ROS Robotics By Example. Bring life to your robot using ROS robotic applications
Carol Fairchild, Dr. Thomas L. Harman
The visionaries who created ROS developed a framework for robotics centered on the commonality of robotic systems and exploited this commonality in ROS to expedite the development of future robotic systems. From the fundamental concepts to advanced practical experience, this book will provide you with an incremental knowledge of the ROS framework, the backbone of the robotics evolution. ROS standardizes many layers of robotics functionality from low-level device drivers to process control to message passing to software package management. This book provides step-by-step examples of mobile, armed, and flying robots, describing the ROS implementation as the basic model for other robots of these types. By controlling these robots, whether in simulation or in reality, you will use ROS to drive, move, and fly robots using ROS control.

Rozwijanie mikrousług w Pythonie. Budowa, testowanie, instalacja i skalowanie Mikrousługi są bardzo ciekawym trendem tworzenia kodu. Pojawił się on kilka lat temu z uwagi na potrzebę przyspieszenia cyklu udostępniania oprogramowania. Nowe produkty i funkcje musiały być oferowane użytkownikom możliwie najszybciej. Wkrótce okazało się, że tworzenie architektury aplikacji składającej się z małych, funkcjonalnych jednostek - właśnie mikrousług - jest bardzo obiecującym sposobem pracy. Pozwala na zwiększenie się elastyczności oraz szybkości wprowadzania innowacji, gdyż programista może zająć się jednym elementem bez zastanawiania się nad całością aplikacji. W świecie, w którym rządzą wydajność i krótki czas dostarczania kodu, jest to duża wartość! Dzięki tej książce dowiesz się, w jaki sposób niewielkie, standardowe elementy kodu mogą złożyć się na kompletną, działającą aplikację. Nauczysz się tworzyć takie mikrousługi, rozwiązywać pojawiające się problemy i nabierzesz nawyku stosowania dobrych praktyk. Szybko zaczniesz pisać aplikacje w Pythonie za pomocą szerokiego wachlarza dostępnych narzędzi, włączając w to Flask czy Tox. Przy okazji nauczysz się zasad programowania zorientowanego na testy. Dowiesz się, jak zabezpieczać komunikację pomiędzy usługami i kodować funkcjonalności zapory aplikacyjnej w języku Lua dla serwera Nginx. Poznasz też możliwości instalowania mikrousług w chmurze AWS z wykorzystaniem kontenerów Docker. W tej książce między innymi: mikrousługi i ich rola w tworzeniu nowoczesnych aplikacji WWW cykl tworzenia kodu pod kątem testów i ciągłej integracji monitorowanie i zabezpieczanie mikrousług tworzenie mikrousług w JavaScript budowa mikrousług niezależnie od operatorów chmurowych i technologii wirtualizacyjnych unikanie problemów wynikających z centralizacji aplikacji Mikrousługi w języku Python: integracja doskonała!

Azure Data Explorer (ADX) enables developers and data scientists to make data-driven business decisions. This book will help you rapidly explore and query your data at scale and secure your ADX clusters.The book begins by introducing you to ADX, its architecture, core features, and benefits. You'll learn how to securely deploy ADX instances and navigate through the ADX Web UI, cover data ingestion, and discover how to query and visualize your data using the powerful Kusto Query Language (KQL). Next, you'll get to grips with KQL operators and functions to efficiently query and explore your data, as well as perform time series analysis and search for anomalies and trends in your data. As you progress through the chapters, you'll explore advanced ADX topics, including deploying your ADX instances using Infrastructure as Code (IaC). The book also shows you how to manage your cluster performance and monthly ADX costs by handling cluster scaling and data retention periods. Finally, you'll understand how to secure your ADX environment by restricting access with best practices for improving your KQL query performance.By the end of this Azure book, you'll be able to securely deploy your own ADX instance, ingest data from multiple sources, rapidly query your data, and produce reports with KQL and Power BI.

Amazon Kinesis is a collection of secure, serverless, durable, and highly available purpose-built data streaming services. This data streaming service provides APIs and client SDKs that enable you to produce and consume data at scale.Scalable Data Streaming with Amazon Kinesis begins with a quick overview of the core concepts of data streams, along with the essentials of the AWS Kinesis landscape. You'll then explore the requirements of the use case shown through the book to help you get started and cover the key pain points encountered in the data stream life cycle. As you advance, you'll get to grips with the architectural components of Kinesis, understand how they are configured to build data pipelines, and delve into the applications that connect to them for consumption and processing. You'll also build a Kinesis data pipeline from scratch and learn how to implement and apply practical solutions. Moving on, you'll learn how to configure Kinesis on a cloud platform. Finally, you’ll learn how other AWS services can be integrated into Kinesis. These services include Redshift, Dynamo Database, AWS S3, Elastic Search, and third-party applications such as Splunk.By the end of this AWS book, you’ll be able to build and deploy your own Kinesis data pipelines with Kinesis Data Streams (KDS), Kinesis Data Firehose (KFH), Kinesis Video Streams (KVS), and Kinesis Data Analytics (KDA).
