I have a passion for knowledge and I realise that part of the responsibility of gathering knowledge is being able to advance the state of the human condition in some way.

My aims in writing these books are to play with software, achieve personal goals and try something new for fun. It also helps that I think Open Source, technology, the visual representation of data and information rock in serious ways.

The books that I write are a mechanism to support my own learning, so the way I explain things is focused on trying to impart understanding in a simple but functional way.

I'm totally in awe of the Open Source community that has made this type of work possible. If you feel that you would like to support continued development of this content, feel free to donate when you download.

If you're looking for a hard copy version of any of these publications, they will be available through Amazon (not all will be available sorry).

J. B. Rainsberger helps software companies better satsify their customers and the businesses they support. Over the years, he has learned to write valuable software, overcome many of his social deficiencies, and built a life that he loves. He travels the world sharing what he's learned, hoping to help other people get what they want out of work and out of their lives. Even though he's traveled Europe most of the past two years, he lives in Atlantic Canada with his wife, Sarah, and two cats.

I've always been interested in helping smart people be happy and productive. To that end, I've published books on human behavior, including Weinberg on Writing: The Fieldstone Method, The Psychology of Computer Programming, Perfect Software and Other Fallacies, and an Introduction to General Systems Thinking. I've also written books on leadership including Becoming a Technical Leader, The Secrets of Consulting (Foreword by Virginia Satir), More Secrets of Consulting, and the nine-volume Quality Software series.

I try to incorporate my knowledge of science, engineering, and human behavior into all of my writing and consulting work (with writers, hi-tech researchers, software engineers, and people whose life-situation could require the use of a service dog). I write novels about such people, including The Aremac Project, Aremac Power, Jigglers, First Stringers, Second Stringers, The Hands of God, Freshman Murders, Where There's a Will There's a Murder, Earth's Endless Effort, and Mistress of Molecules—all about how my brilliant protagonists produce quality work and learn to be happy. My books that are not yet on Leanpub may be found as eBooks at <http://www.smashwords.com/profile/view/JerryWeinberg>; on Amazon at http://www.amazon.com/-/e/B000AP8TZ8; and at Barnes and Noble bookstore: http://tinyurl.com/4eudqk5.

Early in my career, I was the architect for the Project Mercury's space tracking network and designer of the world's first multiprogrammed operating system. I won the Warnier Prize, the Stevens Award, and the first Software Testing Professionals' Luminary Award, all for my writing on software quality. I was also elected a charter member of the Computing Hall of Fame in San Diego and chosen for the University of Nebraska Hall of Fame.

But the "award" I'm most proud of is the book, The Gift of Time (Fiona Charles, ed.) written by my student and readers for my 75th birthday. Their stories make me feel that I've been at least partially successful at helping smart people be happy.

Julien Bayle is a multidisciplinary and independent artist based in France and working at the juncture of sound & visual. He merges visual art, music composition, physical approach of sound art and data visualization by creating advanced programmed installations and audio/visual live performances.He tries to address the question of disrupted continuum, interferences and representation of concepts by using physics of sound and error/artifact magnification.

His work is based on both experimentations and programming, using concepts of time expansion & contraction as main guidelines. His interests for all microsound and granular synthesis expand his work and open a new way of including field recording and previously designed sound into his own practices. He seeks to depict a world saturated by meaningless informations , societies complexity through a positive-nihilist kind of deconstruction of processes, structures and results.

He performed his audio-visual live performances in international festivals like ELEKTRA in Canada, or sound:frame in Austria and exhibited his work in galleries in Europe. He’s also a art teacher and he provides advanced technical courses about the place of technology in new media creation, invited by different art schools in Europe.

He's an Ableton Certified Trainer and Max MSP programmer expert. He also speaks and read C++ & OpenFrameworks, Java & Processing, Arduino & Physical Computing.

He co-leads the Bordille Records art label with François Larini, works closely with & records for Canadian imprint Yatra Arts and was selected artist of SHAPE Network during 2016.

Writer.  

But also scholar, lecturer, former computer programmer, with a background in science, a passion for history and literary biography, and an interest in the relationship between belief and perception.  This sentence should explain my (perhaps disparate-seeming) writing interests:  fiction and poetry (including The Marlowe Papers and Devotion), scholarly articles and books on Shakespeare and Marlowe (including Shakespeare the Evidence), and self-development work (including How to Achieve the Impossible).  Having tried to separate myself into these different pockets for a few years (aware that to many they seem incompatible) I am now stitching myself together.

I love fiction.  But I also love fact.  There is a lot of fiction being passed off as fact, and vice versa. I do what I can to redress the balance.

I like clarity. I aim to achieve more of it. I try to help others have more of it too.

There. Suddenly everything I do makes sense.
