The Reactive Extensions for C++ (RxCpp) is a library of algorithms for values-distributed-in-time. The Range-v3 library does the same for values-distributed-in-space.The ReactiveX Observable model allows you to treat streams of asynchronous events with the same sort of simple, composable operations that you use for collections of data items like arrays. It frees you from tangled webs of callbacks, and thereby makes your code more readable and less prone to bugs.
Copyright (c) 2012-2016, Magnus Edenhill.librdkafka is a C library implementation of the Apache Kafka protocol, containing both Producer and Consumer support. It was designed with message delivery reliability and high performance in mind, current figures exceed 1 million msgs/second for the producer and 3 million msgs/second for the consumer.
Earth Enterprise is the open source release of Google Earth Enterprise, a geospatial application which provides the ability to build and host custom 3D globes and 2D maps. Earth Enterprise does not provide a private version of Google imagery that's currently available in Google Maps or Earth.Refer to the wiki for instructions on building from source on one of these platforms.
Blackbird Bitcoin Arbitrage is a C++ trading system that does automatic long/short arbitrage between Bitcoin exchanges.Bitcoin is still a new and inefficient market. Several Bitcoin exchanges exist around the world and the bid/ask prices they propose can be briefly different from an exchange to another. The purpose of Blackbird is to automatically profit from these temporary price differences while being market-neutral.

A modern, browser-based frontend to gdb (gnu debugger). Add breakpoints, view stack traces, and more in C, C++, Go, and Rust! Simply run gdbgui from the terminal and a new tab will open in your browser. gdbgui is easy to get started with yet supports scripting, and has terminal access while keeping the user interface in lock step with the underlying gdb process.
CefSharp lets you embed Chromium in .NET apps. It is a lightweight .NET wrapper around the Chromium Embedded Framework (CEF) by Marshall A. Greenblatt. About 30% of the bindings are written in C++/CLI with the majority of code here is C#. It can be used from C# or VB, or any other CLR language. CefSharp provides both WPF and WinForms web browser control implementations.CefSharp is BSD licensed, so it can be used in both proprietary and free/open source applications. For the full details, see the LICENSE file.
maim (Make Image) is a utility that takes screenshots of your desktop. It's meant to overcome shortcomings of scrot and performs better in several ways. Maim allows for a lot of unique and interesting functionalities. Here's an example of a few interactions.
A library for embedding interactive, customizable vector maps into native applications on multiple platforms. It takes stylesheets that conform to the Mapbox Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using OpenGL. Mapbox GL JS is the WebGL-based counterpart, designed for use on the Web.If your platform or hybrid application framework isn’t listed here, consider embedding Mapbox GL JS using the standard Web capabilities on your platform.
Builds vector tilesets from large (or small) collections of GeoJSON, Geobuf, or CSV features, like these.The goal of Tippecanoe is to enable making a scale-independent view of your data, so that at any level from the entire world to a single building, you can see the density and texture of the data rather than a simplification from dropping supposedly unimportant features or clustering or aggregating them.
Mal is a Clojure inspired Lisp interpreter.Mal is a learning tool. See the make-a-lisp process guide. Each implementation of mal is separated into 11 incremental, self-contained (and testable) steps that demonstrate core concepts of Lisp. The last step is capable of self-hosting (running the mal implementation of mal).
Annoy (Approximate Nearest Neighbors Oh Yeah) is a C++ library with Python bindings to search for points in space that are close to a given query point. It also creates large read-only file-based data structures that are mmapped into memory so that many processes may share the same data.To install, simply do sudo pip install annoy to pull down the latest version from PyPI.
Note: Now that the book is done, I'm not actively working on it. There are only so many hours in the day, and I have other projects that need my love, including a new book. This means I'm not responding to issues and pull requests here. However, I do intend to circle back and do a second edition at some point, so please do continue to file bugs.
Release under the BSD license, see "license.txt" for details. ChaiScript requires a C++14 compiler to build with support for variadic templates. It has been tested with gcc 4.9 and clang 3.6 (with libcxx). For more information see the build dashboard.
AutoHotkey is a free, open source macro-creation and automation software utility that allows users to automate repetitive tasks. It is driven by a custom scripting language that is aimed specifically at providing keyboard shortcuts, otherwise known as hotkeys. AutoHotkey_L started as a fork of AutoHotkey but has been the main branch for some time.
