At the 1994 annual awards dinner given for Forensic Science, AAFS President Dr Don Harper Mills astounded his audience with the legal complications of a bizarre death.
Here is the Case:
On March 23, 1994 the medical examiner viewed the body of Ronald Opus and concluded that he died from a shotgun wound to the head.
Mr. Opus had jumped from the top of a ten-story building intending to commit suicide. He left a note to the effect indicating his despondency .As he fell past the ninth floor his life was interrupted by a shotgun blast passing through a window, which killed him instantly.
Neither the shooter nor the deceased was aware that a safety net had been installed just below the eighth floor level to protect some building workers and that Ronald Opus would not have been able to complete his suicide the way he had planned.
“Ordinarily,” Dr Mills continued, “A person, who sets out to commit suicide and ultimately succeeds, even though the mechanism might not be what he intended, is still defined as committing suicide.” That Mr. Opus was shot on the way to certain death, but probably would not have been successful because of the safety net, caused the medical examiner to feel that he had a homicide on his hands.
In the room on the ninth floor, where the shotgun blast emanated, was occupied by an elderly man and his wife. They were arguing vigorously and he was threatening her with a shotgun.
The man was so upset that when he pulled the trigger he completely missed his wife and the pellets went through the window striking Mr. Opus. When one intends to kill subject “A” but kills subject “B” in the attempt, one is guilty of the murder of subject “B”.
When confronted with the murder charge the old man and his wife were both adamant and both said that they thought the shotgun was u nloaded. The old man said it was a long-standing habit to threaten his wife with the unloaded shotgun. He had no intention to murder her.
Therefore the killing of Mr. Opus appeared to be an accident; that is, if the gun had been accidentally loaded. The continuing investigation turned up a witness who saw the old couple’s son load ing the shotgun about six weeks prior to the fatal accident.
It transpired that the old lady had cut off her son’s financial support and the son, knowing the propensity of his father to use the shotgun threateningly, loaded the gun with the expectation that his father would shoot his mother.Since the loader of the gun was aware of this, he was guilty of the murder even though he didn’t actually pull the trigger. The case now becomes one of murder on the part of the son for the death of Ronald Opus.
Now comes the exquisite twist. Further investigation revealed hat the son was, in fact, Ronald Opus. He had become increasingly despondent over the failure of his attempt to engineer his mother’s murder. This led him to jump off the ten-story building on March 23rd, only to be killed by a shotgun blast passing through the ninth story window. The son had actually Murdered himself, so the medical examiner closed the case as a suicide

101. Sound is sent from the radio station through the air to your radio by means of electromagnetic waves. News, music, Bible teaching, baseball games, plays,
advertisements- these sounds are all converted into electromagnetic waves (radio waves) before they reach your radio and your ears.
102. At the radio station, the announcer speaks into a microphone. The microphone changes the sound of his voice into an electrical signal. This signal is weak
and can’t travel very far, so it’s sent to a transmitter. The transmitter mixes the signal with some strong radio signals called carrier waves. These waves are
then sent out through a special antenna at the speed of light! They reach the antenna of your radio. Your antenna “catches” the signal, and the radio’s
amplifier strengthens the signal and sends it to the speakers. The speakers vibrate, and your ears pick up the vibrations and your brain translates them into
the voice of the radio announcer back at the station. When you consider all the places the announcer’s voice travels
103. Every radio station has its own frequency. When you turn the tuning knob on your radio, you are choosing which frequency you want your antenna to “catch.”

scream, and snarl, but they cannot roar.
106. They can jump a distance of 30 feet, and jump as high as 15 feet. It would take quite a fence to keep a mountain lion out!
107. Their favorite food is deer, but they’ll eat other critters as well. They hunt alone, not in packs like wolves. They sneak up on their prey just like a
house cat sneaks up on a bird or toy- one slow step at a time. A lion can eat ten pounds of meat at one time! That’s equivalent to 40 quarter-ponder hamburgers!
108. Queen ants can live to be 30 years old
109. Dragonflies can flap their wings 28 times per second and they can fly up to 60 miles per hour

such as Christian stations that have Bible stories and sermons; sports stations that broadcast live baseball and football games; and stations that specialize
in news programs and “talk shows,” where listeners call the station and discuss various topics. FM is used mostly for stations that specialize in music.

Here is a tutorial which will explain how to pass Javascript variables to Php.This tutorial works only for files under the same server
Aim:To pass document.referrer variable to Php and to write the referrer variable on a text file;
First let us create two file called 1a.html and 2a.html
1a.html will contain a link to 2a.html
and 2a.html will contain just two javascript calls one will call a file called xml1.js
Here is the source of 1a.html
<a href=’http://www.ramanean.com/java/2a.html’>2</a>
Source of 2a.html
<html>
<head>
</head>
<body>
<script src=”xml1.js”></script>
<script type=”text/javascript”>
change1();
</script>
Here First we are calling xml.js javascript and then calling change1() function in it
Source of xml1.js
var xmlHttp
function change1()
{
xmlHttp=GetXmlHttpObject();
if (xmlHttp==null)
{

{
xmlHttp=new ActiveXObject(”Msxml2.XMLHTTP”);
}
catch (e)
{
xmlHttp=new ActiveXObject(”Microsoft.XMLHTTP”);
}
}
return xmlHttp;
}
In the above function function GetXmlHttpObject() is nothing but creating Xmlhttpobject by which get function will be routed (AJAX).Do n’t worry about that if you need to more about there go to http://www.w3schools.com/ajax/ajax_source.asp.
Now let us go to the second line ,Here we are declaring change1 function and then we checking whether browser supports xml if not browser will display an error message indicating that “your Browser does n’t support AJAX”
Now let me explain what these four lines contain
The php file is like this
<?php
$q=$_GET[”q”];//Getting the javascript variable
$file=file_put_contents(’ip1.txt’,$q);//writing the variable to file
?>
by this you can pass variables to a php script and from php you can insert any data into your database;
URL Error (23000148): An error has occured while trying to browse through the proxy.
Failed to connect to the specified host. Possible problems are that the server was not found, the connection timed out, or the connection refused by the host. Try connecting again and check if the address is correct.
If this error occurs in your proxy or web server.Just Restart the web server.This would solve any problems.This error occurs due to network problems in the connection port.
From Today onwards , I have decided to learn javascript which is a widely used language in web scripting ,now days it is hard to find a webpage without javascript.
A little about Javascript from wikipedia:
JavaScript is a scripting language most often used for client-side web development. It was the originating dialect of the ECMAScript standard. As such, it is a dynamic, weakly typed, prototype-based language with first-class functions.
JavaScript was influenced by many languages and was designed to have a similar look to Java, but be easier for non-programmers to work with.[1] The language is best known for its use in websites (as client-side JavaScript), but is also used to enable scripting access to objects embedded in other applications (for example Microsoft Gadgets in Windows Vista Sidebar).
And also most people often confuse javascript with java but in real time javascript is entirely unrelated to java.Also we can say that Javascript is independent of java.
Another advantageis that we can use javascript with any programming language provided the user’s browser has enabled javascripts
