Google Summer of Code 20008

Goole Summer of Code - Dojo

Self Introduction

Hi, my name is Tommy Chang(Chang Qi). I'm a graduate student in Graduate University of Chinese Academy of Sciences ,which is the most famous Graduate University in China.I focus on Java and Javascript technology. I've half year intern work experience in Web2.0 team, IBM CDL(Chinese Development Lab) .My manager is IBM's STSM MaoXinsheng. Before worked in IBM, I worked in BEA Tuxedo CCE team, BEA Chinese R&D Center for half year. My resume can provide more information about me.

For this time's Google Summer of Code, I mainly want to work with Dojo fundation and maybe my IBM colleague.

Dojo Coding Test

The Dojo Coding Test is the first challenge for me. I'm not sure if my course is good enough,but I've tried really hard. The final test page is here . You can download the full project here(I only upload the folder contains the js code,build profile and buildDojoDemo.bat. but not the whole project) The final test page :

Contains three dijit: dojodemo.Grid, dojodemo.Filter, dojodemo.dataChart and adapter(dojodemo.testData)for the given data which can not match the Grid and Charting's data structure.
Represent the filtered json data in to the dojox.Grid,
Can filter the data:click the Filter and choose the Filter column,operation,value and click ok will filter the given data.now have > , < , = , RegExp four operations.
Can compare the data and show the filtered data's chart:
For instance, if you want to see the total score in different ages, you should select age as the X-Axis and total as Y-Axis, then it will generate the right chart.
In the above example, the x-Axis is number, and you can also generate the chart with string x-axis : if you want to show the total score with different campus ,you can select campus as the X-Axis and the total as the Y-Axis
Can reset the data.
Create the dojodemo.profile.js and the buildDojoDemo.bat can build and compress the javascript.
Use D.O.H Unit test to make sure the quality of the javascript code.
now the chart can only one line chart.And the page can not work in IE :-( ....

Some suggestion about Dojo coding test:
1.
I think this is a very good way to select candidate student. However I think this test is mainly measure the students skills in using the framework like dojo but I doubt if this test can check the students' js basic knowledge. If the test contain some basic js test, it would be perfect.

2.
I think the dojo code test should release more earlier before the student application time for we have time to do the test and have enough time to prepare the application it self.

Application: Improved Developer Tools

Abstract:

Development tools and debugging tools for JavaScript aren't the best, which makes it harder for Dojo users.This proposal is aim to help dojo developers to visualize the public/subscribe event design and operations. This tool can unsubscribe a topic by cut the line between the topic and the function, highlight the connection when the topic is published etc.
This tool will be applicable for both Firebug and Firebug Lite to extending the working range.To make it work in Firebug Lite,I should extend the Firebug Lite with JavaScript browser and DOM browser.

Detailed Description

Self-Introduction:
I'm a 2nd year student in Graduate University of Chinese Academy of Sciences, I've worked as an intern in Web2.0 team,IBM Chinese Development Lab for half years.Before join IBM, I worked as an intern in Tuxedo CCE team,BEA Chinese R&D Center.My work in the client side is mainly use Dojo0.4 and Dojo1.0 to develop widget/dijit and some applications.From then on,I paid more attention to Dojo and Google summer of code,I'm looking forward to work with you to improve my programming skills and contribute to our community. My resume link is here: http://www.tommyandtina.com/resume-EN
=========================================
Project proposal details:
1.Dojo event connection visualization tool.
Dojo's pub/sub event system is powerful,but we can not see the whole map which function have subscribe a topic, and can not show the connection status.This part is focus on the visualization the relations by topic name and can highlight when one topic is fired.This visualization can also trace the JavaScript code which publish or subscribe a topic.This tool will be applicable for both Firebug and Firebug Lite to extending the working range.
M1. Warm up and build a static event connection visualization tool into firebug lite using dojox.gfx.(2 weeks)
1.A new view to show the pub/sub event connection status.
2.Connected the pub/sub function with a line.
M2. Extension for Firebug Lite for preparation of Dojo Event Visualization.(2 weeks)
1.JavaScript view like the firebug's, and can located to the specific function.
2.DOM view like the firebug's and can trigger it when console a DOM node.
M3. Interaction for the connections (3 weeks)
1.Highlight the connection when publish a topic.
2.Highlight the function when the function unsubscribe a topic.
3.Can view the pub/sub's JavaScript code when click the pub/sub function link.I should develop another tab in Firefox to show loaded javaScript code.
M4. Migrate the visualization tool to the Firebug as a plug-in like the Yslow.(3 weeks)
1.I've only developed a simple Firefox plug-in, so I need do more investigations on it.that's why it may take more time to accomplish.
2.Can fire up firebug's JavaScript view when click the pub/sub function in dojo event view.

==============================================
Why this project?
I've more than half years develop experience in Dojo,and many of us found it is very hard to debug the Dojo, especially in IE and other browser.So I think if we can strengthen both Firebug Lite and Firebug to develop and debug Dojo more easily, that would be great The public and subscribe event system is really a good thing for programmers to loose coupling for different part.However, if we use pub/sub everywhere in the program without well design, we will definitely get lost and can not find how many subscription for the topic.In addition, I will strengthen the Firebug Lite to let the tool available which can make this debug tool more useful for other browsers.
So I think this project is very useful

===========================================
Why me?
1.I'm familiar with dojo and JavaScript:
I've taken part in 3 projects using Dojo when I was worked as intern in IBM Web 2.0 team.I've sufficient knowledge in JavaScript and HTML/CSS/DOM knowledge.

2.I'm a good team worker and a good learner.
I've worked with the global members using Bugzilla svn and mylyn to track bugs,upload code,task management.Because of my good working, I was invited to share my experience in IBM Campus Hire Program website(http://campus.chinahr.com/2008/pages/bluestart/CDL/blueculture_08.asp).

3.I've experiences in JavaScript and Dojo development.

My last job is in ProjectZero's Assembly Tooling team which is use dojo.gfx to develop a flow customized tooling like Yahoo pipes.I've developed one of its component named WebUI which can visual design a form and auto generate the UI Layers code in the server side. And my work has been applied in the project.
And I've learned a lot of knowledge about dojox.gfx and SVG/VML. For the experiences I mentioned above I believe I have sufficient knowledge to accomplish this goal in 3 months.
You can check the projects recently I've done at: http://www.tommyandtina.com/resume-EN#Project

=============================================
The project I most enthusiastic about.
The WebUI project mentioned above is the most enthusiastic project for me. There are many IBMer's help me to make this component more readable and more professional.From then on, I payed more and more attention to Refactoring,Design Pattern and Unit Test,which make my code more grace and readable.And the component I worked have be a part of Simple collaboration in Assemble Flow

=========================================
Do you consider this your full-time job over summer or are there other committments you know about now which could conflict with SoC?

I can work for SoC as a fulltime job in the summer.
