Install , Configure, Fine tune APC (Alternative PHP Cache) to Cut down CPU load on Server

APC performance

PHP has established itself well enough to be one of the most Popular Web programming language. PHP needs to be optimized sometimes in order to get better optimization and speed enhancements.

While getting accessed, every page in PHP needs to First get parsed by Interpreter, followed by a conversion to an intermediary format called opcode. At last, it finally gets converted into machine code which is executed by the server’s CPU.

This process is acceptable for Some cycles. But If the same script is accessed 100 times these steps are repeated a 100 times. To avoid this repetition and waste of server resources you can use the Alternative PHP Cache or APC.

The Alternative PHP Cache (APC) is a free and open opcode cache for PHP. Its goal is to provide a free, open, and robust framework for caching and optimizing PHP intermediate code.

Image Processing Concepts and Fundamentals

As many of my friends wanted me to write something about Image processing, when and how it is done and basic fundamentals of Image Processing, here I am with you to explain the Concepts and Fundamentals  Image Processing.

Introduction

Modern digital technology has made it possible to manipulate multi-dimensional signals with systems that range from simple digital circuits to advanced parallel computers. The goal of this manipulation can be divided into three categories:

* Image Processing image in -> image out

* Image Analysis image in -> measurements out

* Image Understanding image in -> high-level description out [Read more...]
