This document discusses web development and Facebook's technology stack. It begins with an introduction to open source software and web development basics. It then covers PHP and how Facebook uses open source technologies like Linux, Apache, MySQL, and PHP (LAMP stack) across its infrastructure. Specifically, it discusses how Facebook uses PHP HipHop, a source code transformer that compiles PHP into highly optimized C++ code, to improve performance of its sites and applications.

Web Development
Introduction to web development  What is web development ?  Web application Vs website  Web development advantages and disadvantages  What are technologies needed to be a developer  How To Start ?
What is web development? ●Web development is a broad term for the work involved in developing a web site or web application for the Internet or for private network. ●Web development can range from developing the simplest static single page of plain text to the most complex web- based Internet applications
Web application VS Website  Web application  Web site  An application  Collection of web uses web pages. technologies  Contains images ,  All processing are videos, and made in the other digital server side assets.  Accessed form  Must be hosted on web browser the Internet.  Can't contain  It may be static or static web dynamic. pages  Must use
Web development advantages  No special configuration or changes are need on user's PCs.  Lower costs.  Centralized data is secure and easy to backup.  Updates can be made quickly and easily.  Information is accessible to a wide audience anywhere in the world.  Available 24 hours a day, 7 days a week.  Always up-to-date.
Web development disadvantages  Slower, as it runs over the Internet  Can take longer to develop  As they are more complex.  As the site or application have to work on different browsers, and different versions of browsers.  Security risks
Needed technologies to be a developer
How TO Start / Where To Go  Start with studying technologies in this sequence 1. Apache web server basics 2. HTML / CSS 3. JavaScript 4. MySQL DBMS 5. PHP web programing language  Go To one of the following 1. Self study. (It takes long time) 2. Pi-Technologies (It takes 20 days + basic work experience)
Web Programming

What is web programming? Web server Send request Application / Website Web Programming • Code • Database • files • precompiled programs
Types of web programming  Server side programming  PHP  Perl  CGI  Python  ASP.NET  Client side programming  JavaScript  Action script
Web servers  A web server is a computer program that delivers content to the end user .  The term web server can also refer to the computer or virtual machine running the program.  commonly a web browser makes a request for a specific resource using HTTP.  While the primary function is to serve content, a full implementation of HTTP also includes a way of receiving content from clients.
