This is an ongoing personal collection of over 2000+ sites and resources that I use or have used in the past to learn stuff like programming, puzzle-solving, web development and other intellectually stimulating things, categorized(more or less). Most of these are from my browser bookmarks. Contains blogs, websites, my GitHub stars(which I manage with my bookmark manager, not GH itself), subreddits, YouTube channels, Medium/dev.to blogs, IRC channels and everything. Feel free to contribute by adding more resources!
