Lambda enables users to develop code that executes in response to events - API calls, file uploads, schedules, etc - and upload it without worrying about managing traditional server metrics such as disk space, memory, or CPU usage. With its "per execution" cost model, Lambda can enable organizations to save hundreds or thousands of dollars on computing costs. With in-depth walkthroughs, large screenshots, and complete code samples, the reader is guided through the step-by-step process of creating new functions, responding to infrastructure events, developing API backends, executing code at specified intervals, and much more.

    Following a cookbook-style Problem/Solution/Discussion format, this practical handbook builds on the foundational concepts of the Go language and introduces specific strategies you can use in your day-to-day applications. You'll learn techniques for building web services, using Go in the cloud, testing and debugging, routing, network applications, and much more.

     Lacey Luzzi’s rollercoaster of a life has been filled with the highest of highs and the lowest of lows. She just never expected the lows to be so… sparkly. After falling on her face during an attempt to follow in her recently-deceased mother’s stripper-boots, Lacey realizes she’s not cut out for life on stage. She sets out on a year-long investigation to find her true family, never expecting she’ll find it with a capital “F.” With a rumbling stomach, a need for money (check engine lights don’t fix themselves!), and a conscience that operates at 78% on a good day, Lacey is sucked into a whirlwind of Family secrets, hard-as-cement cookies, and mysterious, sexy men who unfortunately shoot guns, sometimes aimed at her face. The long-lost-granddaughter of Carlos Luzzi, the Godfather of the Italian Mafia, Lacey accepts her first assignment for the mob: finding fifteen million dollars of ‘the good stuff.’ Even after she enlists the help of her mouthy best-friend and her cousin, a technical genius and social disaster, she finds that going toe-to-toe with the rival Russian mob is more dangerous than expected. No one chooses their Family, but Lacey Luzzi will be lucky if she can survive hers. ** ** Lacey Luzzi: Sprinkled, is a full-length, laugh-out-loud, humorous cozy mystery with a strong female protagonist in the spirit of Janet Evanovich’s Stephanie Plum, albeit one working for the wrong side of the law… Note: Rated a strong PG-13 for sarcasm and mild language. No graphic gore or sex.

    With no prior knowledge of game development or 3D required, you will learn from scratch, taking each concept at a time working up to a full 3D mini-game. You'll learn scripting with C# or JavaScript and master the Unity development environment with easy-to-follow stepwise tasks. If you're a designer or animator who wishes to take their first steps into game development or prototyping, or if you've simply spent many hours sitting in front of video games, with ideas bubbling away in the back of your mind, Unity and this book should be your starting point. No prior knowledge of game production is required, inviting you to simply bring with you a passion for making great games.

    Mastering this art will not only make you the most desired developer in the market, but it will transform the craziest deadline into "Consider it done, Sir".

    

    The vision behind Clojure is of a radically simple language framework holding together a sophisticated collection of programming features. Learning Clojure involves much more than just learning the mechanics of the language. To really get Clojure you need to understand the ideas underlying this structure of framework and features. You need this book: an accessible introduction to Clojure that focuses on the ideas behind the language as well as the practical details of writing code.

    This practical book shows you how to bundle reusable R functions, sample data, and documentation together by applying author Hadley Wickham’s package development philosophy. In the process, you’ll work with devtools, roxygen, and testthat, a set of R packages that automate common development tasks. Devtools encapsulates best practices that Hadley has learned from years of working with this programming language. Ideal for developers, data scientists, and programmers with various backgrounds, this book starts you with the basics and shows you how to improve your package writing over time. You’ll learn to focus on what you want your package to do, rather than think about package structure. Learn about the most useful components of an R package, including vignettes and unit tests Automate anything you can, taking advantage of the years of development experience embodied in devtools Get tips on good style, such as organizing functions into files Streamline your development process with devtools Learn the best way to submit your package to the Comprehensive R Archive Network (CRAN) Learn from a well-respected member of the R community who created 30 R packages, including ggplot2, dplyr, and tidyr
