P-rout is a tool for collecting and viewing data from the various types of a solar energy appliance called PowerRouter, manufactured by Nedap N.V. The appliance is connected to the Internet and uploads data to an HTTP server (logging1.powerrouter.com) that is owned by the manufacturer, who provides another HTTP server where customers can view their data. This project does basically the same while keeping everything on the owner's premises. It provides a data collecting HTTP server to which the PowerRouter can upload. Data is stored in a PostgreSQL database and can be reviewed on a second HTTP server. It is intended to be installed on a single-board computer with two network interfaces.
OpenCog is an Open Source software project aimed at directly confronting the AGI challenge, based on mathematics and using biologically inspired algorithms, including algorithms for common-sense reasoning and machine learning. Components include natural language processing and speech generation, robotics, game control, and vision.
Coq au Vin is a blogging engine written in Chicken Scheme. It is designed to appeal to users who have basic Web development skills (i.e., who know HTML and CSS), are able to install their own server-side software, and would rather edit a template than press 105 buttons to customize their sites.
Upmf is a source-based package manager written almost completely in Scheme. The user is able to search, build, and remove packages. Since Scheme through GUILE is very extensible, the user can customize the procedures, or even exchange them with his own, if wanted. Packages are stored in their own self-contained directories and are incorporated into the filesystem with help of GNU Stow.
Nerd is an attempt to create a cross-platform scripting language that is based on Scheme and easy to embed, extend, and use. It's currently used in video game projects and is interpreted only. There are definite future plans to add a byte-code compiler and VM to it and to write proper documentation.
Libchop is a set of utilities and library for data backup and distributed storage. Its main application is chop-backup, an encrypted backup program that supports data integrity checks, versioning at little cost, distribution among several sites, selective sharing of stored data, adaptive compression, and more. The library itself, which chop-backup builds upon, implements storage techniques such as content-based addressing, content hash keys, Merkle trees, similarity detection, and lossless compression. It makes it easy to combine them in different ways. The ‘chop-archiver’ and ‘chop-block-server’ tools, illustrated in the manual, provide direct access to these facilities from the command line. It is written in C and has Guile (Scheme) bindings.
