Free 6.0 software for linux

1. Ultra-low latency (typically from 3 to 9 ms)
2. Full audio bandwidth (44.1 kHz and 48 kHz)
3. Stereo support
4. Packet loss concealment
5. Constant bit-rates from 32 kbps to 128 kbps and above
6. A fixed-point version of the encoder and decoder
7. The CELT codec is meant to close the gap between Vorbis and Speex for applications where both high quality audio and low delay are desired.

Enhancements:

• Has just been released, with many quality improvements, including better stereo coupling, better handling of transients, and better handling of highly tonal signals.
• Packet loss robustness has been improved through the optional use of independent (intra) frames.
• Supports a larger dynamic range, suitable for encoding 24-bit audio (float version only).
• There is also a very early VBR implementation.
  

Jakarta Projects goal is to provide commercial-quality server solutions based on the Java Platform that are developed in an open and cooperative fashion.

Tomcat 3.x is an implementation of the Java Servlet 2.2 and JavaServer Pages 1.1 Specifications.

Tomcat 4.x is an implementation of the Java Servlet 2.3 and JavaServer Pages 1.2 Specifications, and is a re-implementation of the Tomcat servlet engine from the ground up.

Neko is an interpreter and programming language. It has been designed to provide a common runtime for several different languages.
Learning and using Neko is very easy, but youre not supposed to directly program in Neko. Instead, you can write a generator from your preferred language to Neko and then use the Neko runtime to compile, run, and access libraries.
eko is a good way for language designers to focus on design and reuse a fast and well-designed runtime, as well as existing libraries for accessing filesystem, network, databases, xml...
Neko language syntax have been created with "easy to parse" and "easy to generate" in mind. It is not especially designed to be written by a programmer but more to be generated from a higher level language.
For example one could write easily a PHP-to-Neko or a Java-to-Neko that would generate equivalent code but using Neko syntax and semantics instead of PHP or Java ones.
In particular, there are not multiple levels of expression, as in C. Every statement is also an expression, and thus enable some constructs that are not possible in other languages (for example : return if(x) { ... } else { ... }). This make the generation to Neko from functional languages more easy.
he syntax is parsed using a left-to-right LL(1) parser. That means that after reading a token we have enough information to know which expresion it will produce. This enable very lightweight parser which is easy to improve without creating ambiguities.
Enhancements:
- A bug was fixed in JIT.
- Performance was improved.
- UI and process IO APIs were added.

sipX is a next generation IP PBX solution offering rich functionality combined with ease of use, installation, and administration. sipX is entirely based on the Session Initiation Protocol (SIP) and significant attention is paid to standards compliance and interoperability.
It combines all common calling features, XML-based SIP call routing, Web-based configuration, and integrated management and configuration of the PBX and attached phones and gateways.
It is a modular server-based solution that does not require any additional hardware, as it interoperates with any SIP compliant gateway, phone, or application.
Main features:
- Native SIP IP PBX Solution
- Voicemail
- Multiple auto-attendants
- Presence
- SIP call routing
- Web based management
- Scalable architecture

KScope is a Cscope frontend. KScope provides a source-editing environment for large C projects, such as the Linux kernel.
KScope is by no means intended to be a replacement to any of the leading Linux/KDE IDEs, such as KDevelop. First of all, it is not an Integrated Development Environment: it does not provide the usual write/compile/debug cycle supported by most IDEs. Instead, KScope is focused on source editing and analysis.
The most important difference, however, between KScope and common IDEs is that KScope is intended for use with projects written in C, i.e., in a functional-programming environment. Most IDEs specialise in object-oriented languages and are of little help to the C programmer. For example, displaying all functions in the Linux kernel as global objects in a "Classes" tree does not provide any meaningful information.
KScope, on the other hand, is built around an efficient mechanism for code-navigation, which allows the user to run queries on the code.
The types of queries KScope can run include:
- Get all references to a symbol
- Find the definition of a symbol
- Find all functions called by or calling to a function
- Find an EGrep pattern
- Find all files #including some file
- etc.
These queries are handled by an underlying Cscope process. KScope simply serves as a front-end to this process, feeding it with queries, and parsing its output into result lists. The items in those lists can later be selected to open an editor at the matching line.
Main features:
- Multiple editor windows (using your favourite KDE editor)
- Project management
- Front-end to most Cscope queries
- Tag list for every open editor
- Call-tree window
- Session management, including saving and restoring queries
- Works with externally-built cscope.out files
Enhancements:
- Many bug fixes
- Updated documentation

DbVisualizer project is a cross-platform database tool for all major relational databases. DbVisualizer enables simultaneous connections to many different databases through JDBC drivers.
Just point and click to browse the database structure, view detailed characteristics of database objects, edit table data graphically, execute arbitrary SQL statements or SQL scripts, reverse engineer primary/foreign key mappings graphically or why not let DbVisualizer chart your database with its advanced charting options.
The user friendly graphical interface in combination with the unique collection of features makes DbVisualizer the ideal choice for database administrators and developers.
Main features:
General
- The Database Objects Tree is now always visible in the main window
- The Monitor main tab has been moved to a separate window (launch it via Tools->Monitor)
- Now with support for Java 1.5
- Support for Oracle XMLType data type
- Now displays User Defined Types (UDT)
- Support for MySQL 5+
Connection
- Variables can now be used in the Connection details
- New tool properties, Require Userid and Require Password
SQL Commander
- Auto Completion support used to ease the editing of SQL statements by automatically displaying list of table and column names
- The new Execute Current operation is used to execute the statement at the cursor position
Grid Enhancements
- Quick Filter is used to easily limit the number of rows in a grid by showing only those matching a search word
- Calulate Selection is used to perform simple calculations on the selected cells. Useful primarly for integer data
