When you're a kid, all you want to do is skate. Jobs, rent, relationships, student loans, "your future," whether or not the door person at the bar you're going to after skating will let you in with your board--none of these things matter. As you get older there are more things to worry about and less time to take care of them all. Everyone reaches a point when they can no longer skate for 10 hours straight. Being a kid pushing around the city with little concern for time, you learn to make your money stretch. When your pockets only contain some loose change, a Metrocard, and nuggets of wax, the quarter snack from the bodega is the most viable option. Once you can afford actual meals and overpriced New York rent, the quarter snack becomes a symbol of a simpler time, back when you were content with skating on a diet that could lead to diabetes if not phased out by 19. That's when things were a lot more fun. Quartersnacks, an online epicenter for the skate culture of downtown New York, never cared about "best-of-the-best skateboarding." Instead, with acute self-awareness and biting humor, it chronicles the exploits of everyone bound together by a common interest in skateboarding in New York. Life isn't a high school movie where a crew of the best skaters in town exclusively skates together and terrorizes the losers. In New York everyone skates with everyone else--"talent" is secondary. Quartersnacks captures the energy of a session in the city with your childhood friends, some younger kids you just met just last year when they moved here for college, their friends visiting from out of town, and some token pros, all skating together. In the ten years that Quartersnacks has been active, New York has become a national hub for skateboarding (at least in the warm months) and more kids are skating worldwide than ever. TF at 1: Ten Years of Quartersnackscollects the best and worst from the site, along with new interviews, and documentation of the spots, the videos, the shops, and everything else that has changed and remained the same in New York skating in the past decade.

Seven-year-old Alex starts to lose her baby teeth, begins a correspondence with the Tooth Fairy, and tries to accept the fact that her family is moving to a distant state.

Through a series of recent breakthroughs, deep learning has boosted the entire field of machine learning. Now, even programmers who know close to nothing about this technology can use simple, efficient tools to implement programs capable of learning from data. This practical book shows you how. By using concrete examples, minimal theory, and two production-ready Python frameworks—Scikit-Learn and TensorFlow—author Aurélien Géron helps you gain an intuitive understanding of the concepts and tools for building intelligent systems. You’ll learn a range of techniques, starting with simple linear regression and progressing to deep neural networks. With exercises in each chapter to help you apply what you’ve learned, all you need is programming experience to get started. Explore the machine learning landscape, particularly neural nets Use Scikit-Learn to track an example machine-learning project end-to-end Explore several training models, including support vector machines, decision trees, random forests, and ensemble methods Use the TensorFlow library to build and train neural nets Dive into neural net architectures, including convolutional nets, recurrent nets, and deep reinforcement learning Learn techniques for training and scaling deep neural nets

This book presents a comprehensive overview of the recent advances in the domain of optimal guidance, exploring the characteristics of various optimal guidance algorithms and their pros and cons. Optimal guidance is based on the concept of trajectory optimization, which minimizes the meaningful performance index while satisfying certain terminal constraints, and by properly designing the cost function the guidance command can serve as a desired pattern for a variety of mission objectives. The book allows readers to gain a deeper understanding of how optimal guidance law can be utilized to achieve different mission objectives for missiles and UAVs, and also explores the physical meaning and working principle of different new optimal guidance laws. In practice, this information is important in ensuring confidence in the performance and reliability of the guidance law when implementing it in a real-world system, especially in aerospace engineering where reliability is the first priority.

A history of comic books from the 1930s to 9/11.

We all want to look and feel good. We also want to perform well whether it's in the weight room, in sports, or at work. Research has shown exercise, proper nutrition, and adequate recovery affect health and human performance. However, there's lot of conflicting and confusing information regarding exercise and nutrition. In Essentials of Exercise and Sport Nutrition, author Dr. Richard B. Kreider offers an up-to-date assessment of the science and practice of exercise and sport nutrition. Kreider, who has conducted extensive research on the subject and has consulted with numerous teams, coaches, and athletes for more than thirty years, brings a scientific and applied perspective to discussing the latest research and how it can be used to optimize performance. He also provides summary recommendations, training programs, and meal plans for beginners through athletes, as well as for individuals who want to lose and/or manage their weight.
