The 50th Signal Battalion was activated July 1, 1940, at Fort Sheridan, Illinois, not long before the United States was drawn into World War II. In September of 1941, a portion of the Battalion was sent to Iceland, followed by the rest in January of 1942 in order to build a communications infrastructure for Iceland Base Command on the island. Upon completion of that assignment, the Battalion was sent to England to prepare for the invasion of continental Europe. On D-Day, June 6, 1944, the Battalion landed on Utah Beach in support of VII Corp and its assigned units, which continued until the end of the war in Europe. Much of the information and many of the photographs contained in this book came from meeting or conversing over the phone with World War II veterans of the 50th Signal Battalion or the surviving members of their families.

The command-line interface is making a comeback. That's because developers know that all the best features of your operating system are hidden behind a user interface designed to help average people use the computer. But you're not the average user, and the CLI is the most efficient way to get work done fast. Turn tedious chores into quick tasks: read and write files, manage complex directory hierarchies, perform network diagnostics, download files, work with APIs, and combine individual programs to create your own workflows. Put down that mouse, open the CLI, and take control of your software development environment. No matter what language or platform you're using, you can use the CLI to create projects, run servers, and manage files. You can even create new tools that fit right in with grep, sed, awk, and xargs. You'll work with the Bash shell and the most common command-line utilities available on macOS, Windows 10, and many flavors of Linux. Create files without opening a text editor. Manage complex directory strutures and move around your entire file system without touching the mouse. Diagnose network issues and interact with APIs. Chain several commands together to transform data, and create your own scripts to automate repetitive tasks. Make things even faster by customizing your environment, creating shortcuts, and integrating other tools into your environment. Hands-on activities and exercises will cement your newfound knowledge and give you the confidence to use the CLI to its fullest potential. And if you're worried you'll wreck your system, this book walks you through creating an Ubuntu virtual machine so you can practice worry-free. Dive into the CLI and join the thousands of other devs who use it every day. What You Need: You'll need macOS, Windows 10, or a Linux distribution like Ubuntu, Fedora, CentOS, or Debian using the Bash shell.

Linus is today's dominant Internet server platform. System administrators and Web developers need deep Linux fluency, including expert knowledge of shells and the command line. This guide will help you achieve that level of Linus mastery.

In today's Web 2.0 world, JavaScript and Dynamic HTML are at the center of the hot new approach to designing highly interactive pages on the client side. With this environment in mind, the new edition of this book offers bite-sized solutions to very specific scripting problems that web developers commonly face. Each recipe includes a focused piece of code that you can insert right into your application. Why is JavaScript & DHTML Cookbook so popular? After reading thousands of forum threads over the years, author and scripting pioneer Danny Goodman has compiled a list of problems that frequently vex scripters of various experience levels. For every problem he addresses, Goodman not only offers code, but a discussion of how and why the solution works. Recipes range from simple tasks, such as manipulating strings and validating dates in JavaScript, to entire libraries that demonstrate complex tasks, such as cross-browser positioning of HTML elements, sorting tables, and implementing Ajax features on the client. Ideal for novices as well as experienced scripters, this book contains more than 150 recipes for: Working with interactive forms and style sheets Presenting user-friendly page navigation Creating dynamic content via Document Object Model scripting Producing visual effects for stationary content Positioning HTML elements Working with XML data in the browser Recipes in this Cookbook are compatible with the latest W3C standards and browsers, including Internet Explorer 7, Firefox 2, Safari, and Opera 9. Several new recipes provide client-side Ajax solutions, and many recipes from the previous edition have been revised to help you build extensible user interfaces for Web 2.0 applications. If you want to write your own scripts and understand how they work, rather than rely on a commercial web development framework, the JavaScript & DHTML Cookbook is a must.
