[GSoC 2023] Re: Regarding contribution to Commons Numbers Project under GSoC 2023
Hi Manav, Thanks for your interest in Apache Commons. At present we do not know if there will be projects with Apache Commons for the GSoC 2023 season. If we do have any projects then we will post them with appropriate labels on our issue tracking system so they can be easily found, see for example [1] for the 2022 project in Numbers. The label will be the same across all Apache projects so it will allow you to search more than just Commons projects. In the meantime there are many open tickets in the issue tracking system for Apache projects. Please take a look and if you find anything of interest then contact the appropriate project if you wish to contribute.

Re: [GEOMETRY] Quickhull Implementation
Hello,
thank you very much! I am looking forward to your review comments since
this is my first time trying to contribute to an open source project. I
also noticed a few things with my code, that should be corrected. Some
comments don’t make sense and there shouldn’t be any need for ordering the
edges like i do right now in my current implementation. Also I think the
code should then be refactored to fit better the desired API design. Also a
discussion should be held if face merging is necessary.
Greetings
Andreas

Regarding contribution to Commons Numbers Project under GSoC 2023
Respected Sir/Ma’am, My name is Manav P Gondalia, and I am writing to express my interest in participating in Google Summer of Code and contributing to the project "Common Numbers" under Apache Software Foundation. I have been following Apache Software Foundation’s development for several months now and I am impressed with the impact it has made on the open-source community as well as how much it is loved by the developer community. I am currently a pre-final year undergraduate student in Computer Science and Engineering (CSE) pursuing my BTech from the Indian Institute of Technology(IIT), Patna and I have a strong background in C++, Data Structures and Algorithms and Competitive Programming and Mathematics. I had secured an All India Rank of 2535 in the prestigious JEE-Advanced examination in 2020. I have a keen interest for Mathematics and Programmin from a very young age. I request you to provide me with some starting guides/resources to begin with contributing to this project. I am confident that my skills and passion will allow me to make a meaningful contributions. Following are the links to my CP and GitHub profiles: https://codeforces.com/profile/NineFathoms https://www.codechef.com/users/ninefathoms https://atcoder.jp/users/NineFathoms https://www.hackerrank.com/gondaliamanav https://github.com/manavgondalia Thank you for your time and consideration.
