Free quality software for linux

SeaMonkey projetc is a web-browser, advanced e-mail and newsgroup client, IRC chat client, and HTML editing made simple -- all your Internet needs in one application.

The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as "Mozilla Application Suite".

Whereas the main focus of the Mozilla Foundation is on Mozilla Firefox and Mozilla Thunderbird, our group of dedicated volunteers works to ensure that you can have "everything but the kitchen sink" — and have it stable enough for corporate use.

ActivePerl project is the complete, quality-assured and ready-to-install Perl distribution for AIX, HP-UX, Linux, Mac OS X, Solaris, and Windows.
Whats included:
- Perl core
- Perl Package Manager
- Installers
- Complete online documentation
Enhancements:
- Release version of 64-bit ActivePerl for Linux, Solaris and Windows.
- Rewritten PPM client. The command line shell has been replaced by a graphical user interface.
- Bundles the Tcl and Tkx modules, plus a significant subset of the latest Tcl/Tk widgets.

Mumble is low-latency, high quality voice chat software primarily intended for use while gaming.

Mumble should compile and run the client out of the box on at least Ubuntu 6.06, and quite likely other distributions as well.

QAA is a XUL Mozilla Firefox extension that performs a user supplied test list on a Web application. Test sessions can be defined by example.
A report is generated when sessions are replayed.
Enhancements:
- This release can load and save .qaa files (Quality Assurance Agent file format), record a journey in the tested site using definition by example, and perform a test bench with a log style report.

Adaptive Quality of Service Architecture (AQuoSA) is an open architecture for the provisioning of adaptive Quality of Service functionality into the Linux kernel. The project features a flexible, portable, lightweight and open architecture for supporting soft real-time applications with facilities related to timing guarantees and QoS, on the top of a general-purpose operating system as Linux.
At the core of the architecture there is an adaptive resource reservation layer that is capable of dynamically adapting the CPU allocation for QoS aware applications based on their run-time requirements.
Timing guarantees are provided through an in-kernel reservation based process scheduler, whose services are exposed to applications through a well-designed API.
A supervisor performs admission control, so that admitting into the system new applications with timing guarantees does not affect the timing guarantees of already admitted applications. Also, it takes care of guaranteeing appropriate security policies in the assignment of timing guarantees to users and user groups, as configured by the system administrator.
A feedback-based QoS control layer may be optionally used by applications who want to keep their timing guarantees by using a CPU allocation that is continuously adapted according to their actual needs. This leaverages the programmer, within certain limits, to hard-code any particular reservation amount within the application, because the best allocation is found out automatically at run-time. Also, this enhances the possibilities for the system to host additional QoS controlled applications. The available control algorithms are well founded on formal scheduling models and control theoretical results.
Enhancements:
- This release introduces a couple of flags useful when creating servers. If QOS_F_PERSISTENT is enabled, a server is allowed to exist beyond detach of the last task. If QOS_F_SOFT is enabled, a server tasks are scheduled by the Linux default scheduler/policy, when outside of the server reservation.
- Also, various stability issues in destroying servers have been fixed, also thanks to a new release of the generic scheduler patch for the Linux kernel (gs-2.2).

Freeverb3 project is a high quality freeverb, nreverb and impulse response convolution reverb.

Freeverb3 includes high quality freeverb, nreverb and impulse response convolution reverb. Oversampling feature provides higher quality of audio processing.

This library includes XMMS / BMP beep media player / audacious plugins and sample programs.

Ctioga is a powerful command-line plotting system, to rapidly make publication quality graphs. Ctioga is based on the wonderful work by Bill Paxton, Tioga.

Ctioga has been designed with ease of use and extensibility in mind. It is based on the powerful Tioga plotting library.
