Suitable for the British Canoe Union navigation courses, this work for sea kayakers covers GPS, reflecting the increased availability and usage of electronic navigational aids. It also includes colour photos, diagrams, maps, and charts, as well as exercises to reinforce and self-assess at the end of each chapter.
Serving as a manual for intermediate and advanced sea kayakers, this book covers topics of kayaking history, physiology, boat and paddle dynamics, seamanship and navigation, safety and rescue, weather forecasting, caves, rockhopping and tidal races, expeditions and overnighting, as well as a wealth of tips and resources for the sea paddler.
´´We´re all safer when the systems we depend upon are inspectable, auditable, and documented - and this definitely includes cars.´´ - Chris Evans, hacker and founder of Project Zero Modern cars are more computerized than ever. Infotainment and navigation systems, Wi-Fi, automatic software updates, and other innovations aim to make driving more convenient. But vehicle technologies haven´t kept pace with today´s more hostile security environment, leaving millions vulnerable to attack. The Car Hacker´s Handbook will give you a deeper understanding of the computer systems and embedded software in modern vehicles. It begins by examining vulnerabilities and providing detailed explanations of communications over the CAN bus and between devices and systems. Then, once you have an understanding of a vehicle´s communication network, you´ll learn how to intercept data and perform specific hacks to track vehicles, unlock doors, glitch engines, flood communication, and more. With a focus on low-cost, open source hacking tools such as Metasploit, Wireshark, Kayak, can-utils, and ChipWhisperer, The Car Hacker´s Handbook will show you how to: - Build an accurate threat model for your vehicle - Reverse engineer the CAN bus to fake engine signals - Exploit vulnerabilities in diagnostic and data-logging systems - Hack the ECU and other firmware and embedded systems - Feed exploits through infotainment and vehicle-to-vehicle communication systems - Override factory settings with performance-tuning techniques - Build physical and virtual test benches to try out exploits safely If you´re curious about automotive security and have the urge to hack a two-ton computer, make The Car Hacker´s Handbook your first stop.
Long before GPS, Google Earth, and global transit, humans traveled vast distances using only environmental clues and simple instruments. John Huth asks what is lost when modern technology substitutes for our innate capacity to find our way. Encyclopedic in breadth, weaving together astronomy, meteorology, oceanography, and ethnography, The Lost Art of Finding Our Way puts us in the shoes, ships, and sleds of early navigators for whom paying close attention to the environment around them was, quite literally, a matter of life and death. Haunted by the fate of two young kayakers lost in a fogbank off Nantucket, Huth shows us how to navigate using natural phenomena - the way the Vikings used the sunstone to detect polarization of sunlight, and Arab traders learned to sail into the wind, and Pacific Islanders used underwater lightning and ´read´ waves to guide their explorations. Huth reminds us that we are all navigators capable of learning techniques ranging from the simplest to the most sophisticated skills of direction-finding. Even today, careful observation of the sun and moon, tides and ocean currents, weather and atmospheric effects can be all we need to find our way. Lavishly illustrated with nearly 200 specially prepared drawings, Huth´s compelling account of the cultures of navigation will engross readers in a narrative that is part scientific treatise, part personal travelogue, and part vivid re-creation of navigational history. Seeing through the eyes of past voyagers, we bring our own world into sharper view.
