 Название: Command Line : A Modern Introduction
Автор: Petr Stribny
Издательство: Independently published
Год: 2023
Язык: английский
Формат: pdf (true), epub
Размер: 10.1 MB
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 de?ned 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 javascript). In addition to achieving a more ?exible 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-de?ned wrapper code. | |
