Mastering Large Datasets with Python
Modern data science solutions need to be clean, easy to read, and scalable. In Mastering Large Datasets with Python, author J.T. Wolohan teaches you how to take a small project and scale it up using a functionally influenced approach to Python coding. You'll explore methods and built-in Python tools that lend themselves to clarity and scalability, like the high-performing parallelism method, as well as distributed technologies that allow for high data throughput. The abundant hands-on exercises in this practical tutorial will lock in these essential skills for any large-scale data science project. Programming techniques that work well on laptop-sized data can slow to a crawl - or fail altogether - when applied to massive files or distributed datasets. By mastering the powerful map and reduce paradigm, along with the Python-based tools that support it, you can write data-centric applications that scale efficiently without requiring codebase rewrites as your requirements change. Ma ...

Deep Reinforcement Learning in Action
Humans learn best from feedback - we are encouraged to take actions that lead to positive results while deterred by decisions with negative consequences. This reinforcement process can be applied to computer programs allowing them to solve more complex problems that classical programming cannot. Deep Reinforcement Learning in Action teaches you the fundamental concepts and terminology of deep reinforcement learning, along with the practical skills and techniques you'll need to implement it into your own projects. Deep reinforcement learning AI systems rapidly adapt to new environments, a vast improvement over standard neural networks. A DRL agent learns like people do, taking in raw data such as sensor input and refining its responses and predictions through trial and error. Deep Reinforcement Learning in Action teaches you how to program AI agents that adapt and improve based on direct feedback from their environment. In this example-rich tutorial, you'll master foundational and ...

RavenDB in Action
The data you encounter in the real world is usually easier to think of as objects or documents than as the tables and rows required by a standard RDBMS. RavenDB, a modern document-oriented database written in .NET, requires no schema to be declared and enables developers to work with data more naturally. RavenDB applications are high-performance, low-latency, and easy to scale and maintain. RavenDB in Action introduces RavenDB and the document database model. After explaining the basics and offering a quick-and-dirty sample application, this end-to-end guide dives into core RavenDB techniques. You'll find thoroughly-documented examples on extending RavenDB, deployment stories, and tips to ensure production readiness, along with coverage of advanced topics like full-text search.

Hacking Secret Ciphers with Python
There are many books that teach beginners how to write secret messages using ciphers. There are a couple books that teach beginners how to hack ciphers. As far as I can tell, there are no books to teach beginners how to write programs to hack ciphers. This book fills that gap. This book is for complete beginners who do not know anything about encryption, hacking, or cryptography. The ciphers in this book (except for the RSA cipher in the last chapter) are all centuries old, and modern computers now have the computational power to hack their encrypted messages. No modern organization or individuals use these ciphers anymore. As such, there's no reasonable context in which you could get into legal trouble for the information in this book. ...

The JavaScript Way
Love it or hate it, JavaScript is avidly eating the world of software development. From web sites and apps to servers, smartphones and connected objects, JavaScript is everywhere. It has evolved from a niche scripting tool crafted in a few days into a modern, multi-purpose language sitting on top of a rich ecosystem and a vibrant developer community. Some even consider JavaScript to be the most important technology in software development nowadays. However, learning JavaScript properly is not that easy. Many resources are outdated and teach obsolete practices. Many others cover advanced topics that are of little interest to beginners and "switchers" coming from other languages and platforms. This book aims to be a useful companion for anyone wishing to (re)discover the many facets of JavaScript. ...

Startups in Action
The growing pains of a startup's initial year in business require a keen awareness of uncertainties and a willingness to adapt in order to survive. Today's new founders greatly benefit from taking a behind-the-scenes look at successful companies such as Etsy, HotelTonight, Fiverr, and more in regards to how they overcame the challenges of their first year. Startups in Action is your curated source for critical insights and inspiration from those who have been there before. This book documents the month-to-month journeys of these companies in their first year, zeroing in on key decisions that helped them recover from missteps, and adapt to complications, to eventually grow and succeed. Were the founders full-time from the beginning? How long did it take them to build a working prototype? How many end-users did they have in the first year? The answers to these questions are of interest to those who are just starting out and want to learn by example. Collected from interviews with the ...
