Free balance software for linux

Balance is our suprisingly successful load balancing solution being a simple but powerful generic tcp proxy with round robin load balancing and failover mechanisms.
Balance behaviour can be controlled at runtime using a simple command line syntax.
Balance successfully runs at least on Linux(386), Linux(Itanium), FreeBSD, BSD/OS, Solaris, Cygwin, Mac-OS X, HP-UX and many more.
Balance is Open Source Software and released under GPL licensing terms.
Balance has been released the first time in June 2000 and has just celebrated its fifth anniversary.
Enhancements:
- A bug in the autodisable functionality has been fixed.
- The manual page has been updated.

Crossroads is a load balance and failover utility for TCP-based services.
Crossroads Load Balancer is a daemon program running in userspace and features extensive configurability, polling of backends using "wakeup calls", detailed status reporting, "hooks" for special actions when backend calls fail, and more.
It is service-independent; it is usable for HTTP(S), SSH, SMTP, DNS, etc.
Crossroads is a daemon that basically accepts TCP connections at preconfigured ports, and given a list of back ends distributes each incoming connection, so that a client process is served.
Additionally, crossroads maintains an internal administration of the back end connectivity: if a back end isnt usable, then the client request is handled using another back end. Crossroads will then periodically check whether a previously not usable back end has come to life yet. Also, crossroads can select back ends by estimating the load, so that balancing is achieved.
Using this approach, crossroads serves as load balancer and fail over utility. Crossroads will very likely not be as reliable as hardware based balancers, since it always will require a server to run on. This server, in turn, may become a new Single Point of Failure (SPOS). However, in situations where cost efficiency is an issue, crossroads may be a good choice.
Furthermore, crossroads can be deployed in situations where a hardware based balancing already exists and augmenting service reliability is needed. Or, crossroads may be run off a diskless system, which again improves reliability of the underlying hardware.
This document describes how to use crossroads, how to configure it in order to increase the reliability of your systems, and how to compile the program from its sources. This document is also available in PDF format.
Usage:
Crossroads is started from the commandline, and highly depends on /etc/crossroads.conf (the default configuration file). It supports a number of flags (e.g., to overrule the location of the configuration file). The actual usage information is always obtained by typing crossroads without any arguments. Crossroads then displays the allowed arguments.
This section shows the basic usage.
- crossroads start and crossroads stop are typical actions that are run from system startup scripts. The meaning is self-explanatory.
- crossroad status reports on each running service. Per service, the state of each back end is reported.
- crossroads tell service backend state is a command line way of telling crossroads that a given back end, of a given service, is in a given state. Normally crossroads maintains state information itself, but by using crossroads tell, a back end can be e.g. taken off line for servicing.
- crossroads services reports on the configured services. In contrast to crossroads status, this option only shows whats configured -- not whats up and running. Therefore, crossroads services doesnt report on back end states.
- crossroads sampleconf shows a sample configuration on screen. A good way of quicky viewing the configuration file syntax, or of getting a start for your own configuration /etc/crossroads.conf.

Sharedanced provides a tool to share PHP sessions between load-balanced servers.

Sharedanced is a high-performance server that centralizes ephemeral key/data pairs on remote hosts, without the overhead and the complexity of an SQL database.

It was mainly designed to share caches and sessions between load- balanced PHP Web servers.

Access to a Sharedance server is trivial through a simple PHP API and it is compatible with the expectations of PHP 4 and PHP 5 session handlers with no code change.

CalcRogue project is a Rogue-like for calculators, Palm, and PCs.
CalcRogue is based on the Unix game Rogue and those similar to it, collectively known as "roguelikes". They involve a character which can move around, attack monsters, collect magical items, maybe cast spells, and gain levels.
The dungeons are randomly generated, so the areas are always fresh, and the difficulty is such that it never gets too easy. (Note: CalcRogue is not derived from Rogue.)
Main features:
- Complex, randomly generated levels
- Overworld map, towns, and quests
- Spells and magically summoned minions
- Easy to use interface with tutorial
- Line of sight/lighting calculation
- Four-color grayscale graphics
- Complete inventory management system
- Wide variety of magical scrolls, potions, wands, rings, amulets and spells
- Missile combat with bows, crossbows or thrown potions
- Compressed saved games
- In-game help
- Hidden traps and doors
- Five different player classes
- Varied monsters with special powers
- Gold and shopping
- High-score listing
Enhancements:
Features
- Finished the tower quest, for wizards and necromancers. No spoilers in this changelog, but it involves lots of cool stuff.
- Checkpoint saves. A backup saved game is automatically made whenever you move to a new level, and restored if the game crashes.
Bug fixes
- (PalmOS) Fixed a stack overflow in the bytecode interpretter which caused crashes all over the place.
- (PalmOS) Fixed infinite prompt loop when running into a peaceful creature
- Fixed missing exit from tower area
- Fixed bug which could cause disconnected areas with the big-map generator
- Monsters wont be generated in the wilderness area
- Fixed bug that allowed duplicating items
- It is no longer possible to throw equipped non-missile weapons
Misc
- Balance changes to make the necromancer stronger

Audio::LADSPA::Network is a semi automatic connection of Audio::LADSPA::* objects.

SYNOPSIS

use Audio::LADSPA::Network;
use Audio::LADSPA::Plugin::Play;
sub subscriber {
my ($object,$event) = @_;
$object = ref($object);
print "Recieved event $event from $objectn";
}
Audio::LADSPA::Network->add_subscriber(*,⊂scriber);

my $net = Audio::LADSPA::Network->new();
my $sine = $net->add_plugin( label => sine_fcac );
my $delay = $net->add_plugin( label => delay_5s );
my $play = $net->add_plugin(Audio::LADSPA::Plugin::Play);

$net->connect($sine,Output,$delay,Input);
$net->connect($delay,Output,$play,Input);

$sine->set(Frequency (Hz) => 440); # set freq
$sine->set(Amplitude => 1); # set amp

$delay->set(Delay (Seconds) => 1); # 1 sec delay
$delay->set(Dry/Wet Balance => 0.2); # balance - 0.2

for ( 0 .. 100 ) {
$net->run(100);
}
$sine->set(Amplitude => 0); #just delay from now
for ( 0 .. 500 ) {
$net->run(100);
}

This module makes it easier to create connecting Audio::LADSPA::Plugin objects. It automatically keeps the sampling frequencies correct for all plugins, adds control and audio buffers to unconnected plugins and prevents illegal connections.

It also implements an observable-type API via Class::Publisher that can be used to recieve notifications of events in the network. Amongst other things, this makes writing loosely coupled GUIs fairly straightforward.
