| do math in bash: Bash Cookbook Carl Albing, JP Vossen, Cameron Newham, 2007-05-24 The key to mastering any Unix system, especially Linux and Mac OS X, is a thorough knowledge of shell scripting. Scripting is a way to harness and customize the power of any Unix system, and it's an essential skill for any Unix users, including system administrators and professional OS X developers. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. bash Cookbook teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficient user of the most common Unix shell -- the bash shell -- and cygwin or other popular Unix emulation packages. Packed full of useful scripts, along with examples that explain how to create better scripts, this new cookbook gives professionals and power users everything they need to automate routine tasks and enable them to truly manage their systems -- rather than have their systems manage them. |

The following description contains spoilers for the first book. What’s the point of being a princess if the whole kingdom hates you? Being a royal should make my life easier, but it only compounds my problems. When my father, the new King of Valora, succeeded the beloved King Tiberius, many of his subjects believed he killed my uncle just to gain the throne. His new policies only make the people hate him more. Just my luck, they transfer their loathing onto me. Even my best friend and my boyfriend aren’t enough of a buffer, and I’m continually fending off verbal, and sometimes physical, attacks. That’s when my powers start growing… When no one at the academy can—or will—help me learn about my new abilities, I begin to research them on my own. Modern answers seem to be entwined with a terrifying ancient legend. If the lore is true, my destiny is far more tragic than my present problems. And I don’t know if I can change it. Or if I should even try. |

| do math in bash: The Monsters Know What They're Doing Keith Ammann, 2019-10-29 From the creator of the popular blog The Monsters Know What They’re Doing comes a compilation of villainous battle plans for Dungeon Masters. In the course of a Dungeons & Dragons game, a Dungeon Master has to make one decision after another in response to player behavior—and the better the players, the more unpredictable their behavior! It’s easy for even an experienced DM to get bogged down in on-the-spot decision-making or to let combat devolve into a boring slugfest, with enemies running directly at the player characters and biting, bashing, and slashing away. In The Monsters Know What They’re Doing, Keith Ammann lightens the DM’s burden by helping you understand your monsters’ abilities and develop battle plans before your fifth edition D&D game session begins. Just as soldiers don’t whip out their field manuals for the first time when they’re already under fire, a DM shouldn’t wait until the PCs have just encountered a dozen bullywugs to figure out how they advance, fight, and retreat. Easy to read and apply, The Monsters Know What They're Doing is essential reading for every DM. |

| do math in bash: Student Voice in School Reform Dana L. Mitra, 2014-03-14 High schools continue to be places that isolate, alienate, and disengage students. But what would happen if students were viewed as part of the solution in schools rather than part of the problem? This book examines the emergence of student voice at one high school in the San Francisco Bay area where educators went straight to the source and asked the students to help. Struggling, like many high schools, with how to improve student outcomes, educators at Whitman High School decided to invite students to participate in the reform process. Dana L. Mitra describes the evolution of student voice at Whitman, showing that the students enthusiastically created partnerships with teachers and administrators, engaged in meaningful discussion about why so many failed or dropped out, and partnered with teachers and principals to improve learning for themselves and their peers. In documenting the difference that student voice made, this book helps expand ideas of distributed leadership, professional learning communities, and collaboration. The book also contributes much needed research on what student voice initiatives look like in practice and provides powerful evidence of ways in which young people can increase their sense of agency and their sense of belonging in school. |
