Zopfli
Zopfli Compression Algorithm is a compression library
Zopfli is a compression library and command-line tool that produces exceptionally small DEFLATE, zlib, and gzip streams by spending more CPU time to search for better encodings. It keeps strict compatibility with the ubiquitous DEFLATE format, so outputs can be decompressed by any standard tool or browser. The encoder performs exhaustive block splitting and greedy but thorough match searching to shave extra bytes off assets, which is ideal for web content and firmware where size matters more than compression time. A companion utility, zopflipng, targets PNGs by trying alternate filter strategies and recompressing IDAT chunks, often achieving additional savings without changing image quality. The codebase includes both a reusable library and ready-to-use CLI tools for bulk optimization in build pipelines. It is frequently used offline—e.g., as a final step in release builds—because decode speed remains normal while files get smaller. -

clash-rules
Clash Premium rule set (RULE-SET), compatible with ClashX Pro
clash-rules is a repository that provides rule sets and configuration files designed for proxy tools and systems like V2Ray / Clash — helping users to decide routing, blocking, or proxy behavior based on domain, IP, or other criteria. The repo aggregates many community-maintained lists: blocked domains, direct access lists, proxy-needed domains, geo-IP lists, and more — offering up-to-date and curated configuration data that reflects network conditions, censorship lists, or desirable routing policies. For users of proxy tools or privacy/VPN systems, having such rule lists saves the manual effort of compiling blacklists, whitelists, or routing rules, and helps ensure more reliable, consistent routing and access. The rules are maintained in text-based formats, making them easy to inspect, edit, or integrate into proxy configurations. Because the repository is publicly available, the community can contribute updates (e.g. newly blocked domains, improved routing heuristics). -

edgetunnel
edgetunnel 2.0 VLESS/Trojan
edgetunnel is a modified version of a serverless tunnelling solution designed to run on platforms like Cloudflare Workers and Pages, enabling protocols such as VLESS and Trojan to be exposed through edge-functions rather than traditional servers. The project’s fork by cmliu emphasizes conversion of protocol configuration (especially VLESS) into subscription links, so that users can deploy and then generate “Clash” or “Sing-box” compatible subscription content easily. It provides a streamlined way to host proxy endpoints without managing a full server stack, instead leveraging the edge network of Cloudflare for distribution and potential performance. Because it runs at the edge, latency can be minimized and deployment complexity simplified; users supply configuration variables (host, port, UUID, path) and the script handles mapping to technical protocols and subscription formatting. -

jQuery Validation Plugin
jQuery Validation Plugin library sources
The jQuery Validation Plugin provides drop-in validation for your existing forms, while making all kinds of customizations to fit your application really easy. This jQuery plugin makes simple clientside form validation easy, whilst still offering plenty of customization options. It makes a good choice if you’re building something new from scratch, but also when you’re trying to integrate something into an existing application with lots of existing markup. The plugin comes bundled with a useful set of validation methods, including URL and email validation, while providing an API to write your own methods. All bundled methods come with default error messages in english and translations into 37 other languages. The plugin was initially written and maintained by Jörn Zaefferer, a member of the jQuery team, lead developer on the jQuery UI team and maintainer of QUnit. It was started back in the early days of jQuery in 2006, and updated and improved since then. -

linuxdeployqt
Makes Linux applications self-contained by copying in the libraries
Makes Linux applications self-contained by copying in the libraries and plugins that the application uses, and optionally generates an AppImage. Can be used for Qt and other applications. This Linux Deployment Tool, linuxdeployqt, takes an application as input and makes it self-contained by copying in the resources that the application uses (like libraries, graphics, and plugins) into a bundle. The resulting bundle can be distributed as an AppDir or as an AppImage to users, or can be put into cross-distribution packages. It can be used as part of the build process to deploy applications written in C, C++, and other compiled languages with systems like CMake, qmake, and make. When used on Qt-based applications, it can bundle a specific minimal subset of Qt required to run the application. This tool is conceptually based on the Mac Deployment Tool, macdeployqt in the tools applications of the Qt Toolkit, but has been changed to a slightly different logic. -

minizip-ng
Fork of the zip manipulation library found in the zlib distribution
minizip-ng is a zip manipulation library written in C that is supported on Windows, macOS, and Linux. Minizip was originally developed by Gilles Vollant in 1998. It was first included in the zlib distribution as an additional code contribution starting in zlib 1.1.2. Since that time, it has been continually improved upon and contributed to by many people. The original project can still be found in the zlib distribution that is maintained by Mark Adler. The motivation behind this repository has been the need for new features and bug fixes to the original library which had not been maintained for a long period of time. The code has been largely refactored and rewritten in order to help improve maintainability and readability. A compatibility layer has been provided for consumers of the original minizip library. -

tmi.js
Javascript library for the Twitch Messaging Interface
Connect to and interact with Twitch chat (IRC) from Node.js or a browser. Control the delay in milliseconds between JOIN requests when using the channels array option. Minimum of 300 milliseconds. If the identity has special permission from Twitch for a higher join rate then you should implement your own calls to the client.join method. Disable receiving JOIN/PART events for other users. Good for decreasing network traffic when joining lots of channels or you don't care about this data. After a threshold per channel Twitch stops sending this data so it may not be necessary for all cases. Channels to automatically join upon connecting. The rate of joins is controlled by the options.joinInterval option. Automatically reconnect the client if it gets disconnected for any reason. Sometimes Twitch will request the client to reconnect and tmi.js will disconnect and reconnect even if this option is set to false. -

Arduino FOC
Arduino FOC for BLDC and Stepper motors
We live in very exciting times 😃! BLDC motors are entering the hobby community more and more and many great projects have already emerged leveraging their far superior dynamics and power capabilities. BLDC motors have numerous advantages over regular DC motors but they have one big disadvantage, the complexity of control. Even though it has become relatively easy to design and manufacture PCBs and create our own hardware solutions for driving BLDC motors the proper low-cost solutions are yet to come. One of the reasons for this is the apparent complexity of writing the BLDC driving algorithms, Field oriented control (FOC) being an example of one of the most efficient ones. The solutions that can be found online are almost exclusively very specific for certain hardware configurations and the microcontroller architecture used. Additionally, most of the efforts at this moment are still channeled towards the high-power applications of the BLDC motors and proper low-cost FOC. -

CodeQL
Libraries and queries that power security researchers
CodeQL is a semantic code analysis engine that treats programs as queryable databases, enabling users to write expressive queries that identify security vulnerabilities, logic bugs, and code quality issues across large codebases. Instead of just pattern matching text, CodeQL ingests source code, builds rich representations of structure and data flow, and allows queries that reason about control flow, type systems, and interprocedural relationships. This makes it powerful not just for basic linting but for deep detection of complex security flaws like SQL injection, cross-site scripting, and taint propagation that traditional static analyzers can miss. CodeQL is used by security teams, developers, and open-source tooling to create reusable query libraries, enforce policy across repositories, and automate findings in CI/CD pipelines. -
