    One slogan of Perl is that it makes easy things easy and hard things possible. "Intermediate Perl" is about making the leap from the easy things to the hard ones.Originally released in 2003 as "Learning Perl Objects, References, and Modules" and revised and updated for Perl 5.8, this book offers a gentle but thorough introduction to intermediate programming in Perl. Written by the authors of the best-selling "Learning Perl," it picks up where that book left off. Topics include: Packages and namespacesReferences and scopingManipulating complex data structuresObject-oriented programmingWriting and using modulesTesting Perl codeContributing to CPANFollowing the successful format of "Learning Perl," we designed each chapter in the book to be small enough to be read in just an hour or two, ending with a series of exercises to help you practice what you've learned. To use the book, you just need to be familiar with the material in "Learning Perl" and have ambition to go further.Perl is a different language to different people. It is a quick scripting tool for some, and a fully-featured object-oriented language for others. It is used for everything from performing quick global replacements on text files, to crunching huge, complex sets of scientific data that take weeks to process. Perl is what you make of it. But regardless of what you use Perl for, this book helps you do it more effectively, efficiently, and elegantly."Intermediate Perl" is about learning to use Perl as a programming language, and not just a scripting language. This is the book that turns the Perl dabbler into the Perl programmer.

    Many of today’s jobs require that you be familiar with Microsoft Excel. How can you become proficient at Excel when companies aren’t willing to teach you this valuable skill? This leaves many people trying to learn as they go and never quite feeling 100% comfortable with the program. What’s worse, most people haven’t even scratched the surface of Excel’s potential, even if they’ve been using it for years. If you feel this way, you’re not alone. Think about this for a second; what will your career look like in a year if you don’t take action today and improve your Excel skills? How about five years from now? Unless you take matters into your own hands things may not look much different. According to a recent Wall Street Journal article, people who show proficiency in Microsoft Excel and other common office applications earn, on average, 13% more than those who don’t. For most people this could mean tens of thousands of dollars over just a few years, and this doesn’t even factor in lost promotions and job offers. Can you afford to leave so much on the table as a result of maintaining the status quo? I’ve experienced this transformation in my career and can tell you first hand how it has helped me. When I was fresh out of college and working my first accounting job my manager asked me to complete a project that involved using VLOOKUPS. I enthusiastically obliged, walked back to my desk, and proceeded to panic. I tricked myself into thinking that I was an excel expert only because I knew a few formulas, my limited knowledge only scratched the surface. I turned to a college buddy for help; Google. I eventually managed to learn what I needed, after a lot of time and energy. I’ve climbed the ladder and worn many hats since then. I can’t say that the opportunities I’ve earned in my career are solely due to my increasing Excel proficiency. What I can definitely say is that Excel has earned me more opportunities to prove myself to management than waiting for opportunities to materialize on their own. That’s why I decided to write this book. My goal is to take you from Excel novice to master in the shortest time possible. I wrote my book specifically for the busy professional, in an easy to read manner that gets straight to the point and teaches the meat of Excel. I wrote this book for you. Don’t take my word for it: "I think the writing style is helpful for readers to engage. I like that as I read the book, I felt as if I was in front of someone who was actually teaching me. I also liked the fact that the book is written in a laid back manner. I mean Excel is difficult as it is, why would you want to make it worst by adding some weird terminology to the book? Its plain, simple and easy to follow." -Eliana Pereira, Accountant I have helped many people improve their careers through Excel and now it’s your turn. Here is what you get when you download my book: -18 chapters of the most useful Excel techniques that will immediately take your skills to the next level -Practical use cases plus downloadable workbooks so that you can take what you learn and feel, first hand, how to apply those skills to real world scenarios -A FREE copy of my latest book on Google Sheets so you can stay ahead of the curve You’re at the point of decision.
