    ChromiumFX

    ChromiumFX

    .NET bindings for the Chromium Embedded Framework

    ChromiumFX is a .NET-based framework that embeds the Chromium browser engine into desktop applications, allowing developers to integrate modern web technologies into native software environments. It acts as a bridge between the Chromium Embedded Framework (CEF) and .NET applications, providing a managed interface that simplifies interaction with browser components. The project enables developers to render web content, execute JavaScript, and build hybrid applications that combine native performance with web-based interfaces. It is particularly useful for creating rich user interfaces, dashboards, or tools that rely on HTML, CSS, and JavaScript while still running as desktop applications. ChromiumFX abstracts much of the complexity of working directly with CEF, making it easier to embed browser functionality without dealing with low-level implementation details.

    Clair

    Clair

    Vulnerability Static Analysis for Containers

    Clair is an application for parsing image contents and reporting vulnerabilities affecting the contents. This is done via static analysis and not at runtime. Clair v4 utilizes the ClairCore library as its engine for examining contents and reporting vulnerabilities. At a high level you can consider Clair a service wrapper to the functionality provided in the ClairCore library. The main branch may be in an unstable or even broken state during development. Please use releases instead of the main branch in order to get stable binaries. Clair is an open source project for the static analysis of vulnerabilities in application containers (currently including OCI and docker). Clients use the Clair API to index their container images and can then match it against known vulnerabilities. Our goal is to enable a more transparent view of the security of container-based infrastructure. Thus, the project was named Clair after the French term which translates to clear, bright, transparent.

    ClassyVision

    ClassyVision

    An end-to-end PyTorch framework for image and video classification

    Classy Vision is a PyTorch-based framework designed for large-scale training and deployment of state-of-the-art image and video classification models. Developed by Facebook Research, it serves as an end-to-end system that simplifies the process of training at scale, reducing redundancy and friction in moving from research to production. Unlike traditional computer vision libraries that focus solely on modular components, Classy Vision provides a complete and unified framework, featuring distributed training, reproducible experiments, and flexible configuration tools. It offers high performance and scalability—capable of training models like ResNet-50 on ImageNet in just minutes—while remaining accessible to both researchers and production engineers. The library integrates seamlessly with PyTorch Hub for easy access to pretrained models and supports elastic training using PyTorch Elastic, making distributed training robust to changes in cluster resources or hardware failures.

    Claudia Bot Builder

    Claudia Bot Builder

    Create chat bots for Facebook Messenger, Slack, Amazon Alexa, etc.

    Claudia Bot Builder helps developers create and deploy chat-bots for various platforms in minutes to AWS Lambda. It simplifies the messaging workflows, automatically sets up the correct web hooks, and guides you through configuration steps, so that you can focus on important business problems and not have to worry about infrastructure code. This code is enough to operate bots for all supported platforms. Claudia Bot Builder automatically parses the incoming messages into a common format, so you can handle it easily. It also automatically packages the response into the correct message template for the requesting bot, so you do not have to worry about individual bot protocols. Claudia Bot Builder doesn't have a stand-alone http server in the background (such as Express, Hapi, etc.), instead it uses API Gateway and it's not trivial to simulate similar environment locally. Deploy it with --version test to create a separate test environment directly in AWS Lambda.

    Clean Architecture Solution Template

    Clean Architecture Solution Template

    Clean Architecture Solution Template for .NET 6

    This is a solution template for creating a Single Page App (SPA) with Angular and ASP.NET Core following the principles of Clean Architecture. Create a new project based on this template by clicking the above Use this template button or by installing and running the associated NuGet package (see Getting Started for full details). The template is configured to use an in-memory database by default. This ensures that all users will be able to run the solution without needing to set up additional infrastructure (e.g. SQL Server). Verify that the DefaultConnection connection string within appsettings.json points to a valid SQL Server instance. When you run the application the database will be automatically created (if necessary) and the latest migrations will be applied. This will contain all entities, enums, exceptions, interfaces, types and logic specific to the domain layer.

    Clerk

    Clerk

    Moldable Live Programming for Clojure

    Clerk is a notebook library for Clojure that enables interactive, reproducible, and version-control-friendly live programming. Notebook content is written in standard Clojure namespaces or Markdown with embedded Clojure code blocks and evaluates top-to-bottom for predictable behavior. Clerk notebooks are either regular Clojure namespaces (interspersed with markdown comments) or regular markdown files (interspersed with Clojure code fences). This also means Clerk notebooks are meant to be stored in source control. Clerk notebooks always evaluate from top to bottom. Clerk builds a dependency graph of Clojure vars and only recomputes the needed changes to keep the feedback loop fast.
