This hands-on guide demonstrates how the flexibility of the command line can help you become a more efficient and productive data scientist. You?ll learn how to combine small, yet powerful, command-line tools to quickly obtain, scrub, explore, and model your data. To get you started?whether you?re on Windows, OS X, or Linux?author Jeroen Janssens introduces the Data Science Toolbox, an easy-to-install virtual environment packed with over 80 command-line tools. Discover why the command line is an agile, scalable, and extensible technology. Even if you?re already comfortable processing data with, say, Python or R, you?ll greatly improve your data science workflow by also leveraging the power of the command line. * Obtain data from websites, APIs, databases, and spreadsheets * Perform scrub operations on plain text, CSV, HTML/XML, and JSON * Explore data, compute descriptive statistics, and create visualizations * Manage your data science workflow using Drake * Create reusable tools from one-liners and existing Python or R code * Parallelize and distribute data-intensive pipelines using GNU Parallel * Model data with dimensionality reduction, clustering, regression, and classification algorithms
Data-governance programs focus on authority and accountability for the management of data as a valued organizational asset. Data Governance should not be about command-and-control, yet at times could become invasive or threatening to the work, people and culture of an organization. Non-Invasive Data Governance(TM) focuses on formalizing existing accountability for the management of data and improving formal communications, protection, and quality efforts through effective stewarding of data resources. Non-Invasive Data Governance will provide you with a complete set of tools to help you deliver a successful data governance program. Learn how: Steward responsibilities can be identified and recognized, formalized, and engaged according to their existing responsibility rather than being assigned or handed to people as more work. Governance of information can be applied to existing policies, standard operating procedures, practices, and methodologies, rather than being introduced or emphasized as new processes or methods. Governance of information can support all data integration, risk management, business intelligence and master data management activities rather than imposing inconsistent rigor to these initiatives. A practical and non-threatening approach can be applied to governing information and promoting stewardship of data as a cross-organization asset. Best practices and key concepts of this non-threatening approach can be communicated effectively to leverage strengths and address opportunities to improve.
Bridges the gap between SAS and R, allowing users trained in one language easily learn the other. SAS and R are widely-used, very different software environments. Prized for its statistical and graphical tools, R is an open-source programming language that is popular with statisticians and data miners who develop statistical software and analyze data. SAS (Statistical Analysis System) is the leading corporate software in analytics thanks to its faster data handling and smaller learning curve. SAS for R Users enables entry-level data scientists to take advantage of the best aspects of both tools by providing a cross-functional framework for users who already know R but may need to work with SAS. Those with knowledge of both R and SAS are of far greater value to employers, particularly in corporate settings. Using a clear, step-by-step approach, this book presents an analytics workflow that mirrors that of the everyday data scientist. This up-to-date guide is compatible with the latest R packages as well as SAS University Edition. Useful for anyone seeking employment in data science, this book: Instructs both practitioners and students fluent in one language seeking to learn the other Provides command-by-command translations of R to SAS and SAS to R Offers examples and applications in Both R and SAS Presents step-by-step guidance on workflows, color illustrations, sample code, chapter quizzes, and more Includes sections on advanced methods and applications Designed for professionals, researchers, and students, SAS for R Users is a valuable resource for those with some knowledge of coding and basic statistics who wish to enter the realm of data science and business analytics.
Androiden greifen an! Auf dem Planeten Galor V ist ein neuer Androiden-Prototyp entwickelt worden, der über künstliche Intelligenz verfügt. Doch bei einem Test stürzt das Labor ein. Die Enterprise soll den Vorfall untersuchen. Commander Data entdeckt Anzeichen dafür, dass es sich bei dem Unfall in Wirklichkeit um einen Anschlag gehandelt hat. Bei seinen Nachforschungen stößt die Enterprise-Crew auf eine unterirdische Station, die von riesigen Androiden bewacht wird. In letzter Sekunde kann das Einsatzteam entkommen - doch dann taucht plötzlich eine ganze Flotte von Androiden-Schiffen auf und greift die Enterprise an. Captain Picard kann ihren überlegenen Waffen nichts entgegensetzen.

Shell scripting skills never go out of style. It´s the shell that unlocks the real potential of Unix. Shell scripting is essential for Unix users and system administrators-a way to quickly harness and customize the full power of any Unix system. With shell scripts, you can combine the fundamental Unix text and file processing commands to crunch data and automate repetitive tasks. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. Classic Shell Scripting is written to help you reliably navigate these tricky waters. Writing shell scripts requires more than just a knowledge of the shell language, it also requires familiarity with the individual Unix programs: why each one is there, how to use them by themselves, and in combination with the other programs. The authors are intimately familiar with the tips and tricks that can be used to create excellent scripts, as well as the traps that can make your best effort a bad shell script. With Classic Shell Scripting you´ll avoid hours of wasted effort. You´ll learn not only write useful shell scripts, but how to do it properly and portably.The ability to program and customize the shell quickly, reliably, and portably to get the best out of any individual system is an important skill for anyone operating and maintaining Unix or Linux systems. Classic Shell Scripting gives you everything you need to master these essential skills.
