    FanCtrl

    FanCtrl

    FanCtrl allows you to automatically control the fan speed

    FanCtrl is a Windows desktop utility focused on automatically controlling PC fan speeds using temperature sensors and customizable fan curves, so your cooling behavior matches how you actually use your system. It combines monitoring and control in one place, letting you view temperatures, fan RPM, and control percentages while you tune how aggressively each fan responds. The project supports a range of control backends and integrations, including motherboard fan headers and several popular cooling ecosystems, and it can also pull sensor data from common monitoring tools so your fan logic can react to the readings you trust. A core concept is “auto fan control” profiles where you pick a target temperature sensor, select which fans should follow it, and then shape the curve via a graph-like interface. It also includes quality-of-life options like renaming items, choosing units (including Fahrenheit), and starting minimized for a set-it-and-forget-it setup.

    Sims 3 Package Interface

    Sims 3 (and other) game package library

    "Sims 3 Package Interface" provides a core library of portable code that "understands" Sims3 game packages. Note that (with some minor tweaks) the core library code also understands other game package formats (e.g. SimCity Online, Sims4). Along with the core library are a number of "wrappers" that provide the main part of the project. These handle deserialization and serialization of data within the package (or any other source). Further tools (not supplied here) can use the core library and wrappers to manipulate the data content of package files. Note that development on this library and wrappers provided here has now finished.

    The OpenAPI.NET SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model. The OpenAPI.NET project holds the base object model for representing OpenAPI documents as .NET objects. Some developers have found the need to write processors that convert other data formats into this OpenAPI.NET object model. We'd like to curate that list of processors in this section of the readme. Converts standard .NET annotations ( /// comments ) emitted from your build (MSBuild.exe) into OpenAPI.NET document object. Converts the XML representation of the Entity Data Model (EDM) describing an OData Service into OpenAPI.NET document object.

    Unity-MCP is an open-source integration that connects artificial intelligence assistants with the Unity game development environment through the Model Context Protocol. The project enables AI tools such as coding assistants and autonomous agents to interact directly with Unity projects, allowing them to analyze scenes, modify assets, and generate code within the development environment. By exposing Unity editor functionality through MCP tools, the plugin allows external AI systems to understand the structure of a game project and manipulate it programmatically. Developers can use natural language prompts to instruct AI assistants to create objects, modify scenes, or generate gameplay scripts automatically. The system supports both editor-level automation and runtime integration, meaning AI models can also be used inside compiled games for dynamic behavior such as interactive characters or debugging tools.
