Steve Yegge on JavaScript, Rails on Rhino and other things

Back in June I blogged about Steve Yegge’s port of Ruby on Rails to Rhino (the JavaScript engine for the JVM) and his claim that JavaScript was the Next Big Language (NBL). In related news, Dion Almaer has just posted a new video interview (in the Google Code Blog series) of Steve Yegge himself talking about the Ruby on Rhino project, server-side and client side JavaScript. Its always nice to be able to put faces and voices to the names of people who have interesting ideas, and whose Blogs I am following. It’ll also be interesting to see what comes out of this project which Steve is pursuing at Google.

More Prevarication

While visiting InfoQ to read the article on Project Zero that prompted my last blog entry, I noticed that there was a video on Fortress (the new scientific programming language for the Java Virtual Machine that I first blogged about some time ago). In the video, recorded at the JAOO 2006 Conference, Guy Steele’s keynote The Soul of a New Programming Language gives a nice overview to the language and its philosophy. As a former MATLAB power user and ex-Fortran programmer, I find the Fortress language, particularly its use of mathematical notation, very intriguing and worthy of further investigation.

Why prevarication? Because I’m supposed to be marking exams!

Better Web Application Framework: Followup

While going through my feed-reader today, I came across another potential framework, which I can add to the list mentioned earlier. This is Project Zero, an incubator project being developed by IBM. It uses the Java platform and the scripting languages Groovy and/or PHP and seems to be directly targetted at RESTful services development but with support for traditional web applications, AJAX and mashups. I guess that I am going to have to I develop a data model and evaluate the choices that I have before I get even more confused!

Better Web Application Framework

For a web application that I am developing as part of a research project I have decided on using [Python]( for the business logic. The reasons being that the application will use fixed-point binary arithmetic, units, and data output as line-graphs. Python seems to have the libraries that I’ll need for this and is better suited for rapid development than Java.

Part of the requirements that I have been researching this last week have been concerned with the identification of a suitable web application framework for Python. I started out this week assuming that this would be [Django]( and even bought the [book](! However, because this is research, I have the luxury of time so I’ve done some additional research and decided that the alternative frameworks [TurboGears]( and [Pylons]( were also worth a look. Searching Google for getting started screencasts and videos I discovered a [wonderful video]( of a web application framework comparison presentation by Sean Kelly. In this presentation, Sean uses J2EE (Servlets and JSPs), Rails, DJango, TurboGears, Zope/Plone and even Enterprise Java Beans (JBoss) to develop a simple time-tracker application and reports his experiences. Rails, Django and TurboGears come out (roughly in that order), but the big surprise is that [Zope]( comes out top! So, maybe I need to rethink!

I’ve embedded the video here as it’s not only a useful and timely comparison of web application frameworks, it’s also an example of just how useful and inspirational a simple presentation can be!

New Blackboard Tools

Some new features (blogs, wikis, social bookmarking, podcasting) were added to my institution’s Blackboard in the last upgrade. It’s very early days but I managed to try some of these out and blog about my first impressions. Here’s my [blog entry]( It’s hosted on Blackboard so I’m not sure if it will be publicly visible. My apologies if it isn’t! Some of my views are probably influenced by [this Slideshare presentation]( posted by Alan Cann (of Leicester University) which compares *Virtual Learning Environments* (VLEs) and *Personalised Learning Environments* (PLEs).

Winter Trees in Singleton Park

Today my wife and I took a walk in Singleton Park and the botanical gardens and I snapped one or two interesting views with my new camera. I love the dramatic silhouettes that large deciduous trees make in the winter!
