Like many others, I feel like I have learned more in the last couple of years studying Bitcoin than I have during two decades of formal education. The following lessons are a distillation of what I’ve learned. First published as an article series titled “What I’ve Learned From Bitcoin,” what follows can be seen as a third edition of the original series. Like Bitcoin, these lessons aren’t a static thing. I plan to work on them periodically, releasing updated versions and additional material in the future.Bitcoin is an inexhaustible teacher, which is why I do not claim that these lessons are all-encompassing or complete. They are a reflection of my personal journey down the rabbit hole. There are many more lessons to be learned, and every person will learn something different from entering the world of Bitcoin. I hope that you will find these lessons useful and that the process of learning them by reading won’t be as arduous and painful as learning them firsthand.

    Smith. But, thanks to the determination of a powerful senator, he would soon find himself at the agency’s helm. A Birkenstocks-wearing physics PhD, Jaczko was unlike any chairman the agency had ever seen: he was driven by a passion for technology and a concern for public safety, with no ties to the industry and no agenda other than to ensure that his agency made the world a safer place. And so Jaczko witnessed what outsiders like him were never meant to see—an agency overpowered by the industry it was meant to regulate and a political system determined to keep it that way. After an emergency trip to Japan to help oversee the frantic response to the horrifying nuclear disaster at Fukushima in 2011, and witnessing the American nuclear industry’s refusal to make the changes he considered necessary to prevent an equally catastrophic event from occurring here, Jaczko started saying aloud what no one else had dared. Confessions of a Rogue Nuclear Regulator is a wake-up call to the dangers of lobbying, the importance of governmental regulation, and the failures of congressional oversight. But it is also a classic tale of an idealist on a mission whose misadventures in Washington are astounding, absurd, and sometimes even funny—and Jaczko tells the story with humor, self-deprecation, and, yes, occasional bursts of outrage. Above all, Confessions of a Rogue Nuclear Regulator is a tale of confronting the truth about one of the most pressing public safety and environmental issues of our time: nuclear power will never be safe.

    But after epic highs, incredible lows,unforgettable scenery and unpronounceable place names, her simple idea turnsinto a compelling journey of self-discovery, and an eye-opening insight into whatmakes the island where she lives so special.

    But few of us understand the engineering mindset. It’s the mindset that came up with flatpack furniture, disposable nappies, and the postal code; that solved Stockholm’s traffic and the problem of bank closing times (the hole-in-the-wall); and whose seemingly simple ideas have saved countless lives, with innovations such as painting a line behind traffic lanes and combining GPS with 999. It’s a mindset much like a Swiss-army knife – multipurpose, combining structured and abstract thinking, common sense and great imagination, and cross-pollinating information from every possible sector.With the help of a cast of star engineers and fascinating, unexpected real world examples, Madhavan offers a framework for thinking creatively, systematically and strategically so that we can all learn to make better decisions in a complex world.

    But many of those bicycles disappear into basements and garages when the warm months end, parked there by owners fearful of the cold, snow and ice that winter brings. But does it have to be that way?Canadian writer and journalist Tom Babin started questioning this dogma after being stuck in winter commuter traffic one dreary and cold December morning and dreaming about the happiness that bicycle commuting had brought him all summer long. So he did something about it. He pulled on some thermal underwear, dragged his bike down from the rafters of his garage and set out on a mission to answer a simple but beguiling question: is it possible to happily ride a bike in winter? That question took him places he never expected. Over years of trial and error, research and more than his share of snow and ice, he discovered an unknown history of biking for snow and ice, and a new generation designed to make riding in winter safe and fun. He unearthed the world's most bike-friendly winter city and some new approaches to winter cycling from places all over the world. He also looked inward, to discover how the modern world shapes our attitudes toward winter. And perhaps most importantly, he discovered the unique kind of bliss that can only come by pedalling through softly falling snow on a quiet winter night.

