Book Description
Ten years ago, Halleck "sold out." The fear of poverty drove him to abandon entrepreneurship, and seek shelter in the vast grey cube farms of a "big old dinosaur" technology company. Fear suppressed Halleck's ambition for a decade, and if it weren't for the mass layoff known as Chainsaw Friday, it might have remained that way for the rest of his life. At the first hint that his employer might lay him off at the end of the quarter, Hal immediately started looking for new work, eventually landing a dream job at a tech startup. All he has to do is show up on Chainsaw Friday, get his layoff papers, and chill out until New Job Monday. But against all odds, his current employer doesn't lay him off, and the non-compete agreement he signed long ago prevents him from taking the startup job. Armed with an underused degree in systems theory and his Generation X Survival Skills, Hal has only a few hours to find and defeat the salaried supervillains who blocked his escape from Corporate Hell. But Chainsaw Friday is more than just a mass layoff at a dysfunctional megacorporation; it's Halleck's last chance to reclaim his humanity and commit to a real existence in a world dominated by fakeness and fear.

Book Description
Completely revised and updated, this best-selling introduction to programming in JavaScript focuses on writing real applications. JavaScript lies at the heart of almost every modern web application, from social apps like Twitter to browser-based game frameworks like Phaser and Babylon. Though simple for beginners to pick up and play with, JavaScript is a flexible, complex language that you can use to build full-scale applications. This much anticipated and thoroughly revised third edition of Eloquent JavaScript dives deep into the JavaScript language to show you how to write beautiful, effective code. It has been updated to reflect the current state of Java¬Script and web browsers and includes brand-new material on features like class notation, arrow functions, iterators, async functions, template strings, and block scope. A host of new exercises have also been added to test your skills and keep you on track. As with previous editions, Haverbeke continues to teach through extensive examples and immerses you in code from the start, while exercises and full-chapter projects give you hands-on experience with writing your own programs. You start by learning the basic structure of the JavaScript language as well as control structures, functions, and data structures to help you write basic programs. Then you'll learn about error handling and bug fixing, modularity, and asynchronous programming before moving on to web browsers and how JavaScript is used to program them. As you build projects such as an artificial life simulation, a simple programming language, and a paint program, you'll learn how to: - Understand the essential elements of programming, including syntax, control, and data - Organize and clarify your code with object-oriented and functional programming techniques - Script the browser and make basic web applications - Use the DOM effectively to interact with browsers - Harness Node.js to build servers and utilities Isn't it time you became fluent in the language of the Web? * All source code is available online in an inter¬active sandbox, where you can edit the code, run it, and see its output instantly.

Book Description
Jython is an open source implementation of the high-level, dynamic, object-oriented scripting language Python seamlessly integrated with the Java platform. The predecessor to Jython, JPython, is certified as 100% Pure Java. Jython is freely available for both commercial and noncommercial use and is distributed with source code. Jython is complementary to Java. The Definitive Guide to Jython, written by the official Jython team leads, covers Jython 2.5 (or 2.5.x)—from the basics to more advanced features. This book begins with a brief introduction to the language and then journeys through Jython’s different features and uses. The Definitive Guide to Jython is organized for beginners as well as advanced users of the language. The book provides a general overview of the Jython language itself, but it also includes intermediate and advanced topics regarding database, web, and graphical user interface (GUI) applications; Web services/SOA; and integration, concurrency, and parallelism, to name a few.
