• Have you participated in an open-source project before? If so, please send us URLs to your profile pages for those projects, or some other demonstration of the work that you have done in open-source. If not, why do you want to work on an open-source project this summer?

No, this is my first time.

About your project

• What is the name of your project?

Interactive Javascript Shell

• Describe your project in 10-20 sentences. What are you making? Who are you making it for, and why do they need it? What technologies (programming languages, etc.) will you be using?

The main aim of the project is to create an platform that can be used to run Javascript or code written in any other language to be compiled and run immediately.

I would very much like to extend the idea to make a very flexible application and with some more features. I propose an application that would provide an easy interface to create web based(HTML5/CSS & JS, runnable on any supported browser) interactive tutorials that can be installed on any local (or remote host) server machine to host the created tutorials for learning programming languages.

• What is the timeline for development of your project? The Summer of Code work period is from May 19 - August 22; tell us what you will be working on each week. (As the summer goes on, you and your mentor will adjust your schedule, but it's good to have a plan at the beginning so you have an idea of where you're headed.) Note that you should probably plan to have something "working and 90% done" by the midterm evaluation (27 June); the last steps always take longer than you think, and we will consider cancelling projects which are not mostly working by then.

Till Week 0 : I have been looking into existing interactive web based code compilation platforms. We can use NodeJS’s child_process api compile and execute any language code including JS.

Week 1 - 2 : Complete the basic UI of the web based code editor and the virtual commandline tool. Write the server code using NodeJS that is to be installed on the local server. The web UI will communicate with this server using JS & jQuery.

Week 3 : Add support for creating local repositories/folder and saving codes to files.

Week 4 - 5 : Create the GUI tool for teacher to make step by step tutorials. These would be stored in the server as JSON format so that it can be loaded by XO using the Interactive Shell. (or a REST api service, would make further improvements easy)

Week 6 - 8 : Visual Debugger - Debugging skills are of greater importance than to just write the code. There will always be bugs and errors in a code freshly written. The application must have a visual debugger in the interactive JS Shell. I am thinking of using this tool for this purpose. https://github.com/adobe-research/theseus

Week 9 : Solely for error fixing and finishing up anything left from the last weeks.

Week 10 - 11 : Sanbox the code Security is a very big concern for virtual execution environments. Create a code filtering system for checking code to make sure that the server doesn't crash.

Week 12 : Write a documentation for everything done till now.

Last Weeks : Test the code and fix any left bugs.

• Convince us, in 5-15 sentences, that you will be able to successfully complete your project in the timeline you have described. This is usually where people describe their past experiences, credentials, prior projects, schoolwork, and that sort of thing, but be creative. Link to prior work or other resources as relevant.

I already have started to work on the project to get a taste of the project. I am pretty sure that I will be able to complete each and every task before the deadline that I have proposed.

I have experience of both web development and mobile app design. I have been involved in our college's Spring Fest technical team during my second year and also held the position of web head in Technology Transfer Group, IIT Kharagpur.

I built a php and ajax based content management system for patent application moderation(Patent Portal - http://ttg-sric.iitkgp.ernet.in/Patent_portal_v2/) in my college under Sponsored Research and Industrial Consultancy Department of IIT Kharagpur. In my second year I built an windows phone app for Spring fest.

Currently, I am working on a project where I have developed an android app which takes the mic input (source - a bio-medical device measuring blood flow of a patient) and computes the FFT of the signal and plots them for a real time visualization. Currently I am working on recognizing patterns within the FFT of the signal to detect any abnormality in patients blood flow/heart condition.

You and the community

• If your project is successfully completed, what will its impact be on the Sugar Labs community? Give 3 answers, each 1-3 paragraphs in length. The first one should be yours. The other two should be answers from members of the Sugar Labs community, at least one of whom should be a Sugar Labs GSoC mentor. Provide email contact information for non-GSoC mentors.

My opinion : First of all my answer to why programming is important is that there is a great fun in coding and that's something which will make you keep going to learn more about it. Also it just can't be learned by reading books or attending lectures, you have to try it out. Learning computer is very important to keep up the pace with the outer world. It also help you to understand how these computers, smartphones and those cool gadgets work. To me it is the easiest way to build things.

• What will you do if you get stuck on your project and your mentor isn't around?

The only language I learned by doing a formal course is C. Now I know C++, Java, C#, HTML, JS and have developed for Windows, Android, Web and yes I learned it all by myself. So, if I get stuck somewhere I am sure to find a way out of it. If it is worse than that and my mentor isn't around then I will approach Google Search, IRC, stackoverflow and my friends.

• How do you propose you will be keeping the community informed of your progress and any problems or questions you might have over the course of the project?

The best way to keep everyone informed what I've been doing and how did I do it is to write a blog.
