Danger! Danger! The very word puts us on notice. As it is designed to do. Don't touch that. Peril ahead. Proceed with caution. But the threat of danger can also be a trap, holding us back from experiencing many wonders of the world, trying new things, going where no one has gone before. In MAKE Volume 35, we confront danger within the world of making, and how to be smarter about risk. We examine safe practices for makers, and we look at the illusion of danger vs. real danger, how to use common sense, and how to educate yourself to work more safely and productively. We're bringing plenty of fire, lightning bolts, and rocket's red glare, too. Guest contributor and celebrated pyromaniac William Gurstelle, author of the best-selling Backyard Ballistics and Whoosh, Boom, Splat, will show us how to make a rocket out of sugar, a tornado out of fire, and a cannon out of dry ice. And Arc Attack member Craig Newswanger shows us how to build the awesome Six-Pack Tesla Coil, made with a beer-bottle capacitor, that'll throw 15" electrical arcs. Other fun, and 100% safety-approved projects include: How to make a phonograph out of Lego bricks A light-up hoodie from Electroluminescent (EL) wire An impressive "high-gain" home media projection screen using little more than latex house paint and sandblasting glass All this, along with the latest developments in maker tech--hardware, software and tools for 3D printing, Arduino, Raspberry Pi, robotics--and much, much more.

Even as data is turning the world upside down, the next revolution is taking shape: realtime data analysis. Data tools like Hadoop are batch-oriented; they're good at taking a set of data, analyzing it, and giving you the result later. But these tools are not particularly good at handling streaming data: data that is constantly arriving, and results that are changing as fast as the data arrives. Storm is a new tool that solves that problem. This book gets you started with it.

REST has changed the way developers build web services and design APIs, but in many ways it's a partial solution. HTTP's design certainly makes REST's elegance possible, but past HTTP practice and expectations, as well as its choice of actions, create some limits. Resource-Oriented Computing (ROC) pushes REST ideas to the next level, both removing many of the crutches developers have used with REST and adding a few key new components for working with the resources at the heart of the REST paradigm. NetKernel, an open source Java application, makes it easy to get started with ROC. This book shows you how.

They do so by saving interlinked descriptions of entities (objects, events, situations, or abstract concepts) while encoding the semantics underlying the terminology. How do you create a knowledge graph? And how do you move it from theory into practice? Using hands-on examples, this practical book shows data scientists and data practitioners how to build their own custom knowledge graphs. Authors Jesus Barrasa and Jim Webber from Neo4j illustrate patterns commonly used for building knowledge graphs that solve many of today's pressing problems. You'll quickly discover how these graphs become exponentially more useful as you add more data. Learn the organizing principles necessary to build a knowledge graph Explore how graph databases serve as a foundation for knowledge graphs Understand how to import structured and unstructured data into your graph Follow examples to build integration-and-search knowledge graphs Understand what pattern detection knowledge graphs help you accomplish Explore dependency knowledge graphs through examples Use examples of natural language knowledge graphs and chatbots

Decentralized finance (DeFi) is a rapidly growing field in fintech, having grown from $700 million to $100 billion over the past three years alone. But the lack of reliable information makes this area both risky and murky. In this practical book, experienced securities attorney Alexandra Damsker explains DeFi's role in both blockchain and finance.

Modern systems contain multi-core CPUs and GPUs that have the potential for parallel computing. But many scientific Python tools were not designed to leverage this parallelism. With this short but thorough resource, data scientists and Python programmers will learn how the Dask open source library for parallel computing provides APIs that make it easy to parallelize PyData libraries including NumPy, pandas, and scikit-learn. Authors Holden Karau and Mika Kimmins show you how to use Dask computations in local systems and then scale to the cloud for heavier workloads. This practical book explains why Dask is popular among industry experts and academics and is used by organizations that include Walmart, Capital One, Harvard Medical School, and NASA. With this book, you'll learn: What Dask is, where you can use it, and how it compares with other tools How to use Dask for batch data parallel processing Key distributed system concepts for working with Dask Methods for using Dask with higher-level APIs and building blocks How to work with integrated libraries such as scikit-learn, pandas, and PyTorch How to use Dask with GPUs

As an aspiring data scientist, you appreciate why organizations rely on data for important decisions—whether it's for companies designing websites, cities deciding how to improve services, or scientists discovering how to stop the spread of disease. And you want the skills required to distill a messy pile of data into actionable insights. We call this the data science lifecycle: the process of collecting, wrangling, analyzing, and drawing conclusions from data. Learning Data Science is the first book to cover foundational skills in both programming and statistics that encompass this entire lifecycle. It's aimed at those who wish to become data scientists or who already work with data scientists, and at data analysts who wish to cross the "technical/nontechnical" divide. If you have a basic knowledge of Python programming, you'll learn how to work with data using industry-standard tools like pandas. Refine a question of interest to one that can be studied with data Pursue data collection that may involve text processing, web scraping, etc. Glean valuable insights about data through data cleaning, exploration, and visualization Learn how to use modeling to describe the data Generalize findings beyond the data
