"In this course, we'll teach you the basics of using Git and explain how it works. To begin with, we'll show you how to install Git and effectively use your computer's terminal or command line to navigate the file system, and create and edit files. Then we'll cover all the commonly used commands in Git that make up the vast majority of any Software Engineer's workflow. Moving on, we'll explain Git's branching workflow, why it's such a useful feature, and how to use it in your projects. Once you've learned all this, we'll discuss some advanced Git workflow techniques that will make you a valued contributor and collaborator on any project. You'll be able to create your own Git repositories, or clone and contribute to existing ones. This will allow you to track the changes to sets of files over time, recover data you might lose, and collaborate with others on projects. You'll have a profound understanding of Git's branching workflow, and how to use it in the best possible way in your projects. By the end, you'll be familiar with using Git and use VCS to handle large projects easily and make well-crafted contributions to your own or others' projects."--Resource description page

"Git has emerged as the leading revision control system for open source projects. Git is a distributed revision control and source code management (SCM) system with an emphasis on speed. Git Essentials LiveLessons teaches the skills necessary to version control with git. The first part of the course begins with the basics of Git and how to use it as an individual programmer. Part 1: Git Fundamentals covers installation and setup, fundamental commands, and how to use remote and branches in git using Github as the online hosting service to lay the foundation for more advanced workflows. After the basics are covered, Part 2: Collaborating with Git shows how to work collaboratively with teams with git. Three common ways of collaboration are covered, including: adding other users to your project repository, forking a copy of repository and submitting changes for review, and finally using the git flow workflow."--Resource description page.

Prevent (or solve) problems with your Apple ID! Version 3.2, updated January 17, 2022 This book covers everything someone needs to know about configuring an Apple ID account, interactions with iCloud-based services, and troubleshooting account access. Your Apple ID is much more than a simple username. It's a key that unlocks a long list of Apple products and services on any of numerous devices. iCloud uses an Apple ID, as does Apple Music; the App Store; the Music, TV, and Books apps; and more. An Apple ID protects your personal information, including email and iOS/iPadOS backups; helps you find a lost iPhone; and can even unlock your Mac. So it goes without saying that if something goes wrong with your Apple ID, you could be in for a world of hurt. Unfortunately, things go wrong with Apple IDs all the time. Fortunately, Glenn Fleishman, a veteran technology journalist and the author of Macworld's "Mac 911" column, is ready to help with expert advice on how to manage your Apple ID--including how to prevent, solve, or work around most common problems! In this book, Glenn answers questions like: What all is my Apple ID used for? How does my iCloud account relate to my Apple ID? What problems can two-factor authentication (2FA) solve, and how do I use it? Are there other mechanisms I can use to ensure that I can recover an Apple ID in the event of a problem? (Spoiler: yes!) What if I have a device that's too old to work with two-factor authentication? What should I do if I have two or more Apple IDs or iCloud accounts? Will I lose access to all my Apple media purchases if I move to another country? Can I share an Apple ID with someone else? What exactly should I do if I think someone is hacking my Apple ID account? How can I recover a forgotten Apple ID password? What steps should I take if Apple locks me out of my account? If I lose access to an email address associated with my Apple ID, what can I do? What Apple ID changes in iOS 15/iPadOS 15 and macOS 12 Monterey do I need to know about? How does "Sign in with Apple" work? How can I use Family Sharing to share data and purchases within my family? What types of subscriptions can I manage with my Apple ID, and how? Which payment methods can I associate with my Apple ID, and how do I manage them? And that's just the beginning. Glenn has packed a remarkable amount of concise problem-solving information into this compact book. Read it before you encounter Apple ID problems to minimize your risk, and if you've already encountered a problem, read it to find the best path to a rapid solution.

This resource introduces the IBM Software Defined Environment (SDE) solution, which helps to optimize the entire computing infrastructure--compute, storage, and network resources--so that it can adapt to the type of work required. In an SDE, workloads are dynamically assigned to IT resources based on application characteristics, best-available resources, and service level policies so that they deliver continuous, dynamic optimization and reconfiguration to address infrastructure issues. Underlying all of this are policy-based compliance checks and updates in a centrally managed environment. SDE can accelerate business success by matching workloads and resources so that you have a responsive, adaptive environment. -- Edited summary from book.

Fundierte Einführung in relationale Datenbanken und die Anfragesprache SQL Datenbanken für die Berufspraxis verstehen, anwenden und entwickeln Mit zwei durchgängigen Beispielen und zahlreichen Übungen Datenbanken haben sich zu einem unverzichtbaren Bestandteil jeglicher Informationssysteme entwickelt, um größere Mengen strukturierter Daten verwalten, wiederauffinden und analysieren zu können. Die Autoren vermitteln fundiert und kompakt die zum Verständnis und auch zur Entwicklung solcher Systeme notwendigen Kenntnisse aus den Bereichen Datenbankentwurf, Datenmodellierung, Datenänderungen und Datenanalysen und stellen die relationale Datenbanksprache SQL ausführlich vor. Alle Konzepte und Sprachelemente erläutern die Autoren anhand von zwei durchgängigen Beispielen. Des Weiteren besprechen die Autoren Themen wie Nutzersichten, Datenschutz, Integritätssicherung, Tuning von Datenbankanwendungen sowie statistische Datenanalysen (Data Warehousing, Data Mining). Sie erläutern auch neuere Entwicklungen wie NoSQL-Datenbanksysteme, spaltenorientierte Speicherungsformen und die Analyse von Big Data. Das Buch richtet sich vor allem an Schüler und Studenten außerhalb des Fachbereichs Informatik, die schnell und dennoch fundiert die Grundlagen zur Entwicklung und zum Einsatz von Datenbanken lernen wollen. Übungsaufgaben am Ende jedes Kapitels machen das Buch ideal für Studium und Selbststudium. Aus dem Inhalt: Was sind Datenbanken?
