Scripting: Higher- Level Programming for the 21St Century
. John K. Ousterhout Sun Microsystems Laboratories Scripting: Higher- Cybersquare Level Programming for the 21st Century Increases in computer speed and changes in the application mix are making scripting languages more and more important for the applications of the future. Scripting languages differ from system programming languages in that they are designed for “gluing” applications together. They use typeless approaches to achieve a higher level of programming and more rapid application development than system programming languages. or the past 15 years, a fundamental change has been ated with system programming languages and glued Foccurring in the way people write computer programs. together with scripting languages.

Ixia Tcl Development Guide
Chapter 2: Quick Start 2 Installing the IxOS Tcl Client This chapter provides a quick means of getting started with the Tcl API. An example test is presented and explained. The IxOS Tcl Client provides an interface between an Ixia Tcl client application and Ixia IxOS Tcl functions. It runs on the Unix / Linux host. The Windows version of IxOS Tcl Client is included with the IxOS software package; the Unix/Linux version is supplied as a separate a self-extracting archive (.bin) file. You can download it from Ixia’s website, www.ixiacom.com. There are serveral versions of the IxOS Tcl Client. The correct file to install depends on the set up of the UNIX/Linux machine. Table 2-2 on page 2-1 details the files and their use. Table 2-2. Tcl Client Install Files Install File Purpose IxOS#.## For Linux versions post Redhat 9.

Steinfurt, Germany Michael Johann mjohann@railsexperts.com http://www.railsexperts.com I am interested in new projects where various modern technologies are combined to build great innovative products. My view is from the full stack developer to architecture and engineering aspects. I am also passionate about being a CTO if the company is trusting my technical experience. I've supported the most known industry standards before thy became mainstream. I've founded JavaSPEKTRUM print magazine in 1996 and RailsWayMagazine (print) in 2009 and have been editor in chief for both magazines. In 2008 I wrote a german book about "JRuby on Rails for Java Enterprise Developers). As a regular speaker at conferences in Europe/USA, I always spread the news about new technologies and how they apply to projects. As a person with multiple interests I combine using technical aspects in development with writing and speaking at conferences. I've been an evangelist for Java and Rails.

John Ousterhout of the University of California, Berkeley, designed it. It is a combination of a scripting language and its own interpreter that gets embedded to the application, we develop with it. Tcl was developed initially for Unix. It was then ported to Windows, DOS, OS/2, and Mac OSX. Tcl is much similar to other unix shell languages like Bourne Shell (Sh), the C Shell (csh), the Korn Shell (sh), and Perl. It aims at providing ability for programs to interact with other programs and also for acting as an embeddable interpreter. Even though, the original aim was to enable programs to interact, you can find full-fledged applications written in Tcl/Tk. Features of Tcl The features of Tcl are as follows − ∑ Reduced development time. ∑ Powerful and simple user interface kit with integration of TK. ∑ Write once, run anywhere. It runs on Windows, Mac OS X, and almost on every Unix platform. ∑ Quite easy to get started for experienced programmers; since, the language is so simple that they can learn Tcl in a few hours or days. ∑ You can easily extend existing applications with Tcl. -

Ruby on Rails™ Tutorial: Learn Web Developments with Rails
ptg8286261 www.it-ebooks.info Praise for Michael Hartl’s Books and Videos on Ruby on RailsTM ‘‘My former company (CD Baby) was one of the first to loudly switch to Ruby on ptg8286261 Rails, and then even more loudly switch back to PHP (Google me to read about the drama). This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on RailsTM Tutorial is what I used to switch back to Rails again.’’ —From the Foreword by Derek Sivers (sivers.org) Formerly: Founder, CD Baby Currently: Founder, Thoughts Ltd. ‘‘Michael Hartl’s Rails Tutorial book is the #1 (and only, in my opinion) place to start when it comes to books about learning Rails. It’s an amazing piece of work and, unusually, walks you through building a Rails app from start to finish with testing. If you want to read just one book and feel like a Rails master by the end of it, pick the Ruby on RailsTM Tutorial.’’ —Peter Cooper Editor, Ruby Inside www.it-ebooks.info ‘‘Grounded in the real world.’’ —I Programmer (www.i-programmer.info), by Ian Elliot ‘‘The book gives you the theory and practice, while the videos focus on showing you in person how its done. Highly recommended combo.’’ —Antonio Cangiano, Software Engineer, IBM ‘‘The author is clearly an expert at the Ruby language and the Rails framework, but more than that, he is a working software engineer who introduces best practices throughout the text.’’ —Greg Charles, Senior Software Developer, Fairway Technologies ‘‘Overall, these video tutorials should be a great resource for anyone new to Rails.’’ —Michael Morin, ruby.about.com ‘‘Hands-down, I would recommend this book to anyone wanting to get into Ruby on Rails development.’’ —Michael Crump, Microsoft MVP ptg8286261 www.it-ebooks.info RUBY ON RAILSTM TUTORIAL Second Edition ptg8286261 www.it-ebooks.info Visit informit.com/ruby for a complete list of available products. -
Deploying with Jruby Is the Definitive Text on Getting Jruby Applications up and Running
Early Praise for Deploying JRuby Deploying with JRuby is the definitive text on getting JRuby applications up and running. Joe has pulled together a great collection of deployment knowledge, and the JRuby story is much stronger as a result. ➤ Charles Oliver Nutter JRuby Core team member and coauthor, Using JRuby Deploying with JRuby answers all of the most frequently asked questions regarding real-world use of JRuby that I have seen, including many we were not able to answer in Using JRuby. Whether you’re coming to JRuby from Ruby or Java, Joe fills in all the gaps you’ll need to deploy JRuby with confidence. ➤ Nick Sieger JRuby Core team member and coauthor, Using JRuby This book is an excellent guide to navigating the various JRuby deployment op- tions. Joe is fair in his assessment of these technologies and describes a clear path for getting your Ruby application up and running on the JVM. ➤ Bob McWhirter TorqueBox team lead at Red Hat Essential reading to learn not only how to deploy web applications on JRuby but also why. ➤ David Calavera Creator of Trinidad Deploying with JRuby is a must-read for anyone interested in production JRuby deployments. The book walks through the major deployment strategies by providing easy-to-follow examples that help the reader take full advantage of the JRuby servers while avoiding the common pitfalls of migrating an application to JRuby. ➤ Ben Browning TorqueBox developer at Red Hat Deploying with JRuby is an invaluable resource for anyone planning on using JRuby for web-based development. For those who have never used JRuby, Joe clearly presents its many advantages and few disadvantages in comparison to MRI.
