Retro is a modern, pragmatic set of Forths drawing influence from many sources. It clean, elegant, tiny, easy to grasp, and adaptable to many tasks.

It's not a traditional Forth. Drawing influence from colorForth, it uses prefixes to guide the compiler. From Joy and Factor, it uses quotations (anonymous, nestable functions) and combinators (functions that operate on functions) for much of the stack and flow control. It also adds vocabularies for working with strings, arrays, and other data types. Source files are written in Unu, allowing for simple, literate sources.

The mathematical functions log(x), exp(x), root[n]x, sin(x), cos(x), tan(x), arcsin(x), arctan(x), x^y, sinh(x), cosh(x), tanh(x) and Gamma(x) have been implemented for arguments x in the real domain in a native Java library on top of the multi-precision BigDecimal representation of floating point numbers. This supports scientific applications where more than the double precision accuracy of the library of the Standard Edition is desired. This is the source code accompanying DOI https://doi.org/10.48550/arXiv.0908.3030 for the Online Calculator.

Kona is the open-source implementation of the k3 programming language. k is a synthesis of APL and LISP. Although many of the capabilities come from APL, the fundamental data construct is quite different. In APL the construct is a multi-dimensional matrix-like array, where the dimension of the array can range from 0 to some maximum (often 9). In k, like LISP, the fundamental data construct is a list. Also, like LISP, the k language is ASCII-based, so you don't need a special keyboard.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

This package provides a suite of command-line utilities for creating and manipulating epub book files. Included are: epubmeta, epubname, epubzip.

This StumpWM Module provides modeline support for a battery indicator.

Gerbil is an opinionated dialect of Scheme designed for Systems Programming, with a state of the art macro and module system on top of the Gambit runtime. The macro system is based on quote-syntax, and provides the full meta-syntactic tower with a native implementation of syntax-case. It also provides a full-blown module system, similar to PLT Scheme's (sorry, Racket) modules. The main difference from Racket is that Gerbil modules are single instantiation, supporting high performance ahead of time compilation and compiled macros.

Decentralised, minimalist microblogging service for hackers.

Mikmod is a module player and library supporting many formats, including mod, s3m, it, and xm. Originally a player for MS-DOS, MikMod has been ported to other platforms, such as Unix, Macintosh, BeOS, and Java.

Unixodbc is a library providing an API with which to access data sources. Data sources include SQL Servers and any software with an ODBC Driver.

Library for parsing and manipulating epub document metadata. Supports epub versions 2 and 3. This library was constructed by studying the IDPF specifications for epub documents found here <http://www.idpf.org/epub/20/spec/OPF_2.0.1_draft.htm> and here <http://www.idpf.org/epub/30/spec/epub30-publications.html>.

Frotz is an interpreter for Infocom games and other Z-machine games in the text adventure/interactive fiction genre. This version of Frotz complies with standard 1.0 of Graham Nelson's specification. It plays all Z-code games V1-V8, including V6, with sound support through libao, and uses ncurses for text display.
