Graphical user interfaces lowered the barrier to using computers for many people and enabled new applications. However, in software development and system administration, Command Line Interfaces (CLIs) are still widely used. Users input text commands individually in a command line interface, often receiving a text output after each executed command. Terminal User Interfaces (TUIs) are used by interactive programs while operating within a text-based terminal. Think of two-pane file managers or text editors that work over the whole terminal screen. There are several text-based shells that we can use, but the most common and useful to know is Bourne Again SHell, known as Bash. It is the shell commonly associated with Linux since it is installed by default on most Linux distributions, such as Ubuntu or Fedora. Another popular shell is Z shell (Zsh), now the default shell on macOS. While Bash is an excellent choice for scripting thanks to its ubiquity, Zsh is used by developers and sysadmins for its interactivity and configurability. Fish shell is also gaining popularity, being designed to be a user-friendly shell with good defaults. However, it is less compatible with the other mentioned shells. Windows operating system also has its shell called PowerShell. For software developers, sysadmins and data scientists. For anyone who needs to control Linux or BSD systems like personal computers, servers, virtual machines and containers.

Название: An Introduction to Spatial Data Science with GeoDa, Volume 1: Exploring Spatial Data
Автор: Luc Anselin
Издательство: CRC Press
Год: 2024
Страниц: 453
Язык: английский
Формат: pdf (true)
Размер: 20.4 MB

This book is the first in a two-volume series that introduces the field of Spatial Data Science. It offers an accessible overview of the methodology of exploratory spatial data analysis. It also constitutes the definitive user’s guide for the widely adopted GeoDa open-source software for spatial analysis. Leveraging a large number of real-world empirical illustrations, readers will gain an understanding of the main concepts and techniques, using dynamic graphics for thematic mapping, statistical graphing, and, most centrally, the analysis of spatial autocorrelation. Key to this analysis is the concept of local indicators of spatial association, pioneered by the author and recently extended to the analysis of multivariate data. The focus of the book is on intuitive methods to discover interesting patterns in spatial data. It offers a progression from basic data manipulation through description and exploration to the identification of clusters and outliers by means of local spatial autocorrelation analysis. A distinctive approach is to spatialize intrinsically non-spatial methods by means of linking and brushing with a range of map representations, including several that are unique to the GeoDa software. The book also represents the most in-depth treatment of local spatial autocorrelation and its visualization and interpretation by means of GeoDa. The libgeoda library has a clearly defined Application Programming Interface (API), which allows other C++ code to access its functionality directly. In fact, this is what currently happens under the hood for part of desktop GeoDa, and in the experimental web-GeoDa (jsgeoda, implemented through jаvascript). In addition to achieving a more flexible interaction with different graphical user interface implementations, the API also allows other software, such as R or Python programs to access the functionality through well-defined wrapper code.

This book is the second in a two-volume series that introduces the field of spatial Data Science. It moves beyond pure data exploration to the organization of observations into meaningful groups, i.e., spatial clustering. This constitutes an important component of so-called Unsupervised Learning, a major aspect of modern Machine Learning. The distinctive aspects of the book are both to explore ways to spatialize classic clustering methods through linked maps and graphs, as well as the explicit introduction of spatial contiguity constraints into clustering algorithms. Leveraging a large number of real-world empirical illustrations, readers will gain an understanding of the main concepts and techniques and their relative advantages and disadvantages. The book also constitutes the definitive user’s guide for these methods as implemented in the GeoDa open source software for spatial analysis. It is organized into three major parts, dealing with dimension reduction (principal components, multidimensional scaling, stochastic network embedding), classic clustering methods (hierarchical clustering, k-means, k-medians, k-medoids and spectral clustering), and spatially constrained clustering methods (both hierarchical and partitioning). It closes with an assessment of spatial and non-spatial cluster properties.

One of the most influential data visualization books—updated with new techniques, technologies, and examples. Visualize This demonstrates how to explain data visually, so that you can present and communicate information in a way that is appealing and easy to understand. Today, there is a continuous flow of data available to answer almost any question. Thoughtful charts, maps, and analysis can help us make sense of this data. But the data does not speak for itself. As leading data expert Nathan Yau explains in this book, graphics provide little value unless they are built upon a firm understanding of the data behind them. Visualize This teaches you a data-first approach from a practical point of view. You'll start by exploring what your data has to say, and then you'll design visualizations that are both remarkable and meaningful. With this book, you'll discover what tools are available to you without becoming overwhelmed with options. You'll be exposed to a variety of software and code and jump right into real-world datasets so that you can learn visualization by doing. Details tools that can be used to visualize data graphics for reports, presentations, and stories, for the web or for print, with major updates for the latest R packages, Python libraries, jаvascript libraries, illustration software, and point-and-click applications.

This book is for enterprise and solution architects, systems integrators, and anyone managing enterprise-scale, multi-cloud or hybrid IT landscapes. The book examines usage of Azure Arc for governance and systems management with security as an overarching theme. It is not an implementation manual but provides high-level guidance on best practices and links to detailed guidance. It offers insight into the types of problems that Azure Arc can solve, and will help you determine whether it is the right choice for your organization. Azure Arc is designed to provide a consolidated view of assets such as databases and Kubernetes installations across major cloud providers, edge locations, and customer-owned datacenters. It facilitates deployment of new infrastructure, patching and upgrades, monitoring, policy, and security controls for assets living on-premises or in competitor clouds as if they were native to Azure. While competitive products exist, at this writing none have the flexibility and reach of Arc to effectively manage very large hybrid estates. PostgreSQL, like other technologies covered in this book, owes its existence to Berkeley being a provenience of new computing technologies fostering solutions to some of the biggest data problems in enterprise computing while adhering to an open source model that let the best minds of the IT community test and enhance things like PostgreSQL and Spark. For enterprise and solution architects, systems integrators, and anyone else looking to solve enterprise-scale administration problems across a multi-cloud or hybrid architecture.
