    Concise CLI

    Concise CLI

    A CSS framework that's lightweight and easy-to-use

    The Concise CLI can be used independently of any styles. In principle, it would will with any other CSS library, framework or any existing project so long as the code is plain CSS or contains only the features that can be compiled with PostCSS. Of course, one can start writing everything from scratch using Concise as well. The core library contains the very basic styles that one might use, and contains most of the code that was available on Concise v4. No unnecessary styles are added so you can spend more time building and less time overriding. Do you need CSS components? We provide a basic UI kit for Concise CSS as an add-on. We also provide utility classes for rapid prototyping and context-dependent styles. The usual features from Sass with some custom additions using PostCSS. A framework built with design in mind. Get better results from the beginning with less code.

    CrypTen

    CrypTen

    A framework for Privacy Preserving Machine Learning

    CrypTen is a research framework developed by Facebook Research for privacy-preserving machine learning built directly on top of PyTorch. It provides a secure and intuitive environment for performing computations on encrypted data using Secure Multiparty Computation (SMPC). Designed to make secure computation accessible to machine learning practitioners, CrypTen introduces a CrypTensor object that behaves like a regular PyTorch tensor, allowing users to seamlessly apply automatic differentiation and neural network operations. Its design mirrors PyTorch’s modular and library-based structure, enabling flexible experimentation, debugging, and model development. The framework supports both encryption and decryption of tensors and operations such as addition and multiplication over encrypted values. Although not yet production-ready, CrypTen focuses on advancing real-world secure ML applications, such as training and inference over private datasets, without exposing sensitive data.

    The concept behind DataWoo is to create a Spring-based architecture that allows developers to jump-start their coding efforts by providing a hardened and secure foundation when developing new systems; it can also be used as a reference for incorporating new technologies into existing systems. DataWoo is meant to be a research and development platform that can be extended into just about any enterprise-level web application. The architecture will be developed in three phases: 1. Basic Spring Architecture: Provides all the basic components needed to field an enterprise-level application. 2. Programmatic Security Model: Incorporates the components needed to dynamically assign users to user roles and user roles to profiles. 3. Meta-Driven Architecture: Use meta-data to dynamically configure 80%-90% of the application using the concepts exemplified in the Compiere open source project.

    Derby

    Derby

    MVC framework making it easy to write collaborative applications

    The Derby MVC framework makes it easy to write realtime, collaborative applications that run in both Node.js and browsers. Derby includes a powerful data synchronization engine called Racer that automatically syncs data among browsers, servers, and a database. Models subscribe to changes on specific objects, enabling granular control of data propagation without defining channels. Racer supports offline usage and conflict resolution out of the box, which greatly simplifies writing multi-user applications. Derby applications load immediately and can be indexed by search engines, because the same templates render on both server and client. In addition, templates define bindings, which instantly update the view when the model changes and vice versa. Derby makes it simple to write applications that load as fast as a search engine, are as interactive as a document editor, and work offline.

    Detox

    Detox

    Gray box end-to-end testing and automation framework for mobile apps

    High velocity native mobile development requires us to adopt continuous integration workflows, which means our reliance on manual QA has to drop significantly. Detox tests your mobile app while it's running in a real device/simulator, interacting with it just like a real user. The most difficult part of automated testing on mobile is the tip of the testing pyramid - E2E. The core problem with E2E tests is flakiness, tests are usually not deterministic. We believe the only way to tackle flakiness head on is by moving from black box testing to gray box testing. That's where Detox comes into play. Detox is built from the ground up to support React Native projects as well as pure native ones. Read the Getting Started Guide to get Detox running on your app in less than 10 minutes. We believe that the only way to address the core difficulties with mobile end-to-end testing is by rethinking some of the principles of the entire approach.
