The best way to learn the Linux command line is as a series of small, easy to manage steps. This book is organized as such, with each section building upon the knowledge and skills learned in the previous sections. If you work through them in order, read them fully (there is a fair bit of material but it is important for getting a proper understanding) and practice on the command line as you go I believe you should have a fairly pleasant and smooth journey to Linux command line mastery. 99 times out of 100 when a student has troubles with this stuff, I find that it is not that they are incapable but that they were lazy and didn't read the material fully. Each section is structured in the following format:An introduction outlining what you will learn in that sectionDetailed material including extensive examplesA summary of programs covered in that section and the most important conceptsA set of activities to help you solidify your knowledge and skills Think of the activities not as tutorial questions (such as you may get in a class at school) but as direction on where to explore in the Linux environment to benefit from your new knowledge and skills. Treat the activities as a starting point for exploration. The further you take it, the better you will do. (How well you do and how far you go depends on how unlazy you are.)Show book
A history of the development of world maps during the later medieval period in the centuries leading up to Columbus’s journey. In the two centuries before Columbus, mapmaking was transformed. The World Map, 1300–1492 investigates this important, transitional period of mapmaking. Beginning with a 1436 atlas of ten maps produced by Venetian Andrea Bianco, Evelyn Edson uses maps of the fourteenth and fifteenth centuries to examine how the discoveries of missionaries and merchants affected the content and configuration of world maps. She finds that both the makers and users of maps struggled with changes brought about by technological innovation?the compass, quadrant, and astrolabe?rediscovery of classical mapmaking approaches, and increased travel. To reconcile the tensions between the conservative and progressive worldviews, mapmakers used a careful blend of the old and the new to depict a world that was changing?and growing?before their eyes. This engaging and informative study reveals how the ingenuity, creativity, and adaptability of these craftsmen helped pave the way for an age of discovery. “A comprehensive and complex picture of the changing face of medieval geography. With the mastery of a formidable palette of historiographic knowledge and well-reasoned discussions of the sources, The World Map, 1300–1492 will certainly remain an important work to consult for both medieval and early modern scholars for many years to come.” —Ian J. Aebel, Terrae IncognitaeShow book
How math can make a more stable democracy: “A breath of fresh air . . . a reaffirmation that mathematics should be used more often to make general public policy.” —MAA Reviews How should we count the population of the United States? What would happen if we replaced the electoral college with a direct popular vote? What are the consequences of allowing unlimited partisan gerrymandering of congressional districts? Can six-person juries yield verdicts consistent with the needs of justice? Is it racist to stop and frisk minorities at a higher rate than non-minorities? These and other questions have long been the subject of legal and political debate and are routinely decided by lawyers, politicians, judges, and voters, mostly through an appeal to common sense and tradition. But mathematician Jeff Suzuki asserts that common sense is not so common, and traditions developed long ago in what was a mostly rural, mostly agricultural, mostly isolated nation of three million might not apply to a mostly urban, mostly industrial, mostly global nation of three hundred million. In Constitutional Calculus, Suzuki guides us through the U.S. Constitution and American history to show how mathematics reveals our flaws, finds the answers we need, and moves us closer to our ideals. From the first presidential veto to the debate over mandatory drug testing, the NSA’s surveillance program, and the fate of death row inmates, Suzuki draws us into real-world debates and then reveals how math offers a superior compass for decision-making. Relying on iconic cases, including the convictions of the Scottsboro boys, League of United Latin American Citizens v. Perry, and Floyd v. City of New York, Suzuki shows that more math can lead to better justice, greater fairness, and a more stable democracy.Show book

Written for everyone fascinated by the huge beasts that once roamed the earth, this book introduces the giant hornless rhinoceros, Indricotherium. These massive animals inhabited Asia and Eurasia for more than 14 million years, about 37 to 23 million years ago. They had skulls six feet long, stood twenty-two feet high at the shoulder, and were twice as heavy as the largest elephant ever recorded, tipping the scales at 44,100 pounds. Fortunately, the big brutes were vegetarians. Donald R. Prothero tells their story, from their discovery just a century ago to the latest research on how they lived and died.Show book
