Get URL Parameters Using Javascript

Get URL Parameters Using Javascript

An easy way to parse the query string in your URL to grab certain values.

Source: http://www.netlobo.com/url_query_string_javascript.htmlexpressions. Here is the function:

function gup( name )
{
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec( window.location.href );
if( results == null )
return "";
else
return results[1];
}

The way that the function is used is fairly simple. Let's say you have the following URL:
http://www.foo.com/index.html?bob=123&frank=321&tom=213#top
You want to get the value from the frank parameter so you call the javascript function as follows:

var frank_param = gup( 'frank' );

Now if you look at the frank_param variable it contains the number 321. The query string was parsed by the regular expression and the value of the frank parameter was retrieved. The function is smart in a couple of ways. For example, if you have an anchor in your URL like our example URL above does (#top) the gup() function knows to stop before the # character. Also, if a requested parameter doesn't exist in the query string then an empty string is returned instead of a null.

Dead people in social networking sites

The other day I saw my former employer's CEO's profile on linked in. The guy passed away almost two years ago due to unexpected heart attack. His profile in linked in still says he is the CEO of the company which is kind of weird. I believe those social networking sites have so many dead people's profiles in their database and those should be removed or inactivated. They should determine an inactivity timeframe or something like 2 years if there is no user activity, the account should be inactivated. Just like free email services out there like yahoo mail. I think if you don't use your yahoo email account like 2 or 3 months, it will be inactivated automatically.

MySQL Change root Password

http://www.cyberciti.biz/faq/mysql-change-root-password/

How do I change MySQL root password under Linux, FreeBSD, OpenBSD and UNIX like operating system over ssh / telnet session?

Setting up mysql password is one of the essential tasks. By default root user is MySQL admin account. Please note that the Linux / UNIX login root account for your operating system and MySQL root are different. They are separate and nothing to do with each other (indeed some admin removes root account and setup admin as mysql super user).
mysqladmin command to change root password

If you have never set a root password for MySQL, the server does not require a password at all for connecting as root. To setup root password for first time, use mysqladmin command at shell prompt as follows:

$ mysqladmin -u root password NEWPASSWORD

However, if you want to change (or update) a root password, then you need to use following command

$ mysqladmin -u root -p'oldpassword' password newpass

For example, If old password is abc, and set new password to 123456, enter:

$ mysqladmin -u root -p'abc' password '123456'

Change MySQL password for other user

To change a normal user password you need to type (let us assume you would like to change password for vivek):

$ mysqladmin -u vivek -p oldpassword password newpass

Changing MySQL root user password using MySQL sql command

This is another method. MySQL stores username and passwords in user table inside MySQL database. You can directly update password using the following method to update or change password for user vivek:

1) Login to mysql server, type following command at shell prompt:

$ mysql -u root -p

2) Use mysql database (type command at mysql> prompt):

mysql> use mysql;

3) Change password for user vivek:

mysql> update user set password=PASSWORD("NEWPASSWORD") where User='vivek';

4) Reload privileges:

mysql> flush privileges;
mysql> quit

This method you need to use while using PHP or Perl scripting.
