Об экологическом садоводстве Николай Курдюмов, популярный российский автор-дачник, знает не понаслышке. На протяжении уже многих лет он получает экологически чистый урожай по технологии природного земледелия. Новая книга Николая Курдюмова – это переосмысление опыта, которым он делился в предыдущих публикациях. Из неё вы узнаете, как вырастить на своих грядках здоровые и свободные от «химии» овощи, как обезопасить огород от вредителей, улучшить почву естественным путем и помочь саду благополучно пережить засушливое жаркое лето и суровую зиму.

Теплица – не роскошь, а суровая необходимость, причем не только в северных регионах, но и на юге. Вопрос в том, от чего вы будете защищать растения – от холода, осадков или… жары. Да, даже от нее может защитить теплица, нужно только знать, какие материалы и конструкции наиболее эффективны в каждой конкретной задаче, стоящей перед дачником. Самый известный в нашей стране последователь природного земледелия – модного во всем мире направления в сельском хозяйстве – Николай Иванович Курдюмов в своей книге поделится опытом продления сезона в защищенном грунте и защите урожая от болезней, которые лишают дачников, порой, половины того, что должно было оказаться на их столе.

With millions of new users and several new models, the Raspberry Pi ecosystem continues to expand—along with many new questions about the Pi’s capabilities. The third edition of this popular cookbook provides more than 200 hands-on recipes for running this tiny low-cost computer with Linux, programming it with Python, and hooking up sensors, motors, and other hardware, including Arduino boards and the Internet of Things (IoT).

We live in an age where the most difficult human tasks are now automated. Smart and intelligent robots, which will perform different tasks precisely and efficiently, are the requirement of the hour. A combination of Raspberry Pi and Python works perfectly when making these kinds of robots. Learn Robotics Programming starts by introducing you to the basic structure of a robot, along with how to plan, build, and program it. As you make your way through the book, you will gradually progress to adding different outputs and sensors, learning new building skills, and writing code for interesting behaviors with sensors. You'll also be able to update your robot, and set up web, phone, and Wi-Fi connectivity in order to control it. By the end of the book, you will have built a clever robot that can perform basic artificial intelligence (AI) operations.

Apache Hadoop is one of the most popular big data solutions for distributed storage and for processing large chunks of data. With Hadoop 3, Apache promises to provide a high-performance, more fault-tolerant, and highly efficient big data processing platform, with a focus on improved scalability and increased efficiency. With this guide, you'll understand advanced concepts of the Hadoop ecosystem tool. You'll learn how Hadoop works internally, study advanced concepts of different ecosystem tools, discover solutions to real-world use cases, and understand how to secure your cluster. It will then walk you through HDFS, YARN, MapReduce, and Hadoop 3 concepts. You'll be able to address common challenges like using Kafka efficiently, designing low latency, reliable message delivery Kafka systems, and handling high data volumes.

Flutter is a cross-platform mobile application development framework. It uses the Dart programming language, which was created by Google, and aims to make development easier, faster, and more efficient. This book is going to be your guide, from introducing Flutter to successfully developing a cross platform application. In the first few chapters, we will learn what Flutter is and how to get started with it. We will also take a dive into the widgets world, explore the widget catalog, and learn how to navigate through it. In the next few chapters, we will widen our horizon by learning about networking and accessibility with Flutter. We'll learn what Silvers are and how to use them, and we'll also learn how to use constraints and animations. Before we take a look at how to deploy our applications in Flutter, we will use Firebase for cloud messaging and remote configuration. By the end of the book, you will have learned everything you need to know to get started with your journey of cross-platform mobile development with Flutter.
