How can one initiate involvement in open source contribution?
3 by sg2435 | 2 comments on Hacker News.
I have been in the software engineering field for over four years, yet I haven't contributed to any open-source platforms. With the AI field expanding and numerous open-source opportunities emerging, how can I begin contributing? Where should I look or what criteria should I consider when seeking places to contribute code?
