Plus, I could see myself using this tool for my own work. | ||

It involved reading a bunch of papers on dynamic subgrid scale modeling (small-scale turbulence modeling), understanding a big piece of code written by someone else and changing (also adding new features) it to C++, which I didn't know much of until I started working on this project. | ||
The complexity of the code and poor documentation, made it quite challenging to add new pieces of code that worked in sync with the rest of it. It taught me the value of having a clear plan of action before implementation and the importance of testing vigorously. I found it useful at times to discuss certain aspects with more experienced users and refining my thought process. | The complexity of the code and poor documentation, made it quite challenging to add new pieces of code that worked in sync with the rest of it.

I think I've learned a few things just by hanging around in IRC, reading mailing digests regularly and submitting small patches. I view it as an experience which not only improves the coding skills, but the intangible ones as well. Other members seem helpful and welcoming. Besides I use Matlab pretty frequently, but I'am trying to switch to Octave. It's a very helpful tool for my research (which is not going to change any time soon). A combination of all these things makes me want to stick around after GSoC is over. | |||

I' | I'd like to know the source code and community better by getting more involved in help-forums, IRC, etc. I wouldn't have my research commitments in May and that should help. I'd also like to discuss the frequency and means of communication with my mentor. I have set up a blog and would like to put my weekly/fortnightly progress on it. Also, I think this project is more math-intensive than coding-intensive, so it's important I know the theory behind implementation well. <br> | ||
