About the Authors

Juan Pablo Giménez's programming career started in 1996. He was a C/C++ programmer in real-time systems under the QNX OS, but quickly the philosophy of Linux and free software became more and more interesting for him as he became a sysadmin and a PHP programmer. In 2000 he began his own company, Rcom, through which he has provided IT services using FOSS tools to cover a wide range of languages and technologies. Despite having gone through abundant experience with other languages and CMS frameworks, today he focuses totally on developing products and sites under Plone.

I want to thank my family, my parents, my sister, and especially my grandmother Chola, for years of support and understanding while I sojourned in the-for them-incomprehensible world of programming.

Thanks to my best friends and associates in Rcom, Juan Pablo Noriega, Roman Mottino, Eugenio Oliveri, and Leandro Viani.

Thanks to Emanuel Sartor and the Plone community for always being there to help me in my learning process.

And thanks, Laura, for putting up with me and my crazy passions; without you, it would not have been possible for me to reach this far; thank you also for bringing to life Julieta and Sofia, the joy of my days.

Marcos F. Romero has been a software developer since 1997, working with Lotus Notes, both to develop applications, and as a trainer of users and other developers.

In 1999, he launched his first web site, after which he specialized in HTML, CSS, JavaScript, and DOM among other technologies.

Since then he has taken part in numerous other web sites and webapps—including a Lotus Notes CMS—and started working as a consultant to other professionals.

In 2007, he started to participate in Plone projects and became fascinated by the Open Source world.

For over 10 years he has been interested in Usability as a discipline applicable to everyday activities and, focused on the customer's and end user's needs, he aims to simplify and help their everyday tasks. Today he actively applies this concept in Inter-Cultura, a company that specializes in Usability and User Experience, where he has been working for several years.

All my appreciation to Gonzalo J. Auza, who ushered me into the world of Plone and who has supported me all along. A big thanks to Juan Pablo Giménez, who can't but continue to teach me; and to Martin Aspeli, Alec Mitchell, and Emanuel Sartor, who kindly agreed to share their knowledge by reviewing this book.

My gratitude to Rebeca Resnik, my English teacher, who has a lot to do with this endeavour.

A special thanks to my family and friends—especially to my parents—who phoned me continually for updates on my progress towards completion of this book.

But most of all, thanks to my wife, who lovingly did more than her share with our kids, buying me the time and quiet to complete this book.
