Rzemiosło w czystej formie. Standardy i etyka rzetelnych programistów

Robert C. Martin

Rzemieślnik to osoba, która jest starannie wyszkolona, doskonale zna się na swoim fachu i czuje dumę z własnej pracy. Zawsze zachowuje właściwą dla zawodu godność i profesjonalizm. Społeczeństwo okazuje zaufanie rzemieślnikom, wierząc, że należycie dbają o wysoką jakość i postępują etycznie. Pisanie oprogramowania to też rzemiosło. I programiści, podobnie jak inni rzemieślnicy, również chcą czuć dumę i satysfakcję ze swojej pracy. Problem w tym, że świat zdaje się dziś wymagać od nich przede wszystkim produktywności, a nie wysokiej jakości kodu. W tej książce znajdziesz zasady definiujące rzemiosło, jakim jest wytwarzanie oprogramowania. Zebrano w niej procedury, standardy i normy etyczne, dzięki którym tworzony kod będzie niezawodny i efektywny, a całe oprogramowanie stanie się powodem do dumy. Zawarto tutaj szereg pragmatycznych wskazówek dotyczących procedur programistycznego rzemiosła. Omówiono też standardy, co powinno ułatwić zrozumienie oczekiwań wobec programistów. Ważnym zagadnieniem jest etyczny kontekst zawodu programisty, czyli fundamentalne zobowiązania, które programiści powinni podjąć względem swojego otoczenia i siebie samych. Istotą rzemiosła programistycznego bowiem jest tworzenie kodu, który budzi zaufanie użytkowników i całych społeczności. Najciekawsze zagadnienia: czym jest prawdziwe rzemiosło programistyczne pięć podstaw: programowanie sterowane testami, refaktoryzacja, prostota projektu, programowanie zespołowe i testy akceptacyjne produktywność, jakość i odwaga w zespołach programistów czym w rzeczywistości jest uczciwość i praca zespołowa dziesięć zobowiązań profesjonalnego programisty Szczyć się swoją pracą i utrzymuj wysoki standard!

SAFe(R) for DevOps Practitioners. Implement robust, secure, and scaled Agile solutions with the Continuous Delivery Pipeline

Robert Wen, Harry Koehnemann

Product development and release faces overlapping challenges due to the combined pressure of delivering high-quality products in shorter time-to-market cycles, along with maintaining proper operation and ensuring security in a complex high-tech environment. This calls for new ways of overcoming these challenges from design to development, to release, and beyond. SAFe® for DevOps Practitioners helps you use a DevOps approach with the Scaled Agile Framework and details how value streams help you resolve these challenges using examples and use cases.The book begins by explaining how the CALMR approach makes DevOps effective in resolving product development roadblocks. Next, you’ll learn to apply value stream management to establish a value stream that enables product development flow, measure its effectiveness through appropriate feedback loops, and find ways of improving it. Finally, you’ll get to grips with implementing a continuous delivery pipeline that optimizes the value stream through four phases during release on demand. This book complements the latest SAFe DevOps courses, and you’ll find it useful while studying for the SAFe DevOps Practitioner (SDP) certification.By the end of this DevOps book, you’ll have gained a clear understanding of how to achieve continuous execution and release on demand using DevOps and SAFe.

You'll also learn about the building blocks of the SAP Intelligent RPA solution and creating bots from initial application declaration to workflow design and deployment, along with making bots run in attended and unattended modes.You'll also learn about SAP Process Automation, the new SAP service that is going to replace the SAP Intelligent RPA service soon. Finally, we will discuss the migration path for your SAP Intelligent RPA projects to SAP Process Automation and showcase that the RPA development remains similar in both services.By the end of this RPA book, you’ll be able to create and manage complex bots that are capable of interacting with SAP and non-SAP systems.

Scala Reactive Programming. Build scalable, functional reactive microservices with Akka, Play, and Lagom

Rambabu Posa

Reactive programming is a scalable, fast way to build applications, and one that helps us write code that is concise, clear, and readable. It can be used for many purposes such as GUIs, robotics, music, and others, and is central to many concurrent systems. This book will be your guide to getting started with Reactive programming in Scala.You will begin with the fundamental concepts of Reactive programming and gradually move on to working with asynchronous data streams. You will then start building an application using Akka Actors and extend it using the Play framework. You will also learn about reactive stream specifications, event sourcing techniques, and different methods to integrate Akka Streams into the Play Framework. This book will also take you one step forward by showing you the advantages of the Lagom framework while working with reactive microservices. You will also learn to scale applications using multi-node clusters and test, secure, and deploy your microservices to the cloud.By the end of the book, you will have gained the knowledge to build robust and distributed systems with Scala and Akka.

Secret Recipes of the Python Ninja. Over 70 recipes that uncover powerful programming tactics in Python

Cody Jackson, Steven F. Lott

This book covers the unexplored secrets of Python, delve into its depths, and uncover its mysteries.You’ll unearth secrets related to the implementation of the standard library, by looking at how modules actually work. You’ll understand the implementation of collections, decimals, and fraction modules. If you haven’t used decorators, coroutines, and generator functions much before, as you make your way through the recipes, you’ll learn what you’ve been missing out on. We’ll cover internal special methods in detail, so you understand what they are and how they can be used to improve the engineering decisions you make. Next, you’ll explore the CPython interpreter, which is a treasure trove of secret hacks that not many programmers are aware of.

Security Automation with Ansible 2. Leverage Ansible 2 to automate complex security tasks like application security, network security, and malware analysis

Akash Mahajan, MADHU AKULA

Security automation is one of the most interesting skills to have nowadays. Ansible allows you to write automation procedures once and use them across your entire infrastructure. This book will teach you the best way to use Ansible for seemingly complex tasks by using the various building blocks available and creating solutions that are easy to teach others, store for later, perform version control on, and repeat.We’ll start by covering various popular modules and writing simple playbooks to showcase those modules. You’ll see how this can be applied over a variety of platforms and operating systems, whether they are Windows/Linux bare metal servers or containers on a cloud platform. Once the bare bones automation is in place, you’ll learn how to leverage tools such as Ansible Tower or even Jenkins to create scheduled repeatable processes around security patching, security hardening, compliance reports, monitoring of systems, and so on. Moving on, you’ll delve into useful security automation techniques and approaches, and learn how to extend Ansible for enhanced security. While on the way, we will tackle topics like how to manage secrets, how to manage all the playbooks that we will create and how to enable collaboration using Ansible Galaxy. In the final stretch, we’ll tackle how to extend the modules of Ansible for our use, and do all the previous tasks in a programmatic manner to get even more powerful automation frameworks and rigs.

Selenium WebDriver Quick Start Guide. Write clear, readable, and reliable tests with Selenium WebDriver 3

Pinakin Chaubal

Selenium WebDriver is a platform-independent API for automating the testing of both browser and mobile applications. It is also a core technology in many other browser automation tools, APIs, and frameworks. This book will guide you through the WebDriver APIs that are used in automation tests.Chapter by chapter, we will construct the building blocks of a page object model framework as you learn about the required Java and Selenium methods and terminology.The book starts with an introduction to the same-origin policy, cross-site scripting dangers, and the Document Object Model (DOM). Moving ahead, we'll learn about XPath, which allows us to select items on a page, and how to design a customized XPath. After that, we will be creating singleton patterns and drivers. Then you will learn about synchronization and handling pop-up windows. You will see how to create a factory for browsers and understand command design patterns applicable to this area.At the end of the book, we tie all this together by creating a framework and implementing multi-browser testing with Selenium Grid.
