  Learn Robotics and ROS 2 with Practical Examples
  Book Description
  Robot Operating System (ROS) and Python are essential tools for developing advanced robotics applications, offering reliability and scalability for both research and industrial solutions. Ultimate Robotics Programming with ROS 2 and Python introduces readers to ROS 2 without requiring prior experience in robotics. It blends theoretical explanations with practical exercises, empowering readers to solve specific robotics problems while understanding the reasoning behind various approaches.
  The book covers a broad spectrum of robotics topics, including mobile robots, industrial manipulators, and aerial robots. These systems are simulated using the modern Gazebo simulator and programmed with ROS 2’s out-of-the-box tools and custom solutions using the ROS 2 API. The book also delves into computer vision, generative AI, and machine learning, providing hands-on examples of real-world applications.

  Four Thousand Hooks - A True...

  As Four Thousand Hooks opens, an Alaskan fishing schooner is sinking. It is the summer of 1972, and the sixteen-year-old narrator is at the helm. Backtracking from the gripping prologue, Dean Adams describes how he came to be a crew member on the Grant and weaves a tale of adventure that is like a novel—with drama, conflict, and resonant portrayals of halibut fishing, his ragtag shipmates, maritime Alaska, and the ambiguities of family life. 
   
   
   
  At sea, the Grant's crew teach Dean the daily tasks of baiting thousands of longline hooks and handling the catch, and on shore they lead him through the seedy bars and guilty pleasures of Kodiak. Exhausted by twenty-hour workdays and awed by the ocean's raw power, he observes examples of human courage and vulnerability and emerges with a deeper knowledge of himself and the world. 
   
   
   
  Four Thousand Hooks is both an absorbing adventure story and a rich ethnography of a way of life and work that has sustained Northwest families for generations. This coming of age story will appeal to listeners including young adults and anyone interested in ocean adventures, commercial fishing, maritime life, and the Northwest coast.

  Parasitology - How These Tiny...

  Parasites are among the most successful and adaptable organisms on Earth, yet they often go unnoticed. From microscopic protozoa to large intestinal worms, these creatures have evolved remarkable strategies to exploit their hosts for survival. They infiltrate nearly every ecosystem, from the deepest oceans to the highest mountains, shaping the health, behavior, and evolution of countless species, including humans. Despite their negative reputation, parasites play an integral role in maintaining ecological balance, influencing biodiversity, and even driving evolutionary changes. 
  One of the most astonishing aspects of parasites is their sheer ubiquity. They infect nearly every living organism, from plants and insects to birds and mammals. Some parasites, like malaria-causing Plasmodium, have coexisted with humans for thousands of years, evolving alongside us in an ongoing battle for survival. Others, such as the toxoplasmosis-causing Toxoplasma gondii, subtly manipulate the behavior of their hosts to improve their chances of transmission. The ability of parasites to adapt to new environments and hosts makes them a fascinating subject of study, particularly as climate change and globalization increase their spread. 
  While parasites are often viewed as destructive, their influence extends far beyond causing disease. Many parasites regulate host populations, preventing overgrowth and maintaining ecological stability. Some even shape the behaviors of their hosts in ways that benefit entire ecosystems.

  Following on from the hugely popular Treasury of Folklore: Seasand Rivers and Woodlands and Forests comes Treasury of Folklore: Stars and Skies, an exploration of the mysteries of the stars, skies and heavens above.
  People have gazed up at the same stars for millennia, trading stories about them; conjuring gods and goddesses; mapping the constellations; and navigating the complex human world below. The tales, traditions and myths included here traverse countries and continents and have been chosen to highlight how humans are linked through time and place, with shared dreams, fears and ways of rationalising the unknown.
  Under 'Stars and Heavens' Willow delves into rosy fingered dawn and the hubris of Icarus, the Greek myths surrounding the constellations and the omen of meteors, the trials of the Hawaiian goddess Hina and the legend of the rabbit in the moon. In the section on 'Skies' we are introduced to winged Pegasus and the Firebird, the Witch of Westray and stories of storms, the mysteries of the Northern Lights and unexplained UFOs. 
  Treasury of Folklore: Stars and Skies is a fascinating portal into a rich history of myths surrounding the sky, an aspect of the natural world that continues to fascinate and confound.

  The Devil Takes Bitcoin -...

  From the author of Tokyo Vice comes the wild, true story of cyber-era commerce, crime, cold-hard cash, and one of the greatest heists in history. 
   
  Even in hell, Bitcoin talks. This modern take on an old Japanese saying still holds true. Cryptocurrency was supposed to do for money what the internet did for information, but it didn't work out that way. Its virtual existence unleashed real-world chaos―especially in the homeland of its mysterious creator, Satoshi Nakamoto. Tokyo was the center of the world's largest Bitcoin exchange, Mt. Gox, until that company collapsed with nearly half a billion dollars' worth of Bitcoin gone missing. It might be the greatest heist in history. If it was a heist. 
   
  So what really happened? The Devil Takes Bitcoin tells the true story of the humble-to-hot commodity, from the former geek website that launched the boom to an inside world of absent-minded CEOs, hucksters, hackers, cybercrooks, drug dealers, corrupt federal agents, evangelical libertarians, and clueless techies. You'll discover Bitcoin's connection to the infamous Silk Road, learn why hell has nothing on Japan's criminal justice system, and get the lowdown on the high cost of betting with the Devil's dollars. All of this for less than the price of a single Bitcoin.
