Supports PHP as target now. There were also a few improvements all over the place. Still no proper for-loop though (boo! hiss!).

Today I was given the task of hooking jQuery up one of our client's sites, which has been developed to take advantage of the VERY cool features of SP1 for the .NET 3.5 framework. So I set about accessing the data. This task would be simply connecting to a folder on the server that has all the images I want (Yes, I know I should have stored these in much more elegant way, but this was a small, quick and dirty tweak).

This weeks programmer puzzle challenge - to draw some ascii art shapes in the shortest possible code... have fun.. :-)

Steve Yegge transcribes his talk at Google I/O on Server-side JavaScript and Rhino. Among other things he discusses VMs, language interoperability, static vs. dynamic typing, Scala... Disclaimer: slightly longer than usual.

In looking at my Google Analytics statistics, I see a lot of visitors searching for PHP shorthand if/else (ternary) information. I've gone through my code library and picked out some examples of ternary operator usage.

haXe is a high-level object-oriented programming language mainly focused on helping programers develop Websites and Web applications.

Microsoft’s Internet Explorer (IE) platform architect Chris Wilson is engaged in an illuminating war of words with Brendan Eich, the creator of JavaScript who is now the chief technology officer at the Mozilla Corporation, home of FireFox. At issue is the future of JavaScript running in the web browser.

Say you want to start playing around with the new ECMAScript 4 syntax, getting a feel for the code and the features that’ll be included (which is what I’ve been doing lately). Here a short screencast that shows you some ways that you can go about doing that.

I’m still earring a colleague of mine saying: “all the human problems are solvable with an Object Oriented approach.” I didn’t argue a long time with her. She maybe never had to think about other kind of problems, problems that require to break that paradigm apart.

In 1974, Daniel P. Friedman published a little book called The Little LISPer. It was only 68 pages, but it did a remarkable thing: It could teach you to think recursively. It used some pretend dialect of LISP (which was written in all caps in those days). The dialect didn't fully conform to any real LISP. But that was ok because it wasn't really about LISP, it was about recursive functions. You didn't need a computer in order to work through the exercises. After reading the book, I was changed. In a good way. There are very few books that deeply change the way that you think. This is one of those books.

Experimental JavaScript notation for object cloning and composition.

In the classical object oriented model, an object encapsulates local state (instance variables) and contains a pointer to the shared procedures. These procedures are the methods, which operate on the encapsulated state, that forms the environment of the object. Each method can declare local variables as well as look up for additional state information from the shared environment based on lexical scoping rules. So we have the object as the combination of the environment and the set of methods that operate on the environment. Class based languages like Java and C++ provide another abstraction - the class, which instantiates objects by initializing the environment and setting up appropriate pointers to the shared procedures.

In an earlier post, I had mentioned how the Rhino scripting engine and externalized business rules in Javascript saved us the day in one of our client engagements. That experience had me thinking about the virtues of polyglot programming, usefulness of embeddable scripting engine in Java 6 and the essence of the JVM as the next ubiquitous computing platform. However, it took me some more time and a couple of more blog readings to realize the power and elegance of Javascript as a language. Indeed all the capabilities of Javascript within the browser are add-ons to the simple virtues that the language imbibes.
