We were developers

Are you a computer science graduate ?

If so , here is the truth; our education in Egypt don't allow us to be a computer scientist! . i have never had the lecture that supposed to tell you "What Computer Scientists do ?" , it is supposed to be the first lecture in a reputable computer science faculty, any way forget about this lecture.

the software industry in Egypt is as follows:
  1. The Clients:  group of idiots that think you are doing the impossible or some magic for them.
  2. Software house companies:  group of idiots that have some information about the field , well you can say "dummies" not idiots , working without any standards or organized process


i don't mean that there are no reputable software companies in Egypt , there are but few. 

where is the problem? 

most of software engineers become plumbers !!, we used to develop like the plumber , he also used to plumb ! ! , we don't think before we develop . we are not working on the science any more !! , most of us googling all the day for examples !!. 

Another problem , when government created scholarships for any graduate to learn programming , they totally missed up !!!, they are teaching tooooooools not science , so you can hear some one saying "i am studding .Net right now" , what the hell is that !
  
i remembered a discussion between me and a friend , we were talking about MVC , he was telling me that MVC makes websites too slow, and there are some kind of web applications  that cant be implemented  using this design pattern , can you imagine that !!! , we were discussing a topic that was closed in the seventies.

another problem , employers don't know the right qualifications to hire a software engineer , most of the employers  are focusing on the experience  !! , big shit , experience  can be useful , but without science! , you have just hired a new plumber!

i dont mean that learning new tools is not something good, but learning based on knowledge and science is much better

There are hot topics in  science that can be useful to the business , science is created to solve problems , real life problems , guys if we didn't keep up with the science not the tool we will be obsolete and we will say

First AJAX Application

Introduction : What Is AJAX

AJAX is very interesting now a days , and a lot of developers want to know what is AJAX , AJAX stands for "Asynchronous JavaScript And XML" which means it is all about Javascript and XML.
Most of people thought that AJAX is a web programming language like PHP , ASP , .. etc. but it is not , whatever the language you are using for your web application , AJAX is totally independent.
we use AJAX when we need to do something asynchronously and don't make the page flashes. Gmail and Google Earth are a good example of AJAX.

What i need to know before i start working with AJAX ?


  1. a web programming language like PHP , ASP , JSP or whatever you want .
  2. JavaScript , and it is actually not a big deal to specify time to learn JavaScript , if you have a small programming background you can learn JavaScript from tracing others code .
  3. XML , also you won't need anytime for XML , for the simplicity sake XML let you express the data using your own tags
  4. DOM : "Document Object Model" , every element in the HTML Page is actually an object of the document , DOM actually is not a different language , you can think of it as a concept


The First Application : Sign Up Using AJAX the HTML Page < span id="Message"> </span> < from action="#" id="SignUpForm" method="POST"> Username :< input id="Form_Username" type="text" value="" /> Email:<input id="Form_Email" type="text" value=""/> Passwoed:<input id="Form_Password" type="password" value="" /> <input id="SignUpButton" onclick="return SignUp();" type="submit" value="Sign Up" /> <form> The goal of the "span" is to use it for printing the messages related to the sign up process. onClick="return SignUp();" will call the javaScript function - we will create it latter- which is responsible to send the request asynchronously The PHP Page
<?php
// SignUp.php
$UserName = $_REQUEST["Form_Username"];
$Password= $_REQUEST["Form_Password"];
$Email=$_REQUEST["Form_Email"]
$Connect= mysql_connect("localhost","root","password");
mysql_select_db("database");
$SQL = "insert into users 
set 
user_name = '$Username',
user_password= '$Password';                                                  
user_email='$Email'; "
$Query = mysql_query($SQL) 
if( mysql_affected_rows() ==1) 

