Demo:Check the demo
URL:http://valums.com/ajax-upload/
Download:Download the source code

Usage:

Download the script, unzip to a folder; let’s say ajax-upload-script in your root folder.

For me, its http://localhost/ajax-upload-script such that folders server,client, tests will be in your folder ajax-upload-script

Create a new file; let’s say upload.php in your ajax-upload-script folder.

Include fileuploader.js and fileuploader.css into upload.php

The required two files are in your ajax-upload-script/client folder.

<script src="client/fileuploader.js" language="javascript1.1"></script>
<link href="client/fileuploader.css" rel="stylesheet" type="text/css" media="all" />

Now create a container element on the page, which accepts the files, we drop to it.

  <div id="file-uploader">
        <noscript>
            <p>Please enable JavaScript to use file uploader.</p>
            <!-- or put a simple form for upload here -->
        </noscript>
    </div>

Now initialize your uploader. Paste the below the javascript below the container div tag.

 <script>
        function createUploader(){
            var uploader = new qq.FileUploader({
                //  pass the dom node (ex. $(selector)[0] for jQuery users)
                element: document.getElementById('file-uploader'),
               // path to server-side upload script. In our case server/php.php
               action: 'server/php.php'
            });
        }
        window.onload = createUploader;
    </script>

Pass the DOM node to the element, and the server side script path to the action.
This script comes with sever side script also, to upload files, in different platforms-PHP, Coldfusion, CGI and Java.

We will take the PHP file, php.php in server folder as our server side script to upload files.
You can delete the other platform files in this folder, no harm at all.

That’s all. Our Ajax multiple file upload script with progress bar, drag and drop is completed. Just open the file in browser http://localhost/ajax-upload-script/upload.php
You can upload the files by clicking the ‘Upload a File’ button or simply dragging and dropping files on it. Files will be uploaded to server/uploads folder.

Some test files and demos are there in tests folder. If you want to play with this script further, have a look into it. If not, you can simply delete it.

You can use jQuery also with this script, and other settings such as allowed extensions, file size limits and events.

    // additional data to send, name-value pairs
    params: {},

    // validation
    // ex. ['jpg', 'jpeg', 'png', 'gif'] or []
    allowedExtensions: [],
    // each file size limit in bytes
    // this option isn't supported in all browsers
    sizeLimit: 0, // max size
    minSizeLimit: 0, // min size

    // set to true to output server response to console
    debug: false,

    // events
    // you can return false to abort submit
    onSubmit: function(id, fileName){},
    onProgress: function(id, fileName, loaded, total){},
    onComplete: function(id, fileName, responseJSON){},
    onCancel: function(id, fileName){},

    messages: {
        // error messages, see qq.FileUploaderBasic for content
    },
    showMessage: function(message){ alert(message); }        

To Use with jQuery:

Include jQuery javascript into your page.

<script src="http://code.jquery.com/jquery-1.4.4.min.js" type="text/javascript"></script>

And replace the script below container DIV with this.

    jQuery(function(){
        var uploader = new qq.FileUploader({
            element: document.getElementById('file-uploader'),
          // url of the server-side upload script, should be on the same domain
	action: 'server/php.php',

        }); 

    });

The baby boy came out in morning @ 07:15am. I am on the way to hospital from Hyderabad and exactly at Vijayawada Kanakaduragamma Temple.

Jumped out from the dead slow RTC bus in bus stand and catched an auto and reached hospital, and ran into the hospital, calling my mother on her mobile.

My boy is on the table in my mother hands, and waiting for a first clean up from nurse.

My mother is so happy and saying that her son became father!!!

I am quite calm and watching him… Nurse came and taken him into her hands and cleaned with him with little hot water. Me and My mother noticed a cut on his head. as he came out after sizerian.

He is so cute and quite calm. a lot is happening with him, in life.

php 5

The final release of PHP 5 was announced on 13 July 2004.(as per php.net news archives)

Some of the key features of PHP 5 include:

• The Zend Engine II with a new object model and dozens of new features.
• XML support has been completely redone in PHP 5, all extensions are now focused around the excellent libxml2 library (http://www.xmlsoft.org/).
• A new SimpleXML extension for easily accessing and manipulating XML as PHP objects. It can also interface with the DOM extension and vice-versa.
• A brand new built-in SOAP extension for interoperability with Web Services.
• A new MySQL extension named MySQLi for developers using MySQL 4.1 and later. This new extension includes an object-oriented interface in addition to a traditional interface; as well as support for many of MySQL’s new features, such as prepared statements.
• SQLite has been bundled with PHP. For more information on SQLite, please visit their website.
• Streams have been greatly improved, including the ability to access low-level socket operations on streams.

ISRO loses communication with chandrayaan-1

The Radio communication with Chandrayaan-1 was abruptly lost after friday (28 Aug 2009 ) midnight at 0130 Hrs (IST) on Saturday. ISRO scientists are reviewing the telemetry data received from the spacecraft before losing communication to analyse the health of sub-systems of spacecraft.

AS per earlier news for ISRO, though Chandrayaan-1 has achieved 90 per cent of his task and there is no major worry as such..this is a serious one. and they are working hard to rectify the problem.

