Free there is no need software for linux

Open Aureal Linux Driver is a fork of Aureals own soundcard drivers for the Vortex 2, Vortex 1 and Vortex Advantage. It is built with the goals of making the drivers more Open Sound System (OSS) compliant, more stable, and supporting later kernels.
Installing the Driver
1. Unpack the distribution:
tar xvzf aureal*.tar.gz
2. Change to the driver directory and become root:
cd aureal*
su
3. Edit the Makefile to suit your system (SMP, CPU type, etc)
4. Type the following install commands:
If you have an 8830-based (Vortex 2) card:
make install
If you have an 8820-based (Vortex 1) card:
make install20
If you have an 8810-based (Vortex Advantage) card:
make install10
There is no need to reboot.
Note: if you get "unresolved symbol" errors during the install, rebuild your kernel with sound support (soundcore) built in (not a module).
Enhancements:
- Works with kernel 2.4.0

tinc is a Virtual Private Network (VPN) daemon that uses tunnelling and encryption to create a secure private network between hosts on the Internet.
tinc is Free Software and licensed under the GNU General Public License.
Because the VPN appears to the IP level network code as a normal network device, there is no need to adapt any existing software. This allows VPN sites to share information with each other over the Internet without showing any information to others.
Main features:
- Encryption, authentication and compression
- All traffic is optionally compressed using zlib or LZO, and OpenSSL is used to encrypt the traffic and protect it from alteration with message authentication codes and sequence numbers.
- Automatic full mesh routing
- Regardless of how you set up the tinc daemons to connect to each other, VPN traffic is always (if possible) sent directly to the destination, without going through intermediate hops.
- Easily expand your VPN
- When you want to add nodes to your VPN, all you have to do is add an extra configuration file, there is no need to start new daemons or create and configure new devices or network interfaces.
- Ability to bridge ethernet segments
- You can link multiple ethernet segments together to work like a single segment, allowing you to run applications and games that normally only work on a LAN over the Internet.
- Runs on many operating systems and supports IPv6
- Currently Linux, FreeBSD, OpenBSD, NetBSD, MacOS/X, Solaris, Windows 2000 and XP platforms are supported. See our section about supported platforms for more information about the state of the ports. tinc has also full support for IPv6, providing both the possibility of tunneling IPv6 traffic over its tunnels and of creating tunnels over existing IPv6 networks.
Enhancements:
- This release fixes some memory and resource leaks, and makes network sockets non-blocking under Windows.

IOC::Proxy::Interfaces is a IOC::Proxy subclasss to proxy objects with a given interface.

SYNOPSIS

use IOC::Proxy::Interfaces;

my $proxy_server = IOC::Proxy->new({
interface => AnInterface,
# ... add other config values here
});

$proxy_server->wrap($object);
# our $object is now proxied, but only the
# methods which are part of the interface
# will work, all others will throw exceptions

$object->method_in_interface(); # works as normal

$object->method_not_in_interface(); # will thrown an exception

This is a subclass of IOC::Proxy which allows for the partial proxing of an object. It will only proxy the methods of a given interface, all other methods will throw a IOC::MethodNotFound exception. This could be used to (in a very weird way) emulate the concept of upcasting in Java, it is also somewhat like the idea of using interfaces with Dynamic Proxies in Java as well (see the article link in "SEE ALSO").

This proxy can be useful if you need to have an object strictly conform to a particular interface in a particular situation. The interface class is also pushed onto the proxies @ISA so that it will respond to UNIVERSAL::isa($object, Interface) correctly. Keep in mind that there is no need for the object being proxied to have the interface in its @ISA prior to being proxied. The proxy is dynamic and only requires that the object conform to the interface when it is being wraped but the proxy object.

mezoGIS project is a GIS application, a graphical interface to query and analyse spatial data. mezoGIS does not store or compute data directly, but operates external PostGIS databases. The goal of mezoGIS is to provide a tool for geo-spatial analysis with PostGIS, through on-the-fly SQL queries as well as through larger, external plugin scripts.
There are other, excellent open source applications that can display PostGIS data sets (like QGis or GRASS). Those projects, however, expect properly indexed tables as an input, and dont provide a built in functionality to launch SQL queries. The focus of mezoGIS is to stay close to the SQL workflow: Spatial queries are launched through manually entered SQL commands, and result sets containing geometry are displayed as map layers.
The first public release of mezoGIS was in march 2006. mezoGIS is entirely written in the python programming language, for gtk+. It works fine on the GNOME Desktop on linux, and has not yet been tested on other desktops or platforms.
Main features:
- Fast SQL queries: SQL commands and queries can be entered and sent to PostGIS within mezoGIS. Common SQL tasks and commands can also be accessed though context menues.
- View any kind of result: SQL queries yield result tables. If such a table contains geometric data, mezoGIS will display it in a map. There is no need to copy the data into a table or to create spatial indices. This is very useful for on-the-fly geoanalysis.
- Map creation: Result sets can be overlayed and layouted to create elaborate maps, the display engine currently has rough support for transparent colours, line styles, and symbols.
- Plugin engine: Plugin scripts written in python can be loaded and executed. The API is only a very rudimentary implementation, and will be subject to substantial change.
- XML file format: Projects are saved into an XML file format. The data itself is not stored, and must be reloaded from the database after loading.

