A Utility Tag-Cloud App on Google App Engine

Filed under: Uncategorized — Tags: , , , — roshandawrani @ 6:14 pm

Here is another utility application I have put on Google App Engine – http://mytagclouds.appspot.com/. I wanted to check out how persistence and security works in an application developed for App Engine. Another thing I wanted to check out was how tag clouds are implemented.

This utility allows you to enter items, categorize them and then label them with tags you want to remember those items with. For example, if you want to maintain information about the movies you know, the books you have read, you can create categories called Movies, Books, and then start adding information under books and movies of your interest and easily navigate through the popular ones using the tag clouds that get built up.

Here is the accompanying article I wrote on DZone discussing its technical details.

Groovy AST Browser – Web Based

Filed under: Uncategorized — Tags: , , , — roshandawrani @ 6:13 pm

This was something I wanted to do for some time now. First thing I didn’t like about the existing AST Browser implementation in groovy was that the compilation bits were all intermixed with the Swing tree view implementation bits. Secondly I wanted this tool to be available on web, complementing the Groovy Web Console.
So, I took the opportunity to brush-up some Javascript/CSS/Ajax stuff, separated out in Groovy AST Browser, the compilation bits from the view bits so that it could also present the data in plain text nodes that could then be rendered in non-Swing views.

So, here is the web-based version of AST Browser – deployed on Google App Engine environment – http://groovyastbrowser.appspot.com/

Accompanying this work, here is an article published on DZone: http://groovy.dzone.com/articles/groovy-ast-browser-web-now

Some time back when I started looking into how Groovy++ was implemented, I had written the following 2 articles on DZone about it:
