  Cryptography in World War I: The...

  World War I was the first major conflict in which new electronic means of transmitting and receiving messages became a major factor in political and military operations. The electric telegraph was developed in the first half of the 19th century, and by 1850, there were several telegraph companies around the world providing a service that allowed virtually instantaneous communication over long distances. This was a major breakthrough, but the telegraph depended on the availability of wires to transmit messages between stations, meaning that if these wires were broken or damaged, communications were cut off. 
  	Late in the 19th century, there was another new development, the telephone, though this too relied on wires to transmit and receive information. At the same time, there was a new invention that provided instant voice and Morse code communication over long distances that did not require wires. Initially called wireless, radio was quickly adopted by armies around the world as a way of providing rapid communication between military units. By the time World War I began in 1914, all the major nations involved had provided their forces with some form of radio equipment. 
  	Of course, this came with a fundamental problem: radio, telephone, and telegraph messages could be intercepted by the enemy, potentially giving them notice of impending operations. To protect these electronic messages from being read by the enemy, armies began to use codes and ciphers to disguise the meaning of messages. Teams were created to devise effective codes and ciphers, and these were quickly followed by other teams whose role was to attempt to break the codes and ciphers used by the other side. As a result, a secret war began, almost completely hidden from public view, as the belligerents devised complex ways of hiding the real meaning of their own messages while simultaneously attempting to understand those of the enemy.

  Sally Douglas and Imogen Carn met after the sudden deaths of their mothers only months apart.

  Monks and Bishops - Lismore...

  Robert Hay

  • 0

  The Isle of Lismore has a long reputation as a holy island, beginning with the foundation of a monastery by St Moluag in the sixth century, when it became a major centre of Christianity. The Roman Catholic Bishopric of Argyll was founded on Lismore in 1200, and the medieval Cathedral Church of St Moluag was completed in 1400, the choir of which forms the basis of the present-day parish church.
  Robert Hay tells the story of Moluag's monastery, recently rediscovered by community archaeology, before exploring the rise and fall of the Bishopric of Argyll: the roles of the bishops; the years of prestige when leading families invested in elaborately carved graveslabs; the lean years when finances were strained; the struggles through decades of war, civil unrest, despoliation, famine and plague; and the final withdrawal of the bishop from Lismore to Dunoon in the mid fifteenth century. Even at the physical fringes of Scotland and Europe, the diocese was deeply affected by events on the national and international scene, with a major impact on this site of an unbroken tradition of Christian worship.

  Leadership is often talked about—but rarely understood. 
  Extreme Leadership cuts through the jargon and theory to show what real leadership looks like under pressure. With clarity, edge, and real-world insight, Charles Patton delivers a direct, no-nonsense guide for those who want to lead—and get results. 
  Leadership isn't about titles, org charts, or abstract models. It's about stepping up when it counts, seeing what others miss, and taking action when others hesitate. Drawing from bold examples and practical lessons, this book explores how extreme leaders think, respond, and succeed—even in chaotic, high-stakes environments. 
  Written as a supplement to graduate-level courses but accessible to anyone with a stake in leading or following, this book challenges the idea that leadership is soft, outdated, or optional. It's not. It's essential. 
  If you want the things great people have, you must do the things great leaders do. This book shows you how.
