“When life gives you lemons, make lemonade.” In this imaginative take on that popular saying, a child is surprised (and disappointed) to receive a lemon tree from Grandma for her birthday. After all, she DID ask for a new gadget! But when she follows the narrator’s careful—and funny—instructions, she discovers that the tree might be exactly what she wanted after all. This clever story, complete with a recipe for lemonade, celebrates the pleasures of patience, hard work, nature, community . . . and putting down the electronic devices just for a while.

    With compassion, humor, insight, and practical wisdom born of firsthand experience, Galit Breen makes a compelling case for online decency. What would happen if parents and kids everywhere could read these 10 simple rules of conduct, learn them by heart, and live by them each and every time they log in? The world would change dramatically--and for the good of us all."--Katrina Kenison, author of Mitten Strings for God and The Gift of an Ordinary DayIf kindness wins, accountability rules. The need for this mantra is never clearer than when scrolling through posts and comments online.Approximately four out of ten kids (42 percent) have experienced cyberbullying. When we were young, our bullies weren't usually strangers. They were the kids who passed mean notes about us in class, the ones who didn't let us sit at their table during lunch, and the ones who tripped us in the hallway or embarrassed us in gym class. Cyberbullying isn't all that different from the playground bullying of our youth and nightmares. But with social media, our bullies have nonstop access to us--and our kids. In fact, we're often "friends" with our bullies online.When freelance writer Galit Breen's kids hinted that they'd like to post, tweet, and share photos on Instagram, Breen took a look at social media as a mom and as a teacher and quickly realized that there's a ridiculous amount of kindness terrain to teach and explain to kids―and some adults―before letting them loose online. So she took to her pen and wrote a how-to book for parents who are tackling this issue with their kids.Kindness Wins covers ten habits to directly teach kids as they're learning how to be kind online. Each section is written in Breen's trademark parent-to-parent-over-coffee style and concludes with resources for further reading, discussion starters, and bulleted takeaways. She ends the book with two contracts―one to share with peers and one to share with kids. Just like we needed to teach our children how to walk, swim, and throw a ball, we need to teach them how to maneuver kindly online. This book will help you do just that.

    Also lacking is public intelligence in the sense of decision-support: knowing what one needs to know in order to make honest decisions for the good of all, rather than corrupt decisions for the good of the few.The Open-Source Everything Manifesto is a distillation of author, strategist, analyst, and reformer Robert David Steele life's work: the transition from top-down secret command and control to a world of bottom-up, consensual, collective decision-making as a means to solve the major crises facing our world today. The book is intended to be a catalyst for citizen dialog and deliberation, and for inspiring the continued evolution of a nation in which all citizens realize our shared aspiration of direct democracy—informed participatory democracy. Open-Source Everything is a cultural and philosophical concept that is essential to creating a prosperous world at peace, a world that works for one hundred percent of humanity. The future of intelligence is not secret, not federal, and not expensive. It is about transparency, truth, and trust among our local to global collective. Only "open" is scalable. As we strive to recover from the closed world corruption and secrecy that has enabled massive fraud within governments, banks, corporations, and even non-profits and universities, this timely book is a manifesto for liberation—not just open technology, but open everything.

    Blade Runner, The Matrix, Star Wars, Avatar, Star Trek, Ready Player One and Avengers show us futuristic worlds where holograms, intelligent robots, smart devices, virtual avatars, digital transactions, and universe-scale teleportation work together perfectly, somehow seamlessly combining the virtual and the physical with the mechanical and the biological. Science fiction has done an excellent job describing a vision of the future where the digital and physical merge naturally into one — in a way that just works everywhere, for everyone. However, none of these visionary fictional works go so far as to describe exactly how this would actually be accomplished. While it has inspired many of us to ask the question—How do we enable science fantasy to become....science fact? The Spatial Web achieves this by first describing how exponentially powerful computing technologies are creating a great “Convergence.” How Augmented and Virtual Reality will enable us to overlay our information and imaginations onto the world. How Artificial Intelligence will infuse the environments and objects around us with adaptive intelligence. How the Internet of Things and Robotics will enable our vehicles, appliances, clothing, furniture, and homes to become connected and embodied with the power to see, feel, hear, smell, touch and move things in the world, and how Blockchain and Cryptocurrencies will secure our data and enable real-time transactions between the human, machine and virtual economies of the future. The book then dives deeply into the challenges and shortcomings of the World Wide Web, the rise of fake news and surveillance capitalism in Web 2.0 and the risk of algorithmic terrorism and biological hacking and “fake-reality” in Web 3.0. It raises concerns about the threat that emerging technologies pose in the hands of rogue actors whether human, algorithmic, corporate or state-sponsored and calls for common sense governance and global cooperation. It calls for business leaders, organizations and governments to not only support interoperable standards for software code, but critically, for ethical, and social codes as well. Authors Gabriel René and Dan Mapes describe in vivid detail how a new “spatial” protocol is required in order to connect the various exponential technologies of the 21st century into an integrated network capable of tracking and managing the real-time activities of our cities, monitoring and adjusting the supply chains that feed them, optimizing our farms and natural resources, automating our manufacturing and distribution, transforming marketing and commerce, accelerating our global economies, running advanced planet-scale simulations and predictions, and even bridging the gap between our interior individual reality and our exterior collective one. Enabling the ability for humans, machines and AI to communicate, collaborate and coordinate activities in the world at a global scale and how the thoughtful application of these technologies could lead to an unprecedented opportunity to create a truly global “networked” civilization or "Smart World.” The book artfully shifts between cyberpunk futurism, cautionary tale-telling, and life-affirming call-to-arms. It challenges us to consider the importance of today’s technological choices as individuals, organizations, and as a species, as we face the historic opportunity we have to transform the web, the world, and our very definition of reality.
