A tracking log is typically a file where a computer program, such as a web server, stores the behaviour of each user through several records. In the case of a web server, there is one record in the tracking log per each file served.
E.g. (simplified Apache log record):
IP adress: 127.0.0.1
User: root
Time: [10/Jun/2010:22:30:56 +0200]
Type:GET
Web page: /phpmyadmin/db_structure.php
Protocol: HTTP/1.1

What is the difference between sticky and retroactive comment signatures?
Retroactive changes your signature on every message you've ever posted.
Sticky keeps your old signatures and only uses your new signature for any subsequent messages. It should be noted that sticky signatures are removed if you later choose retroactive signatures.
What is it called when text can be converted into a table by using the convert text to table option?
Using a text processor (such as Microsoft Word) you can convert between text and table formats. You will rarely have to make it.
The columns in a "text formatted" table are separated just by tab spaces, as if using TAB key.
This tool allows to represent text with less complexinternal formatting, just using tabs to separate each cell of each column of a table.
The internal formatting complexity may be a concern when you have to worry about compatibility between different programs, like Microsoft Word and simpler text editors, such as Windows Notepad or even with some old fashioned Internet browsers.
Videos can be uploaded to a variety of user-based websites such as Youtube, Facebook, Myspace, or Flickr.

How do you populate values of combobox using server side scripting as php?
I am assuming you already have a mysql connection function/string in place
Now select the database
mysql_select_db("db_name"); // Put the name of your database in place of db_name
// Add the column you want data from in place of ID
// Add the name of your table in place of table_name
$query = mysql_query("SELECT ID FROM table_name");
// This gets a bit complicated but it helps with debugging
?>
while($result = mysql_fetch_array($query))
{
$value = $result['ID'];
?>
}
?>
If you want value of another combobox by selecting a combobox then use of AJAX is helpful

How do you access private variable in flex?
In Flex, you access a private variable by calling it from within that class. Remember, the "private" modifier means it cannot be directly accessed outside of the class you declare it in (note I say "directly accessed" you can indirectly access it via public functions which I will show below).
Example:
declare your variable at the top of your class like this:
private var myVariable:String;
Then, inside one of your functions of that class, you can access the variable and/or assign it this way:
public function changeMyVariable(value:String):void {
// sets the private variable to a custom string
myVariable="test String";
trace("myVariable is set to "+myVariable);
// sets the private variable to the argument passed in
myVariable = value;
trace("myVariable is now set to" +myVariable);
}
How do you change a website that someone else built if you are a beginner?
Well first of all if your asking this question then im going to have to first say you should'nt be trying to change sombody elses website if you dont first know how to build your own websites. Then I'm going to add that you can only pull HTML and Javascript off the net... Either way you need to know HTML, If the website is written in somthing such as PHP your going to need the original sourcecode before you can make modifications. You can get the HTML in Mozilla by clicking View > Page Source or in Internet Explorer by View > Source. But to know what your doing you need to know atleast some HTML or well... Your just gonna see a bunch of random tags and have no idea whats doing what.
Now if your trying to change a PHP or ASP, etc website and you have got a copy of the source code then well just throw it into Notepad or Notepad++ (whichever you wish to use... theres tonnes of editing software such as Dreamweaver or Frount Page) and make your changes, If you have the technical documentation then that just makes things easier right. If your pulling HTML off the net (Watch out for copyrights) then you can do a simple copy and paste or a Save as and then edit the data as you wish.
Now that you have your website and you've changed what you wish its time to put it all on the net for all to see. Now if your sitting at the server then you can simply copy the files into the servers home directory (example servers are Apachi or IIS). If your at a remote location files can be uploaded to the server via protocols such as FTP or Telnet, etc.
This cannot be done. If I wish to visit xyz.com and copy their HTML, Edit it and put it back up. This is legally not possible and can only be done by people that know what they are doing. If you read this question hoping to learn how to hack into a system and change their web page then its already obvious you don't have the required skills. Sure there are ways to do it but they all seem to land you in A LOT of trouble. DON'T TRY.

An empty tag is a tag that contains no element or attributes. For example:
The bold is the element and the italic is the attribute. An empty tag doesn't contain either, and rather than an opening and a closing tag, it is just one tag, for example:
I got banned for 24 hours from kinz chat plus but it was over 24 hours so can I get help?
I got banned from kinz chat plus on my kangaroo's acount for 24 hours also, (from a fake report) and the next day it let me on. But ever since then, it always says, "kinz chat plus is closed in this color zone at this time. Please check the scedule to see when kinz chat plus will be open." when I was on an open color zone. Or it would say, "You are unable to enter kinz chat plus at this time. You have received a kinz post letter explaining this. You will not be able to enter kinz chat plus until 1/8/36", when I never got a kinz letter about it. Sorry to say, but, I don't think you'll be entering kinz chat plus anymore.
An XML attribute is a specified property for a tag with a value. For example, the XML tag "person" could have the attribute "name" with a value of "bob."

Void is a keyword in Java. It is always used in method declarations. When used in the line that declares a method, it signifies the fact that the method will not return any value. The JVM will not expect the method to return anything.
Ex: public static void main(String[] args) {}
What is the easiest CMS to learn and to use for non-tech people?
As with most things, the true answer is "It depends", based on what the user needs. However, assuming the user needs a basic brochure-type site that he or she can easily edit and add new pages/sections to, then I'd have to go with CMS Made Simple
If the user is only interested in blogging, then WordPress is the easiest blog system to use.
There are certainly other systems that could compete for the title of "easiest", but it really is subjective and difficult to make a blanket statement suitable for every user and every project, so I have chosen the two that I think will fit best for most situations and most non-tech users.
What is a request object in asp technology?

What is the difference between the ol and ul tags?
OL stands for an Ordered List whereas UL Stands for an un-ordered list
Let us say you have a code like below
<ol>
<li>AAA</li>
<li>BBB</li>
<li>CCC</li>
</ol>
<ul>
<li>AAA</li>
<li>BBB</li>
<li>CCC</li>
</ul>
The output would be
# AAA # BBB # CCC and
* AAA * BBB * CCC Ordered lists give a numbering for the list elements while an un-ordered list would give bullets.
