As a web programming language, one of PHP’s strengths traditionally has been to make it easy to write scripts that access databases so that you can create dynamic web pages that incorporate database content. This is important when you want to provide visitors with information that is always up-to-date, without hand tweaking a lot of static HTML pages. However, although PHP is easy to use, it includes no general-purpose database access interface. Instead it has a number of specialized ones that take the form of separate sets of functions for each database system. There is one set for MySQL, another for InterBase, and another for PostgreSQL—and others as well.

Although Python is a high-level language, it is not English or some other natural human language. The Python translator does not understand “add the numbers two and three”. Python is a formal language with its own specific rules and formats, which these tutorials will introduce gradually, at a pace intended for a beginner. These tutorials are also appropriate for beginners because they gradually introduce fundamental logical programming skills. Learning these skills will allow you to much more easily program in other languages besides Python. Some of the skills you will learn are

Welcome to the Python for XBMC Tutorial! This project began one day when I discovered XBMC (XBox Media Center) supports scripts written in Python. Darkie made the port, and I’d like to thank him for his great work and support! (I harassed him with questions and feature suggestions and he was always nice enough to reply to the questions and to add the features.) Curious, I decided to try to use this scripting language to display some basic stuff.

Although traditional firewalls have effectively prevented network-level attacks, most future attacks will be at the application level, where current security mechanisms are woefully inadequate. Application-level security vulnerabilities are inherent in a Web application’s code, regardless of the technology in which the application is implemented or the security of the Web server and backend database on which it is built. A recent advisory published by Internet Security Systems (see the “Internet Resources” sidebar, p. 44) claims that 11 widely deployed shopping cart applications are vulnerable to a simple attack that lets hackers pur- chase goods for much less than their listed price. Worryingly, the attack does not require particular technical skill; it suffices to save the shopping cart’s HTML confirmation form to disk, use a text editor to modify the price of the goods (stored in a hidden form field), and load the HTML form back into the browser.

Mashups
It’s been called the essence of Web 2.0. It’s the ability to combine pieces of different web sites to create something new, something meaningful. Something for you and the people who have your tastes. Your social network. Not some mass market portal built by corporate programmers who think that they know you and your personal tastes.

One of the common requirements in a Linux-based network is to include Linux workstations. There are a multitude of ways to do so; if this network also includes Windows workstations that are connecting to the Linux file server, you’re likely already using Samba. This document describes how to have a Linux workstation access data on a Linux file server via Samba. Here’s a quick tutorial to the essential steps involved in setting up a Linux File Server and having Linux workstations connect to it, using Fedora Core as an example.

The .NET Framework’s managed environment allows developers to improve their programming model to support a wide range of functionality. The goal of the .NET Framework design guidelines is to encourage consistency and predictability in public APIs while enabling Web and cross- language integration. It is strongly recommended that you follow these design guidelines when developing classes and components that extend the .NET Framework. Inconsistent design adversely affects developer productivity. Development tools and add-ins can turn some of these guidelines into de facto prescriptive rules, and reduce the value of nonconforming components. Nonconforming components will function, but not to their full potential.
