Programmer's guide to reddit

Reddit is a great place which if used wisely can work as a great source of information of all sorts. This blog highlights some good subreddits for people who like computers/programming/tech in general. Rather than being a mega subreddit list, this is a curated list that I and some other folks at JODC find interesting.

My two cents

There are many other great subreddits that this post may not include, one of the reason being they are very specific to the reader's interest (or maybe I am unaware of them :P) and I leave it upto the reader to find them. Some general advice on finding good communities for your needs and making most out of them:

Use the sidebar to find related communities.
Some of the communities include a wiki where they list FAQs and general advice. Its a nice refined compilation of the subreddit's threads.
Use thread flairs in the sidebar to filter questions, topics, resources or whatever the community has to offer.
Use custom feeds to keep your main feed clean. Here is how you can make custom feeds for yourself. Use r/multihub to find public feeds/multis.
Keep an eye on the comments. You may find gold there.
Obviously use the search bar or use a search engine to find communities/threads.

r/learnprogramming

A subreddit where people post resources to learn programming including self-written tutorials, course reviews, programmer roadmaps etc. Programming related questions are welcome. Take a look at their faq which is a complete guide on getting started.

r/programming

People sharing their cool programming projects, general thoughts on programming, discussing hot programming topics and other interesting programming stuff. Their faq lists some general questions that every programmer faces at some point.

r/compsci

Rather than being focussed only on programming, this subreddit discusses Computer Science Theory and Application, content that computer scientists find interesting.

r/ProgrammerTIL

A subreddit where programmers share interesting lesser known stuff/facts about programming.

Programming languages subreddits

You can find a subreddit for your beloved language as well. Some popular ones:

You won't want to pollute your feed with unnecessary posts, so join subreddits wisely.
