DevOps for Developers describes how to streamline the software delivery process and improve the cycle time (that is the time from inception to delivery). It will enable you to deliver software faster, in better quality and more aligned with individual requirements and basic conditions. And above all, work that is aligned with the “DevOps” approach makes even more fun!

Foundations of GTK+ Development is aimed at C programmers and presents numerous real-life examples that you can immediately put to use in your projects. Some familiarity with C programming is assumed, as the book delves into new topics from the beginning. Topics like object inheritance are covered early on to allow for complete understanding of code examples later. And the provided examples are real-life situations that can help you get a head start on your own applications.
DevOps promises to accelerate the release of new software features and improve monitoring of systems in production, but its crucial implications for software architects and architecture are often ignored.
In DevOps: A Software Architect’s Perspective, three leading architects address these issues head-on. The authors review decisions software architects must make in order to achieve DevOps’ goals and clarify how other DevOps participants are likely to impact the architect’s work. They also provide the organizational, technical, and operational context needed to deploy DevOps more efficiently, and review DevOps’ impact on each development phase. The authors address cross-cutting concerns that link multiple functions, offering practical insights into compliance, performance, reliability, repeatability, and security.
This guide demonstrates the authors’ ideas in action with three real-world case studies: datacenter replication for business continuity, management of a continuous deployment pipeline, and migration to a microservice architecture.
Comprehensive coverage includes
• Why DevOps can require major changes in both system architecture and IT roles
• How virtualization and the cloud can enable DevOps practices
• Integrating operations and its service lifecycle into DevOps
• Designing new systems to work well with DevOps practices
• Integrating DevOps with agile methods and TDD
• Handling failure detection, upgrade planning, and other key issues
• Managing consistency issues arising from DevOps’ independent deployment models
• Integrating security controls, roles, and audits into DevOps
• Preparing a business plan for DevOps adoption, rollout, and measurement

Many experienced programmers try to bend Python to fit patterns they learned from other languages, and never discover Python features outside of their experience. With this book, those Python programmers will thoroughly learn how to become proficient in Python 3.
This book covers:Python data model: understand how special methods are the key to the consistent behavior of objectsData structures: take full advantage of built-in types, and understand the text vs bytes duality in the Unicode ageFunctions as objects: view Python functions as first-class objects, and understand how this affects popular design patternsObject-oriented idioms: build classes by learning about references, mutability, interfaces, operator overloading, and multiple inheritanceControl flow: leverage context managers, generators, coroutines, and concurrency with the concurrent.futures and asyncio packagesMetaprogramming: understand how properties, attribute descriptors, class decorators, and metaclasses work
