PHP Speedy is a PHP script by aciddrop.com that can increase your web site loading time by as much as 500%.

The key to this decrease in loading time is “making fewer HTTP requests, adding a far-future expires header, gzipping your page’s components, and minifying your JavaScript, CSS and HTML”. PHP Speedy accomplishes all of these techniques.

Now, there is also a PHP Speedy Wordpress plugin available. It would be interesting to see a comparison between PHP Speedy and WP Super Cache.

Personally, I haven’t tested PHP Speedy, but it looks promising. Let me know if you have tried PHP Speedy and what your results are.

Nothing is worse than entering repetitive, monotonous commands into a router to accomplish a simple task. By using PHPTelnet we can create a script that will make use of a web form to provision (create pvc or a Private Virtual Circuit) DSL customers in a Cisco router. The script will also write to a log file for security and troubleshooting purposes. This script could be used for many other tasks as well as it is very easy to modify.

NOTE: Depending on your setup, you may need to make modifications to the script.

First, I will focus on the PHP script, and then the web form.

The first part of the script will call in the PHPTelnet.php file. And grab the variables from our web form with the POST method.

require_once "PHPTelnet.php";

$telnet = new PHPTelnet();

$vpi = $_POST['VPI'];
$vci = $_POST['VCI'];
$spd = $_POST['SPD'];

This next section deals with logging the requests to a file named ‘log.txt’. Make sure you manually create the file first.

//Log actions to file
$logfile="log.txt";
$fh = fopen($logfile, 'a') or die("ERROR: can't open file");
$stringData = $_SERVER['REMOTE_ADDR']." added ".$vpi."/".$vci." ".date("m-d-y.h:i")."\n";
fwrite($fh, $stringData);
fclose($fh);

Initiate the connection. Make sure to modify the IP address, username, and password.

Monitoring your website on a shared host is vital to the well being of your existence on the internet. There are several online services that will do this for you in exchange for a small price. While they may be a bit more accurate, I would like to share with you how to use RRDTool to monitor your website’s response time yourself.

NOTE: I am using Ubuntu based Linux Mint. This process should be the same on other Debian based distributions. If you are not running a Debian based distribution, you may have to modify some paths to the rrdtool executable. Some of this procedure has been taken from the rrdwiki.

The first step is to install RRDTool:

sudo apt-get install rrdtool

Lets face it, no one likes performing manual backups. Often if monotonous tasks are not automated in some way (which they should be, that is why computers were invented) they will be forgotten and not performed regularly.

By using Linux wget and cron, we can incrementally backup websites and write a log file for each day. This will save time and network traffic.

This post features the same method I use to backup Hackosis on a daily basis.

Next, cd ~ into your home directory, or the location were you will be putting the website backup. create a new text file — touch websitebackup.sh. If you are backing up multiple websites, you may wish to name the file specific to the website you are backing up to avoid confusion.

Now execute chmod u+x websitebackup.sh to give the file execute permissions.

Have you ever noticed linking to your email in a mailto tag on a website generates instant spam to your inbox? Spambots are constantly scavenging the Internet for email addresses.

By using a simple Javascript method, email addresses can be hidden from spambots on web pages. When scripting is disabled, the noscript tag can be used to link to a modified email that spambots will not be able to use.

Example using myemail@domain.com:
