A whole-program optimizing compiler for Standard ML
MLton is a whole-program optimizing compiler for Standard ML. MLton generates small executables with excellent runtime performance, utilizing untagged and unboxed native integers, reals, and words, unboxed native arrays, fast arbitrary-precision arithmetic based on GnuMP, and multiple code generation and garbage collection strategies. In addition, MLton provides a feature rich Standard ML programming environment, with full support for SML97 as given in The Definition of Standard ML (Revised), a number of useful language extensions, a complete implementation of the Standard ML Basis Library, various useful libraries, a simple and fast C foreign function interface, the ML Basis system for programming with source libraries, and tools such as a lexer generator, a parser generator, and a profiler.
The FOX (Free Open *X) toolkit is a lightweight replacement for GNU's userland mainly on Linux, based partially on code ported from NetBSD.
andfs is meant to be a filesystem layer for data dedupe and compress
andfs is meant to be a BSD licensed "filesystem layer" that can be backed by any other filesystem. It is meant to incorporate very easy to use, robust, extremely fast and flexible filesystem block level deduplication and compression. andfs is meant to be compatible with Linux and NetBSD.
