KDE is one of the biggest Free Software communities in the world. Since its founding 20 years ago, it has achieved remarkeable things. In this book 37 of the people who made it happen tell their story and what makes KDE so special. Let us take you on a ride through 20 years of KDE - what we achieved in the past, where we are now and what the future holds for us.
A Pulitzer Prize nominee offers the most practical advice for beginning KDE users, including installation and daily use.

Ever imagined how to become an expert at effectively approaching data analysis problems, solving them, and extracting all of the available information from your data? Well, look no further, this is the book you want! Through this comprehensive guide, you will explore data and present results and conclusions from statistical analysis in a meaningful way. You'll be able to quickly and accurately perform the hands-on sorting, reduction, and subsequent analysis, and fully appreciate how data analysis methods can support business decision-making. You'll start off by learning about the tools available for data analysis in Python and will then explore the statistical models that are used to identify patterns in data. Gradually, you'll move on to review statistical inference using Python, Pandas, and SciPy. After that, we'll focus on performing regression using computational tools and you'll get to understand the problem of identifying clusters in data in an algorithmic way. Finally, we delve into advanced techniques to quantify cause and effect using Bayesian methods and you'll discover how to use Python's tools for supervised machine learning. Style and approach This book takes a step-by-step approach to reading, processing, and analyzing data in Python using various methods and tools. Rich in examples, each topic connects to real-world examples and retrieves data directly online where possible. With this book, you are given the knowledge and tools to explore any data on your own, encouraging a curiosity befitting all data scientists.

Forget the 10,000 hour rule— what if it’s possible to learn the basics of any new skill in 20 hours or less? Take a moment to consider how many things you want to learn to do. What’s on your list? What’s holding you back from getting started? Are you worried about the time and effort it takes to acquire new skills—time you don’t have and effort you can’t spare? Research suggests it takes 10,000 hours to develop a new skill. In this nonstop world when will you ever find that much time and energy? To make matters worse, the early hours of prac­ticing something new are always the most frustrating. That’s why it’s difficult to learn how to speak a new language, play an instrument, hit a golf ball, or shoot great photos. It’s so much easier to watch TV or surf the web . . . In The First 20 Hours, Josh Kaufman offers a systematic approach to rapid skill acquisition— how to learn any new skill as quickly as possible. His method shows you how to deconstruct com­plex skills, maximize productive practice, and remove common learning barriers. By complet­ing just 20 hours of focused, deliberate practice you’ll go from knowing absolutely nothing to performing noticeably well. Kaufman personally field-tested the meth­ods in this book. You’ll have a front row seat as he develops a personal yoga practice, writes his own web-based computer programs, teaches himself to touch type on a nonstandard key­board, explores the oldest and most complex board game in history, picks up the ukulele, and learns how to windsurf. Here are a few of the sim­ple techniques he teaches: Define your target performance level: Fig­ure out what your desired level of skill looks like, what you’re trying to achieve, and what you’ll be able to do when you’re done. The more specific, the better. Deconstruct the skill: Most of the things we think of as skills are actually bundles of smaller subskills. If you break down the subcompo­nents, it’s easier to figure out which ones are most important and practice those first. Eliminate barriers to practice: Removing common distractions and unnecessary effort makes it much easier to sit down and focus on deliberate practice. Create fast feedback loops: Getting accu­rate, real-time information about how well you’re performing during practice makes it much easier to improve. Whether you want to paint a portrait, launch a start-up, fly an airplane, or juggle flaming chain­saws, The First 20 Hours will help you pick up the basics of any skill in record time . . . and have more fun along the way.

While the fall of the Berlin Wall is positively commemorated in the West, the intervening years have shown that the former Soviet Bloc has a more complicated view of its legacy. In post-communist Eastern Europe, the way people remember state socialism is closely intertwined with the manner in which they envision historical justice. Twenty Years After Communism is concerned with the explosion of a politics of memory triggered by the fall of state socialism in Eastern Europe, and it takes a comparative look at the ways that communism and its demise have been commemorated (or not commemorated) by major political actors across the region. The book is built on three premises. The first is that political actors always strive to come to terms with the history of their communities in order to generate a sense of order in their personal and collective lives. Second, new leaders sometimes find it advantageous to mete out justice on the politicians of abolished regimes, and whether and how they do so depends heavily on their interpretation and assessment of the collective past. Finally, remembering the past, particularly collectively, is always a political process, thus the politics of memory and commemoration needs to be studied as an integral part of the establishment of new collective identities and new principles of political legitimacy. Each chapter takes a detailed look at the commemorative ceremony of a different country of the former Soviet Bloc. Collectively the book looks at patterns of extrication from state socialism, patterns of ethnic and class conflict, the strategies of communist successor parties, and the cultural traditions of a given country that influence the way official collective memory is constructed. Twenty Years After Communism develops a new analytical and explanatory framework that helps readers to understand the utility of historical memory as an important and understudied part of democratization.
Education has fought long and hard to gain acceptance as a profession and, since professionals by definition use data to shape the decisions they make, education has little choice but to continue moving in this direction. This 3-part handbook represents a major contribution to the literature of education. It is a unique compendium of the most original work currently available on how, when and why evidence should be used to ground practice. It is a comprehensive, cross-disciplinary, research-based, and practice-based resource that all educators can turn to as a guide to data-based decision making. The Handbook of Data-Based Decision Making in Education is a must read for researchers who are just beginning to explore the scientifically based nature of educational practice. It is also appropriate for policy makers and practitioners who are confronted with young people who need to be in classrooms where "best practices" are the norm and not the exception.
