Classical Object-Oriented Programming with ECMAScript
ECMAScript (more popularly known by the name "JavaScript") is the language of the web. In the decades past, it has been used to augment web pages with trivial features and obnoxious gimmicks. Today, the language is used to write full-featured web applications that rival modern desktop software in nearly every regard and has even expanded to create desktop and server software. With increased usage, there is a desire to apply more familiar development paradigms while continuing to take advantage of the language's incredibly flexible functional and prototypal models. Of all of the modern paradigms, one of the most influential and widely adopted is the Classical Object-Oriented paradigm, as represented in languages such as Java, C++, Python, Perl, PHP and others. ECMAScript, as an object-oriented language, contains many features familiar to Classical OO developers. However, certain features remain elusive. This paper will detail the development of a classical object-oriented framework f ...

Cloud Without Compromise
Many companies claim to have "gone to the cloud," yet returns from their efforts are meager or worse. Why? Because they've defined cloud as a destination, not a capability. Using cloud as a single-vendor, one-stop destination is fiction; in practice, today's organizations use a mosaic of capabilities across several vendors. Your cloud strategy needs to follow a hybrid multicloud model, one that delivers cloud's value at destinations you choose. This practical guide provides business leaders and C-level executives with guidance and insights across a wide range of cloud-related topics, such as distributed cloud, microservices, and other open source solutions for strengthening operations. You'll apply in-the-field best practices and lessons learned as you define your hybrid cloud strategy and drive your company's transformation strategy. Learn cloud fundamentals and patterns, including basic concepts and history; Get a framework for cloud acumen phases to value-plot your cloud futur ...

Learning ZeroMQ
Even connecting a few programs across a few sockets is plain nasty when you start to handle real life situations. Trillions? The cost would be unimaginable. Connecting computers is so difficult that software and services to do this is a multi-billion dollar business. So today we're still connecting applications using raw UDP and TCP, proprietary protocols, HTTP, Websockets. It remains painful, slow, hard to scale, and essentially centralized. To fix the world, we needed to do two things. One, to solve the general problem of "how to connect any code to any code, anywhere". Two, to wrap that up in the simplest possible building blocks that people could understand and use easily. It sounds ridiculously simple. And maybe it is. That's kind of the whole point. If you are a programmer and you aim to build large systems, in any language, then Code Connected is essential reading. Code Connected Volume 1 takes you through learning ZeroMQ, step-by-step, with over 80 examples. You will learn t ...
