Pick a composition of asteroid. Pick a diameter. Pick a speed. Pick an angle of impact. Pick a location on the planet. Watch how much damage, what kind of damage, and what the blast radii would be.

Feeling morbid? Use this map to calculate the badness of a nuclear strike on the city of your choice.
Software that simulates weather crawls and bulletins from the 80's and 90's. Show weather conditions and weather almanac data just like the early days of cable television. Customizable data layouts and crawl messages. Written in C++; nobody's perfect. Still tries to be as lightweight and simple as possible.
Telehack is a simulation of a stylized arpanet/usenet, circa 1985-1990. It is a full multi-user simulation, including 26,600+ simulated hosts from the early net, thousands of files from the era, a collection of adventure and IF games, a working BASIC interpreter with a library of programs to run, simulated historical users, and more. Telehack is an interactive virtual museum that allows one to see what the Internet was like in the 1990s, when young hackers were browsing through different bulletin board systems and shell accounts. One can learn exactly how they hacked in a safe and simulated environment as well as view real documents saved from BBSes thanks to textfiles.com.

Nyuzi is an experimental GPGPU processor hardware design focused on compute intensive tasks. It is optimized for use cases like deep learning and image processing.
This project includes a synthesizable hardware design written in System Verilog, an instruction set emulator, an LLVM based C/C++ compiler, software libraries, and tests. It can be used to experiment with microarchitectural and instruction set design tradeoffs.
