This book covers bash, the GNU Bourne Again Shell, which is a member of the Bourne family of shells that includes the original Bourne shell sh, the Korn shell ksh, and the Public Domain Korn Shell pdksh. While these and other shells such as dash, and zsh are not specifically covered, odds are that most of the scripts will work pretty well with them.
You should be able to read this book cover to cover, and also just pick it up and read anything that catches your eye. But perhaps most importantly, we hope that when you have a question about how to do something or you need a hint, you will be able to easily find the right answer—or something close enough—and save time and effort.
A great part of the Unix philosophy is to build simple tools that do one thing well, then combine them as needed. This combination of tools is often accomplished via a shell script because these commands, called pipelines, can be long or difficult to remember and type. Where appropriate, we’ll cover the use of many of these tools in the context of the shell script as the glue that holds the pieces together to achieve the goal.

Chapter 1 explains what CodeIgniter can do, the 'framework', and how CodeIgniter fits in. It further talks about the open-source business model and gives some disadvantages of CodeIgniter, at the end.
Chapter 2 explains what happens when you install the site, and which files will be created. It gives a detailed overview of the required software, and explains the basic configuration of CodeIgniter.
Chapter 3 explains how MVC helps to organize a dynamic website. It goes further to explain the process by which CodeIgniter analyzes an incoming Internet request and decodes which part of your code will handle it. Then CodeIgniter syntax rules and the different types of files or classes you can find—or write for yourself—on a CodeIgniter site are explained. At the end of the chapter, some practical hints on site design are given.
Chapter 4 looks at how you set up a database to work with CodeIgniter, and then how you use the Active Record class to manipulate the database.

I ’ m especially amazed at how the Internet has grown and evolved over the past decade or so. It has grown from a collection of static text documents connected by a few hyperlinks to a platform for delivering rich, distributed applications. And when it comes time to develop these web - based applications, many programmers are choosing PHP and MySQL.

In this book, I present basic code for 12 PHP - powered projects that you can use and extend however you wish. I have tried to write them so the code can be easily reused in future applications, but in some instances the entire application can be reused as well!

I ’ ve enjoyed the opportunity to write and share with you this information and I hope you have just as much fun reading it and learning from it. More importantly, I hope you find good, practical uses for the projects found within this book.

Photography is a complex craft. Some excel at the technical side of image-making, focusing perfectly on the subject, releasing the shutter at just the right moment and making exposures with the precise amount of light. Others are artists and storytellers, capturing a fleeting moment in time which inspires a viewer to gaze upon an image and ponder its meaning. The best photographers are masters of both.

In this highly visual, informative new book, Angela Faris Belt discusses the four crucial elements of photography that are essential for successful technical and conceptual image-making:

the photographic frame and its borders
quality of focus as determined by the aperture or lens
shutter speeds and their effects in relation to time and motion
the physical media used to create the aggregate image

Step-by-step guidance including informative screen shots, traditional darkroom and Photoshop techniques, suggested exercises, and before and after images help both film and digital photographers improve their skills, learn new techniques, and better understand their craft. More than 300 stunning, full color images and portfolios featuring the work of over 40 prestigious artists provide visual inspiration as well as a gorgeous collection of artwork for photography enthusiasts.
