I adopted a new home and created a website for it.  Check it out here: Palayan City

<?php
$result = exec('traceroute ' . $_SERVER["REMOTE_ADDR"], $lines);
echo '<h1>Your IP is ' . $_SERVER["REMOTE_ADDR"] . '</h1>';
echo '<pre>';
foreach ($lines as $n => $line) {
	if ($n) echo '<br />';
	echo $line;
}
echo '</pre>';
echo '<p>-end-</p>';

Here’s how the resulting page looks like: reverse-traceroute.php

$ iconv --from-code=ISO-8859-1 --to-code=UTF-8 latin1.txt > utf8.txt

or simply

$ iconv -f ISO-8859-1 -t UTF-8 latin1.txt > utf8.txt

$ iconv -t ISO-8859-1 -f UTF-8 inputfile > outputfile

RedirectMatch 301 (.*)$ http://www.newdomainhere.com$1

Save this into .htaccess and upload on the root directory on your old domain.

To start with an AUTO_INCREMENT value other than 1, you can set that value with CREATE TABLE or ALTER TABLE, like this:

mysql> ALTER TABLE tbl AUTO_INCREMENT = 100;

As a programmer, I’ve been using find to locate string in my source code.  Issuing a find would include svn files too which is not my intension.  Here’s the command:

$ find . -not -regex '.*svn.*' -exec grep "$1" '{}' \; -print

ALTER TABLE `attributes` DROP FOREIGN KEY `attributes_ibfk_1`;

MySQL ERROR 1005 (HY000): Can’t create table ‘Table.frm’ (errno: 150).  Here’s the solution.

Example:
ALTER TABLE `race` DROP FOREIGN KEY `race_ibfk_1`;

ALTER TABLE `race`
ADD CONSTRAINT `race_ibfk_1` FOREIGN KEY (`specieId`) REFERENCES `specie` (`specieId`) ON DELETE CASCADE;

$ sudo mount -o loop /path/to/feisty-desktop-i386.iso /tmp/ubuntu-livecd

This command will replace all instances of ‘replaceme’ with ‘newstring’ in files ‘*.php’ on /home/mysite/httpdocs.

find /home/mysite/httpdocs -name '*.php' | xargs replace 'replaceme' 'newstring' --

1. Use OpenDNS free services by adding 208.67.222.222 and 208.67.220.220 on your /etc/resolv.conf.
2. Go to http://www.opendns.com/support/cache/ then enter the website address.
