Free open source groupware software for linux

HCS Open Source Project consists of a do-it-yourself home automation hardware and software system.

The HCS Open Source Project is a stand-alone home automation control system which consists of hardware (main controllers and remote networked controllers) and software to monitor and control various devices around your house.

The current plans support using wired and wireless X10 modules, as well as analog, digital, and voice input and output. Once the HCS is programmed, the use of a PC is not required.

CS stands for Home Control System. Originally designed by Steve Ciarcia for the article "Home Run Control System" for Byte magazine.

What is the HCS II? The HCS II is an expandable, network-based (RS485), intelligent-node, industrial-oriented supervisory control system intended for demanding home control applications.

The HCS incorporates direct and remote digital inputs and outputs, direct and remote analog inputs and outputs, real-time or Boolean decision event triggering, X-10 transmission and reception, infrared remote control transmission and reception, remote LCD displays, and a master console.

The HCS II system architecture consists of a central supervisory controller (SC) connected to up to 32 other functional modules (called links) via a RS485 serial network. The SC and the COMM-Links can operate independently and dont need each other to function.

This allows easy testing or incorporation as intelligent subsystems in other control equipment. Initially the subsystems links all shared a comon 8031 controller board (generically called a COMM-Link) with the I/O customized for each application.

Quake II Open Source project consists of the open source extended version of Quake II from Id.
Quake II Open Source is the open source version of the commercial first person shooter Quake II.
It has been updated from the commercial version for security, performance, and functionality.
For this to be of any use, you _must_ own a copy of Quake 2. The demo would also work, but you might as well buy the full thing now.
These modifications are intended for Linux users, as I do not have have access to other platforms.
Be sure to install SDL 1.2 (http://www.libsdl.org) if you want to use the softsdl or sdlgl drivers, or the sdlquake2 binary.
make will, by default, build both the debug and release files.
To build just the optimized binaries: make build_release
The resulting binaries are then put in releasei386.
System requirements:
- SDL

iRiver iFP is an user-space open-source driver for iRivers iFP flash portable MP3 players.
This project encourages open source driver development for iRivers iFP portable music players. Ifp-driver was started by Pavel Kriz with ifp-line, a command-line program and the first Free iFP driver. Today, the ifp-driver mailing list is a hub of discussion for iFP driver development: participants include everyone from authors of spin-off projects, to prospective owners/users.
Ifp-driver home projects:
ifp-line is the original command line utility and Midnight Commander plugin. Stable.
linux-filesystem a linux kernel module that mounts iFP devices as filesystems. Stable.
libifp a generic iFP support library. Stable.
