The supported data models can be mixed in queries and allow ArangoDB to be the aggregation point for your data.
AREG SDK is an interface-centric real-time asynchronous communication engine to enable distributed- and mist-computing, where Things interact and provide services, as if they act like thin distributed servers.
Traditionally, devices are connected clients to stream data to the cloud or fog servers for further processing. Since data is generated and collected at the edge of the network (mist network), it makes sense to change the role of connected Things and provide network accessible (Public) services directly on devices. This extends Cloud to the extreme edge.
Bitcoin is an innovative payment network and a new kind of money. Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.

Lina's architecture is designed to be as modular as possible and it focuses on creating replacable modules to customize for project-specific needs, rather than stacking thousands of features into one framework.
Lithium is the fastest open-source HTTP framework written in c++17. Lithium HTTP server and SQL drivers are benchmarked againts 200+ other framesworks at TechEmpower . As of November 2020, it is ranked first. Pre-2010 C++ was a pretty low-level language and zero-runtime-cost abstractions where only possible using complex template meta-programming tricks. The C++ standard committee addressed those issues by publishing new C++ standard, making C++ programs much more simpler and fun to write. These recent language evolutions has created inside the language a C++ subset that is easy to grasp for beginners and less error prone than C++ itself: using RAII instead of manual memory management, using constexpr instead of template meta-programming, etc... Could this subset of C++ lead to a web framework that is as easy to grasp than javascript alternatives while keeping the performances of C++ ? The goal of Lithium is to prove that this is feasible.
MXNet is a deep learning framework designed for both efficiency and flexibility. It allows you to mix the flavours of symbolic programming and imperative programming to maximize efficiency and productivity. In its core, a dynamic dependency scheduler that automatically parallelizes both symbolic and imperative operations on the fly. A graph optimization layer on top of that makes symbolic execution fast and memory efficient. The library is portable and lightweight, and it scales to multiple GPUs and multiple machines.
Ogre3D is one of the most popular open-source graphics rendering engines, and has been used in a large number of production projects, in such diverse areas as games, simulators, educational software, interactive art, scientific visualisation, and others.
OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products. Being a BSD-licensed product, OpenCV makes it easy for businesses to utilize and modify the code.
openFrameworks is an open source C++ toolkit for creative coding. It includes tools for 2D/3D graphics, audio, and video components along with many addons for integrations with everything from XBOX Kinects to OpenCV.

Pony is an open-source, actor-model, capabilities-secure, high performance programming language.
Hello World in Pony:
actor Main
new create(env: Env) =>
env.out.print("Hello, world!")Proxygen. This project comprises the core C++ HTTP abstractions used at Facebook. Internally, it is used as the basis for building many HTTP servers, proxies, and clients. This release focuses on the common HTTP abstractions and our simple HTTPServer framework. Future releases will provide simple client APIs as well. The framework supports HTTP/1.1, SPDY/3, SPDY/3.1, and HTTP/2. The goal is to provide a simple, performant, and modern C++ HTTP library.