About Chandrayaan-1:

Chandrayaan-1 spacecraft was launched from Satish Dhawan Space Centre in Sriharikota on October 22, 2008 .The Spacecraft has completed 312 days in orbit making more than 3400 orbits around the Moon and providing large volume of data from sophisticated sensors like Terrain Mapping Camera, Hyper-spectral Imager, Moon Mineralogy Mapper etc., meeting most of the scientific objectives of the mission.

Second time in its life:

This is the second time that chandrayaan is running into trouble. month back it developed a snag when it lost one of its sensors which forced ISRO to push its orbit from 100 kilometers to 200 kilometers from the moon’s surface. The change in orbit meant the data would be of lower quality.

Love in mathematics

Are you passionate about Mathematics and programming ? Like to play with numbers and find the magic in them? if so, soon you will be addictive to Project Euler, a must site for mathematics lovers.

What is Project Euler?

Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.

How to use Project Euler:

Just Register with Project Euler website, and you are ready to sink in maths.

After successful registration and login, you are greeted with 252 problems(Number of problems might change as new problems are added frequently.

Solutions to some of the problems can be get by paper and pen applying simple mathematics formula learned at school. Some can be solved only with advanced mathematics upon a lot of thinking thinking thinking and writing algorithms but most of then requires some programming in your favorite language.

When you got the solution, you can enter the answer there and check whether you are right or not? If you are right, particular problem will be shifted to ‘solved problems’ sections and you are ranked +1.  And score board will show the levels of all users based on the number of problems solved. The more problems solved -> more score -> more respect at forum.

And, if you solve the problem, then only you will be able to see the forum for that particular problem, where all other share their code and mathematical formula they used to solve the problem.

A Problem from Project Euler:

problem 2 project euler

and if you cant solve the problem…??? Project Euler says…

Please do not contact Project Euler if you are unable to solve a particular problem. If you can’t solve it, then you can’t solve it!

Dont worry! I try to post solutions to problems here on my blog.

so, Happy Mathematics.

What’s to come in 2009

I cant say anything right now, but 2009 will have more dynamic stuff here than 2008.

I am on web for last 10 years and blogging for last 3 years(rarely), and got something to share with you and need to learn a lot from WWW. so lets start.

Arjun Says:

I am Arjun, I have attended the Power grid interview on 3-Nov-2008 at Bhubaneshwar. I like to share some of the questions that I have faced in the interview.

The Interview panel comprises a team of 6 persons, as this interview is for the post of AE to work under Rural Electrification projects in the states of West Bengal and Orissa, apart from the Technical skills they looked for knowledge in Hindi also. As the work comprises mostly of construction of Distribution sub-statation and Distribution of the supply. They very much concentrated on the Power systems and they also posed questions in the Power Electronics.

On an average the interview will go around half-an-hour as said earlier they looking for both Hindi and Technical skills in the Candidate. I am posting some questions here which I have faced in the interview. Hope it will be useful for the people who are atteninding the interviews.

1) What is a Triode? What are its uses?
2) What is a Triac?
3) What is a Thyristor?
4) What is the HVDC Transmission System?
5) What are the conditions applicable to lay an HVDC Line?
6) Does Conveter and Inveter has same ckt? Explain.
7) Why do we use only Sinusoidal Wave in AC supply why not the Square,Triangle or Sawtooth etc?
What constraints regarding the HVDC Transmission System?
9) Explain the Local Distribution System?
10) What are the different types of transformers present in the Transmission and Distribution system?
11) How would you supply a single house hold load from a 3-phase supply coming out of a sub-station?
12) How would you supply power to a village which is very far from a sub-station and has only a 11kV line running near by?
13) What are the important structures of a local Distribution System?
14) Name any Five Major Rivers of country?( we should answer in Hindi)
15) Name the Person who became President of India from A.P?(In Hindi)
16) Name the Person who became P.M of India form A.P? (In Hindi)
17) Name the Famous Power Plants present in A.P? (In Hindi)
18) Are you willing to work in the rural Areas of Orissa?

They may ask question on your native place,name,college etc., to test our language skills and confidence levels in answering it.

Thank you Raju for giving  me this oppurtunity, hope in future I can contribute more for this site.

Regards,
Arjun

GoDaddy

for long time,  I am waiting for raju.com and settled with raju.net.in at last. Last evening, I came to know that .me registrations are going started in a couple of hours and waited till the time to start and grabbed myself raju.me by paying $39.98/2 years.

.ME Domain Registration

Before that I looked does this domain available or not at www.domain.me oops.. again I was unlucky. that was not available. But godaddy says that was available and registered for me after some lengthy confusing pages. GoDaddy doamin registration pages were very confusing and very much  irritating.

I got confirmation mail from goDaddy saying that my order was successful. Still, I can’t believe that as I already know that raju.me was already registered by someone. I keep trying to refresh whois records for raju.me and nothing was changed. how it would be?   After 30min, I got another mail from GoDaddy saying that the order can’t be completed as it was already registered. OMG, Don’t they know it before processing my request.

anyhow, raju.net.in was quite good domain name. and now, I am not at all waiting for another domain name by name Raju, but for my amount I paid to goDaddy.
