AJAX in Ruby on Rails with Prototype, Script.aculo.us

Michael Benedict's Blog This tutorial deals with AJAX implementation in Ruby on Rails 2. While I was learning RoR, I had lot of issues of properly having AJAX implementation in my projects. This tutorial is for those people out there. In this tutorial, I`ll just show some very simple Script.aculo.us Animation Implementations in RoR.   View Demo Introduction First off, if you followed my RoR tutorials, you should know that RoR has AJAX support built in to it. It uses the Prototype Javascript Library along with Scriptaculous. Step 1 - Create new RoR Application First create a new RoR application. Edit the database.yml file as well. Step 2 - Create a Controller After creating the new application, we need to create a controller. lets call the controller ajaxfunctions. I hope you guys know how to create a controller. ruby script/generate controller ajaxfunctions index T... (more)

Why Do 'Cool Kids' Choose Ruby or PHP to Build Websites Instead of Java?

Coach Wei's Blog Here is a question that I have been pondering on and off for quite a while: Why do "cool kids" choose Ruby or PHP to build websites instead of Java? I have to admit that I do not have an answer. Why do I even care? Because I am a Java developer. Like many Java developers, I get along with Java well. Not only the language itself, but the development environments (Eclipse for example), step-by-step debugging helper, wide availability of libraries and code snippets, and the readily accessible information on almost any technical question I may have on Java via Google. Last but not least, I go to JavaOne and see 10,000 people that talk and walk just like me. The other reason that I ponder this question is that  the power of Java is a perfect fit for the areas where websites may need more than markups or scripting, such as middleware logic. PHP and Ruby etc ... (more)

Open Source Selenium Web Application Testing System

Selenium is a free Web Application Testing System. It gained lots of popularity since it is available. It’s integration to FireFox – which allows instant record/replay as well as the scripting option - makes it a great tool for functional web testing. BrowserMob on the other side leverages Selenium by providing an automated load-testing environment for Selenium scripts all configurable online via a Web Dashboard. Tagging Web Requests In my recent blog post – Get more out of functional web testing: How to correlate test reports with server side log information? – I discussed the problem that testing results are usually not linked to the log and diagnostics information captured by the application under test. The blog entry offered a way to link the two sides using HTTP Tagging via an HTTP Proxy. Tagging individual Web Requests allows linking each individual request ... (more)

Continuous Integration in Cloud Computing

Download CI Whitepaper Here! Continuous Integration topic launched today on Ulitzer. Continuous integration (http://ci.ulitzer.com) describes a set of software engineering practices that speed up the delivery of software by decreasing integration times. Hudson is an open source "continuous integration" (CI) server initially developed at Sun. This whitepaper describes the capabilities of Hudson, compares Hudson's key features to those of competitive offerings, and summarizes why Hudson has quickly become the industry's most widely adopted open source CI server.

Can Ruby Live Without Rails?

I do not know, use, or have an opinion on the Ruby language yet. But since this language climbed up to the 13th place in the Tiobe index, it deserves to be taken seriously. Bruce Tate is a well know proponent of Ruby. While some people are quick to blame any Java developer who is looking into other  languages,in my opinion it's an attitude of  weak people. If we want Java keep evolving, we need to look around.  I’ve asked Bruce several questions  about this programming language, and this is our blitz-interview. Why this 13-year old language was not known in the programming community until the Ruby on Rails came about? I looked into this extensively for my Beyond Java book. Three important points in time are 1) The emergence of a language. This does not always coincide with the emergence of the catalyst. 2) The emergence of the catalyst. With Oak/Java, you could argue th... (more)

Ruby on Rails One-Day Seminar: Introducing Ruby on Rails – the Pain-Killer for Web Developers

According to its founding light David Heinemeier Hansson (pictured), Ruby on Rails (RoR) is about "taking the pain away and making you happy." Hansson, who was a speaker at SYS-CON Events' inaugural "Real-World AJAX" One-Day Seminar earlier this year, says he knowingly advises people, before they try Rails, to cut their teeth in web-development on the mainstream offerings first. "Once you've tried developing a substantial application in Java or PHP or C# or whatever," he says, "the difference in Rails will be readily apparent. You gotta feel the hurt before you can appreciate the cure." Those attending SYS-CON Events' "Real-World Ruby on Rails" One-Day Seminar, on October 3, 2006 - many of whom by definition have already felt the hurt - can experience the happiness first-hand, when top Ruby on Rails practitioners share their insights, expertise, and code. The Semina... (more)
