Restarting

I started writing the blog again. That is not for the others but, for myself. Writing is a path to release our emotions while improving an adorable skill. All those past years I was watching, observing and waiting. Watching at the number of selfish acts of humans, their endless competitions and dirty hands/souls. Observing how we are destroying all the beauties and values we have. Waiting for the worst future if we do not have any better diversion. Therefore, I write so that I can express what I really feel about most of the surroundings I have. If my writings would occur at least a tiny change of someones' attitude that will make my work worth enough.

What Is Lightning?

Lightning is a discharge of atmospheric electricity which is triggered by a buildup of differing charges within a cloud.

The result is a sudden release of electricity which causes a distinctive bright flare, followed by a thunderclap.

Lightning is most common around the equatorial regions of the world, although it can potentially strike anywhere, and it appears in a variety of guises, depending on atmospheric conditions.

What is Bioinformatics?

Bioinformatics is the use of computational methods to study biological data.

Bioinformatics is:

1. the development of computational methods for studying the structure, function, and evolution of genes, proteins, and whole genomes;
2. the development of methods for the management and analysis of biological information arising from genomics and high-throughput experiments.

Some references that would be useful:

• Paul G. Higgs and Teresa K. Attwood, Bioinformatics and Molecular Evolution
• Arthur M. Lesk, Introduction to Bioinformatics

AJAX

Ajax is something interesting and also the new trend. It is not another programming language but, a way to change the content of a web page without reloading it. JavaScript contains some objects relevant to working with AJAX.
ajax.js
function getXMLHttp()
{
var xmlHttp

try
{
//Firefox, Opera 8.0+, Safari
xmlHttp = new XMLHttpRequest();
}
catch(e)
{
//Internet Explorer
try
{
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e)
{
try
{
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e)
{
alert("Your browser does not support AJAX!")
return false;
}
}
}
return xmlHttp;
}
function MakeRequest()
{
var xmlHttp = getXMLHttp();

xmlHttp.onreadystatechange = function()
{
if(xmlHttp.readyState == 4)
{
HandleResponse(xmlHttp.responseText);
}
}

xmlHttp.open("GET", "ex1.php", true);
xmlHttp.send(null);
}


function HandleResponse(response)
{
document.getElementById('ResponseDiv').innerHTML = response;
}
