== F: Feeling fine ==
* Please describe (in short) your experience with the following tools:
** IRC and mailing lists
**: I am comfortable using the mailing list and IRC. These are my interactions in the mailing list: [http://octave.1599824.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=372104 Posts]
** Mercurial or other source code management systems
**: I am very comfortable using git. I have started learning Mercurial and do understand the basics of generating a patch in Octave.
** Mediawiki or other wiki software
**: I started using Mediawiki when I started writing this application. I am comfortable contributing to wiki pages.
** make, gcc, gdb or other development tools
**: I am very comfortable in using make tool, gcc, and gdb. Furthermore, I am always pumped up in learning new tools if my project demands for it (or even just out of curiosity).
* What will make you actively stay in our community after this GSoC is over?
*: I see lots of places where I can help. I am also interested in the Convolutional Neural Networks (CNNs) package. I would love to work upon that after my GSoC.

== O: Only out of interest ==
* Did you ever hear about Octave before?
*: Yes, I have heard of GNU Octave before. 
** If so, when and where? How far have you been involved already?
**: I started using Octave for my online Machine Learning Course by Andrew Ng in Coursera.
* What was the first question concerning Octave you could not find an answer to rather quickly? 
*: Complete steps to build Octave from source. The reason for that is that there is not much in the Octave docs. 
*: It is overwhelming as there exists more than one wiki explaining similar steps in various ways. 
*: It might be better to update the Octave docs frequently with latest installation instructions. 
*: Here is what the octave docs show now: [https://www.gnu.org/software/octave/doc/v4.0.1/Building-the-Development-Sources.html#Building-the-Development-Sources link]. 
*: Apart from this, the Octave manual has been very helpful with useful examples to understand concepts.

== P: Prerequisites ==
* Please state the operating system you work with.
*: Ubuntu 16.10 and Windows 10
** If you have access to more than one, please state them and the conditions under which you are granted this access.
**: I have complete access to both the operating systems. However, I prefer using Ubuntu for software development.
* Please estimate an average time per day you will be able to access
** an internet connection
**: 24 Hours
** a computer
**: 24 hours
** a computer with your progressing work on
**: 24 hours
* Please describe the degree to which you can install new software on computers you have access to.
*: I have complete root/administrator access.

== S: Self-assessment ==
* Please describe how useful criticism looks from your point of view as committing student.
*: I think constructive criticism plays a vital role in developing a good product. 
*: I like receiving criticism because it means that my work matters to someone and I take that as motivation to make my work better.  
* How autonomous are you when developing:
*: While assessing myself I observed that I try to code first and then try to find bugs and remove the inefficiencies in my code. 
*: Recently I was working with Colin on this [https://github.com/cbm755/octsympy/pull/749 PR], you can see that my initial changes were very naive and incorrect, but then Colin helped me understand what else could have been done. Then I reimplemented it using the right ideology.
*: I think this methodology is what makes me learn more. I understand this might turn out to be a slow process, but I think this is what makes me more experienced.
*: Thomas Edison said, "'' I haven't failed, I've just found 10,000 ways that won't work. ''"
*: With that said, I will also absolutely make sure that I take regular weekly feedback from my mentors so that I don't end up in a wrong path.

== Y: Your task ==
* Did you select a task from our list of proposals and ideas?
*: Yes, I would like to work on the project: "Symbolic Package" [http://wiki.octave.org/Summer_of_Code_Project_Ideas#Symbolic_package Wiki link to the project]
*: 
* Please provide a rough estimated timeline for your work on the task.
*: During Google Summer of Code, I would work 40 hours per week. This is my rough estimated timeline:
*: '''May 5 - May 30, 2017''' (Community bonding period)
*::# Try to move from 'familiar' to 'proficient' in Octsympy and Pytave.
*::# Contribute as much as I can to Octsympy and Pytave. 
*::# Continuously interact with the mentors and better define the steps to complete the project.
*: '''May 30 - June 30, 2017''' (First term)
*:: '''Week 1-2''': Improve Pytave code
*::# Migrate away from Pytave legacy [https://bitbucket.org/mtmiller/pytave/issues/74/migrate-away-from-remaining-pytave-legacy #74] [https://bitbucket.org/mtmiller/pytave/issues/80/remove-code-for-calling-octave-from-python #80]
*::# Resolve [https://bitbucket.org/mtmiller/pytave/issues/79/sympy-function-objects-cause-errors #79], this causes test failures in Octsympy.
*::# Remove the boost dependencies from Pytave and use native API calls for the same.
*:: '''Week 3-4''': Making @sym a subclass of @pyobject. 
*::# Fix core Octave classdef issues:
*::#: Understand the currently available features of classdef in Octave.
*::#: Fix the bugs related to classdef in core Octave. Some of the major ones that I want to focus on are:
*::#:* [https://savannah.gnu.org/bugs/?49169 49169] Defining a classdef superiorto some other classdef.
*::#:* [https://savannah.gnu.org/bugs/?45833 45833] support load/save of classdef objects.
*::#:* [https://savannah.gnu.org/bugs/?48693 48693] classdef subsref method is not called with correct nargout value.
*::#:* [https://savannah.gnu.org/bugs/?43047 43047] and [https://savannah.gnu.org/bugs/?49169 49169] Documentation problems in classdef (Optional)
*::#: Add more features if feasible. 
*::# Make this [https://github.com/cbm755/octsympy/pull/590 PR] by Abhinav mergeable. (If possible in the time frame)
*::# Discuss and decide which implementation (classic @class style or classdef) style to use for the project.
*: '''July 1 - July 24, 2017''' (Second term)
*::# Make @sym instance a @pyobject instance by calling the constructors, and fixing tests and bugs.
*::# Implement all the class functions required to allow OO style function calling. (e.g. calling f.diff(x, x))
*::# Write tests for the new functionality added.
*::# Optimize the functions in @sym and @symfun to use the OO features added.
*::# Replace the python_cmd interface with the pytave fuctions.
*::## This step wants to directly use pyexec and pycall commands, instead of delegating the task to python_cmd.
*::# Write / Modify tests for the above changes.
*: '''July 28 - August 21, 2017''' (Final term)
*:: '''Week 9-10''': Write Documentation
*::# Complete any pending tasks (if any).
*::# Write documentation for Pytave both user's guide and developer's guide. (This will help in attracting more developers to use Pytave)
*::# Write extensive documentation for Octsympy.
*::# Write documentation for the current implementation of classdef in Octave. (I think this is not completed yet.)
*:: '''Week 10-12''': Fix further issues
*::# Fix issues in Pytave [https://bitbucket.org/mtmiller/pytave/issues?status=new&status=open issue list].
*::# Fix issues in Octsympy [https://github.com/cbm755/octsympy/issues issue list].
*::# Add missing functions and functionality to Octsympy.
*: This is a very rough timeline. The exact steps will become clearer when I do some more discussion with the mentors.
