jQuery remains actively maintained — the 4.x branch sits on main with full support, while 3.x gets critical-only patches and older branches are officially dead unless you pay HeroDevs for commercial support. The build system is practical: `npm run build` produces four output variants across `dist/` and `dist-module/` directories (regular, slim, ESM, and factory mode), and you can strip out individual modules like `ajax`, `effects`, `css`, or `deferred` to trim the bundle. The slim variant alone removes AJAX, animations, and deprecated methods — useful if you're targeting modern browsers where `querySelectorAll` covers most selector needs anyway. Tests run through QUnit with a PHP local server requirement, which feels dated compared to modern no-server test runners. jQuery's cross-environment story (browser, Node, extensions) is genuine and the factory mode is a thoughtful nod to headless/windowless contexts, but the reality is that new projects reach for it less often — the web platform itself has closed most of the gaps jQuery used to fill.

Master programming by recreating your favorite technologies from scratch.

freeCodeCamp is a free, self-paced curriculum for learning to code, published as open source at freeCodeCamp/freeCodeCamp. It's a 501(c)(3) nonprofit funded by donor support, structured around six certifications in its Full-Stack Developer Curriculum, each gated by required projects instead of open-book quizzes. The repository also carries beta language certifications for developers, interview-prep resources, and the code that runs the live freecodecamp.org platform.

Hermes Agent (NousResearch/hermes-agent) is an open-source, self-improving AI agent from Nous Research, written in Python and released under the MIT license. The README describes a closed learning loop, a terminal UI, and a messaging gateway spanning Telegram, Discord, Slack, WhatsApp, and Signal, plus support for running the agent on a VPS, a GPU cluster, or serverless infrastructure.
