FLY TO THE ZENITH OF SUCCESS

Today onwards I am willing to write series of articles about various programming languages. As a programmer we should compare all the programming languages, study its advantage and disadvantages . By these we can consult a correct platform for our clients and we can plug in this in appropriate situation. So advantages and disadvantages over the programming languages again converted for an advantages for the client.

First upon we discuss about programming languages.

A program is list of instructions that perform a particular task or algorithms. A programming language is a machine understandable artificial language that used to write the programs. All programming languages have its own syntax and semantics.

Programming must follow some methodology in programming .

During the year 70s and 80s, the primary software engineering methodology was structured programming. The structured programming approach to program design was based on the following methods:

* To solve a large problem, break down the problem into several pieces and work on each piece separately;
* to solve each piece, treat it as a new problem that can itself be broken down into smaller problems;
* repeat the process with each new piece until each can be solved directly, without further decomposition.

This approach is also called top-down program design.

The Language “C” is considered as a top Structural programming language.

The next was OOP (Object Oriented Programming):

This methodology is organized around “objects” rather than “actions” and data rather than logic. Objects is an identifiable entity with some characteristics and behavior. Object Oriented programming paradigm support the following idioms like information hiding, data abstraction, encapsulation, modularity, polymorphism, and inheritance.

The First OOP languages is “C++”. Then it enhanced by JAVA.

Aspect-oriented programming (AOP) is another programming paradigm that enhance modularity by allowing the separation of cross-cutting concerns, forming a basis for aspect-oriented software development.

These are the main programming paradigms. There is a lot of other paradigms . We will elaborate our knowledge by contributing your suggestions and information about it.

Hello All,
Yesterday i was searching for a solution to split large array into small pieces. Suddenly i noticed the that php have a built in function to split array into small pieces. It was very surprise to me ..
Here it is
Function : array array_chunk ( array $input , int $size [, bool $preserve_keys= false ] )

< ?php
$input_array = array('a', 'b', 'c', 'd', 'e');
print_r(array_chunk($input_array, 2));
print_r(array_chunk($input_array, 2, true));
?>

The output will be like this : -

Array
(
[0] => Array
(
[0] => a
[1] => b
)

[1] => Array
(
[0] => c
[1] => d
)

[2] => Array
(
[0] => e
)

)
Array
(
[0] => Array
(
[0] => a
[1] => b
)

[1] => Array
(
[2] => c
[3] => d
)

[2] => Array
(
[4] => e
)

)

Have fun Cheers

Here is the PHP function to calculated duration of “wav” or “GSM” files

First we open file using fopen. After we calculate the size of that file (inbytes) using filesize().

Then we unpack the audio File .

unpack(’vtype/vchannels/Vsamplerate/Vbytespersec/valignment/vbits’,$rawheader);

This will return following array

Array (
[type] => 1
[channels] => 2
[samplerate] => 44100
[bytespersec] => 176400
[alignment] => 4 [bits] => 16 )

from this array we get bytepersec.

Now it is very easy to find out the duration.. !!

$size_in_bytes/bytespersec.

Code is here.

public static function getDuration($file) {

$fp = fopen($file, ‘r’);
$size_in_bytes = filesize($file);
fseek($fp, 20);
$rawheader = fread($fp, 16);
$header = unpack(’vtype/vchannels/Vsamplerate/Vbytespersec/valignment/vbits’,
$rawheader);
$sec = ceil($size_in_bytes/$header['bytespersec']);
return $sec;

}

Have fun.

Today is a special day for me, Because i have completed 1 year in ventures unlimited solutions. Last one year i gone through number of incidents and various experiments. My achievements in the last one year is very much important to me.
in first of last year i studied symfony frame work, I love this framework as well , because we don’t want to write complete code for the project, Lazy folks never
like coding from the scratch. So really i love it, it is fully on MVC architecture. MVC was also familiar to me though J2EE and Struts,
After that i have developed some platform for mobile VAS like bulk sms , shortcode , mobile to bulk sms customized applications, SMPP Protocols. REST Services,
In betweenthis i studied network and wireless configurations

I have been participated in the project cycle for an online examination software. It was my big project. A lot of modules in it. frankly speaking i have been
touch with each and every modules in it. faced a lot of problems .. with ajax (asynchronous calls, security issues and more ). Actually it given good exposure to me .

Next was on telephony domain . That is vUvOice. It was a great exposure to me . Because no one get such a situation to study this. Actually we decided to work on this domain because of freshness of this domain.
Our company policy is to take risk on various domain and achieve the goal by making solutions for the realtime situation. I think our company is the first one working on this domain in India.
I’m telling about asterisk… !!! The open PBX software used for soft switching, IVR solutio.

Before here i worked in LogicManse Solution And Technologies . From there i studied J2EE struts etc

This a true story of mine. I brought a Lenovo 3000N200 series laptop one year back, exactly 21’st Feb 2008 from Dubai Shopping festival for Rs 35, 000. I was very satisfied with their product initially, as it is cost effective with good performance. But after 3 months of working my laptop charger burnt out. I called up the customer care (18004252666) asking for the replacement and they said because it is burnt, they can’t replace it. For me, living without laptop and internet is worst thing in my life.
