wxPHP
PHP bindings for the cross-platform GUI library wxWidgets.
wxPHP is a php binding/wrapper for the cross-platform library wxWidgets, which gives you the ability to develop desktop applications using the php programming language. This applications can be executed on windows, linux and macosx using the same code base with a native look and feel. One of the ideas is that you can use your php web applications code base and logic to create native desktop applications that communicate to them transparently. This way you can give your users a seamless and native experience from the desktop while staying in sync with your web apps. There are many more use cases, but we invite you to download and try this project by your self. We hope everyone can enjoy it as much as we have enjoyed developing it. -

Tiny CUDA Neural Networks
Lightning fast C++/CUDA neural network framework
This is a small, self-contained framework for training and querying neural networks. Most notably, it contains a lightning-fast "fully fused" multi-layer perceptron (technical paper), a versatile multiresolution hash encoding (technical paper), as well as support for various other input encodings, losses, and optimizers. We provide a sample application where an image function (x,y) -> (R,G,B) is learned. The fully fused MLP component of this framework requires a very large amount of shared memory in its default configuration. It will likely only work on an RTX 3090, an RTX 2080 Ti, or high-end enterprise GPUs. Lower-end cards must reduce the n_neurons parameter or use the CutlassMLP (better compatibility but slower) instead. tiny-cuda-nn comes with a PyTorch extension that allows using the fast MLPs and input encodings from within a Python context. These bindings can be significantly faster than full Python implementations; in particular for the multiresolution hash encoding. -

libCIGI
C++ Library for the Common Image Generator Interface
libCIGI (library for Common Image Generator Interface) is a lightweight header only library that provides interfaces for communication between CIGI hosts and image generators. Currently versions 3.0, 3.2 and 3.3 are supported as well as support for the *draft* V4.0 CIGI standard. Additional functionality to the base packet interfaces is provided through external classes so that to the packet headers have no further dependencies. Packet processing is kept simple and a couple of simple helper functions / classes are provided in CIGIGeneric.h and some other headers to support this. Helpers are provided for version interpretation and conversion of packet parameters to text. Testing is supported using the boost test framework to develop unit tests for each of the packets. Because the library is header-only it can easily support many platforms / compilers but this has not yet been tested. Note: Currently the use of bitfields in the library may cause erroneous use in some compilers. -

.Net Native Interface Library
The best library to work with .Net Assemblies in any programming lang.
The .Net Native Interface Library (DotNetNativeInterface) is a native programming interface which provides a way for programming languages such as C, C++, Fortran, Assembly, Pascal, Java, VB etc to interact with applications and libraries written in any of the .Net languages (such as C#, VB.Net etc). Programmers can use DotNetNativeInterface native methods to access .Net 3rd party libraries or .Net Framework Libraries without the need for registry entries, COM registrations or changes to the .Net libraries. The following examples illustrate when you need to use DotNetNativeInterface native methods: 1. You want to access and use .Net Framework Class Library in your application. 2. You want to access and use 3rd party .Net Libraries in your application. Competitive Advantages: 1. Access to .Net Framework Class Library. 2. No COM registration of .Net Libraries is required when deployed. 3. Allows any programming language to consume .Net libraries as if they were native code. -

Apparat
C++ library
Apparat is a powerful C++ framework for linux programmers. It presents handy and practical facilities, including following: advanced smart pointers (strong and weak handles), set of containers (array, list, map, sector, cycle buffer, priority queue), own powerful signal/slot mechanism (signal can connect with slots in other threads), functors and functor's map, threads and timers, state machines, input/output streams and serialization, serial port, sockets and so on. Apparat is a set of C++ source files, that can be compiled with your project. Folder 'test' in source tree contains some examples of using Apparat. For assembling your projects I am suggesting my own project management system based on standard 'make'. Root of this system is ingenious 'GNUMakefile' that automatically generates rules for compiling of all files in project's source tree and linking generated object files in executable file or library. See README for details. -

Ash C++ Template Library (AshTL)
Hashing and spatial concurrency library.
AshTL aims to provide a complete framework for dealing with spatial data in an efficient, parallel manner. As such, we primarily provide container classes and data types relating to 2D and 3D coordinate grids. AshTL is currently in alpha development (some features may not work correctly, and interfaces are likely to change). While in alpha and beta development, AshTL is licensed under AGPL v3+. Stable releases will include an exception so that AshTL itself will always be AGPL, but will not force code that uses it to be. -

Behaviour Control Framework
A C++ framework that uses inhibition trees for behaviour control.
The Behaviour Control Framework is a generic platform-independent C++ framework that implements a control architecture consisting of a hierarchical network of behaviour layers. These layers each contain behaviours that can inhibit one another and interact to achieve control. A full discussion of the structure and ideas behind this framework can be found in the Doxygen documentation that comes with the release. This documentation is well worth a read before you decide if the library is for you! The structure and implementation of this library focuses on the application of the inhibition-based behaviour control architecture to real-time control loops, but can reasonably be adapted for a wide variety of other artificial intelligence applications. Emphasis has been placed on having very low overhead so as not to hurt overall system performance, while still maintaining ease of use. I welcome all feedback, suggestions and bug reports!
