What do readers say about Ada & Zangemann?
Tech media and interested individuals have shared their reviews about Ada & Zangemann - A Tale of Software, Skateboards, and Raspberry Ice Cream.
"A rousing tale of self-reliance, community and standing up to bullies, no matter how powerful they may be."
Cory Doctorow - Sci-fi author
"Introduces readers young and old to the power and peril of software. It also highlights the accelerating effects of sharing software freely - creating conditions for direct and indirect collaboration which can be a metaphor for the conduct of science. Behind it all is a backdrop of ethics of knowledge sharing upon which the arc of human history rides."
Vint Cerf - Computer Scientist and one of the inventors of the internet
"I love this book and I love that it can be shared and translated and adapted easily because licensed freely under a Creative Commons license (BY-SA)."
Lawrence Lessig, Roy L. Furman Professor of Law and Leadership at Harvard Law School, Founder Creative Commmons
"I am really pleased with Ada & Zangemann. It is very important for the world to understand that ‘the right to tinker’ and ‘the right to repair’ are essential to the development of future generations. I started out tinkering with radio and electronics at an early age when all electronic equipment came with a schematic diagram. Recently, almost everything is built out of mostly opaque parts, running opaque software. I want future scientists and engineers to be able to build stuff and modify the software, with friends, in the way that I did.”
Gerald Jay Sussman, Panasonic Professor of Electrical Engineering, MIT
"A fun children's tale about a very adult issue.”
Bruce Schneier, security technologist, lecturer, and author
"Ada and Zangemann explains the concepts of FOSS to school kids… and managers, marketing people, and victims of Windows-induced Stockholm Syndrome. [...] The book explains this in accessible terms of ice cream flavors, smart skateboards, and speakers which are restricted in what music they play. [...] [I]t gives kids agency: it shows them that they can have control of something and do their own thing."
Liam Proven, The Register
"Ada & Zangemann proves that the argument for software and hardware freedom is simple: We should be able to do what we want with our stuff. . . . Electronics freedom means more learning and less waste, as Ada shows. Kids and adults alike will be entertained by this book, charmed by its illustrations, and inspired by Ada’s engineering spirit and impassioned activism."
Elizabeth Chamberlain, Director of Sustainability, iFixit
"Ada & Zangemann is not only a utopian and charming story about Free Software and computers, but it is one about self-empowerment and also about joy in technology. . . . it may well be an eye-opener for adults, too."
Dr. Constanze Kurz, Spokesperson, Chaos Computer Club (CCC)
“[T]he book [is] actually more than a fairy tale about software, skateboards and pyramid-shaped ice cream with coloured sprinkles. It is a motivation for the first demo and a little bit of civil disobedience. It is a utopia of possibilities to make the world better with limited means and little money, and an example without moralistic finger-pointing, that control does not make happy.”
Anna Biselli, Editor-in-Chief Netzpolitik.org
"This book illustrates the power of free and open source software in a way that's both fun and accessible."
Chris Wright, CTO and open source technologist
"It's a hit -- in the first week my kid has read this book 3 or 4 times already, and says this book explains my work on software freedom finally in a way that's easily understandable."
Karen Sandler, Executive Director, Software Freedom Conservancy
"This book is the story of a collective liberation initiated by a curious and inspiring little girl. It’s the story of a digital world that empowers rather than alienating. But this book also has a beautiful story. The authors of the original version have placed it under a free license. In this case, copyright is no longer “all rights reserved”, but allows the work to be used, modified and shared. This choice encourages the circulation of the work, which is how I discovered the existence of Ada & Zangemann. This choice also favors translations of the work, which gave me the idea of a collaborative educational project for its French translation. More than a hundred students, aged 13 to 19, translated the book from German into French, sharing the work and coordinating digitally. Well done to them! And thanks to their teachers and to ADEAF (Association for the development of German language teaching in France) for making this possible. At the Ministry, we support the development of digital commons as part of our digital education and digital literacy missions. The theme of this book and its young translators are a remarkable example."
Alexis Kauffmann, Project manager for free software and educational resources at the French Ministry of Education and Youth, and founder of Framasoft.
"At the end of the book, the eyes of my 6-year old child gleamed with joy at the idea of a liberated, now almighty ice cream machine. Such is the spark that Ada & Zangemann can ignite in children of all ages. We need young generations to share Ada's enthusiasm, in order to take back control of everyday technology."
Stefano Zacchiroli, Professor at the Polytechnic Institute of Paris, co-founder of Software Heritage, former Debian Project Leader
"Together with illustrator Sandra Brandstätter, the author has succeeded in creating a technoid fairy tale with a contemporary moral"
"Ada & Zangemann tells an exciting story that will delight children and adults alike. IT describes the problems of the current tech oligopolies and how people can overcome them if they stick together and dare. The text is ingeniously complemented by the illustrations, which almost pass for a hidden object book."
