    Matplot++

    Matplot++

    Matplot++: A C++ Graphics Library for Data Visualization

    Data visualization can help programmers and scientists identify trends in their data and efficiently communicate these results with their peers. Modern C++ is being used for a variety of scientific applications, and this environment can benefit considerably from graphics libraries that attend the typical design goals toward scientific data visualization. Besides the option of exporting results to other environments, the customary alternatives in C++ are either non-dedicated libraries that depend on existing user interfaces or bindings to other languages. Matplot++ is a graphics library for data visualization that provides interactive plotting, means for exporting plots in high-quality formats for scientific publications, a compact syntax consistent with similar libraries, dozens of plot categories with specialized algorithms, multiple coding styles, and supports generic backends.

    OSX Serial Generator

    OSX Serial Generator

    Generate complete sets of Serial Numbers for OSX-KVM, Docker-OSX

    OSX Serial Generator is a shell-based toolkit for generating valid-looking macOS serial numbers, hardware UUIDs, and board serials for use in virtualized macOS environments such as OSX-KVM, Docker-OSX, and OpenCore-based Hackintosh setups. It is positioned for good-faith security and Apple bug bounty research, where having realistic device identifiers is necessary to reproduce issues or test services that validate Apple hardware details. The project provides scripts and configuration templates that automatically fill in placeholders like serial, board serial, UUID, ROM, and even display parameters inside plist files. This means researchers can bring up many different “machines” with distinct identities without manually hunting for serial ranges or crafting XML by hand. It is designed to integrate smoothly with other SickCodes projects, particularly Docker-OSX, so that automated builds can generate and inject unique identifiers during container creation.

    Official Android SDK for Stream Chat

    Official Android SDK for Stream Chat

    Android Chat SDK ➜ Stream Chat API. UI component libraries for chat

    This is the official Android SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level chat SDK and a set of reusable UI components. Most users start with the UI components and fall back to the lower-level API when they want to customize things. We're proud to say that we're the first Android Chat SDK that supports Jetpack Compose! We released our Compose UI Components one day after the official Jetpack Compose 1.0 release and our team members have been working hard on it since then. Now it's mature and stable enough for us to officially recommend it for all new applications and all modern chat implementations. If you're looking for something highly customizable and extremely performant, check out our Compose SDK.

    OpenAI Cookbook

    OpenAI Cookbook

    Examples and guides for using the OpenAI API

    openai-cookbook is a repository containing example code, tutorials, and guidance for how to build real applications on top of the OpenAI API. It covers a wide range of use cases: prompt engineering, embeddings and semantic search, fine-tuning, agent architectures, function calling, working with images, chat workflows, and more. The content is primarily in Python (notebooks, scripts), but the conceptual guidance is applicable across languages. The repository is kept up to date and often expanded, and its examples are intended to serve both beginners and intermediate users of the API. It also includes deployment recipes, integration snippets (e.g. with GitHub Actions), and production considerations. Because OpenAI’s API evolves rapidly, the Cookbook acts as a living, community-curated reference to show “how to do X with the API” rather than only reprinting documentation.
