reported to the HPA (Health Protection Agency). When you take your child (or adult or yourself) to your GP (Primary Health Physician, Family Doctor) you should phone first so that they can arrange for you to sit in a separate waiting area from other patients. How do you treat measles? There is no treatment for the virus, you have to let it run its course. However, there is treatment for some of the symptoms. Antibiotics will not treat the virus (antibiotics are for bacteria). However, if the patient develops an eye or ear infection an antibiotic may then be indicated. Make sure the infected person, especially children, take plenty of fluids (measles patients become dehydrated quickly). Drinking plenty of fluids is much more important than eating solids. If your child is not hungry for a couple of day, don't worry - but make sure he/she drinks a lot. OutlookMost people recover completely. A small number may go on to develop complications, such as encephalitis (inflammation of the brain), pneumonia, croup, bronchiolitis and hepatitis. 5% of measles patients may develop otitis media or pneumonia. One in 1000 develops encephalitis. How to protect yourself and your children? There is a vaccine, called MMR (Measles, Mumps Rubella). In the UK most children are immunized with the MMR vaccine. The first shot is given when the child is 14 months old, then a booster is given at the age of 4 or 5. Some people fear the MMR vaccine may cause their child to become autistic and decide it is not worth the risk. Nearly all health care professionals throughout the world believe the MMR vaccine is completely safe.

mums

What is Mum to you?
Thursday, 22. March 2007, 08:54:55
Dear Mother:It's Thursday. It's raining hard. It's dreary outside. I woke up this morning with a sense of dread. You've been gone for 18 years. I last wrote to you 17 years ago. After we seperated, I wrote to you every day for a year, then I stopped. Today will be the day I write again.The beauty I find in a graphic designer is something I like about myself. It's the deeper part of who I am, and maybe this has something to do with you. I wasn't always like this. There is written proof in my diary, my 14-year-old mind was soaked with thoughts of teenage boys:Wednesday, April 29, 1997. I had so much fun at school. Tonight, A called again, and so did this guy named B. We talked for over an hour. He's an A+ doll. A's been mean lately. I don't know what's wrong, but I like him muchly.Friday, May 8, 1997. Tonight I had a party. There were 16 kids. It was really blasty except for the fact that C kept bothering us. One of the guys, is named D, and now I have a crush on him--he's so darling. I like A, too, but after 16 months I can't help my crushes on other guys.Reading my diary entries written, I see a picture of a self-absorbed adolescent. I read page after page hoping for some modicum of self-examination. Of course, back then, my somewhat steady boyfriend A would try to read my diary, and I do remember writing only good things in case he got his hands on it. Because I was so self-conscious that someone might find my unhappy thoughts, I occasionally wrote them on separate pieces of paper then clipped them to the diary. They were my removable truths. If A ever said, "If you love me, you'll let me read the diary," I could easily unclip these private entries.So I wonder now how much of my diary is what novelist Tim O'Brien calls "happening truth" (the indisputable reality of what happened) and how much of it is "story truth" (the personal colorized version of what happened)? Memories, with or without diaries, that supposedly record the past, are generally colorized versions of the past. That's something I've learned in spades through my work. But there I go, digressing, trying to busy myself with work matters.It's hardest for me to reread the diary entries written before you left.Nothing much happened today. Just usual stuff. Tonight my dad called and we were very happy. My mother and I had a long talk until midnight about her childhood and other things. I was really happy because we'd never been too close before, and now we were talking like we really were.And then the worst happened.Today, July 11, 1988, was the most tragic day of my life. My dearly beloved mother, whom I had just gotten to be really close with, left. Only God knows what happened. I know that life must go on and that we all must be brave. I try to tell myself that she is gone only physically and that her soul and her love remain with us. Now that she is gone, I realize how very much I love her and how hard it will be to carry on. I feel so empty inside, like I lost a big part of me. If my mother could hear me I would want her to know that she has all my love and always will.The day after you left, I began to write to you. I wrote to you every day. "Dear Mother" or "Dear Mom." Signed "Love, EeLeen" or "Lovingly, EeLeen." And sometimes "Love forever." I wrote to tell you that "you were, and still are, the kindest, most wonderful person who has ever lived."But the diary reveals that my teenage self-absorption returned. I'm embarrassed to read how few days had passed before this happened. A month had hardly gone by, and I'm telling you which boys called me that day. I even wrote to you about a New Year's Eve party I attended:December 31, 1997. Dear Mom--I was with E all night. We went to a party.. Some girl got drunk, passed out and barfed all over her date. Poor guy. At twelve, E kissed me, we were watching TV, and everyone threw streamers. It's sort of sad to leave this year behind, it was such a wonderful year for me. Goodbye, 1997! Love, EeLeen.Wonderful year? Who was I kidding? It was an awful year.From the diary, there were only a few signs of pain, of depth, and these are mostly in the removable notes. In one of them, stained by a rusted paper clip, I wrote:MY GREATEST REGRET: Many nights, such as tonight, September 23, 1997, I lie awake and think about my mother. Always, I start to cry, and my thoughts trace back to the days when she was there. She would be watching TV and ask me to come sit by her. "I'm busy now," was my usual reply. Other times, she would be in my room, and we would get in fights because she wouldn't leave. Oh, how I hate myself for that! With a little bit of kindness from her only daughter she might have been so much happier. Why wasn't I nicer to my mother, whom I loved and love more than anyone else in the world? Why wasn't I?Today, I still regret that I wasn't nicer to you, but it is not my greatest regret. It's just one of many. I see now that you left wasn't my fault. Intellectually, I do know that's true, although the 6-year-old EeLeen perhaps did not. I thought then that eventually I would get over that you left. I know today that I won't. But I've decided to accept that truth. What does it matter if I don't get over you? Who says I have to? David and Robert still tease me: "Don't say the M word or EeLeen will cry." So what if the word motheraffects me this way? Who says I have to fix this? Besides, I'm too busy.I went on to become a college student and major in graphic design, devoting my life to the study of design. I've discovered some difficult truths: namely that memory can be changed, inextricably altered, and that what we think we know, what we believe with all our hearts, is not necessarily the truth.But I am a workaholic. Why? Does it do for me what the seemingly endless collection of teenage boys did 18 years ago? Does it help me escape my painful thoughts? Does it help me feel an importance that is and was otherwise missing from my life?There is one entry in the diary, not long after you left, where the 7-year-old EeLeen wrote to you about something other than boys:Dear Mother, Dad has gotten on some "strict kick." He says I can't go out as much, darn near a flat "no beach parties," and "do some things with girls for a change." For heaven's sake, I'm looking for a husband (naturally, not quite yet) not a lesbian! Maybe I'm saying this in a moment of anger, but I feel like the one thing missing in my life is a family love and closeness. Will explain later. Lovingly, EeLeen.I never did explain later. The letters to you ended. But as I reread the past, and as I write this now, I see a connection between me then and me now. I'm learning something from her. Me then: Busy with boys, and I didn't have to think about what was missing in life. Me now: Busy with work, and I don't have to think much about what is missing in life. A family love and closeness, that's what I miss. That's what I miss about you.

