[rsapkf/42]

This is an ongoing personal collection of over 5000+ sites and resources that I use or have used in the past to learn programming, puzzle-solving, web development and other intellectually stimulating things, categorized (more or less). Contains my blogroll, websites, software, Reddit/YouTube subscriptions, Medium/DEV.to blogs, IRC channels, HN/Lobste.rs/Stack Overflow/Codepen profiles/articles I follow, podcasts, browser add-ons, Linux tools, Vim/tmux/Emacs plugins I use and everything.

In short, this is my attempt to organize my links, a directory of my "public" bookmarks. Feedback and contributions are appreciated.

Disclaimer: The categorization of resources and software that I list here are for personal reference only. Not every open source software out there is more secure than other proprietary options. Please do a thorough research before using any of this stuff.

Roadmap

• Dynamic website with tagging system and a full featured public API.
• Browser (Firefox/Chromium) extensions to see other similar sites in this collection like the one you're in right now.
• CLI tool to access the collection from the terminal.
