iOS 15 takes your iPhone to new levels, with solid updates to many of its key applications. Safari, for example, gets an extensive makeover. FaceTime boasts several improvements, including Voice Isolation, which ignores ambient sounds in favour of focusing on the speaker. A new Grid View for voice chats keeps everyone in view instead of shrinking those who haven’t spoken for a while; and if your iPhone is new enough, you can select Portrait Mode to blur the background around you as you chat. There are also improvements to iCIoud, Messages, Spotlight, Weather and more. New features are thin on the ground with iOS 15 - far more attention has been spent on polishing and improving existing apps and capabilities. That’s not to say there’s nothing that’s completely new. The brand new Focus combines a whole series of features designed to help you concentrate on what’s important to you now. You can make custom Focus settings for work, free time and more. Look out too for Live Text, which lets you copy words from images such as photographs and paste it into documents such as notes, emails and more. It’s all in iOS 15!

This book starts with the concepts in RDBMS (Relational Database Management Systems) and SQL (Structured Query Language). The first few chapters cover the definitions and a brief explanation of all the important concepts. They also cover the installation of MariaDB and MySQL on Windows and Raspberry Pi, as well as the setup of various tools used to connect to MySQL and MariaDB server processes. We will also understand how to install sample schemas and how to use basic SQL queries. Then we move on to the SELECT query in detail. The book explores the data retrieval aspect of SQL queries in detail with the WHERE clause and NULL handling in detail. The book also explores the functions available in MySQL. Those are single row and group functions. Then we explore how to combine the data from multiple sources. The technique is known as Joins, and we will learn ANSI style and the old-style syntax for all the types of Joins.

You'll find several books on MySQL basics today, but only one that covers advanced MySQL performance--and nothing in between. That's because explaining MySQL performance without addressing its complexity is difficult. This practical book bridges the gap by teaching developers mid-level MySQL knowledge beyond the fundamentals, but well shy of deep-level internals required by DBAs.
Daniel Nichter shows you how to apply best practices and techniques that directly affect efficient MySQL performance. You'll learn how to focus on query response time, optimize queries and data to increase performance, and monitor and understand the most important MySQL metrics. You'll also discover how not to use MySQL, including situations where this database is clearly the wrong choice.

Tensor is a natural representation for multi-dimensional data, and tensor computation can avoid possible multi-linear data structure loss in classical matrix computation-based data analysis.
This book is intended to provide non-specialists an overall understanding of tensor computation and its applications in data analysis, and benefits researchers, engineers, and students with theoretical, computational, technical and experimental details. It presents a systematic and up-to-date overview of tensor decompositions from the engineer's point of view, and comprehensive coverage of tensor computation based data analysis techniques. In addition, some practical examples in machine learning, signal processing, data mining, computer vision, remote sensing, and biomedical engineering are also presented for easy understanding and implementation.
