NimBorg is a library for accessing Lua and Python libraries from within Nimrod code. It wraps the C API of these languages with macros which make the code far more readable than the low-level API, and also automatically handles the memory management interface of these languages so that objects aren't deallocated as long as they're accessible from your Nimrod code.
Flora is a minimalistic but very powerful NoSQL database. It is easy to understand with data readable by both humans and machines, schemaless, Lua-scriptable, remotely accessible through TCP, and portable. It is especially suited for A. I. tasks, and a longer-term goal is support for "natural language" queries.
