  • Mes - GNU Project - Free Software Foundation
    GNU Mes brings a Reduced Binary Seed bootstrap to GuixSD and potentially to any other interested GNU/Linux distribution, and aims to help create a full source bootstrap as part of the bootstrappable builds effort.

    It consists of a mutual self-hosting Scheme interpreter written in ~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme. This mes.c is being simplified to be transpiled by M2-Planet.

    The Scheme interpreter (mes.c) has a Garbage Collector, a library of loadable Scheme modules– notably Dominique Boucher's LALR, Pre-R6RS portable syntax-case with R7RS ellipsis, Matt Wette's Nyacc –and test suite just barely enough to support a simple REPL and simple C-compiler: MesCC.

    Mes+MesCC can compile an only lightly patched TinyCC that is self-hosting. Using this tcc and the Mes C library we now have a Reduced Binary Seed bootstrap for the gnutools triplet: glibc-2.2.5, binutils-2.20.1, gcc-2.95.3. This is enough to bootstrap GuixSD for i686-linux and x8664-linux.

    Mes is inspired by The Maxwell Equations of Software: LISP-1.5 – John McCarthy page 13, GNU Guix's source/binary packaging transparency and Jeremiah Orians's stage0 ~500 byte self-hosting hex assembler.

    GNU Mes is free software, it is distributed under the terms of the GNU General Public Licence version 3 or later. See the file COPYING.

  • Last Resort Font EULA
    The Last Resort font is a collection of glyphs to represent types of Unicode characters. These glyphs are designed to allow users to recognize that an encoded value is one of the following:

       a specific type of Unicode character
       in the Private Use Area (no private agreement exists)
       unassigned (reserved for future assignment)
       one of the illegal character codes.

    These glyphs are used as the backup of "last resort" to any other font; if the font cannot represent any particular Unicode character, the appropriate "missing" glyph from the Last Resort font is used instead. This provides users with the ability to tell what sort of character it is, and gives them a clue as to what type of font they would need to display the characters correctly. (For more information, see The Unicode Standard, Section 5.3 Unknown and Missing Characters.)
    Ironically, it is under export control.

  • gopass is a simple but powerful password manager for your terminal.
    gopass is a rewrite of the pass password manager in Go with the aim of making it cross-platform and adding additional features. Our target audience are professional developers and sysadmins (and especially teams of those) who are well versed with a command line interface. One explicit goal for this project is to make it more approachable to non-technical users. We go by the UNIX philosophy and try to do one thing and do it well, providing a stellar user experience and a sane, simple interface.
