Free balancing software for linux

The laplace balancer forms a sinus wave out of a soundcards balance, making a horizontal sinus sound with the currently playing sound. This is a dynamic enhancement to stereo music because it adds a new 2-channel quality to mono music.
Enhancements:
- hardcore bug fixed

TA Spring is an open source project developing a new realtime strategy game.
Spring is a full 3D RTS game engine with good balanced content.
Games can be intense and the engine allows some diverse strategies.
At this moment the Spring engine is capable to run most (all) content that was available for the Total Annihilation engine.
Around 8 high profile mods have been made to run specificly on the Spring engine.
Spring is mainly a multi player game engine.
Some light AIs are available but they are not really challenging at this moment.
Spring runs on Windows and is stable. The Spring Linux ports runs alright but it cant connect to other Windows clients (yet) so Linux users are limited to single player.
The developers try to make Spring run natively on different platforms. (Windows, Linux, Mac and *BSD) And (try to) add features that modders request.
Main features:
- High resolution maps, viewable from all angles and ranges
- Dynamic map with craters from weapon and unit explosions
- Work with unit files from Total annihilation
- Realistic 3D trajectories for weapons
- Fully 3D air combat
- Several camera modes to suit different tastes
- Mod switcher
- Lobby Client
Enhancements:
- LUA related changes
- AI improvements
- balancing improvements
- lots of bugs fixed

mod_backhand is an Apache module that allows seamless redirection of HTTP requests from one web server to another. This redirection can be used to target machines with under-utilized resources, thus providing fine-grained, per-request load balancing of web requests.
Backhand is a project that was initiated in class at The Johns Hopkins University in The Department of Computer Science. After a simple proof of concept, written in C++, the project was pursued as a graduate qualifier project.
A proof of concept was realized, but a deployable product was needed. In order for public use, testing and, ultimately, acceptance, we wished to provide drop-in functionality in the most popular web server on the net.
mod_backhand was born. This drop-in module for the Apache Web Server provides a turnkey solution for intra-cluster redirection of HTTP on a per-request basis. The redirection is based on various system resources available within the cluster. This service is provided seamlessly, preserving remote host information for access/authentication purposes.
As with the methodology of Apache, the redirection mechanism can be enabled or disable for individual directories.
System resources are announced by the module to the cluster via ethernet broadcasts and/or IP multicasts. These resources are made available to the decision making algorithms that drive mod_backhand.
Supporting the following platforms:
- Linux (since release 0.5)
- Solaris (since release 1.0)
- BSDI (since release 1.0.5)
- (Net|Free|Open)BSD (since release 1.0.5)
- Linux (alpha fix) (since release 1.0.7)
- FreeBSD (since release 1.0.8)
- FreeBSD-4.x (since release 1.2.0)
- Windows NT through ntbhb (see related links) (since release 1.2.1)
Enhancements:
- Fixed brown-paper-bag problem with byBusyChildren. It was internally calling byLoad.
- Add diagnostics for erroneous MulticastStats entries -- Ben Laurie
- Setting no MulticastStats is fatal -- Ben Laurie
- Mac OS X resource acquisition fix -- Marquis Logan
- Use apache notes to prevent infinite recursion in the event that failure causes local handling and local handling is backhand_redirection.
- Allow the first argument in the two argument MulticastStats form to be a hostname (rather than IP).
- Various CRLF fixes from Kevin Walters.

GNS-3 is a graphical network simulator that allows you to design complex network topologies. You may run simulations, or configure each device, from a simple workstation to a powerful Cisco router.
To allows complete simulations, GNS-3 is based on two existing projects:
- NS-3 , a discrete-event network simulator for Internet systems, targeted primarily for research and educational use.
- Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems.
This application is an open source product that may be used on multiple platforms, including Windows, Linux, and MacOS X.
Main features:
- Design of high quality network topologies.
- Emulation of Cisco routers.
- Load-balancing on multiple hosts/hypervisors when in emulation mode.
- Topology import and export.
- Image exports (PNG, JPEG, BMP, XPM).
Enhancements:
- Hypervisor load-balancing is now used to address the per process limit problem (http://dynagen.org/tutorial.htm#_Toc165530762).
- Configuration of multiple nodes may be done. The user can change hostnames.
