Free Programming Books (Chinese) is justjavac's GitHub index of free programming books, translated manuals, and course notes in Chinese, organized under headings like AI, Go, C/C++, and version control. It's a link list, not a curriculum - entries range from full book translations to single blog posts, some flagged `:worried:` for dead links, and contribution happens only through pull requests.

Joplin is an open-source, privacy-focused note-taking application built with TypeScript that prioritizes offline access and user data ownership. It stores notes in Markdown format and supports end-to-end encrypted synchronization with Nextcloud, Dropbox, OneDrive, or Joplin Cloud, meaning your data stays under your control without vendor lock-in. The application handles large note collections organized into notebooks with full-text search across all platforms (Windows, macOS, Linux, Android, iOS), and includes a Web Clipper for Firefox and Chrome to capture web content directly. What sets Joplin apart is its extensibility through plugins and themes, plus the ability to import directly from Evernote including formatted content and metadata — a genuine migration path for users leaving proprietary ecosystems. The offline-first architecture ensures notes remain accessible without internet connectivity, which matters for users in regions with unreliable connections or those who simply prefer not to depend on cloud availability.
