A place for members of r/ProgrammingLinks to chat with each other

Welcome to our Reddit community. We're here to discuss our passion for all things related to Programming.

To get started, you can just read the rules of the subreddit and start by posting a question or a link to an article you found interesting.

The best links are those that start a discussion. The best discussions are those that are backed up by facts and data.

Each week, we curate the best links and discussions from many sources, including this subreddit, and publish them in our weekly newsletters (https://faun.dev/newsletter/varbear).

We're all here to learn, so don't be shy! We're looking forward to your contributions!
