    Lua

    Lua

    The Lua development repository, as seen by the Lua team

    Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode with a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping. Lua is designed, implemented, and maintained by a team at PUC-Rio, the Pontifical Catholic University of Rio de Janeiro in Brazil. Lua was born and raised in Tecgraf, formerly the Computer Graphics Technology Group of PUC-Rio. Lua is now housed at LabLua, a laboratory of the Department of Computer Science of PUC-Rio.

    Battery Historian

    Battery Historian

    Battery Historian is a tool to analyze battery consumers using Android

    Battery Historian is a visualization and analysis tool for Android power usage that turns raw bugreport and batterystats data into actionable timelines. Developers upload a bugreport and get interactive graphs that show wakelocks, jobs, alarms, network activity, CPU states, screen usage, and app-level events. By correlating these signals, it helps identify abusive wakeups, runaway services, or networking patterns that drain battery. The UI supports zooming into problem windows, filtering by UID or tag, and comparing multiple runs to verify improvements. It also surfaces metrics summaries and highlights known anti-patterns so performance teams can focus on the highest-impact fixes. Battery Historian has become a staple in diagnosing real-world battery regressions during app development and system bring-up.

    Betterfox

    Betterfox

    Firefox user.js for optimal privacy and security

    Betterfox is an opinionated configuration profile for Mozilla Firefox designed to improve everyday web browsing by making the browser faster, more private, and more secure without relying on external add-ons or third-party code. Rather than being a separate browser, it consists of a curated set of preference tweaks (user.js settings) that users apply to their Firefox profile to optimize performance and harden privacy settings. The project focuses on a minimal-impact, maximum-effect approach, removing unnecessary background services, reducing fingerprinting, and tightening security defaults while trying to keep sites usable. Betterfox recommends pairing these settings with essential extensions like ad blockers and DNS-level protections to achieve a well-rounded browsing experience. Because the preferences are text-based and version controlled, users can review and customize them to meet their own balance of privacy and convenience.

    Java WebSockets

    Java WebSockets

    A barebones WebSocket client and server implementation

    This repository contains a barebones WebSocket server and client implementation written in 100% Java. The underlying classes are implemented java.nio, which allows for a non-blocking event-driven model (similar to the WebSocket API for web browsers). The org.java_websocket.server.WebSocketServer abstract class implements the server-side of the WebSocket Protocol. A WebSocket server by itself doesn't do anything except establish socket connections though HTTP. After that it's up to your subclass to add purpose. The org.java_websocket.client.WebSocketClient abstract class can connect to valid WebSocket servers. The constructor expects a valid ws:// or wss:// URI to connect to. Important events onOpen, onClose, onMessage and onError get fired throughout the life of the WebSocketClient, and must be implemented in your subclass.
