EbookFoundation/free-programming-books is a community-curated index of free learning materials for developers. What began as a Stack Overflow list has grown into a comprehensive resource, now overseen by the Free Ebook Foundation. It categorizes a wide range of content, including books by language and subject, free online courses, cheat sheets, interactive programming tutorials, problem sets, podcasts, screencasts, and browser-based programming playgrounds. Many of these resources are available in dozens of languages beyond English, and you can navigate the collection through its dedicated search website or by browsing the repository's markdown files.

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 has 223,712 stars and 50,966 forks 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, has 180,946 stars and 13,482 forks on GitHub, 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.
