  • Please state the timeframe (in UTC+0) when you feel most comfortable working during GSoC. Where are your time buffers?
    I can work from 4:30 AM - 11:30 AM (in UTC+0)
    I can also work from 1:00 PM-4:00 PM(in UTC+0) if my project requires it.

E: Coding experience[edit]

This part is one of the more important ones in your application. You are allowed to be as verbose as you want, as long as you stay on topic ;-)

  • Please describe your experience with C++, Octave or Matlab m-scripts, OpenGL and Qt.
    C++
    • I have 5 years of coding experience in C & C++. I have a thorough undertanding of classes and Object Oriented Programming in C++.

F: Feeling fine[edit]

  • 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: 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[edit]

  • 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: link.
    Apart from this, the Octave manual has been very helpful with useful examples to understand concepts.

P: Prerequisites[edit]

  • 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[edit]

  • 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 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[edit]

  • Did you select a task from our list of proposals and ideas?
    Yes, I would like to work on the project: "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)
    1. Try to move from 'familiar' to 'proficient' in Octsympy and Pytave code base.
    2. I will make efforts to learn more about Python/C api so as to contribute more to Pytave to remove boost depedencies.
    3. Contribute as much as I can to Octsympy.
    4. 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
    1. Migrate away from Pytave legacy #74 #80
    2. Resolve #79, this causes test failures in Octsympy.
    3. Remove the boost dependencies from Pytave and use native API calls for the same.
    Week 3-4: Making @sym a subclass of @pyobject.
    1. 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:
      • 49169 Defining a classdef superiorto some other classdef.
      • 45833 support load/save of classdef objects.
      • 48693 classdef subsref method is not called with correct nargout value.
      • 43047 and 49169 Documentation problems in classdef (Optional)
      Add more features if feasible.
    2. Make this PR by Abhinav mergeable. (If possible in the time frame)
    3. Discuss and decide which implementation (classic @class style or classdef) style to use for the project.
    July 1 - July 24, 2017 (Second term)
    1. Make @sym instance a @pyobject instance by calling the constructors, and fixing tests and bugs.
    2. Implement all the class functions required to allow OO style function calling. (e.g. calling f.diff(x, x))
    3. Write tests for the new functionality added.
    4. Optimize the functions in @sym and @symfun to use the OO features added.
    5. Replace the python_cmd interface with the pytave fuctions.
      1. This step wants to directly use pyexec and pycall commands, instead of delegating the task to python_cmd.
    6. Write / Modify tests for the above changes.
    July 28 - August 21, 2017 (Final term)
    Week 9-10: Write Documentation
    1. Complete any pending tasks (if any).
    2. Write documentation for Pytave both user's guide and developer's guide. (This will help in attracting more developers to use Pytave)
    3. Write extensive documentation for Octsympy.
    4. Write documentation for the current implementation of classdef in Octave. (I think this is not completed yet.)
    Week 10-12: Fix further issues
    1. Fix issues in Pytave issue list.
    2. Fix issues in Octsympy issue list.
    3. 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.
