Perl For Dummies


Book Description

In the days before personal computers, BASIC was the easy programming language to learn, and serious programmers learned FORTRAN or COBOL to do “real work.” Today, many people have discovered that Perl is both a great beginning programming language and one that enables them to write powerful programs with little effort. If you’re interested in discovering how to program (or how others program), Perl For Dummies, 4th Edition, is for you. If you already know something about programming (but not about Perl), this book is also for you. If you’re already an expert programmer, you’re still welcome to read this book; you can just skip the basic stuff (you never know what kind of new tips and tricks you’ll pick up). This reference guide shows you how to use Perl under many different operating systems, such as UNIX, many flavors of Windows (Windows 95/98, Windows NT, Windows 2000, Windows Me, and Windows XP), and Macintosh OS 9 and OS X; in fact, Perl runs on many more operating systems than these. Here's a sampling of what Perl For Dummies, 4th Edition, has to offer: Installing Perl on various platforms Nailing down the basics of building Perl programs Working with text and numbers Constructing lists and working with them Creating conditionals and loops Delving into more advanced features such as operators and functions Reading and writing files and directories Using subroutines for modularity Demystifying Web server programs Creating your own Internet clients The Perl programming language enables you to write fully working computer programs with just a few steps. It’s particularly good at common programming tasks, such as reading and writing text files, but it also excels at reducing the work that programmers have to do. Perl For Dummies, 4th Edition, shows you how to do all of that and how to modify programs to your heart’s content. After all, one of the common phrases in the world of Perl programmers is, “There's more than one way to do it.”




Elements of Programming with Perl


Book Description

Many neophyte programmers now begin their careers by learning the metalanguage, Perl. But the books currently available on Perl assume their readers already understand the basics of writing and designing programs--when in fact they do not. The tutorial teaches programming right along with the particulars of Perl syntax, as well as good style and structure and maintainability of the code.




Perl Programming for the Absolute Beginner


Book Description

Arduino in easy steps


Book Description

Arduino in easy steps is for anyone wanting to get started with Arduino - the popular circuit board that allows users to build a variety of circuits. For artists, designers, hobbyists and anyone interested in creating interactive objects or environments. Arduino is the first widespread Open Source Hardware platform. It was launched in 2005 to simplify the process of electronic prototyping and it enables everyday people with little or no technical background to build interactive products. The Arduino ecosystem is a combination of three different elements: A small electronic board manufactured in Italy that makes it easy and affordable to learn to program a microcontroller, a type of tiny computer found inside millions of everyday objects.A free software application used to program the board.An online community, connecting thousands of people with others to contribute and ask for help with projects. Arduino in easy steps begins with an explanation of what Arduino is, why it came into being and what can be done with it. We see what is required both in terms of hardware and software, plus the writing of code that makes it actually work. The Arduino environment has to be installed and set up on the user’s computer and Arduino in easy steps provides full instructions for doing this with all the operating systems – Windows, Mac OS X, and Linux. The book explains what tools are required to build Arduino projects and also runs through certain techniques, such as soldering, that will be needed. Arduino in easy steps then provides a primer in basic electricity and electronics, which will help the reader to understand how electronic circuits work and how to build them. This is followed by another primer, this time on how to write the code that will enable users to program their projects, plus how to debug that code. To illustrate how to use Arduino, there is a chapter detailing a number of typical projects. For each of these projects, the required components, the schematic diagram, and the code are provided. The book also takes a look at how to extend the basic Arduino board with the use of shields. These enable the user to construct larger and more complex projects. Finally, Arduino in easy steps details where the reader can get further information and help on Arduino, advice on how and where to buy Arduino and other required electronic parts, and where to find ready-made code that can be freely downloaded.
