Review of the hardback: '… a fundamental new way of looking at constraint programming … This book … is a great present to the constraint programming community, which will certainly advance scientifically because of its publication. We need good books to educate new people to Constraint Programming in the best way, and this book is a great way to do this.' Theory and Practice of Logic Programming
Review of the hardback: '… a fundamental new way of looking at constraint programming … done with the highest level of precision and formality, without however making the reading task too heavy, as it is typical of Apt's writing style … I really enjoyed reading Apt's book and am using it for my current course on constraint programming … it is extremely well written … the formal style never makes reading a heavy task … it provides a very original abstract view of the main concepts of constraint propagation and constraint programming, which can be very useful both for beginners who need to understand[ing] these concepts without getting lost, and also for experienced researchers … I have always been stunned by his exceptional ability to be formal and clear. This book is yet another witness for this ability … a great present to the constraint programming community, which will certainly advance scientifically because of its publication. Journal of TLP
Is there any sexier topic in software development than software testing? That is, besides game programming, 3D graphics, audio, high-performance clustering, cool websites, et cetera? Okay, so software testing is low on the list. And that's unfortunate, because good software testing can increase your productivity, improve your designs, raise your quality, ease your maintenance burdens, and help to satisfy your customers, coworkers, and managers.
Perl has a strong history of automated tests. A very early release of Perl 1.0 included a comprehensive test suite, and it's only improved from there. Learning how Perl's test tools work and how to put them together to solve all sorts of previously intractable problems can make you a better programmer in general. Besides, it's easy to use the Perl tools described to handle all sorts of testing problems that you may encounter, even in other languages.
Like all titles in O'Reilly's Developer's Notebook series, this "all lab, no lecture" book skips the boring prose and focuses instead on a series of exercises that speak to you instead of at you.
Perl Testing: A Developer's Notebook will help you dive right in and:
* Write basic Perl tests with ease and interpret the results* Apply special techniques and modules to improve your tests* Bundle test suites along with projects* Test databases and their data* Test websites and web projects* Use the "Test Anything Protocol" which tests projects written in languages other than Perl
With today's increased workloads and short development cycles, unit tests are more vital to building robust, high-quality software than ever before. Once mastered, these lessons will help you ensure low-level code correctness, reduce software development cycle time, and ease maintenance burdens.
You don't have to be a die-hard free and open source software developer who lives, breathes, and dreams Perl to use this book. You just have to want to do your job a little bit better.
With a worldwide community of users and more than a million dedicated programmers, Perl has proven to be the most effective language for the latest trends in computing and business.
Every programmer must keep up with the latest tools and techniques. This updated version of Advanced Perl Programming from O'Reilly gives you the essential knowledge of the modern Perl programmer. Whatever your current level of Perl expertise, this book will help you push your skills to the next level and become a more accomplished programmer.
O'Reilly's most high-level Perl tutorial to date, Advanced Perl Programming, Second Edition teaches you all the complex techniques for production-ready Perl programs. This completely updated guide clearly explains concepts such as introspection, overriding built-ins, extending Perl's object-oriented model, and testing your code for greater stability.
Other topics include:
* Complex data structures* Parsing* Templating toolkits* Working with natural language data* Unicode* Interaction with C and other languages
In addition, this guide demystifies once complex topics like object-relational mapping and event-based development-arming you with everything you need to completely upgrade your skills.
Praise for the Second Edition:
"Sometimes the biggest hurdle to problem solving isn't the subject itself but rather the sheer number of modules Perl provides. Advanced Perl Programming walks you through Perl's TMTOWTDI ("There's More Than One Way To Do It") forest, explaining and comparing the best modules for each task so you can intelligently apply them in a variety of situations." --Rocco Caputo, lead developer of POE
"It has been said that sufficiently advanced Perl code is indistinguishable from magic. This book of spells goes a long way to unlocking those secrets. It has the power to transform the most humble programmer into a Perl wizard." --Andy Wardley
"The information here isn't theoretical. It presents tools and techniques for solving real problems cleanly and elegantly." --Curtis 'Ovid' Poe
" Advanced Perl Programming collects hard-earned knowledge from some of the best programmers in the Perl community, and explains it in a way that even novices can apply immediately." --chromatic, Editor of Perl.com
Many programmers code by instinct, relying on convenient habits or a "style" they picked up early on. They aren't conscious of all the choices they make, like how they format their source, the names they use for variables, or the kinds of loops they use. They're focused entirely on problems they're solving, solutions they're creating, and algorithms they're implementing. So they write code in the way that seems natural, that happens intuitively, and that feels good. But if you're serious about your profession, intuition isn't enough. Perl Best Practices author Damian Conway explains that rules, conventions, standards, and practices not only help programmers communicate and coordinate with one another, they also provide a reliable framework for thinking about problems, and a common language for expressing solutions. This is especially critical in Perl, because the language is designed to offer many ways to accomplish the same task, and consequently it supports many incompatible dialects. With a good dose of Aussie humor, Dr. Conway (familiar to many in the Perl community) offers 256 guidelines on the art of coding to help you write better Perl code--in fact, the best Perl code you possibly can. The guidelines cover code layout, naming conventions, choice of data and control structures, program decomposition, interface design and implementation, modularity, object orientation, error handling, testing, and debugging. They're designed to work together to produce code that is clear, robust, efficient, maintainable, and concise, but Dr. Conway doesn't pretend that this is the one true universal and unequivocal set of best practices. Instead, Perl Best Practices offers coherent and widely applicable suggestions based on real-world experience of how code is actually written, rather than on someone's ivory-tower theories on how software ought to be created. Most of all, Perl Best Practices offers guidelines that actually work, and that many developers around the world are already using. Much like Perl itself, these guidelines are about helping you to get your job done, without getting in the way.
It all started with a series of odd statistics. The leading challenger to Microsoft's stranglehold on the computer industry is an operating system called Linux, the product of thousands of volunteer programmers who collaborate over the Internet. The software behind a majority of all the world's web sites doesn't come from a big company either, but from a loosely coordinated group of volunteer programmers called the Apache Group. The Internet itself, and much of its core software, was developed through a process of networked collaboration. The key to these stunning successes is a movement that has come to be called open source, because it depends on the ability of programmers to freely share their program source code so that others can improve it. In 1997, Eric S. Raymond outlined the core principles of this movement in a manifesto called The Cathedral & the Bazaar, which was published and freely redistributed over the Internet. This revolutionary book starts out with "A Brief History of Hackerdom"--the historical roots of the open source movement--and details the events that led to the recognition of the power of open source. It contains the full text of "The Cathedral & the Bazaar," updated and expanded for this book, plus Mr. Raymond's other key essays on the social and economic dynamics of open source software development. Open source is the competitive advantage in the Internet Age. The Cathedral & the Bazaar is a must for anyone who cares about the computer industry or the dynamics of the information economy. Already, billions of dollars have been made and lost based on the ideas in this book. Its conclusions will be studied, debated, and implemented for years to come.