Christoph Hellwig, Developer kernel Linux
"Even as a non-child, I was captivated by the story from the first page to the last. Kudos to the author for packaging difficult topics such as monopolies, lobbyism, digital divide, software freedom, digital autonomy, IoT, consumer control, e-waste and much more in a child-friendly form in an easily understandable and exciting storyline."
Jörg Luther, chief editor of the German Linux-Magazin, LinuxUser, Raspberry Pi Geek.
"The IT fairy tale we need"
"I . . . appreciated how [Ada & Zangemann] took a traditional children's morality tale format and modernized it with practical hardware/software ethics in a relatable way, but not in a way that made you feel preached to or talked down to. Would recommend!"
Kyle Rankin, Author and President of Purism
"After my son was read the book last night, he told me the whole story this morning... He wants to make something out of old pallets after school today. And then he wants to learn programming."
Ingo Wichmann, CEO Linuxhotel GmbH
"Especially in this day and age, the question of how to deal with software and in particular how to use it is everywhere. Matthias Kirschner and Sandra Brandstaetter capture the spirit of our time and bring a highly topical, technically relevant subject to children."
Catharina Maracke, Chair of the Board, Open Source Initiative
"What a fun read! I recognize myself in Ada at many moments. All I know about computers is thanks to Free Software, the internet, and the willingness of others to share their knowledge as Ada did."
Isabela Fernandes, Executive Director, The Tor project
"It's a treat!"
Sarah Novotny, Open Source Wonk
"Explaining what we do is challenging at times, but this book does so gracefully. I'm sure this cute little story will help both kids and many parents about technological empowerment."

Gerald Pfeifer, CTO of SUSE
"I loved the book; I found the theme very important and interesting, and the message delighted me (first the resourcefulness of Ada, then the demonstration which unites the whole city, and finally the Parliament which learns from its mistakes). This book is exactly what I want to pass on to my children!"
Canelle A., 18-year-old student translator in a Parisian high school
"A delightful and imaginative exploration of a lot of deeper ideas. My 5-yr-old was drawn in, laughing at the silly parts and marveling at the computers, while I was reflecting on the messages about how easily we tolerate control and lack of freedom"
John Goerzen, programmer and Debian Developer
"This modern tale is a superb parable, and a perfect illustration of the need for digital freedoms in our daily lives. Here we're talking about skateboards and toys, but tomorrow our whole lives may be limited by monopolist technology companies.
I love the format of this book, as I'm a big fan of comics. But above all, the tone is positive, laughing, and optimistic for the future, so that new generations will be stronger than we have been."JB Kempf, President, VideoLAN
"Technology is for everyone...at least, that's the moral of Ada & Zangemann: A Tale of Software, Skateboards, and Raspberry Ice Cream by Matthias Kirchner and Sandra Brandstätter. This beautifully written and illustrated story follows a technological revolution that occurs when an inventor becomes enraged by the use of his creations for fun, rather than their intended purposes. Encouraging creative, out-of-the-box engineering thinking, problem-solving, and perseverance, as well as endless tinkering, Kirchner and Brandstätter weave a story that will encourage children to question who owns the technology around them, and why."
A.R. Miller, Purdue Reviewer
"I like how it makes a positive statement that girls can code and use computers."
Child Reviewer, Purdue
"If human intelligence and politics harmonised as they do in this book, our world would be a different one - and certainly a better one. Children to power!"
Elli Mayr, City Councillor for Education, Innsbruck
"I loved the fact that the children took action without the help of their parents, that the government asked the next generation for help to master its information system, and that the toys are being recycled to hack and improve them (circular economy). As a civil servant, it also reminds me of the responsibility that we have. And the drawings are really great!"
Laurent Joubert, Chief Operating Officer, eHealth agency
"A wonderfully entertaining read with an empowering message for younger generations, one which will shape our world and the way we live in it."
Kaye Fogarty, The English International College, Marbella
"This book is a great way to expose people to the concept of software freedom and the concept of privacy and surveillance. I believe it is a great way to advocate for those values in a way I haven’t quite seen before."
Henry Fisher, Techlore
"Ada and Zangemann is a wonderful book which frames the vision of software freedom in a colorful, exciting, and accessible way that should connect to readers of all ages without being overbearing. Ada is a wonderful girl and I hope her spirit of community and freedom is something that young readers will bring to their own lives."
Drew DeVault, CEO SourceHut, Developer of KnightOS, Sway, Aerc, and others
“A children’s book under a free licence, translated into French by a hundred students, presents a modern tale of skateboards, raspberry ice cream, free computing and tinkering. A highly recommended Christmas gift.”
Thierry Noisette, ZDNet.fr