colonel sanders

A native son of Kentucky, Colonel Sanders was born Jesus Harland Sanders in 1834. His parents were poor marijuana farmers in an area so remote that not a single person other than him and his parents knew that there was marijuana growing there and they never made one cent out of it. Despite having crippling poverty, he had a normal childhood, and did not gain recognition until the outbreak of the Civil War.

Sanders lived in Russia for several years during the 10's and 20's under the alias Leon Trotsky. He tried to teach that he, being God, should be the Communist leader.
Enlisting as a private in the Confederate army, Sanders was first stationed outside Richmond, VA. However, after the Union's advance past North Carolina, Confederate leader General Tso, great-great-great grandfather of actress Margaret Tso, saw the need for immediate action. He promoted Pvt. Sanders to the rank of colonel and sent him on a campaign in the north. Most notable of Col. Sander's accomplishments was his brave leadership of the Confederate forces at the Battle of Ticonderoga, where unfortunately, he lost his one and only testicle. Due to this horrible combat wound, he was ordered to develop a biological weapon to be used on the Union army. Hence, he developed his Original Recipe, which consisted of undercooked poultry, bovine colostrum, and dead Confederate soldiers. After consumption, the Union troops became violently ill, thusly allowing the Confederate army to be victorious in the battle.

Sanders leading his religion, preaching that white meat is better than dark meat
December 2005 saw the rise of the Fast Food Wars. This ferocious series of events were between the KFC ( Kentucky Fried Combatants), led by the colonel, and the McDonald MacKiddies, led by none other than Ronald McDonald. After many street battles across the USA, Colonel Sanders finally defeated Ronald McDonald in a one-on-one death match, in February 2006.

chickenbox

Chickenbox
Originally the staple food of the nouveau riche of the southern states of the USA, the popularity of the KGB Chickenbox has increased internationally over the last few decades, despite links to the spread of Bird Flu. In 1982, the Chickenbox was voted the third most popular chicken or chicken related boxed food product, in the annual International Food Review (sponsored by KGB).
5,001,960,127 chickens are consumed by the average American daily

"We Do Chickenbox Right"
Chickens are tasty. The growing numbers of chickens has become a worldwide epidemic. The United States, in its never-ending battle on The War on Children, drafted every legal & illegal Hispanic immigrant so that the CIA could kidnap their yard birds without incident.
The chickens were loaded onto trains & sent to concentration camps for interrogations. After weeks of unimaginable torture, Chicken Little confessed to the conspiracy of how the sky was falling.
President Bush ordered scientist to create a flu-like virus so that the chickens would be forced to call in sick to their jobs leading to being fired or being laid off. Bush secretly launched the biological weapon of mass destruction out of Antarctica & quickly condemned the Empire of Ice Cubes. Emperor Penguin denied any involvement.
[edit] Compact Chicken

Oprah, Rosie O'Donnell, & Rob Reiner agree with chickenbox

The Original Chickenbox
The United Nations sent out a plea to the world for someone to come up with a humane way to control the chicken population. Colonel Sanders from Kentuckistan had been raising chickens inside of boxes after he heard about the art of bonsai kittens. He told the U.N. that the chickens were in no pain & that the organization known as PETA were co-conspirators in the Grand Conspiracy. All the members of PETA were executed excluding Pamela Anderson.
Colonel Sanders called his invention the chickenbox (patent pending). He came up with the idea when he was Secretary of Defense for President Taft. President Taft required 371 chickens a day to stay alive. The problem was that the refrigerator could only hold 45 chickens. Try as he might, Colonel just could not squeeze all those chickens in there and the noise of all of them clucking in such close proximity would have been a horrendous orchestra.
In a flash of inspiration, the Colonel started to raise the baby chicks in small rectangular boxes. The ending result was that he could fit more chickens in the refrigerator. 370 to be exact. President Taft died later that day. The cause of death was lack of chicken.
[edit] An Icon is Made
Colonel Sanders decided to open a chain of restaurants & call them Kentuckistan's Gizzard Box. With chickenbox, all he had to do was place the chickenbox in the deep fryer as is and serve it to the African community. Sanders got even more creative by sticking mash potatoes, macaroni & cheese, corn on the cob, and his famous clogged-artery biscuits in the chickens’ ass to save on serving time. If it were not for Colonel Sanders, Kentucky would have remained without electricity and the populace would all look the same from the high volume of inbreeding
