Project Jupyter was born out of the IPython Project in 2014 as it evolved to support interactive data science and scientific computing across all programming languages.

My Work

Started with a introduction by Katy Huff to figure out the technicalities of submitting a pull request to the actual copy.(arfc/hipython#2).

Subsequently, I tried my hands on the jupyter project. I identified a beginner friendly issue with Jupyter notebook (http://jupyter.org/) which I could start with. It involved reading several issues and the codebase to identify the problem and making the necessary changes.

The issue was a bugfix in nb and server extensions where server extensions were not loaded when installed to different locations. (jupyter/notebook#2063) The solution was solved by modifiying to load with Config Manager so that the merge happens recursively by minrk (https://github.com/jupyter/noteb