echo "1"; //user added successfully else

echo "0" // //failed

?>
as you see you have to organize your code in a way that only the intended function will respond and print a text that should be displayed Now The JavaScript Part
function XMLHTTPRequest()
{
var xhr=false;
// if running Internet Explorer
if(window.XMLHttpRequest)
{
try
{
xhr= new XMLHttpRequest();
}
catch (e)
{
xhr= false;
}
}
// if running Mozilla or other browsers
else
{
try
{
xhr = new ActiveXObject("Microsoft.XMLHTTP");  
}
catch (e)
{
xhr = false;
}
}
return xhr;
}
function SignUp()
{
var Username=document.getElementById("Form_Username");
var Password=document.getElementById("Form_Password");
var Email=document.getElementById("Form_Email");
var Xml=new XMLHTTPRequest(); 
if (xhr){
var Link=" SignUp.php";
xhr.open("GET",Link,true);
xhr.onreadystatechange = function () { CheckState(xhr);};
xhr.send(null);
}else
return true;
}
function CheckState(xhr)
{
var Message=document.getElementById("Status");
Message.innerHTML="";
if (xhr.readyState == 1)
{
Message.innerHTML="Loading , Please Wait";
}
if (xhr.readyState == 4)
{
if (xhr.status == 200)
{
if(hr.responseText=="1")
Message.innerHTML="User Added";
}
else
{
Message.innerHTML="Error occurred";
}
}
}

Eminem Recovery

Eminem is not kidding ! , this guy writes almost all of his songs , in some way the song touches you, The last album Eminem released is recovery! , you can't say anything but wow , the most interesting thing in Eminem is that he can choose his topics , he is not singing bla bla bla bla love , he talks about Iraq war , bad relationships with his mother , recover from addiction ,careers effect on the family ,  ...etc.

i hope that in Egypt we can find something that is similar to Eminem , Ahmed Mekky is a great start in the Arabic rap , also MTM is trying. i don't want to hear Arabic songs talking about loooooove  any more  , for god sake life is not about love only !! , video clips sucks , a lot of sexuality content nothing interested !!!! ,

there is also a light of hope like hamza numera , maher zain , sami youssef , and even black theama.

Amr Diab "The Montain" is not telling us any useful shit! , he is working on his muscle more than he works on his songs, the same thing for tamer hosni , they killed all the topics of love songs , their religious songs suck , you simply cant feel any thing while they are signing , the melody and the lyrics can meet in hell !!! ,  bad lyrics and bad melody and they are not serving the song at all



here is a list of songs that i recommend you to hear :


1- i love the way you lie - Recovery
2- i'am not afraid - Recovery
3- Space Bound - Recovery
4- when i am gone -  Curtain Call: The Hits

Listen and Enjoy

Rihab City is not what you think !

a couple of friends visited me in rehab , they came to have a walk and "sohor" , we were celebrating Ramadan days, they told me that Ramadan hasn't come yet to rehab , people is not giving a shit about any religious activities, actually i was sad because i looked at the people and i felt so shame ! what happened ?! is this the end!

my friends left , and it was too late and there wasn't much time till "fajar" so i decided to pray in the mosque . guess what ! it was like a Friday prayer ! , the mosque is almost full ,and there was competition in the mosque about remembering the last six discussed "hadeth" , the winner was a kid ! , did you believe we still have good people , the good will remain in this nation till The Day of Resurrection.

Start be your self first and every thing will change , we should keep trying till the last drop of our blood ,   people don't lose hope please, and please before making any judgments be sure that you can the see the things from more than one point of view

Respect

well, this is my first article in the blog and it is not even technical, but it is an important thing; most of us forgot it.

Respect definition according to wikipedia is : denotes both a positive feeling of esteem for a person or other entity (such as a nation or a religion), and also specific actions and conduct representative of that esteem. Respect can be a specific feeling of regard for the actual qualities of the one respected (e.g., "I have great respect for her judgment"). It can also be conduct in accord with a specific ethic of respect. Rude conduct is usually considered to indicate a lack of respect, disrespect, whereas actions that honor somebody or something indicate respect.
 in these days we are judging people on their look , money they have , what kind of car they are driving ,.... bla bla bla. we missed the core of people , why we cant simply respect anyone poor , rich , cute , ugly , whatever his/her religion ,...?

the reason behind this article that i have found a lot of people which are good persons but not treated well ,  in Egypt some of us forgot what they were before , we lost our identity , we don't know if we are Africans or Arabians or what !


prophet Mohammed peace upon him said " there are no differences between people except in piety", really amazing , we knew that along time before but as i told you we forgot a lot of things , jascues chriac said "every one has something to say , so listen carefully"


Respect each other , listen to the others point of view , that is what we are missing
