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.

Termux is an Android terminal emulator that gives you a working Linux shell environment on your phone, backed by a separate package repository that supplies familiar tools like bash, git, python, and node. The core app handles terminal emulation and UI while optional plugins add capabilities like API access, boot scripts, floating windows, and Tasker integration—you cannot mix APKs from different sources since each signs with different keys, which catches newcomers off guard. The project is actively seeking maintainers, which signals the kind of maintenance burden to expect. Android 12+ users hit real stability problems from OS-level phantom process killing, a documented gotcha that the README explicitly calls out. Installation source matters significantly: GitHub builds include a critical security fix from v0.118.0 but use an exposed test signing key (everyone can forge updates), F-Droid builds lag by days to weeks, and the Google Play version is experimental with missing functionality. The debugging story is solid—built-in log level controls and a "Report Issue" feature that bundles diagnostics automatically, which actually makes bug reports useful.

Win11Debloat is a single PowerShell script that removes bloatware, disables telemetry, and applies a long list of Windows UI and system tweaks without installing anything. You can run it either by pasting a one-liner into PowerShell or by downloading the ZIP and executing the included batch file — both methods require admin rights. The script covers app removal, privacy toggles (telemetry, location, ads), AI feature disabling (Copilot, Recall, Click to Do), and dozens of cosmetic and behavioral changes like restoring the old context menu, disabling transparency, and customizing the taskbar. Almost every change is reversible, and you can export your configuration to apply it across multiple machines, which makes it useful for sysadmins imaging machines. The catch is that this is directly editing the registry and removing system components — the README itself warns to use at your own risk, and if something breaks you'll need to manually revert or reinstall affected apps from the Microsoft Store.

A collaborative GitHub list linking to open-source apps across iOS, iPadOS, watchOS, tvOS, and visionOS, grouped into categories like Browser, Communication, and Clone, with each entry tagged by year and language.