Unison is a file-synchronization tool for Unix and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.
Unison shares a number of features with tools such as configuration management packages (CVS, PRCS, Subversion, BitKeeper, etc.), distributed filesystems (Coda, etc.), uni-directional mirroring utilities (rsync, etc.), and other synchronizers (Intellisync, Reconcile, etc).
Main features:
- Unison runs on both Windows and many flavors of Unix (Solaris, Linux, OS X, etc.) systems. Moreover, Unison works across platforms, allowing you to synchronize a Windows laptop with a Unix server, for example.
- Unlike simple mirroring or backup utilities, Unison can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are propagated automatically. Conflicting updates are detected and displayed.
- Unlike a distributed filesystem, Unison is a user-level program: there is no need to modify the kernel or to have superuser privileges on either host.
- Unison works between any pair of machines connected to the internet, communicating over either a direct socket link or tunneling over an encrypted ssh connection. It is careful with network bandwidth, and runs well over slow links such as PPP connections. Transfers of small updates to large files are optimized using a compression protocol similar to rsync.
- Unison is resilient to failure. It is careful to leave the replicas and its own private structures in a sensible state at all times, even in case of abnormal termination or communication failures.
- Unison has a clear and precise specification.
- Unison is free; full source code is available under the GNU Public License.

Stratos PHP Framework is an open-source, object-oriented web application framework that facilitates the rapid development of well-organized, secure, and maintainable PHP web applications. Stratos PHP Framework frees you from working on tedious, routine tasks, and allows you to focus on specific software requirements.
Main features:
Minimal Configuration
- The Stratos Framework is completely configurable from the web using the Developers Toolkit. This means you can spend less time getting set up and more time developing your applications.
- Object-Relational Mapping
- Using the StratosData plugin, you can easily map SQL tables to data objects. StratosData allows you to access Oracle, MySQL, SQL Server, SQLite, and other databases without writing any SQL statements!
Scaffolding
- Stratos can automatically generate CRUD (Create, Retrieve, Update, Delete) interfaces for your tables. This means you can kick-start your application by generating default actions and views for manipulating your data. The generated actions and views can then be modified to meet your specific needs.
Define Views in PHP
- Stratos does not require you to learn a separate templating language in order to define your views. All views are created using PHP by default, so there is no need to learn a separate syntax and introduce additional overhead for the sole purpose of creating a view.
Compatibility
- Stratos is compatible with both PHP4 and PHP5. This means that your applications will run on the majority of web hosts. Stratos has been thoroughly tested on a variety of operating systems and databases.
Performance
- Stratos was designed from the ground up to be fast. The framework has built-in caching capabilities that you can easily utilize from within your applications. When using the StratosData plugin, you can speed up your applications even further by caching database information to disk.
Ease of use
- Unlike many frameworks, Stratos does not have a steep learning curve. Its easy to get started developing web applications using Stratos. Simply download the latest release, install Stratos on your server, and create an application!
Enhancements:
- This release includes major updates and a handful of new features, bugfixes, and performance enhancements.
- Enhancements include an improved approach to creating action controllers, simplified data objects, data object event functions, automatic data object validation, complete removal of the XML config files, improvements to the plugin architecture, and a new look-and-feel for the Stratos control panel.
- Stratos 1.0rc1 is not backwards compatible with 0.93.
- This release begins the 1.0 branch, and all future development on the 1.0 branch will be backwards compatible with this release.

Linux Bandwidth Arbitrator allows beginning-to-advanced network administrators to control bandwidth. It is designed to be completely turn-key in its default configuration. You just plug it into your network trunk, and it self configures and immediately starts slowing "bandwidth hogs".
It can be configured to target specific applications such as Kazaa, IMAP, and POP. It is compatible with the 2.4.25 kernel, ebtables, and brouter (bridging router). It also comes with denial of service protection.
Main features:
- Default mode is turnkey
- Fully Redundant using Linux built-in Bridging
- Plug it in, no administration needed
- Will automatically scale back heavy bandwidth users (such as p2p traffic) and "normal" users will see a 25 to 40 percent busy hour improvement for activities such as e-mail, chat, and web surfing. There is no need to do any administration, completely turnkey!
- Unique implementation allows you to limit incoming Internet traffic
- Arbitrator 3.x and up work fine with Netfilter on the same machine!
- Automatically scales to Dial Up, DSL, T1, 40mbs
- Determines your actual trunk speed and dynamically adjusts bandwidth limiting accordingly.
Enhancements:
- In this release, there is a new utility that allows a user to see how many connections are current for an existing IP address.
- This will aid operators in deciding which users on their networks are candidates for a connection limit rule.
