Dave Gnukem is an open source retro-style 2D scrolling platform shooter, inspired by and similar to Duke Nukem 1. It currently runs on Windows, macOS, Linux and various other platforms. It is written in C++ using SDL library and it features an integrated level editor as well. This game is not really a clone or remake, it is probably most akin to a parody.

cpp-httplib is a C++11 cross platform HTTP/HTTPS library, with a focus on ease of use. This is a multi-threaded 'blocking' HTTP library. If you are looking for a 'non-blocking' library, this is not the one that you want.

Checks adherence to a given style, syntax errors and possible semantic issues. Supports on the fly checking of R code edited with RStudio IDE, Emacs, Vim, Sublime Text and Atom.

The Adaptable IO System (ADIOS) provides a simple, flexible way for scientists to describe the data in their code that may need to be written, read, or processed outside of the running simulation. By providing an external to the code XML file describing the various elements, their types, and how you wish to process them this run, the routines in the host code (either Fortran or C) can transparently change how they process the data.

a minimal but practically usable implementation of a wlroots on-screen keyboard in legible C. This will only be a keyboard, not a feedback buzzer, led blinker, or anything that requires more than what's needed to input text quickly. The end product should be a static codebase that can be patched to add new features.

This is the Phobos standard library that comes with the D2 compiler.
