The tower project began when Neal Stephenson started asking a simple question: how tall can we build something? As he started working with structural engineer Keith Hjelmstad, it turned out that this question has some surprising answers. To learn more about the project or get involved, check out the https://hieroglyph.asu.edu/?gpages=tower-project.
Fennel is a programming language that brings together the speed, simplicity, and reach of Lua with the flexibility of a lisp syntax and macro system.
Full Lua compatibility: Easily call any Lua function or library from Fennel and vice-versa.
Zero overhead: Compiled code should be just as efficient as hand-written Lua.
Compile-time macros: Ship compiled code with no runtime dependency on Fennel.
Embeddable: Fennel is a one-file library as well as an executable. Embed it in other programs to support runtime extensibility and interactive development.
Anywhere you can run Lua code, you can run Fennel code.

A password manager. It's a lot like pass ("the standard unix password manager") - which I have been using up 'til now - but it uses age instead of GPG to do the heavy lifting. Written in Ruby
Dylan is a multi-paradigm functional and object-oriented programming language. It is dynamic while providing a programming model designed to support efficient machine code generation, including fine-grained control over dynamic and static behaviors.