    With elite cycling coach Chris Carmichael’s innovative, time-saving approach, busy cyclists will develop fitness, speed, and power in just 6 hours a week. Now powered by Strava, this updated third edition of The Time-Crunched Cyclist training program taps into the most popular cycling social network to help cyclists get fired up to crush their workouts, one segment at a time.Through his popular endurance coaching service, Carmichael noticed that many busy cyclists are unable to make performance gains using conventional training methods; they simply don’t have enough time to train. So CTS developed a new approach—the Time-Crunched Training Program—to help cyclists achieve competitive fitness and power without the impossible time demands of traditional training methods.The Time-Crunched Cyclist shows cyclists how to build fitness on a realistic schedule by tapping the power of high-intensity interval training (HIIT) workouts. Cyclists learn the science behind this alternative approach to training before performing the CTS field tests to get a baseline reading of their fitness. Nine comprehensive training plans include effective time-crunched workouts, nutrition guidelines, and strength training to develop the speed and endurance for a wide variety of cycling races and events. The new Time-Crunched Training Plans cover: · New and Experienced plans for criteriums, road races, and cyclocross· New, Experienced, and Competitive plans for century rides and Gran Fondos· Gravel racing and ultraendurance mountain biking plans· Intermediate and Advanced plans for commutersThis new, third edition integrates Strava, the popular ride tracking and analysis program. Powered by Strava, the Time-Crunched program becomes interactive, social, highly motivating—and focuses riders on the training data that matters most. It also adds the Time-Crunched Diet, a sports nutrition approach designed to help riders optimize their power-to-weight ratio with new guidelines on eating behaviors and delicious recipes from chefs Michael Chiarello and Matt Accarrino. A new chapter on hydration and managing heat stress will show athletes simple ways to avoid overheating that lead to better performance. The Time-Crunched Cyclist can help you capture your best performance—all in the time you have right now.

    We have learned little from the cataclysms of September 11 and Hurricane Katrina. When it comes to catastrophe, America is living on borrowed time-and squandering it. In this new book, leading security expert Stephen Flynn issues a call to action, demanding that we wake up and prepare immediately for a safer future. The truth is acts of terror cannot always be prevented, and nature continues to show its fury in frighteningly unpredictable ways. Resiliency, argues Flynn, must now become our national motto. With chilling frankness and clarity, Flynn paints an all too real scenario of the threats we face within our own borders. A terrorist attack on a tanker carrying liquefied natural gas into Boston Harbor could kill thousands and leave millions more of New Englanders without power or heat. The destruction of a ship with a cargo of oil in Long Beach, California, could bring the West Coast economy to its knees and endanger the surrounding population. But even these all-too-plausible terrorist scenarios pale in comparison to the potential destruction wrought by a major earthquake or hurricane. Our growing exposure to man-made and natural perils is largely rooted in our own negligence, as we take for granted the infrastructure handed down to us by earlier generations. Once the envy of the world, this infrastructure is now crumbling. After decades of neglect, our public health system leaves us at the mercy of microbes that could kill millions in the next flu pandemic. Flash flooding could wipe out a fifty-year-old dam north of Phoenix, placing thousands of homes and lives at risk. The next San Francisco earthquake could destroy century-old levees, contaminating the freshwater supply that most of California relies on for survival. It doesn't have to be this way. "The Edge of Disaster "tells us what we can do about it, as individuals and as a society. We can-and, Flynn argues, we must-construct a more resilient nation. With the wounds of recent national tragedies still unhealed, the time to act is now. Flynn argues that by tackling head-on, eyes open the perils that lie before us, we can remain true to our most important and endearing national trait: our sense of optimism about the future and our conviction that we can change it for the better for ourselves-and our children. "Steve Flynn offers the answer not only to protecting America from terrorist attacks and natural disaster but also to revitalizing our democracy. This book is a must-read for all members of Congress, 2008 presidential candidates, and ordinary citizens who want to build a better and safer future."-Anne-Marie Slaughter, dean, Woodrow Wilson School of Public and International Affairs, Princeton University Advance praise for "The Edge of Disaster" "Steve Flynn has done it again. Like America the Vulnerable before it, "The Edge of Disaster" is the must-read book for every American, elected official, and presidential candidate who is committed to ensuring that our nation continue to thrive in perilous times."-Mark Warner, former governor of Virginia "Since 9/11, protecting our nation against a terrorist attack has consumed policy makers in Washington. What Stephen Flynn points out in The Edge of Disaster is that much of this effort has been directed overseas, often at the expense of our homeland and its much more likely areas of vulnerability. Laying out a series of potential disasters both manmade and natural, Flynn calls for a greater emphasis on preparedness and the ability of communities and the nation to recover. Painting an often frustrating and infuriating picture of missed opportunities, "The Edge of Disaster "is a call to action. The time to act is now. We can only hope that policy makers are listening." -Christine Todd Whitman, former governor of New Jersey and former administrator, Environmental Protection Agency (2001-03) "Steve Flynn's book makes the very persuasive argument that national security preparedness is linked to natural disaster preparedness. By investing significantly in our critical infrastructure, in citizen preparedness, and most importantly in leadership, we can be better prepared for all hazards. A great book that I highly recommend." -James Lee Witt, former director, Federal Emergency Management Agency "Steve Flynn has become a relentless contributor to the dialogue on prioritizing the work of the post-9/11 security environment. "The Edge of Disaster" calls into question the neglect of domestic preparedness in favor of the Department of Defense-driven offensive in the global war on terrorism. The book offers provocative challenges to both our elected and our private-sector leaders, and both should read it thoroughly." -Admiral James M. Loy, former commandant, U.S. Coast Guard, and former deputy secretary of homeland security
