The network is everywhere. At the office, machines are wired together into local area networks, and the local networks are interconnected via the Internet. At home, personal computers are intermittently connected to the Internet or, increasingly, via "always-on" cable and DSL modems. New wireless technologies, such as Bluetooth, promise to vastly expand the network realm, embracing everything from cell phones to kitchen appliances. Such an environment creates tremendous opportunities for innovation. Whole new classes of applications are now predicated on the availability of high-bandwidth, always-on connectivity. Interactive games allow players from around the globe to compete on virtual playing fields and the instant messaging protocols let them broadcast news of their triumphs to their friends. New peer-to-peer systems, such as Napster and Gnutella, allow people to directly exchange MP3 audio files and other types of digital content. The SETI@Home project takes advantage of idle

The idea of this bood is to provide a reference guide to everything you could possibly want to know about Perl. I've done my best to try and cover all the different aspects, from the core of the language to the different functions, and on into the different tasks and areas of the Perl language. I even cover how to debug your software, write documentation, and then build and distribute your applications or modules to the world at large. Along the way, we also look at some nonstandard features and extensions, including better ways of networking, web programming, and designing interfaces.

I use this book all the time, as I did the previous edition. It's the book I turn to for all my Perl questions. Full disclosure: I know the author, but I'm no Perl expert. I qualify as a beginner (esp. since every time I use Perl, it's six months since the last time, and I have to start over). I emailed him to ask about the Perl 5.10 on the cover and apparently that was something the publisher did without checking with him. He didn't know about it until the book was out and it was too late to do anything about it.

Modern Perl now handles Unicode and recognizes that the world is more than just ASCII. You need to get over that hump, too, so we’ve added an entire chapter on it. Perl might be one of the most-tested code bases, a trend started by Michael Schwern several years ago and now part of almost every module distribution. Gone are the days when Perlers celebrated the Wild West days of code slinging. Now you can have rapid prototyping and good testing at the same time. If you’re working in the enterprise arena, you’ll want to read our advice on testing. If you’re a regular-expression fiend, you’ll want to use all of the new regex features that the latest versions of Perl provide. We’ll introduce you to the popular ones.

To solve performance problems in modern computing infrastructures, often comprising thousands of servers running hundreds of applications, spanning multiple tiers, you need tools that go beyond mere reporting. You need tools that enable performance analysis of application workflow across the entire enterprise. That's what PDQ (Pretty Damn Quick) provides. PDQ is an open-source performance analyzer based on the paradigm of queues. Queues are ubiquitous in every computing environment as buffers, and since any application architecture can be represented as a circuit of queueing delays, PDQ is a natural fit for analyzing system performance. Building on the success of the first edition, this considerably expanded second edition now comprises four parts. Part I contains the foundational concepts, as well as a new first chapter that explains the central role of queues in successful performance analysis. Part II provides the basics of queueing theory in a highly intelligible style for the

Perl is something of a weekend warrior. Outside of business hours you’ll find it indulging in all kinds of extreme sports: writing haiku; driving GUIs; reviving Lisp, Prolog, Forth, Latin, and other dead languages; playing psychologist; shovelling MUDs; inflecting English; controlling neural nets; bringing you the weather; playing with Lego; even running quantum computations. But that’s not its day job. Nine-to-five it earns its keep far more prosaically: storing information in databases, extracting it from files, reorganizing rows and columns, converting to and from bizarre formats, summarizing documents, tracking data in real time, creating statistics, doing back-up and recovery, merging and splitting data streams, logging and checkpointing computations. In other words, munging data. It’s a dirty job, but someone has to do it. If that someone is you, you’re definitely holding the right book. In the following pages, Dave will show you dozens of useful ways to get those everyday data
