The tools we use play a critical role in how effective we are. In today’s ever-changing world of technology, we tend to focus on the latest and greatest solutions and overlook the simple tools that are available. Constant improvement of tools is an important aspect of the DevOps movement, but improvement doesn’t always warrant replacement.The tools presented in 5 Unsung Tools of DevOps provide insight into or control over a DevOps environment--and they require minimal installation ...

Five or six years ago, analysts working with big datasets made queries and got the results back overnight. The data world was revolutionized a few years ago when Hadoop and other tools made it possible to getthe results from queries in minutes. But the revolution continues. Analysts now demand sub-second, near real-time query results. Fortunately, we have the tools to deliver them. This report examines tools and technologies that are driving real-time big data analytics.

The goal of the book is introduction into programming, mathematics, sciences for elementary school students. The material is written for student self-study (8-11 y.o.) who have basic skills of operating a computer. Children have to be able to use «a mouse», start using labels, etc., as well as count to 480, multiply and divide. More complex mathematical notions (negative numbers, decimal fractions, coordinate axis, degrees) will be explained on the pages of the book. Scratch is a ...

Many features inspired by popular JavaScript libraries are now available as native JavaScript APIs in today’s powerful browsers. While that may seem convenient given all of the JavaScript you need to write, relying on these APIs will only make code maintenance more difficult in the long run.In this report, Nicholas Zakas—consultant and former front-end tech leader at Yahoo!—provides a case study to show how different browsers can develop native APIs for the same specification and s...

Excel macros. Everybody wants to learn them. You're not a programmer though. How is a non technical user going to learn how to program? You do want to use macros to make your work easier but are you really going to sit down with a huge programming textbook and work your way through every. single. boring. page? Like most people, you'll start with great enthusiasm and vigor but after a few chapters, the novelty wears off. It gets boring.I'm going to try and change that and make learn...

Big data has more disruptive potential than any information technology developed in the past 40 years. As author Jeffrey Needham points out in this revealing book, big data can provide unprecedented visibility into the operational efficiency of enterprises and agencies.Disruptive Possibilities provides an historically-informed overview through a wide range of topics, from the evolution of commodity supercomputing and the simplicity of big data technology, to the ways conve...

HTML5: Everyone’s using it, nobody knows what it is. I realize that sounds more like a line out of an existential movie — maybe Waiting for Godot or a screenplay by Sartre — than a statement about HTML5. But it’s really the truth: most of the people using HTML5 are treating it as HTML4+, or even worse, HTML4 (and some stuff they don’t use). The result? A real delay in the paradigm shift that HTML5 is almost certain to bring. It’s certainly not time to look away, because by the time you loo...

"Data is here, it's growing, and it's powerful." Author Cathy O'Neil argues that the right approach to data is skeptical, not cynical––it understands that, while powerful, data science tools often fail. Data is nuanced, and "a really excellent skeptic puts the term 'science' into 'data science.'" The big data revolution shouldn't be dismissed as hype, but current data science tools and models shouldn't be hailed as the end-all-be-all, either.

A book providing in depth details about the components required to build a gaming computer and directions on how to assemble the parts.

Pi is the controlling constant for circles, globes, orbits, the inverse square power distribution and many of the other fundamental aspects of our universe. This ebook is an effort to put forward the idea that a better understanding of pi is required. The entire knowledge base of our understanding of science could be greatly changed with additional efforts in the study of pi.
