Magento and Memcached: Faster Caching for Your Store

memcachedAs your customers browse through your Magento store, Magento will often write various information to disk in an effort to present a smoother, more pleasant experience to the end user. These objects are often various core systems, popular PHP calls and various other blocks of information that the Magento system gets requests for many times over from the customer. It’s much faster for Magento to store these requests in a caching system on the drive than have to rebuild the information with every single request.

However, drive access times are a major bottleneck in server resources. While retrieving from cache is certainly faster than processing the request from code, accessing the drive is slower than other storage mediums available to a web server… namely, RAM.

Securing E-Commerce Emails with DMARC

Securing E-Commerce Emails with DMARC

2014-07-28_09-14-11

What is DMARC?

As E-Commerce sites have gained popularity in recent years, malicious activity such as spamming and phishing has also been on the rise. DMARC addresses these issues by providing a way for E-Commerce site owners (and mail senders) to protect their end users by securing and verifying communication channels. DMARC stands for “Domain-based Message Authentication, Reporting, and Conformance.”

How does DMARC work?

DMARC works by using both SPF (Sender Policy Framework) records and DKIM (Domain Keys Identified Mail) to inform the receiving server what to do with a message that fails either authentication pass. This helps to prevent fraudulent or harmful spoofing of domain emails and ensures that emails passing the authentication requirements are legitimately send from the actual store or domain.

Installing Magento from the Command Line

 

There are several methods of installing Magento to a web server and getting your e-commerce presence up and running. Magento offers a downloader application and script to automate most of the installation. However these methods still require the user to navigate to the freshly-installed site and use the web-based Installation Wizard to complete the process. What if the software that runs your web server isn’t quite configured as you’d want it, but you want to get the store up and running for local testing anyway?

Screen Shot 2014-07-23 at 3.10.38 PMMagento offers a method of completing an installation fully from the command line, with no web interaction needed! This method requires only an SSH connection to your server and the standard prerequisites to a Magento installation: MySQL/Percona and PHP 5. The following tutorial will guide you through installing a Magento store with sample data, and assumes the server has MySQL 5.1+ and PHP 5.3+ already installed.
