Oct 16, 2013 By Web Traffic Exchange Linux 0 Last Modified on 2024-01-16

Apache is the most popular web server being used today. Apache Killer exploit which was released in August 2011, exploits a vulnerability in the Apache software by sending a crafted "Range" HTTP header. Apache Killer attack abuses the HTTP protocol by requesting URL content to be returned in a huge number of small chunks, which leads to hundreds of large memory fetches causing a server to run out of memory and crash. This vulnerability identified as CVE-2011-3192 was fixed in httpd-2.2.21.

Using Doctrine as an ORM to persist your data significantly lowers your overhead in managing your database. However, if you're just getting started with Doctrine, you'll have to invest in moderate time to overcome the learning curve.

CSS Specificity - Which CSS Rule to apply?

Feb 16, 2015 By Web Traffic Exchange Development 0 Last Modified on 2024-01-16

Each CSS selector has a specificity value and the more specific the selector is the higher precedence it has. If multiple selectors apply to a single element, the highest specificity CSS rule applies to the element. Have you had an experience where you define a CSS rule for an element, and it doesn't work? You probably have a CSS rule that has a higher specificity value which causes your newly created CSS rule to not apply.

Getting started with composer (composer.phar)

I am kicking off a new PHP project with the Zend Framework 2 (ZF2) and chose to use Doctrine as the persistence layer with ORM capabilities. Knowing that I need two Zend modules for Doctrine support, I've cloned the two modules (DoctrineModule and DoctrineORMModule) from GitHub to enable doctrine support in my ZF2 project. Oops, just installing those two Zend modules from GitHub do not make doctrine work! What am I doing wrong? Do I need a core Doctrine library from doctrine-project.org installed in addition to those two modules in order to make this work in ZF2? After a careful review of documentation, the preferred installation method was using "composer" not "git clone".

I have personally worked in the Netsuite platform for about a year and have worked with SuiteTalk and SuiteScript development tools to integrate a standalone e-commerce application into Netsuite. Although I do have administrative privileges, I have not thoroughly explored the available development tools that are offered by Netsuite.

jQuery anonymous and callback function declarations

Jun 16, 2015 By Web Traffic Exchange Development 0 Last Modified on 2024-01-16

JavaScript enables you to create anonymous functions to be executed immediately or when the document is ready, and also allows you to freely pass functions around to be executed at a later time. The default short-hand notation for jQuery wrapper is $, and unless your webpage has a conflict with other javascript libraries you may freely use $ to wrap any jQuery scripts. Since there are many variations of anonymous function calls, they are worth mentioning here.

How to change MySQL user and root password?

Apr 12, 2015 By Web Traffic Exchange Databases 0 Last Modified on 2024-01-16

We have been using the DirectAdmin control panel for a number of years, and each time we set up a server it is necessary to change the root password. By default, Direct Admin creates a MySql superuser called "da_admin" with a preassigned password, but we do not know what the root password is. Since we use both DirectAdmin and command-line to manage our server, it is essential that we have a proper MySQL root password assigned.
