The Algorithms - Python is an open-source collection of algorithm implementations written in Python, maintained by the TheAlgorithms organization on GitHub. The README frames the whole project as a teaching resource: the code exists to illustrate concepts, can run slower than Python's built-in equivalents, and is indexed in DIRECTORY.md for browsing. It's MIT licensed and available on GitHub.

Awesome Go, maintained at avelino/awesome-go, groups Go frameworks, libraries, and software into topic categories including Actor Model, Artificial Intelligence, Audio and Music, Authentication and Authorization, Blockchain, Bot Building, and Build Automation. Every linked entry gets a short description instead of a bare URL. The repository carries an MIT license and takes new entries through pull requests reviewed against its own contribution guidelines, which makes it a common bookmark for day-to-day Go development.

Java Design Patterns is an open-source GitHub project by iluwatar that documents design patterns as commented, working Java code rather than diagrams or prose. The repository is organized so readers can find a pattern by name, by tag such as Gang of Four or Performance, or by category, with a companion site and an optional paid e-book alongside it.

Django (django/django on GitHub) is a Python web framework, released under the BSD-3-Clause license. The README describes it as high-level and built for rapid, pragmatic development, and its GitHub topics — apps, models, orm, templates, views — mark out an ORM, a templating system, and a views layer bundled into one apps-based project structure. Documentation, a Discord community, a Forum, and a formal ticket system for doc issues are all pointed to directly from the README.
